Indoor airPlus
Third-party assessment for the EPA’s Indoor airPLUS program is available for any home that is earning an ENERGY STAR® certificate. The Indoor airPLUS process involves using construction practices and product specifications to reduce indoor air pollution, like features that help control mold and moisture, enhanced HVAC systems, and low-VOC or no-VOC building materials. Certified houses offer a more comfortable, healthier indoor environment.
This is a great way for builders to stand out from the competition, as well as avoid potential liability. In addition, Indoor airPLUS builders can use Indoor airPLUS marketing materials to advertise their qualified homes.

Before a home officially earns the Indoor airPLUS label, it needs to be inspected by an independent third-party to ensure compliance with the EPA’s rigorous guidelines and specifications, which is where ESG comes in.

ESG’s inspection and certification process includes:
- Completion of the Indoor airPLUS Verification Checklist to verify that homes comply with the requirements. ESG will schedule the required site visits in order to support the builder’s work in meeting the requirements.
- Placing the Indoor airPLUS label above the ENERGY STAR® label on the panel.
- Filing the completed checklists with the rating files.
- Reporting the certification to ENERGY STAR®.
