Bio-based phase change material reduced energy costs significantly in a pilot project at the Sierra Army Depot in Herlong, Calif.
The PCM, supplied by Phase Change Energy Solutions, was installed in one of two identical warehouses. The Redstone Rocket, a publication of the Army's Redstone Arsenal in Decatur, Ala., reported on the pilot project this week:
"For four months, exterior and interior temperatures in the two buildings were recorded every 15 minutes at multiple locations. The monitoring showed how temperatures fluctuated much less within the building where the PCM was installed, especially during winter months. Natural gas consumption data showed a 50 percent energy savings, proving that the heat turned on less in the building with the PCM.
" 'We have statistically significant data showing the impacts of the material on the warehouse temperatures,' Charles King with TriVector Services said. 'What’s most important though is the relationships we’ve built with Sierra, and we look forward to furthering that in the future.'
"Sierra would like to expand the current effort across multiple facilities in the future, pending the availability of funds."
