Indoor environment in office buildings – Perception of personal control and use of adaptive opportunities at workplaces

Abstract

Personal control has a considerable impact on individual perception of the indoor climate. This paper's objective is to shed more light on the perception of personal control at office workplaces by analysing: 1) the impact of perceived control on perception of indoor climate, 2) the effect of office type and season on level of control perceived, 3) objectively available adaptive opportunities; 4) subjective perception of their availability; 5) occupants' desire for certain adaptive opportunities; 6) how often and which controls were exercised; and 7) reasons for not exercising available adaptive opportunities. New variables were introduced: i) consistency of perception of controls and ii) conformity to expectation of controls, and their correlation with the level of personal control perceived hypothesised. A longitudinal survey was carried out in three office buildings (two mixed‐mode, one free‐running) in the hot‐summer Mediterranean climate of Amman, Jordan during four seasons. Indoor climate perception correlates positively with perceived control. Office type affects level of perceived control but not season. Most frequent stated reason for not exercising available adaptive opportunities was ‘no need to change’. In this study, perceived control is not correlated with consistency of perception of controls but correlated with conformity to expectation of controls.
