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
