Tools and Materials for Zero Net Energy California Buildings

This project researched new phase change materials (PCM) to store thermal energy for wall assemblies, and develop associated software tools. Heat is absorbed or released when the materials change from solid to liquid or vice versa. PCMs absorb thermal energy and they can reduce the need for heating and cooling in some buildings. Their impact is similar to that of adding thermal mass to the building. Unlike air conditioning systems, they require no maintenance. The use of PCMs and associated software tools can contribute to zero net energy commercial buildings by reducing the energy needs of a building through passive design.
