A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space |
14,685,282
Gross square feet

Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.09 MMBtu per square foot | 0.16 MMBtu per square foot |
| Source energy | 0.19 MMBtu per square foot | 0.32 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 5,032 Degree-Days (°F) |
| Cooling degree days | 1,432 Degree-Days (°F) |

| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
Documentation (e.g. spreadsheet or utility records) 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 (e.g. outreach and education efforts):
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The central building operating system operates in all classroom/office/lab buildings.
Where possible (mostly classroom/office) air handlers are turned off at night and on weekends. Otherwise, room thermostats go to a low-energy mode at night and on weekends. Occupancy sensor reduce HVAC use when room is unoccupied, even during normal scheduled hours of operation.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
One parking garage is entirely LED, and one gym was recently converted to high-bay LED. UNL Building Systems Maintenance have begun installing LED retrofits wherever possible in place of incandescent track lighting, HID lamps, and T12 fluorescents.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
