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 times and notes are left to individuals who have left items on. Since 2012 we have held a student energy conservation contest, and in 2016 added a faculty staff competition. Both create awareness through positive messaging and friendly competition. Energy program 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 an energy conservation "tool box" is available for check out at the main library.
A brief description of energy use standards and controls employed by the institution:
W&L's energy standards including 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.
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.
