The student union building on campus, Eschelmen was due for a retrofit, but my group had to design it for the Austin, Texas climate, and rotated 15 degrees. The Austin climate required our group of three to mitigate high heat and nearly year round humidity, as well as control the daylight for minimal power use while preventing glare. We built a 1/2" study model with interior surfaces as close as possible to the actual designed interior to study light in a diffused daylight simulator (mirror box) as well as Shade for Excel to calculate window sizes with balance point temperature.
