Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 372,236 MMBtu | 281,413 MMBtu |
| Electricity from on-site renewables | 44 MMBtu | 24 MMBtu |
| District steam/hot water (sourced from offsite) | 489,141 MMBtu | 390,802 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 266,762 MMBtu | 152,015 MMBtu |
| Total | 1,128,183 MMBtu | 824,254 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2015 | June 30, 2016 |
| Baseline Year | July 1, 2008 | June 30, 2009 |

Optional Fields
---
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):
---
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
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 reduce the amount of outside air brought into buildings in the case of CO2 sensors or turn off the HVAC system when a student opens the window in a dorm room. 3) Variable Frequency Drivers 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 over 2100 LED lights have been installed across campus resulting in a estimated reduction in electricty usage of over 750,000 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 platinum certified building, JMU installed 32 wells as part of a “geothermal” ground source heat exchange using a water-to-water heat pump and this new system is estimated to save 39% on energy usage in comparison to an average building of that size and use.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---
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):
JMU’s 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 system and with the current control system upgrade underway, will be able to improve temperature management, outdoor air volume adjustments, and equipment scheduling.
