A brief description of when and why the energy consumption baseline was adopted:
Mason's fiscal year runs from July 1st to June 30th of the following year in conjunction with its academic year. Fiscal year 2006 was chosen as a baseline since Mason signed the American College and University President's Climate Commitment in 2007.
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 | 0.17 MMBtu per square foot |
| Baseline year | 0.12 MMBtu per square foot | 0.24 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:
Mason's Office of Energy Management holds an annual event to encourage all students, staff, and faculty on the Fairfax campus to power down their non-critical devices. The Lights out - Power down! event aims to reduce the university's power load by 2,000 kilowatt in one hour. In addition, Mason's Housing and Residence Life provides reminders to residents to turn off, set thermostats, and take shorter showers.
A brief description of energy use standards and controls employed by the institution:
George Mason University has set temperatures for hot and cold weather and installed wall mounted and ceiling mounted occupancy and vacancy sensors throughout its campus, including seldom used areas such as restrooms, conference rooms, and stairways.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
At George Mason University LED technology has been installed in the majority of the outdoor lighting systems on the Fairfax and Prince William Campuses. The lighting systems include road ways, parking lots, walkways and parking garage lighting systems.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
In Exploratory Hall on Mason's Fairfax campus, daylight harvesting systems were used in the labs and the building uses a screen to evenly distribute light into the interior space to reduce heating and cooling needs and loads. Passive solar heating was also incorporated into the design of the new Health and Human Services building.
A brief description of co-generation employed by the institution:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Since FY05, Mason has initiated two Energy Performance Savings Contracts with Siemens Industry, Inc. totaling 16.7 million dollars. The 40 energy improvement measures yield 2.5 million dollars in savings annually. The Energy Management Department also used funds returned from the curtailment
program to complete a thermal blanket insulation project that will yield savings of 2.5 million dollars over a 15 year period and a payback of 13 months. The reduction of GHG emissions for all three projects is 20,505 metric tons of CO2 annually.
