Documentation to support the performance year energy consumption figures reported above:
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Students learn about individual behavior changes in a class called Sustainability As A Lifestyle. They also learn about best practices in housing during the energy competitions, and throughout the year at various sustainability education events.
A brief description of energy use standards and controls employed by the institution:
University uses a BMS (Building Management System) for controlling startup, shutdown, setback, occupied and non-occupied temperature set points.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The university has been researching and installing LED lighting for the past 5 years. To date we have installed LEDs into several buildings, some tied to motion sensors. For exterior lighting the university has invested over .5 million dollars into installing over 800 LEDs for parking ramps, lots and street lighting.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Solar panels on the roof of an athletic building capture solar energy to help heat the water source in the locker rooms.
A brief description of co-generation employed by the institution:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Recommissioning is done on a case by case basis. It is done by troubleshooting mainly and is not a stand-alone program. However the university has recommissioned some buildings by a third party to provide some energy conservation measures.
