Phase change materials (PCMs) have excellent thermal energy storage (TES) potential to provide thermal comfort in buildings by lowering the cooling and heating energy demands. The primary grid benefit of thermal energy storage is load shifting and shedding by replacing heating, ventilation, and air conditioning system operation during peak times and recharging the storage system during off- peak times. Additional efficiency benefits come from shifting HVAC system operations to periods when the system can operate more efficiently and at a lower cost. This paper discusses the present state-of-the-art PCMs for thermal energy storage systems for buildings applications and some limitations to phase change materials that negatively impact the performance. Results for two available and environmentally friendly PCMs (BioPCM and DuPont Energain) with different melting ranges applied inside the exterior walls and the roof are analyzed and presented.
