Indoor airPLUS Program

Why design and build with Indoor airPLUS? EPA created Indoor airPLUS to help builders meet the growing consumer preference for homes with improved indoor air quality. By constructing homes that meet EPA's stringent specifications, forward-thinking builders can distinguish themselves by being among the first to offer homes designed to deliver improved indoor air quality.

Homebuyers today are increasingly concerned about the indoor air quality of their homes. Issues like mold, radon, carbon monoxide and toxic chemicals have received greater attention than ever as poor indoor air quality has been linked to a host of health problems. Builders can employ a variety of construction practices and technologies in their new homes to help address these concerns.

Please remember that to participate in the IAP Program, the home must also be built to ENERGY STAR. The IAP Program is in conjunction ENERGY STAR, and the IAP checklist does replace the Water Management Builder Checklist of the ENERGY STAR home and this checklist is completed by the Rater.

To earn the ENERGY STAR, a home must meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes.

A home must first be designed to earn the ENERGY STAR label the government-backed symbol for energy efficiency. By adding up to 30 additional home design and construction features, an Indoor airPLUS qualified home helps protect residents from issues like mold, moisture and radon.

Verification can be completed within the ENERGY STAR inspection process. Instructions for Indoor airPLUS verification are included on the back page of the Verification Checklist. EPA does not verify or certify homes.
