An architect is working with a developer to determine which of three available sites should be the preferred location for a new office building that will primarily utilize passive energy systems. All three sites are located in a cold, northern climate with winter winds predominantly from the north and west.
Site descriptions:
Site A: Located at the top of a hill; small vegetation and brush; expansive views in all directions.
Site B: Located along a river; heavily wooded area on the north side; coniferous trees shading the southern face of the building.
Site C: Located on a rocky, south-facing slope; wooded on the eastern edge; native grasses on southern boundary.
Primary goal: maximize solar energy potential while maintaining winter wind protection.
Which site should be selected?
