A brief description of when and why the energy consumption baseline was adopted:
We used this baseline because it was the year prior to the energy savings performance contract for the campus. We also moved away from imported steam from Coors Corporation during this time period and started producing our own steam. We also continue to add buildings to campus.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.14 MMBtu per square foot | 0.23 MMBtu per square foot |
| Baseline year | 0.15 MMBtu per square foot | 0.27 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Colorado School of Mines has partnered with McKinstry to implement an energy awareness and savings program on campus called powerED. The three-year program launched in the Fall 2018 semester. McKinstry’s powerED program focuses on engagement, process, and performance. The “people” component educates building occupants about the importance of energy efficiency and resource conservation; the “process” component identifies and implements low- and no-cost operational and maintenance strategies to reduce energy use; and the “performance” component tracks, measures, analyzes and quantifies energy savings and carbon reduction. Those three components are used to increase staff and student awareness and engagement, identify energy savings opportunities, communicate performance results and promote success.
A brief description of energy use standards and controls employed by the institution:
In March 2012, as part of the an earlier Energy Savings Performance Contract, powerED contract, extensive lighting replacement and occupancy sensor installations, along with heat recovery on fume hoods and general exhaust in three largest lab buildings. In 2014, a second ESPC involved chiller replacement, additional lighting and occupancy sensors, and several smaller HVAC efficiency projects. The facilities team does have temperature recommendation ranges.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Mines is launching powerED as part of a larger building and operational improvement effort that began earlier this year. Most of the work focuses on energy efficiency retrofits and other campus improvement projects, including upgrading select lighting to LEDs in buildings and outdoor areas, adding dimming controls to a substantial number of classrooms to improve projector use, upgrading chilled water systems and improving system controls.

Data source(s) and notes about the submission:
NOTE ON IMPORTED ENERGY: The figures reported under "Imported steam, hot water, and/or chilled water" dropped from 134,013,381.0 MMBtu in the baseline year to zero in the performance year because the campus started producing its own steam in mid-2017. We renovated an old heating plant that came online in April 2017. Prior to that, we imported steam from Coors Brewery. After April 2017, we produced our own steam with 100% natural gas and no longer imported steam.
We used data from EnergyCap Software tracking for square footage and electrical. We subtracted the Mines Park common area electrical data because we are excluding this area outside the main campus because it is undergoing redevelopment and we won't have data on the new buildings in that area until after 2025.
