Buildings consume a significant amount of primary energy and a major source of greenhouse gases (GHG) emissions. Several proven technologies available for building heating/cooling differ in terms of energy saving potential, GHG emissions mitigation and dependency on fossil fuels. The successful acceptance of any new technological development depends on its efficiency, cost-effectiveness, reliability, and competitiveness with other technologies. Air Source Heat Pumps (ASHP) are considered a promising technology which can enable buildings to eliminate or minimize the use of natural gas, oil, and electricity. However, the ASHP systems has achieved a limited acceptance in Canada due to their reduced heating performance in winter season. The ASHP systems heating capacity and the coefficient of performance (COP) decrease considerably as the source (air) temperature drops below zero degree centigrade. On the other hand, solar thermal collector provides an emissions free source of heat, but cannot provide all the heating needs of buildings, especially during cold
