This study investigates the use of air source heat pumps (ASHPs) in detached residential homes in cold climates. The study aims to assess if ASHPs can provide reliable heating responses in mild, cold, and very cold climate zones across Canada. Moreover, it investigates how the use of ASHPs in a warming climate will affect the energy use intensity (EUI) and greenhouse gas (GHG) emission compared to the current most-commonly adopted gas furnaces. Different systems are compared under current and future climate scenarios. Findings indicated that ASHP systems would be best suited for residential use in Vancouver (zone 5A) across different scenarios (present 1998–2014, near future 2030–2041, and far future 2056–2075) due to the milder temperatures annually. Reversely, the colder climates of Toronto and Quebec City may require supplementing sizing of the heating systems and would result in lower efficiency and high GHG due to the higher emission factors of non-electrical power demand.

Abstract
This study investigates the use of air source heat pumps (ASHPs) in detached residential homes in cold climates. The study aims to assess if ASHPs can provide reliable heating responses in mild, cold, and very cold climate zones across Canada. Moreover, it investigates how the use of ASHPs in a warming climate will affect the energy use intensity (EUI) and greenhouse gas (GHG) emission compared to the current most-commonly adopted gas furnaces. Different systems are compared under current and future climate scenarios. Findings indicated that ASHP systems would be best suited for residential use in Vancouver (zone 5A) across different scenarios (present 1998–2014, near future 2030–2041, and far future 2056–2075) due to the milder temperatures annually. Reversely, the colder climates of Toronto and Quebec City may require supplementing sizing of the heating systems and would result in lower efficiency and high GHG due to the higher emission factors of non-electrical power demand.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
