Under the Hood: The Working Parts of Indoor airPLUS-Existing Homes

Aaron Johnson - Indoor airPLUS-Existing Homes

US EPA, Washington, DC

About this program:

Indoor airPLUS builder and rater partners have labeled tens of thousands of new Indoor airPLUS homes over the last decade, but the program has grown most in the last 3-4 years as indoor air quality (IAQ) has become an increasing concern for Americans. With Version 2, the program intends to create specifications that will open up a pathway for certification and IAQ improvements in the millions of existing homes that desperately need the attention of home performance contractors and building science experts. EPA recognizes this as a challenging, but important step for the program. It’s a challenge to just determine what qualifies as an eligible, “existing” home! Further, the design and materials that go into a new home can be prescribed and implemented “from the ground up”- which simply can’t be done for an existing home.

 

The EPA is carefully assembling the requirements for Indoor airPLUS-Existing Homes (IAP-X).  The proposed certification model is similar to the structure of Indoor airPLUS-New Construction, but every step must:

 

• Be achievable for an existing home;

 

• Result in cost effective improvements or protections of the home’s indoor air quality;

 

• Based on best practices in building science.

Sometimes the requirement in the certification checklist needs more explanation than a sentence or a bullet or two. This session will introduce the proposed program requirements, defining what will likely be required of an evaluator, contractor, and/or homeowner participating in the process to earn the IAP-X label.
