A strategic goal of both the UIUC and the College of Business is to attract and attain the best faculty. In order to do that, it is essential to provide faculty with office space that allows them maximum productivity.
The Business Instructional Facility was the first production rooftop solar PV array installed on a campus building. There are 168 panels with 190 Watts per panel, for a total system size of 32kW. The college has a website that shows the solar output of this system by day, and another site that shows the annual output.
