GB 50189—2015《公共建筑节能设计标准》典型技术的地区适应性

Regional adaptability of typical energy efficiency technology in GB 50189-2015 Design standard for energy efficiency of public buildings

非透明围护结构的传热系数和窗墙面积比是影响围护结构节能的两个重要方面,机组的性能系数是系统节能的重要参数。以公共建筑模型数据库为研究对象,采用不同类型公共建筑在同一气候区的分布特征加权后的计算结果作为评价该气候区公共建筑整体性能的依据。采用单因素变量分析方法,对相同的节能措施在不同气候区产生的节能效果进行计算研究,从而对节能技术的地区适应性进行评价,单一节能措施节能量的量化分析结果能直接反映该节能措施在该气候区的适用性。

The heat transfer coefficient of opaque structures and the window to wall ratio are the important aspects that influence the energy saving of building envelope. Performance coefficient of water chiller is the key point for energy saving of the system. Taking the public building model database as the research objects, evaluates the overall performance of public building in each climate zone by the final calculating result according to the weighting method of distribution feature. By the single factor analysis method, calculates the energy saving effect of the same energy conservation measures in different climate zones. A quantitative analysis of energy saving measures can directly show the necessity for the application of the energy saving measures.
