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

UM has consistently been recording and monitoring its energy consumption since 2011 when we hired an energy manager to work alongside our other facilities engineers and track all of our building performance and utilities. The position has been found to pay for itself beyond what we anticipated and our emissions footprint has been reduced as a bonus. There is no specific document or policy that inspired this tracking and record-keeping, but tracking our natural gas and electricity consumption is standard practice now.


Source-site ratio for imported electricity:
3.14

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.10 MMBtu / GSF 0.17 MMBtu / GSF
Baseline year 0.14 MMBtu / GSF 0.23 MMBtu / GSF

Percentage reduction in total source energy consumption per unit of floor area from baseline:
27.09

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

The most impactful strategy that has positively impacted our energy use on campus is the State of Montana-wide policy mandating LEED Silver certification for any new construction or major renovation over $3M. This has meant that all of our construction has been designed and built to a higher standard than in prior years. We also have worked hard over the last 7-8 years to invest more funds each year into energy conservation. Rather than being a campus-wide energy and behavior change campaign, this has been the effort of several budget managers and facilities engineers in the facilities services department.

We have also used our Green Office Program participants to act as energy conservation ambassadors in their areas, though the impacts of their influence are not quantifiable at this time.


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

Ambient building temperatures are modulated by a programmable computer system which is set to reduce heating temperatures and raise cooling temperatures during unoccupied hours. UM facilities regularly installs occupancy and vacancy sensors around campus as funding permits.


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

LED upgrades have happened piecemeal around campus over the last 7 years. Updating lighting has been at the top of the priority list as rooms, labs, and entire buildings have been renovated. In 2021, 3 buildings are scheduled to receive lighting upgrades.


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

Several of our newer buildings utilize ground source heating and cooling systems, including the Davidson Honors College and the Payne Native American Center. More of these geothermal systems continue to be added across campus to save energy and reduce heating and cooling costs to the institution.
UM currently has small-scale rooftop solar on the Todd Building, Fitness & Recreation Center, the Lommasson Building, and Eck Hall. We are working on adding solar to the Mansfield Library roof next year (2022).


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

The co-generation system was implemented in 2005 and is composed of a 440kW steam powered turbine, which runs off waste steam from a natural gas fired boiler system. In fall 2020, UM Facilities Services enlisted the help of McKinstry to design a 2-turbine CHP that will come online in fall 2022.
