ONE OF THE REQUIREMENTS TO FAVOR VISUAL COMFORT IN INDOOR ENVIRONMENTS, AS WELL AS TO OPTIMIZE ENERGY EFFICIENCY, REFERS TO GUARANTEEING SUFFICIENT DAYLIGHT. CURRENTLY, SOME STANDARDS DETERMINE SUFFICIENT LIGHT LEVELS TO PERFORM READING-WRITING TASKS. THESE STANDARDS, WHICH ARE BASED MAINLY ON CRITERIA GENERATED IN PLACES LOCATED ABOVE THE TROPIC OF CANCER, PRIORITIZE PRODUCTIVITY OVER PEOPLE?S PERCEPTION. EVEN THOUGH SEVERAL AUTHORS HAVE HIGHLIGHTED THE IMPORTANCE OF CONSIDERING PEOPLE?S PERCEPTIONS IN DETERMINING SUFFICIENT DAYLIGHT ILLUMINANCES, THERE IS NO CONSENSUS ON APPROPRIATE DAYLIGHT LEVELS TO PERFORM READING-WRITING TASKS. IN ADDITION, ALTHOUGH THERE ARE DYNAMIC METRICS FOR THE ANALYSIS OF DAYLIGHT PERFORMANCE, THE MOST POPULAR ONES PROPOSE GENERIC REFERENCE ILLUMINANCES AS SUFFICIENT ILLUMINANCES BUT DO NOT CONSIDER THE PERCEPTION OF PEOPLE. THIS CHAPTER REFLECTS ON THE NEED TO USE DYNAMIC DAYLIGHT METRICS THAT CONSIDER ILLUMINANCES THAT PEOPLE PERCEIVE AS SUFFICIENT. A NEW DYNAMIC METRIC, DADA, IS PRESENTED FOR APPLICATION IN THE TROPICS. THIS METRIC CONSIDERS THE VARIABILITY OF THE PROPORTION OF PEOPLE IN THE TROPICS WHO PERCEIVE A CERTAIN DAYLIGHT LEVEL AS SUFFICIENT DEPENDING ON THE AVAILABILITY OF EXTERIOR DAYLIGHT SO THAT THIS IS CONSIDERED A CONTRIBUTION TO REMOVING THE BARRIERS TO ENVIRONMENTAL COMFORT IN THE TROPICS.
