A brief description of when and why the building energy consumption baseline was adopted:
Student Capstone projects led to the building energy consumption baseline in 2010
A brief description of any building temperature standards employed by the institution:
Offices are set to a minimum of 73 degrees cooling and a maximum of 74 for heat. The majority of spaces conditioned on campus are controlled by our campus energy management system which occupants have little or no control over temperature settings. Temperature in the apartments is controlled by Landlord t-stats that have a minimum setting of 72 degrees for cooling and maximum of 73 degrees for heat.

• All new or replaced exit signs or LED
• All fixtures in the Mood Environmental lab were replaced with LEDs
• All lights in the Commons Servery have been replaced with LEDs
• All lights in Caskey Center rooms 705, 710, 711 and entry have been replaced with LEDs
