Energy Savings for residential buildings | Sunair Awnings
You can also reduce your utility bills. Our awnings reduce sunlight and glare through your windows by up to 94% and reduce heat gain by as much as 77%.
Awnings can reduce cooling energy by as much as 17% in moderate climates.
There is a great study by the University of Minnesota and funded by the Professional Awning Manufacturers Association (PAMA) that compares the impact of awnings in twelve U.S Cities. This study was conducted by the Center for Sustainable Building Research at the University of Minnesota. This study revealed that awnings result in energy savings by reducing the direct solar gain through windows. According to the study, awnings can reduce annual cooling energy by as much as 20- 30 percent on unshaded windows in hot climates, such as Houston, and as much as 30 - 50 percent in moderate climates, such as Washington, DC, compared to homes with completely unshaded windows. The amount of cooling energy saved varies depending on the number of windows, type of glass in the windows, window orientation and the climate the house is in.
“What some people don’t realize is that in most homes, more cooling energy is lost through glass doors and windows than any other part of the house,” said Michelle Sahlin, managing director of PAMA. “Awnings are an effective way to reduce heat gain and prevent cooling energy loss in households. This benefits the environment by reducing greenhouse gas emissions and the homeowner by saving them money on energy bills.”
