What is the difference between an energy audit and a rating?
An energy rating is an energy audit that is done in a prescribed and consistent way. An energy rating will produce nearly identical results regardless of who does the analysis. RESNET has established a standard that defines the qualifications and skills the rater must have, what features and energy uses in the house are analyzed, and what software can be used. Consistency is required because ratings can be used to help secure an energy efficient mortgage (EEM), an Energy Star label, or the IRS builder tax credit.
