Occupants' perceived importance and satisfaction with the indoor environmental quality of a green building

This study examines occupants' satisfaction with the indoor environmental quality (IEQ) of a green-certified building [The Green Star South Africa (SA) Building] in Ghana. Views of 300 respondents are solicited on 15 IEQ (obtained through a critical review of the literature and complemented with a pilot interview on the subject) parameters. Data obtained are analysed using both descriptive and inferential statistics. suggest that occupants are generally satisfied with five critical aspects of IEQ. The results also indicate that the occupants perceive five key IEQ parameters to have high levels of importance. Further inferential analysis of the parameters revealed that two core IEQs require the highest levels of improvement actions. The study was conducted in Ghana and analysed occupants' perceptions of working within one green-certified building. Again, the collection of the occupants' responses was not linked with the direct measurement of physical characteristics of the IEQ parameters of the building. Hence, the findings cannot be generalised. Practically, the study contributes to providing all stakeholders involved in the Green Star SA Ghana certification system with the relevant feedback for their decision-making on current and future projects to be certified under this certification system. This study provides valuable information on the performance of IEQ parameters of the building and points out potential IEQ areas that need improvement efforts, especially concerning current and future facilities certified under this certification system.
