Sumner County Field Validation: An Assessment of Thermal Energy Storage in Municipal Buildings in Mixed-Humid Climates

Summary

Aging U.S. buildings face challenges with energy efficiency and managing peak energy demand, especially with new electricity pricing structures. This study validated the use of thermal energy storage, specifically phase change material (PCM) tiles, in municipal buildings in Sumner County, Kansas. The application of PCM tiles in ceilings led to a nearly 12% reduction in peak cooling energy, and duct-integrated PCM experiments showed promise for broader HVAC system integration.
