Indoor Environments & Green Buildings

Policy Resource Center



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

Buildings account for a large share of our energy and water use, CO2 emissions, and solid waste. The built environment also has a significant impact on health and productivity. Children and adults in the U.S. spend an average of 90% of their time indoors, where levels of pollutants may be many times higher than outdoors—pollutants such as radon, mold, lead, combustion products, chemicals emitted by consumer products or building materials, and contaminants drawn into buildings from outside. 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.

Database of State IAQ Laws

State Law Surveys collect and describe state laws and regulations across the U.S. and are updated periodically:

*Database of State Indoor Air Quality Laws

*Topics in School Environmental Health

*Recent IAQ Policy Developments


Research Reports

Research Reports examine lessons learned from existing state and local policies and programs and offer recommendations for developing effective approaches in core areas of indoor environments and green buildings policy.

 Policy Briefs on Emerging Legislative Issues

Policy Briefs highlight important indoor environmental and green building issues that have captured the attention of state policy makers. Each Brief is updated periodically throughout the year to provide an overview of the issue and summaries of policies enacted to date.


Profiles of Innovative State Programs

Profiles of Innovative State Programs describe innovative informational resources developed by state agencies working to protect and improve indoor air quality. The Profiles highlight resources that can be adapted and used in other jurisdictions to promote healthy buildings.
