摘要
以重庆居住建筑典型户型为例,采用EnergyPlus软件对既有居住建筑的供暖、供冷负荷及能耗进行了模拟,分析了使用不同被动技术改造组合时供暖、供冷负荷情况。基于20 kW·h/m^2的供暖、供冷总能耗目标,计算了不同被动技术改造组合下的最低全年性能系数,作为主动性能提升的参考。提出了集成式建筑被动技术改造优化与主动性能提升相结合的低能耗设计策略,可为位于长江流域的重庆地区既有居住建筑节能设计与高效运行提供路径和方法。
Taking a typical urban residential building in Chongqing as an example,analyses the heating and cooling loads and energy consumption of existing residential buildings using EnergyPlus software.Investigates the heating and cooling loads using different passive measure combinations.Aiming at 20 kWh/m^2 of the annual total space heating and cooling energy consumption target,calculates the lowest annual performance factor under different passive technology design combinations as a reference for active system performance improvement.Proposes a low energy consumption retrofit strategy combining passive technology optimization and active performance improvement,which provides a pathway and a method for energy efficient building design and system operation of existing residential buildings in Chongqing of the Yangtze River Basin.
