The performance of a passive solar modular house located in Knoxville, Tennessee (TECH House V) was determined for the 1981–1982 heating season. The 111 m2 (1200 ft2) house has 13.7 m2 (144 ft2) of south facing glass and 20 vertical water tubes. The auxiliary heat was measured directly while the net solar gain was calculated using hourly measured vertical insolation, weather, and inside-space temperature data. The solar collection efficiency was 64 percent and the solar fraction was 0.40.
