摘要
为了研究温和地区公共建筑通过被动式手段来实现"近零能耗"获得舒适的室内热环境的可行性,以贵阳市一栋自然通风(Free-running)办公楼为例,通过长期连续的室内环境参数测量与现场问卷调查相结合的形式,把结果与中美两国的热舒适标准包括热适应模型的舒适区进行了对比分析。结果表明:①该建筑室内环境的预测平均热感觉PMV与实际热感觉投票值TSV有显著偏离,并有大量状态点偏离现有标准的舒适区,但大部分室内人员的反应却是没有不舒适或者有点不舒适。②在温和地区的办公建筑采取适合的被动式环境控制措施,完全可以保证建筑在大多数时间满足室内人员的热舒适要求。③在为温和地区设计依赖自然通风等被动式手段的公共建筑,以及对其进行热环境评价的时候,应该充分考虑当地人群对气候的热适应性。
In order to study the feasibility of achieving a comfortable indoor thermal environment with"nearly zero energy"by passive measures for public buildings in mild climate zone,a field study in a free running office building in G uiyang were conducted as an example.By means of long-term and continuous indoor thermal environmental parameter measurement and field questionnaire survey,the results were compared with the comfort zones of thermal comfort standards of China and United States including thermal adaptive model.The results indicated that:①the predicted mean vote(PMV)of indoor environment deviated significantly from the actual thermal sensation votes(TSV).A mass of state points are outside the comfort zone of the existing standards.However,most of the occupants in the building responded with no discomfort or a lightly discomfort.②appropriate passive strategies of environmental control intervention are adopted in office buildings in mild climate zone,which can enable to meet the requirements of indoor thermal comfort of occupants during most of the time.③when designing the free running public buildings that rely on passive measures such as natural ventilation,or conducting thermal environmental assessment in mild climate zone,the thermal adaptation of local residents to the climate should be fully considered.
