Clear Sky Solar Exposure Color Legend Explained

Clear Sky Solar Exposure is a metric that quantifies the amount of direct sunlight an area receives as a percentage over a specified time period, assuming ideal, cloudless sky conditions. Like other thermal comfort metrics, solar exposure is defined over a season and time of day such as morning, afternoon, or evening. The percentage is calculated by assessing the proportion of time during the given period that the area receives unobstructed sunlight. A 100% value means the area is exposed to direct sunlight for the entire time period, while a lower percentage reflects periods of shade from the built environment.
