3. Choose the right product for your climate zone.
Products receive ENERGY STAR® certification based on their energy rating (ER). The higher the ER, the more energy-efficient the product. Once you know which climate zone you live in, choose a product with an appropriate ER value.
Climate zone 2: ER of 29 or higher
Climate zone 3: ER of 34 or higher
The ER also makes comparison shopping easier. The ER value is calculated using a formula that balances a product’s rate of heat transfer with its potential solar heat gain coefficient and its airtightness.
Have windows and patio doors installed by a specialist to prevent heat loss and air leakage around the frames. Some retailers offer installation services.
RénoVert refundable tax credit
This temporary tax credit was introduced to encourage individuals to carry out eco-friendly home renovations that are known to have a positive impact on the home’s energy consumption or on the environment.
The period of eligibility for the RénoVert tax credit has been extended to March 31, 2018, for all recognized work other than work related to the construction, renovation, modification or rebuilding of a system for the discharge, collection and disposal of waste water, toilet effluents or gray water in accordance with the requirements set out in the Regulation respecting waste water disposal systems for isolated dwellings. As of April 1, 2017, such work has been covered by the new refundable tax credit for the upgrading of residential waste water treatment systems.
New houses often have many big windows and patio doors. As a homeowner, it’s in your best interest to choose energy-efficient products. If you’re having a house built, ask for ENERGY STAR® certified windows and patio doors. Have the contractor call in a specialist to install them so as to keep heat loss and air leakage around the frames to a minimum. Most window retailers offer installation services.
In addition to saving on heating costs, you’ll enjoy greater comfort, thanks to the energy-efficient features of ENERGY STAR® certified windows.
Low-emissivity (low-e) coatings, along with insulated frames and warm-edge spacers, minimize heat loss around your windows and reduce condensation.
Many triple-glazed models muffle outside noise as well as saving energy.
Inert gases like argon and krypton between the panes provide better insulation than the air used in regular windows.
Are ENERGY STAR® certified windows more expensive?
ENERGY STAR® certified windows don’t necessarily cost more than others. And if they do, the money you save on heating should quickly cover the extra cost. In addition, ENERGY STAR® certified windows and patio doors can help increase the resale value of your home.
Please note that Hydro-Québec does not offer cash rebates on the purchase of ENERGY STAR® certified windows and patio doors.
ENERGY STAR ®promise
As it says on the Natural Resources Canada site, all ENERGY STAR® certified products are tested to strict efficiency standards and are certified by an independent third party.
Did you know?
Heating costs account for over 50% of your electricity bill.
Up to 25% of a home’s heat losses take place through and around windows and patio doors.
ENERGY STAR® certified windows are 20% to 40% more efficient than conventional models.
What should you do with your old windows and patio doors?
Ask your municipality or your regional county municipality (RCM) about curbside recycling and bulky item pickup, waste sorting and recovery centers, or ecocenters.
