【摘要】：针对当前既有民用建筑节能改造节能量计算与核定方法尚不完善的现状,通过剖析影响能耗的因素和节能量计算的基本原理,发现利用能耗账单和天气参数等独立变量的函数关系构建回归模型即可方便地计算节能量.经实证研究得知,民用建筑能耗受室外干湿球温度、日照时间等独立变量影响大,受入住率等独立变量影响较小,由此提出了"追踪变量"的概念,用以探索能耗变动的原因及路径,对于制定节能改造方案及推广分户计量等都具有现实的指导意义;节能计量的周期越长节能量累计误差越小,很适于合同能源管理这种按年计量的节能改造模式.
[Abstract]:In view of the present situation that the energy saving calculation and approval method of existing civil buildings are not perfect, the factors affecting energy consumption and the basic principle of energy saving calculation are analyzed. It is found that the energy saving can be easily calculated by using the functional relations of independent variables such as energy consumption bill and weather parameters. The empirical study shows that the energy consumption of civil buildings is greatly affected by independent variables such as outdoor dry and wet bulb temperature, sunshine time and so on. The concept of "tracking variable" is put forward to explore the cause and path of energy consumption change, which is of practical significance for the establishment of energy-saving transformation scheme and the popularization of household metering etc, because it is less affected by independent variables such as occupancy rate and other independent variables, so the concept of "tracking variable" is put forward to explore the cause and path of energy consumption change. The longer the cycle of energy saving measurement, the smaller the accumulative error of energy saving, which is suitable for the annual energy saving transformation mode of contract energy management.
