Short answer
Daylight Modelling is a computer-based simulation that measures how natural light enters and moves through a building design.
Full answer
Daylight Modelling uses specialised software to predict daylight distribution and intensity within a building. It takes into account factors such as building orientation, window placement, glazing type, shading devices and surrounding obstructions. By running these simulations, designers can optimise layouts to increase natural light, reduce reliance on artificial lighting and improve energy efficiency.
Why this matters
Natural light is directly linked to energy use, comfort and occupant wellbeing. Councils and rating systems such as Green Star often require daylight performance reports to demonstrate compliance.
