Daylight autonomy meaning
WebDaylight Autonomy (DA) was the first of a string of annual daylight metrics, now commonly referred to as ‘dynamic daylight metrics’. It is represented as a percentage of annual daytime hours that a given point in a space is above a specified illumination level. Continuous Daylight Autonomy; Useful Daylight Illuminance; Daylight Saturation … Continuous Daylight Autonomy; Useful Daylight Illuminance; Daylight Saturation … WebIn addition, daylight autonomy is the most usual dynamic definition, because it estimates the energy consumption of on–off electric lighting systems depending on weather conditions. However, there is no link between static and dynamic metrics, because both concepts are based on different variables.
