Outline of Final Research Achievements

This study developed passive cooling techniques for middle-class apartments in major cities of Indonesia. First, we investigated the current conditions of their indoor thermal environments. For example, air temperatures in the old public apartments, which had the high thermal capacity and a balcony, were found to be lower compared with those in new public and private apartments, under the unoccupied conditions. Second, given an air-conditioning is used in a bedroom, we examined the means to reduce the cooling loads in the room. The result showed that the cooling load was reduced by 45% when the room volume was reduced and the inner walls were insulated. Furthermore, optimum combinations of passive cooling techniques were determined and the comprehensive passive cooling techniques were then proposed.
