| Number of other individuals resident on-site | 0 | 0 |
| Total full-time equivalent student enrollment | 6,168 | 5,412 |
| Full-time equivalent of employees | 1,036 | 1,016 |
| Full-time equivalent of students enrolled exclusively in distance education | 7 | 0 |
| Weighted campus users | 5,866.75 | 5,269.75 |

| Gross floor area | 2,314,808 Gross square feet | 2,125,075 Gross square feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 37.13 Gallons per square foot | 33.96 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Area of vegetated grounds:

A brief description of the institution's water-related behavior change initiatives:
In 2018, Mines implemented a PowerED program that included education to students and staff about water conservation behavior (e.g., taking shorter showers, turning off water when brushing teeth, etc.)
A brief description of the institution's water recovery and reuse initiatives:
Due to water reuse restrictions put on large institutions by Colorado’s water laws and water appropriations to downstream states, Mines cannot legally engage in water recovery or reuse practices
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
In 2010, upgraded irrigation equipment with more efficient equipment. The facilities management department also did domestic water retrofits to make them more efficient. The energy reduction measures also reduce steam used for Hill Hall, which reduces water consumption.

Energy Cap Software and Grounds Management.
Why is water measured in gallons and not kilogallons? We don't measure electricity in watts but kilowatts.
We subtracted the water usage from Mines Park because it is located outside the main campus and is under redevelopment.
