SYSTEM AND METHOD FOR THE OPTIMIZATION OF RADIANCE MODELLING AND CONTROLS IN PREDICTIVE DAYLIGHT HARVESTING

SYSTEM AND METHOD FOR THE OPTIMIZATION OF RADIANCE MODELLING AND CONTROLS IN PREDICTIVE DAYLIGHT HARVESTING

Publication #: US 2017/0192406 Publication Date: 06-Jul-17
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, including diffusion characteristics of the materials between environments.

In the context of a predictive daylight harvesting system data values are input regarding a plurality of variable building design parameters. The effects on a building’s environmental characteristics are calculated based on the data values regarding a plurality of building design parameters. At least one of the data values is changed regarding variable building design parameters. The effects on a building’s environmental characteristics are recalculated based on the data values regarding a plurality of building design parameters building heat balance.
