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 | 18,131,625 Kilowatt-hours | 61,865.10 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 | 125,193.12 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Environmental sustainability is part of the college mission, core values, and strategic initiatives. Campus sustainability council works to increase communication about achieving high performance building standards on new projects.
A brief description of energy use standards and controls employed by the institution:
Colorado College employs the following temperature standards:
-During heating season occupied hours, the target building temperature is 71 degrees for academic, administrative and residential areas.
-During heating season unoccupied hours, the target building temperature is 65 degrees for academic, administrative and residential areas.
-During cooling season occupied hours, the target building temperature is 76 degrees for academic, administrative and residential areas.
-During evenings, weekends and holidays, the temperature will default to unoccupied settings. Holidays include Thanksgiving & Winter Breaks.
-Research facilities and labs requiring specific setpoints are exempt from this policy and will be managed on a case by case basis by Facilities Services. Exemption requests can be submitted via the Work Order Request form online.
-Spaces scheduled for special events through the campus reservation system will be programmed as occupied.
-Standard occupied hours for academic and administrative spaces are 6 a.m. to 6 p.m.
-Standard occupied hours for residential areas are continuous, except during holidays.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Colorado College has installed both interior and exterior LED lighting technology in many areas across campus, which include the following: the walkway lighting for Packard Hall, the walkway lighting for the Tiger Trail steps to Stewart Field, the walkway pole lighting for Cutler walkway to Cascade, the walkway pole lighting at the intersection south of Tutt Library, the exterior door lighting north side of Cossitt Hall, and the interior main hallway lighting Cossitt Hallway. The entire interior and exterior of the Spencer Center, which was undergoing renovations until August of 2014, is now lit by LED's. CC has newly installed LED lights in the Honnen Ice Arena, Schlessman Pool, Cossitt rooms, the El Pomar auxillary gyms, the El Pomar racquetball courts, and in many of the exterior walkway lights around campus.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
CC does employs passive solar heating with its solar thermal array on the roof of the Worner Student Center.
CC has a geothermal heating system under Armstrong Quad.
CC has a geothermal heating system under Armstrong Quad.
A brief description of co-generation employed by the institution:
CC has a co-gen turbine in the Tutt Libarary space. However, the unit has not been in operation during the past two years due to software upgrades, fuel volume requirements, and the fact that CC now receives 100% of its electricity from local solar, making the operation of the unit less attractive for our greenhouse gas emissions.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The college employs an Campus Energy Manager who holds a professional engineer license and who is certified through the Association of Energy Engineers as a Certified Building Commissioning Professional. The Campus Energy Manager performs ongoing building recommissioning throughout the campus. He also performs commissioning on the new and renovation projects.
