What are Daylighting Calculations?
Daylighting Calculations are produced by our assessors to determine the amount of natural light that is anticipated to penetrate a room. Factors such as the size of the opening, reflectivity of surfaces, and view of clear sky from a window will all affect the daylight factor in a room.
Awardable Credits

Another credit can be met where a minimum of 80% of the kitchen, lounge, dining room and home office receives direct light from the sky. |
