Amanda Hickman, president and consultant of the Hickman Group, discussed the importance of energy codes, green codes and Home Energy Rating System (HERS) ratings.

Amanda Hickman, president and consultant of the Hickman Group, discussed the importance of energy codes, green codes and Home Energy Rating System (HERS) ratings in a seminar sponsored by the International Window Film Association (IWFA) as part of the International Window Film Conference and Tint-Off™ this week.

Building codes, regulations and utility incentive programs, as well as new energy rating systems, present a new playing field for the residential window film market, Hickman explained.

“The biggest trend is the lean towards performance,” she said. “We have our prescriptive language, now our focus, and the current trend, is toward the performance side [of products].” Performance paths then trickle down into rebate programs for retrofit options, including window film.

The HERS Index, which was developed by RESNET, is a software tool used by energy raters to calculate a home’s overall energy performance. The lower the HERS rating, the better the home’s energy efficiency.

“Window film allows for credit where prescriptive path did not allow for it,” Hickman said. “It’s more attractive to designers, architects and homeowners because it’s a more flexible path.”

Darrell Smith, executive director of the IWFA, noted that in California, window film is listed at the top of renovation load sheets. “It’s the most affordable energy efficient retrofit option,” he added, “and it’s the first thing consumers will read.”

Research shows that homeowners are more likely to choose energy efficiency options when coupled with other remodeling projects, Hickman said. “The window film industry should be connecting with renovation and green contractor associations to include window film in renovation projects,” she advised.
