一、建筑节能的控制指标和单项指标建筑物耗热量系指在采暖期内室内外平均计算温差条件下，建筑物单位面积、单位时间内消耗的热量。建筑物的能耗是由其围护结构的热传导和冷风渗透两方面造成的。为了降低能耗，均从单项如墙、顶、门、窗等围护结构着手。在节能设计标准中，规 First, the building energy-saving control indicators and individual indicators of building heat consumption refers to the average indoor and outdoor temperature calculation within the heating period, the building unit area, unit of time consumed heat. The energy consumption of a building is caused by both the thermal conduction of the envelope structure and the penetration of cold wind. In order to reduce energy consumption, we started with individual envelope structures such as walls, ceilings, doors, and windows. In energy-saving design standards, regulations
