This sun path study shows the site with its context buildings, which are all on average 50 feet tall, as well as the core of the "public building" which will rise to approximately 90 feet. The red volume indicates the core. Since the public building with its open and airy feel will house the stacks of the library, it is important to determine how the sun will penetrate the site. I decided to raise the public building by 20 feet (as shown in my study model), which also means that the south facade of the public building has an unobstructed sun exposure at noon throughout the year. As indicated in my study model, I placed the core along the south facade to create a "sheltered area" for the stacks north of the core.

The core is also situated slightly east to accommodate a slope that connects the roof to the upper bridge.
An additional reason for placing the core along the south facade is to ensure unobstructed views of the Brooklyn Bridge in the north.
