  1. Green Buildings Components Legislation LEED Emma Hetnar, Catherine Kendig, Katie O’Neill, Joe Marhamati

  2. Green Roofs • Reduce heating a cooling loads • Reduce urban heat island effect • Reduce water run-off • Provide outdoor space for building users • Clean air • Habitat space www.countyflatroofing.com www.inhabitat.com

  3. Renewable Energy and Energy Efficiency www.nytimes.com www.caseelectricalservices.co.uk www.taylorgift.com www.energystar.gov www.lcv.org www.southface.org www.energystar.gov www.southface.org

  4. Material Waste and Pollution • Indoor air is 3x more polluted than outdoor air • Concrete, lumber, cabinets removed to be reused • Can be more economical to reuse materials www.nelsonaggregate.com/ www.co.contra-costa.ca.us www.environmentalhomecenter.com www.sunbrite.biz

  5. Water Saving Devices • Rain barrels and cisterns • Gray water • Low volume flush toilets • Dual flush toilets • Permeable surfaces www.soil.ncsu.edu www.ec.gc.ca

  6. Office Buildings • Office Buildings consume more energy than any other type of building. • Out of the 100 quadrillion BTUs of energy consumed in the US, 1.0 quadrillion BTUs are used by office buildings alone. www.eia.doe.gov

  7. In the US, Buildings account for: • 65% of electricity consumption • 36% of energy use • 30% of greenhouse gas emissions • 30% of raw materials use • 30% of waste output (136 million tons annually) • 12% of potable water consumption

  8. What are the benefits? • Buildings use twice as much energy as cars and trucks • Buildings account for 1/3 of total U.S. CO2 emissions and 1/2 of its SO2 emissions • 2% additional cost results in savings of up to 20% in energy www.sustainablecommunities.fcm.ca

  9. Green Building Act 2006 • Washington is first major city to require private developers to adhere to the standards of the U.S. Green Building Council. • District to open the nation’s first green-certified stadium.

  10. Who is charge of Green Building Legislation? • Intergovernmental Green Building Group (IGBP) of the Metropolitan Washington Council of Governments (COG)

  11. What is included in Green Building Act? • Revision of Construction Codes • All new construction or significant rehabilitation of Public buildings which were initially funded in the FY 2008 District budget or later • All new Private construction or significant rehabilitation of building 50,000 square feet of gross floor area or more, built in the District as of on January 1, 2012, or later must meet standards

  12. Green Building Act cont. • Buildings required to be verified as having fulfilled or exceeded green building requirements within two years after Certificate of Occupancy • All non-residential buildings fulfilled or exceeded LEED standard • All educational facilities fulfilled or exceeded the LEED for Schools standard, or an equivalent standard • All residential buildings fulfill the Green Communities 2006 standard, or a substantially equivalent standard.

  13. Incentives • Incentive program to promote early adoption of green building practices by applicants for permits for private residential and non-residential buildings. • funded by Green Building Fund

  14. Green Building Advisory Council (GBAC) • Monitoring District’s compliance with the requirements of GBA and making policy recommendations designed to continually improve GBA • Policy recommendations to improve the District’s green building legislation • Evaluation of effectiveness of green building policies and impact on District’s environmental health and specific environmental challenges • Determine which green building practices should be included in the biennial revisions of the Construction code • Promotion of green building education • District employees • Building community • Public

  15. Leadership in Energy & Environmental Design LEED Existing Buildings: Operation & Maintenance

  16. Why become certified? • Improve building performance • Reduce building operations • Reduce environmental impacts • Healthier and more productive workplace • Ensures building is meeting potential

  17. Project Checklist 76 • Sustainable Sites 15 • Water Efficiency 5 • Energy & Atmosphere 23 • Materials & Resources 16 • Indoor Environmental Quality 22 • Innovation in Upgrades, Operations and Maintenance 5 • Total 86

  18. Rating System • Certified 32-39 points • Silver 40-47 points • Gold 48-63 points • Platinum 64-85 points

  19. Case Studies in LEED The Solaire | Blair Towns | NRDC Santa Monica | OHSU's Center for Health and Healing

  20. Land Use Challenge Constructing in outlying areas swallows land, requires new infrastructure and increases car usage, but keeping near a central location conserves land and energy. Office amenities can alter commuting patterns still more by making walking and biking more convenient. However, concentrating buildings in urban can also trap heat, something that green buildings effectively tackle. -NRDC
