BioPCM™ uses the power of phase change materials to actively absorb and release heat. These “phase changes” help maintain constant, comfortable building temperatures. Thanks to major break throughs in design, Phase Change Energy Solutions uses sustainably grown, harvested and produced bio-based phase change materials to reduce energy consumption and CO2 emissions. BioPCM™ is non-toxic and non-corrosive, and shifts the warmth of the day into the night and the cool of the night into the day, all the while passively holding room temperature.
