Post-occupancy evaluation of office buildings in a Johannesburg country club estate

Abstract

The purpose of this article is to present the findings of a research project aimed at determining the level of satisfaction of building occupants in terms of Indoor Environmental Quality (IEQ) and the effect of IEQ on both the morale and the productivity of the employees working in the complex. The main findings were derived from the perceptions of the employees working in a Country Club Estate (CCE) in Johannesburg, South Africa. The questions asked addressed how poor air quality, lack of access to daylight, unpleasant acoustic conditions, and control over lighting and thermal comfort caused dissatisfaction with the buildings’ IEQ. The data were collected during August and September 2012. Questionnaires were sent to ten office blocks within the CCE complex. A total number of 126 questionnaires were sent out and 102 replies were received. Observations from the data led to the view that the satisfactory level of IEQ awareness is low among the occupants and that the employees have limited control over issues such as air ventilation, artificial lighting and noise in their offices. Organisational structure needs to be formed that will enlighten occupants about factors that contribute to poor indoor air quality (IAQ). Organisational procedures also point to the fact that the level of IEQ is low. The inconsistent ratings that were recorded suggest that there appears to be a major scope for addressing post-occupancy evaluation (POE)-related matters in the complex.
