Abstract
The entry into force of the first European standard dealing with daylight is very good news. However, the objectives set by this standard in terms of daylight provision are quite demanding and the consequences on the design of buildings are far from neutral. Based on simulations conducted with the DIAL+ software, the study focuses on the Daylight Provision criterion and looks at the influence of localization (latitude). The work consists of the evaluation of a 2 case-studies and analyses the results obtained for 4 locations in Europe. The aim is to put in perspective, on the one hand, the daylighting performance and, on the other hand, the induced energy consumption in terms of heating, cooling and electric lighting. This gives a better idea of the consequences of this Standard on the overall energy performance and allows to question the objectives set by the standard
