既有建筑综合节能改造的节能量测量与验证方法探讨

Measurement and Verification Method of Integrated Energy Savings Retrofitting of Existing Buildings

随着建筑节能改造工作的逐步推进,建筑从原来的单项改造趋向于多项综合改造,如何根据具体节能改造内容选用合理、准确、可靠且兼具经济性的节能量测量与验证方法,影响着改造项目投资方的改造积极性、合同能源管理公司的节能收益与投资回收期、项目实施过程的可持续性。针对既有建筑常采用的综合节能改造措施对其节能量测量验证方法进行了探讨,并列举了某杭州四星级酒店综合节能改造措施的测量验证方法以及节约量计算,采用的能耗模型年偏差率在0.5%以内,可应用于该酒店综合节能改造的测量验证。以期为综合建筑节能改造项目的节能量测量与验证方法提供参考。

With the gradual progress of building energy-saving transformation, it is a trend that single transformation change into multiple comprehensive transformation, how to select reasonable, accurate, reliable and economic energy-saving measurement and verification methods according to the specific transformation measures is particularly important, it affects the transformation enthusiasm of the investors, the energy-saving income and investment payback period of the contract energy management company, and the sustainability of the project implementation process. The energy-saving measurement and verification methods are expounded based on the commonly used comprehensive energy-saving transformation measures, supplying an example of the measurement verification method and the calculation process of a four-star hotel in Hangzhou. The precision of hotel annual energy consumption model is controlled within 0.5%. It is expected to provide reference for the comprehensive energy-saving retrofitting project of existing buildings.
