双层幕墙建筑冬季热舒适性现场测试研究

2009年1月14～16日选取一栋双层幕墙建筑的27间办公室进行了热舒适性现场测试实验.客观数据采集和主观问卷调查同时进行.主观问卷调查主要从4个方面展开：个人基本信息、健康状况、当前环境的舒适性和可接受度.共有150人次参加本次主观测试,回收有效问卷131份.根据实验数据整理出预测平均评价、平均热感觉投票、平均热舒适投票、可接受度等指标分布.实验结果表明,引起不舒适的主要原因是较低的相对湿度,由此引起的口干和眼涩成为最主要的不舒适症状,而且女性比男性更加敏感.双层幕墙在隔音方面效果较好,但眩光问题仍然值得重视.

Field measurements on thermal comfort of a building with double-skin faade in winter

Field measurements on thermal comfort were carried out in a building with double-skin faade from January 14th to 16th,2009.Data are obtained by measurements of physical parameters and a questionnaire survey is conducted at the same time in 27 offices of the building.The subjective survey involves questions on demographic information of the occupants,health status,environmental comfort conditions and acceptance.A total of 150 occupants are investigated and 131 questionnaires are completed.The statistical data presents the distributions of predicted mean vote,mean thermal sensation vote,mean thermal comfort vote,thermal acceptability,etc.The results show that low relative humidity is the main reason causing thermal discomfort.The greatest discomfort is dry mouth and eye dryness which are caused by low relative humidity.The females are verified to be more sensitive than the males.Meanwhile,a double-skin faade represents a good noise insulation effect while the glare problem is still unresolved.
