PREDICTIVE DAYLIGHT HARVESTING SYSTEM

摘要

In an example, an expected sky condition is calculated for a geographic location, a time of day, and a date based on a mathematical model. A predicted distribution of direct and interreflected solar radiation within the environment is calculated based on the expected sky condition. Measurement data from one or more photosensors is obtained that provides measurements of an initial distribution of direct and interreflected radiation within the environment, including radiation from solar and electrical lighting sources. A target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting is determined, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, to achieve the target distribution of direct and interreflected radiation within the environment. Output parameters are set to one or more devices to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment.

1. A method performed by a predictive daylight harvesting system, the method comprising:
obtaining one or more input values identifying a geographic location, a time of day, and a date, and a target distribution of direct and interreflected radiation within an environment that includes a combination of radiation from solar and electrical lighting sources; calculating an expected sky condition for the geographic location, the time of day, and the date based on a mathematical model, the mathematical model incorporating and/or previously trained on historical weather data; calculating a predicted distribution of direct and interreflected solar radiation within the environment based on the expected sky condition; obtaining measurement data from one or more photosensors measuring an initial distribution of direct and interreflected radiation within the environment; determining, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, a target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting to achieve the target distribution of direct and interreflected radiation within the environment; and setting output parameters to one or more devices controlling admittance of solar radiation into the environment and/or controlling the electrical lighting to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment.
