Save Energy With Awnings

A hundred years ago, awnings were common on hotels, office buildings, and the grandest of houses, for a very good reason: they shaded the window and kept the heat of the sun out. They fell out of favour when the preferred method of dealing with too much solar energy became the application of electrical energy through air conditioning. They were also a high-maintenance item; it probably took quite a few workers to put them up every spring on some of the bigger installations.

But what about today, when air conditioning is costly and long lasting mechanical awnings are available? The Professional Awning Manufacturers Association funded a study covering cities such as Minneapolis, Boston, Seattle, Albuquerque, and Phoenix. It found that window awnings can reduce household cooling energy by as much as 26 percent in hot climates, and 33 percent in cold climates.

We prefer third-party independent studies, but it does make sense. ::Get With Green
