- Revised DOE regulations allow greater flexibility in conducting DOE-funded low-income weatherization programs. Certain retrofits to heating and cooling systems for these houses are now permitted, as well as the traditional insulation and infiltration control measures. Also, different amounts of money may be spent on different houses, as long as the average expenditure per house does not exceed $1600. The expanded list of retrofit options provides an opportunity for increased energy savings, but it also complicates the process of selecting the combination of retrofits, house-by-house, that will yield maximum savings for the weatherization program. DOE asked ORNL to devise a procedure for selecting an optimum combination of building shell and heating system retrofits for single-family dwellings. To determine the best retrofits for each house that would maximize program savings, ORNL staff members developed an approach that used information from a preretrofit energy audit of candidate houses. Audit results are used to estimate annual energy savings for various retrofits for each house. Life-cycle benefits (B) are calculated, as are the estimated installation costs (C) for given retrofits in given houses. The benefit-to-cost ratios (B/Cs) are then ranked for all possible retrofits to all candidate houses, and the top-ranking B/C retrofits are selected for installation. This process maximizes program savings, and it is adaptable to varied housing types in different climates. The Audit-Directed Retrofit Program (ADRP) was field tested in a low-income housing retrofit program in Wisconsin during the winter of 1985-86. Results of the field test are reported in a companion document. This report describes the ADRP for the benefit of potential users.
