典型绿色办公建筑能耗差异校验与敏感性分析*
Energy consumption difference verification and sensitivity analysis of typical green office buildings
摘要：
建筑实际运行时常表现出与设计阶段预测值间的巨大能耗差异，非建筑设计工况下的运行也存在着极大的节能空间，在此情况下，借助建筑模拟工具探究能耗差异产生的原因及优化手段的节能潜力是现有研究的常用方法。借助EnergyPlus对4栋不同气候区的办公建筑进行了基于实际测试的建筑模型校准，分析能耗差异产生的原因，并对围护结构传热系数、室内温度、室内设备功率密度、建筑渗漏量这些输入变量进行了局部敏感性分析。研究结果表明，室内温度对建筑能耗具有最强的敏感性。
Abstract：
The actual operation of a building often shows a large energy consumption difference with the predicted values at the design stage, and there is also a huge energy saving potential for operating under non-architectural design conditions. Therefore, using building simulation tools to explore the causes of energy consumption differences and optimize the energy saving potential is a common method. With EnergyPlus, calibrates the building models based on actual tests for four office buildings in different climate zones, and analyses the causes of energy consumption difference. Explores the impact of input variables including heat transfer coefficient of building envelope, indoor temperature, power density and building leakage on energy consumption through local sensitivity analysis. The results show that the indoor temperature is the most sensitive to energy consumption.
