Building homes that use less energy

The idea of not wanting to heat the whole neighborhood isn’t new. But what if, even before buying a home, you could find out whether it lets heat escape? Many Quebecers suggested the idea of an energy rating that could be used to assess a building’s energy efficiency. This type of approach would raise construction standards throughout Québec.

A Hydro-Québec initiative

Making an informed decision

What is the electricity bill of the property that’s caught your eye? How does it compare to similar properties?

To help you make an informed decision, the Hydro Lab is working on a pilot project that would lead to electricity consumption estimates for properties available on real estate platforms.

The pilot project is not only for property buyers. People selling their home could also use the information to improve their property’s energy efficiency. The goal: to make their home more energy-efficient before putting it on the market.
