What controls the position of the sun in the project?

The position of the sun in the project is controlled by the project location. This setting provides critical geographic information that influences sun angles, shading, and daylight analysis. When you specify the project location, Revit can accurately simulate sunlight based on parameters such as latitude, longitude, and elevation.

This means that the solar position changes throughout the year and can be used to analyze how the building will interact with sunlight during different seasons and times of the day. For instance, understanding solar exposure can inform design decisions related to passive solar heating, daylight harvesting, and the placement of windows to maximize natural light.

Other options, while important in different contexts, do not directly control sun position. True North is used for alignments and how the building is oriented on the site. Shared Coordinates and Project Coordinates mainly serve purposes related to site referencing and location for the elements of the project, but they don’t influence solar calculations in the same way that the Project Location does.
