既有建筑节能改造中部分建筑功能改变的节能量计算
Energy saving calculation of existing buildings retrofitting with part function changes
摘要：
节能量认定是采用合同能源管理等市场机制模式开展公共建筑节能改造的核心问题和难点之一，而对于改造后部分建筑功能发生变化的节能改造项目而言，节能量的认定尚无分析方法。基于《国际节能效果测量与验证协议》，提出了针对建筑功能部分变化的综合节能改造项目的节能量计算办法，即首先在基准期能耗基础上进行建筑功能变化的调整，然后在报告期能耗的基础上进行其他独立因素的调整，两者之差即为节能量。对实际改造项目进行案例应用分析，结果表明，案例中调整后的节能率仅为根据项目改造前后能耗账单直接相减得到的节能率的1/2。
Abstract：
The accurate quantification of energy savings is one of the key issues in the energy saving retrofitting of public buildings adopting contract energy management. There is no calculation method available to determine the amount of saved energy for retrofitting projects with part function changes. Puts forward a calculation method for the projects based on International performance measurement and verification protocol. The amount of saved energy is calculated using the differences of adjusted energy consumption between baseline period with building function changes and report period with other independent factor. The method is used in a case. The result shows that the energy saving rate using the method is only half of that calculated based on the difference between energy bills before and after modification.
