According to the American Society of Heating and Air Conditioning and Air Conditioning Engineers, an awning can reduce heat gain by 55 to 65 percent on south facing windows and 72 to 77 percent on west facing windows. The European Solar Shading Organization indicates in one of its reports that solar shading products including awnings, can help users experience energy savings of up to 10 percent.
Tests have shown that the area beneath an awnings canopy can be as much as 20° cooler. Temperatures inside are cooler and air-conditioning costs are reduced.
Retractable awnings have become increasingly popular in America. Europeans have been using them for many years because energy costs more there and air-conditioning units are less common.
In fact, as environmental awareness grows in the United States and consumers increasingly try to reduce their carbon footprint, retractable awnings continue to gain favor. The Professional Awning Manufacturers
Association suggests that awnings can reduce heat build up as much a 77%, cut air-conditioning use by 25% and lower energy bills by approximately 100 hours per year.
The group also notes that retractable awnings can cut costs in every climate. It notes that Seattle and Boston or experienced significant energy consumption reduction. Seattle cut cooling energy consumption by as much as 69% and Boston cut cooling energy consumption by as much as 33%. In contrast, retractable awnings in Phoenix cut energy use by about 26%. Regardless of climate, retractable awnings can moderate indoor temperatures and cut down your carbon footprint.
To maximize energy efficiency with little effort consider the following factors when using retractable awnings:
The projection of the awning - how far it extends - will affect how much shade is provided beneath it and inside your home. Also consider the pitch or angle of shade the awning provides to block out as much sun as possible. Buying accessories like sun sensors and motors will maximize use of the awning and minimize the amount of attention it requires.
