Envelope thermal performance requirements are becoming more stringent and the most common compliance approach is to add more insulation. In many cases this may not be practical due to space constraints and greater use of glazing façade systems. An alternative approach is to increase building envelope’s thermal storage capacity by incorporating Phase Change Materials. PCMs are innovative products able to store and release large quantities of heat per unit of mass through a phase change from liquid to solid and back near typical room temperatures. The idea is that PCM absorbs part of a building’s heat load during the daytime as it melts and releases this heat during the cooler night-time by returning to its solid phase. In the summer, the released heat would be flushed out using natural ventilation or fans, while in the winter it would reduce the heating requirements.

信封热性能要求变得越来越严格，最常见的合规性方法是增加隔热层。在许多情况下，由于空间限制和更大的使用玻璃外观系统的使用可能是不实际的。另一种方法是通过增加相变材料来增加构建信封的热存储能力。 PCM是能够通过从液体到固体的相变和典型的房间温度来存储和释放每单位质量热量的创新产品。这个想法是，PCM在白天会吸收建筑物的一部分热量，因为它可以通过返回其固体阶段在凉爽的夜间融化并释放这种热量。在夏天，释放的热量将使用自然通风或风扇冲洗，而在冬季，将减少加热要求。
