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

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
