Abstract
This research carried out by using the three materials, water holding boards for building, rooftop greening units and a high reflectorized paint.The full-scale building was used for the experiment, survey of the amount of mitigation of the energy for air conditioning and the thermal environmental improvement effect was carried out. The survey result for nine days in the fine weather day of a summer showed material surface temperature and slab surface temperature having the lowest water holding board, and becoming roof greening and the turn of a high reflectorized paint subsequently. As a result of comparing the measurement result of water holding board division and a contrast division, the direction of water holding board division always shows lower ceiling surface temperature and indoor average radiation temperature. Although there was no difference of indoor PMV under air-conditioning, the big difference appeared after the air-conditioning stop. Power consumption became large order with a contrast division, a high reflective paint division, a rooftop greening division and water holding board division. The amount of reduction became 13.4-32.1%.
