Abstract: Systems and methods for deriving and modifying personal preferences related to at least one controllable lighting network are disclosed. The systems include a processor that can be used in conjunction with a personal communication device and a preferences database. The processor is used to detect an identifier for a user, a plurality of adjustments to the at least one controllable lighting network requested by the user, and a context corresponding to each of the plurality of adjustments. The processor in some such systems has an associated local memory to store the plurality of adjustments, corresponding contexts, and the identifier of the associated user. The processor is further used to analyze the plurality of lighting adjustments and the corresponding contexts. Based on the analysis, the processor identifies a correlation between the plurality of adjustments and the contexts, and create at least one personal preference rule associated with the user identifier based on the correlation.

Abstract: 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.
