The potential of daylight in a room is expressed as how often during the year, daylight allows to exceed the illuminance level required to perform a task. This depends on the task, the characteristics of the room and its fenestration system, and on the luminous climate of the site. With SODALIGHT producing this information all over Europe, is fast and simple.

SODALIGHT allows you to define the characteristics of a rectangular room and its fenestration system, to compute overcast sky daylight factors, define a site by its latitude and longitude, specify the required illuminance level and produce the daylight potential information. It is so flexible that you can compare various configurations in a few minutes. An extensive help is provided with the applet, just click on the Help tab.
