최근, 경제가 발전하고 건축 분야의 에너지소비가 중국 에너지소비에서 차지하는 비중이 점점 커지고 있다. 건축 에너지소비 절감을 에너지소비 절감의 주요 조치로 삼고, 이에 기반하여 건축의 지속가능성을 우리 생활과 밀접한 관련이 있는 주택 설계에 적용하고자 한다. 중국 한대지역 주택 에너지절약 건설에 존재하는 문제와 난제를 해결하고 한대지역주택 동절기 난방기술을 설계, 연구하여 채택한 난방기술이 한대지역의 지속가능한 주택에 널리 보급되고자 한다. 본문은 다섯 부분으로 나누어져 있는데, 첫 부분은 머리말, 연구의 배경, 내용, 방식, 목적을 소개하고 두 번째는 자연형 태양에너지 난방기술을 소개하며 세 번째는 지속가능한 주택의 현황과 발전배경, 네 번째는 피동식 태양에너지 난방기술을 어떻게 지속가능한 건축에 응용시킬 수 있는지에 대한 법규 탐구, 마지막은 연구를 통해 얻은 결론과 미래에 대한 전망을 내 놓았다.

As the balcony expansion of residential building was legalized, the expansion generation is tend to increased continuously of existing residential building or condominium complex. But balcony is the service area. So, it is worried about defect occurrence of extension construction because thermal insulation effect is insufficient to balcony installed an aluminum sash. Therefore, it is desired the method to minimize the damage of performance improvement of the windows which has an influence directly on the performance defect. See-through a-si is effective to reduce the cooling loads and sunlight, to produce the electricity by installing a-si at the wall and windows of residential building. This paper has predicted producing electricity and have analyzed heating/cooling load based on balcony expansion and building-integrated PV installation in residential building.

In the present study, we developed optimal heat supply algorithm which minimizes the heat loss through the distribution pipe line in group energy apartment. Heating load variation of group energy apartment building in accordance with outdoor air temperature was predicted by the correlation obtained from calorimeter measurements of whole households of apartment building. Supply water temperature and mass flow rate were conjugately controlled to minimize the heat loss rate through distribution pipe line. Group heating apartment located in Hwaseong city, Korea, which has 1,473 households divided in 4 regions, was selected as the object apartment for verifying the present heat supply control algorithm. Compared to the original heat supply system, 10.4% heat loss rate reduction can be accomplished by employing the present control algorithm.
