SBIR USEPA Region 92
Buildings in the United States have a significant impact on the environment and account for:
Energy– 37 % of primary energy use– 68 % of all electricity use
Materials– 60 % of non-food/fuel raw materials use
Waste– 40 % of non-industrial solid waste from construction and demolition debris
per year Water
– 36 billion gallons of water per day– 20 % loss of potable water in many urban systems due to leakage
Air Quality– 35 % of CO2, 49 % of SO2, 25 % of NOx, and 10 % of PM emissions
SBIR USEPA Region 93
Green Buildings and EPA
Sustainable building is a priority under EPA's Resource Conservation Challenge
EPA is an active member of the U.S. Green Building Council
Federal statutes require green building practices Agency issued Environmental Quality Guidance
for Green, High Performance and Sustainable Buildings
Buildings have tremendous human health and environmental impacts
SBIR USEPA Region 94
Environmental Impacts of Buildings
Indoor Air/Human Health– Americans spend 90% of their time indoors– On average, indoor air is 2-10 more
contaminated that outdoor air– 20% of workers suffer from indoor air
illnesses resulting in 11,400 premature deaths/year
– Health and productivity losses associated w/indoor air quality are estimated to cost tens of billions of $ annually
SBIR USEPA Region 95
Environmental Impacts of Buildings
Air/Energy Impacts– Buildings consume one third of all energy– Consume 2/3 of all electricity in the U.S.– Buildings contribute
25% of all greenhouse gas emissions, 49% of sulfur dioxide emissions, and 10% of particulate matter emissions
SBIR USEPA Region 96
Environmental Impacts of Buildings
Waste Impacts– Worldwide construction activities consume 3
billion tons of raw materials each year– Nearly 40% - 136 million tons/year - of waste
going to landfills in the US is building construction and demolition debris
– More than 30% of the mercury in solid waste is from building switches, thermostats, florescent tubes, and paints

SBIR USEPA Region 99
Federal Government Leading by Example
Owns 500,000 buildings = 3.1 billion sq. feet of floor space
Largest energy user in the country– 2% of building-related greenhouse gases in US– $3.4 billion/year– 23% reduction in energy (‘85-’01)– 100 buildings are Energy Star labeled– 10.5 million metric tons of carbon equivalent/year
SBIR USEPA Region 910
Federal Green Building Materials Requirements
Building insulation Carpet & padding Cement & concrete
containing fly ash/slag Latex paint Floor tiles Flowable fill Laminated paperboard Patio blocks
Railroad grade crossing surfaces
Restroom dividers Structural fiberboard Compost & mulch Landscaping timbers Park benches & picnic
tables Playground equipment &
surfaces
SBIR USEPA Region 911
Federal Law: RCRA 6002 and Executive Order 13101
Requires the purchase of recycled materials - Federally funded projects
Uses Federal purchasing power to promote recycling
EPA and State inspectors enforce implementation of RCRA 6002
TOOLS: – Screened vendor lists– Specifications
SBIR USEPA Region 912
Aluminum– 95% less air pollution– 97% less water pollution– One can = energy savings of ½ a
can of gasoline
Paper– 74% less air pollution– 35% less water pollution– One ton = 17 trees & 7,000 gallons
water
Green House Gases = 25 million cars/year
Why Recycled Products?
SBIR USEPA Region 913
Additional Federal Focus Areas
Energy Star Environmentally Preferable Purchasing
– Green Janitorial Products– Biobased Products (wheatboard, soy adhesives,
plastics) Construction & Demolition Debris
– Database of C&D Recyclers Green Leasing Waste Wise GreenScapes
SBIR USEPA Region 914
The Challenge
SBIR USEPA Region 915
The Challenge
Increase the efficiency with which buildings and their sites use energy, water, and materials, and
Reduce building impacts on human health and the environment, through better siting, design, construction, operation, maintenance, and removal
Assess the complete building life cycle
SBIR USEPA Region 916
Green Building requires anintegrated design approach:
Focusing on only one component of a building can have unintended environmental, social, or economic consequences
Examples:– Poorly designed energy efficient building envelopes can
result in poor indoor environmental quality– Some recycled content latex paint could have higher volatile
organic compound (VOC) emissions than other environmentally preferable paints
SBIR USEPA Region 917
Example of Green Building (1)
New GSA Federal Building in San Francisco
– windows that open, – shared spaces between
offices, – lots of natural light, – reduce energy costs by 45
percent, and– is expected to save
$500,000 per year in taxpayer dollars.
SBIR USEPA Region 918
Example of Green Building (2) - Low Tech
Earthship– 4500 used tires– Round adobe bricks
Solar Panels Sinks
– Grease & particle filter– Garden grey water
Freshwater collection– Roof/rain > 4 cisterns– 40,000 gallons
Garden “gray water”
SBIR USEPA Region 919
SBIR R&D for Green Buildings
Impacts of buildings are so tremendous Numerous research opportunities
– on buildings’ environmental effects and interactions and
– on technologies and techniques to reduce these impacts
We encourage new ideas/research
SBIR USEPA Region 920
Research Needs
Water conservation and reuse, Recharging of groundwater, Construction runoff control, Use of green building products, Indoor environmental quality (e.g., day-lighting, ventilation, low
emitting materials) Design products to consider toxicity emphasizing natural, low-emitting
materials Effect on cost savings, worker productivity, and worker health Comparable information on the environmental impacts of building
products– life cycle assessment (LCA) and– building product life cycle inventories (LCI) tools and
protocols
SBIR USEPA Region 921
Some Green Building SBIR Topics
Design techniques or equipment to promote building renovation/deconstruction instead of demolition
Design, construction practices or equipment to improve indoor air quality
Building materials development to reduce risks from persistent, bio-accumulative, and toxic (PBT) chemicals
Recycled content building materials development using local feedstock
Develop natural flame retardancy for building materials
Rapidly renewable/bio-based building materials development using local feedstock
Environmentally preferable building systems or materials with unique application to arid Southwest
Measurement/metering equipment for green building systems
Moisture control systems/materials/detection equipment for condensation, water intrusion, etc.
