A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
There is signage around campus that encourages individuals to turn lights off after they leave a room. There are also campus-wide emails that remind students who live on campus to unplug all electronic devices and turn off all lights when leaving for extended breaks.
A brief description of energy use standards and controls employed by the institution:
We practice rigorous energy management with a Siemens DDC night time set backs, room scheduling via the academic calendar and some level of light control
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All new lighting is specified to be LED unless impractical or special purpose. Some recent projects include the retrofit of Athletics facilities, including the Lamb Miller Fieldhouse and Ware Pool, which switched the incandescents into LED light fixtures.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The PPR Apartments, a new residential hall constructed since our previous report, is connected to a geothermal energy system. Singer Hall, another new academic building, was built with Passive Design & Envelope Optimization, which combine to put less demand on the HVAC systems by inviting solar gain in the winter, preventing solar gain in the summer, and retaining conditioned air through leak prevention and increased thermal insulation.
A brief description of co-generation employed by the institution:
None.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
All replacement appliances are specified to be Energy Star rated.
