Phase change materials (PCM) can be used in many ways for thermal energy storage in passive solar architecture. Candidate materials are sodium sulfate decahydrate (Glauber's salt), calcium chloride hexahydrate, and paraffin wax. Applications include direct gain, Trombe walls, and day/night heat exchange. Advantages include reduced mass and volume, better comfort maintenance, and higher solar collection efficiency. Methods include encapsulation in exposed containers, encasement in building materials, and permeation of building matierlas. State of the art is reviewed.
