Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 51,328,392 Kilowatt-hours | 175,132.47 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 347,225 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
FY 2005 has been used as the baseline on our past four reports.

Optional Fields

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Under the "Reduce the Juice" initiative, we promote the embrace of energy-conserving practices through these teachings:
Power down and unplug electronic devices.
Employ power strips, switching them off once devices have been powered down.
Embrace layered clothing to minimize the need for space heaters.
Centralize the use of devices in shared spaces (like coffee makers, mini-fridges, microwaves, etc.).
The "Flip the Switch" campaign advocates for the deactivation of lights when not in use:
Ensure lights are switched off when departing your office or vacating communal spaces (e.g., copy rooms, break rooms, etc.).
Opt for natural lighting when available.
Power down task lighting (such as desk lamps, standing lamps, etc.) when not needed.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LEDs have become the norm for both indoor and outdoor lighting, accompanied by lighting control systems, in the realm of new building projects and refurbishments. As the need arises to replace lights, NAU will only be installing LEDs. The methods of control are adapted to suit the specific building category and the preferences of its occupants. Additionally, there's the option to transition your office or classroom lighting to LEDs immediately upon request.
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.
