This paper explores the impact of natural ventilation on the indoor thermal environment through an extensive field survey of educational architecture in Cyprus performed both during the winter and summer periods. The study included seasonal indoor and outdoor monitoring of physical parameters, as well as a questionnaire-based survey. The study shows that the naturally ventilated spaces on the upper floor demonstrate operative temperature below the acceptable comfort zone during the winter period, while during the summer period, the findings show the vulnerability of the occupants to summertime temperatures. During the winter, a closed classroom shows the best results in terms of operative temperature; however, this conflicts with the air quality. During the summer, the case of cross-ventilation, both during the day and night, is the most efficient and operative way to passively cool educational premises. Moreover, the results of the subjective survey demonstrate that most students feel comfortable in both the winter and summer demonstrating high thermal tolerance. The results of the current study can be applied to inform strategies for the improvement of thermal comfort and reduction of energy use in educational buildings, as well as the design of new educational buildings.

本文通过在冬季和夏季对塞浦路斯的教育建筑进行了广泛的野外调查，探讨了自然通风对室内热环境的影响。这项研究包括季节性的室内和室外物理参数监测，以及基于问卷的调查。研究表明，上层的自然通风空间在冬季显示出低于可接受的舒适区的工作温度，而在夏季，发现表明乘员容易受到夏季温度的影响。在冬季，封闭的教室在手术温度方面显示出最好的效果。但是，这与空气质量相冲突。在夏季，无论白天还是晚上，都需要换气，是被动冷却教育场所的最有效和最有效的方法。此外，主观调查的结果表明，大多数学生在冬季和夏季都感到舒适，这表明其具有较高的耐热性。当前研究的结果可用于为改善教育建筑的热舒适性和减少能耗以及新教育建筑的设计提供信息。
