Abstract

The characteristics of climate in Japan are hot and humid in summer, with cold and dry winter. For this reason, mold growing in rooms is common during summer period. On the other hand, in winter, due to space heating, indoor environment is over-dry as a result of low humidity. This situation is particularly distinctive in the well-insulated and air-tightened houses. The aim of this study was to understand the current indoor humidity environmental conditions by the means of long-term measurement data for obtaining the fundamental information to evaluate the measures to mitigate the dry or humid indoor environment. In addition, the conditions of fungal contamination influenced by indoor environment were predicted. A detailed long-term field measurement program on energy consumption and indoor thermal environment was carried out in 2003, for 80 dwellings (including detached houses and apartments) in six regions of Japan. The data obtained from the field measurement were analyzed and the results based on indoor humidity distribution were reported in this paper.
