Toll on the Environment
Because of this unlimited consumption of natural
resources today 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
  • Global warming
  • Ozone depletion
  • Acid rain
  • Soil, water, and air pollution
  • Loss of biodiversity in soil and groundwater
    resources

Buildings Contribute to
  • 17 of fresh water flow
  • 25 of wood harvested
  • 50 of CFC production
  • 33 of total CO2 emissions
  • 40 of landfill material
  • 30 of building suffer from sick building
    syndrome
  • 40 of the worlds energy annually
  • 60 of the worlds electricity annually
  • 5 billion gallons of water per day to flush
    toilets

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

Post Occupancy Evalutions

How satisfied are you with the building
overall? The average score of 2000 responses on
buildings in CBE database was 4.78 4.0 is a
neutral score. Choi occupants are more satisfied
than average at 5.4 Liu occupants are slightly
dissatisfied at 3.92

1970s Green Building Movement
The Green Building movement began as a reaction
to
Bateson Building, Sacramento, California, 1977,
Sim van der Ryn
Village Homes Subdivision, Davis, California, 1973
  • Oil shortages
  • Political events
  • Environmental events

The early part of the movement focused on energy
conservation.

C2000
35
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.

36
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.

37
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.

38
C2000
  • The initial phase of the C-2000 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.

Leadership in Energy Environmental Design
(LEED)
  • A leading-edge consensus-based system for
    designing, constructing, operating and certifying
    the worlds greenest buildings.
  • Created by US Green Building Council, adapted for
    Canada by Canada Green Building Council
  • LEED examines and assigns points in
  • Sustainable Sites, Water Efficiency, Energy
