"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 88,172.50 MMBtu 63,754.84 MMBtu
Electricity from on-site renewables 275.40 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 75,579.40 MMBtu 53,442.95 MMBtu
Total 164,027.30 MMBtu 117,197.79 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2006 June 30, 2007

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):

2006 is the first year for which we have complete, accurate utility data, including electricity and natural gas.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 3,026,463 Gross square feet 1,392,472 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 0.05 MMBtu per square foot 0.08 MMBtu per square foot
Source energy 0.12 MMBtu per square foot 0.18 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 5,074 Degree-Days (°F)
Cooling degree days 686 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 42,347 Square feet
Healthcare space 3,909 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
3,297,763 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
8.64 Btu / GSF / Degree-Day (°F)

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):

UCCS Office of Sustainability has two programs to help shift individual attitudes and practices: Greening of the Office (GOTO) and Green Labs. GOTO involves an assessment of a faculty/staff's current use which is then used to help them learn where they can improve on being more sustainable. Green Labs is similar; however, it evaluates labs only. Green Labs is currently focusing on increasing the temperature of freezers in labs.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Our campus has a BAS system in place to turn off air handlers during the night in campus buildings according to class schedule. For all new buildings, occupancy and vacancy sensors are utilized, and some daylighting controls as well.

For our climate, we have established 71 degrees F for our wintertime temperature setpoint and 77 degrees F for our summertime temperature setpoint.

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

We have retrofitted many of the parking lot lights with LED as well as walkway lights. New buildings use almost exclusively LED. Large scale retrofits within buildings are starting to take place with all of the Library undergoing a retrofit to LED in December 2017.

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):

Several energy audits have been conducted by Colorado Springs Utilities. Based on these, retrofit projects are selected for each year depending on budget. For 2017, all of the lighting in the library will be changed to LEDs. UCCS has an Energy Star appliance policy. Procurement Services Center for the system works to select energy efficient copier contracts. IT selects EPEAT Gold, Energy Star computers. Energy performance is included in capital renewal projects as much as possible.
