To participate or not to participate? Selecting the Right Participant Profile for Thermal and Visual Comfort Studies

Calis, Gulben; Kuru, Merve; Mouawad, Jessica

Energy consumption reduction in buildings poses great challenges to modern societies in which maintaining thermal and visual comfort is occupants’ primary desire in indoor environments. In order to determine satisfaction levels of occupants, surveys are widely used to obtain feedback with respect to thermal and visual perceptions. However, low participation to the surveys might cause misleading results, and, thus, result in defining wrong strategies to maintain occupant comfort in buildings. Therefore, factors that affect participation to the surveys have to be analyzed so that the surveys can be distributed to the most responsive profile. This study aims at investigating the relationship between factors related to participant profile (gender, age group, energy awareness level and the number of energy activities attended) and survey participation ratio. A survey was conducted in an office building in France between December 19, 2016 and September 25, 2017. A total of 93 occupants participated in the study. The relationship between participation ratio and the occupant related factors were analyzed via Kruskal-Wallis tests. The results show that the energy awareness level has a statistically significant effect on the survey participation ratio whereas gender and age group have not a significant effect on the survey participation ratio. Therefore, this result is a proof that the energy awareness levels of occupants have to be increased in order to reach higher participation ratios.
