Energy certification of buildings is promoted by the current energy policy of the European Union. The Building Energy Performance Regulation was published in 2002 and since then several studies have been conducted in European countries. The lighting energy requirements of buildings are determined using the methodology described in the European Standard EN 15193 which takes into account the required visual comfort conditions. In Turkey, a new national calculation methodology, Building Energy Performance-Turkey (BEP-TR), has been developed based on Turkeys particular conditions. In this paper, the BEP-TR lighting module is briefly described. Its use is then demonstrated by the prediction of the lighting energy requirements for a prototype primary school classroom in different locations in Turkey. The paper also performs a sensitivity analysis of the BEP-TR methodology on the developed daylighting and electric lighting design alternatives.
