In this study, the effect of latent heat storage in room wall materials was investigated numerically with two types of simple passive solar rooms, one is a passive solar room with a Trombe wall and the other is a direct-gain one. As the thermal storage walls, a Trombe wall made of phase change material (PCM) and a wallboard (gypsum board impregnated with PCM) were used. A numerical model to calculate the transient heat transfer in the PCM walls was developed and incorporated into a CFD code developed by authors. Thermal environments and/or required energy inputs were compared quantitatively under the condition that the thermal environment of the test room is maintained comfortable with the on-off control of a subsidiary heater operations setting the target PMV±0.5. As the outdoor conditions, a standardized weather data of Sapporo City, a cold climate district in Japan, was used. Results show that the PCM is effective both in energy savings and in peak load reduction in winter heating seasons.
