modelHaldi2008BlindsTOut
A model to predict occupants' blinds behavior with outdoor temperature
Extends from Modelica.Blocks.Icons.DiscreteBlock (Graphical layout of discrete block component icon).
Information
Model predicting the state of the blinds with the outdoor temperature.
Dynamics
When the space is unoccupied, the blinds are always down. When the
space is occupied, the lower TOut, the higher
the chance that the blind is up.
References
The model is documented in the paper "Haldi, F. and Robinson, D., 2008. On the behaviour and adaptation of office occupants. Building and environment, 43(12), pp.2163-2177."
The model parameters are regressed from the field study in eight Swiss office buildings in 2006.
