Occupant behavior energy simulation method based on cosimulation

In current building energy modeling (BEM) programs, the information of occupants in the room and the on/off state of the equipments are mainly described by the simple fixed schedules. The randomness, complexity and diversity of occupant behavior can not be fully characterized. Develops an occupant behavior functional mockup unit (obFMU) to realize cosimulation with BEM programs based on functional mockup interface (FMI). Illustrates the method of cosimulation using obFMU by an example of air conditioning switch control.
