WASHINGTON — Large plate glass windows are a standard feature in many coin laundries today, so the findings of a recent study about energy-savings construction may be of interest to owners and operators.
A comprehensive analysis of window film found it to be the most cost-effective energy-saving choice for Californians when used in retrofit applications on homes and businesses, according to the International Window Film Association (IWFA).
“Without a doubt, window film offers an enormous potential for energy savings in the California market in all retrofit remodeling applications,” says Darrell Smith, IWFA executive director. “When widely installed, the resulting reduction of peak demand on utilities and greenhouse gases will further the state’s reputation as an environmental leader.”
California-based ConSol’s independent analysis compared installing window film to other traditional energy-saving techniques such as updating HVAC systems, air sealing and caulking, and adding R-38 ceiling insulation. The group used many of the same processes that the California Energy Commission utilizes in determining energy savings.
In existing commercial structures, window film’s energy savings alone can offer a payback of less than two years, or up to a 70% return on investment depending on the construction, location and window film used, according to the study.
Window film offers the opportunity to lower air conditioning costs and save on lighting bills by reducing solar heat gain, while letting in natural light without the negative impact of harsh glare and UV exposure.
