基于主观和客观的数据，进行了研究，以确定在自然通风和空调建筑的办公室工作人员的热舒适感的差异。对访谈的分析表明，自然通风办公楼的居住者对热环境的满意度明显高于空调建筑物的居住者。几个感知参数会影响热舒适度：照明、气流、温度变化、声学、嗅觉质量、眩光和感知控制以及被视为陈旧和干燥的空气。这些参数的影响取决于通风的类型和室内温度的感知（热或冷）。通过Mayer对PMV模型的修正，实现了空调办公室热舒适性预测与主观感受之间的最接近一致。对于自然通风的办公室，ASHRAE方法显示了最佳匹配。
Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-conditioned buildings. Several perceived parameters influence thermal comfort: lighting, draughts, temperature variations, acoustics, olfactory quality, glare and perceived control as well as for air which is perceived as stale and dry. The impact of these parameters depends on the type of ventilation and the perception of the indoor temperature (hot or cool). The closest agreement between predictions and subjective perception of thermal comfort for air-conditioned offices is achieved by Mayer’s modification of the PMV-Model. For naturally ventilated offices the ASHRAE approach shows the best match.
