A brief description of when and why the energy consumption baseline was adopted:
FY1990/91 was selected as the baseline year to conform with Kyoto Protocol reporting. UM has focused on energy efficiency since 1977 when it hired its first energy engineer and installed its first building automation system.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.16 MMBtu per square foot | 0.21 MMBtu per square foot |
| Baseline year | 0.24 MMBtu per square foot | 0.31 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:
The Climate Action Plan and Sustainable Building Guidelines formalize and entrench the UM commitment to sustainability and energy efficiency.
A brief description of energy use standards and controls employed by the institution:
Sustainable Building Guidelines were created with assistance from Sustainable Solutions Group (SSG) and submitted for the Board of Governor's endorsement in Spring 2022. These guidelines facilitate the consistent application of sustainability considerations across all construction projects. The guidelines include documents, templates, and checklists outlining best practices, technologies, and methods for creating and maintaining more sustainable buildings and renovations on campus. These guidelines will also help the University of Manitoba reach its emission reduction goal of 50% lower by 2030 and net-zero by 2050, as set out in the UM Climate Action Plan. The guidelines consider:
- Parameters for all new construction projects, major renovations, and major landscape projects
- Material choice, including life-cycle carbon accounting (both operating and embedded) and/or carbon-based building codes
- Monitoring-based commissioning for evaluating seasonal and long-term building performance, as well as preventative maintenance requirements through the UM Integrated Work Management System
- Ongoing monitoring including Energy Use Intensity (EUI), Thermal Energy Demand Intensity (TEDI), absolute energy reductions, greenhouse gas emissions intensity, potable water use intensity, indoor air quality, and weight of construction waste diverted
- Involvement of key university stakeholders for ongoing development of the guidelines
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting is standard in all new facilities. LED retrofits in existing facilities are incorporated into renovations. Retrofit of large areas with considerable lighting loads are evaluated on a case-by-case basis. Recent large-area LED upgrades to include the Max Bell Centre ice rink and fieldhouse, the Investors Group Athletic Centre gymnasia, and the Education II main corridor.
Occupancy sensors are included in renovations and new facilities to automatically turn lights on and off.
Lighting controllers that provide multiple lighting scenarios to accommodate different room uses are now standard equipment for classroom and meeting room renovations
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
District heat recovery repurposes the existing campus-wide chilled water piping network during the heating season to collect, store, and re-distribute waste heat around the Fort Garry Campus. Up to 20 MMBtu/hr of waste heat is collected from areas with too much heat and re-distributed to areas that require heat. This recovered heat provides preheating for most of the incoming make-up air for UM laboratory facilities.
A brief description of co-generation employed by the institution:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The Climate Action Plan (CAP) and Sustainable Building Guidelines formalize and entrench the UM commitment to sustainability and energy efficiency The CAP charts a course to help UM halve its GHG emissions by 2030 and to become carbon neutral by 2050.
Efforts focus on eliminating waste and improving efficiency while maintaining or improving occupant comfort.
Recent energy efficiency efforts leveraged HVAC upgrades with Demand Control Ventilation (DCV) controls to help eliminate over-ventilation of unoccupied spaces. CO2 monitoring within classrooms and meeting rooms automatically and immediately enables room ventilation upon detecting occupancy. Funding request initiatives that began in 2019/20 are finally beginning to show results. There are two once-in-in-a-lifetime initiatives that are approved and in design:
•Fort Garry District Energy Upgrades ($36.1M) will replace aging and inefficient district heating and cooling infrastructure with new energy-efficient and resilient equipment:
o Boiler Replacement - Install a new condensing natural gas-fired boiler
o Boiler Heat Recovery - Upgrade the heat recovery systems on Boilers 7 and 8 from non-condensing to condensing
o New Electric Boiler - Install the first electric boiler
o Chiller Replacement - Replace the oldest chiller
o Deaerator & Feedwater Tanks Replacement - Replace with an integrated unit
• Fort Garry Campus Electrical Re-Servicing ($82M) will replace the failing University Station, constructed over 60 years ago in 1960, with four new smaller satellite substations, each serving one-quarter of the campus. Re-servicing will support additional electrification initiatives including more charging stations for electric vehicles, the first electric boilers for district heating, and a new electric chiller for district cooling. The new design will satisfy all code requirements and accommodate future expansion for the next 50 years. Work is proceeding to prepare detailed designs of the overall system and the four satellite substations
