Daylight Factor
A mobile daylighting design puzzle: drag to size and position a window on a room cross-section and watch illuminance contours redraw live across the floor. Head height, room depth, and surface reflectance all matter; a light shelf can be added to boost rear illuminance. Twelve rooms each set a uniformity and minimum rear-illuminance target that conflicts with glare. Share your finished illuminance plot with the Eazo community.
