Title: Building America Case Study: Supplemental Ductless Mini-Split Heat Pump in the Hot-Humid Climate, Brevard and Volusia Counties, Florida

"The BAPIRC team and Florida Power and Light (FPL) electric utility pursued a pilot phased energy-efficiency retrofit program in Florida by creating detailed data on the energy and economic performance of two levels of retrofit - simple and deep. For this Phased Deep Retrofit (PDR) project, a total of 56 homes spread across the utility partner's territory in east central Florida, southeast Florida, and southwest Florida were instrumented between August 2012 and January 2013, and received simple pass-through retrofit measures during the period of March 2013 - June 2013. Ten of these homes received a deeper package of retrofits during August 2013 - December 2013. A full account of Phase I of this project, including detailed home details and characterization, is found in Parker et al, 2015 (currently in draft). Phase II of this project, which is the focus of this report, applied the following additional retrofit measures to select homes that received a shallow retrofit in Phase I: supplemental mini-split heat pump (MSHP) (6 homes), ducted and space coupled heat pump water heater (8 homes), exterior insulation finish system (EIFS) (1 homes), window retrofit (3 homes), smart thermostat (21 homes: 19 NESTs; 2 Lyrics), heat pump clothes dryer (8more » homes), and variable speed pool pump (5 homes).« less
