摘要:为推进我国建筑业节能的发展，改善大型公共建筑能耗量大的现状，对BIM技术在我国的应用现状进行综述。以某一公共建筑为研究对象，基于BIM技术的应用，运用建筑热环境模拟计算工具DeST软件对其分项能耗进行分析，得出其建筑热工性能、照明系统以及空调系统的节能统计结果，为能耗监测系统的设计提供方向。基于统计结果的分析可知该公共建筑整体能耗量大，需进行实时监测，因此从三方面设计了能耗监测系统的基本功能和系统架构，旨在构建可靠、高效、共享度高的能耗数据库，建立能耗监测、统计、公示平台，对推动BIM技术在建筑节能方向的应用具有一定研究作用和价值。

Abstract: In order to promote the development of energy-saving construction industry in our country and solve the current situation of large amount of energy consumption of public building, the current situation of BIM technology application has been reviewed.Based on the application of BIM technology, to analyze the separate energy consumption of the public buildings by the DeST software which is a kind of building thermal environment simulation tools.Then, statistical results could be produced, those are for the thermal performance, lighting system and air conditioning system, which can point out the direction of designing the energy consumption monitoring system.Based on the analysis of statistical results, it could be concluded that the overall energy consumption of the building is enormous, which needs real-time monitoring.Accordingly, to design the basic functions and system architecture of the energy consumption monitoring system from three aspects.The design is aimed at building a reliable, efficient and sharing energy consumption database for the energy consumption monitoring system.To establish the platform of energy consumption monitoring, the statistics and the publicity could promote the application of BIM technology in the building energy-saving, which has some reference value to research.
