친환경 주택용 단열기준이 공동주택 단위열부하에 미치는 영향

In order to investigate the effects of the insulation regulation for eco-friendly houses on the unit thermal load for apartment houses, we calculated the unit thermal load of two apartment models, abiding by two kinds of insulation regulations of the Korean government. In case that the insulation regulation of windows, front walls and side walls for eco-friendly houses were strengthened by 40.0%, 23.4% and 22.9%, respectively against present insulation regulation, the unit heating load of a 85 ㎡ household was decreased about 25.8%, while the unit cooling load was decreased about 2.1%. As result, the insulation regulation for eco-friendly houses decreased the unit heating load effectively.
