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
Impact of the Built Environment
Mission:
• to transform the way buildings and communities are designed, built and operated, enabling an environmentally and socially responsible, healthy, and prosperous environment that improves the quality of life.

Sustainable Sites
Sustainable Sites
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
transportation
Sustainable Sites
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
protect or restore habitat
Water Efficiency
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
wastewater
Energy & Atmosphere
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
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
optimize energy performance
Energy Supply Options Hierarchy
0 Reduce site energy use through low-energy building technologies
Daylighting, high-efficiency HVAC equipment, natural ventilation, evaporative cooling, etc.
1 Use renewable energy sources within the building footprint
Photovoltaics (PV), solar hot water, wind
2 Use renewable energy sources on-site
PV, solar hot water, low-impact hydro, wind
3 Use renewable energy sources off-site to generate energy on-site
Biomass; wood pellets; ethanol, biodiesel or waste streams that can be imported from off-site
4 Purchase off-site renewable energy sources
Utility-based wind, PV, emissions credits or other green purchasing options
Energy & Atmosphereon-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
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
refrigerant management
Materials & Resources
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
certified wood
Indoor Environmental QualityIntent:
Reduce harmful contaminants released by many materials
Adhesives & sealants (GreenSeal standard)
Paints/stains (low VOC) Flooring (Green Label,
Floor Score) Composite wood (no urea
