The characteristics of climate in Japan are hot and humid in summer, with cold and dry winter. For thisreason, mold growing in rooms is common during summer period. On the other hand, in winter, due tospace heating, indoor environment is over-dry as a result of low humidity.
This study presents a multi-objective optimum design method for reliable indoor humidity environmentsbased on the appropriate use of moisture-conditioning materials. In this paper, (1) a transient predictionof indoor air temperature and humidity in a model living room is developed by employing indices for thecontribution ratio of indoor climate (CRI(C)) and contribution ratio of indoor humidity (CRI(H)), and (2) anoptimal design method is developed using multi-objective genetic algorithms (MOGA) and the transientprediction above.
