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.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	18,684,699.19 Kilowatt-hours	63,752.19 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	53,442.95 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

117,195.14 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

1,392,472 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	July 1, 2006	June 30, 2007

A brief description of when and why the energy consumption baseline was adopted:

---

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.09 MMBtu per square foot	0.17 MMBtu per square foot
Baseline year	0.08 MMBtu per square foot	0.18 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

3.14

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

UCCS Office of Sustainability collaborates with Environmental Health and Safety for the Green Labs program, which includes energy efficiency projects. Green Labs is currently focusing on the temperature of freezers in labs.

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

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. For consistency with HDD and CDD, we used a baseline of 65 degrees F for both data points.

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

UCCS upgrades to LED lighting as part of any renovation or new construction projects.

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

N/A

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

N/A

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

Colorado Springs Utilities and the Energy Resource Center have conducted several energy audits. Based on these, retrofit projects are selected for each year depending on budget. UCCS has an Energy Star appliance policy. IT selects EPEAT Gold, Energy Star computers. Energy performance is included in capital renewal projects as much as possible.

Data source(s) and notes about the submission:

See the attached spreadsheet.

UCCS used 2021 data for onsite renewable energy generation. They plan to install meters on our solar arrays to better account for this energy generation.

UCCS adjusted the gross floor area of building space to remove unconditioned space, including parking garages and athletic fields.
