Cost implications of retrofit vs. replacement of manufactured housing

Abstract

This report focuses on the evaluation of both new and retrofit energy efficiency measures in electrically heated manufactured homes, located in the marine climates of Washington State. The report uses energy efficiency cost and energy use information, collected in these homes to answer the three key research questions: What is the cost/benefit of retrofitting existing pre-HUD and HUD 1976-1994 code homes? What is the cost/benefit of improving the energy efficiency of HUD 1994 homes to an equivalency of 2012 IECC and beyond ENERGYSTAR? What is the typical monthly cash flow (energy bill, mortgage or weatherization financing costs and park rental lot fees) of manufactured home occupants in the marine climate of Seattle, WA?
