Aerogel Insulation Enhanced with Phase Change Material for Energy Conservation in Structures

Energy conservation in buildings and structures can be improved by utilizing high performance aerogel insulation and Phase Change Materials (PCM) in concert. Aerogel insulation has a high R-value per inch and can be cost effectively installed in existing buildings with minimal impact and disruption. PCM are also proven to reduce energy consumption in buildings. PCM have high latent heat capacity and absorb heat at daytime when they change from solid to liquid and release the energy while solidifying as temperatures fall during evening hours. A building retrofit product that includes PCM integrated with aerogel insulation will simultaneously increase the thermal resistance and heat capacity of existing structures to conserve energy. The combination of passive aerogel insulation with active thermal disconnect elements such as PCM, reflective layers and air spacing will provide significant energy savings by reducing the need for HVAC cooling and by shifting energy peak loads from daytime towards cheaper night time. Aspen Aerogels will design, develop, and demonstrate a building retrofit product with high energy savings and minimal impact on the existing structure. This product will reduce energy consumption and peak-hour power loads. The PCM-enhanced insulation will be flexible, lightweight, easy to install, hydrophobic, fire resistant and durable.
