Window Film Most Cost-Effective Energy Conservation Solution, Study Finds

International Window Film Association (IWFA) — yeah, I didn’t realize that existed — reported last week that “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 buildings.” Interesting.

Energy & Financial Savings

The paypack period for window film was identified to be less than two years, with up to 70% return on investment (ROI). Of course, construction details, location, and window film used have an effect on the matter and can alter the energy savings and ROI.

Window Film’s Benefits

How does wind film help? Window film reduces solar heat gain while still letting in light. As a result, it lowers residents’ and businesses’ air conditioning and lighting costs. Window film also helps to cut out glare and UV exposure.

Combine window film with some white roofs and energy-efficient appliances you’ll have a pretty rockin’ electricity bill!

The Window Film Analysis

The analysis, conducted by ConSol, “compared installing window film on existing structures in the state to other traditional energy saving techniques such as updating HVAC systems, air sealing and caulking, and adding R-38 ceiling insulation, and found that window film came out ahead.”

“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,” said Mike Hodgson, president of ConSol.

The full report can be read on the IWFA site if you’re interested in more details.
