【摘要】：伴随着中国经济的飞速发展和逐渐提高的生活水平，在社会总能耗中，建筑能耗所占的比例越来越高，据统计，人类从自然界所获得的50%以上的物质原料用来建造各类建筑及其附属设施，这些建筑在建造与使用过程中消耗了全球能源的50%左右；同时作为发展中国家，处于经济高速发展和现代化的进程中，必须要协调好能源利用与保护环境的关系，坚持以人为本和可持续发展观，最大化的实现资源集约利用。建筑的节能设计，需要对气候，包括风、光、雨，对地形、地貌等一切地方特质的把握，但是当今建筑的复杂程度已经大大超过了仅凭建筑师主观判断或者经验就可以把握的程度，这就需要凭借先进的计算机技术进行复杂的数据计算和实时的动态模拟,来进行建筑物初步的能耗分析,实现建筑的绿色节能设计。而整合了大量建筑信息的BIM技术很好的实现了这一点，给设计师提供了一个良好的辅助设计工具。“BIM软件平台—数据格式—专业分析软件”构成了BIM技术在建筑能耗和环境领域综合应用的基本模型。通过相应的BIM应用软件，创建简单的建筑信息模型，建筑师随时可以方便地对设计方案进行建筑物能耗性能分析，得到的分析结果可以帮助建筑师对方案作出合理的调整，更好的实现节能。而本文正是以这一不同角度的设计思维、设计过程展开对建筑的节能设计研究。本文基于BIM技术的建筑能耗分析在设计初期的应用为研究方向，从建筑的规划与设计出发，以建筑设计初期的能耗分析为研究理论基础，结合场地气候、地形特征，建筑本身的设计，探讨BIM技术在建筑节能设计中适宜、科学、合理的设计方法。首先，论文介绍了BIM技术的发展及其在建筑能耗模拟中的应用，其次分析了传统建筑能耗分析的流程和存在的问题，并结合BIM建筑能耗分析的方法，总结出BIM能耗分析技术在建筑设计早期阶段的应用研究的优势，并通过BIM技术在建筑方案初期辅助节能设计中的策略研究，提出这个阶段能耗分析的目的在于设计方案前后的比较，均以能耗分析的结果为依据，从真正意义上构建节能建筑。最后，以重庆市第二中级人民法院审判法庭用房扩建设计为实际案例进行实践应用研究，从而论证利用BIM能耗分析技术进行可持续设计的可行性。通过BIM技术辅助建筑的节能设计，旨在以BIM作为技术手段，以建筑节能设计作为目标，展现BIM技术如何在建筑设计阶段支持实现可持续设计。
[Abstract]:With the rapid development of Chinese economy and the gradual improvement of living standards, the proportion of building energy consumption in the total social energy consumption is increasing. According to statistics, More than 50 percent of the material that man gets from nature is used to build buildings and their ancillary facilities, which consume about 50 percent of the world's energy in the process of construction and use; and as developing countries, In the process of rapid economic development and modernization, we must coordinate the relationship between energy utilization and environmental protection, adhere to the people-oriented and sustainable development concept, maximize the realization of intensive use of resources. It includes wind, light, rain, and all the local characteristics of the terrain and landform, but the complexity of today's architecture is much greater than the architect's subjective judgment or experience alone. This requires the use of advanced computer technology for complex data calculation and real-time dynamic simulation to carry out preliminary energy consumption analysis of buildings. To realize the green energy saving design of the building. And the BIM technology, which integrates a lot of building information, has done this very well. "BIM software platform-data format-professional analysis software" constitutes the basic model of BIM technology integrated application in the field of building energy consumption and environment. With the corresponding BIM application software, a simple building information model is created. The architect can easily analyze the building energy consumption performance of the design scheme at any time, and the analysis results can help the architect to make reasonable adjustments to the design scheme. Better energy saving. In this paper, based on the design thinking from different angles, the energy saving design of buildings is studied. The application of building energy consumption analysis based on BIM technology in the initial stage of design is the research direction, starting from the planning and design of buildings. Based on the energy consumption analysis in the early stage of architectural design, combined with site climate, terrain features and the design of architecture itself, this paper discusses the appropriate, scientific and reasonable design method of BIM technology in building energy saving design. Firstly, the paper introduces the development of BIM technology and its application in building energy consumption simulation. Secondly, it analyzes the flow and existing problems of traditional building energy consumption analysis, and combines the method of BIM building energy consumption analysis. This paper summarizes the advantages of BIM energy consumption analysis technology in the early stage of architectural design, and studies the strategy of BIM technology in the early stage of building energy saving design. It is put forward that the purpose of energy consumption analysis in this stage is to compare the energy consumption before and after the design. Based on the results of energy consumption analysis, the energy saving building is constructed in a real sense. Based on the practical case study of the expansion design of the trial court of Chongqing No. 2 Intermediate people's Court, the feasibility of using BIM energy consumption analysis technology to carry out sustainable design is demonstrated. The purpose of this paper is to show how BIM technology can support sustainable design in the stage of architectural design by using BIM technology as the technical means and taking building energy-saving design as the goal.
