OUTDOOR LIGHTING
From Coking Plant to Colorful Sculpture 32
Two design firms combined efforts for the lighting design of the Zollverein Coking Plant, in
Germany. According to Jonathan Speirs, the new building is a monumental industrial
sculpture, illuminated in different colors to indicate the juxtaposition of nature/power/process.
The project received a Paul Waturbury Award of Excellence for Outdoor Lighting Design.
Winging It 36
The Midwest Research Institute comprises two wings, each markedly different in
appearance. Mark Hershman fills us in on the thought process behind the design of
each wing, and the respective challenges the design team faced. In the process,
they earned an IIDA Paul Waterbury Award of Excellence.
Las Rozas Light Show 40
Ron Harwood, president of Illuminating Concepts, discusses his firm’s role in designing
the Hollywood Tower, a 90 ft tower that performs an operator-free synchronized sound
and light show in Heron City, an entertainment center in Las Rozas, Spain. This project
was awarded a Paul Waterbury Award for Outdoor Lighting Design Special Citation.
Millennium Masterpiece 44
The Millennium Dome was one of the icons celebrating the media-hyped “end of the millennium.” Lighted by the firm of Speirs and Major Ltd., the project was awarded a Paul Waterbury Award of Excellence for Outdoor Lighting Design. Mark Major details the firm’s work.
Revolutionizing the Rest Stop 48
Since the 1950s, service plazas have been familiar and valuable assets for travelers
along major U.S. highways. For years, these rest stops have maintained a
near-uniform appearance. Geraldine Kiefer describes the innovative design style
of the newly remodeled Ohio Turnpike travel centers.
LIGHT TRESPASS
Not in my Dark Yard 52
Light trespass has become an industry buzzword over the past few years. But, as
Edward Kramer explains, simply eliminating light trespass doesn’t solve the
whole problem. You also have to address light pollution.
Full Cutoff Lighting: The Benefits 54
Although the definitions for
cutoff lighting have remained
virtually unchanged for
nearly 30 years, a new
classification — full cutoff—
has been introduced.
Douglas Paulin details
the finer points of
this new terminology.

even three panes of pollution-encrusted glass. With
up-to-date screens, luminances of this magnitude produce barely-visible reflections, which are not likely to
distract or impede office workers.
I was surprised that he didn’t mention the thermal
consequences of glass with a low transmittance; incident IR can be reflected, transmitted or absorbed, and
most glasses of this type absorb incident IR within their
own volume, thereby conducting roughly half of that

to the environment. With careful choice of low-emissivity glass this can be avoided, but the summer heat-gain
consequences of specifying low-transmittance glass
are potentially very serious, especially in climates with
high solar gain and high ambient temperatures.
In my admittedly brief experience, the California climate consists of alternating sea mist and blazing sun
— and low-transmittance glass doesn’t seem to be
appropriate in either of these scenarios. Recent
research in the UK and Europe has concentrated on
glasses with clever internal structures which redirect
some light onto the ceiling while preserving the view
out, and on automated horizontal blinds (external blinds
are common in continental Europe).
Unfortunately both these options add significantly to
the capital and maintenance costs of the building,
but to me it seems axiomatic that, to cope with the
wide variation in weather conditions, the building
envelope should be similarly variable.

he section on office lighting in the new IESNA 9th
Edition Lighting Handbook makes the point that
illuminance is a poor criterion by which to design a lighting system and judge its effectiveness. While tidying my
study, I came across the following quotation from The
Illuminating Engineer (U.K. 1908). It makes the same
point as that made in the Handbook, nearly a century
later. The language used by the writer conjures up the
picture of an Edwardian gentleman with a high-starched
collar and three-piece suit, the bottom button of his
waistcoat being left undone after the fashion set by his
monarch, who was portly.
“It has been my experience in observing
the methods of work employed by persons
having to deal with lighting matters, to note
that there is often a decided tendency displayed to consider the technical (mathematical) side of the work as being the most,
and, in some cases, the all important. There
are persons who, in designing lighting systems, are seemingly lost unless they can work
out elaborate calculations from photometric
curves, which show them theoretically what
the variation and intensity of illumination will
be in a given space.
But values thus obtained give but little
idea as to what will be the effect of light on
the eye, which is a point of considerable
importance. It does not follow that because
we theoretically obtain a given distribution
and intensity of illumination, that the same
will be satisfactory to the eye, either from a
physiological or aesthetic standpoint. Therefore, something more than mathematical formulae must be considered, although I appreciate their usage in the work as a whole.”

n the architectural construction
world, the lighting specifiers —
the people who specify lighting
— are a very diverse group of people. The lighting specifier can be a
lighting consultant/designer, an
engineer, an interior designer, an
architect, or a design-build contractor. Less frequently, the lighting specifier can be the construc-

tion manager, and, of course,
sometimes the specifier can even
be the building owner. Lighting
consultants/designers also come
from a very diverse background,
including architecture, engineering, architectural engineering, interior design, theater and industrial
design, among others.
Where do we find lighting specifiers? The most obvious lighting
specifier group are independent
lighting consultants. The majority of
the lighting consultants in the U.S.
reside on the east and the west
coasts, and they typically belong to
the professional organization of
International Association of Lighting Designers (IALD), an international lighting specifier group of
about 700+ members.
There are also many larger architecture/interior design/engineering (AIE or AEI) firms across the
countr y who have their own inhouse lighting staff. These lighting
staffs are often part of the electrical
or interior design departments.
www.iesna.org
We can also find lighting specifiers within the many engineering
consulting firms as well.
An architectural or interior design
firm without an in-house lighting
staff will often have their project
team appoint one of the team members to do the lighting for the project if there is no budget for hiring
an independent lighting consultant.
In a worst-case scenario, the lighting design can often end up being
performed by either the project
electrical engineer, or sometimes
by the luminaire representative or
the manufacturer’s direct sales person. This is a situation that is difficult for all, since most sales representatives would prefer to assist
with the specification efforts, but
do not wish to be the designers.
Another specifier group with a
major influence on lighting specification and sales are the facility
managers of large corporations,
retailers and institutions. These inhouse specifiers can be very powerful because of their direct control over buying decisions. In
recent years, many lighting manufacturers have directed their attention to this group. However, it is
very important to understand most
of these facility managers — if not
all — hire outside consultants for
major projects or for the entire
actual design specification work
because they don’t often have the
in-house staff. In fact, because of
corporate downsizing, they are
doing less of the design/specification in-house today. Therefore, it is
important for sales people to call
on both the independent lighting
specifiers, as well as the in-house
facility specifiers.
All the lighting specifiers we have
discussed are very different people
with different likes, concerns and
needs. For example, the architect is
more concerned about the aesthetic quality of the architectural space
and how the different spaces interact with each other.
It is important to the architect
that the lighting product complement the architectural design. An
engineer, on the other hand, is more
concerned about the quantity
aspects of the design, such as the
quantity of light the luminaires provide, and the light distribution pattern. An interior designer is typical-
ly more concerned about how the
lighting product looks in the space
— especially the color and finish of
the product.
This does not mean that an archi-
SPECIFICATION SALES
STRATEGIES
tect would not be concerned about
the quantity aspect of a design, or
that the engineer is not concerned
about the quality aspect of the
design. However, as different professionals, they have different primary concerns. As a specification
sales person, if you have a product
that you want to sell to all these different people, you need to address
the different groups accordingly.
This includes the way you present
your sales pitch, relate to them and
the materials you provide for
accomplishing the specification
work. This is no easy task.

so that the volume of the tank is
proportional to its height.
Can you get a perfect piece of
toast by depending on the darkness
lever of a toaster?
Very few measuring devices are
linear. Perhaps the worst of all is the
human eye.
Do you remember the experiment
in high school physics where you
moved a light meter away from a
point source of light to demonstrate
that illumination varies as the
inverse square of the distance?
Well, the same test apparatus is
used in experimental psychology,
where observers are asked to move
a frosted glass panel away from the
point source until the brightness
drops to half its original value.
Everyone moves the panel twice
the distance away — where the
brightness has fallen to one-quarter,
not one-half.
Perception is influenced by psychology, and there are very few
straight line relationships in our
sense of vision and brightness.
There is the classic case of “Big
Brother is Watching” that skewed
the Hawthorne Experiment many
years ago, where workers increased
production under lower levels of illumination when they thought they
were being tested.
The result of the California energy crisis may put us all to the test
pretty soon. By being the canary in
the mine, the California governor,
legislature, energy commission, the
public service commission and the
utilities have demonstrated the
fable of the blind men and the elephant. Each party perceives the
task from a different perspective,
and the true picture is not what you
see, just like the gas gauge.
One of the other problems in
LD+A/April 2001
California was, while the utilities
were being compensated for their
stranded costs, when forced to sell
their outmoded generating plants,
they could not raise rates. But their
costs for power soared, sticking
them with debts that now threaten
to bankrupt them if not addressed
politically. But the citizenry in
California, with capped rates has no
incentive to conserve energy — so
they don’t.
By contrast, in New York, many
residents in co-ops and condos pay
for their electricity based upon the
size of their apartments, not their
usage of electricity. When co-op
boards decide to meter apartments
individually, electric bills decrease a
guaranteed minimum of 25 percent.

energy,
because some employees complain that working under lower
lighting levels reduces their ability
to work efficiently. Many business
owners justify including eye care in
health insurance plans to ensure
the eyesight of their employees is
properly corrected, at no cost to
the workers. If only they would use
that same reasoning to improve
“seeing” conditions.
I vividly recall doing a lighting
retrofit in a state office building several years ago, where we were able
to cut the load in half, yet increase
the illumination level by replacing
T12 lamps with half the number of
T8s, inserting new specular reflectors, and louvers and electronic ballasts in all the lighting luminaires.
One worker, coming back after a
vacation, complained that we had
cut the illumination level too much,
when in fact, we hadn’t gotten to
that office yet. Another worker
brought in a halogen torchiere, after
the lighting was improved, to
demonstrate that we had taken
something away (wattage) without
due compensation
Utility executives I’ve spoken to
realize that lighting energy conservation is essential for any comprehensive energy policy to succeed.
I like to make predictions so that I
have an incentive to hang around
long after my contemporaries have
retired and prove how smart I am.
(Of course if I’m wrong, you’ll
never hear it from me.) That’s why
I predict that DSM-type lighting
energy conservation plans are
coming back.
But technologically, we’re at the
point now where we can dim lighting from a central command, on-site
or off, to repond to the need for
energy curtailment without anyone
noticing and without any reduction
in worker efficiency. Also, as the
cost of power increases — as it
inevitably will — it becomes easier
to justify the occupant controlled
dimming of lighting on an economic
basis.
We keep forgetting that perception depends upon task contrast,
glare, eyesight, time, volumetric
brightness and the size of the task,
much more than it does on the illumination level. I just wish that we
could do as good a job improving
printed tasks and work place
ambiance as the PC monitor manufacturers have done in improving
their screens.
Remember, eyesight does not
have a linear relationship with illumination level, just like your gas
gauge. Less (light) can be More

20th century architecture owe their
lighting design to Richard Kelly.
Arguably, one of the founders of the
lighting design profession, Kelly’s
contributions have largely been hidden in the shadows of his most
notable collaborators: Louis Kahn,
Philip Johnson, I.M. Pei, John
Portman and Eero Saarinen.
So integrated were Kelly’s
efforts; and so seamless the blend
of architecture and lighting that
we tend to think of these architects as masters of light themselves, and miss the significance
of Kelly’s contributions. Purveyors
of architectural history will find
numerous books concerning the
works of Kahn, Johnson, and
Saarinen; but, to date, not a single
book exists on the long and distinguished history of Richard Kelly.
In an effort to provide the public with an opportunity to enter
the realm of lighting design,
become acquainted with the legacy of Richard Kelly, and to display
the breadth of his creative genius
in a museum quality setting; the
New York Section of the IESNA
funded the creation of an exhibit
in 1993.
Curated by Renee Cooley and
Matthew Tanteri, the exhibit was
developed after an exhaustive
review of Kelly’s voluminous
papers and archives. Thirty-six
works were eventually selected,
ranging from original pencil sketches to daylight pattern simulations.
An article entitled “The Great
Illuminator,” written by Philip
Cialdella and Carla Powell that discussed Kelly’s contributions, as
well as the exhibit appeared in the
May 1993 edition of LD+A.
The exhibit was initially shown in
the offices of Haines Lundberg
LD+A/April 2001
Waehler, New York, in 1993. Subsequently, the exhibit was displayed
twice to coincide with LIGHTFAIR
INTERNATIONAL in New York.
The Key Elements
In the exhibit, a brief biography is
followed by Kelly’s philosophy highlighted by his lighting trilogy: Focal
Glow, Ambient Luminescence, and
The Play of Brilliants. Possibly no
other aspect of Kelly’s work has
been more widely quoted and referenced as the lighting trilogy. Initially
published in 1955, the trilogy has
remained fresh, providing inspiration for succeeding generations of
aspiring lighting designers.
Most recently the trilogy has
been quoted by lighting designer
Gary Gordon and professor Marietta
Millet in their books: Interior
Lighting for Designers and Light
Revealing Architecture.
A series of drawings — pencil
sketches, color drawings and mechanical drawings — all combine to
demonstrate both the science and
the artistry of Kelly’s early investigations into portable lighting luminaire design. One drawing illustrates a full-size section of a floor
lamp, which is now in the permanent collection of the Metropolitan
Museum of Art.
The series on the Wireless
Chandelier designed for the Barbizon Plaza Hotel in New York,
1955, foreshadowed the entire
low-voltage cable lighting industry. The 192 lamps in this 12 ft
diameter chandelier were powered through the tensile tubes
themselves, with no wires in the
entire luminaire. The intricacy of
the structure also demonstrates
the genius of the long-term collaborative efforts between Kelly
and the luminaire manufacturer
Edison Price.
Another series deals with
Kelly’s association with Philip
Johnson and Ludwig Mies van der
Rohe as they explored the use of
www.iesna.org
glass in architecture. The transient nature of glass — at one
time transparent, at another
opaque — served to provide new
opportunities and challenges to
both architect and lighting designer. Kelly’s solutions were to have a
profound impact on the success of
the ultimate designs of such well
know buildings as Jonhson’s Glass
House and van der Rohe’s
Seagram Building. It is unfortunate that, in many cases, the integration that made these designs
so appropriate has been ignored,
leaving both architecture and
lighting disadvantaged.
The exhibit concludes with a
series on the collaborative investigations into the use of controlled
daylight in architecture between
Kelly and Louis Kahn. In two of the
last works by both designers, their
collective genius is expressed in the
Kimbell Art Museum and the Yale
Center for British Art. Here, sunlight
is used so successfully, that it
becomes a master piece on par
with the other works of art.
In this series, artistic studies of
forms and details share center
stage with the work of a fledging
tool — the computer. One panel displays a computer printout by an
engineer, Issac Goodbar, who had
just created a program that calculated the precise angles of the sun
— for two different ceiling forms.
The better of the two is now known
as the famous cycloid vault of the
Kimbell Art Museum.
The Exhibit Travels
Given the quality of the Richard
Kelly Exhibit and the potential of its
contribution to lighting education,
it seems inconceivable that the
exhibit could languish in a warehouse, but such was the case.
Originally conceived as a traveling
exhibit, the display had remained in
its specially designed crates since
1997. In 1999, the TCU Center for
Lighting Education formed an
alliance with the IESNA and Tarrant
Lighting to bring the exhibit to Fort
Worth, Texas, home of the Kimbell
Art Museum.
Tarrant Lighting was able to
secure funds through their association with Coooper Lighting and
General Electric to underwrite the
16
LD+A/April 2001
costs, and Texas Christian University provided the venue for displaying the exhibit. An educational
brochure that originally accompanied the exhibit was reprinted and a

poster was created to announce
the event to the community.
The 36 ft of display panels
required for the exhibit were rented
from a local company and fabric colors were selected to honor both the
exhibit and TCU. Finally, a reception
was promoted to provide a single
event to bring together the lighting
community to celebrate the twoweek exhibit.
The impact of the Richard Kelly
Exhibit cannot be overstated.
Design and lighting students spent
hours studying the various works,
often times bringing questions
back to faculty before returning to
the exhibit. The University community, students, faculty and administrators were able to view the exhibit and were impacted by both its
quality and the eloquent manner in
which it conveyed the importance
of light. The Metroplex lighting
community came to educate themselves and also brought clients
and customers as a way of speaking about the role of lighting. And,
finally, the brochure itself has
become a way of educating people
about the value of light in the built
environment — without being promotional to a particular company
or product.
As this article is written, the
Richard Kelly Exhibit has returned
to its warehouse; awaiting a call
to the IESNA of fice requesting
another journey.
It is my hope that this article will
infuse others with the incentive to
be the next stop. We often talk
about the need for more and better
lighting education. The Richard
Kelly Exhibit provides an opportunity to see lighting at its very best. I
look forward to the day when the
exhibit’s reservation list stretches
long into the future.

ine one of the more popular options
for communicating online: email.
Due to its tremendous speed and
widespread reach, email and other
forms of electronic communication
have all but replaced paper-based
interchange. Since the response
time can be immediate, email is
much less formal than traditional
paper-based media.
Getting Connected
Most organizations now rely on
email and its web-based relatives to
provide much of the day-to-day interaction between employees, suppliers and customers. Embracing interactivity is not only necessary to
remain competitive, but for survival
as well. Fortunately, there are email
options to address the needs of any
type of user. Creating a basic interactive presence requires minimal
effort, experience and expense.
Let’s take a look at some specific
scenarios and their email solutions:
Q. Is email service included
when I set up a website?
When you create a website and
hire an Internet Service Provider
(ISP) to host it, email is almost
always included with the package.
Basically, a host rents out space on
a server, which includes access to
the site residing in that space. This
includes access for you to revise
18
LD+A/April 2001
site content, for visitors to reach
the site via the web and for two-way
email communication. It allows
your email address to reflect your
website address (URL), as in
cmburns@springfieldpower.com
Q. What if I don’t have a website? How can I quickly establish
an email account?
It really depends on the level of
service you want. For most email
options, all you need is access to a
computer, or other device, that is
connected to the Internet. Other
Fortunately,
there are
email options
to address
the needs of
any type
of user
devices that provide web connections include handheld PDAs, Internet appliances and digital wireless phones. Some people use email
everyday without having their own
computer, by going online at work,
in libraries or even coffee shops.
The most common way to connect, however, is through an ISP.
You sign up, pay a monthly access
fee and you are ready to go. An
email account is provided free-ofchange, allowing you to set up one
or mor e email addr esses.
Companies like America Online
(www.aol.com), Earthlink (www.
earthlink.com), and AT&T WorldNet Service (http://download.
att.net/partners/) provide ubiquitous Internet access.
There are a number of regional
ISPs to choose from, but you might
have trouble accessing your account when outside the geographic
areas they cover. You almost certainly would be liable for any long
distance calling charges, if you
dialed in directly (see below).
Q. I don’t have a website or a
monthly web account with an ISP,
but I do have access to the Internet. What are my options for
setting up an email account?
It is very easy to set up an email
account without a monthly ISP subscription. You do not even need your
own computer; just access to a
web-connection. You can establish
email accounts and addresses with
a Web-Based Email service. Webbased email services allow you to
send and retrieve email via a your
web browser (like Netscape
Navigator or Microsoft Explorer)
from any web-connected terminal.
You enter the provider’s website,
set up an account and log in with
your user name and password. The
email provider stores all of your
messages for you and usually provides added services, such as
space to store files, online spellcheckers, personal address books
and distribution lists. As a tradeoff,
though, you may be subjected to
banner ads during throughout the
session.
Microsoft’s Hotmail (www.
hotmail.com) and Yahoo (http://
mail.yahoo.com) are two of the
more popular email services that do
not require an Internet Service
Provider (ISP) agreement and are
available to users at no cost.
Q. I have Internet access via a
monthly ISP subscription, but cannot access my email account
from outside my geographic area.
Is there any way to access my
mailbox?
You can often access a regional
ISP-based email account through
a POP Mailbox. POP Mail: POP
(point-of-presence) is what ISPs
commonly offer, so you probably
have at least one POP mail
account. POP Mail services store
your email messages on a remote
server until you are ready to collect them. You can connect to the
server at any time and download
your mail onto your computer.
Once you download the messages,
they are deleted from the server
and stored on your PC.
Unfortunately, if you have a
regional ISP provider, you may be
unable to dial into your mailbox
from outside a certain geographic
area or area code. However, you
www.iesna.org
should be able to dial-in with a secondary POP mail account. POP
mail is what ISPs commonly offer,
so you probably have at least one
POP mail account.
I dealt with this issue a few years
ago. My ISP was a regional telecom
company and I was unable to
access my account from certain
parts of the country. I was directed
by my ISP to a secondary POP service. The site allowed me to access
my primary account from any webconnected computer on the planet.
I now use a secondary POP service
called Webbox (www.webbox.
com) on a daily basis, for a whopping six dollars a year. Not only can
I access my existing email
accounts and check for new messages, but I can files (up to a total
of 20 megabytes) but also access,
revise and forward any some files I
have uploaded (up to 20 MB) to my
account. Another way to access an
existing email account is through a
site called Readmail (www.
readmail.com).
Q. I want an email address that
I can use on promotional material
and give out to clients and associates. Is it possible to set up a
permanent, dependable email
account that I can rely on, even if
I change my ISP?
You can set up a reliable email
address using a Mail Forwarding
(MF) service: This service automatically redirects messages sent to
one email address to an existing
email address, which is required
when using a forwarding service.
Think of it as a P.O. Box at the post
office: Even if you move, you can
still access your mail. This way, if
you change your ISP, you can easily
make the change with your MF
account, and it will automatically
be redirected. Forwarding services
also let you choose a memorable,
distinctive name. I currently use an
MF called Bigfoot (www.bigfoot.
com). The sender is only aware of
the “Bigfoot” address, not my main
email address, allowing me to
change primary email accounts at
will. Another MF provider is
NetForward (www.netfor ward.
com).
Most of us are aware of the
essential role that email plays in
www.iesna.org
our day-to-day communication. As
this column only scratched the
surface of email’s functionality, I
will undoubtedly revisit the subject in greater detail down the
road. In the meantime, feel free to

All too often, the human viewer
— with all of his strengths and
shortcomings — is overlooked
when the scene is lighted. Vision
has three components: light, the

stimulus for vision; the scene being
viewed; and the eye, the gateway to
understanding what is seen.
“One of the most useful operations in any sensing system, natural
or artificial, is a running normalization. In psychology, it is called adaptation; in engineering, it is automatic gain control. The idea is to adjust
the sensitivity to the average level
of input, so that all changes are
made to lie in the same limited
dynamic range.”2
Adaptation is the cornerstone of
vision. The field of view is always
less than the total surround. When
such fields are evaluated, adaptation may be greater or less than the
overall average, and luminances will
be non-uniform. But, uniform or not,
the weighted luminances (luminance x area) determine the adaptation if one’s directed attention
moves about. If fixed on one area, as
a draftsmen’s concentration on his
work, adaptation may take on the
higher adaption of that view, “near
the object of regard — very roughly
within about 10 degrees of it.”3
“The adaptability to the enormous range of intensity of illumination, which we meet in nature, is
secured: 1) by changing the opening and thereby the amount of light
admitted to the eye, by contracting
or opening the pupil; 2) by the
fatigue of the optic nerves (exposed
to high intensity of illumination, the
LD+A/April 2001
nerves become less sensitive, while
at low intensity they rest, and thus
become more sensitive); and 3) by
the logarithmic law of sensation.
The impression made on our senses, eye, ear, etc., is not proportional to the energy which produces the
sensation, that is, the intensity of
the light, the sound, etc., but is
approximately proportional to the
logarithm.4
Adaptation
is the
cornerstone
of vision.
The field of view
is always
less than the
total surround.
Visual benefits of adapation may
be impaired if glare occurs. “Glare is
the sensation produced by luminances within the visual field that
are sufficiently greater than the
luminance to which the eyes are
adapted to cause annoyance, discomfort or loss in visual performance or visibility.”5
Consideration of glare can only
confuse the determination of adaptation so it will not be pursued. It is
assumed that no excessive brightnesses are in the field of view.
“Human vision is duplex; man is
in the fortunate position of having
both photopic and scotopic vision
[and all adaptations between].”6
Sensitivities to acuity, color,
contrast and motion, all vary as
the adaptation changes. A given
luminance will be seen as differing
brightnesses as adapta tion
changes.
Light, the stimulus for vision, is
also electromagnetic energy. As
energy, it can be measured in can-
delas per steradian or lumens per
W. Light for vision has no measure,
but can be judged one area to
another. The eye is an excellent
comparator.
When an object first appears, it is
threshold detection, when it has
greater size or contrast, it becomes
sensation, and when it is recognized, it is perception.
What we read into strange unfamiliar shapes depends upon images
stored in memory. An excellent
example by the Canadian artist,
Ruth Kohler,7 is a weird blotch of
black on white. If one’s mind
regards it as a snow scene, the
shape becomes shadows of a farm
building. The process is a progression from sensation to perception.
Judgments of subjective properties are just that — judgments that
are never absolute, but vary with
the attitude and experience of the
observer.
The beauty of our ever changing
natural surroundings, including the
sun and the sky, influences our planning of lighting designs. The sun
changes direction; color is modified
continuously by rain, snow, fog,
clouds and a host of other factors.
Natural variations are infinite in
number.
Contrast as a visual sensation of
a difference in brightness, is often
defined by the equation: C =
Lo – Lb )/Lb, where C is constant, L
is luminance. Regrettably, there are
several alternate forms of this equation, which generate other results.
Luminance is the photometric from
which the sensation of brightness is
obtained. A light object against a
dark background is deemed a positive contrast; dark object on a light
background, a negative contrast.
Pereception of an object, represented by contrast, is often an immediate response by the average individual.
Parry Moon said, “It is a canon of
physics that a concept shall not be
defined in more than one way,” and
added, “The trouble is fundamental,
is inherent in the very fact that sensation does not reside in the world
of physics and thus, cannot be
treated as a physical quantity.”8
Fully diffusing surfaces show no
highlights, but do exhibit lightness
differences, which in color are
called tints and shades.

By emphasizing points of interest, suppressing unimpor tant
details, and composing the visual
elements, a design may deliver its
message more swiftly, accurately
and forcefully.
Some open questions: Do we see
in two dimensions and create the
third as a mental construct? If the
eyes are blind when the eye
changes its foveal concentration,
do we not always see a static twodimensional image? Isn’t our percept of motion derived from sequential static images? Wouldn’t blur
result if we could actually “see”
motion?
There is no more appropriate way
to conclude this discussion of vision
and the resulting sensation than to
quote, “From the point of view of
behavior, a specification of what a
subject does when he analyzes
‘sensation,’ and what he does when
he perceives is not now available.”9
Do we
see in
two
dimensions
and
create the
third as a
mental
construct?
I offer: Sensation occurs when the
stimulus is strong enough to pass
the absolute threshold of response,
but no strong enough to initiate the
process of perception, i.e., to
engage the mind, which will be the
subject of our next discussion.

REGIONAL
VOICES
Jeffrey Davis,
Northwest
Region RVP
After working in this industry for
20 years, I knew little or nothing
about the IESNA. When our region
was hosting the bi-regional conference in 1991, the Board was having
a hard time getting volunteers from
the section to help in the administration of the conference.
The then-president, who was a
friend of mine, asked me whether
I would consider lending some
time and energy. It seemed like a
good opportunity for me to work
with people I had known and/or
worked with in the past who knew
what I had to offer. By the time
the conference started, I was a
new member of IESNA.
We often talk about the importance of retaining membership. I
believe expanding membership
should be just as important. Asking
people to volunteer when they are
not current members is a great way
to gain new members. As in my
case, it’s a win-win situation: They
can make a valuable contribution to
their local section while they sharpen their own gifts and skills. In other
words, IESNA benefits from the volunteer’s expertise, and the volunteer returns to the workplace
empowered with the most recent
developments in the field.
IESNA has enhanced my career
by providing a variety of opportunities. If we can communicate this
message to our colleagues who are
not yet members we will be able to
expand our arena of influence and
our membership.
The benefits of volunteering do
more than simply enhance the
Society or one’s career; volunteers
help others realize their potential. I
am grateful for the members who
took the time to not only encourage
me, but to mentor me as well. It
was through the help of others that
I came to see how my contribution
could make a difference in my section. Because of the individuals who
were willing to give me some of
their time and attention, I have
been able to serve on the Board of
Managers, as treasurer, as vicepresident and as president. The

simple act of asking for my help on
one project and then giving me confidence and experience has resulted in my being able to make an
impact on both the regional level,
and now the international level as
regional vice-president.
I would like to take this opportunity to express thanks to my region,
particularly, my regional chairs.
As we go through seasons in our
careers, we also going through new
seasons in our lives. My father, who
is very close to me, has been seriously ill these last few months and
I have had less time to serve my
region. These members have
stepped up their efforts and taken
much of the burden from my shoulders, whether they realize it or not.
This is what being a part of and
serving with others in IESNA is all
about: making new friends and
sharing in their professional lives
and beyond.

Ballasts for
Barristers
Whether you’re part of a pit crew
for a Formula 1 racing team, or a set
designer for the Hollywood film industry, the element of a “team atmosphere” is always essential to accomplishing any task. Since 1954, the
law firm of Newton, Kastner & Remmel has been an example of this
team-first attitude.
Located in Mountain View, Calif., the
firm has advised Silicon Valley executives and local, national and international companies on a wide range of
legal issues, including stock options,
labor law, environmental issues and
individual compensation.
The legal rating service of Martindale-Hubbell has consistently awarded
the firm the highest possible rating for skill and integrity. It only seemed logical for the office surroundings to be worthy of the
same level of praise and recognition, both for its functionality and its appearance.
“Since our award-winning building was built in 1986, a variety of fluorescent lamps had been used to re-lamp office space,”
said Stephen Newton, founding partner. “This created a hodge-podge look and resulted in problems when lamps needed replacement. So, we decided to standardize the whole lighting system and began a study of existing lighting technology.”
Newton teamed with his lighting maintenance contractor. Tadco Supply, San Jose, Calif., and decided to install a new
electronic fluorescent lighting system. The new system includes 576 new 32 W T8 Fluorescent lamps and 260 new
MagneTek Triad B232I120RH reduced harmonic electronic ballasts, which replaced the already existing fluorescent lamps
and magnetic ballasts.
Newton said the firm was looking for light quality that would enhance the facilities for the 12 attorneys and support staff, as
well as be highly functional for prolonged periods of document review.
Because of the time and research involved, many companies underestimate the savings generated from lighting system retrofits and upgrades. Most lighting upgrades can save approximately 50 cents per sq ft, per year, with an average payback of 2.5
years. Lamp design, materials electronic ballasts and lighting control systems contribute
to lighting efficiency, reliability and quality.
With the use of electronic ballasts, the overall efficiency of the lighting system in the
building is improved, on average, between 20
and 40 percent.
“The reaction of the partners and staff to
the new lighting system has been very positive,” Newton said. “We decided to retrofit
the tenant space on the first floor of the building with the same lamp/ballast package we
used in our own offices.”

Bateman Sossman Advertising Agency purchased a small office building,
originally built in 1928, on the outskirts of downtown Memphis. The remodeling design of the interior of the building had to be extremely contemporary, to fit with clients’ expectations of the advertising product the company produces.
However, each production employee has varied tasks to complete in one
space, such as sketching, artistic design, copywriting both by hand and on
a computer, and — of course — brainstorming new ideas and themes.
Thus, the lighting design needed to also be flexible and functional.
It was decided that track lighting would be the main lighting choice,
with MR-16 fixtures of various types, plus chandeliers and cylinder softly lighting low footcandle areas, and PAR-30 downlights furnishing higher illumination levels. In offices on the second and basement floors, 2 x
4 fluorescent with 3-T-6 cool white lamps were utilized. Some of the first
floor executive offices also included downlights for the seating areas
and track lights for bookshelves and desks.
Overall, the lighting design for the entire building includes only six types of fixtures: track with MR-16 or 50W PAR-30
lamps in open-type fixtures; downlights 4 in. in diameter, with 50 W PAR-20 lamps; 6 in. round cylinders, pendant-mounted, with 150 W A-23 lamps; louvered RLM type chandeliers with 4-tube PL fluorescent lamps in glass enclosures (self-ballasted) or 150 W A-23 lamps; under cabinet lights with white acrylic lens, 1 in. deep; and fluorescent 2 x 4 fixtures with
3-T-6 cool white, 4 ft lamps
The first floor of the building is devoted to the artistic staff, while the second floor houses the executive offices and a large conference room. A smaller conference room, offices
and some storage areas are located in the basement.
The first-floor lobby has pendant-mounted chandeliers in front of the reception desk, while
the desk itself has track lighting mounted above it with MR-16 fixtures. All pendant-mounted fixtures throughout the first floor have their junction boxes and canopies mounted above
the egg crate ceiling and painted black. The pendant itself is also painted black to just above
the egg crate. Lighting track is surface-mounted on the bottom of the egg crate ceiling.
Corridors on the first floor are illuminated to 28 fc with the chandeliers. Each occupant of
the first floor offices has personalized his office to some degree by adding table or floor
lamps and/or floor-mounted uplights. The lighting track is segmented and on dimmers. Thus,
the office footcandle level varies as desired by the occupant.
Two side corridors lead from the lobby to a working desk area where employees cut and
paste ad mockups. The table is illuminated by a rectangular lighting track to 70 fc, while the
surrounding area is illuminated to 30 fc by pendant-mounted cylinders.
In the basement, there is a break room, which has a seating area illuminated to 30 fc
by downlights. There are counters and cabinets with under cabinet lights on one wall,
while the other wall has photographs showing ads and art work, illuminated by a lighting
track with the PAR-30 fixtures.
Next to the break room is a conference room, with
downlights, chandeliers and lighting track. Down the hall
from the break room is an archway with two wall
sconces leading to a private office area. The hallways
again have downlights, and the private offices have 2 x
4 fluorescents providing 80 fc.
In summary, it might seem that the selection of only
six different lighting fixtures would lead to monotony,
but a sense of lightness and airiness is evident
throughout, due to careful placement and use of the
fixtures. The lighting needs of both the creative and
executive staff have been met, along with the added
bonus of providing clients the impression of a “cutting
edge” advertising agency.

Paradise by the Hubcap Light
My father, Larry Maynard, inspired the NostalgaLite. He has a deep
love of classic muscle cars, typical of Baby Boomers. He raised me
with several cars in our garage and driveway, and my childhood was
spent visiting cruise-ins and car shows. When I was very young, my
father had a turquoise 1957 Chevy Bel-Aire convertible. Sadly, he sold
the car and has regretted it ever since.
Recently, I saw a 12-in. reflector awaiting a photometric test and
immediately thought, “That’s just the size of a hubcap.” I called
home and asked my father for a spare hubcap to a ’57 Chevy that
could be used for an experiment. Luckily, he decided to part with one.
I drew out several possibilities of how to light such an awkward piece of metal. Originally, I had wanted to make it a MR16 fixture, but the question of heat and directionality of light output was a major factor. I acquired a large, two piece reflector with trim and optical assembly.
The challenge was how to keep a heavy hubcap suspended below a recessed luminaire, while creating a lighting effect that
was neither gaudy nor unnoticed. The “spinner” of the hubcap was removed and the center, plastic cap was removed and
repainted. The center decal was cut out of the hubcap and 3 in. screws were placed through original holes drilled for the spinner. The spinner was then placed atop these screws creating an approximate 3 in. gap between it and the hubcap with a hole that would allow
light to filter through. The idea was to direct the light through this passage
and to catch it in the warm red plastic cap inside the spinner. Oblong holes
were also punched along the perimeter of the hubcap face to allow accent
light to spill through and highlight the curves of its design.
An H.I.D. 12 in. diameter downlight luminaire was used and converted
to a 42 W, triple tube compact fluorescent with electronic ballast. This particular light provided low heat, and a soft, even glow through the perforations in the hubcap. A red acrylic prismatic reflector was then envisioned
as a “non-lighting ‘mood’ element.”
I imagined a red, almost neon effect casting a warm glow behind this
hubcap. I knew, somehow, I wanted this piece to create a ring-like glow.
The 12 in. reflector was pushed inside the 12 in. acrylic reflector of the
downlight and the difference provided about a 3-in. ring extending
beyond the fixture. Two holes were drilled into the acrylic reflector to allow spring clips to pass through. Spring clips were
pop-riveted onto the inner face of the hubcap to provide a means of support.
Once everything was assembled, the hubcap proved to be too heavy for the spring clips. Stronger springs were attached to
each side of the luminaire, linking all of the spring hooks. This provided enough strength to hold the hubcap in place.
When placed in the drop ceiling in a test environment, the NostalgaLite provided a warm glow with satisfactory results.
Depending on the ambient lighting, the NostalgaLite can provide a deep red glow, or just merely a faint glow with light reflecting off of the shiny metal. When placed into the ceiling, the red reflector performed just as I had hoped it would. It formed a
ring approximately 3 in. tall flush to the ceiling. The hubcap was
attached to the bottom part of the ring. The effect was as if there
was a small, neon light circling the decorative piece.
After its debut, the fixture was then carefully wrapped in bubble
pack and placed in a large bag. (The luminaire itself was too large
to fit into any readily available boxes)
My father unwrapped his NostalgaLite, Christmas morning,
after months of wondering what I wanted with a hubcap. He was
surprised to see it light up. He had expected to find a clock looking back at him. The NostalgaLite remained illuminated underneath the Christmas tree as the presents were being passed
around to family.

Fiberstars Receives R&D Award
Fiberstars, Inc. of Fremont, Calif., has received a $2 million R&D Award from
the Advanced Technology Program (ATP) of the U.S. Department of Commerce
National Institute of Standards and Technology (NSIT). The money will go toward
developing a continuous manufacturing process for new technology fiber optics
designed primarily for lighting applications.
The new fiber can potentially offer significant performance and cost advantages for lighting systems, which can be up to five times more efficient than conventional lighting, at one-fifth the operating cost.
Fiberstars acquired the patents as part of its Unison acquisition last year.
The company estimates it will take close to three years and $3.4 million in
R&D to complete the work.
Fiberstars intends to combine the new fiber with future generations of its
new CPC technology, also acquired in the Unison deal. This optical innovation
will improve fiber optic illuminator efficiency by a factor of three over current
systems. Optical illuminators base on the CPC technology are expected to be
available in 2001.

INTERNATIONAL ILLUMINATION DESIGN AWARDS
FROM COKING PLANT TO
COLORFUL SCULPTURE
Two design firms combined efforts for the lighting design of the
Zollverein Coking Plant, in Germany. According to
Jonathan Speirs, the
new building is a
monumental industrial
sculpture, illuminated
in different colors to
indicate the juxtaposition
of nature/power/process.
The project received
a Paul Waturbury Award
of Excellence for
Outdoor Lighting Design.
(right) Concepts for Zollverein Kokerei
developed around the juxtaposition of
nature/power/process. A palette of
red and blue was chosen: Blue to light the
people viewing area, encouraging visitors to
look at the facility in a different manner;
and red to illuminate the facility itself,
evoking images of rust, fire and heat.
(opposite, top) The reflecting pool (measuring
3/4 of a mile) was an integral part of the concept.
The funds were only made available with one
month to go before completion.

he Zollverein Kokerei (Zollverein
Coking Plant) was not a typical
exterior project; in fact, it was
deemed by the client to be part of its Arts
program for the regeneration of an industrial heartland of Germany. Rather than
purely describing the solution, the development of the design ideas may be as
interesting to explain as the philosophy
and approach of our group.
In March 1998, the Lighting Architects
Group — Jonathan Speirs and Associates
(Edinburgh) and Speirs and Major
(London) received an invitation from IBA
Emsher Park to enter a competition for
the lighting design of the Zollverein
Kokerei in Essen, Germany.
The German Government-funded IBA
(Internationale Bau-Ausstellung) exists to
regenerate areas of Germany that have
fallen on hard times. IBA Emsher Park
differs considerably from the others in that it has a 10-year life span. The scheme was developed as a test case for new thinking
in energy conservation and land regeneration. The Ruhr valley has been in decline since the 1960s, and lately has been plagued
by both ecological, as well as social problems. IBA Emsher Park has been attempting to tackle both of these issues.
We visited the site and were guided around the project area by IBA. Unused since 1992, this amazing edifice once employed
2,000 people. It was more like an efficiently designed machine rather than a building or structure. The almost poetic “production line” was clearly expressed: from transportation of the coal to the facility, its local distribution and storage, and its
insertion into the coking ovens, to its removal as coke and then its ultimate onward distribution to nearby steel plants. This
became the inspiration for the lighting concept.
There was not one piece of decorative detail anywhere in the project. Every element of the building has a purpose and function and in this case it is very apt to quote a famous German émigré architect: “form follows function.”
The scale of the project — it takes about 40 minutes to walk around the structure — was an important aspect that drove
some of the design decision-making. This was in addition to the almost reverential status the client placed on the tall chimneys. In the Ruhr valley, they have no hills or mountains, so such a vertical statement was deemed to be an important landmark for the surrounding area
The concepts for the project were brainstormed in both of the Lighting Architects Group studios with the philosophical
“theme” of Nature/Power/Process providing the backbone of the ideas. Each studio generated sketches, details and Photoshop
images, and the entire proposal manifested
itself in a digital video presentation that included a clear explanation of the philosophy, supported by animation sequences.
Our intent was to create an image that was no
longer an industrial landscape, but rather, a
sculptural icon describing the form, materiality,
scale and revised perception of a 20th Century
monument regenerated for a different purpose:
that of a local landmark. To achieve this, a
monochromatic wash of red was selected to
enhance the corrosion of the steel superstructure of the ovens.
After being awarded the project, a series of
meetings and workshops were then organized
in the ensuing weeks, as the switch-on had to
coincide with a major temporary exhibition
that was being planned for the facility.
Then began the hard part: to transfer the
ideas into reality. There were several site tests
before the installation designs were formalwww.iesna.org

ized. Locally the design was engineered and overseen by
START Media.
One powerful idea presented at the competition stage was for
an 800 m long by 30 m wide reflecting pool. Between the
entrance road and the structure, the reflecting pool mirrors the
facades both by day and by night, creating ripple patterns of
white light across the battery of ovens.
The pool is a simple device of aluminium sheet, fully tanked with black bitumen, and responds as a mirror to reflect the building mass. When natural air movement contacts the surface, ripples effectively animate the main elevation.
Running parallel to the main façade is a road that separates the black
side (coke) of the facility and the white side (chemical). It was decided
that this road and linear viewing point presented a powerful opportunity to assist the public to look at the Kokerei differently, by heightening
their visual senses to enjoy the appearance and experience of the
Zollverein Kokerei more.
This was achieved by illuminating the road with blue metal halide
luminaires. These were located asymmetrically on the opposite side of
the road to the facility. This meant that, when looking at the 800 m long
row of ovens, the luminaires were behind the viewer, yet both the area
and the viewer were lighted in blue.
The main coking ovens themselves were cross lighted by asymmetric
metal halide floodlights with a red glass filter to give shadow and texture.
Different filters were tested to find a color that was not too orange, but
showed the graininess and patina of the metal doors.
The gas burners below the ovens are located in an area with a row of
glazed windows. These were backlighted, again with red, but this time
fluorescent luminaires were used. The chosen shade of red was a little
lighter than that used on the ovens.
The “landmark” chimneys were lighted in two ways. First, they were
washed with metal halide luminaires with red glass filters and linear
spreader lenses. Second, at the crown of the chimney a net of red LED
luminaires were installed. A total of 150 luminaires were used on each chimney. These randomly animate to surprise the passerby and intended to be the distant reference view. They are, in fact, visible from 15 miles away, much to the delight of the client.
In May 1999, the illumination of the Kokerei was formally switched on to coincide with the opening of the Sun, Moon and
Stars exhibition that was created within the heart of the coking plant. The public response to the project has been very positive
and the client is delighted with the results. The 800 LEDs (each one using only 2.5 W of power) located at the crowns of the
chimneys can be seen from more than 15 miles away, fulfilling the landmark criteria of the initial proposed brief.
The creative design process at the competition stage was a great stimulus for the entire design studio that contributed excellent
ideas. The rigorous holding to those original ideas through the design implementation and construction phases further added to
the clarity of the final image and offer proof of the strength in their simplicity
The designers: Jonathan Speirs BSc (Hons); Dip. Arch; RIBA; ARIAS; IALD; ELDA; FRSA trained as an architect and
has more than 17 years experience as an independent lighting consultant. He co-founded Lighting Design Partnership
(LDP) in 1984. In June 1992, he left LDP to form Jonathan Speirs and Associates in Edinburgh. In January 1993, he
opened a London office in association with Mark Major as the London-based office of the Lighting Architects Group.
He has been awarded a number of lighting awards, including a Guth Award and three Paul Waterbury Awards in 2000.

While the vestibule at the Midwest Research Institute physically links the two
buildings, the perforated wall acts as the representational link. High-output 3500K

INTERNATIONAL ILLUMINATION DESIGN AWARDS
WINGING IT
The Midwest Research Institute comprises two wings,
each markedly different in appearance. Mark Hershman fills us in
on the thought process behind the design of each wing, and the
respective challenges the design team faced. In the process, they
earned an IIDA Paul Waterbury Award of Excellence.
I
n an effort to forge Kansas City’s dream of being the focal
point of the world’s life science research, the Midwest
Research Institute (MRI) looked to lead the course with a
fresh architectural look. As a fixture in the Kansas City landscape since the mid-1950s, the world renowned research facility has occupied prime real estate north of the popular retail
mecca, the Country Club Plaza. Although situated not more
than 90 ft from the busy boulevard, the horizontal expanse of
the complex, in conjunction with the dated architecture gave
the facility undeserved anonymity.
If MRI was to be the city’s launching pad for future research
growth, it had to present itself in a more flattering light, figuratively and literally. Within the research community, MRI’s
advances in agent studies of the “Gulf War Syndrome” and
development of renewable energy sources were widely recognized. Despite its accomplishments, the MRI had not distinguished itself within the local architectural scene.
Enter Rafael Architects, Inc. (RAI). As a local architectural
firm known for more progressive designs, the firm was charged
with crafting an image to define the MRI as a leader in technology and research. The necessity to merge the past with the
future led RAI to the doorstep of Yarnell Associates Lighting
Design. Having collaborated on previous projects, the combined design team could present a comprehensive concept of
integrated architecture and lighting, where the individual
strengths of different areas of design reinforce one another.
In 1972, the Midwest Research Institute expanded from its
one lone building, originally constructed in 1955, to include a
similar one-and-a-half story Spencer building to complement
the existing Kimball wing. To reduce the daytime visual
breadth, RAI designed a vertically oriented central glass box
entry. The literal split between the two structures led to other
refinements that would further differentiate the two buildings,
despite their close proximity. To the Spencer side, or left side of
the entry, the architects developed a minimalist landscape
approach, complete with a formal display of trees and rock gardens leading to the vestibule.
It was the renovation to the Kimball wing that piqued the
interest of Yarnell Associates. Across the street and on axis, rises
the historical Nelson-Atkins Museum of Art, a majestic neoclassical edifice erected in 1933. The lighting design team wanted to mimic the classic philosophy of the columnar museum,
but wanted to apply it to a modern structure. New vertical
metal fins designed for the Kimball building are strongly delin-

eated by custom Q71MR16/C/NSP15 uplight fixtures with
remote transformers. The minimal 3 in. diameter by 5 in. high
luminaires blend into the existing concrete sill to which they
are mounted. The constant rhythm of the uplights draws upon
the museum’s historical relevance, while the fins disrupt the
monotonous façade and mirror the classical columns on the
Nelson-Atkins Museum.
Feeding off the architects’ desire to create a low level concrete
berm wall in front of the Kimball wing, the method for generating a secondary lighting effect was born. Seeing a need to
apply a second layer of light to contrast the vertical emphasis,
the low wall, approximately 20 ft in front of the façade, allowed
a series of NEMA 4 x 3, 250 W ED18 floodlights to be hidden
from vehicular view. In order to ensure this second layer would
also act as a backdrop and a complement to the uplights, each
luminaire was fitted with glass color filters to match Rosco
#358-Rose Indigo gels. The low five percent transmission provides a subtle pale violet light that envelops the entire building
and underscores the vertical white accents. The blending of the
warm and cool light textures creates a subdued drama, well
suited to the close proximity of the major boulevard. With
street access so close, a lighting design predicated on overly
bright effects would have distracted vehicular traffic.
As a stark contrast to the Kimball building, the Spencer
design was an intentional understatement at night. A driveway,
parking lot and rigid formation of trees in front of the building
beckoned a different lighting approach. Instead of illuminating
the façade, the intent was to uplight the trees in a dramatic
38
LD+A/April 2001
5200K, 175 W metal halide source, to emphasize the greenery
and bring the perceived line of light closer to the street.
As a means to connect the parking lot to the entry, the architects created rock garden pods. Within each island of massive
stones, mini-bollards with 60 W xenon lamps and four optical
ports were precisely located within the center of the rock cluster to illuminate the sides of the massive stones and produce
interesting patterns on the ground.
Contemporary parking lot poles specified to blend in with a
predominant metal skin completed the Spencer side design.
The polarity in philosophies between the two facades was not
only to visually shorten the interlocking buildings, but to also
give each wing its own identity. Whereas the Kimball building
was treated very formally, the Spencer side was envisioned as
more casual.
Acting as a mediator between the two structures, the central glass cube gives visitors the only glimpse into the newly
constructed lobby. Originally designed as a glowing volume,
the vestibule combines CMH70/U/PAR30L/40 recessed
downlights clustered in a tight 4 ft grid in the ceiling with
incandescent based uplights. 75PAR30/H/NFL direct burials
with internal glare control are situated in the corners of the
vestibule to allow visitors an uninterrupted view into the
lobby. Highly reflective and transparent surfaces assist in the
projected image of a luminous box.
While many projects have distinct boundaries between interior and exterior spaces, the MRI’s transparent vestibule blurs
this distinction. In this case, the lobby’s lighting makes a direct
www.iesna.org
(opposite) With street access so close, the
exterior lighting needed to be unique. Overly
bright lighting would distract vehicular traffic,
so subtle, layered lighting effects were used.
With a neoclassical museum on axis across the
street, the right façade was treated in a gentle
rose purple wash. Wall-mounted 250 W
metal halide lamps in NEMA 3 x 4 floodlights
with custom-color filters generated the base layer.
With the left façade on axis to a park setting, the
approach focused on landscape illumination.
To enhance the vibrancy of foliage,
5000K metal halide uplights were used.

contribution to the exterior image and provides visual depth to
a façade physically located close to the street. A band of
Horizon Blue cold cathode is evident from the street, drawing
the eye deep into the reception space. The cold cathode cove
also lies directly above slanted, frosted glass panels implemented to visually separate the lobby from the corridor beyond.
A series of 32 W T8 85 CRI fluorescent asymmetric throw
signlighters nestled into a metal trough at the base of the panels gently backlight the frosted glass. The partition wall and
ceiling detail not only blends glass and drywall surfaces, but the
backlighted wall defines the lobby boundary from the corridor
while creating a theatrical backdrop for the reception desk. A
further refinement of low voltage festoon lamps built into the
reception desk face parallels the definitive horizontal cold cathode effect. Focusing on material enhancement, the lobby relies
upon a mixture of sources to best represent interior surfaces.
While 26 W triple tube compact fluorescent downlights provide ambient illumination, Q50MR16/C/NFL recessed
adjustable accent lights brighten the glass reception desk. An

allows this space to read as a central entrance to the exterior.
As a centerpiece of the renovation, a curved metal scrim wall,
measuring more than 100 ft long and 20 ft high, acts as a literal gateway to the new vestibule and lobby. As a figurative bridge
to the future, the semi-transparent perforated metal scrim
changes appearance from daytime to nighttime. As viewed during the day, the 3 ft thick double layer wall appears as a plain,
flat metal surface. At night, with a series of F48T12/SPX35/HO
asymmetric throw fluorescent signlighters mounted within the
interior shell, the wall changes to a luminous glass block surface; full of depth and texture.
Depending on the angle of a visitor’s approach to the wall,
the luminous metal takes on added properties of light as
applied by the rose-indigo floodlights or the parking lot lights
adjacent to the wall. It is the technique of internally illuminating the double layer wall that provides a direct connection to
the luminous vestibule and lobby.
To complicate the mounting of the fluorescent signlighters, a
portion of the wall stands within a pool of water, fed by a
trough originating at the glass vestibule. A secondary visual
connecting device is generated by edge-lighted and point
www.iesna.org
source fiber optics. A 150 W metal halide fiber optic illuminator remoted in the lobby feeds the 0.5 in. diameter fiber optic
run lining the water trough to the pool below. Point source fiber
optics recessed into the outside of the water trough illuminate
a small rock garden at the entry. Additional point sources within the pool reflect constantly changing color on the outside of
the metal wall. Opposite the water trough, low voltage stainless
steel recessed steplights within a massive granite block lead visitors to the luminous vestibule.
The asymmetrical lighting balance between the use of strong
architectural accents in the Kimball wing, and the use of less
formal landscape lighting in the Spencer wing is held together
by the prominence of the scrim wall and the vestibule beyond.
The intentional visual competition (or juxtaposition) between
buildings helps to draw one’s attention to the center of the complex, where the chaos generated by two distinct lighting styles
flows into the order of the luminous glass box entry. Each piece
of the lighting puzzle becomes a visual connector to the next,
where individual components strengthen the overall effect.
Together, all the concepts — landscape lighting, backlighting,
accent lighting and color — form a cohesive design with the
architecture, both old and new.
Only by experiencing the entire complex will a visitor understand the complexity of visual queues assembled for the MRI.

T
he project containing the Hollywood
Tower is known as “Heron City.” This, the
first of many projects under that brand
name, is located on the northeast edge of Madrid
in a booming town known as Las Rozas. The
demographics of this area are generally that of a
youth-oriented market: young families and a relative upscale spending capacity. Madrid and most
of Spain are experiencing an un-paralleled
growth, both in the economy and the population.
The process for developing a lighting and
audio scheme for this project began almost two
years ago in the architectural offices of Studio E
in Orlando. There, the initial graphics were
shown to the design team, Illuminating Concepts
(IC). The designer in charge, Chris Miles, delivered the express desires of the owner. At that
time, the scope of the project for IC was to develop an all-encompassing lighting and audio system that would bathe the consumers in a variety
of colored, changing light and immerse them in
what is generally considered “surround sound.”
The “mall” as Americans would call it would
not be designed as a mall. Instead it was to be a
400,000 sq ft, open-air “entertainment center.”
The English call this a “leisure center.” The first
challenge as a design team was to get on board
with British linguistics and syntax; a means of
communication I have grown to adopt and even
prefer. My staff has even taken to quoting
Shakespeare.
The true challenge of developing a lighting
scheme was that we really had no existing model
to extract principles from. The architectural
treatment takes its cue from the new Universal
Islands of Adventure (UIOA) and City Walk in
Orlando, a project that IC had the privilege of
working on. The best description I can give is
that of industrial new age high-tech with a sprinkling of mysticism and humor. However, UIOA
did not meet the level that the client wanted to
achieve. Additionally, the architectural scheme
had already been set and the project had started
construction. This fact also created a fundamental challenge: where to suitably place the lighting
and audio systems.
IC offered a number of solutions for the architectural challenges of concealing the entertainment systems. Most of them had to do with carving out positions in the architectural facades so as
to only make the nose of the lighting instruments

Ron Harwood, president of
Illuminating Concepts, discusses his
firm’s role in designing the Hollywood
Tower, a 90 ft tower that performs an
operator-free synchronized sound and
light show in Heron City, an

visible. We offered a scheme that bathed the audience and pedestrians in static color changing High End Systems EC-1s and
ES-1s. The presentation, held in the owner’s offices, included a
description of lighting the one- and two-story facades, as well as
the brick and tile pavers of the streets and plazas. We explained
how the systems would be controlled to run automatically.
At the end of the presentation, Gerald Ronson, the owner
and visionary of this endeavor looked up and simply said,
“Where’s the show?” Somewhat dumfounded, I respectfully
center is simply two plazas — one named Hollywood and one
named Fiesta — measuring nearly 150 ft in diameter, connected with a curved passage between them. The curved passage,
several hundred feet long was named “the Paseo,” and would
be similar to a typical European “high street” with restaurants,
bars and trendy shopping. This area would have the least
amount of lighting animation and sound FX as it tended to the
relaxed component of the entertainment philosophy.
The Fiesta Plaza, not shown in the pictorial, was intended
asked him to explain his idea of “show,” as the presented
scheme far exceeded any permanent lighting scheme in retail.
His reply, as I have now grown to expect, was brief and to the
point. He wanted a permanent, hands-free, sound and light
show that entertained the customers every half-hour — not a
few gobos spinning on the floor, and not just changing color on
the buildings. Ronson wanted fully synchronized sound and
light shows that played in the entire center.
If you “have a think” about it (in British vernacular), most
sound and light shows are equated to stage presentations that
obviously have featured performers. Who or what would be
our central focus? How would one conceal the instruments
required to produce such a show and finally, what kind of show
control devices could one use to guarantee a relatively failsafe,
hands-free system?
First, we had to get the architect and owner to agree to generally exposed instruments. Most of the moving lights would
need waterproof enclosures. The designers at IC proposed a
“speedrail” that sits atop, and longitudinally oriented to, the
building facades. We ultimately came to an agreement that the
“sense of show” about to happen at dark would be a branded
foretelling of the entertainment to come, instead of relatively
ugly and inactive theater luminaires doing nothing. We also
came to learn that the sight distances of the gear on the rooftops
came in scale with the center and looked quite good, as one
normally saw very little of the fixture housings and bodies.
We then recognized the two “icon” towers at each end of the
scheme as our central focus “performers.” The design of the
to be the more active of the two plazas. It actually has two
towers. The first tower is called the DJ tower and — as the
name implies — has a central DJ control system, which, by
touch-screen interface, allows the user to interrupt the normal sound and light shows and take over manual operation
of the moving lights and audio system. The second tower is
90 ft high and designed in a perforated metal spiral or helix,
which arrives at the peak to terminate in a mesh, inverted
cone. As this is the most active space, IC affixed a dozen flash
units and a number of vertically oriented EC-1s to wash animated light up the helix.
The Hollywood Tower is located adjacent to an AMC 24
Cinema on one side and mostly fast food establishments on the
other. It also measures 90 ft tall and has a diameter of nearly 30
ft. Given that it was designed and engineered prior to IC’s directive to produce an animated show design, the challenge to
make this tower a show feature was the greatest that IC’s
designers faced.
The tower has a perforated metal cladding for its exterior and
an “inner egg” of metal framework and clear plastic panels. As
an architectural lighting opportunity, we looked at creating several illusions of space and volume.
First, the most obvious design opportunity was to separate
the inner egg and outer surface by lighting inside the outer skin
with white PAR 64s pointing up and down, attached to a new
speedrail that needed to be welded to the inside of the previously designed tubular structure. These would have chase
capability, along with a variety of other effects that could be

the parameters of large-scaled architectural features and themes to
produce a space that conveys the excitement, glamour and intense
theatrical experience of a Hollywood film opening. This view, from the
corridor linking the two major plazas together, expresses the scale of the
project. (right) Intelligent lights and dimmed PARS timed to music

generated during programming. Second, we washed the outer
skin of the inner egg to make it glow within the structure in a
pearlescent fashion.
Third, and perhaps most interesting, we made the inner egg
a “solid” element by filling it with fog and mounting EC-1 color
wash units within. Fourth, we needed this tower as a lighting
position to create an illuminated and sometimes animated
street scene. For that purpose, we mounted four, weatherproofenclosed, High End Systems Cyberlights at the very top of the
Tower, which have the capability of hitting many points in the
plaza. Finally, from other positions in the plaza, IC used High
End Systems Studio Spots in Ecodomes to illuminate the front
facing façade of the Tower.
Then came the animated fountain in the heart of the plaza.
As part of IC’s show design goals, we recommended to the
owner that he consider an animated and performing water display with the ability to be programmed to sound. It comes in a
package that includes a dichroic lighting system.
We offered to take the show design concept to an even higher level by taking the “machine code” of the water feature control system and synchronizing it to our lighting programming.
The result, we predicted, would be an “immersion experience”
unlike that achieved outside of the theme park industry.

LD+A/April 2001
Fortunately for us, a new team member appeared from
Heron in the person of Nicole Ronson. Ronson, an experienced media producer and founder of Nicron Productions in
the U.K. had recently come on board as the entertainment
director for Heron. If there was any doubt that this new concept would fail to produce an even more enhanced experience, she calmed any fears.
Once all of the concepts were approved, the IC team, led by
Ronson, embarked on a music search that compiled more than
500 CD’s of music that ranged in genre from World to Motown.
Music was the most important factor in the overall lighting
design; as this was to be a light show first and an “enhanced
ambient scheme” second. I applaud my able son Benjamin for
the initial research, sound editing, sound manipulation and
compilation. His knowledge of world music and popular music
set us on a course that proved quite successful.
Adding music concepts at a furious pace were Michael
Shulman and Nicole Ronson. Once the team had narrowed the
selections to around 100, we finalized our “light shots,” overall
lighting placement and mounting details.
All the while, Kenneth Klemmer, the IC design director, was
designing and supervising the balance of the architectural lighting scheme and coordinating the lighting of the owner’s megagraphics package. Heron’s David Fraser in conjunction with
Lara Farnum and Mark Goldstein of Fitch led the mega-graphics design team. Scott Stephens, Michael Shulman and Larry
Shirmer of IC were simultaneously developing one of the most
sophisticated show control packages ever to be built.
The system begins with the ability to completely monitor the
controls and functions as well as the ability to upload new program schedules. It is almost entirely redundant with failsafe
back-ups for audio and lighting. The system is the “show start”
and “show off” for the water systems as well. This became a
www.iesna.org
requirement in order to synchronize sound and light shows
with sound light and water shows, as both are distinct and play
at alternate times. Manual overrides are accomplished by touch
screen with password protection.
Because of the vast distances signals had to travel, and the
need for two-way communication between the lighting, audio
and water systems, IC used a Strand fiber optic network with
nodes in each of the towers. In all, four universes of DMX are
almost entirely filled. The main lighting controller is a High
End Systems Whole Hog II rack mount that contains all of the
lighting programs. It responds to a variety of signal protocols
required to enable monitoring and “if then” functions which
are polling constantly throughout the network. Nothing about
any of the system integration and automation was “off the
shelf;” all of the interaction between devices was a matter of
code programming.
The “enhanced ambient” design is, in a sense, what remains
between water shows and light shows. Not much time exists between the “big shows,” and it is important not to let the audience
cool down inbetween. The team designed slow moving color
washes and changing gobos to entertain children who bore easily. Star gobos that move slowly around the plazas have a mystical attraction for the kids, who chase after them endlessly.
Part of the enhanced ambient look of the space is to provide
good quality light and colored light for street performers, who
— from time to time — roam the plazas, gathering an audience, returning to a space that is lighted for their purpose.
Finally, the on-site show programming of the towers, and all
of the other special features, took place during the most desperately cold and rainy days (and nights) of December through
March. The IC team, led by Michael Shulman, of Chas Herington and Joe Allegro (lighting programming), Scott Stephens
(show control and network), Larry Shirmer (audio and show
control), Sheila Fitchett (special projects coordinator), Ken
Klemmer and John Bartley (focus and DMX) embarked on a
frozen journey of months of programming after dark.
The result was 15 sound and light shows, 25 water shows
supported by sound and light and a series of enhanced ambient effects between them.
The final test of this exercise was the visitors. In a professionally taken marketing poll, the consumers rated the shows the
number two reason for coming to the center. The number one
reason was to see a movie. Statistically speaking, this means perhaps one million people would come just to see the shows.

For the design team, this was a lesson in how exterior lighting can go way beyond
its normal role.
Mark Major
Our approach to exterior lighting has always been to look at the “big scale.” Our
backgrounds in architecture provide us with a good grounding in urban design and
details the firm’s work. planning and the necessary confidence to grab a “city size” problem and deal with it.

LD+A/April 2001

Our philosophy is based on the principle that the external
environment is effectively a blank canvass after dark, and the
way we choose to light it will affect character, meaning and
interpretation. In turn, this will inform such factors as safety,
economic success, sustainability, etc.
When we were asked to illuminate the Millennium Dome,
we quickly prepared a “Lighting Masterplan.” This was done in
close collaboration with the architects and the show lighting
designer (Patrick Woodroffe). Our remit also included the
main architectural lighting to the interior. This meant all the
internal elements likely to affect the external image were also
within our brief.
The building itself (all 800,000 sq ft of it) sat centrally on the
site. To the west, the scheme included the entrance, ticket kiosks
and queuing zone. A network of large tensile canopies covered
this area linking facilities such as shops, restaurants, etc.
To the East was a 250 ft long bridge and pontoon for those
coming by river traffic. The VIP and service areas were to the
west.
The whole site was wrapped by a riverside walk. Artwork by
leading British artists such as Anthony Gormley, Anish Kapoor
and Richard Wilson were placed throughout the site.
The highlight, of course, was the Meridian Line itself. This
extended from the Royal Observatory at Greenwich over the
river and across one corner of the site. This is the line where
time begins and ends, and this theme underscored much of the
main concept for the whole architectural scheme.
Given the brief and the setting, the approach could be
therefore kept simple. It should also be said that the relatively tight budget dictated that there was little room for extravagant detailing.
The scheme
Given the client’s requirement for the building to function
safely, be easy to maintain, minimize energy use and provide
“fitness for purpose” at all times, it was agreed that the lighting
should be designed at a level one would generally expect to
www.iesna.org

2000
find within a permanent building and landscape scheme. This
also supported the idea that the building and key structures
would remain as “legacy items” to be re-used after 2001.
While working with Patrick Woodroffe and the production
team, we came up with suggestions of how architectural lighting could be used dynamically through interfacing the architectural and show lighting control systems.
These elements were carefully selected for their effect when
viewed from a distance, especially from the neighbouring towers of Canary Wharf, and from aircraft coming into Heathrow
and City Airport.
In designing the scheme, we went for a policy of providing
no amenity lighting, with the exception being along the
Riverside Walk. This path was lighted with 4 m high column
mounted lanterns using 70 W CDM lamps. These were selected to assure continuity of detail with the neighbouring site
The concept was then to light all the architectural and landscape elements and provide no other amenity lighting. This
achieved many goals.
First, it provided a site which was clearly legible at night,
thereby assisting with general orientation as well as creating the
image. Second, it provided a large amount of reflected light,
which created sufficient ambience to fulfil basic requirements
for visual acuity and safety. Third, by concentrating light mainly on vertical objects rather than on the horizontal plane, it
helped define the visual boundaries.
The yellow masts were lighted using 250 W metal halide narrow angle projectors set inside the structure. They were carefully louvered to meet the approval of the Civil Aviation
Authority. At the base of each mast was a huge concrete block
anchoring the main structural cables. Bulkheads with red filters
using compact fluorescent lamps were fixed to these making a
deliberate reference back to the red LED aviation lights at the
top of the mast.
Knowing that the internal fabric of the dome would glow
from within meant that the decision to uplight the external
overhangs was made early. This was done with approximately.

300 adjustable direct burial uplighters, using 70 W
CDM-T lamps. These not only washed the fabric
above, but also highlighted the fine steel structure
supporting the translucent cladding. The larger
overhangs were illuminated using wide angle floodlights employing 150 W CDM-TD lamps.
The 12 large plant cylinders were the “engine rooms” of the
scheme containing the ventilation, electrical switch gear, cisterns, etc. The open framework of these massive pods was covered in vertical louvers. It was decided to light these internally
with a bold, red light using 500 W tungsten-halogen floodlights fitted with dichroic filters, which were specified to allow
for total flexibility of control. The floodlights were circuited by
level, and each was separately addressed by cylinder to allow
46
LD+A/April 2001
the show system to create chases and effects. The legs and mesh
covered maintenance stair were also lighted to help connect the
cylinders back to the ground and provide safe lighting in the
adjacent area.
It was decided that the canopies that traversed the site would
be uplighted. The larger ones were from asymmetric floodlights
using 70 W CDM-T lamps bracketed off the support columns.
The smaller canopies were lighted from the ground using 35 W
CDM direct burials.
The ticket kiosks were internally illuminated
using two colors of cold cathode: blue at the base
and white at the top. When the kiosk was in use,
both lamps would be on together with local task
lighting to the desk. When closed, only the blue
lamps would be on. Other merchandise kiosks were
simply lighted with a variety of tungsten-halogen
uplighting and spotlighting.
The main piazza was illuminated from the indirect light reflected off the canopies surrounding it.
Across the area lay a grid of color change luminaires,
which also contained a xenon strobe allowing the
show designers to create different effects to be seen
from the air.
Various vertical landscape features bounded the
site. The Hanging Gardens, which surrounded a
large vent shaft from the underground system, was
clad in falling plants, which were backlighted with
linear fluorescent. The Living Wall, which formed
the western boundary to the site, was lighted using
a mix of low voltage tungsten-halogen and compact
fluorescent.
There were two pavilions on the site in the form
of The Rotunda, a venue, and the Greenwich
Pavilion, an exhibition and restaurant facility. Both
of these were large structures in their own right, but
in the interests of maintaining the hierarchy across
the site, all the external presence came from the
internal lighting glowing out.
The canting brow bridge and pontoon were the
major gateways from the river. The large, arched
steel structure was painted blue and so it was lighted in a deep shade of that color to saturate it. The
www.iesna.org
canopy that then ran along its length was uplighted from the
ground from a specially designed color change luminaire,
which used a red, green and two blue dichroic filtered MR16s
to create different color mixes.
The architectural control system was employed to mix the
various channels of lighting, which were circuited in groups to
create a slowly rippling color change, which almost seemed to
move with the water. The pontoon itself employed white
canopy lighting to provide safe but discrete functional lighting
for disembarkation of the boats.
The final feature to be considered was the one that, in many
ways, was central to the story of the Millennium Dome: the
lighting of the Meridian Line. One of the reasons the
Greenwich peninsular was chosen as a site for the project was
its relation to Greenwich and the Meridian — the line that symbolizes “where time begins.” This was formed with red LED
strip set flush into the ground and mirrored at the boundary to
create an infinite line.
The Presentation
Despite the fact that New Years Eve 2000 saw an incredible
celebration to mark the new Millennium, the project was
dogged throughout the year by negative publicity, management
scandals and other issues that diverted from the fact that more
than six million people enjoyed “One Amazing Day.”
For those that were there after dark, the exterior lighting
played a positive role in setting the scene for what one would
enjoy inside. For millions more who flew over, drove past or
even witnessed on television the splendor of the Millennium
Dome, by nightfall, the architectural lighting became one of the
positive stories of that year.
One year later, the Dome has fallen dark. Further political
scandal surrounds its future. The internal exhibition and show,
the internal lighting and other features have been ripped out.
Some, regardless of the colossal waste of resources it would represent, have even called for the building to be ripped down.
Despite all this — Richard Rogers Partnership’s great building, together with its architectural lighting scheme, at this time
remain intact — waiting to support new life for the building.

hen the Ohio Turnpike was designed in the mid1950s, 16 service plazas were included. The service
plaza concept had originated earlier on the
Pennsylvania Turnpike, and consisted of gas pumps and auto
service facilities with an adjacent service building housing a
family-style restaurant, restrooms, a small sundries shop, maps,
and some travel information. Much like the gas stations and
motels ubiquitous in America after World War II, this restaurant was a low, family-scaled structure with residential imagery
and materials-ranch styling, gabled roof, Pennsylvania limestone facade, and white wood trim. The design intended to
offer the comforts of home for mobile families on the road.
Another model for the service plaza was America’s favorite
1950s restaurant, Howard Johnson’s. As noted by Phil
Patton, “In the 1950s, variety in food on the turnpike meant
28 flavors of ice cream to follow the wrinkled frankfurters in
paperboard trays.”
The Ohio Turnpike service plazas, like their Pennsylvania
ancestors, were designed in pairs, one servicing westbound traffic and the other servicing vehicles traveling eastbound. Their

In 1994, the Ohio Turnpike Commission (OTC) embarked
on a long-range plan to improve and widen the roadway and all
turnpike facilities. This plan and the study it generated identified the service plazas as antiquated and no longer serviceable.
The poor condition of the plazas was matched by their inability to accommodate the increasing volume of vehicular traffic.
Moreover, the plazas were not providing the variety and technologies of service required by the vast array of 21st century
travelers, including business people, travel groups, and truckers, as well as families.
The cost of remodeling the old plazas versus constructing
new ones was comparable, due to the extent of site work
required with either option. After conducting a patron research
study, the OTC opted to build new structures and to strategize
their design for maximum functionality and flexibility, to last
another 40-plus years.
Because of their proven success in designing facilities for business, commerce and technology, as well
as in multi-use site planning, GSI Architects, Inc.
was selected as designers of the Ohio Turnpike travel centers.
The program was a complete metamorphosis of
the service plaza into a state-of-the-art travel center,
with services and amenities geared towards seasonally-fluctuating volume, need, flexibility and patron
choice. The new concept of “travel center” was not
just a rest stop, but a functionally targeted destination spot with services normally expected from a
regional shopping mall or airport.
The patron survey conducted by the OTC, as well
as the Commission’s facility study, resulted in a program that included the following: varied food service
operations, operating much like a shopping mall
food court with common seating; a generously sized,
informative lobby; larger, well-marked restroom
facilities and a family restroom; a business center
with fax, copy machine, and ATM; telephone stations; a vending machine and game area; a travel
shop and flagship gift shop; and a separate area for
truckers including a “living room” with TV, laundry
room and showers.
Visitor services included continually updated
lodging availability, a meal or snack from a variety
of vendors, including fast-food and sit-down-style
establishments; state-of-the-art, pristine restrooms, and amenities designed for the busy person
on the go.
The complex was designed as a “transportation node” — a
hub including parking, fueling, vehicular service and traveler
services.
“The buildings have a strong sense of eaves,” says Celso
Gilberti, principal, GSI Architects, Inc. GSI’s prairie style is also
modeled after its contemporary equivalents: “the better shopping airports” of the East and Midwest. The centers also possess a look of sleek elegance, which is given visibility in form
and detail in the columns of the food court. Faced inside and
outside with bricks of a similar pattern and hue, the columns
appear to glide effortlessly through the perimeter windows as
they “clock” the volume’s circumference.
Vertical elements give the travel centers a distinctive identity
from the road. Each travel center is “announced” by a 75 ft tall
vertical tower at its outermost extension. These “Portals of
Ohio” provide the requisite visual clues for motorists, functioning in the same way as the high hotel, fuel and food service
signs adjacent to interstates.
Corresponding features and details reinforce the travel center stop as an experience. These include the smaller, 35 ft tow-
ers at the patron parking entrance of the center; an outdoor
trellis which can accommodate a farmer’s market, small vendor
kiosks, and artist/craftsman demonstrations, promoting “see
Ohio” events; and the food court itself, where floodlighting and
accent lighting transform it into a glowing orb by night.
Dynamic, directional look
Sleek and horizontal, the travel centers were inspired by the
Wrightian Prairie Style, present in northern Ohio in a number
of houses designed by Frank Lloyd Wright. (One of these houses is in Oberlin, in the immediate vicinity of the turnpike.)

glowing food court with space for five food vendors and an
independent restaurant. It is roofed with a shallow copper
dome spanning a diameter of 80 ft. The space accommodates
feature and seasonal displays at its center, as well as generously spaced seating with tables of varying configurations. As one
moves from the center to the periphery of the food court, partition “arcs” define an inner circle and set off four smaller dining areas, each marked by dual light towers.
The second room, linked to the food court by a vestibule, is
the service area and lobby. This space houses restroom and
business facilities, a kiosk-style travel/gift shop, vending area,
game room and telephones, and links to the separate trucker
area. The “destination wall,” a major design element and the
arc of a huge circle, can accommodate seasonal and regional
displays. At the convergence of the visual axes established by
the four lobby entrances (the two “front doors,” the trucker
entrance and the food court vestibule) is the information
booth. Its curved, stepped countertop provides ample space for
opening and marking maps or browsing through brochures.
Designed into the booth are brochure racks. Each travel center’s
brochures feature local and regional attractions.
State-of-the-art lighting
The lighting design for the new service area plazas for the
Ohio Turnpike respond to the owner’s mandate for all elements
of the design: The new facilities had to be durable, efficient and
easily maintained. Further, lighting, as in all public facilities,
plays a role in safety and sense of security for Turnpike patrons.
The lighting design is a natural evolution of the architectural
massing and articulation.
Natural lighting and artificial lighting complement each
other, especially in the large lobby and food court spaces of
the building. A long, curving brick wall topped by a continuous band of clerestory windows forms the entrance lobby to
the facility, connecting auto parking areas and the auto fueling areas. Natural light animates the space during the day. At
night, the building glows from within and the roof, with its
long extended overhangs, appears to float structurally unsupported above the wall. The lobby space is designed with fluorescent downlights for general lighting, track lighting by Halo
using 50 W PAR 20 lamps for display wall areas, and an array
of Louis Poulsen pendant-mounted fluorescent fixtures above
the information desk. Here, as in the rest of the building, light
fixtures are specified to provide architectural interest as well
as specific lighting tasks.
The lobby features an electronic information center, with
50

Inner décor provides ‘mood’
wall-mounted fiber optic signage delineating the weather,
news, construction, and traffic delay/redirection information.
In the food court, a continuous band of punched windows
below the domed roof brings splashes of natural light into
this space, and expands on the architectural language of floating roof planes. At floor level, patrons have a view out to the
exterior dining areas and the highway through large windows
separated by a series of brick piers. The dome is lighted with
a ring of adjustable asymmetric indirect metal halide fixtures
by Lam, mounted just below the clerestory of punched windows. These fixtures evenly wash the 80 ft wide and 24 ft
high domed space, while providing easy access to the fixtures
for maintenance.
Two additional levels of artificial lighting reduce the scale
of the space and give it some intimacy. Eight pairs of metal
halide Louis Poulsen luminaires on individual 12 ft poles
mounted on the 4.5 ft high partitions, which zone the food
court space for seating, queuing, and condiments, animate
the large space at one scale. They have an old-time streetlight
feel, a subtly nostalgic effect that recalls the best designs of
today’s malls. Fluorescent Louis Poulsen sconces, one on each
pier, animate the space on a more human scale. These luminaires, with their horizontal, Saturn-like rings, expand on the
architectural language of horizontal lines and floating roof
planes. The fixtures are space-definers, as with the polemounted fixtures, and are accents for highlighting architectural features, as with the sconces.
The gift shop has all of the features of high-end specialty
stores: high-intensity, track-mounted luminaires, recessed
lighting, glass display walls, and sparkling display panels.
Shielded, cornice-mounted lighting along the circumference
gives the shop a glowing, almost weightless quality. It
becomes a destination point responding to the destination
wall.
In the more utilitarian spaces, fluorescent sources are typical. However, the main public restrooms, combine an artful
use of an indirect linear fixture mounted above the mirrors
which evenly illuminates a half barrel vaulted ceiling. A
recessed cove on the other side of these rooms completes the
lighting scheme of evenly washed surfaces and no visible
light sources.

The inner “landscape” of the food court is equally appealing and memorable. Beneath the glowing dome and perimeter walls are the various concessionaires whose establishments are marked with the trademark “Wendy’s” or “Panera
Bread” in warm, glowing neon. The signature decor of the sitdown restaurant provides additional warmth and coziness.
The floor tile scheme tracks the food court/lobby axis in appetizing colors: mocha, latte, buff, ivory and a chocolatey hue
that can best be described as “Oreo shake.” The ivory hue
continues in the ivory-colored bricks, which define the
perimeter seating elevation. Above this level, the brick color
changes to traditional terracotta.
The walls of the travel center are faced in a palette of
orange-red or reddish burgundy brick, cut in a small, Roman
pattern that gives texture and visual interest. (The orange and
burgundy schemes alternate from one turnpike center to the
next, in a scheme that unifies the 16 centers across the state.)
Small landscaped areas provide pet walking facilities, line
entrance ways and screen service areas from view. The main
entrance ramp is lined with trees and wildflowers to provide
an inviting, parklike quality. The site is lined with trees and the
landscaped camping area is well screened from service areas
and ramps.
New facilities on the New York State Thruway — larger
plazas with more services and more varied food — reflect the
Ohio influence. Representatives of other turnpikes continue to
visit Ohio’s travel centers.
However, the full effect can be experienced only in the driving. There’s nothing like the jolt when, after reading the green
sign that says “Service plaza, one mile, travel information,” one
pulls into a facility which makes that 50-year-old phrase not
only a promise, but an understatement. Like the decades-old
slogan, “the pause that refreshes,” the turnpike promise of
immediate, informative service has been newly, refreshingly,
and delightfully reinvented. At the travel center mileposts, it
becomes a reality.

NOT IN
MY DARK YARD
Light trespass has become an industry buzzword over
the past few years. But as Edward Kramer explains,
simply eliminating light trespass doesn’t solve the whole
problem. You also have to address light pollution.
I
n recent years, the issue of light trespass has become a hotly debated
topic. Although this article specifically
addresses roadway and street lighting
installations, the same principles and
design challenges apply to lighting
design tasks with shopping centers and
office building parking lots. Today, while
citizens are requiring increased lighting
for safety and security, it is up to lighting
specifiers and manufacturers to make
certain that light control is added to the
design specifications.
As lighting, civil, municipal or roadway engineers, specifiers design lighting
systems as they always have done in the
past. Designs meet the seven minimum fc
requirements and stringent max/min and
aver/min ratio requirements imposed.
Why then, do design specifiers often get
more complaints today? It is because a
new design element must be added to
lighting design specifications: “Environmentally-friendly.” Not only must required lighting levels be met, but it must
be done in a manner that eliminates
“light pollution” and “light trespass.”
Engineers know what effective lighting is. They know how to clearly list
design criteria, and they know the right
way to design a project. They also know
that new products and technologies are
emerging on a regular basis. That is why
our designs of yesterday may no longer
be what’s best for today’s society and
today’s needs. Modern technology, manufacturing capabilities and an enhanced
52
LD+A/April 2001
ability to better understand how to control and analyze light distribution, have
changed the way engineers design and
evaluate roadway and outdoor lighting
designs.
Let’s take a closer look at these new
design considerations. As a society, we
want and demand lighted highways both
for safety and security. But as property
owners, we don’t want any stray light on
our property. There are two terms that
are generally used to describe these concerns: “Light Trespass” and “Light
Pollution.”
While these terms are often used interchangeably, they actually describe two
distinctly different phenomenon, often
caused by the same street, roadway or
area light.
“Light Trespass” is the actual light that
falls off the “right of way.” This can be
measured and quantified. In fact, many
professional lighting designers have
actually been obliged to go out at night
and take measurements of the light that
is actually falling off the right-of-way and
onto a concerned citizen’s property.
Often the measurements taken indicate that the offending light is at a level
less than moonlight! We take our findings back, write our report, and may
conclude that the complaint is groundless. We think we are vindicated; we did
our job. The public just doesn’t understand. They don’t know the differences
between a lumen and a lemon. We finish
our report, document our findings, and
secretly pray that the problem will go
away. Boy, are we wrong.
We addressed “Light Trespass,” but
not “Light Pollution” — the perception
created by source brightness, the actual
brightness of the luminaire — brightness
that, in some cases, can be miles away.
To make the problem go away, we seek
a quick, inexpensive solution to what is
really a complex problem. Our “easy”
answer is that old standby, the houseside shield. It is an afterthought solution;
a shortsighted luminaire design. This
solution hopes to cure a poorly designed
light fixture installation by adding a
maintenance problem, a large sheet of
metal fastened (often inadequately) to an
already installed fixture.
It is about time we bite the bullet and
take a serious look at our roadway lighting designs. Just because we designed a
project one way 5, 10 or 20 years ago,
does not mean that design is best for
today. As an analogy, take a look at automobile designs of today. The evolution of
the automobile over the past 10-20 years
has been phenomenal. Improved safety,
convenience, comfort and economy are
only a few of the benefits resulting from
this evolution. Shouldn’t our lighting
designs reflect similar technological
advancements?
Today, we have available to us roadway
lighting fixtures designed with integral
internal louvers and shielding to control
stray light. These luminaires are
designed for the exacting task of roadway lighting with optical systems that set
new standards for light control, and recognize the required economics of installation and maintenance.
Some communities have adopted
“Dark Sky” legislation and several manufacturers have begun marketing products that supposedly address this emotional outcry.
But does “Dark Sky” solve our problem? Is “Dark Sky” actually “Dark
Bedroom” or “Dark Front Yard?” The
concept of “Dark Sky” implies that useless light is blocked from shining directly into the sky. In itself, it does not even
suggest “Dark Bedroom” or “Dark Front
www.iesna.org
(From left to right) (top row) 1: The highmast fixture is a commonly used, economical solution for interchange and roadway lighting. This type of lighting
system has the lowest operating costs, when used with optional internal motor lowering devices. 2: The house-side shield is a piece of sheet metal that is
fastened to the fixture housing. Actual cutoff is usually about 85 degrees, and is limited only to one side. 3: The “dark sky” type of fixtures that seem to
have gained acceptance as a partial solution are, at best, a compromise. These fixtures cut off all light at and above 90 degrees. The fixture does not address
light trespass and, most importantly, light pollution. 4. The 80 degree shield offers total cut-off above 80 degrees from the vertical, with 360 degree radial
control. Light above 80 degrees never reaches the ground, but is considered to be the most objectionable source of direct glare and fixture brightness.
(bottom row) 5: 45 and 75 degree internal louvers give the designer tools that economically optimize fixture placement and reduce maintenance costs. This
is considered the most efficient method to minimize light pollution and light trespass. 6: The most economical solution and aesthetically pleasing alternative to the common cobrahead or off-set fixture for roadway lighting is the median master style. All internal shielding options are available. 7: The off-set
fixture is a contemporary version of the cobrahead. It provides good light distribution on the roadway, but with the highest glare and light pollution of all
roadway fixtures in use today. 8. The cobrahead, like highmast and off-set fixtures, once had prismatic glass lenses. These lenses create a source brightness
visible from distances as far as several miles away. The visibility of these light sources violates the so-called “dark sky” philosophies, and generally creates
light spill problems. There are now better options.
Yard.” The term means that an attempt is
being made to reduce the amount of
light going into the sky, and that is all.
A common offender of “Dark Sky” and
“Dark Bedroom” are the highmast installations used on highways, interchanges,
storage yards and major parking lots.
Some communities have succeeded in
eliminating the use of this type of lighting
because of past problems and a misconception of what is causing light trespass
and light pollution. Installations where
luminaire glare and brightness are objectionable leave a bad taste in the mouths of
a community. It is the task of engineers
and designers to educate themselves and
the community, so they can specify an
outdoor lighting system that meets all the
necessary specifications.
www.iesna.org
As lighting designers, we need to
make a thorough analysis of the optical
systems that we specify or approve. We
know, but may have forgotten, that
reflector designs that yield peak candlepower in the range of 65-72 degrees yield
the most economical roadway/outdoor
layouts. We also know that light above
80 degrees from vertical never reaches
the ground. Additionally, we know that
light above 80 degrees is the light that
causes direct glare and generates the
most number of complaints. All outdoor
lighting calculations need to include a
thorough review of the candlepower distribution of the luminaire selected. A
determination must be made about the
amount of light generated above the
peak candlepower of the fixture.
In conclusion, it is my hope that
lighting engineers and designers will
use the tools and the newest types of
outdoor area lighting luminaires at their
disposal, to develop what will truly be
the most effective and most economical
lighting installations, taking into
account design criteria, both specifically stated and implied.

FULL CUTOFF
LIGHTING:
THE BENEFITS
Although the definitions for cutoff lighting
have remained virtually unchanged for nearly
30 years, a new classification — full cutoff —
has been introduced. Douglas Paulin details
the finer points of this new terminology.
T
he term “Cutoff” first entered the
lighting vocabulary in 1937, as a
way to describe a “shielding reflector” for
streetlighting. It has also been used to
describe the angle of cutoff in recessed
luminaires. For many years, it signified
sharp glare control, but was not precisely quantified.
In 1972, the Roadway Lighting Committee Recommended Practice RP-8
defined “Cutoff Distribution” and “Semicutoff Distribution” with restriction on
light intensities at vertical angles of 80
degrees and 90 degrees above nadir. This
was the first time outdoor luminaires
were affected by uplight control in an
IESNA published document. The
descriptions are:
Cutoff: A luminaire light distribution
where the candela per 1000 lamp
lumens does not numerically exceed 25
(2.5 percent) at an angle of 90 degrees
above nadir, and 100 (10 percent) at a
vertical angle of 80 degrees above nadir.
This applies to all lateral angles around
the luminaire.
Semicutoff: A luminaire light distribution
where the candela per 1000 lamp
lumens does not numerically exceed 50
(five percent) at an angle of 90 degrees
above nadir, and 200 (20 percent) at a
vertical angle of 80 degrees above nadir.
This applies to all lateral angles around
the luminaire.
Noncutoff: A luminaire light distribution
where there is no candela limitation in
the zone above maximum candela.
Although the wording has changed

slightly since 1972, these definitions of
uplight control have not changed in any
material way. A cutoff luminaire in 1972
is still a cutoff luminaire today. However,
there are practical subtleties that need to
be explained before we can fully appreciate the differences between these three,
and to understand the new classification
of Full Cutoff.
A luminaire with a Cutoff classification can (and often does) have some
light above 90 degrees. The definition
of Cutoff says nothing about amounts
of light above 90 degrees, but it is generally agreed that the light should be no
more than the value at 90 degrees, and
should be decreasing as the angle
increases. In fact, there could be some
measurable light emitted at 180

else
degrees (Zenith). Uplight Control is
what these definitions describe. Not
absolute values, either, since the candela intensity is a proportion of the
lumen package of the lamp.
Another generalization that can be
made about a cutoff luminaire is that it is
flirting with the limits of the classification at 80 degrees, not at 90 degrees, and
this will usually occur in the horizontal
plane of the “MAX,” or in simple terms,
the main beam.
A luminaire with a Semicutoff classification can be something that “just

that the “beam” is perpendicular to the lens.
missed” being cutoff, but the manufacturer determined that the performance
as measured on the work surfaces was
more important than achieving Cutoff.
This is a trade-off involving glare-control
vs spacing-to-mounting height, and it is
not uncommon in the late 1990s. Some
of the most popular parking lot luminaires are actually semicutoff, when the
actual photometric report is viewed. It
also follows the earlier discussion on
light above 90 degrees that a luminaire
classified as semicutoff produces even
more light above 90 degrees than a cutoff luminaire is allowed.
A luminaire with a Noncutoff classification can also be something that “just
missed” being Semicutoff, or…a “glarebomb” that puts equal amounts of light
into the heavens as on the ground.
One last issue to understand before
leaving the Cutoff and Semicutoff classi-

fications: “Sagged glass” or any formed
lens which drops down below the bottom of the luminaire housing. The presence of a “non-flat” lens does not mean
the luminaire is not Cutoff. Sagged glass
is a good bet that the luminaire is not
Full Cutoff. It should raise suspicions
about a Cutoff classification, but it is possible to produce a luminaire with a
sagged lens, drop lens or even drop prismatic lens well within the limits of the
Cutoff classification.
At this point, we can establish a definition for the Full Cutoff classification: A
luminaire light distribution where zero
candela intensity occurs at an angle of 90
degrees above nadir, and at all greater
angles from nadir.
Additionally, the candela per 1000
lamp lumens does not exceed 100 (10
percent) at a vertical angle of 80 degrees
above nadir. This applies to all lateral
angles around the luminaire.
This term is found in print in RP-33
(Exterior Environments), the Ninth Edition of the IESNA Handbook and recently
in RP-8 (Roadway), which is the first time
it is an ANSI-approved document. Full
Cutoff is the most extreme classification
for uplight control. It allows no light
above 90 degrees, and in fact not one candela at 90 degrees. Now, just below 90
degrees? Of course, there will be light just
below 90 degrees. The closest angle a
photometer will probably report on is
87.5 degrees, although 85 degrees would
be more customary. It is difficult to conceive of a luminaire being classified Full
Cutoff if it has anything but a flat lens
which is parallel to the ground.
The other criterion Full Cutoff regulates is at the 80 degree angle, which is
identical to the Cutoff classification.
There is no guarantee that glare experienced in the parking area or roadway
will be better with a Full Cutoff luminaire than with a Cutoff luminaire. You
must obtain the photometric report to
determine real differences.
One final issue on Cutoff classifications: they are only viable if the luminaire is not uptilted. All Cutoff classifications are null and void if the luminaire is
installed with an uptilt.
• A Full Cutoff luminaire is effectively a
Cutoff luminaire if it is tilted up but one
degree.
• Many Cutoff luminaires will actually
give you a Semicutoff distribution (or
Noncutoff)
• Depending on the angle of uptilt, a Full
Cutoff luminaire can effectively give you
a Noncutoff distribution.
How does one guarantee the distribution described in the photometric report
is provided? Don’t allow them to be
mounted with an adjustable knuckle or
slipfitter. A rigid mounting arm with no
built-in uptilt and no adjustment feature
is the best guarantee. This will almost
certainly increase the number of poles
and luminaires, compared to products
that are uptilted. However, this should be
a trade-off that is in the hands of the
lighting professional, not anyone else.
