3. Definition Green Building:
Design and construct facilities that minimize adverse effects on the exterior environment, enhance the quality of the indoor environment, and minimize consumption of energy, water, construction materials, and other resources -- both initially and on a life cycle basis
Sources: CSI-DBIA PerSpective and USGBC

4. Definition Green Building:
Many potential conflicts exist between the various green building goals, so designing and constructing ecologically sound buildings is a delicate balancing act
Achieving reasonable results requires that we evaluate as many issues as possible and attempt to use the most cost-effective green building strategies available for a given situation

5. U. S. Green Building Council
originated in 1993
the nation’s foremost coalition of leaders from across the building industry working to promote buildings that are environmentally responsible, profitable and healthy places to live and work.
members work together to develop LEED® products and resources, the Greenbuild annual International Conference and Expo, policy guidance, and educational and marketing tools that support the adoption of sustainable building.

6. LEED Leadership in Energy and Environmental Design
a national consensus-based, market-driven building rating system designed to accelerate the development and implementation of green building practices
a system for designing, constructing and certifying green buildings

7. LEED-NC Green Building Rating Systems – Numerous criticisms:
lacks scientific rigor
certification requires significant additional effort at every phase, including final submittal requirements
LEED-NC designed primarily for office buildings
insufficient attention to LCA:
embodied energy
waste disposal
potential for global warming
ozone depletion of building products

8. LEED-NC Green Building Rating System
LEED-NC: 2.1 currently in use; version 2.2 is expected in fall of 2005
LEED-NC: Version 3.0 incorporating LCA features also under development

17. LEED-NC Green Building Rating System –
Achieving LEED certification will depend heavily on early design decisions, including site selection
Waiting until the construction documents phase to begin making green decisions may make achieving LEED certification difficult or impossible
