| In recent years,with the increasingly prominent problem of energy shortage and environmental deterioration,photovoltaic industry,as the leader of clean energy industry,has shown an unprecedented expansion trend in the global scope.Building energy consumption,as the main part of energy consumption,has accounted for about 30%of the total national energy consumption.In this regard,architects have made constant attempts and explorations to find a balance between photovoltaic energy production and building energy consumption.As a result,building integrated photovoltaics(BIPV)technology emerged as the times require.In April 2018,six departments of the state jointly issued the document "Action Plan for the Development of Intelligent Photovoltaic Industry(2018-2020)",which clearly shows that encouraging demonstration of photovoltaic buildings and urban applications will greatly promote the development of distributed photovoltaic applications.In order to promote the development of renewable energy,new energy technology and related industries in China,the state has formulated the development plan of renewable energy,in which photovoltaic power generation is one of the key areas to support.Photovoltaic building integration has broad prospects for development because of its ecological and sustainable advantages,and has increasingly become a new concept and method of architectural design.However,there are still many problems in the integrated design of photovoltaic buildings.For example,how to improve the overall efficiency of photovoltaic buildings and integrate the photovoltaic design concept into the architectural design has become an urgent problem to be solved.Firstly,the research background of photovoltaic architecture is studied and summarized,and the research object and the next research direction and content are clarified.Then the related theories of photovoltaic building are sorted out and summarized,and the application of photovoltaic system is analyzed,including its development background,material characteristics and photovoltaic building applications.The material properties of photovoltaic materials selected in design practice are experimentally studied.Secondly,the design of specific practical projects is studied.Based on a photovoltaic building integrated full-coverage building design which the author participated in with the tutor,this paper studies the photovoltaic building integrated design in the architectural context from the perspective of architectural design.From the overall layout of the building,the design of photovoltaic facade and the application of photovoltaic technology to elaborate,combing the ideas of photovoltaic architectural design.Through technical analysis and photovoltaic structure design in the early stage of design,the concept and method of integrated design of solar photovoltaic buildings are studied in detail.Through the combination of practice and theory,this paper reveals the relationship between photovoltaic materials and architectural performance art,and explores the architectural detail design,studies the performance and design principles of photovoltaic buildings and environment,and the application of photovoltaic technology in architectural design.In view of the thinking in the design process,a series of key contents to be considered in the design stage of architectural scheme are put forward to achieve the integration of building and photovoltaic system,which further enriches the architectural design theory of photovoltaic building integration.Finally,through all aspects of data feedback after the completion of the project,the relevant design strategies brought about by the photovoltaic demonstration project are analyzed and examined,and the photovoltaic building practice is considered more deeply and widely.The text is an integrated photovoltaic building design aiming at the characteristics of light and climate in Huizhou,Guangdong Province.It can be used as a reference for the design of similar photovoltaic buildings in this area,as well as for the study of integrated photovoltaic building design in other light and climate areas. |
