本研究探讨了特定IEQ因素的感知表现与居住者对其工作空间的总体满意度之间的关系。我们特别研究了通风系统类型（即空调AC，混合模式MM，自然通风NV）对该关系的影响。统计分析来自加州大学伯克利分校建筑环境中心（CBE）的入住后调查数据库，根据居住者是否对相关的环境质量因素感到满意，来估计个别环境质量因素对居住者总体满意度的相对重要性。基于这些分析，15个IEQ因素被分类为基本因素，奖励因素或比例因素，根据他们与总体满意度的关系，如卡诺的满意度模型所描述的。我们发现，空调、MM和NV建筑的居住者对一些IEQ因素的分类不同，这表明不同通风类型建筑的居住者对室内环境的各个方面有不同的期望，并以不同的方式做出反应。一个明显的差异是在热环境条件：在NV建筑中，良好的热条件与显著提高的总体满意度（即强烈的积极影响）相关，但几乎没有明显的不利影响，即使在热性能被认为很差的情况下。另一方面，在空调建筑中，热条件与居住者对工作空间的负面总体评价更直接相关（即负面影响大于积极影响）。最后，在MM建筑中，热条件对总体满意度既有积极的影响，也有消极的影响。
This study explores the relationship between the perceived performance of specific IEQ factors and occupants' overall satisfaction with their workspace. In particular we examine the influence of ventilation system type (i.e. Air-Conditioned AC, Mixed-Mode MM, Naturally Ventilated NV) on that relationship. Statistical analyses were conducted on the post-occupancy survey database from the University of California at Berkeley's Center for Built Environment (CBE) to estimate the relative importance of individual IEQ factors on occupants' overall satisfaction, depending on whether or not the occupants were satisfied with the IEQ factor in question. Based on these analyses, 15 IEQ factors were classified as Basic Factors, Bonus Factors or Proportional Factors, according to their relationship with overall satisfaction, as described in Kano's satisfaction model. We found that the classification of some IEQ factors differed for the occupants of AC, MM and NV buildings, suggesting that occupants of buildings with different ventilation types have different expectations, and respond in different ways to various aspects of the indoor environment. A noticeable difference was in thermal environmental conditions: in NV buildings, good thermal conditions were associated with significantly enhanced overall satisfaction (i.e. strong positive impact), but there was little discernible adverse impact, even when thermal performance was deemed to be poor. In AC buildings, on the other hand, thermal conditions were more directly associated with negative overall evaluations of workspace by occupants (i.e. greater negative impact than positive impact). Finally, in MM buildings, thermal conditions exerted both positive and negative impacts of comparable intensities on overall satisfaction.
