How to reduce energy consumption in buildings
Is your company based in Montréal or do you own a building there? Find out how to improve the environmental performance of buildings and learn now the city is transforming its building stock by using renewable energies and improving energy efficiency.
Building and renovating greener
Buildings are the largest source of greenhouse gas (GHG) emissions in Montréal, after transportation. From the choice of materials to the energy used for heating and the quality of the building envelope, there are several ways to reduce the environmental footprint of Montréal’s real estate stock.
What you can do as a company
All companies, small, medium or large, can take action to reduce GHG emissions and improve the energy efficiency of their buildings. If you are a business owner, you can:
- Convert your heating system to hydroelectricity, a renewable energy source from Québec that produces 100 times less GHG emissions than natural gas.
- Recommend the installation of heat pumps, which are much more efficient and therefore less expensive to operate than electric baseboards for heating, in addition to making occupants more comfortable during the summer.
- Dispose of refrigeration/air conditioning units that are at the end of their life in a responsible manner. Just visit the companies section of the RECYC-QUÉBEC site for more information (in French).
- Use LED bulbs (more sustainable and less energy intensive). Your company will reduce its energy consumption and save on its electricity bill.
- Turning off your computers and electronics completely when they are not in use can reduce their annual electricity consumption by up to 40%.
- Consider bioclimatic energy sources such as solar heating and promote natural ventilation and lighting.
What you can do as a home or building owner
You can also take action at home to protect the environment, such as:
- Replace your oil or natural gas heating system with a new efficient electric heating system. An electric system pollutes 160 times less than an oil system. You could benefit from financial assistance under the Chauffez vert program. In addition, the city will support lower-income households who want to replace their oil heating system.
- Renovate ecologically by insulating your home well. You will emit fewer GHGs and save on heating. For example, choosing EnergyStar-certified windows and optimal caulking (in French) will offer you year-round thermal comfort.
- These windows can also optimize natural ventilation in summer and help you to maximize your natural lighting, which will reduce your energy bills.

Join a dynamic Hydro-Québec pricing program, which will allow you to save money while minimizing consumption during peak periods. - Introducing solar shutter equipment (blinds) will allow you to improve the heating of your home in the winter while keeping it cool in the summer.
- Turn off your electronic devices (computers, TV, etc.). Even when they are on standby, these devices consume energy. Unplug them: You can save up to 10% on your electricity bill.
- Discover Chauffermieux.com, an online platform that guides you to the best heating solution for your home when your current system is nearing the end of its life or you are considering renovations.
The city’s commitments
There are about 500,000 buildings in Montréal. The potential for reducing energy consumption and GHG emissions is huge. The city itself owns 1,250 of these buildings. More specifically, the city undertakes to:
- Replace the use of fossil fuels (such as fossil natural gas, fuel oil and propane) in municipal buildings with renewable energy
- Regulate GHG emissions from all buildings in the agglomeration, (starting with the largest, under the By-law concerning GHG emission disclosures and ratings of large buildings.
- Improving energy efficiency by-laws and promoting sustainable building construction
- Continue to support green renovations through funding programs for building owners
