Did you know that according to Hydro-Quebec, heating and air conditioning alone are responsible for 54% of a home’s energy costs? This is the main reason why energy efficiency is at the center of so many conversations, subsidy programs and the focus of our building contractors. Read our article as we take a look at 3 important elements when it comes to energy efficiency in our homes.

Energy efficiency and doors and windows

Did you know that simply changing your old wooden windows for a newer energy-efficient model can reduce your heating costs by 10%, according to Hydro-Québec. Again, depending on the model and the quantity to be replaced, this can translate into savings of up to $500 directly into your pocket! An American study mentions that the use of curtains or blinds in hot weather can reduce heat gain by 45%. If you are interested in such an approach, perhaps you should opt for thermal blinds for optimal performance.

When it comes to doors, you may be surprised to learn that a modern energy-efficient fiberglass door without windows offers much greater insulation than an equivalent wood door. Even more, simply repairing or replacing the weather stripping will increase your energy efficiency substantially. Also, the low-emissivity glass offers a reduction of energy losses of about 30% compared to an equivalent standard model according to Natural Resources Canada.

Energy efficiency and the roof

A quarter of all heat loss occurs through the roof, and simply improving the insulation and airtightness of the wall between the living area and the attic can allow you to save considerably on your energy bills. Another surprising fact, an American study recently showed that, despite the fact that a white roof reflects between 70 and 80% of the sun’s energy, more than 90% of homes in North America are covered with a dark roof. Yet a typical asphalt shingle roof only reflects 30% of this energy…

Energy efficiency and walls

Hydro-Quebec identifies the walls of our homes, i.e. the roof, the walls and the floors, as being responsible for 75% of the heat loss of a house, depending on the age of the building and therefore the type and quantity of insulation present. In fact, improving the insulation of the exterior walls and foundation can bring an impressive reduction in heat loss from your home! And while you’re at it, why not improve your insulation and waterproofing at the same time. After all, air leakage and ventilation account for the other 25% of energy loss. This way, you will save even more on your heating bills and improve the comfort of your family by reducing drafts…

If you are considering doing some work or if you feel that your energy bills are too high, why not call on the services of an energy evaluator. He or she will be able to inform you about your particular situation, help you choose the work you want to do and guide you towards the subsidy programs that may apply. You will then be able to take advantage of financial assistance and save on your energy bill…
