In the previous report, the effect on the indoor environment and the improvement method when the heat capacity was increased in winter were clarified for the experimental building "House of LOHAS 3" constructed on the Koriyama campus of Nihon University. Furthermore, t the influence of the difference in heat capacity in summer and the influence of the temperature of the regenerator and the ambient temperature on the room temperature were clarified by using the "variable heat capacity system". The annual cooling load was reduced to 0 by securing the heat capacity and introducing the outside air at night. Furthermore, the measured results also showed a decrease in room temperature due to an increase in heat capacity. In addition, by using a variable heat capacity system, it is expected that the cold storage effect during the daytime and the ambient air introduction effect due to the small heat capacity at night will be reduced at room temperature.
