Domestic photovoltaic technical development and dissemination is active by world developments of photovoltaic industry. Especially, a study to integrate photovoltaic system in building is actively proceeding. In case of the office building, the opaque wall area shortages because the building mainly consists of the glass curtain wall. In order to apply BIPV(Building integrated photovoltaic) system in the office building, it is effective to apply transparent BIPV window. The office building generates cooling load by the heat of occupants, lighting, equipment and by solar heat gain through glass curtain wall of the office building in the daytime. So, not only solar heat gain but cooling load decrease by low transmittance in case of replacing glass curtain wall as transparent BIPV window and electric energy is additionally produced. It is difficult to secure view and daylighting performance because of low transmittance of PV window. So, clear double window that has high transmittance is applied to the facade while also increasing the area ratio of those from 10% to 70%. This study analyzes cooling and heating energy consumption, photovoltaic power generation depending on decrease of PV window area ratio as clear glass area ratio increase and evaluates total energy consumption. Total energy consumption is sum of cooling, heating and lighting energy consumption. And electric energy produced from photovoltaic regards as consuming lighting energy. Total energy consumption according to the direction is the least In the south side. It's because cooling and heating energy consumption is the least but power generation by PV window is the most. Optimum area ratio of PV window and clear double window according to the direction are concluded. The result finds that building energy consumption is able to reduce to the max in case that area ratio of transparent a-Si PV window and clear double window is 50%:50%. |
