Thermal storage in building mass for cooling, which stores thermal energy in building thermal mass, has been reported to bring changes in indoor thermal environment such as the improvement of radiative environment and the ascent of humidity. The field measurement in a building in Tokyo showed that the tendency of the humidity ascent. Several cases of simulation are conducted to study the effect of the storage hours on the degree of the ascent. The study shows that the more the humidity ascent is, the longer the storage hours are. Countermeasures are necessary to keep good thermal environment and to meet the legal regulation in Japan. The effect of two measures is compared: 1. decrease of the minimum air flow rate of variable air volume system, 2. independent treatment of outdoor air. The former might bring the humidity ascent when the indoor thermal load is small. Control parameters of AHU for outdoor air should be set appropriately for the latter.
