摘　　要：梳理了目前国内外标准、指南中给出的3种节能量测量与验证方法的特点和适用性,重点分析了如何确定节能量计算时的修正因素。根据空调系统能耗组成并结合不同节能改造措施,将能耗修正因素分为室外气象条件、室内人员行为和室内热环境需求3类。以某实际工程为例,应用相似日比较法计算了节能量,指出单一采用室外日平均气温作为相似日的判定依据可能不够全面;相似日比较法只考虑了某种负荷率下的节能效果,在此基础上提出了考虑多种负荷率的综合节能率的优化计算方法,并给出2种计算方法的适用性,为现阶段节能量核定工作提供参考。Sorts out the characteristics and applicability of the three energy saving measurement and verification methods given in the current standards and guidelines at home and abroad. Emphatically analyses the correlation factors for determining the energy saving amount. According to the energy consumption composition of air conditioning systems, combined with different energy saving retrofitting measures, divides the energy correlation factors into three categories： outdoor weather condition, human behavior and indoor thermal environment demand. Taking an actual project as an example, calculates the energy savings using the similar daily comparison method. Points out that it is not comprehensive to use daily average outdoor air temperature as a single indicator when applying the similar day method. The similar day comparison method only considers the energy saving effect under a certain load rate. Based on this, proposes an improved method that considering various load rates, and presents the applicability of the two calculation methods, providing references for energy saving measurement and verification.
