一、背景随着我国经济建设高速发展,环境与资源问题日益突出、节能减排势在必行,我国的国家机关建筑和大型公共建筑高能耗问题突出。为实现企事业单位节能减排,提高能效,需要对典型的用能单位进行能耗监测与评估,因此必须详细掌握用能的特点,即对热源、热网、热用户三部分进行全程的能耗统计与分 I. Background With the rapid development of China’s economy and the increasingly prominent environmental and resource problems, energy conservation and emission reduction are imperative. The problems of high energy consumption of state organs and large public buildings in China are prominent. In order to realize energy saving and emission reduction and energy efficiency improvement in enterprises and public institutions, it is necessary to monitor and evaluate the energy consumption of typical energy-using units. Therefore, it is necessary to have a detailed grasp of the characteristics of energy use, that is, Statistics and points
