In EnergyPlus, there are several ways to model operable windows:
The AirflowNetwork:MultiZone:Component:SimpleOpening and AirflowNetwork:MultiZone:Component:DetailedOpening objects can be added to the model in an AirFlowNetwork to represent operable windows. This paper provides a good overview of how the AirFlowNetwork operates.
The ZoneVentilation:WindandStackOpenArea object allows users to define basic parameters like the size and orientation of the opening, as well as the limits on the outdoor conditions (temperature, wind speed) that determine whether the window is open or closed. The flow through the opening is based on the both the wind speed and the stack effect in the zone at each timestep the window is open. This object can be used without setting up an AirFlowNetwork in the model.
