Model predicting the state of the lighting with the minimum illuminance on the working plane and occupancy.
In this model, it was found people tend to switch on the lights-if needed- only at times when entering a space, and they rarely switch off the lights until the space becomes completely empty.
The probability to switch on the lights upon arrival would depend on the minimum illuminance level on their working plane.
The model is documented in the paper "Hunt, D.R.G., 1980. Predicting artificial lighting use-a method based upon observed patterns of behaviour. Lighting Research & Technology, 12(1), pp.7-14."
The model parameters are regressed from the field study in 10 offices in Germany from Mar. to Dec. 2000.
