Information

Model predicting the state of the blinds with the solar altitude and occupancy.

Dynamics

When the space is unoccupied, the blinds are always down. When the space is occupied, the lower the solar altitude is, the higher the chance that the blind state will be changed, either being turned on or turned off.

References

The model is documented in the paper "Zhang, Y. and Barrett, P., 2012. Factors influencing occupants’ blind-control behaviour in a naturally ventilated office building. Building and Environment, 54, pp.137-147."

The model parameters are regressed from the field study in an office building in Sheffield, England.
