Install awnings to keep summer heat out and let winter heat in


In winter and in summer the sun can pour a lot of heat into our buildings.  In the winter, that is great.  Let the sun in.  In the summer, that overheats our buildings or makes our air conditioning run longer.


If you are renovating, install awnings over your south windows.  Choose the size and location of the awnings to keep the summer sun out, but let the winter sun in.  Use a free on-line program like SketchUp, or your old protractor and a straight edge to figure out the best location for your awnings.  In Saskatoon, at noon on June 21, the sun is 61o from the horizon.  On Dec 21 it is 14o.
