    Physical and perceptual gap in indoor environmental quality: a mixed method study of space and users at an aged care facility in Victoria

    Nearly a quarter of a million of Australia's ageing population live in residential aged care facilities. Given the growing ageing population in Australia, it is important to understand the indoor environmental quality (IEQ) of these settings in consideration of not only measurable IEQ data but also senior occupants’ perceived comfort for their health and wellbeing. In this research, a residential aged care facility was selected in Victoria, Australia, as a case study to examine these relationships across different seasons. IEQ monitoring devices were deployed for continuous and instantaneous data collection on site. Questionnaires and personal interviews were also conducted across three user groups (residents, staff and visitors) to establish an understanding of the users’ perceptions. This study found the existence of a gap between measurable and perceptual IEQ according to the building configuration and occupancy as well as the user lifestyle and activity.

    The aged population in Australia is expanding rapidly. To cater for the Australia’s ageing population, there is a significant increase in demand for aged care facilities over the coming decades. The indoor environmental quality (IEQ) affects users’ physical health and psychological wellbeing. However, systematic research on the relationship between users’ perceptions and IEQ of aged care facilities has yet to be developed. In this pilot study, a residential aged care facility in Melbourne was selected as a case study for investigating the differences between the measured IEQ data and the users’ perceived individual comfort. A questionnaire survey was conducted to collect the perceptions of users on IEQ. Environmental sensors which enable web-based data monitoring were deployed. The measured data were then analysed together with the questionnaire survey results for drawing a comparison with the users’ perceptions. It was found that the measurements by environmental sensors are realistic and the survey questionnaires are appropriate for the study. For the future surveys, the language barrier needs to be considered for non-English speakers.
