It has taken leaps and bounds in recent years, and opened up a world of opportunities. And when it comes to energy efficiency LED is well and truly at the top of its game – yet another argument in favor of the funding program for municipal building modernization projects as fathered by the Federal Ministry for Environment, Nature Conservation and Nuclear Safety (BMU). The program will fund the conversion of street lighting to LED to the tune of up to 40 percent of the total volume. You can find out more about what is involved in the initiative and how TRILUX can help in our planners’ question section (page 36). You can also read Markus Skeide’s opinion on this interesting topic on page 7, where he, among other things, advocates a holistic approach to such modernization projects. There are currently numerous initiatives aiming to refit or completely replace outdated lighting systems, especially in outdoor areas. In his article “Dynamic lighting in the public space”, Prof. Thomas Römhild sheds light on the use of LEDs in outdoor lighting systems to date and makes his own prognosis on the direction in which such applications could develop in the future (page 10). In our interview (page 18) we also ask three (lighting) experts about the experiences architects and lighting planners have had with energy-efficient lighting to date and the extent to which they believe OLEDs could be implemented in the architecture of tomorrow. Taking the examples of the Linsenberg daycare center in Kriftel designed by Schneider + Sommer Architekten (page 22) and the Fish Market in Bergen, Norway by Eder Biesel Arkitekter (page 30), we present some of our LED luminaires in use. The TRILUX Center of Competence close to HafenCity in Hamburg, which opened at the beginning of the year, has also been fitted with cutting-edge LED technology (page 40) – we’d be delighted if you stopped by to experience the high quality of our lighting products in person! I hope you enjoy reading the latest edition of 3lux:letters.

Photos: John Picat Light designer Gilbert Moity actively incorporated visitors to the Fête des Lumieres in December 2012 in Lyon into his light installation. On a space of 6 x 8 meters, four backlit polycarbonate walls, each five meters tall, were installed around the bronze statue of Louis XIV to form the “Magic Cube”. The energy needed to light the installation was produced by passers-by: For about five minutes they pedaled together on the 28 cycles arranged around the work of art. Depending on their performance and thus output, different colors and graphics appeared on the LED panels. Once the maximum energy was achieved, and the racing stretch finish reached, a firework display erupted – a welcome thank-you for the cyclists’ efforts. HISTORY Even though for almost 30 years the success of the 74 diffuser luminaire has rested on its plain design (top, other versions exist today, for example with a decorative square surround (bottom). The 74 series – quite a success story In 1984, we were approached by a client who made a special request of TRILUX: He needed a luminaire for the hallway, which not only gave off light concealed in the ceiling but would also emit light all around; in other words, he wanted something that looked like a small sun. TRILUX accepted the challenge and developed from the existing cylindrical luminaire 7411/32 the so-called 7402. The shape of the round lamp was retained but the diffuser was executed in a new, so-called “74 design” – a classic, sleek style which quickly led to the luminaire becoming a top seller. Today, the luminaire that is fondly referred to as Chinese hat or kneecap is still one of our best-selling products. Over the years, it was repeatedly revised and updated: The light’s strength was permanently improved, operating elements modernized, and not least of all, since early 2011 the popular 74 luminaire has also been available as an LED version. The model 7402 has two distinct LED systems, which can also be activated separately while retaining even illumination of the diffuser. This means that in addition to normal operation, it is also possible to select the night mode offering a 50 percent reduction in consumption. Despite the technical alternations it has undergone the plain design of the luminaire series has remained practically unchanged. True, a number of minor changes have been made to its appearance, but essentially the sleek version of the luminaire has always been the most popular and has ensured that even 30 years after that client voiced his special request, the success story is by no means over yet.

March 2013 www.kunst.celle.de Running until 31 March, the exhibition “Einleuchten” (Illumination) by Kunstmuseum Celle shows two very different perspectives on the topic of light. Artist duo Hartung and Trenz uses deliberately placed superimpositions to create multilayer light surfaces in typographic projections. The result: words written with white light, which affect the sentence depending on the visitor’s position. As shadow seems to make words fade constantly changing text constellations are produced. Austrian artist Waltraut Cooper has another perspective on light. The mathematics graduate applies her passion for numbers to colorful art installations, transferring the binary codes of symbols into vivid patterns. Photos: Detlef Hartung Photo: Torsten Volkmer The video projection “Holy Grail. Art and Mathematics” by Waltraut Cooper stands out for its startling clarity. Hartung und Trenz experiment with typography for their projections and have viewers become part of the work of art.

To mark Richard Wagner’s 200th birthday on 22 May, 2013, the Badisches Staatstheater in Karlsruhe is performing romantic opera Tannhäuser. It not only demands excellence from its singers. The secret star of this opera that is difficult to produce is light artist Rosalie’s illumination. Nine meter tall walls double as projection surface and boundaries on all three sides of the stage. The areas lit with moving lights and floodlights alter color almost imperceptibly, creating varying emotions, be it the erotic atmosphere on the Venusberg or the ice-cold mood of the Wartburgsaal. Simple props like dark hills or suspended elements complete the scenes. The opera runs until the end of June. The changing colors turn the stage into a new space without the need for major interventions.

It motivates and improves productivity. From 21 March to 31 May, the Museum für Energiegeschichte(n) in Hanover is showing “Light on! How light became electric.” With images, exhibits and experiments the organizers show the trials and tribulations humanity had to endure in order to have the luxury of a functioning light switch at its fingertips. They tell of Prometheus, from Greek mythology, who took fire away from the gods and brought it to the human world. Attention is also given to the evolution of the electric light-bulb, and a glimpse into the future shows the possible route electric lighting might take. This exciting exhibition is designed to shine some light on areas visitors are in the dark about. Photo: Historisches Museum Hannover Photo: Museum für Energiegeschichte(n) Licht an!

The family-run business TRILUX is offering business customers a peek behind the scenes, with the focus on the theme of office lighting. Indeed, working environments in particular require lighting solutions that adjust dynamically to the natural light conditions in the space. The seven-day trade fair will provide expert answers to questions surrounding dynamic lighting and light management systems. The highlight of the event will be “Light-Night”, when all visitors can come together and chat with the organizers in an enjoyable, informal setting.

But help is at hand in Finn Magee’s illuminated poster: In 2010 the Dublin-based product designer presented the “Flat Lights” concept, to which he has now added Flat Time – a retro alarm clock – and Flat Sound – a music box that can be used with an MP3 Player. For the poster in DIN A2 format he uses a 12 volt LED-technology, which permits him to light up certain areas of the object. The latter is printed with corresponding motifs, the lead runs up to the picture edge, and continues as a real lead. With his flat series Magee has created fun, but above all, space-saving home accessories. STATEMENT Dipl.-Ing. Markus Skeide Skeide Ingenieurbüro for intelligent electrical engineering, Rheinberg Many have now come to embrace the BMU’s ideas underpinning the “Climate Protection Initiative” and the opportunities it holds are clear. Nonetheless, many decision-makers in local authorities are squabbling over priorities and the financial viability of their own resources with their respective political committees (urban planning committees and councils). The subsidies from the BMU, being such a body itself, already represent an excellent basis for discussion. Though it must be said, taking advantage of financial backing is one thing, but it is the holistic consideration of the renovation projects that represents the real task at hand. The conditions for easing the delay in investment in modernizing interior and exterior lighting systems over the coming years are certainly good. The entire initiative is backed by some extremely attractive financing initiatives from the KfW banking group, whose effective interest rates make any credit facility offered by Kommunalkredit AG seem rather oldfashioned in comparison. Consequently, when it comes to the energy-efficient and sustainable modernization of lighting systems with a reasonable rate of return, the formula for success is: funding programs + a holistic consideration of the systems = substantial energy savings + high quality lighting (at least compliant with regulations) + a significant reduction of maintenance and service costs. This formula is easily applied to real scenarios. For the modernization of street lighting not only does this mean looking at the lighting in need of modernization, but at everything associated with it – from mast systems, supply systems and energy distribution to the installation of management systems, Below: In Dahlem in the Eifel region, 90 percent of the town’s old street lights were replaced with new LED lights. controlling and monitoring systems, to name but a few. This also offers up a range of options to reshape the respective cityscape and potentially to avoid so-called “dark spots” (areas in squares or around buildings that aren’t sufficiently lit and thus perceived as unsafe for pedestrians). The situation is just the same when it comes to interior lighting using LEDs. The choice of lighting manufacturer based on which products they offer and their capacity to fulfill a repeat order remains decisive. Here it would be advisable to turn to premium manufacturers who have been active on the market with certified products for many years. Many of my clients take the more comprehensive route and go for an over-all modernization. This is also easier to entrench among citizens and political decision-makers; after all, the time for such action is now and not tomorrow.

In a special “Light Workshop“ children aged 7 to 13 can get to know everything about the topic of light through experimentation. How does a laser work? And why does an LED glow? Acknowledged experts from physics and photonics answer these and similar questions and pack them in a graphic way in their study material that many school teachers are now also using in class. The pamphlets that can also be downloaded are packed full of experiments that you can easily conduct at home. The next Light Workshop will be held mid-April in Frankfurt.

Photos: therefore.com 08 | 09 After four years of development London designers Martin Riddiford and Jim Reeves present “GravityLight” – their small, glowing miracle. No electricity, batteries or solar energy are required to produce light with this unusual luminaire. Rather, as the name suggests, it draws the energy is needs from gravity: The downward movement of a weight creates potential energy, which is transformed by a generators into electrical energy – enough for 30 minutes of light. Especially for impoverished residential areas where roughly 1.5 billion people have no access to an electricity network GravityLight is a real alternative to the kerosene lamps often used.

The experience is what he calls Nordic Architecture. He is especially taken with Norwegian architect Reiulf Daniel Ramstad. Various persons such as Carsten Thau, Professor at the Royal Art Academy in Copenhagen or the Dutch architecture critic Hans Ibelings voice their views, and paint an almost romantic picture of architecture in Scandinavia. The book ends with an interview in which Jensen and Ramstad elaborate on the similarities and differences in buildings in Norway and Denmark, respectively. Dan Flavin first began to employ electric light in his art in the early 1960s. By using customary fluorescent lamps he succeeded in robbing the cool, artificial light of its function. Indeed, he raised it to an almost sensual and poetic level by transforming it in his installations into a space-creating element. The monograph Lights, which has been published in connection with the eponymous exhibition in Museum Moderner Kunst Stiftung Ludwig Wien (Museum of Modern Art in Vienna), features various commentaries by renowned art experts. A host of photos, prints and drawings document the one-time avantgarde artist’s oeuvre spanning almost 50 years. SPOT 3lux:letters 1 | 2013 DYNAMIC LIGHTING IN THE PUBLIC SPACE Pedestrian areas provide particularly useful examples to highlight the differences in how well frequented certain public spaces are over the course of the day and indeed the year. In contrast, the illumination of these areas is generally static. Yet precisely in these areas dynamic lighting that responds to people makes perfect sense. Photo: Rolf Hartbrich 10 | 11 The majority of the 9.13 million streetlamps in Germany work with inefficient, outdated technology, which will need replacing in the coming years. The current energy consumption of 4 TWh/a could be more than halved by switching to new technology, such as LEDs, saving 2 TWh/a in power output annually. We are sure to see this changeover in the coming years. LED manufacturers continually seek to outdo one another with ever new announcements of successes in terms of highefficiency light generation. The fact that LEDs have an even greater energy-saving potential compared to conventional light sources, something that should not be underestimated, often falls by the wayside. This includes their excellent adjustability in terms of brightness and light color as well as the direction of the light, which is easier to control thanks to the smaller size of LEDs. Making use of these options in the development of new dynamic lighting concepts would cause electricity requirements in this field to sink considerably further. The particular challenge here is that public space is used by many individuals simultaneously with different demands in terms of lighting, yet users generally are unable to directly influence it themselves. A simple dynamic lighting concept would be to adjust the degree of illumination depending on the number of users. The first pilot projects in this field have already proved a success. The University of Wismar has also launched a project together with Hamburg University of Applied Sciences and the University of Rostock as well as a number of light manufacturers to develop exemplary solutions for outdoor and indoor lighting systems. Given that LED systems allow for the modification, expansion or limitation of the luminous flux, light intensity distribution and color, and the color rendering quality in a luminaire, the required light quality can be configured individually in line with the respective application. In addition to the application, constants such as the architecture, volume or materiality for instance, and variables such as the climate, weather, frequency, rhythmic or arrhythmic events and other parameters can be considered in order to form models that allow for the dynamic yet pragmatic control of lighting. With the new design A harmonious picture: the pedestrian zone in Künzelsau with façade and tree lighting. possibilities afforded by LEDs, lighting in the public space can also be better adjusted to the specific architectural conditions, as well as allowing for the development of changing scenarios that are tailored to specific occasions. Such dynamic concepts are particularly well-suited to those areas in towns and cities that are subject to more foot traffic, such as shopping miles, pedestrian zones, parks and residential streets, where in addition to the safety aspect the design component is particularly important. Options within these new concepts include façade lighting and the strong illumination of pedestrian areas in shopping zones, supplemented by additional, non-planned lighting from display windows. Given that the minimum requirements as outlined by the legal standards in these areas are generally far surpassed, for reasons of design and lighting technology, there is great potential for saving energy and improving the formal quality of the light. The illumination of pedestrian zones could consist of several components: ǩ EDVLF LOOXPLQDWLRQ IRU WKH FHQWUDO ZDONLQJ DUHD DEVROXWHO\ necessary for foot traffic ǩ OLJKWLQJ WKDW DOVR LQFRUSRUDWHV WKH SHULSKHUDO DUHDV DQG creates distinguishable urban spaces in the evenings whose atmosphere is shaped by light ǩID©DGHOLJKWLQJIRUYHUWLFDOOXPLQDQFHHQDEOLQJWKHVSDFHWR be experienced to the full These three lighting components could be quite well covered using a single light source fitted with old technology. But with LED technology we can differentiate and develop different scenarios. The basic illumination is on all night, the atmospheric lighting until 10 p.m., whereas the façade lighting is switched off around 8 p.m., right after close of business. At its simplest, dynamic lighting enables fluid transitions. Yet it would also be conceivable to keep the overall illumination switched on for longer than usual in good weather and the increased foot traffic it brings with it. When the weather is bad, shoppers will presumably go straight home when the stores 12 | 13 SPOT 3lux:letters 1 | 2013 Various lighting scenarios at Kornhaus in Bad Doberan: street and façade lighting without (left) and with (center) additional light from inside and without the façade lighting (right). close, meaning that the atmospheric lighting could be switched off earlier. At Christmas time or on other special occasions the illumination could be adapted to suit the festive mood. In addition to a general logging of user traffic in the center, a differentiated response to specific, local needs areas would also be incorporated into such a concept. To some extent every single lamp could even respond to the respective situation autonomously. This would allow for even more scenarios that could include the reporting of an emergency situation. An even stronger differentiation would be conceivable in the walkways at shopping malls, for instance with the aim of fully exploiting the available daylight, aligning the color of the light with the color concept or balancing disharmonies with the targeted use of daylight. Seasonal and event-related scenarios also play a major role here. Unlike in the outside space, where the goal is to preserve the constancy of people’s perception of the public space, clearly defined changes are certainly possible inside, as here the focus can be set on the experience of the space itself. Moreover, the lighting can be very different in the morning compared to the evening, not only in consideration of the circadian rhythm, but also in response to the different patterns of behavior at different times of day. Previous methods of adapting lighting, for example to user traffic, are responsive measures, which only adjust the lighting after the event it has occurred. This is dissatisfying for the user because the environment should not change unexpectedly. Otherwise they would question their perception of the constancy of the space and thus the reliability of the ambient conditions. Knowledge of the stability of the environment is a key factor, influencing one’s sense of security and consequently the usability of public spaces. Thus the question arises as to which changes are tolerable in which timeframes and when we need to be particularly mindful of them. Sensor and control technology are able to process complex signals. As yet we have no way of ordering the various signals in line with various usage and environmental factors such that we have a model capable of determining the required lighting in the next unit of time. The intelligent combination of location factors and dynamic ambient and usage factors will enable maximum energy sav- Photos: Thomas Römhild ings while maintaining top quality in the illumination of public spaces. A model capable of depicting this correlation in sufficient quality in line with the locations needs to be developed to serve as the basis of a control program. But simple technical solutions are also conceivable for these new, model-like lighting scenarios, such as multifunctional lamps with a control system that registers the ambient conditions. Dynamic lighting concepts have the potential to further reduce energy consumption for urban lighting and other public spaces drastically, which would ultimately save on costs too. Prof. Dr.-Ing. Thomas Römhild born in 1957 in Hanover. He studied Architecture at the University of Hanover, where he also completed his doctorate in the field of lighting planning. In 1985 he started working at the University of Hanover as a research assistant and in 1995 was appointed professor at the University of Wismar, where he established the course “Architectural Lighting Design” in 2001. He has authored numerous articles in national and international architecture journals and various books. www.fg.hs-wismar.de 14 | 15 IMPRESSION 3lux:letters 1 | 2013 TIME-OUT Switch off and relax – where better to do so than a small mountain village? With just 6,000 inhabitants, Reutte is a market town in Tyrol on the banks of the Alpine river Lech. It is well known for its traditional Reutte Market Festival, an annual event that takes place on the first Saturday in August. The façade paintings that adorn the houses in the heart of the village are unique to the region. Rather than forming a uniform front of façades, each house stands alone at an angle to the street. The Franciscan Reutte Monastery and the ruins of Ehrenburg Castle are also worth a visit, before winding down for the evening, which is of course a natural end to the day in a place as tranquil as this.

Clemens Tropp Light planner Tropp Lighting Design The LED has acquired a significantly wider spectrum of colors, and LEDS now essentially offer a greater range of design options than conventional lamps. What role does light play in your designs and how have LEDs influenced your work? Clemens Tropp: For us, architecture and light working in harmony is one of the most important principles of planning. Our designs orchestrate buildings, lend them their own identity at night and create rooms with character and an individual atmosphere – always adapted to the relevant use. Because, in the past, LEDs have not always lived up to our quality standards for lighting, initially, we tended to be rather circumspect with them, using them mainly in cases where other forms of light were not suitable because of the way they were constructed, for instance, in joins, on ledges or on furniture. But now LEDs have really come on in terms of quality and we have now implemented the first projects in which we have utilized them to illuminate large areas. As a matter of principle, I consider LEDs to be the illuminant of the future and the really major changes still lie before us.

To what extent do you think OLEDs could be applied in the architecture of tomorrow? Clemens Tropp: There is a great deal of potential for the future here. The way that we approach planning will change completely when developments in this area have progressed and, for example, it becomes possible to include this form of lighting in surface materials such as foils. This will open up completely new possibilities in terms of applications, making lighting universally utilizable – from the door handle to the wall. When billions of pixels can be controlled individually we will have infinite possibilities for creating changing scenarios – revolutionary, from a design viewpoint. With regard to energy efficiency, as well, this technology could allow us to take a giant step forwards. Photo: Martina Pipprich 20 | 21 hive (Design University of Applied Science Mainz) Just a few years ago, the design scope as regards light planning and/or installation was still extremely limited, if only by dint of the lamps’ size. Today, this is no longer an obstacle facing designers. Which LED light installation left a lasting impression on you and what fascinated you the most about it? Clemens Tropp: For me this was “hive”, an interdisciplinary project that we realized at the University of Applied Sciences in Mainz for Luminale 2010. As a team made up of professors AnnaLisa Schönecker and Klaus Teltenkötter, artist Andreas Muxel and the students we used LED technologies to create something special in a sober, stark environment: 1,600 LEDs hovering like a swarm of insects over a pond. From the shore, visitors were able to observe their movements as animated light on the swarm. Changing the color and the brightness resulted in basic moods that changed constantly. This made for an atmospheric overall experience that elicited great enthusiasm and could scarcely have been realized with conventional lighting technology. Clemens Tropp, born in Weilburg in 1962. Studied Electrical Engineering at the Technical University of Darmstadt until 1987. After many years of experience in lighting planning, he established a bureau, Tropp Lighting Design, in 1998, which focuses on illuminating architecture. Alongside his profession as a lighting planner, Clemens Tropp has been Professor of Lighting Technology on the Interior Design course at Mainz’s University of Applied Sciences since 2009. www.tropp-lighting.com Michel Suk: To be able to actually shape a light source and thus Hannelore Deubzer: Although the use of LEDs is comparable to create a unique lighting fixture is a designer’s dream.

The Kita am Linsenberg day nursery in Kriftel, Hessen, shows what a modern nursery offering children and teachers a varied learning and playing environment can look like. Moreover, the new building stands out for its innovative energy concept. By Ole Hempel The white walls in the new nursery make the rooms appear bright and friendly. Gradually, drawings and objects produced by the children are to fill the walls (right). Children in the rooms on the upper level can access the garden directly via exterior stairs (below).

On the upper level, safety nets (which the children have partly decorated with colored paper and balloons) prevent any accidents. All the other rooms can be accessed from the lobby, which is ventilated and lit naturally via a skylight. 26 | 27 ARCHITECTURE 3lux:letters 1 | 2013 The spacious multi-purpose room can be used by the children for sports and gymnastics, as well as for events and parties. A general effort by politicians to expand nursery provision has served to raise people’s awareness of the special needs of small children. What daycare centers should most definitely not be is places where children are simply dropped off and deposited. Instead, they need to offer an environment where youngsters receive important stimuli in a community setting and can learn social behavior. This is also the concept behind the Kita am Linsenberg in Kriftel, which in August 2012 moved to a new building in a highly visible location at the entrance to the town. The old complex, which is located on the opposite side of the street, was declared unsafe in 2002, and modernization did not really make sense. However, for financial reasons and the difficulties involved in finding a new location, plans for a new building did not start to take shape until 2008. Architecture studio Schneider + Sommer Architekten from Idstein drew up plans for the general contractor HOCHTIEF Solutions, which in 2009 impressed the jury presiding over the public tender competition. The plan foresaw a cylindrical structure with a stepped two-story design. The developed area was reduced in order to give children and instructors as spacious an outdoor area as possible over 3,400 square meters. Critics, who have described the building as “pompous”, claim that the concept combines two nurseries in a single building. For aside from the five kindergarten groups, two so-called U3 groups with children aged two to three have also moved into the new premises. Even the street layout meets the specific needs of a daycare center. The approach was realized as a loop for stopping and turning, meaning there are no intersections at the entrance to the building, increasing safety. The building has a spacious main entrance leading into the adjoining curving lobby naturally illuminated by skylights. All the other rooms are accessed from here. The ground floor houses the separate administration area and the nursery rooms for the under-threes with their own outdoor There are ample ways for the children to play in the group rooms. Pictures they have painted on the walls and windows lend the rooms an individual touch. area. This location was chosen to allow the youngest children to join in the daily games and fun of the older children aged four to seven, enabling them to gather vital experience in dealing with “big children”. At the same time, the rooms are designated solely for them, offering them a place of refuge. The nursery walls are painted in bright white, not least of all to show off to their best advantage the objects they have made and pictures they have drawn. That said, the children can make as much mess as they please in the creative room; splashes of paint on the walls are allowed and are part of the concept. The activity and multi-purpose room can also be reached from the lobby and can be completely opened up or partitioned off using a sliding door. What’s more, the storeroom can be converted into a stage. All the group rooms and the activity and multi-purpose room have direct access to the spacious outdoor area. As the various terraces are roofed, they can also be used in bad weather. Children and teachers reach the upper story, which is set back and contains four group rooms and two sleeping rooms, via a slightly curving staircase. Roof terraces and balconies enable access to fresh air here too. The new daycare center is also worth a closer look as regards its energy concept. Overall the center meets the standards of a low-energy building. For example, the building’s shell is made of highly insulating components, windows and doors are triple glazed and the floor slabs are fitted with thermal insulation roughly 20 centimeters thick. Hot water is produced via a solar installation on the roof and during the winter months the triple glazing generates valuable heat, which is stored in the solid wall components. A regulated ventilation system is in place throughout the whole building. Using cross heat exchangers, the ventilation system achieves a minimum of 60 percent heat recovery and makes manual ventilation unnecessary. The installation of LEDs throughout the building spells additional cost savings. 28 | 29 ARCHITECTURE Longitudinal section Floor plan of the lower level 3lux:letters 1 | 2013 The two-story nursery has a spacious outdoor area for the children to run around and play in. TECHNOLOGY The level framing highlights the luminaire’s precision and slender shape. The flush-toceiling concept integrates the framing into the ceiling as a graphic element. Belviso The recessed LED luminaire with a microprismatic cover can be integrated into both sawn ceiling openings and modular ceilings. The mounting rail can either be concealed or deliberately left exposed as a design element. The luminaire, measuring 62 x 62 cm, is particularly well-suited to innovative, particularly striking illumination concepts, as well as providing additional lighting, for instance in sales, office or conference spaces, foyers, hotels or restaurants. The luminaire conforms to the DIN EN 12464-1 anti-glare standard. In combination with the highly efficient microprismatic cover, the four integrated LED panels produce harmonious light with even output. The sheet-steel body is white and has a solvent-free powder coating. Belviso is also available as a digitally dimmable version.

It shapes the cityscape and is a major tourist attraction. To enable this important marketplace to be used comfortably all year round, Eder Biesel Arkitekter from Stavanger designed a building that serves the Fish Market as a roof and moreover accommodates the tourist information center and “Norwegian Seafood Center”. By Marina Schiemenz Bergen Harbor with its numerous historical buildings and UNESCO World Heritage Site Bryggen form the perfect backdrop for the new market hall for the historical Fish Market.

When the glass façade is fully open, the indoor and outdoor space seamlessly merges; even the ground covering continues inside the building. 34 | 35 ARCHITECTURE 3lux:letters 1 | 2013 Floor plan ground floor (above) and first floor (below) In the center of Bergen in Norway, opposite the former Hanseatic quarter Bryggen, which was listed as a UNESCO World Heritage Site in 1979, the traditional Fish Market is a lively, bustling place all year round. In recent years calls could increasingly be heard for a market hall to meet new demands in terms of convenience and hygiene. Eder Biesel Arkitekter’s design won the 2008 competition for a new building. On the one hand the architects attached great value to preserving the views of historically important buildings and the sea, and on the other they didn’t want to simply hide the Fish Market in a building. Rather, they wanted to give it a “weather cover” that erases the boundaries between the market square and market hall. The structure completed in May 2012 forms a protective roof over the Fish Market, with the square’s granite cobblestones continuing underneath it. The flexible glass façade protects it from bad weather and can be opened on sunny days. Thus the space is connected: the stalls inside combine with the outdoor market to form the Bergen Fish Market. Before 1900, the natural harbor was defined by a meandering quay line. The architects laid a visible strip of wood in the ground engraved with the names of the original owners of the moorings following the course of this line. Large, backlit historical pictures and photographs inside the hall tell the story of the market. In addition to the public section, a service area with a number of technical rooms is spread over three stories. The roof of the market hall forms the “Norwegian Seafood Center” and tourist information office with panorama windows overlooking the historical city center. The choice of colors and materials for the building is likewise oriented on the historical architecture: On the façade wooden slats in the typical Bergen colors ocher yellow, dark red and white alternate in arrangement and density, becoming denser at the rear of the building. The public areas on the upper story afford visitors an impressive view of the harbor and historical architecture. TECHNOLOGY Alinio LED The cuboid Alinio allows for an even illumination of the space and light strip over the desired length. The modular concept with various lighting modules offers a lot of freedom when it comes to design and can be adapted to suit the spatial environment at hand. This makes it easier to cater to customers’ individual wishes and requirements. Thanks to the filigree casing made of silver-gray, finely structured aluminum, the luminaire does not need to be concealed in the ceiling, but can also hang down without making for an eyesore. Alinio is available in three different lengths and can be used as an individual luminaire or as a continuous row of light strips. Moreover, the luminaire, which is fitted with an electrical transformer, can also be digitally dimmed. Luminous intensity distribution Modern technology and simple design: The Alinio combines both and thus can be used almost anywhere. SERVICE 3lux:letters 1 | 2013 PLANNERS ASK, MANUFACTURERS ANSWER In the everyday work of a planner, many a question comes up which cannot be found in any handbook. Answers to such questions are given here by the experts of TRILUX who also tell you one or more tricks. Do energy-saving measures in a municipal renovation project receive public funding? Thomas Kretzer Managing director TRILUX Vertrieb GmbH Efficient, trailblazing LED technology from TRILUX, such as here at the new Fraunhofer Institute in Stuttgart, makes a decisive contribution to securing funding for your municipal building project. Photo: Trilux/Christoph Meinschäfer Fotografie 36 | 37 This year, for the third time, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) is supporting municipal building renovation projects that result in a clear reduction of the buildings’ CO2 emissions. Since early 2013, local authorities, municipal associations and firms as well as cultural, social and ecclesiastical institutions have been able to file an application for investment subsidies. This is intended to smooth the way for towns and especially smaller communities that have only just commenced their climate protection measures to embark on sustainable planning. The Federal Environment Ministry has accordingly amended the respective municipal directive, further expanding the wide range of subsidies it offers. As a fixed component of the Ministry’s climate protection campaign, the focus is on switching over indoor and hall lighting to energy-saving LEDs – with up to 40 percent of the overall investment volume being state funded. Further subsidies are available for switching over outdoor lighting to LED technology. And the move has proven to be highly successful: Photos: Trilux The new subsidies offered by the Environment Ministry can also be used for the professional lighting of streets, sidewalks and cycle paths. Average energy savings of up to 75 percent were achieved in projects realized in recent years. As a specialist for sustainable and efficient lighting solutions in the LED area, TRILUX is offering a special all-round service on the new subsidies available, which covers all aspects relating to the new municipal directive and the potential subventions. Property developers and planners will receive support in every phase of the application procedure from determining their needs to acquiring data, selecting products, evaluating efficiency and calling for bids to realization. From the word go, trained specialists will personally handle the applications and coordinate the precise order of the procedure using a personally devised checklist. Services such as lighting planning and efficiency calculations are non-binding and free of charge for developers, as the final decision on a tender is only made once the application has been completed and the subsidy approved. Moreover, TRILUX provides customized software solutions for the application and lighting planning and has specially created a web page for the subsidy program (www.trilux.com/de/kompetenz/bmu-foerderprogramm-2013). Alongside additional information and specific examples, it also offers a new, wide-ranging service and financing concept to assist developers and planners in implementing their project. All these components come together perfectly, making the comprehensive TRILUX product range the ideal basis for a successful application. After all, it is thanks to highly efficient LED lighting for indoors and outdoors coupled with intelligent regulation technology that the requisite CO2 savings of 50 percent for indoor lighting and 60 percent for outdoor lighting can be made. Applications can be submitted until March 31, 2013. SERVICE 3lux:letters 1 | 2013 5041 LED As of April 2013 the tried-and-true ceiling light 5041 will also be available in an LED version and thus is eligible for a subsidy from the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. Moreover, the technological advancement of the luminaire offers a number of new options compared to the version with T5 fluorescent lamps. An asymmetrical version of the 5041 is also available for illuminating the black/whiteboard, to ensure optimum lighting in classrooms. Photos: TRILUX 38 | 39 The LED version differs only in its technology, not in the clear design of the tried-and-tested T5 version. The new LED version of the 5041 is available as a single unit or continuous strip lighting and is particularly well suited to illuminating offices and classrooms. Not only does it provide the necessary glare limitation and optimum luminance for on-screen working, but with its two lumen packages (4,000 and 3,300 lm) it enables the user to respond to various spatial situations with different levels of illumination (300 and 500 lx). The 5041 LED is no different from a conventional luminaire in terms of appearance, as a diffuser tube connecting the three LED modules dissolves the individual spots of light, thus enabling even light distribution. The tried-andtrue, high-gloss RPX grid with silver coating achieve a reflection factor upwards of 98 percent. In addition, the luminaire is available in versions with a dimmer or regular switch (with electronic transformer). As an optional feature, an integrated light management system saves additional energy based on the amount of available daylight and presence detection technology. A2 BAT Environmental and climate protection are gaining ever more importance. Years ago now step-by-step plans were introduced in many areas to gradually update long-outdated technologies in line with energy-efficiency standards. One of these plans involves the successive replacement of functional elements in outdated fluorescent lamps with modern technology. And TRILUX is realizing today what will not be required until 2017. A small object with advanced technology: This electronic ballast features technology with energyefficiency class A2 BAT. In 1981 TRILUX’s in-house development team came up with the first electronic ballasts, and by 1990 all its luminaires were fitted with them. TRILUX launched the first climate protection initiative as early as 1995 in the form of the project “2:1 für unser Klima” (2:1 for our climate). This was followed by further campaigns and technological improvements – the topics “energy efficiency” and “sustainability” were declared a top priority. Thus it is hardly surprising that today TRILUX is already responding to the standard requirements of tomorrow. The EU Ecodesign Directive 2009/125/EC requires that energy-guzzling luminaires be gradually replaced by more environmentally friendly alternatives. Thus TRILUX has now made it standard practice to integrate with energy-efficiency class A2 BAT (Best Available Technology) and a lifespan of up to 75,000 hours into its switchable T5 and T8 luminaires electronic ballasts. This will save both costs and energy, namely, the amount needed to supply a small town with 4,000 households with electricity for a whole year.

Boasting a central location with a view of the Großmarkthallen market halls and HafenCity, this is a cutting-edge meeting facility where interested clients can not only learn more about the latest LED lighting concepts, but experience them first-hand in an impressive environment. When choosing an alternative location for the TRILUX Center of Competence in Hamburg, the focus was on creating a unique and ambitious architectural environment. This is to be a place where interested clients come to learn about trailblazing LED lighting concepts and light management systems in stylish surroundings and receive advice from expert staff. Following an intensive search, TRILUX found what it was looking for in close proximity to the harbor and Großmarkt Hamburg wholesale market and moved into the redesigned fifth story of a listed 1960s high-rise in late 2012. This prime downtown location offers the ideal environment for the new Center of Competence, directly adjacent to the eastern part of the HafenCity Hamburg urban extension project. The 450-square-meter space, which had been completely gutted, offered optimum conditions for the realization of an integral spatial and lighting concept, whereby TRILUX was able to determine the lighting planning and interior fittings itself. The result is highly impressive: an open and invit- ing space, shaped by floor-to-ceiling glass elements and a fluid sequence of spaces, in unique combination with the technology of cutting-edge lighting. At the Hamburg Center of Competence the client area and workplace fuse, creating a space offering visitors an unparalleled, tangible experience of modern LED technology. The overall concept is underscored by high-grade interior design and decorative motifs inspired by the Hanseatic city itself. Even at the first major event on the occasion of the official opening, the ambitious project impressed almost 200 customers who had come to gain a first-hand impression of the new lighting competence center. Hamburg is the base from which the new TRILUX Center of Competence serves the entire north of Germany. This includes a wide-ranging service portfolio encompassing lighting planning, technical support (lighting/ electrical installation) and business support services, which has long proved an excellent basis for successful collaboration with customers as partners. At the Hamburg Center of Competence the customer area and office merge into one: Customers can view various lighting concepts at the actual place where TRILUX staff work.

A welcome change to the gray that colors day-to-day life at the hospital – for kids and grown-ups like. By Philip Teleu London-based design agency, Jason Bruges Studio, is known for its interactive works and installations which tread the fine line between art and architecture. In 2012, the Brits were awarded a commission by London’s Great Ormond Street Hospital for Children to create something to distract their young patients and still the little ones’ fears before their coming treatments. Their response to the brief: a wall depicting a woodland scene perforated with a panoply of holes, which the designers then mounted onto the existing wall in the hallway. Behind this new decorative façade, the designers installed a number of LED panels that can be used to create a display of light patterns. In-keeping with the overall theme, the scene shows a parade of different woodland creatures like deer, birds and hedgehogs, joined by frogs and horses, who accompany the little ones’ on a short leg of their journey through the hospital. But the installation isn’t just for patients; it also affords parents, doctors and nurses alike a special moment of quiet, distraction and fascination. www.jasonbruges.com Photos: Iwan Baan From a distance it looks like a lowing, impenetrable ravel, but when you step inside its becomes a unique, three-dimensional experience LEBBEUS’ LEGACY The Light Pavilion is one of four installations within the new superblock by Steven Holl in Chengdu. Lebbeus Woods sadly died last year, making this the first and last of his works to actually be constructed. By Stefan Staehle By day the structure with its entanglement of iron girders looks something like an architectonic deconstruction of its surroundings, while at night it is transformed into a fascinating display of illuminated contours. At the heart Steven Holl’s superblock “Sliced Porosity”, Lebbeus Woods and his partner Christoph A. Kumpusch have created a place that affords its visitors a glimpse into the future of architecture. A future in which the space that surrounds us inspires us to act, expands our horizons and makes for new experiences. The Light Pavilion is an open and accessible area within the block, which eludes a precise architectonic classification with its overlay of stairways, balconies and illuminated structures. Very much in the spirit of his intellectual mentor who always met the notion of conformity in architecture head-on and whose high standing within the world of architecture can most notably be attributed to his spectacular pictorial architecture, which so innovative in its expression escapes any kind of categorization. www.lebbeuswoods.net ART 3lux:letters 1 | 2013 A canopy of recycled lampshades illuminates Pittaki Street in Athens’ historic center, from which you can also see the illuminated Acropolis.

A SKY OF LIGHTS FOR PITTAKI To bring light to downtown Athens, paralyzed by crisis, artist group beforelight collected old lampshades for a delightful art project in the public space. By Franziska Bettac There is not much good news coming out of Athens these days. The financial crisis has forced many businesses to close and public life is coming to a standstill in the streets of the historic center. Pittaki Street, one of the many winding alleyways in the Psiri neighborhood, is seeing ever more vacancies. Now, with the support of over 100 residents, the artist group beforelight has realized a participatory art project that breathes new life into the street and enlivens the neighborhood. Over a period of several weeks, residents, friends and volunteers came together to prepare the large-scale installation. An empty store was transformed into a temporary workshop, where old lampshades and mounts that had been donated were repaired and weatherproofed. The communally created light installation consisting of 150 luminaires is now to illuminate downtown Athens, literally and metaphorically, for six months. The artists realized a similar installation for a street festival in Thessaloniki back in 2010. Their current project now also does justice to beforelight’s social focus, namely to network the people of the city. www.beforelight.gr Photos: Tuomas Uusheimo, Hannu Iso-Oja, Tapio Rosenius Inspired by the original, rusty façade the silo’s interior has been decorated in similar color tones. The work of light art can be seen from miles around and goes out every night at 2.30 a.m. with the departure of the last ferry of the day. OLD SHELL, NEW SPLENDOR It was the natural landscape on the Gulf of Finland that inspired the Lighting Design Collective from Madrid to transform an unused oil silo into an illuminated art object to be enjoyed by the public. By Patricia Sahm At 17 meters high and 36 meters in diameter, the former oil silo sits on an island just off the Finnish coast with a direct view of the capital Helsinki. A reference to the year Helsinki became World Design Capital 2012, the silo’s façade has been perforated with precisely 2,012 holes. The interplay of artificial and natural light allowed the Lighting Design Collective to create some particularly impressive illuminations. Behind the façade, a total of 450 mirrors that flutter in the wind reflect the sunlight and lend the silo and the water’s surface around it a glistening shine. During the day, the rays of sunlight permeate the façade and create a mottled light display in the rust-red interior of the colossal steel structure, while after nightfall 1,280 warmwhite LEDs behind the openings in the façade imitate the fluid motions of flocks of birds. A computer program developed specifically for this project uses constantly measured data relating to wind strength and direction, temperature and precipitation to calculate the birds’ potential flight characteristics and translates them into a magnificent light display. A fascinating show that can be seen from miles around. www.ldcol.com CURIOSITY 3lux:letters 1 | 2013 Photos: Office of Victor Vetterlein 46 | 47 FOR THOSE LITTLE HUNGER PANGS By Patricia Sahm The new desk lamp by New York designer Victor Vetterlein won’t last very long around fans of gummy bears; for the light object’s name “Bite me” calls the user to do just that. A mix of natural glycerin, water and agar-agar (an gelatinous substance made of seaweed) forms the material basis for this edible lamp. A range of food colorings give the objects a bright, cheerful appearance, while the four flavors, orange, cherry, blueberry and apple ensure that it tastes just as good as it looks.

Bon appétit! www.victorvetterlein.com SOURCE GHOST LIGHTS Ghost lights, also called ignis fatuus or will-o’-the-wisps, are rare light phenomena whose existence was long doubted. As the shimmering lights, only a few centimeters high and generally blue or green, seldom appear, they even used to be dismissed as superstition. Legend has it that these supposed spirits of nature, which mostly appear near bogs and swamps, deliber- ately lead people astray and consequently to their death. The flickering lights deceive tired wanderers, who think they can see a lantern or illuminated building. Believing they have reached their destination, they sink and suffocate in the swamp. In some regions people claimed that these phenomena just above the surface of the water were the undead or the souls of suicide vic- tims, unbaptized children who had died or defrauders. Yet they were not all bad spirits: One myth claims that a treasure awaits the one who is brave enough to dig for a ghost light at the spot where it appears on Walpurgis Night. To this day ghost lights have not been fully researched, as they appear only rarely and only for a few seconds. Nonetheless, scientists believe they are a form of bioluminescence produced by an edible mushroom or insects. Another theory puts the phenomenon down to rising fermentation gases from tree stumps or grass that spontaneously ignite. Unfortunately, as bogs and swamps increasingly disappear so too do the rare ghost lights and the time we have left to research them in depth.
