In a new energy hypothesis given by Dr. Joe Huang, a researcher, scientist and president of the consulting group, White Box Technologies, states that awnings and exterior shades can accommodates saving on home cooling stuffs by reducing the load on air conditioners. The study obesrves the influence of awnings in 50 cities across the United States and will be provided to the public sometime onwards this summer.
According to the data analysis, in a warm year, awnings can lower down the annual cooling energy by more than 52%, as compared to the homes having completely unshaded windows. The amount of cooling energy saved differs depending on the number of windows, kind of glass in the windows, window orientation and the weather of the region. This can amount to as much $200 or more in energy savings for homes with equal window distribution having single or double pane windows.
For instance, in Fort Worth, TX, a house with awnings cooling energy use is reduced by 14-25%compared to the same house without awnings. Both cooling energy savings and the peak demand reductions are largest on homes with west-facing awnings.
“People now realize that cooling energy is lost through glass doors and windows,” said Michelle Sahlin, managing director of PAMA. “This study bolsters the fact that awnings and exterior shades are an effective method to reduce heat gain and cooling energy costs.”
The awning energy study, commissioned by the Professional Awning Manufacturers(http://www.grandawnings.com/) Association (PAMA), increased the number of variations (cities, shade designs and fabrics). White Box Technologies also incorporated updated information about weather and energy costs, and includes improvements to the simulation model.
