Information
Model predicting the state of the small window with the outdoor air temperature and occupancy. The definition of large windows was not clearly presented in the original paper.
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 "Herkel, S., Knapp, U. and Pfafferott, J., 2008. Towards a model of user behaviour regarding the manual control of windows in office buildings. Building and environment, 43(4), pp.588-600."
The model parameters are regressed from the field study in 21 individual offices within the Fraunhofer Institute’s building in Freiburg, Germany, from July 2002 to July 2003. The outdoor air temperature during the study is majorly in the range of -5 ~ 30 degC.
