摘　　要：20世纪末的既有公共建筑相对于参照建筑的节能率普遍较低,远未达到现行节能标准,使用时达到一定的舒适度需要消耗较多能源。为了推进云南省温和地区城市更新中的既有建筑节能改造标准编制,进一步完善既有公共建筑节能降碳改造指南,通过对典型案例云南建筑技术发展中心办公楼进行了超低能耗改造设计研究,以模拟计算数据和实际检测数据为依据,系统地剖析了温和地区既有公共建筑超低能耗改造的性能化设计方法和独特构造设计措施。结果表明:云南温和地区的节能改造措施有别于其他气候区,改造成本相对较低;通过对外围护结构进行得当的节能改造和增强气密性,能耗指标将大幅度降低且舒适度提高,可以达到超低能耗建筑节能标准。At the end of the last century,the energy efficiency of existing public buildings was generally lower compared to reference buildings,far from meeting current energy-saving standards.A considerable amount of energy is consumed to achieve a certain level of comfort during usage.The ultralow energy consumption retrofitting design of the office building of Yunnan Architectural Technology Development Center as a typical case is analyzed in order to promote the formulation of energy-saving retrofit standards for existing buildings in urban renewal in mild regions of Yunnan Province,and further improve the guidelines for energy-saving and carbon reduction retrofit of existing public buildings.Based on simulated calculation data and actual detection data,the study systematically analyzed the performancebased design methods and unique structural design measures for ultra-low energy consumption retrofit of existing public buildings in mild regions.The results show that the energy-saving retrofitting measures in Yunnan are different from those in other climate zones,and the retrofit cost is relatively low.By properly retrofitting the building envelope structure to enhance airtightness,the energy consumption index will be greatly reduced,the comfort will be improved,and the ultra-low energy consumption building energysaving standards can be achieved.
