Table 8: Relations between perceived control in low and high control groups and perceived overall comfort. reported in another study [48] where opening windows were the most frequent behavior of controlling thermal conditions. The limited effect of the available control on the perceived control was pointed out in previous studies [23; 24], which found no association between available and perceived control. This could be explained by the fact that occupants could identify the available controls, but they were not allowed to use them or did not know how to set them up or the control types could not respond rapidly. The multilevel model, containing both individual and building characteristics (both general and available control types), showcased 88% variance in perceived control between buildings. A Building's location and the distance with adjacent facades from other neighboring buildings seem to be significant. The area and number of floors were also found to affect occupant control perception. The number of occupants inside the building showed strong effect, especially inside the office, as well as the type of office (private or open space with partitions). [PERSON] et al. [49] remarked that the provision of personal control in open-plan work environments is an important means to alleviating adverse perceptions. Noise due to conversations and phone calls negatively affected the controlling perception, which was expected as people cannot control themselves the level of noise. Around one-third of the occupants reported negative perception of lighting control, which is similar to findings by [PERSON] et al. [50]. [PERSON] et al. [18] and [PERSON] [21] also indicated that the perceived degree of controlling parameters (temperature, ventilation, lighting) decreases with the increased number of occupants inside offices. To some extent, it seems that occupants perceive controlling capabilities better when providing them with the feeling of freedom inside the office buildings. Effort-Reward Imbalance (ERI), which is a critical psychological parameter in office environments, significantly affected control perception and the occupants' perceived comfort inside offices [36]. Moreover, occupants who habitually use air fresheners in their home seem to be more sensitive to adjusting their indoor work environment. The psychological aspect of perceived control is reinforced, as observed by [PERSON] et al. [25]. A significant positive but weak correlation was observed between perceived control and perceived comfort. This finding is in compliance with [PERSON] et al. [23], [PERSON] and [PERSON] [19] and [PERSON] et al. [51]. This work includes a deeper analysis of the appreciation of the perceived control. It should be noted that the analysis using the combined control parameters is not widely used in this type of studies.
