The table below shows how recommendations according to the European Standard are met in all rooms of the house with levels far exceeding the target recommendations. With regards to the Active House Specifications, almost all living spaces achieve the highest class for daylight performance (i.e. higher or equal to 5% Daylight average), and two rooms meeting the second class (i.e. higher or equal to 3% Daylight average).
European Daylight Standard
Maison Air et Lumière was evaluated according to the European Daylight Standard, which is a new EU legislation awaiting formal voting in CEN before final implementation. If approved, Europe will have its first daylight standard in spring 2018, which will specify the minimum recommendations for daylight and view, as well as the duration of sunlight exposure within residential buildings.
The proposed European Daylight Standard suggests to change the basis of daylight evaluations from simple glazing ratio requirements to `daylight factor targets' based on the occurrence of outdoor illuminance levels from recorded climatic data.
Maison Air et Lumière demonstrates that good daylight conditions can lead to significant savings on electricity use for lighting during daytime and provide the occupants with a high level of satisfaction.
A paper by VELUX researchers was presented at the Lux Europa 2017 conference held in Ljubljana, Slovenia, on September 18-20.
