If you are a current ENERGY STAR builder, Rater, or Provider partner, you can join the Indoor airPLUS Program by accessing the Partnership Agreement through your My ENERGY STAR Account (MESA). If you forget both your MESA login and password or you have difficulty accessing your account, contact an account manager at energystarhomes@energystar.gov for assistance.

 If you are new to both ENERGY STAR and Indoor airPLUS, you can join both programs at the same time as a builder or verification organization (Rater/Provider) by visiting the Online Partnership Agreement. Upon approval and successful activation, you will receive a welcome email from the Indoor airPLUS Team with a list of resources available to you as a partner.
