摘　　要：为有效降低既有建筑能耗,采用调研和能耗数值模拟相结合的方式确定既有居住建筑降碳改造策略。通过调研分析山东省不同年代居住建筑的实际运行能耗,评估其降碳潜力,并提出合理的改造优先级排序。采用仿真模拟方法对不同年代的建筑进行整体改造模拟,兼顾建筑形式、结构和系统策略,评估其节能降碳效果。研究发现,三个不同年代建筑的单位面积建筑综合能耗均高于75%节能建筑限额指标。其中70年代建筑节能降碳潜力最大,采用整体改造策略可以实现节能66.45%、二氧化碳减排70.01%;80年代的建筑整体策略可以实现节能57.48%、二氧化碳减排68.68%;90年代的建筑可以实现节能43.71%、二氧化碳减排66.30%。本研究为寒冷地区不同时期既有建筑节能降碳改造策略提供参考。To effectively reduce energy consumption in existing buildings,a combination of surveys and energy consumption simulations was used to determine carbon reduction renovation strategies for existing residential buildings.By analyzing the actual operational energy consumption of residential buildings from different eras in Shandong Province,their carbon reduction potential was assessed,and reasonable renovation priority rankings were proposed.According to relevant standards,a simulation method was used to conduct overall renovation simulations for buildings from different eras,considering building form,structure,and system strategies to assess their energy-saving and carbon-reduction effects.The study found that the per unit area comprehensive energy consumption of buildings from three different eras all exceeded the 75%energy-saving building limit.Among them,buildings from the 1970s have the greatest energy-saving and carbon reduction potential,with overall renovation strategies achieving 66.45%energy savings and 70.01%CO 2 reduction.For buildings from the 1980s,the overall strategy can achieve 57.48%energy savings and 68.68%CO 2 reduction.Buildings from the 1990s can achieve 43.71%energy savings and 66.30%CO 2 reduction.This study provides a reference for energy-saving and carbon-reduction renovation strategies for existing buildings from different periods in cold regions.
