EPA Indoor airPLUS
The U.S. Environmental Protection Agency (EPA) Indoor airPLUS checklist provides links to technical guides that align with measures included in the EPA Indoor airPLUS program requirements. The numbers and titles included in this checklist follow the same order and numbering as those in the EPA Indoor airPLUS Verification Checklist. Completing these requirements fulfills the "Indoor Air Quality" section of the DOE Zero Energy Ready Home Program. To view the full program requirements see EPA's Construction Specifications document or the Indoor airPLUS website. Portions of the programmatic footnotes have been added to the Scope tabs in the guides. For additional DOE Zero Energy Ready Home program requirements and information, visit the DOE Zero Energy Ready Home Website.
