The present study aims to determine the optimized shape for the maximum electric energy production of building integrated photovoltaic system (BIPV) noise barrier through numerical analysis. The shape of BIPV noise barrier is one of the important factors in determining angle difference between direction vector of the sun and normal vector of the sound barrier surface. This study simulated numerically the flow and thermal fields for different angles in the range from $90^{\circ}$ to $180^{\circ}$, and from the results, the amount of isolation onto noise barrier surface was estimated along the angle between ground and top side of noise barrier. The commercial CFD code (Fluent V. 13.0) was used for calculation. It was found that the maximum amount of insolation per unit area was 19.6 MJ for $105^{\circ}$ case during a day in summer and was estimated 12.4 MJ in $150^{\circ}$ case during a day in winter. The results of the summer and winter cases showed the different tendency and this result would be useful in determining the appropriate shape of noise barrier which can be mounted under various circumstances.

The increasingly high prices for oil, the exhaustion of fossil fuels as well as concern about global warming are driving rapid growth of alternative sources of energy in the world. The active solution for global environment and exhaustion of energy sources is to develop and popularize the technologies to use natural energy such as sunlight, wind, and water. PV(Photovoltaic) modules are efficient devices that has been considered a logical material for use in buildings. Recent advanced BIPV(Building Integrated PV) technology have rapidly made PVs suitable for direct integration into construction in the world. Recently, building has been higher and higher. Tall buildings have many advantages for BIPV such as wide facade area and no shading effect by the surrounding buildings. However. BIPV has not been applied for tall building facade yet. Therefore, the purpose of the research is to develop suitable BIPV for tall buildings and to put these technologies to practical use. Therefore, the purpose of the study is to investigate unification of BIPV to curtain wall to apply BIPV on tall building through research into advanced application of overseas BIPV cases.

국내 제로에너지건축물 의무화를 대응하기 위해서 신재생에너지 자립률을 높이려면 고층 건물일수록 대지면적에 한계가 있고 옥상에 PV모듈을 설치하는 것만으로는 부족하다. 따라서 제로에너지건축물을 실현할 수 있는 핵심 에너지원으로 BIPV(Building Integrated PhotoVoltaic, 이하 BIPV)는 가장 주목받는 산업이다. 이에 본 연구는 BIPV 산업의 올바른 방향 제시와 활성화룰 위해 설계자, 시공자, 제품 제조자, 유지관리자 등 경력 10년 이상 전문가를 대상으로 BIPV 산업의 문제점을 자율 토론 방식으로 설문 조사를 시행하였다. BIPV 적용의 산업적 문제점으로는 제품 인증을 위한 표준 및 인증기준의 범위 확대, 다품종 소량 생산의 현황을 고려한 인증범위 개선, 컬러 모듈과 루버 모듈 및 지붕형 제품을 수용할 수 있는 표준 개정 필요성, 인증제품 의무화를 통한 외산 모듈의 국내 유입 차단의 필요성, BIPV 제품 정보 획득의 어려움, BIPV의 건축 적용 부위 등에 대한 정확한 가이드라인으로 참여자간의 혼란 야기 방지 필요, BIPV 정의의 명확한 정립과 지원 정책이나 제도가 부족하다는 문제들을 도출하였다. 이에 본 연구는 산업계에서 바라보는 시장 변화와 영향을 주고 있는 요소, 경쟁력 강화를 위한 필요한 개선 사항을 바탕으로 대응 방안과 방향성을 제시하고 제안하는데 그 목적이 있다.

Korea has been at the forefront of green growth initiatives. In 2008, the government declared the new vision toward 'low-carbon society and green growth'. The government subsidies and Feed-in Tariff (FIT) increased domestic usage of solar power by supplying photovoltaic housing and photovoltaic generation systems. Since 2000, solar power industry has been the world's fastest growing source with the annual growth rate of 52.5%. Especially, BIPV(Building Integrated Photovoltaic) systems are capturing a growing portion of the renewable energy market due to several reasons. BIPV consists of photovoltaic cells and modules integrated into the building envelope such as a roof or facades. By avoiding the cost of conventional materials, the incremental cost of photovoltaics is reduced and its life-cycle cost is improved. When it comes to atypical building, numerous problems occur because PV modules are flat, stationary, and have its orientation determined by building surface. However, previous studies mainly focused on improving installations of solar PV technologies on ground and rooftop photovoltaic array and developing prediction model to estimate the amount of produced electricity. Consequently, this paper discusses the problem during a planning and design stage of BIPV systems and suggests the method to select optimal design of the systems by applying the national strategy and economic policies. Furthermore, the paper aims to develop BIM tool based on the engineering knowledge from experts in order for non-specialists to design photovoltaic generation systems easily.

BIPV system not only produces electricity at building, but also acts as a material for building envelope. Thus, it can increase the economical efficiency of PV system by saving the cost for building materials. Bifacial solar cell can convert solar energy to electrical energy from both sides of the cell. In addition, it is designed as 3 busbar layout which is the same with ordinary mono-facial solar cells. Therefore, many of the module manufacturers can easily use the bifacial solar cells without changing their manufacturing equipments. Moreover, bifacial PV system has much potential in building application by utilizing glass-to-glass structure of PV module. However, the electrical generation of the bifacial PV module depends on the characteristics of the building surface which faces the module, as well as outdoor environment. Therefore, in order to apply the bifacial PV module to building envelope as BIPV system, its power generation characteristics are carefully evaluated. For this purpose this study focused on the electrical performance of the bifacial BIPV system through the comparative outdoor experiments. As a result, the power generation performance of the bifacial BIPV system was improved by up to 21% compared to that of the monofacial BIPV system. Therefore, it is claimed that the bifacial BIPV system can replace the conventional BIPV system to improve the PV power generation in buildings.

This study was carried out to evaluate the Life Cycle Cost(LCC) of three types of RTPV(Building Integrated Photovoltaic) systems-Glass plus Granite. Crystalline BIPV and See through Amorphous BIPV-which were vertically installed to generate the same power output(76 kW level). Initial investment costs. cost. savings and maintenance costs had been predicted during the period of analysing the LCC of three 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 Class plus Granite when it is backed by more than 20 years of durability.

BIPV system that can alternate building envelope by making materials of PV module should be considered in initial design step for applying PV system efficiently in office building. Mean while, area of the building skin also increases as the number of floors increases, but the valid area that can apply BIPV system in effect decreases relatively. Despite of this weak point, installing BIPV system is still being evaluated as the only measure left that can reduce electronic energy consumption in the building. Therefore, the impact on building energy consumption according to the increase of the number of floors when BIPV system is applied in the building was analyzed. And it will be used as basic information for application of BIPV in office building. Conomic about application of BIPV is interpreted to be secured within the 10 story high. Forover the 11 floors, the methods of increasing the contribution ratio produced by BIPV system through the optimization of install angle and increase in install area of south, high efficiency should be considered. The ways to reduce basic load by integrated design with another renewable energy besides BIPV should be found. Later, the study on the total building energy comsumption with PV generation according to the various type of the basic load and ratio of the width and depth will be performed based on this study.

태양전지를 실제적인 건물의 한 구성요소로 이용하는 건물일체형 태양광발전(BIPV : Building Integrated Photovoltaic) 시스템은 기존의 건물재료를 대체하여 재료비용 및 건설비용의 절감효과를 가져다주며 건물의 미적인 가치를 높여주는 장점을 가지고 있다. BIPV에 대한 연구가 유럽 및 미국, 일본 등의 나라에서 오래전부터 활발히 수행되고 있으며, 시장성 또한 무한 확대되고 있다. 아치형 PV 시스템은 PV 어레이의 직병렬 연결 상태 및 아치각에 따라 효율 특성이 상이하지만 이에 관한 분석은 미흡하며, 아치형 PV 시스템을 설계함에 있어서 미적인 요소만 고려하고 이러한 발전효율에 관한 요소는 전혀 고려되지 않은 채 설계되고 있다. 본 논문에서는 아치형 PV 시스템의 효율에 관한 파라미터인 위도와 경도, 온도 및 일사량, 아치각, 시스템 구성에 따른 각종 손실 등 이에 대한 세부적인 기술검토와 각 장비들의 특성을 정합시켜 아치형 PV 시스템의 최적화를 이루어 효율을 개선시키고자 한다. 아치형 PV 시스템의 효율개선을 위하여 다중제어 인버터 방식을 제안하고 시뮬레이션 툴인 Solar Pro를 이용하여 평판형 및 다양한 아치형 PV 시스템을 구성하여 운전특성을 비교 분석하였다.
