This document contains data from a study comparing classroom temperatures with and without PCM CoolZone ceiling tiles. The classroom with the PCM tiles showed consistently lower peak temperatures over the summer of 2013. Thermal modeling also showed that a classroom failed to pass thermal comfort standards without PCM tiles but passed when fitted with 20sqm of PCM tiles. Data from other schools demonstrated energy savings of up to 160 kWh/m2/yr from using PCM materials.
