The Impact on Energy Use and Peak Demand can be significant. Awnings have advantages that contribute to more sustainable
buildings. Awnings result in energy savings by reducing direct solar gain through windows, making your home naturally cooler and more comfortable while lightening your air conditioning load. This also directly reduces the impact of global warming from greenhouse gas emissions.


Peak electricity demand is reduced by awnings which potentially results in reduced mechanical equipment costs.

Reduced peak demand may also result in energy cost savings in the future if residential customers are charged higher rates during peak periods. Another outcome of peak demand reduction is the overall savings to utility companies and the public from a decreased need to build new generating capacity.

Cooling Energy Savings and Peak Demand Reduction

Tables 1 and 2 show the impact of awnings on reducing cooling energy and peak demand in twelve U.S. cities with different climates. The cities are listed starting with the lowest cooling energy use (Seattle) up to the highest (Phoenix). For each city, results are shown for two typical houses. The first house has windows equally distributed on all four orientations while the second house has 80 percent of the windows facing west (the case with the highest cooling energy use from heat gain). The results in Tables 1 and 2 represent the best case for savings when awnings are applied to clear double-glazed windows and operated seasonally (details appear in the full report).

Just wanted to let you know that I love my new awning – it looks great and with the rain this past week it really came in handy! Thanks for the prompt and courteous service.

We are extremely pleased with the awnings and the honest, courteous staff of Lester Awnings and Tent Rentals.

Mrs. Barabara J., Peterborough, Ont.

I’ve meant to write and thank-you again for the retractable awning you installed at our cottage on Eagle Lake. It’s absolutely wonderful – your installers were very pleasant and efficient as well.

This letter is long over due, We are the people who brought our trailer to you in June 2007 and although you were very busy, you agreed to make a new canvas and cover for it. I want to thank-you very much for doing this for us, especially when I know it put you under pressure time wise, as we wanted it for camping in July. It took a professional to do it and I was much impressed with the sewing and measurements. It smells so clean and new. It was a pleasure talking to you on the phone and also working with professionals as you people are.
