IWFA Report Reveals Window Film as Most Cost-Effective Energy Saving Choice for Californians

March 8th, 2012 by Editor

 An independent analysis has revealed that window film is the most cost-effective energy saving choice for Californians when used in retrofit applications on homes and buildings. The International Window Film Association (IWFA) released the report done by ConSol, a California energy consultant firm.

The study compared the installation of window film to other energy savings measures (updating HVAC systems, air sealing and caulking, adding R-38 ceiling insulation) and concluded that the best opportunities for saving energy with window film are in existing high-rise office buildings. The study also determined that film is a more cost-effective retrofit opportunity for homes than other measures, especially in homes with single pane glass. In addition, the report states that window films “demonstrate an effective means of reducing GHG emissions when used in retrofitting existing buildings.”

“Without a doubt, window film offers an enormous potential for energy savings in the California market in all retrofit remodeling applications,” says Darrell Smith, executive director of the IWFA. “When widely installed, the resulting reduction of peak demand on utilities and greenhouse gases will further the state’s reputation as an environmental leader.”

“With over 70 percent of the buildings and homes in the California market having been constructed before 1980, window film has to be high on the list for every building retrofit project across the state,” says Mike Hodgson, president of ConSol.

ConSol conducted the study using many of the same informational processes that the California Energy Commission utilizes in determining energy savings.
