Abstract

Linking artificial lighting with daylight requires the presence of controls and censors for each room. Apart from the energy saving produced though, this can have significant initial cost implications for the user. This paper presents a method for linking artificial lighting with daylight over a whole building in real time, through a single sensor system. By placing a camera on the top of a building, it is possible to capture a digital image of the sky at regular intervals. Post processing that image can give us an accurate representation of the sky conditions at any given moment. Using that information we can reconstruct any sky condition and predict/simulate the amount of available daylight at any point within a building. By utilizing a database management system, where all the simulation information is stored, we can obtain the simulated daylight levels for each point within a building, for the current sky conditions. This is turn, allows us to control artificial light levels for all the building from a central location.
