What is Daylight Analysis?

Daylight analysis simulates how natural light moves through a design across days and seasons, measured with metrics like spatial daylight autonomy (how much floor area is usefully lit) and annual sun exposure (glare and overheating risk).

In practice

Once a specialist study, daylight simulation now runs in near real time inside early design tools, shaping massing and window decisions when they are still cheap to change.
