Abstract

The U.S. Department of Energy (DOE) Building America program, in collaboration with Florida Power & Light (FPL), is conducting a phased residential energy-efficiency retrofit program. This research seeks to establish impacts on annual energy and peak energy reductions from the technologies applied at two levels of retrofit ' shallow and deep, with savings levels approaching the Building America program goals of reducing whole-house energy use by 40%. Under the Phased Deep Retrofit (PDR) project, we have installed phased, energy-efficiency retrofits in a sample of 56 existing, all-electric homes. End-use savings and economic evaluation results from the phased measure packages and single measures are summarized in this report. Project results will be of interest to utility program designers, weatherization evaluators, and the housing remodel industry.Shallow retrofits were conducted in all homes from March to June 2013. The energy reduction measures for this phase were chosen based on ease of installation, targeting lighting (CFLs and LED lamps), domestic hot water (wraps and showerheads), refrigeration (cleaning of coils), pool pump (reduction of operating hours), and the home entertainment center ('smart plugs'). Deep retrofits were conducted on a subset of ten PDR homes from May 2013 through March 2014. Measures associated with the deep phase of the project included replacement of air source heat pumps, duct repair, and substitution of learning thermostats. To reduce water heating energy, heat pump water heaters were installed. Pool pumps were changed to variable-speed units, and ceiling insulation was augmented where deficient. Major appliances such as refrigerators and dishwashers were replaced where they were old and inefficient.
