Groene Hoogbouw - Duurzaam Den Haag

Groene Hoogbouw
De Stichting Het Haags Milieucentrum streeft naar een zo duurzaam
mogelijk Den Haag en omgeving. Ze doet dit op twee manieren:
door zelf activiteiten te ontplooien en door plaatselijke en regionale
natuur- en milieuorganisaties te ondersteunen.

The building can be regarded as a ‘system’
with it’s site and surrounds as it’s
‘environment’:

The ‘General Systems Theory’ model for describing a
system and it’s environment, and the exchanges
between them
The economics of environmental degredation
•Our human welfare
is related to
•Our material standard of living
which depends on the
•Provision of manufactured goods
which in turn requires
•Consumption of natural capital
which means
•Extraction of natural resources
which involves the
•Discharges of wastes
which result in
•Environmental pollution
The Designer’s Role:
by design and by innovation,
to reduce, eliminate and improve
efficiencies in these aspects
Some of the consequences of buildings
on the natural environment:

Ecological design involves not just
architecture but also includes:
Ecology and ecosystems studies,
Environmental biology,
Landscape architecture,
Environmental conservation,
Resource management,
Materials production and sciences,
Materials recycling,
Materials economics,
Low energy design,
Environmental pollution control,
Etc.
The need for an unified theory of ecological design to integrate these aspects
The built system’s enclosure
• areas to be enclosed (optimise on partial and unenclosed spaces)
• impacts of users’ and system’s activities (e.g.residential, industrial, etc.)
• provision of operational environmental systems (see below)
(Increasing energy
& materials inputs)
• Passive Mode
• Mixed Mode
• Full Mode
• Productive Mode
Optimise,
The built system’s operational systems
Optimize passive mode strategies
(before adopting other modes):
• by Building configuration
• by Building orientation
• by Façade design
• by Solar-control devices
• by Built-form envelope colour
• by Natural lighting
• by Vertical landscaping & planting
• by Wind & natural ventilation
• by Others
Strategies for design detailing of building
components:
• Reuse
• Recycling
• Durability
• Efficiency
• Minimize waste
• Environmental integration
• Re-manufacture
• Repair/maintenance
• Upgrading
• Refilling
• Replacement
Greening the large building as continuous
‘vertical landscaping’

Average photovoltaic- cell energy
output = 17.6 kWhr/sq.m
Total sunlight hours
per day = 12 hours
Daily energy output
= 2.04 kWhr.sq.m
Area of photvoltaic
