A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

We've expanded electrical metering to all dorms and run energy conservation competitions a few times a year.


A brief description of energy use standards and controls employed by the institution:

Temperature settings are centrally controlled by Facility Services. In 2009, we instituted a new energy-saving HVAC policy as well. During the academic year, academic buildings and public spaces like the Warch Campus Center will be maintained at a target temperature of 68 degrees (+/-2 degrees). In the summertime, academic buildings will be maintained at a target temperature of 76 degrees (+/-2 degrees).


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

LED light replacement is now a routine part of building upgrades and renewal. All new exterior lighting is LED.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

None


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:

We have commissioned an energy audit and building envelope study and have identified a number of opportunities for energy savings. We have not yet implemented any of these.
