During the winter heating season of 2002–2003 and the summer cooling season of 2003, the Canadian Centre for Housing Technology (CCHT) ran a series of trials to determine actual energy savings from thermostat setting in one of its R-2000 test houses. The unique nature of the CCHT Twin House Facility allowed the examination of not only energy savings but also of whole-house performance. During the thermostat experiments, important factors that affect occupant comfort were explored, including air temperature recovery time from setback and setup, house surface temperatures during winter setback, solar effects, and summer house humidity, giving a broad picture of the effects of thermostat setback/setup in a typical R-2000 home.
