As climate change begins to affect every corner of the world, renewable energy becomes increasingly important. However, although the BIPVsystem gets more attention with improved efficiency, its aesthetical design integration is still far behind. Therefore, first, this work analyzesthe aesthetic design aspects of BIPV integrated design through previous studies and IEA studies. Secondly, 12 elements of BIPV systemdesign aesthetic evaluation are derived. Third, these elements are applied to five selected cases to explore the improvement of aestheticdesign elements for BIPV integrated design. In conclusion, the aesthetic elements of BIPV seen through the cases were expressed in anintegrated design as an architectural language based on technology. Among them, color, shape, pattern, composition, and harmony were foundto be important aesthetic considerations of BIPV integrated design. 전 세계적으로 환경문제가 심각해지면서 재생에너지의 중요성이 높아지고 있다. 특히 효율성과 경제성이 향상되면서 BIPV 시스템에 대한 관심도 높아지고 있다. 그러나 BIPV 시스템의 심미적 설계 통합이 여전히 부족하며 이에 대한 연구는 활발히 진행되지 않고 있다. 따라서 본 연구는 첫째, 선행 연구를 통해 BIPV 시스템의 통합 설계를 위한 심미적 설계 요소를 추출하고 분석한다. 둘째, 추출된 12가지 심미적 설계 요소를 기반으로 이를 BIPV 모범 사례에 적용하여 건물일체형태양광(BIPV) 통합설계를 위한 심미적 디자인 요소에 관한 개선 방안을 모색하였다. 결론적으로, 사례들 통해 본 BIPV의 심미적 요소들은 기술을 기반으로 한 건축 언어로 통합 설계로 표현되었다. 그 중 색상, 형태, 패턴, 구성, 조화가 BIPV 통합 설계의 중요한 미적 고려 사항임을 알수 있었다.

The Korean government is actively promoting mandatory zero energy building (ZEB) implementations to achieve its goal of reducing greenhouse gas emissions. Photovoltaic (PV) technologies are hence being applied in the construction of ZEBs, and building-integrated photovoltaic (BIPV) systems are in the spotlight. BIPV systems are presently being integrated in the building envelopes as parts of the buildings, such as facades, roofs, and windows, to produce on-site clean electricity without requiring additional space. However, the monotonous black-colored BIPV modules are not popular because they affect the aesthetics of the buildings. To mitigate this problem, studies have been conducted on colored BIPV modules to improve the aesthetics of buildings by implementing various colored components. Power estimation is an important part of judging the faults in PV systems. Therefore, this paper proposes a performance estimation model using the characteristics of color BIPV systems based on I-V curve measurements. A color BIPV and meteorological monitoring systems were installed to acquire field survey data. The goal of this study was to verify the superiority of the proposed model by comparison with the power estimated using a simulation tool. The proposed model with high-accuracy power estimations is expected to help diagnose the performance of the BIPV system.

Assome of its components are made of combustible materials, it is necessary to evaluate the risk of fire. In this study, therisk of fire before and after BIPV installation was compared through fire simulation using the PyroSim program. Prior tothe simulation, a BIPV combustion characteristic database was established via a cone calorimeter experiment with a BIPVsystem panel, and the results were analyzed through a fire simulation using these experimental values as input values. Thefire risk evaluation confirmed that when BIPV was installed, the fire propagation due to vertical diffusion was fast. Additionally, the amount of heat and smoke emitted increased, resulting in an increase in the risk of fire by 54.94% basedon the center of the building at 805 s. Therefore, it is expected that the results of this study will contribute to securingthe reliability of evacuation and manual measures for people in BIPV-installed buildings as well as improve fire safety.

In this study it was analyzed by the case study the function of the requirement of the BIPV-module as building material and this architectural characteristic according to the 'kind of the module. Therefore the goal of this study is to get securing the application information of BIPV as windowpane. BIPV modules are manufactured in the form of G/G. in the case of the Crystal type the Transparent and the light Transmission is to be adjusted by the spacer attitude of the cell. Although this type could not be optimal for light effect of indoors because of the inequality of shade, the moving shade play makes a dramatic Roomimage by the run of sun. The application of this type would be for canopy, window or roof in the corridor or resounds. With amorphous the type it is to be manufactured simply largely laminar, and thus that will shorten building process. There is a relatively good economy to use and to the window system easily. After the production technology is easy the transparency of the modules to adjust, and the module shows to a high degree constant characteristics of light permeability and transparency. Without mottle of module shade is good the use for the window or roof glazing of office, library, classroom, etc. to adapt. The BIPV modules took generally speaking a function as building material to the daylight use, shading, isolation and also to the sight. That means that BIPV modules have as multifunctional system to sustainable architecture good successes and they are at the same time as Designelement for architecture effectively.

Building-integrated photovoltaic(BIPV) systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Besides of these benefits, the application of PV systems into school buildings tends to play an important role in energy education to students. In this context, this study aims to analyse the applicability of PV systems into school buildings. For an existing school building, four types of BIPV designs were developed; rooftops, wall-attached, wall-mounted with angle, and sunshading device. Based on energy modeling of those BIPV systems, the whole 60.1kWp rated PV installation is expected to yield about 65.6MWh of electricity, that is about 50% more than the annual electricity consumption of the school, 44MWh. It was also found that the applicability of the PV systems into the school building was very high, and the rooftop systems with the optimized angle was the most efficient in energy production, followed by sunshading, wall-mounted with angle and wall-attached. It concludes that school buildings have a reasonable potential to apply PV systems in the aspects of building elements and electricity production.
