Work continues on effort to add PCM products to California energy code

Ben Welter - Friday, March 16, 2018

At its meeting earlier this month, the RAL Quality Association PCM discussed an update on an initiative to include phase change material in the Building Efficiency Standards contained in the California Code of Regulations.

The update, provided by Jeremiah Crossett, chief technology officer of NRGsim Inc., outlined the initiative’s timeline and cost projections.

Crossett is developing a database of PCM products and performing a detailed modeling study on a variety of PCM products in all California climate zones. The goal is to build a persuasive case for including PCMs in the next version of the standards, to be published in 2019.

Manufacturers of PCM building products are invited to submit products to Crossett for inclusion in the database. One or two products can be submitted for $2,000; an unlimited number can be submitted for $5,000. For Crossett’s modeling study, $2,000 covers one or two products; $5,000 covers an unlimited number.

Crossett hopes to complete work on the initiative by next winter. He said Insolcorp, which installs PCM building products in California, Nevada and other states, has been covering the costs. He asked if any members of the RAL Quality Association PCM would be interested in co-funding the initiative. Members suggested that the new PCM Industry Association of North America would be a better audience for that question. Companies interested in participating can contact Crossett at jcrossett@nrgsim.com.
