Indoor Environments & Green Buildings

Policy Resource Center

Buildings account for a large share of our energy and water consumption, carbon dioxide emissions, and solid waste. The built environment also has a significant impact on health and productivity. Children and adults in the U.S. spend up to 90 percent of their time indoors, where levels of pollutants may be many times higher than outdoors—pollutants such as radon gas, mold, lead paint, combustion products, chemicals emitted by consumer products or building materials, and other contaminants drawn into buildings from outdoors. As we work to mitigate and adapt to the effects of climate change by making buildings more efficient and resilient, attention to indoor environmental quality becomes especially important.

ELI’s Indoor Environments and Green Buildings Program provides information to support the development and implementation of sound policies that address key health and environmental issues in the design, construction, operation, and maintenance of schools, homes, and other buildings.
