Awnings can help keep your home cooler. They can also reduce your air
conditioning expenses. And if your installing or replacing air conditioning equipment,
awnings will allow you to reduce the size of the equipment needed to effectively cool your
Here's how awnings do all this: Windows get to be hot spots during
warm weather. Heat pours into a home through windows in three ways: Direct sunlight
streams through windows and raises interior temperatures quickly. Indirect sunlight
reflected from the ground, sidewalks and other buildings compounds the effects of direct
sunlight. And as the direct and indirect sunlight pass through the window, the temperature
of the glass rises and radiates additional heat into the house.
Shading those windows with an awning is one of the most effective
ways of reducing solar heat gain during the hot months. Awnings block most of the direct
sunlight. They greatly reduce the amount of indirect sunlight that enters a window. And
they keep the window cooler, which reduces the heat radiated from the glass.
Studies conducted by the American Society of Heating and Air
Conditioning Engineers a few years ago confirm this. The studies found that fabric awnings
reduce heat gain by 55 to 65 percent on a southern exposure and by 72 to 77 percent on a
Savings on operating of air conditioning will pay for the awnings
in a short period of time. How soon depends on your windows, their number, type, the
amount of wall space they cover and the direction they face. Added comfort and savings
from the awnings also depend on where you live and how much your air conditioner costs to
No two homes are exactly alike. No savings figures will be the same
from one home to next.
But with decorative awnings to shade your home's windows, your home
will be cooler. Your air conditioner expenses will be less. If you are adding or replacing
air conditioning. your initial expense can be less.
