从控制热舒适入手，发掘既有建筑节能潜力--以西安某高校教学建筑为例

当前，国内既有公共建筑的节能改造工作已取得很大成绩，也存在不少问题，亟待总结经验和教训。该文以调查实证为据，针对某大城市既有公共建筑节能改造中出现的一些带有普遍性的问题，重点阐述了合理控制热舒适目标、能耗调查与用能分析对既有建筑节能改造的重要性和现实意义；论文结合西安某高校教学建筑节能改造项目的实践，提出要根据建筑性质和使用特性，对实际的气温和室温做精细化分析，确定合理的热舒适控制目标，并以能耗调查分析为基础，深入挖掘节能潜力，采取综合性节能措施，力争以最少的能源消耗提供舒适的室内热环境。

Identifying Energy Conservation Potentials for Existed Buildings in Terms of Controlling Thermal Comfort:The Case for the Educational Building in Xi'an Colleges and Universities

At present,retrofit of public buildings on energy efficiency in China has achieved gratifying results,yet there are problems to be solved.This paper,based on investigations,examines problems existed during retrofits in metropolis and then demonstrates the importance and significance of controlling thermal comfort standards as well as adopting compositive energy-efficient technologies based on energy diagnosis.The paper takes a retrofit project in an university of Xi’an as an example,points out properties operating characteristic of architecture,advocating that detailed analysis on climate conditions and utilization patterns of target buildings are essential to set reasonable thermal comfort standards;energy diagnosis should also be paid attention to identify the potentials for energy conservation.
