Windows and Walls

Look to windows and walls for energy savings

In the average electrically heated home, space heating costs can account for 60% of the total electricity costs. So it's worth paying attention to your windows and walls to keep heat in during winter, and cool air in during summer.

If you are replacing or adding windows, take time to research the selection available to you. Look for the Energy Rating (ER), a rating system developed by the Canadian Standards Association (CSA) together with various energy utilities. The rating takes into account the size of the window, the performance of the glazing, the frame construction, and the spacers.

Even if you're not looking at new windows, take a good look around your existing windows, doors, electrical outlets and switches, basement sill plate, and the attic for places you can improve the energy efficiency of your home's outer envelope.

It has been proven that a thorough caulking and weatherstripping job can cut between 10 - 25% from the heating bill of a house and provide a much more comfortable living environment. And it's such a natural DIY job, that nearly anyone can do it well. Have a look at the caulking and weatherstripping checklist for ideas you can use today.
