Leadership in Energy and Environmental Design v2.0

1. Leadership in Energy and Environmental Design v2.0 Lecture 9

2. LEED™ Green Building Rating System • US Green Building Council • Leadership in Energy and Environmental Design (LEED)™ • US national “green” building certification • Consensus-driven & broad representation • Commercial, Interiors, Residential

3. Why “green” rating systems ? • Definition, guidance, validation • Leading edge in design & construction • Marketing advantage for all parties • $ savings (energy, water, maintenance, wastes, productivity) • Human & environmental health • Risk reduction global & local • Increased value of construction

4. Green Building Assessments • Commercial and residential • BREEAM • BEPAC • Austin Green Builder Program • Green Building Challenge 2000 • Florida Green Building Coalition

5. “Green” Building Programs & Labels - US

6. United States Green Building Council The LEED Green Building Rating SystemTM is a voluntary, consensus-based, market-driven building rating system based on existing proven technology. It evaluates environmental performance from a whole building perspective over a building’s life cycle, providing a definitive standard for what constitutes a “green building”

7. LEED Components • Prerequisites • Flexible credit system • Existing “best practice” codes • Four levels of effort / rating • Performance-based
