The Impact of Requiring HVAC System Design Submittal on System Performance
Recent CMHC research has shown that heating and ventilating components (HVAC) in new Canadian houses do not perform as intended. A very small study was conducted of eight completed homes in two Alberta cities, where the municipal design and inspection routines are quite different. While the systems in the first city were marginally better, as expected, the study did not conclusively show that more stringent design submissions, at the municipal permit stage, result in better HVAC installations in houses. The small house sample contributed to this uncertainty. The field testing echoed earlier studies in showing that current HVAC installations do not meet code, and that municipal inspections do not identify the deficiencies or call for rectification.
