既存建築物の断熱強化改修よる低炭素化に関する研究　断熱強化が与えるピーク及び年間冷暖房負荷への影響

抄録

The purpose of this study is to clarify the impact of insulation renovation on air conditioning loads. The amount of reduction in peak / annual heating and cooling load was evaluated for each case of the existing building's envelope opening ratio and insulation renovation area. It has been shown that strengthening insulation reduces the annual heating load and peak heating load, but excessive insulation tends to increase the annual cooling load and peak cooling load.
