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.

This study fouces on the electricity generation of B1PV system in the super-tall buildings. To improve the efficiency of the B1PV system, solar irradiance and air temperature should be taken into consideration. This study does research on, one of two main parameters, the solar irracliance in the super high-rise buildings. According to the measurement of solar irracliance, it increased with altitude. It is, particularly, more obviously in the super-tall buildings than others. Subsequently, to make an accurate B1PV elecrticity generation prediction，it is necessary to anaiyze the solar irracliance distribution on the super-taII building's facade which is a prerequisite for optimal B1PV system design.

This study was carried out to evaluate the Life Cycle Cost(LCC) of four types of BIPV(Building Integrated Photovoltaic) systems -Glass plus Granite, Crystalline BIPV, Crystalline BIPV + Glass plus Granite and See through Amorphous BIPV -which were vertically installed to generate the same capacity(2kW) and the same area. Initial investment costs, cost savings and maintenance costs had been predicted during the period of analysing the LCC of four types of BIPV(Building Integrated Photovoltaic) systems installed for the purpose of evaluating the LCC. In case of cost savings, it had been analyzed by measuring the amount of electric power generated, reduction in lighting load and heat & cooling loads through simulation. From this analysis, it was predicted that the See-through amorphous BIPV offering cost saving advantages demonstrated the economical efficiency similar to the Glass plus Granite when it is backed by more than 20 years of durability.

현대디자인은 대량생산과 대량소비를 통해 소비적인 삶의 방식을 촉진하고 영리창출을 위한 경제적 도구로 간주되어왔다. 그러나 화석에너지를 활용한 생산방식으로 인한 이산화탄소의 배출로 환경오염 문제가 심화되면서 융합연구를 통한 지속발전 가능한 디자인에 대한 관심이 높아지고 있다. 본 연구에서는 지구오염의 주범인 이산화탄소의 약 40%가 발생하는 건물을 지속발전 가능한 디자인의 대상으로 정하였다. 또한 한국적인 친환경건물의 롤모델을 제시하고자 건물일체형 풍력과 태양광 하이브리드 에너지시스템을 갖추고, 닫힌 공간과 열린 공간이 공존하며 수평확장과 수직상승이라는 건물의 구조적인 특성과 유사한 ‘ㅍ(피읖)’과 'ㅂ(비읍)', 'ㅅ(시옷)', ‘ㅁ(미음)’, ‘이응(ㅇ)’ 등의 한글자소를 적용한 건물 디자인을 제안하였다. 그리고 동시대 기술로 건축이 가능하고 아름다운 친환경건물 디자인을 위해서 디자인팀, 기계공학팀 그리고 건축공학팀의 융합연구로 진행하였다.
