Average Daylight Factor (ADF) Calculation

Average Daylight Factor (ADF) calculations demonstrate how the level of light inside a building compares to the level of light outside and estimates how much light will actually reach occupants of a building.  ADF calculations are a common requirement for the BREEAM assessment.

BREEAM Health and Wellbeing criteria stipulates the minimum daylight requirements within occupied areas of a building. To achieve the desired credit, daylight analysis is carried out using software to simulate the amount of available daylight within an occupied space.
