WebSpatial Daylight Autonomy (SDA) A measure of annual daylight sufficient for a given area, reporting a percentage of floor area that exceeds a specified illuminance level (e.g., 300 lux) for a defined analysis period (10 hours/day, 365 days/year). For LEED® projects, scoring varies by building type; higher scores equals more credits. Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (with the unit lumen) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance is inversely proportional to area when the luminous flux is held constant. g mol to gramsWebSchneider Electric USA.
