That the government recapitalize the Smart Renewables and […]
Guide to Measurement and Verification of Heat Pump Retrofits
October 2022. Government of Ontario. Space heating represents the largest energy end use in Ontario multifamily buildings at 54.6% Heat pumps can offer significant energy savings compared to traditional heating systems in multi-unit residential buildings. However, upgrading to a heat pump represents a significant capital expenditure for building owners, property managers and condo boards. Measurement […]
Lessons from a Heat Pump Retrofit at CityHousing Hamilton
May 2022. Government of Ontario. TAF collaborated with CityHousing Hamilton to plan and implement a pilot project at a three-storey multi-family residential building with 40 units. We installed a heat recovery, variable refrigerant flow (VRF) air source heat pump (ASHP) system in three suites to test the performance of the technology under real-world conditions and […]
Lessons from a heat pump retrofit at Walpole Ave: A case study
January 2021. City of Toronto. To demonstrate the viability of retrofits focused on electric heat pumps, TAF installed and monitored eight cold climate air-source heat pumps (CC-ASHPs) at 66 Walpole Avenue as a pilot project. This case study summarizes the pilot project specifics, results, and learnings.
