摘　　要：建筑节能是目前全世界各国家共同关注的重要话题,供热系统节能改造是建筑节能的重要组成部分,而科学统一的供热节能量计算方法是目前函待解决的重要问题。本文通过分析影响供热系统能耗的关键因素,选取室外温度累计值,建立了供热系统"基期能耗—影响因素"的数学模型,提出了适合于供热系统节能量的计算和验证方法及不确定度分析方法,并通过北京某供热中心供热节能改造实例验证了方法的可行性,为供热系统节能改造项目的节能量测量和验证提供技术支撑。Energy saving of buildings is an important topic of global concern. Energy saving transformation of heating system is an important part of energysaving of buildings. How to determine a scientific and uniform calculation method of quantity of energy saving during heating is an important problem to be solved. The key factors that influence the energy consumption of heating system were analyzed, the cumulative temperature outdoors was selected, and a mathematical model of ＂energy consumption in base period-influencing factor＂ of heating system was set up. The method suitable for calculating and verifying the quantity of energy saving of heating system and the analytic method of uncertainty were proposed. The energy saving transformation of heating system in a heat supply center of Bei^ing demonstrated the feasibility of the methods. The proposed method provides a technical support for calculating and verifying the quantity of energy saving during the energy saving transformation of heating system.
