摘要
根据《节能量测量和验证技术通则》(GB/T28750-2012)中提出的"基期能耗-影响因素"模型法,由居住建筑供暖系统能耗的关键影响因素,通过回归分析建立了居住建筑供暖系统的"基期能耗-影响因素"数学模型,给出节能量的计算和验证方法,以及数学回归模型的显著性检验方法、计算精度要求等,量化了不确定度分析方法。通过某居住建筑节能改造工程实例验证了该方法的可行性及可操作性,为居住建筑供暖系统节能改造工作的开展及推进提供技术支持。
The ＂baseline energy consumption- influencing factors＂proposed by＂General Technical Rules for Measurement and Verification of Energy Savings＂（GB/T28750-2012） were deeply researched.The mathematical model of ＂baseline energy consumption- influencing factors＂for residential buildings＇ heating system was established according to its key influencing factors. A complete description of inspecting mathematical model was also provided, including the significance test and calculation precision test.The methods of measurement and verification and uncertainty analysis on energy savings for residential buildings＇ heating system were proposed. The proposed model was proved to be feasible and operable by an example. Therefore, it is capable to be used in measurement and verification of energy efficiency for retrofitting heating system in residential buildings.
