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

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

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

The University is proactively upgrading existing lighting to LED. Lighting retrofits have recently been performed in academic buildings, athletic facilities, and parking garages.


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

The University contracts with the City of Boise to use district geothermal water as a heat source for eleven campus buildings. The City administers the nation’s largest geothermal district heating system. Geothermal water supplies heat to building hydronic loops via plate and frame heat exchangers. Generally the high-temperature resource is used directly, but one building has a “cascade” arrangement where low-temperature return water from an adjacent building supplies a water-source heat pump loop. Geothermal water is furnished as an interruptible resource so backup heat is required for each building.


A brief description of co-generation employed by the institution:

The University does not currently employ cogeneration / CHP technologies, but intends to evaluate the feasibility of this technology for future central plant upgrades.


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Lighting systems are being retrofitted to LEDs as discussed above. Plans for initiatives such as energy auditing, retro-commissioning, systematic HVAC upgrades, and control sequences review are anticipated to be addressed in a forthcoming Energy Management Plan.
