| Since the 21 st century,our country are in large-scale planning and construction of the university campus,and colleges and universities respond positively and then they constantly build new campus,making the campus construction greatly improved in all kinds of social construction.According to data of “Annual Development Report of Chinese Construction and Energy in 2010”,the special report released that unit construction area of energy consumption Beijing University Campus Building is up to 52.9k W-H,which is far higher than per capita energy consumption indicators of urban residents.University campus become the key areas of energy consumption.Therefore,in order to reduce the energy consumption and make full use of the new energy,it is necessary to study the application of the integration of photovoltaic building in the campus environment.With regard to the application of photovoltaic building integration in the university environment,in the perspective of architectural design,combined with the engineering example,this paper studies the application of photovoltaic integration in the construction of university.First of all,the development of photovoltaic building integration at home and abroad is expounded;Secondly,it illustrates the concept of building integrated photovoltaic;Thirdly,it enumerates the application of solar photovoltaic power generation in colleges and universities at home and abroad,and then summarizes the principle and its influencing factors of photovoltaic technology,and the strengths and weaknesses of photovoltaic power generation,and also integrated design method and structure of solar photovoltaic.And then taking the Xi’an University Of Architecture And Technology’s Caotang campus as an example,through the investigation and analysis of the environment,it selected the typical architecture for analysis--student canteen.As the basis of Student canteen,it selects the suitable photovoltaic module.For the best angle of photovoltaic module installation,the problem is put forward two kinds of the design method of photovoltaic modules: using the best design of angle and the maximum of effective area.After that,it obtained the capacity of photovoltaic power generation,using PVSIST software for simulated calculating of the power generation month by month.In the end,the results show that the capacity of generating energy in the photovoltaic system using the most large effective area is larger than the design of PV system generating capacity of the best angle of design,h and 315401 k W h and 273354 k W h respectively.At the end,in terms of the application of solar photovoltaic building in Colleges and universities,in aspects of benefits of energy saving,environmental and economic benefits,it concludes as below: in terms of environmental benefits,with the evaluation using IPCC data it calculated annual carbon dioxide emission reduced nearly 107 tons;Secondly,followed by the evaluation of economic benefits,the power output of the whole life cycle can be 6844201.7k W h,saving RMB 3.42 million for electricity costs,RMB 2.87 million for government subsidies,and one-time installed subsidy of 5.5 thousand yuan,and in brief,the total benefit is 5.09 million except for a total investment of RMB 1.747 million.At last,with energy saving,refers to the domestic and foreign research,with recovery period of energy and the index of energy return,with comprehensive evaluation in Colleges and universities solar building integration the recovery period of energy is 3.17 years,index of energy return was 7.89,which is with such good energy-saving.In summary,we can see the application of solar photovoltaic power generation technology in Caotang campus of Xi’an University of architecture and technology,has significant effect on the three kinds of efficiency evaluation.Finally,the paper describes some existing problems,puts forward measures for improvement,to provide a theoretical basis for the future design of solar photovoltaic power generation. |
