Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 82,474,009.02 Kilowatt-hours | 281,401.32 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 7,033.71 Kilowatt-hours | 24.00 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Wherever and whenever applicable and feasible, the university conserves energy and improves campus energy efficiency. The university aligns its plans, practices, and procedures with the campus environmental stewardship goals and the campus Environmental Stewardship Action Plan. JMU Policy 1704 ( https://www.jmu.edu/JMUpolicy/policies/1704.shtml) outlines procedures for individuals to take to maintain and save energy on campus.
A brief description of energy use standards and controls employed by the institution:
In order to conserve energy, JMU employs several strategies to operate systems efficiently: 1) Scheduling: During unoccupied hours, buildings are placed into standby condition where the HVAC system is effectively turned off. 2) Sensors: A combination of motion, carbon dioxide, and occupancy sensors allow JMU to control the amount of outside air brought into buildings, e.g. by turning off the HVAC system when a student opens the window in a residence hall room. 3) Variable Frequency Drivers: These are also being installed on motors throughout campus allowing motors to operate at a speed proportional to power need.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Beginning in 2011, the university began a widespread effort to retrofit LED lighting across campus as funding became available. A total of approximately 10,000 LED lights have been installed across campus resulting in an estimated reduction in electricity usage of over 2,000,000 kWh per year. Additionally, the university completed a comprehensive Dark Sky Study in 2016 that evaluated over 2000 exterior light fixtures across campus and determined their level of light pollution. The study found that 97% of the fixtures on campus are classified as either Cutoff or Full Cutoff by the Illuminating Engineering Society (IES). The study provided recommendations for replacing the "worst offender" lights on campus with higher efficient lighting that would reduce their contribution to light pollution.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
In the renovation of Wayland Hall, a LEED Certified, Platinum-level building, JMU installed 32 wells as part of a “geothermal” ground source heat exchange system, using a water-to-water heat pump. This system was estimated to save 39% on energy usage in comparison to an average building of that size and use at that time.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
JMU Policy 1701 requires that all electric products purchased by JMU meet the US EPA Energy Star certification. JMU’s Building Automation team also performs retro-commissioning by verifying all sensors and controllers related to the HVAC and control system will be able to improve temperature management, outdoor air volume adjustments, and equipment scheduling.

Data source(s) and notes about the submission:
Per STARS guidance, valid data for this credit must be within the three years prior to the anticipated date of submission. All data entered for the performance year is from FY 2018-2019. This year was chosen due to effects of the COVID-19 pandemic in FY 2019-2020 and FY 2020-2021. Therefore, figures for gross floor area of building space and energy intensive spaces differ from those of PRE-4 which uses FY 2020-2021.
Gross floor area of building space entered for this credit is based on data provided from the energy budget and is based on utility data.
Data for degree days retrieved from Energy Star Portfolio Manager.
