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 Indoor airPLUS Construction Specifications, Version 1 (Rev. 04 ) document. For additional DOE Zero Energy Ready Home program requirements and information, see the DOE Zero Energy Ready Home National Program Requirements (Rev. 07).
