Abstract: The aim of this paper is to present the impact of air to water heat pump (AWHP) and photovoltaic (PV) retrofit on the energy consumption and greenhouse gas (GHG) emissions of the Canadian housing stock. The study is conducted using the Canadian Hybrid Residential Enduse Energy and Emission model (CHREM). CHREM is based on the Canadian Single-Detached and Double/Row Database (CSDDRD), and utilizes the high resolution building energy simulation program ESP-r as its simulation engine. A suitable AWHP and PV system architecture for existing houses in the Canadian climate is selected. A numerical model for the selected architecture is developed using the available components in ESP-r. The model is applied to the houses eligible for AWHP and PV retrofit. The impact of AWHP and PV retrofit on electricity, oil, natural gas and wood consumption as well as the associated GHG emissions is estimated for each province. The results of this study will be used to develop strategies to convert existing Canadian houses into near/net zero energy buildings.
