EN Criteria for Evaluation of Daylight in Interiors

Abstract:

Daylighting in buildings is commonly designed and evaluated after the Daylight Factor criterion which is required also by the Slovak standard STN 73 0580. The model of the overcast sky representing the worst daylight conditions is the basis of all standard daylight calculations in many countries. Currently, the prEN standard Daylighting of buildings is elaborated by the CEN TC 169 WG11. A new climatological criterion for evaluation of daylight provision is proposed to reflect various luminous conditions in European localities. This paper informs and discusses the concept of the new standard and presents an example of daylighting evaluation in an interior applying STN and new EN criteria.
