Guidance for Completing the Indoor airPLUS Verification Checklist:
1. Only ENERGY STAR qualified homes verified to comply with these specifications can
earn the Indoor airPLUS label. See Indoor airPLUS Construction Specifications for
full descriptions of the requirements, terms, exceptions, abbreviations, references,
and climate map used in this checklist. Verification is not complete until this
checklist is completed in full and signed.
2. Check one box per line. Check “N/A” for specifications that do not apply for
specific conditions (e.g., climate) according to the Exceptions described in the Indoor
airPLUS Construction Specifications. Check either “Builder” or “Rater” for all other
items to indicate who verified each item. Items may be verified visually on site during
construction, by reviewing photographs taken during construction, by checking
documentation, or through equivalent methods as appropriate. If using a performance
testing alternative to meet requirement 4.2 or 4.4, the box marked “Tested” must be
checked and testing documentation must be provided in the Home Energy Rating
System/Builder Option Package (HERS/BOP) file.
3. The rater who conducted the verification, or a responsible party from the rater’s
company, must sign the completed verification checklist. The builder must sign the
checklist if any items in the “Builder” column are checked, and by so doing accepts full
responsibility for verifying that those items meet Indoor airPLUS requirements.
4. The builder provides one copy of the completed and signed checklist for the buyer.
The HERS/BOP provider or rater files a copy with HERS/BOP and ENERGY STAR documentation
e.g., Thermal Bypass Checklist) for the home.
5. The checklist may be completed for a batch of homes using a RESNET-approved sampling
protocol when qualifying homes as ENERGY STAR. For example, if the approved sampling
protocol requires rating one in seven homes, then the checklist will be completed for
the one home that was rated.
Note: The Indoor airPLUS Construction Specifications are designed to help improve indoor
air quality (IAQ) in new homes compared with homes built to minimum code. These measures
alone cannot prevent all IAQ problems; occupant behavior is also important. For example,
smoking indoors would negatively impact a home’s IAQ and the performance of the
specified Indoor airPLUS measures.
Notes:

Qualified homes earn the
Indoor airPLUS label.
Place it next to the
ENERGY STAR label.
All Indoor airPLUS qualified homes meet strict
guidelines for energy efficiency set by ENERGY STAR,
the nationally-recognized symbol for energy efficiency.
