The amount of unobstructed daylight received on building facades. Daylight access provides a means to quantify the light reaching the building facade, and subsequently illuminating the interior as it relates to quality of life.

Daylight Access is measured by recording the amount of daylight available on the facade of the generated buildings.Delve then draws vectors from sampled points on the facade at even intervals and traces the vectors to determine if they intersect with the proposed design and existing buildings. A hit percentage is then calculated for all points that resulted in an interaction and averaged by the number of vectors to arrive at the percentage of Daylight Access.

A score of 54% or greater unobstructed daylight suggests an adequate amount of natural light making its way into an interior space for brightness and comfort. Inversely, a score of 20% or less suggests limited natural light for interior space.

Exploring alternative massing layouts and the inclusion of additional building types with a lower FAR is recommended if daylight access is falling to acceptable expected thresholds.
