Had a great conversation with Jason Burbank at the Phys Plant this morning. He is the Campus Energy Engineer and is very open to being helpful on this project. He directed me to the spreadsheets available on the Phys Plant web site linked here.
Turns out a company called Johnson Controls has already done an energy audit and is under contract to make energy usage improvements. I'll need to continue the conversation but Jason looks to be a great contact point for our project.
