Picture of the FSEC Flexible Residential Test Facility.The Flexible Residential Test Facility (FRTF) offers two side-by-side 32x48 (1536 square foot) homes for conducting residential scale experiments of one envelope or equipment technology versus another.

The facility was constructed representative of older Florida homes with concrete block walls without insulation, single-pane windows and only R-19 ceiling insulation. Such configuration is ideal for any retrofit technology performance.
