Novel Miniaturized Indoor Glare Sensor for Integrated Control of Shading and Lighting System

One fifth of the electricity consumption of Swiss buildings is due to electric lighting. We propose a patented automatic method to mitigate this electric consumption in non- residential buildings by prioritizing the daylight while guaranteeing the visual comfort of the occupants. A new sensor, called High Dynamic Range (HDR) Vision sensor, is introduced to the building automation system to intelligently control the shading and lighting system of the LESO solar experimental building on EPFL campus. This article will provide an overview on the proposed solution and details on how the sensor is calibrated, how its measurements are transformed to glare indices and finally how it is integrated into the building automation system (KNX) of the building.
