Abstract
This paper presents the validation of two daylightdynamic predictive metrics, obtained through simulation withDaySim 3.2 tool: Daylight Autonomy (DA) and ContinuousDaylight Autonomy (DAC). To that effect, a validation protocolis developed, in which the annual results of the predictivesimulation model are compared to the illuminance valuesmeasured during a whole year into an existing test cell, locatedin Seville (Spain), which is used as a reference. After trials itwas found that, for three illuminance thresholds of 100, 250 and500 lux, the mean difference of daylight autonomy betweenmeasurements and dynamic simulations is lower of 2% with astandard deviation of 6.8%, and the mean difference forcontinuous daylight autonomy is 1.0% with a standarddeviation of 4.9%. It is concluded that the use of these twometrics by calculation with DaySim tool is adequate forsmall-sized rooms with one window, located in theMediterranean area. The exposed methodology allows tovalidate the use of these indicators in rooms with variable size,window size and location, so further investigation is required.
