Extends from Modelica.Blocks.Icons.DiscreteBlock (Graphical layout of discrete block component icon).
Information
Model predicting the state of the West-oriented window with the outdoor air temperature and occupancy.
Dynamics
When the space is unoccupied, the window is always closed. When the space is occupied, the lower the outdoor temperature is, the lower the chance to open the window.
References
The model is documented in the paper "Zhang, Y. and Barrett, P., 2012. Factors influencing the occupants’ window opening behaviour in a naturally ventilated office building. Building and Environment, 50, pp.125-134."
The model parameters are regressed from the field study in a naturally ventilated office building in Sheffield, UK in 2005/2006. The outdoor air temperature range during the study is 0 ~ 30 degC.

Refactored implementation of random number calculations, transfering the local state of the random number generator from one call to the next.
