How thoughtful spatial planning maximizes daylight and reduces artificial lighting loads.

Keep primary habitable zones (living room, bedrooms) on external walls with direct fenestrations.

Natural daylight drops off significantly beyond 15-20 ft from window openings without lightwells.

Wider, taller lintel heights bring light deeper into the floor plate than low-set narrow windows.

Use fluted glass partitions or high transom windows to illuminate dark internal hallways.

Never position wardrobes, tall cabinets, or dark solid partitions adjacent to primary windows.

East windows offer gentle morning sun; North windows provide glare-free, uniform daylight all day.
