How Raters Label and Report Indoor airPLUS Qualified Homes

  1. Read the Indoor airPLUS Construction Specifications.
  2. Use the Indoor airPLUS Checklist to verify homes.

    Use the Indoor airPLUS Verification Checklist of the Construction Specifications or download the separate Verification Checklist to verify that homes comply with all requirements. As your builders construct homes meeting Indoor airPLUS requirements, schedule the required site visits. You can do the verification in the same 2 inspections required for ENERGY STAR (i.e., pre-drywall and final), but some of the items on the Indoor airPLUS checklist may have to be verified by the builder – for example, foundation and material selection specifications. Any item on the checklist that has both a builder and a rater verification box can be verified by either one. It's up to you and your client to determine who will check these items. Both you and the builder sign the completed checklist.

  3. Label Verified Homes

    When the checklist is completed and signed, place the Indoor airPLUS label above the ENERGY STAR label, usually on the home utility panel. HERS Providers obtain Indoor airPLUS labels from EPA through the Indoor airPLUS reporting process (see Step 5 below).

  4. File documentation with HERS Provider

    File completed Indoor airPLUS checklists with the rating files for each qualified home, following the filing requirements of your HERS Provider. Keep Indoor airPLUS checklists with the completed:

  5. HERS Provider reports Indoor airPLUS homes through HOST (Homes Online Submission Tool)

    Your HERS Provider can report Indoor airPLUS qualified homes for each participating builder to EPA via the ENERGY STAR reporting process if they are an ENERGY STAR partner. During each reporting period (January, April, July and October), HERS Providers can report ENERGY STAR and Indoor airPLUS homes to EPA on behalf of their builders and Raters through the ENERGY STAR Homes Online Submission Tool (HOST) available.

    Within the report, Providers will specify:

    • Builder name
    • Rater name (if different from Provider)IAP Label
    • Verification date
    • Number of homes that earned the Indoor airPLUS label in addition to ENERGY STAR.

    Blank label stickers can be ordered through HOST for both Indoor airPLUS and ENERGY STAR once the home reports are submitted. An Indoor airPLUS label printing tool is available for Providers to customize and print sticker labels, certificates and homebuyer letters.
    If you are not currently an ENERGY STAR partner or have questions about the reporting process, please contact Indoor airPLUS (
