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 | 25,421,906 Kilowatt-hours | 86,739.54 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 9,932 Kilowatt-hours | 33.89 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 145,738 MMBtu |

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
W&L has a comprehensive campus wide energy conservation program. Energy policy includes broad university and specific department wide expectations, but also specifies expectations for individual actions, including turning off computers/monitors/printers in work spaces nightly. Regular audits are performed during unoccupied to verify system performance. Since 2012 we have held a student energy conservation contest, which creates awareness through positive messaging and friendly competition. Sustainability staff speak regularly at departmental staff meetings, and student fora ranging from orientation for Residential Advisers to environmental science classes. Energy information and reminders are shared regularly through social and campus media and annual targeted poster campaigns, and user friendly tips are presented on the "How-To" section of the Sustainability Office website: https://my.wlu.edu/sustainability/sustainability-how-to. W&L's energy dashboard,go.wlu.edu/PowerTrip, offers the campus community real-time electricity data and allows a direct, real-time view of how operations and individual behaviors impacts energy use.
A brief description of energy use standards and controls employed by the institution:
The University has implemented ASHRAE Guideline 36 high performance sequences of operations. W&L's energy standards include time of day HVAC setback schedules in virtually all non-residential campus buildings, customized weekly to match actual, scheduled, building occupancy. Scheduling is implemented through two BAS systems (Trane and Siemens) and in smaller buildings, through local thermostat programming control. Efficiency (economizing, HW setpoints, CFM etc) are monitored regularly through BAS systems. Lucid BuilingOS is used for daily setback verification and daily electricity trending, as well as for broad constituent education and highly targeted information campaigns to students living in sub-metered campus housing. The university also employs specific temperature setting standards.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The University is systematically retrofitting existing campus facilities with LED lighting, and LED systems are standard for renovations and new construction. Motion sensor and daylight sensor lighting is deployed where appropriate and local signage is complimented by frequent awareness campaigns through social media and presentations to targeted constituent groups.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
EnergyStar appliances are required by the University Energy Policy. New capital equipment purchases are reviewed using a life-cycle cost analysis, typically favoring higher efficiency options.
