What are the requirements to build an Indoor airPLUS home?

A home must first be designed to earn the ENERGY STAR Certified Home label, the government-backed symbol for energy efficiency. By adding additional home design and construction features, an Indoor airPLUS certified home also helps protect residents from issues like radon, carbon monoxide and mold. The home is then inspected and verified by an independent third-party to comply with the program requirements. The Indoor airPLUS verification process is integrated with ENERGY STAR processes, minimizing the need for additional inspection services.
