4. Title USGBC/GBCI – LEED • Founded in 1993, LEED begins 2000 • LEED AP exams begin 2001 (181,000 LEED APs to date) • 13,000 member organizations to date • GSA requires LEED Silver beginning 2007 (LEED Gold beginning 2013) • USGBC spins of GBCI in 2008 • Current LEED rating programs begins 2009

6. Title Gbi – Green globes • Building Research Establishment’s Environmental Assessment Method (BREEAM) begin in Canada (1996) • The Green Building Initiative – In 2004 acquired the rights to BREEAM, now Green Globes • GBI became the first building rating system to be an accredited standards developer by ANSI (2005)

7. Title Green Globes vs. leed • Fees are similar ($3,000 to $5,000) • Time to complete documents is 25% of that required by LEED • Forest certifications (4 vs. 1) • Weighted Criteria • No Prerequisites • Removes Non-applicable Criteria (more flexibility) • Partial Credit

8. Title Green Globes vs. leed • Four level of performance (1-4 globes vs. Certified, Silver, Gold, Platinum) • Allows regional variations • Energy • LEED (benchmark against hypothetical building model) • GG (benchmark against regional performance similar to ENERGY STAR) • Key difference is flexibility

13. Title ASHRAE - Beq • Compares As Designed (A – F) to Operational performance (A – F) • bEQ is the “next step” beyond the ENERGY STAR (gives a path forward) • Requires an ASHRAE Level 1 audit • bEQ requires a PE or ASHRAE certified professional to submit documentation ($500 fee), although worksheets are available for free

14. Title ICC – IGCC • International Code Council developed the first model code for minimum green requirements for new and existing buildings • Relies on the International Energy Conservation Code (IECC) and ASHRAE 189.1 • Goal is an enforceable green building standard
