Abstract: Three National Energy Code for Buildings (NECB) 2017 archetypes models (small office, full-service restaurant, and 4-storey multi-unit residential buildings) are modified touse cold-climate air-source heat pump (CCASHP) air systems. The predicted energy consumptions using the Building Technology Assessment Platform (BTAP) of the three archetypes is lower for CCASHP systems compared to the NECB 2017 baseline. However the cost of electricity is higher than natural gas, therefore heating ventilation with a CCASHP compared to a gas-fired unit, was not cost effective. The high capital cost of CCASHP systems makes it difficult to achieve a reasonable payback period for most locations. Payback years are more attractive for locations such as Halifax where the price difference between natural gas and electricity is reduced. Net-Present Values for CCASHP systems are relatively close to the baseline for many cases, which could make these systems attractive if they can help reduce Green-House Gas (GHG) emissions.
