摘　　要：徽派民居作为皖南地区传统民居,因建造年代久远,构造老化严重,室内热环境差,且建筑能耗高,民居建筑节能改造需求迫切。选取歙县一处传统徽派民居,使用DeST对民居进行能耗模拟,并对围护结构进行节能改造分析,对不同围护结构节能方案下的节能效果进行定量分析,结合方案节能率和经济效益选取最佳方案。改造后,建筑全年累计能耗降低66.4%,寿命期内净现值为13433.97元,冬季室内温度有一定提升。节能改造对提高民居舒适度和节约能耗有实际意义。As traditional dwellings in southern Anhui,Huizhou style dwellings have been built for a long time,which have serious aging structure,poor indoor thermal environment,and high building energy consumption,so there is an urgent need for energy-saving transformation of dwellings.This paper selects a traditional Huizhou style house in Shexian County,uses DeST to simulate the energy consumption,analyzes the energy-saving transformation of the envelope structure,quantitatively analyzes the energy-saving effect in different energy-saving schemes,and selects the best scheme combined with the energy-saving rate and economic benefits.After the renovation,the annual cumulative energy consumption of the building is reduced by 66.4%,with the net present value during the life span 13433.97 yuan.The indoor temperature of winter has been improved to a certain extent.The energy-saving renovation is of practical significance to the improvement of residential comfort and energy saving.
