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:
Energy management practices include use of an extensive Siemens BMS to implement nighttime setbacks, room scheduling, and temporary heating/cooling options to allow partial use over breaks or off-peak times. Lighting sensors are also employed in a wide variety of campus spaces.
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. Past and recent projects include the retrofit of various Athletics facilities and the Science Center to switch incandescents into LED light fixtures.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The PPR Apartments 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 and retaining conditioned air through leak prevention and increased insulation. Additionally, the College has begun work to transition all heating and cooling on campus to a geoexchange system. Mention geoexchange system for Whittier hall, working on transitioning enetire system to geoexchange.
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:
