基于eQUEST软件的建筑能耗分析方法研究

以杭州地区办公楼建筑为例,采用能耗分析软件eQUEST进行全年逐时、逐月的建筑冷、热、电负荷预测,通过探讨eQUEST软件模拟计算建筑负荷的特点,分析了eQUEST软件使用方法；并选取该办公楼建筑的典型月电负荷模拟计算结果与实际耗电量进行对比,评价了eQUEST软件模拟计算的可靠性结果表明:eQUEST软件能够快速预测建筑全能耗、其操作步骤的简便、具有友好的输入界面,对建筑全能耗分析具有一定的可靠性,是较为实用的快速能耗分析软件但是,其模拟计算结果与实际值仍存在偏差,这些不足之处需要在使用过程中加以修正,如在建筑能耗模拟中采用动态的建筑参数设置值(包括人员密度、新风量、设备能耗、照明能耗、湿度等).

Study on the analysis method of energy consumption of building with eQUEST software

Taking a given office building of Hangzhou as an example,its energy loads of heating,cooling and other electric power consumptions were assessed by eQUEST software within a time-span of hours,days and months respectively for one year.The application method of eQUEST software was in detail introduced.Meanwhile,the reliability of eQUEST software was evaluated through comparing calculating values of energy consumption obtained from eQEUST with the actual values running in the given building.It was proved that eQUEST could give a rapid,overall,and reliable assessment for energy consumption of building.It has a friendly input screen and easy access.However,it needs to note that the errors between the calculation value and actual values are still not negligible.It is necessary to pay more attention to some disadvantages of this software in simulating the building energy consumption,including setting some parameters of building as dynamic values.
