The Flexible Residential Test Facility (FRTF) consists of two heavily instrumented identical side-by-side homes in Cocoa Florida with simulated occupancy. The homes are being used to evaluate a variety of envelope and energy systems improvements to homes in a hot humid climate. Similar to older building stock, both homes are poorly insulated without wall insulation, with R-19 insulation in the ceiling, and single glazed windows. Building energy simulations suggest that extensive retrofits can achieve 30-50% of energy use in such homes. However, many interactions are poorly understood. The FRTF will be used for verify energy savings and interactions under realistic test conditions in Florida's hot and humid climate. With over 5 million homes constructed in the state before 1975, such verified strategies may offer significant potential for energy and cost reductions for Florida homeowners.
