Impact of the Built Environment Buildings represent 39% of primary energy use in the U.S. Lighting Heating Cooling Cooling Refrigeration
Impact of the Built Environment Buildings represent 39% of primary energy use in the U.S. Buildings account for 39% of all CO2 emissions in the U.S. Buildings use over 12% of all potable water, or 15 trillion gallons per year in the U.S. Buildings use 40% of raw materials globally, or 3 billion tons annually 136 million tons of building related C&D waste was generated in a single year

Leadership in Energy and Environmental Design LEED Green Building Rating System
Sustainable Sites transportation Intent: Reduce pollution and land development impacts from automobile use • Public transportation access • Bicycle storage & changing rooms • Preferred parking for fuel efficient vehicles & carpools • Reduce parking capacity
Sustainable Sites protect or restore habitat Intent: Conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity • Restore or protect a min. of 50% (25% EBOM) of the site with native or adapted vegetation • Coordinate with integrated pest management & water use reduction for landscaping
Water Efficiency wastewater Intent: Eliminate potable water demand for conveying wastewater • Treat wastewater on-site • Use stormwater/graywater for sewage conveyance • Use high efficiency/dry fixtures • Reduce demand on infrastructure
Energy & Atmosphere commissioning Intent: Verify that the project’s energy-related systems are installed, calibrated and perform according to the owner’s project requirements, basis of design and construction documents • Cost of Fundamental Commissioning +/- $1/SF • Owner develops project requirements • Engineer develops basis of design
Energy & Atmosphere commissioning • Enhanced Commissioning includes systems manuals, training & a 10-month review • Implement an ongoing commissioning program that includes planning, system testing, performance verification, corrective action response, ongoing measurement and documentation
Energy & Atmosphere optimize energy performance Intent: Achieve increasing levels of energy performance to reduce environmental and economic impacts associated with excessive energy use • Minimum standard: ASHRAE 90.1-2007 • Up to 19 points available for 48% energy reduction
Energy & Atmosphere on-site renewable energy Intent: Encourage and recognize increasing levels of on-site renewable energy self-supply to reduce environmental and economic impacts associated with fossil fuel energy use • Photovoltaic systems • Wind energy systems • Solar thermal systems • Biofuel-based electrical systems • Wood, agricultural, organic waste; landfill gas • Geothermal heating and electrical systems • Low-impact hydroelectric power systems • Wave and tidal power systems
Energy & Atmosphere refrigerant management Intent: Reduce ozone depletion and support early compliance with the Montreal Protocol while minimizing direct contributions to climate change • Do not use refrigerants, or • Use natural refrigerants: carbon dioxide, ammonia, propane • Use refrigerants w/low ozone-depletion & global warming potential
Materials & Resources certified wood Intent: Encourage environmentally responsible forest management • Current standard: Forest Stewardship Council (FSC) • Most West Virginia forests adhere to Sustainable Forest Initiative (SFI) standard • USGBC is reviewing this credit to possibly include SFI
Indoor Environmental Quality materials Intent: Reduce harmful contaminants released by many materials • Adhesives & sealants (GreenSeal standard) • Paints/stains (low VOC) • Flooring (Green Label, Floor Score) • Composite wood (no urea formaldehyde)…remember Katrina trailers
Innovation & Design Process additional items… Intent: Be rewarded for exceptional performance above LEED requirements • Innovation • Education of the users & general public • Life cycle cost analysis
Final thoughts…. It’s not about doing less… It’s about designing better! 2008 SUSTAINABILITY
