Start Date End Date
Performance Year Jan. 1, 2017 Dec. 31, 2017
Baseline Year Jan. 1, 2010 Dec. 31, 2010

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
The building energy consumption baseline was adopted to correspond with the baseline for the university's Strategic Energy Plan reports to the Maryland Department of General Services.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 15,129,960 Gross square feet 14,092,946 Gross square feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.18 MMBtu per square foot 0.19 MMBtu per square foot
Source energy 0.27 MMBtu per square foot 0.25 MMBtu per square foot

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
Through education and outreach efforts described in the Engagement section, students and employees are encouraged to: Take advantage of natural light, and turn off lights when they’re not in use; Turn off computers and monitors when not in use; Look for Energy Star rated and EPEAT certified electronics; and Unplug electronics when not in use.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
There are temperature setpoints for occupied and unoccupied hours through the building automation system in many buildings. Many buildings also have occupancy sensors.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lights are used in appropriate locations. In the XFINITY Center, compact fluorescent fixtures, metal halide recessed down-lights and surface cylinders, and other various lights were recently replaced with LED lamps. The XFINITY Center is home to Maryland's athletics administration, the basketball teams, the gymnastics team and also serves as a campus site for university special events and community events.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
There are three buildings on campus that rely on geothermal systems for some of their heating and cooling needs.

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
The recipient of the EPA’s 2005 Energy Star Award, the university’s Combined Heat and Power Plant was completed in 2003. The system produces all of the steam required for heating and in some cases cooling for the university. The plant is capable of producing up to 90 percent of the university’s electric demand in the winter and around 50 percent of the summer demand. Consisting of two gas-fired combustion turbines, one steam-driven electric turbine, and two heat recovery steam generators, the system operates at efficiencies of around 70 percent, significantly higher than like-sized independent steam boilers and electric generators. The system requires approximately 16 percent less fuel than typical purchased electricity with separate steam generation, resulting in a reduction of nitrous oxide, sulfur dioxide, and roughly 53,000 tons of carbon dioxide annually.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
The President's Energy Conservation Initiative (announced in 2014) is being implemented across campus to reduce electricity consumption by 205 between 2015 and 2020. Facility managers from departments across campus meet monthly and collaborate to move this campus-wide initiative forward. The Facility Performance unit in the Department of Engineering & Energy is responsible for evaluating facilities operations with an eye to maximizing energy efficiency. This is accomplished by overseeing commissioning of new construction to ensure proper turnover as well as re-commissioning of existing facilities through building data analysis. This unit is also responsible for expanding and maintaining the campus building automation system to assist in optimizing facilities’ performance.
