AbstractMeasured space heating and total energy-consumption values are presented for a one-year monitoring period for a group of 27 low-energy houses in Saskatoon, Saskatchewan, Canada. The average space heating energy consumption for the 27 houses was 43.7 kJ/m.degrees C-d (2.1 Btu/ft[2].degrees F-d) for the period from May 1980 to May 1981. The total energy consumption averaged 365 MJ/m[2] (32,200 Btu/ft[2]); and space heating energy consumption averaged 228 MJ/m[2] (20, 100 Btu/ft[2]). These low-energy houses have a number of energy-conserving features -- air tightness, controlled ventilation, air-to-air heat exchangers, use of south windows for passive solar gain, and high insulation levels -- that distinguish them from conventional housing stock.
