Add insulation to roof, walls and basement
The more insulation a building has, the less heat it loses in the winter, and the less heat it gains in the summer. Insulation reduces both your heating bill in the winter and your air conditioning bill in the summer. Plus, a well insulated building is more comfortable.
Some spaces are easy to insulate – like an unfinished basement or an accessible attic. These you should tackle right away. If you plan to have your staff do it, here’s a helpful resource. Otherwise look for insulation contractors in the yellow pages. The Confederation Inn in Saskatoon insulated a metal EXIT door, to prevent frost buildup that was making the door hard to open. After this photo was taken they covered the styrofoam to make it fire safe and good looking.
