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

Reduce the Juice:
This campaign encourages the adoption of energy-saving habits by teaching to:
-Turn off and unplug electronic devices
-Use a power strip and turn it off after devices have been shut down
-Avoid the use of space heaters by dressing in layers
-Use devices in common areas (coffee pot, mini fridge, microwave, etc)

Strive for 5: Flagstaff is located in the high desert, meaning water is a precious commodity. The "Strive for Five" campaign encourages campus to strive for 5 minute showers and be more aware of the impact excessive water use has on the surrounding environment.

Flip the Switch:
This campaign encourages the turning off of lights when not in use:
-Turn off lights when leaving your office or unoccupied common areas (copy room, break room, etc)
-Use natural lights when possible
-Turn off task lighting (desk lamps, standing lamps, etc) when not in use


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

e1Our recent NORESCO energy conservation measures project sets temperature standards of 69-76 for the majority of NAU buildings.


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

LEDs are now the standard for interior and exterior lighting along with lighting control systems for new constructions and renovations. The control strategies vary based on the type of building and occupant requests.


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

Some buildings use passive solar heating for water or air.


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