1 Specifying GREEN A presentation by Building Systems Design, Inc. Robert Paul Dean, AIA, CSI, CCS

2 Preview Overview of Green Building –Definitions –Difficulties Introduction to USGBC and LEED –Rating Systems & Criteria Categories –LEED, Limitations & Opportunities Green Specifications –Importance of early performance specs –Strategizing for optimum credits Tools & Resources –Websites –Specification Tools

3 Definition 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 Green Building: Sources: CSI-DBIA PerSpective and USGBC

4 Definition 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 Green Building:

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 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 LEED-NC

9 Green Building Rating System – Criteria Categories –Sustainable Sites –Water Efficiency –Energy & Atmosphere –Materials & Resources –Indoor Environmental Quality –Innovation & Design Process
