Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 123,097 MMBtu | 141,580 MMBtu |
| Electricity from on-site renewables | 1,038 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) | 61,817 MMBtu | 87,282 MMBtu |
| Total | 185,952 MMBtu | 228,862 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | Jan. 1, 2017 | June 30, 2018 |
| Baseline Year | Jan. 1, 2014 | Dec. 31, 2015 |
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):
2019: It does not look like natural gas consumption was a part of the baseline or subsequent years (prior to 2019). Therefore, baseline was changed to 2014, which was the first year recorded data was made available-- to add to this report for energy consumption metrics.
2014-2015: The baseline was selected because that was the first year CNM collected data to begin their sustainability benchmarks.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 1,830,991 Gross square feet | 1,732,047 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 | 0.10 MMBtu per square foot | 0.13 MMBtu per square foot |
| Source energy | 0.25 MMBtu per square foot | 0.31 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 | 4,169 Degree-Days (°F) |
| Cooling degree days | 1,559 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 294,592 Square feet |
| Healthcare space | 798 Square feet |
| 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:

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):
2019: Many news blurbs go out about what energy conservation measures have been implemented, including computer shutdown programming, retro-commissioning projects, and energy setpoint standards (see below for link).
Due to the changing culture regarding energy use, we have implemented a ground source heat pump system for one of our largest energy consuming buildings (Smith Brasher), which now uses ZERO natural gas.
We also have a 1.3 MW solar facility that is under contract to be built at WS Campus during Fall and Spring semesters (2019-2020).
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
2019 Update:
In 2017, the institutions first energy standards and guidelines were also published https://www.cnm.edu/depts/hr/current-employees/policies-and-procedures/the-source/is-1420.
2014: CNM tries to maintain temperatures within the building at 68 degrees and have all building set at that point (Luis Campos, 2014).
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
In all newly constructed and renovated buildings, LED lights are placed in all hallways and other generally lit areas.Additionally, CNM has entered into recommissioning projects with the local electric utility (PNM) and has replaced many of the older bulbs with LEDs as a part of the program efforts. CNM has won several awards through the utility for these programs.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
2019 Update: We have implemented a ground source heat pump system for one of our largest energy consuming buildings (Smith Brasher), which now uses ZERO natural gas. This brought our gas consumption way down, but for some reason gas was not reported previous years.
We also have a 1.3 MW solar facility that is under contract to be built at WS Campus during Fall and Spring semesters (2019-2020).
2014: Three Buildings; WSI, Rio Rancho and Ken Chappy have solar panels that supplement electricity.
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):
2019 Update: CNM Energy Guidelines require all appliances to be at minimum of Energy Star Certified. Additionally, CNM IT Department requires all computers and other equipment to meet minimum Energy Star 5.0.
There have been several retro-commissioning programs implemented that have replaced HVAC equipment, such as bolers.
2014: CNM has on call commissioning services to assist in retro-commissioning. CNM is pending the completion of the buidling managment system before retrocommisioning and has identified three buildings that will be retrocommisioned.

Data source(s) and notes about the submission:
2019 Update:It was discovered there was not any natural gas data entered in the STARS report for original baseline year 2008. Therefore,the baseline year was changed to 2014 since that was the first year that complete data was available.
