Finding out the latitude of a site will allow you to calculate what aspect of building design?

Determining the latitude of a site is crucial for calculating solar angles, which directly influence how sunlight interacts with a building throughout different times of the year. Specifically, knowing the latitude helps in understanding the elevation of the sun at different seasons, thus allowing architects to design features such as eaves effectively.

Eaves must be designed with an understanding of how far they should extend to provide shade and block harsh sunlight during the high sun periods, especially in summer. This is important for energy efficiency, occupant comfort, and minimizing heat gain within the building. By calculating the sun's path based on the latitude, an architect can optimize eave lengths for these purposes, which have a significant impact on the building's performance and sustainability.

Other aspects mentioned, like maximum building height, construction costs, and zoning regulations, are less directly linked to latitude. While they are critical components of architectural design, they do not directly relate to the solar considerations that latitude influences.
