Photovoltaic(PV) permits the on-site production of electricity without concern for fuel supply or environmental adverse effects. The electrical power is produced without noise and little depletion of resources. So BIPV(Building-Integrated Photovoltaic) system have been increased around the world. Hereby the relative installation costs of the system will be relatively low compared to traditional installations of PV in high-rise buildings. This paper examined possibility of building integrated balcony PV system and analyzed both performance and problems of this system. The system is influenced by conditions such as irradiation, module temperature, shade and architectural component etc. IF this BIPV system of 1.1kW is possible the natural ventilation in the summer case, the temperature of PV module decrease and the the efficiency of PV system increase generally. By the results, the annual averaged PR of BIPV system of cold facade type is about 74.7%.

The types of installation of the photovoltaic system applied to domestic residential buildings are classified as follows: Mounted modules with air circulation, semi-integrated modules with air duct behind, integrated modules with fully insulated back. In order to study generation characteristics of PV system, we verified the validity of interpretation program based on long-term measurement data of demonstration house installed in BAPV form and also analyzed the generation characteristics and performance of each installation type. The results are as follows. First, the RMSE of amount of generation and simulation according to annual daily insolation of demonstration system located in Daejeon was 0.98kWh and the range of relative error of monthly power generation was -5.8 to 3.1. Second, the average annual PR of mounted modules was 82%, semi-integrated modules 76.1% and integrated modules 71.9%. This differences were attributed to temperature loss. Third, the range of operating temperature of annual hourly photovoltaic modules was –6.5 to 61.0°C for mounted modules, –6.0~73.9°C for semi-integrated modules and –5.5 to 88.9°C for integrated modules. The temperature loss of each installation type was –14.0 to 16.1%, –13.8 to 21.9%, and –13.6 to 28.5%, respectively.

The purpose of this research is to analyze the generation efficiencies of Photovoltaics and Building Integrated Photovoltaics systems and their expected effects on quantified installation areas, based on a literature review of studies which include either system. Besides those, it is to scrutinize the design elements of the buildings with BIPV systems and to explore the feasibilities for their applications in domestic building design. The literature review includes the studies of generation efficiencies measured in laboratories and by computer simulations for PV modules, which were opaque or semi-transparent. Findings are the generated electricity of both systems almost equals when a PV system is installed in 30 degrees independently and a BIPV system is installed in 90 degrees on the south side walls of a six-story or over building with 2:1 ratio of a south side wall to east or west side wall in areas, although the electricity of BIPV system itself has about 30 percent less generation efficiency than that of PV system. The BIPV system has benefits in the generated electricity 1.95, 3.9, 5.85 times more on the south side walls of a ten-story, of a twenty-story, and of a thirty-story building respectively. The BIPV system is expected to have better facade insulation, cooling and heating loads, double envelop effects, and less lighting load in the aspect of energy efficiency, and to have less electricity loss and construction cost, no separate site needed for the system.

The purpose of this study is to deduct BIPV system installation current status and characteristics of BIPV module size and output through case analysis of building integrated photovoltaic systems applied in public buildings by new & renewable energy installation obligation system from 2007 to 2012 and present BIPV system supply performance improvement plan. Analysis by year, capacity, subject organization, facility categorization of BIPV system and size, output by unit area of BIPV module was analyzed. The analyzed results are as follows. (1) BIPV system was installed in 71 locations of 2.7MW from 2007 to 2012 and frequency by BIPV system installation capacity range was highest in 10kW∼20kW with 31%. Also, it was most applied in public work facilities with 33.8% and next was education·society educational institutes with 26.8%. (2) BIPV module was most installed in building facades instead of curtain walls in which form was G-to-G double-glaing type and G-to-T type with proportion of 38% each. (3) BIPV module size was all under 2㎡ and most size was 1.0∼1.5㎡. This size is scarce to replace building material with BIPV module. Therefore, research development on large-scale BIPV module is required. (4) BIPV module output by unit area was most frequent in 100∼125W/㎡. Based on these results, it is thought that 9∼10㎡ installation area is required to install 1 kW BIPV system. Also, high-efficiency of BIPV module is required to install BIPV system of more capacity in limited area.

We intend to describe a 12kW building-integrated photovoltaic system which was applied into the south wall of a new building. This study showed the results that were appeared from describing the PV module manufacture and installation process, and performing generation performance analysis of BIPV system. From the result we confirmed that the generation performance of the BIPV system was changed by season. The performance ratio(PR) was about 83.6% in winter and it means that performance of this BIPV system was so good in that season. On the other hand, the PR in summer was about 75.0% dropped about 8%. It was believed that the change was influenced by the reduction of solar radiation irradiated into the PV modules by installation position and rainy spell in summer. And we also confirmed that low irradiation condition is cause of the additional loss in the total PV system. In this case, the efficiency ratio of PCS drops significantly at low input loads and the average conversion effieciency of PCS in summer was 76.4% decreased about 10% from 86% in winter.

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. The contemporary design has been regarded as a tool for economic advance, it promotes consuming life style as well as profit creation via mass production and mass consumption. However, as the environmental contamination gets intensified by carbon dioxide emissions from a fossil energy-based production method, corporations and designers are now showing interest in sustainable design through convergence research. In this study, buildings which are responsible for nearly 40% of greenhouse gas emissions were selected as a subject for sustainable design. In addition, in order to suggest a role model for Korean eco-friendly building, the study worked on a building-integrated wind power and photovoltaic hybrid energy system. A Design motif of the Hangeul consonant, ``pi-eup(ㅍ)`` applied to the building. Its features are the coexistence of an enclosed and open space, and the horizontal and vertical extension which are considered structurally similar to those of the building. Also, other Hangeul consonants like ``bi-eup(ㅂ)``, ``si-ot(ㅅ)``, ``mi-eum(ㅁ)``, ``yi-eung(ㅇ)`` and others are used too. Add to that, for a beautiful green design that could be built with existing technologies, the study conducted convergence research in cooperation with a design team, a mechanical engineering team and an architectural engineering team.
