Research On The Analysis Of Energy Consumption At The Beginning Of The Architectural Design Based On The BIM Technology

With the development of our economy and the improvement of people’s livingstandards, the proportion of the building energy consumption become more and morehigh in total energy consumption. According to statistics,50%or more of the substanceand raw materials obtainedfrom the natural world human used to build all kinds ofbuilding and affiliated facilities，thereof the buildings under construction and useconsumes about50%of the global energy; On the other hand, as a developing country,in the process of rapid economic development in our country, it is must to deal with therelationship between the energy and the environment, adhere to the scientificdevelopment concept of people-oriented, comprehensive, coordinated and sustainabledevelopment，realize the intensive use of resources.Energy-saving design of buildings, it is need to grasp the climate, including wind,rain, light, topography, landform and all the local characteristics, but the complexity oftoday’s architecture has greatly exceeded only by the architect subjective judgment orexperience can grasp, this requires advanced computer technology to carry out thecomplex computation and real-time dynamic simulation to analyze energy consumptionof buildings preliminary and to realizegreen energy-saving design of buildings.The integration of a large number of building information technology BIM realizedthis point perfectly and provides a good assistant design tool for designers."Softwareplatform, data format, plus professional analysis software"constitute the basic model ofthe comprehensive application of BIM technology in building energy and environmentalanalysis. We can create a building information modeling simplely through the BIMapplication software, architects can analyze the buildings energy performance of thedesign conveniently at any time and the results obtained can help architects to makereasonable adjustments to achieve better solutions of energy saving. This paper is basedon a different point of design thinking, with an different perspectives of the designprocess do a research on the building energy saving design.Based on the analysis of energy consumption of BIM technology in the applicationof a preliminary study of early energy-saving building design as the research direction,Starting from the planning and design of buildings, based on the theory of theinitial analysis of architectural design of energy consumption of the research,combined with the site of climate, terrain features, the design of the building itself, explore the appropriate, scientific and reasonable design method of BIM technology inbuilding energy efficiency design. First of all, the thesis introduces the development ofBIM technology and its application in the simulation of building energy consumption,secondly analyzes the traditional process and the existing problems of building energyconsumption analysis, and summary up the advantages of energy consumption of BIManalysis technology in the early stages of architectural design of the application researchcombined with BIM building energy consumption analysis,and through thestudy on theBIM technology at the beginning of the construction scheme of auxiliary energy savingdesign of the strategy research, puts forward the purpose of the analysis of energyconsumption at this stage is to do the comparison of before and after the design, all arebased on the results of the analysis of energy consumption toconstruction the realenergy saving buildings.Finally, to the Chongqing second intermediate people’s court for practicalapplication of real expansion design as an example, it demonstrates the feasibilityanalysis of sustainable design by using BIM energy consumption. Energy-saving designof buildings with BIM technology aided to BIM as technical means, in order to buildingenergy efficiency design as the goal, to show how BIM technology support sustainabledesign in architectural design phase.
