摘要：能源可以通过减少浪费和损失，提高效率，通过技术升级和改进操作和维护来保持。提高能源效率在城市建设方面发挥着重要作用，但在我国，仅有很小一部分的建筑使用了节能手段。其主要原因也在于我国开始重视能源的使用效率的时间较欧美等发达国家较晚，在节能软件、节能设计以及节能设备领域研究尚未成熟。对建筑节能的相关研究主要还是需要依靠使用能耗模拟软件。

对建筑能耗进行预测和优化设计建筑的能耗是模拟软件主要的两个功能。对于一个建筑物来说，建筑造型及其围护结构形式直接影响到建筑物与室外环境的热量传递、自然通风和自然采光，而且不同的建筑设计形式及设备选型产生的能耗大相径庭。

本文主要结合天津某社区文体中心，阐述了相关建筑能耗软件在工程实际使用的应用情况。通过建筑初始的一些相关参数，如所在地点的气象参数，建筑围护结构以及影响室内冷凝、热负荷的设定，逐步建立模型。通过控制变量（这里选定空调机组）的分析方法，利用DeST能耗仿真分析软件，在针对不同冷热源系统的情况下做出建筑的能耗对比分析报告，最后提出最节能的冷热源方案，为之后模拟其他同类型的建筑提供有效的理论参考。同时也研究了相关末端系统对建筑能耗的影响及模拟建筑在实际使用中使用哪种运行模式可以更加节能。关键字：能耗分析，节能研究，节能，DeST

The Research of Energy consumption analysis and energy conservation of the community sports center in Tianjin 

ABSTRACT

Energy can be maintained by reducing waste and loss， increasing efficiency，  and through technical upgrades and improved operations and maintenance. Improving energy efficiency plays an important role in urban construction，but in our country，only a small part is energy-saving buildings. The main reason is that China began to pay less attention to the efficiency of energy use than other developed countries，in energy-saving    software，energy-saving design and energy-saving equipment field research has not yet matured.The related research of building energy-saving mainly depends on the application of simulation software of energy consumption. The main function of building energy simulation software is to predict and design the building energy consumption.

For a building，the form of building and its enclosure structure directly affects the heat transfer，natural ventilation and natural day-lighting of the building and outdoor environment，and the energy consumption of different architectural design forms and equipment selection is quite pergent. This article mainly unifies the Tianjin    Community Sports Center，elaborated the related building energy consumption software in the project actual use application situation. The model is gradually established through some relative parameters of the building，such as the meteorological parameters of the location，the building envelope and the setting of the indoor condensation and heat load. By means of the analysis  of  control  variables，using  DeST  energy  consumption  simulation  software to

analyze the energy consumption of different cold and heat source systems，the paper puts forward the most energy-saving heat and cold source scheme，which provides an  effective theoretical reference for simulating other same types of buildings.At the same time，it also studies the influence of the related terminal system on the building energy consumption and the simulation of the construction in the actual use of which operating mode can be more energy-saving.
