Replacing older manufactured homes with new, energy efficient ones can lead to significant energy savings as well as substantial non-energy benefits. The RTF has developed estimates of energy savings from replacing manufactured homes built before federal, Housing and Urban Development (HUD) standards were in place (1975 and older), and from the first generation of HUD compliant homes (1976 - 1994), with efficient new homes (EcoRated, ENERGY STAR, and NEEM 2.0).
The RTF developed savings and cost estimates to support regional conservation program interest in this measure, despite it being far from cost-effective on an energy basis alone. Conservation programs are exploring partnerships with other regional and federal funding sources that reflect the potential for energy, health, and social benefits.
Savings and cost estimates are provided in the form of a calculator, in which the user can specify the size (floor area) of the existing and new homes, the vintage of the existing home, the efficiency rating of the new home, and the heating system type of each home. Costs account for decommissioning the existing home; preparing the site for the new home; and the purchase, transportation, and installation of the new home.
The cost and savings analysis, and calculator, presented at the May 2017 RTF Meeting were approved, as presented, for planning purposes only.
