Abstract:
1. A method performed by a predictive daylight harvesting system, the method comprising: receiving data values regarding a plurality of variable building lighting design parameters, including luminaire locations and illumination levels; calculating effects on a building's environmental characteristics based on the data values regarding the plurality of variable building lighting design parameters; changing at least one of the data values regarding the plurality of variable building lighting design parameters; selecting building lighting design parameter settings for the variable building lighting design parameters to maximize energy savings while maintaining selected occupant requirements for the building's environmental characteristics, including at least selected occupant requirements for lighting; measuring actual solar insolation and fine-tuning the selected building lighting design parameter settings to maximize energy savings while maintaining the selected occupant requirements for lighting; analyzing a combination of historical weather data, in situ daylight measurements over time and current weather predictions, and determining an optimal strategy for predictive daylight harvesting that maximizes energy savings while maintaining the selected occupant requirements for lighting; analyzing occupant behavior, based on input from occupancy event sensors and personal lighting controls actions, and further determining the optimal strategy for predictive daylight harvesting that maximizes energy savings while maintaining the selected occupant requirements for lighting based on predicted occupant behavior; and interacting with a building's lighting control system and implementing the optimal strategy for maximizing energy savings while maintaining the selected occupant requirements for lighting.
