The methodology provides policymakers with an estimate of the economic benefits of energy codes though a life-cycle cost assessment over a 30-year period, based on a set of parameters typical for an average mortgage. The assessment includes both single-family and multifamily buildings, as well as a variety of common building foundation and fuel types. Costs of efficiency measures are derived from the Energy Department’s Residential Cost Database and balanced against energy cost savings, mortgage payments, and other financing impacts over the life of the home.
