A brief description of when and why the energy consumption baseline was adopted:
In 2001, there were a group of interested and progressive faculty members that wanted to start benchmarking our data. And it has been maintained since then by our energy manager.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
Site energy | Source energy | |
Performance year | 0.09 MMBtu per square foot | 0.14 MMBtu per square foot |
Baseline year | 0.12 MMBtu per square foot | 0.19 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Our sustainability work study students conduct workshops for the dorm RAs to then educate their students within a dorm on practices such as energy efficiency and how to report over or underheated spaces, reduction in hot water use, and so on.
A brief description of energy use standards and controls employed by the institution:
We have just installed Honeywell building sensors and controls in all of our major buildings, so that we may now employ automatic shutdown, and temp control at night or vacations. It also lets us see data on energy use from each building - something which is relatively new to us.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
We are swapping out with T8s and LEDs as existing bulbs fail. Our two newest buildings have 100% LED lighting. This upcoming year, we will engage in a campus-wide LED retrofit.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
We have been focusing on daylighting in our newest buildings, and heat reclamation upgrades to our ventillation in our rennovations.
A brief description of co-generation employed by the institution:
We do not have CHP on campus.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
We are in the midst of an audit of our science lab hood ventilation, hoping to replace and upgrade with more efficient units.
