Natural light and sunshine hours
Definitions
The natural light indicates the number of hours the room is bright enough without the need for artificial light. We consider that this corresponds to a natural light greater than 200 lux.
The direct sunshine indicates the number of potential hours the sun's rays penetrate into the room, under sunny weather conditions.
The values indicated are calculated using an algorithm, audited by CSTB, which takes the following parameters into account:
Surrounding buildings and vegetation, close masks
Historical weather data
Room surface, size and orientation windows
GPS location
