摘　　要：在企业能源审计过程中,将统计学中的cumulative sum(CUSUM)方法,用于计算企业的节能技改措施节能量并监测技改措施的实施效果,提出了该方法的具体应用步骤,分析了该方法在计算节能量时较基准单耗对比法更为真实的原因。以某建筑陶瓷企业为实际对象,运用该方法所得的结果与实际情况较为一致,从而验证了该方法在企业能源审计中的可行性,建议在企业能源审计中推广该方法。This paper adopts a statistical method named cumulative sum （CUSUM） in enterprise energy audit for calculating the energy saving quantity and monitoring the effect of technical improvement measures, puts forward its concrete application steps, and analyses the cause why this method is more close to reality than the reference specific consumption contrast method. The paper presents the application case study of a technical improvement in a building tile company, obtains accurate energy saving quantity and effect of technical improvement measures so that verifies the feasibility of the CUSUM method in energy audit, and suggests to popularize this method in the energy audit.
