stereographic projection onto site, which shows how the buildings and obstacles obstruct the summer sun. During the summer, this site receives sunlight during most times of day.

the orange color overlayed on the summer sun stereographic projection shows how winter sunlight on the site differs from summer sunlight. During the winter, Ruffin hall and Culbreth cast shadows on the site other than during a gap around midday. solar+ortho+stretch

 

This orthographic projection shows that during thes summer months, the site recieves optimal sunlight for most of the day. During the winter, the buildings and trees block sunlight save for a small window of time between noon and 3pm. Luckily for the winter months, the trees that are directly behind Campbell hall aren’t as bad of a problem because their leaves have all fallen.

This wind rose diagram shows the site during the summer. In Charlottesville during summer months, the most constant and strong winds are the warm winds from the southwest, which become funneled and accelerated around buildings and towards the site. Cooler winds from the Northeast are also funneled through buildings towards the back of the site.

During winter months, wind is a lot bigger of a problem for this site. The Northwestern winds are blocked by the parking garage, but the Southern winds and Northeastern winds are magnified by the curve of Culbreth theater and accelerated by the Venturi effect through the gaps in buildings. Sheilding from the wind in winter months is a major design necessity for this specific site.

This chart shows Charlottesville during July and August, the hot summer months. The design strategies employed here are high thermal mass, sun shading, natural and fan ventilation, and redirecting internal heat gain. Ventilation and sun shading are especially influential on how comfortable the space is in the summer.

In the winter months, different strategies have to be employed in order to make the space comfortable. This chart shows January and February from the hours of 7am to midnight. Harnessing solar heat, retaining it, and blocking wind are the most crucial aspects of designing for the winter.
