Subjective Assessment of Occupants’ Perception of Indoor Environmental Quality (IEQ) Performance in Hospital Building

Abstract

This study is aim at determining the perceptions of the three occupants’ groups in hospital buildings on their assessment of IEQ performance. This study data was collected through the subjective assessment of patients, staff, and visitors using a questionnaire as an instrument in measuring the respondents’ perception score on indoor environment variables. The questionnaire administration was carried out in a case study specialist hospital and the data collected was analysed using SPSS Version 22. With a response rate of 90.8%, there was a significant variation in respondents’ perception of the four parameters of IEQ, but no statistical variation in their perception of the overall IEQ. There was no statistical difference in the mean score perception of IEQ between patients and visitors, however, a significant difference in mean perception of IEQ occurred between the staff and both patients/visitors. The perception of IEQ in hospital buildings varies across the three occupants’ groups in hospital buildings. In order to provide an environment that would be conducive and acceptable to all the occupants in hospital buildings, a level of invariance in their perception must be established
