Sky view factor is the percentage of the sky not obstructed by obstacles as viewed by an upward facing viewer. In other words, it measures of the fraction of the sky visible from a specific point on the ground. It is used in environmental studies, urban planning, and meteorology to assess the amount of sky visible from a location, which can influence factors like solar radiation, wind patterns, and temperature. In Orbital Stack, sky view factor is calculated as a percentage and considers a clear sky with only a project’s geometry included as possible obstructions. A higher sky view indicates more open sky visibility, while a lower sky view suggests greater obstruction from buildings or other structures. A sky view of 100% would indicate a fully unobstructed view to the horizon in every direction from the point of measurement.
What is it measuring?
The sky view color scale indicates the percentage of visible sky ranging from 0% to 100%.
What options can I specify?
There are no user specifications for sky view, it is entirely geometry driven.
