What is a “deep energy retrofit”?

A deep energy retrofit (DER) is a home renovation that reduces your home’s energy usage by at least 50 per cent.
A deep retrofit involves a strategic series of steps that helps improve your home's energy efficiency and reduces greenhouse gas (GHG) emissions! A deep energy retrofit project can be done all at once or step by step over several years, depending on your unique situation, needs, and the characteristics of your home.

Progress Report #1

November 2023


"Canada’s 2030 Emissions Reduction Plan includes a target of a 40% reduction in greenhouse gas (GHG) emissions by 2030
and a goal of net-zero by 2050. 
Buildings emissions increased from 2005 to 2019 but low-rise residential emissions
actually decreased 6.1%. We are making progress towards net-zero in housing but not fast enough."
