Building simulation Occupant behaviour Energy use

Simulation of building performance is increasingly being used in design practice topredict comfort of occupants in finished buildings. This is an area of great uncertainty:what actions does a person take when too warm or suffering from glare; how is comfortmeasured; how do groups of people interact to control environmental conditions, etc? Anincreasing attention to model these issues is evident in current research.Two issues are covered in this paper: how comfort can be assessed and what actionsoccupants are likely to make to achieve and maintain a comfortable status.
