  2. Where LEED fits

  3. General Service Administration study of 5 green building standardsSustainable Building Rating System Summary July, 2006 • LEED • BREEAM • GBTool • CASBEE • Green Globes Reasons why LEED different, strongly preferred by GSA • Covers all project types • Tracks quantifiable aspects of sustainable design and building performance • Trained professionals verify LEED • Well defined system for incorporating updates: consensus -based • Most widely used rating system

  4. LEEDTM Point Distribution Five LEED credit categories

  5. BofA Headquarters

  6. Greening Affordable Housing Plaza Appts., San Francisco 7000 units of efficient, green affordable housing in 2 yearsPartners Include:Enterprise Community Partners Fannie Mae JPMorgan Chase BofA Citibank AIA NRDCSee:www.greencommunitiesonline.org/about-partners.asp

  7. Productivity Gains from High Performance Lighting Systems Source: Carnegie Mellon University Center for Building Performance, 2005

  8. Health Gains from Improved Indoor Air Quality Source: Carnegie Mellon University Center for Building Performance, 2005

  9. Energy Efficiency Plus Health & Learning Benefits of Green Schools 33% energy efficiency improvement over conventional design plus Enhanced Indoor Air Quality: Increased Learning, Productivity & Performance (3%) Increased Future Earnings of Students (1.4%) Reduced Asthma (25%) Reduced Colds and Flu (15%) Reduced Teacher Turnover (3%)

  10. Third Creek Elementary School (NC) 800 students moved from 2 older schools in 2002Same students and teachers3 years prior to move 60% of students on grade level in math and reading2 years post-move 80% on grade levelNo other changes

  11. The Financial Benefits of Green School Design ($/ft2)

  12. Benefits not Quantified • Reduced Teacher Sick Days • Heat Island Reduction • Lower Operations and Maintenance (O&M) Costs • Enhancement of generating system reliability and improved power quality • Insurance and risk related benefits • Improving Equity and Addressing Spiritual Values • Educational enrichment as an aspect of greener, healthier facilities

  13. The green building insurance link

  14. There is a fundamental asymmetry between the time scales that the climate system reacts to increases in greenhouse gases and the time scales to recover from such increases. Even if we Stop CO2 Emissions Now, Stabilization will Require Several 100 Years

  15. New World Trade Center Buildings all LEED • Security • Global Warming • Choice of Standard

  16. LEED and the 2030 Challenge • Ashrae 90.1 • Minimum energy efficiency • Green Power • Location • Leveraging USGBC/LEED and 30,000 LEED Accredited Professionals

  17. Typical home or business application Ice-Bear™ Cooling Energy Storage • Eliminates ~9kW of on-peak demand • Stores ~ 50kW-hr of off-peak energy • Shifts 93% of consumption to off-peak • Saves annual site energy (kW-hours) 010% to 25%(in typical application) • 110 units cut ~1MW of on-peak demand and ~1GW-hour of on-peak energy

  18. Way Station • Annual Energy Cost $1.49 $.46
