To reduce carbon emissions from buildings in the Greater Toronto and Hamilton Area (GTHA), we need to lower the energy consumption for heating and cooling. A substantial number of buildings in the region use highly inefficient, outdated electric resistance heaters for space heating – especially in multi-residential buildings. Heat pumps as ultra-efficient heating and cooling devices offer a promising technological alternative.
The Atmospheric Fund started the Pumping Energy Savings project in 2015 to identify and help remove the barriers to the widespread uptake of heat pumps in Ontario. Our research shows the energy and emissions savings potential for heat pumps for electrically heated multi-residential buildings for the first time for Ontario. Now we need action from utilities, regulators, building industry, and building owners to take action – from more demonstration projects and better incentives to capacity building and updates to the Ontario Building Code.
