### Combined Perceived Control Versus Building Characteristics
The existence of any kind of operable windows (OR 3.64 up to 6.53) and private and semi-private offices had the highest impact on the perceived overall control (OR 1.58 up to 3.73). On the other hand, the building's location (OR 0.24, 95% CI: 0.06-0.96) and the buildings' number of adjacent facades (OR 0.65, 95% CI: 0.44-0.97) with other buildings tended to negatively associate with the perceived control. Both high number of occupants in the building (OR 0.67, 95% CI: 0.46-0.99) and the type of office (OR from 0.23 to 0.36) had a significant negative effect on the perceived overall control. Indoor noise from distracting conversations was associated negatively with the perceived overall control (OR 0.69, 95% CI: 0.49-0.97). Concerning individual characteristics, in addition to gender (OR 1.21, 95% CI: 1.06-1.38) and age group (OR 0.78, 95% CI: 0.61-0.99), strong association with the overall perceived control was found for the ERI (OR 0.67, 95% CI: 0.46-0.99) and the occupants' habit to use air fresheners at home (OR 1.26, 95% CI: 1.11-1.44). \begin{table}

Adjusted for gender, age groups, effort reward ratio, experience of negative events, use of air fresheners at home, type of job, type of job’s contract, job’s contract duration. Characteristics with a p value lower than 0.20 are presented. Level 1—Occupant level, Level 2—Building level, Level 3—Country level. OR: Odd Ratio, CI: Confidence interval 95%, n1/N1: Occupants’ answers/total number of occupants, n2/N2: building observations/total number of buildings.
