碩士 === 國立成功大學 === 土木工程學系碩博士班 === 100 === This study integrates three main aspects in designing Ventilated BIPV curtain wall structure such as building structure, heat flow technology and solar photovoltaic system. It allows this research to develop a self-controlled environmental system by taking away the heat produced by solar photovoltaic panels through natural forces. It is allowed by the “Double Skin” method, which induces the ventilation inside the PV panels to achieve the cooling effect by reducing self-heat and radiant heat inside the panels. By lowering the temperature inside the PV panels, the indoor temperature can be reduced as well. This research attempts to understand issues related to the design of integrating photovoltaic system into building structure. Research and development of appropriate Ventilated BIPV wall unit was conducted, followed by testing the heat flow with the purpose of obtaining the thermal performance of Ventilated BIPV wall. Energy performance of the Ventilated BIPV wall will be analyzed using energy modeling software, eQuest. Energy saving comparison of the eQuest results will be investigated between two buildings, with and without ventilated BIPV wall installed. As a final point, to verify the feasibility of the proposed Ventilated BIPV curtain wall in building construction, greater effort was directed to implement the physical solid model and creating the life cycle assessment of CO2 emissions. Through those stages, it is expected that this research can grasp the future of such building residential concept which utilizes Ventilated BIPV curtain wall as one of the factors that influence the building energy performance. The results show that Ventilated BIPV curtain wall can improve the energy efficiency of the building. Another improvement of wall insulation performance may also reduce the air conditioning electricity consumption and CO2 emissions as well. These paybacks ease the urban heat island effect and attain the CO2 reduction target of greenhouse gases.
