木造ダブルスキンの熱挙動実測調査と地域別適用可能性の検討

Abstract

Double-skinneDSiding (DS) and its buffer zone on thermal environments of both new and old wooden structures found throughout Japan is examined herein. Our simulation shows electricity usage drops 20% during the summer with DS. During the winter, DS helps raise the room temperature by almost 5 C. During the intermediate seasons, the heat in the buffer zone (30W/m 2) is released outside. Through our theoretical and experimental simulations, we verified that DS helps reduce electricity needed to heat and cool buildings in Tokyo, heat buildings in winter in Sapporo, and cool buildings in summer in Naha.
