Green Building Labels LEED Rating System Green Point Rated System U.S. Green Building Council Build It Green • Points define four certification levels • 50+ points define degree of ‘Green’ • Focused on commercial new & retrofit • Focused on single/multi family • 9000+ rated projects since 2000 residential • Goal of 10,000 units rated by end of 2008 • Two complementary standards have emerged as leaders: • Widely recognized and consensus-based • Consistent and quantifiable rating criteria, ‘menu’ of options/choices Independent 3 rd -party verification •

Observations • Mandatory CALGreen- “It’s the law” • Combination of • Basic quality practices • New areas • Duplication/subtle changes to other code
Observations Strengths of Labels Relative to Tiers • Clearly defined & tested • Common guidelines and verification • Highest standards – no ceiling • Recognition beyond code • Require beyond-code energy efficiency • Reinforce voluntary application of labels
Policy Recommendations 1. Prioritize education and enforcement of CALGreen mandatory provisions 2. Continue to use LEED/GPR for “reach” codes 3. If using a CALGreen Tier as a “reach” code, accept LEED/GPR in lieu of the Tier
