Definition
Daylighting designs openings, courtyards, light wells and louvres to bring daylight into interiors while controlling heat and glare. In the Saudi climate indirect light from the north or through courtyards and louvres works best.
Why it matters on a project
It cuts lighting energy and improves comfort and health, but too much direct sun raises the cooling load and causes glare.
Common mistake
Enlarging windows for more light without shading, so glare and heat come in and blinds stay closed all day.
Frequently asked questions
Which window orientation is best in Saudi Arabia?
North gives steady light without much heat; west is the hottest.
Do courtyards help daylighting?
Yes, they bring light and air into the middle of the building without opening facades to sun and street.
