Satisfaction is a very important factor in improving productivity and performance in the work environment. This study aims to investigate the levels of occupants’ satisfaction with the indoor environmental quality (IEQ) in the governmental buildings in the Kingdom of Bahrain and to investigate the impact of occupants’ demographics and building attributes (non-IEQ factors) on these levels. For these purposes, the study used a questionnaire that has 17 indoor environmental quality (IEQ) factors in addition to a group of non-IEQ factors. The questionnaire was distributed by hand or using email to 279 employees in the Bahraini governmental sector. The findings of the study revealed that occupants in the Bahraini governmental buildings are not strongly satisfied with IEQ factors, especially with sound privacy, followed by visual privacy and amount of space, and then noise levels. The findings also showed that for most IEQ factors, men are more satisfied than women are, those who work in enclosed private offices are more satisfied than those who work in open-plan offices, and those who have central air-conditioning at their workplace are more than those who have a wall-mounted air conditioner. The impact of age, nature of work, duration of working in the current building and at the current workstation, weekly working hours, and proximity to the window were also investigated. Accordingly, a group of recommendations was suggested aiming to improve the levels of occupants’ satisfaction.

Abstract Indoor environmental quality (IEQ) is a broad concept, which seeks to define when a built space provides welfare to its occupants. In general, it is defined as the condition of thermal, visual, acoustic and air quality comfort and depends on multiple factors. In the case of school buildings, the relevance of IEQ is related to its effects on the wellbeing, health and performance of the students and teachers. This research summarizes previous studies of IEQ from a multivariable perspective to prove that this research area needs to be further developed. Previous results show that an integrated analysis of IEQ parameters could better understand the IEQ perception of their occupants. Research on IEQ in schools generally refers to one or two aspects of the four. Even the most recent research deals with these topics separately, without using a systemic approach. The reductionism generated by isolating parameters allows us to study a parameter in detail but does not evaluate the environmental quality of the space. This is why new metrics are necessary to describe, assess and compare IEQ in educational spaces under a systemic approach.
