The location of a building affects architectural shadow because the position of the building in relation to the sun determines the angle and length of shadows cast by the building. The orientation of the building, the height and shape of surrounding structures or terrain, and the time of day and season all affect the size and shape of shadows. For example, buildings located in hot climates where sunlight is intense may have deep shadows that protect windows from the sun and reduce solar gain, while buildings in cooler climates may be designed to maximize solar gain, with fewer and smaller shadows. Additionally, buildings located in urban areas may cast longer shadows due to the height and density of surrounding structures, which can impact nearby buildings or public spaces.
