摘要
通过对国内外节能量确定方法的对比研究,开展了各方法在公共建筑节能量核定过程中的可行性探讨。在总结重庆地区公共建筑能耗特点基础上,得出重庆市既有公共建筑节能改造的重点应包括建筑围护结构、设备系统以及运行管理模式等。进一步分析发现,针对不同的改造对象,其能耗计算方法也不相同,建筑节能量无法用单一的指标进行描述,且节能量计算时的调整量难以确定,因此提出了将计算条件设定为改造项目设计工况(或相近工况),以行业标准为依据的核定思路,同时还应体现各项节能技术在节能量核定中的贡献率,探讨了单项节能效果与建筑整体节能量相结合的计算方法。
According to the principles of various methods and energy consumption characteristics in Chongqing,new method of energy saving calculation is proposed for public buildings.It's shown that building envelope,facilities and energy management play the key role in energy saving reconstruction.Considering the difficulty of measuring adjustment quantity,the calculation should be under some certain prerequisites(design conditions),also the prevailing industry standards can be fully utilized.During the energy saving calculation,another key point is how to reflect the contribution rate of the single technologies for energy saving reconstruction.
