Although buildings are operated according to the standards, occupant complaints may arise when there is a mismatch between indoor environmental conditions and actual user needs. Therefore, the accuracy of thermal comfort prediction models suggested by the standards and alternative prediction models need to be investigated. This study aims at assessing the performance of the predicted mean vote (PMV) model suggested by the ISO 7730 Standard to detect occupant thermal dissatisfaction. In addition, a multivariate logistic regression model was developed to predict thermal complaints with respect to “too warm” and “too cold.” This case study was conducted in a commercial building located in Paris, France, between January 2017 and May 2018. Indoor environmental conditions were monitored via sensors and an online tool was used to collect occupant thermal complaints. A total of 53 thermal complaints w...

Ancak, yapim isi sozlesme bedelinin ihale usullerinden ve/veya sozlesme turunden etkilenip etkilenmedigi konusunda aciklik yoktur. Bu calisma, (1) sozlesme bedeli ve ihale usulu (2) sozlesme bedeli ve sozlesme turu (3) sozlesme bedeli/yaklasik maliyet orani ve ihale usulu arasindaki iliskinin arastirilmasi amaclamaktadir. Bu kapsamda 2007 ve 2017 yillari arasinda gerceklesen yapim isleri verileri analiz edilmistir. Sonuclar, ihale usulu ve sozlesme turunun sozlesme bedelleri uzerinde istatistiksel olarak anlamli etkisi oldugunu gostermektedir. Ayrica, pazarlik usulu ihale turu, sozlesme bedeli/yaklasik maliyet oraninda istatistiksel olarak farka neden olmaktadir.

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