Occupant behaviour and its relation to climate in Australia

Abstract

Occupant behaviour (OB) is impacted by several interdisciplinary factors: environmental, psychosocial, cultural and economic. One of these impacting factors is the climate. In this study, the patterns of OB interactions with heating, cooling, lighting, equipment, windows and shading collected in questionnaire surveys were used as input data in the simulation models of two university buildings. The buildings, a green-rated and a non-rated one, are in Western Sydney University in Sydney, Australia. Then, the models were simulated in eight different climate zones in Australia. Therefore, this research aimed to understand how different climate zones may impact the energy related to OB and compare this impact between a green-rated building and a building without any rating. The results showed that there is no correlation between climate and OB and the levels of discomfort are related to the cooling season. The green building is less subjected to external changes, indicating that in buildings with automatic and properly controlled centralised management systems, the impacts related to the misuse of energy due to OB would be almost irrelevant. The results of this study should not be extended to other occupant behavioural patterns or situations. The results should be confined within the present research and context.
