Research On BIPV Application Potential In The New Campus Of Tianjin University

Today’s society, because of growing contradiction between huge energy demand andshortage of fossil fuels, the use of renewable energy is imperative. Solar energy is asafe, clean, rapid developing renewable energy which has huge potentiality.Building-integrated photovoltaics technology has many advantages, such as less land,high efficiency, close to the building, low comprehensive cost, which makes it highvalue. Governments around the world have introduced corresponding promotionpolicies to push forward the development of BIPV. Since the21st century, there hasbeen a strong boom of planning university campus in Chinese city and the universitiesare looking forward to building new campuses. Therefore, the percentage of campusbuildings in all social buildings has increased greatly. But compared with the averageenergy consumption of urban residents, campus average energy consumption is higher.Therefore, research of BIPV potentiality in campus environment is not only necessary,but also urgent.In this paper, aiming at campus environment BIPV application, from the perspectiveof architecture design, appropriate design method of campus BIPV is deliberated.Taking Tianjin University’s new campus for example, using Autodesk Ecotectsoftware for simulation, based on Excel, we have an access to annual solar radiationmodel of buildings’envelope in the campus, which helps to distinguish suitableregions for BIPV. On the basis, select appropriate PV modules, use PVSIST softwaredo system annual power generation simulation, calculate the potentiality ofphotovoltaic in the campus. Considering with research of energy consumption in thefull life cycle of different PV modules, two schemes of BIPV system are founded.Then account campus energy consumption so that we can discribe the contribution ofBIPV in the campus. Also environmental benefit from BIPV system is calculatedaccording to the date from IPCC and RETScreen International software.
