Özet
<p>Today, buildings are operated according to the standards (i.e. thermal), however; the recommended values in the standards might</p><p>not necessarily address occupants’ needs, and, thus, occupant complaints might arise. This study aims at assessing the</p><p>performance of the predicted mean vote (PMV) model to detect occupant thermal dissatisfaction. The case study was conducted in</p><p>a commercial building located in Paris, France between January 2017 and May 2018. Indoor environmental conditions were</p><p>monitored via sensors and an online tool was used to collect occupant thermal complaints. A total of 53 thermal complaints were</p><p>analyzed and the corresponding measurements were checked against the reference values suggested by the ISO 7730 Thermal</p><p>Comfort Standard. The results show that all of the operative temperature measurements both in the heating and cooling seasons</p><p>were within the thresholds suggested by the standards. In addition, the PMV method suggested that only 4% of the occupants</p><p>were dissatisfied with the indoor environment. However; the actual dissatisfaction ratio of occupants was 100% under these</p><p>indoor environmental conditions. The findings of this study show that predefined comfort ranges, and, thus thermal comfort</p><p>standards are not able to predict occupant thermal dissatisfaction.</p>
