Project 1
Sustainable energy: an architectural precedent
Please e-mail your choice of topic for Assignment #1 to the TA for approval.
This assignment consists of the preparation of a report on an energy
system. Students are asked to explore a topic (i.e. passive solar systems,
wind energy, recycled materials, green roofs , etc.) through the use of
architectural precedents.
For this portion of the assignment, students will make a brief presentation
(no more than 5 minutes -PowerPoint) during the second part of the lectures.
Assignment is to be completed in groups of 3 or 4.
Percentage of final mark: 30%

Context
Toll on the Environment
Because of this unlimited
consumption of natural resources
today:
Global Warming
Ozone Depletion
“Every living system is in decline
and the rate of decline is increasing.”
-The Union of Concerned Scientists
Notable problems include:
• Global warming
• Ozone depletion
• Acid rain
• Soil, water, and air pollution
Air Pollution
Soil Erosion & Water Pollution
• Loss of biodiversity in soil and
groundwater resources

• 50% of CFC production
• 33% of total CO2 emissions
• 40% of landfill material
• 30% of building suffer from “sick

Buildings
Typical North American commercial
construction causes:
• 2.5 pounds of solid waste for
every square foot of floor space
• Land and habitat disruption
• Water run-off & pollution
• Soil erosion
This energy consumption results in:
• Pollution
• Ozone depletion
• Global warming
• Human health problems

The “Green Building” movement
began as a reaction to:
Bateson Building, Sacramento, California,
1977, Sim van der Ryn

California, 1973
• Oil shortages
• Political events
• Environmental events
The early part of the movement
focused on energy conservation.

C2000
C2000
The C-2000 Program for
Advanced Commercial
Buildings was a small
demonstration program for
high-performance buildings,
developed and sponsored by
the CANMET Energy
Technology Centre (CETC) of
Natural Resources Canada.
The emphasis of the program
was on energy performance
and water conservation, but
criteria was also developed for
maintenance of site ecology
and improved levels of indoor
environmental quality.
C2000
Since the program launch in
1993, 24 buildings were
designed using the C-2000
requirements, twelve of which
achieved the design targets and
were constructed.
C2000
Initially it was thought that new
technologies would be the key
to high performance, the
experience of the program,
however, showed that the
design process itself is the most
important contributor to the
realization of high performance
buildings.
C2000
The initial phase of the C2000 program is now closed.
The knowledge and expertise
resulting from this green
building demonstration
program are now serving to
prepare Integrated Design
Process (IDP) guidelines and
energy performance
assessment tools.
