    为研究夏热冬暖地区居住建筑应对气候变化的适应性,运用TRNSYS动态能耗模拟软件对该地区典型居住建筑能耗进行仿真,制定了居住建筑节能星级评估体系。以广州市为例,分析预测了广州2020年、2050年及2080年的气候变化,并提出应对气候变化的节能措施。研究表明:气温上升1℃,4.0、5.5及6.5星级建筑能耗将分别增长25%、20%及20%;到2080年,气温上升近3.5℃,4.0星级建筑CO2年排放量达53 t/m^2,将4.0星建筑升级到5.5和6.5星级,每年可相应减排19.5 t/m2和23.2 t/m^2;若以4.0星级建筑当前的CO2排放量为控制目标,则需把建筑围护结构热工性能提升到6.5星级水平,可以实现未来70年减排45%

    对夏热冬暖地区某办公建筑进行能耗测试,利用能耗模拟软件TRNSYS对该建筑空调能耗进行模拟,分析空调冷负荷对于各围护结构的敏感性,对影响能耗显著的外墙、遮阳系数及建筑渗透率进行改造。利用NPV动态经济评价体系,在建筑运行时间内对26种改造方案进行节能经济性分析。结果表明,外墙中度强化、建筑渗透率高度强化及遮阳系数高度强化方案的经济收益值最大,改造成本回收年限较短,为经济性最优改造方案
