Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 180,892,971 Kilowatt-hours 617,206.82 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 0 Kilowatt-hours 0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 695,040 MMBtu
Imported steam, hot water, and/or chilled water 7,948 MMBtu

Total site energy consumption, baseline year:
1,320,194.82 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
797,055 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period May 1, 2012 April 30, 2013

A brief description of when and why the energy consumption baseline was adopted:
In response to "The 2030 Energy Policy" released by the Québec provincial government in 2016, McGill created the "Energy Management Plan: 2016-2020 Implementation Phase." This plan aimed for a 22% reduction in energy use intensity below the provincial government-defined 2012-2013 baseline as well as a 64% reduction in building-related greenhouse gas emissions below the 1990 levels.

Source energy

Source-site ratio for imported electricity:
2

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 1.22 MMBtu per square meter 1.83 MMBtu per square meter
Baseline year 1.66 MMBtu per square meter 2.43 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
24.66

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Utilities and Energy Management unit:
Our focus is on performing infrastructure projects to promote energy efficiency across the campus by upgrading major HVAC and distribution systems. Renovation projects include installing occupancy sensors to automatically control lights and HVAC systems when unoccupied.
------------
Compared to other spaces on campus, labs consume vast amounts of materials and rely on energy-intensive equipment. McGill's new Sustainable Labs certification program includes criteria for reducing energy use in labs. The checklist requires applicants to take the following actions:

1. We turn off lights at the end of the day or we have motion sensitive lights installed
2. We have discussed and decided which pieces of equipment must be left on all the time, which should be turned off daily and which may be turned off until needed.
3. We turn off or unplug equipment when it is not in use or use outlet timers to turn off equipment automatically
4. We repair and maintain all equipment to ensure safety and efficiency
5. We ensure that the coils and the filters of our freezers and refrigerators are kept clean of dust buildup
6. We remove frost build up from our freezers regularly
7. We do a full defrost of our freezers at least once per year.
8. We maintain a record or inventory of samples and reagents in our fridges and freezers.
9. We close fume hood sashes when we are not actively working in the fume hood.
10. We have placed prompts to remind users to close the fume hood.
11. We don’t work in the fume hood with the sash pulled all the way up.
12. We don’t use the fume hood to evaporate chemicals or reagents. We dispose of them in a waste container instead.

A brief description of energy use standards and controls employed by the institution:
The university adheres to construction standards that mandate certain efficiency measures be incorporated within designs for new construction and major renovation projects. This is particularly important in promoting energy efficiency within projects where energy efficiency is not the primary reason for the work to be performed (gut renovations, deferred maintenance, etc.).

The standards cover energy efficiency requirements for lighting, HVAC, insulation, MEP, and commissioning. There are also specific standards requiring energy models to be performed and mandate designs to be 20% better than energy code ASHRAE 90.1-2010 (Appendix G).

Additionally the University must follow provincial regulations which mandate all new construction and major renovation projects to use mostly renewable energy (80%+ renewable, depending on project). This is typically achieved with electric heating systems that utilize Hydro-Québec's low carbon electricity (which comes from large Hydro plants).

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
McGill University construction standards require the use of LEDs in all new construction and major renovation projects. 85% of parking garages have been retroffited with LEDs.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The university has one geo-exchange (ground-source) loop currently installed and serves a small building. A hybrid passive solar project is currently in construction. Two smart energy grids projects were implemented in 2021.

A brief description of co-generation employed by the institution:
None. McGill doesn't have cogeneration on campus for two reasons:
- Québec's electricity is 99% from renewable sources, therefore, generating electricity on campus would increase our GHGs.
- Québec's electricity rates are very competitive and deploying a cogeneration system doesn't offer a viable payback with the current rate structure.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
As part of McGill's Energy Management Plan, many major HVAC systems have been upgraded or an in the process of being upgraded. Many of the on-going projects involve integration of heat-recovery systems to recover energy that would be otherwise wasted. Other upcoming strategies include electrification of heating systems to reduce fossil fuel consumption across campus.

Data source(s) and notes about the submission:
RE: Source-site ratio for imported electricity: 2.0 as per STARS Credit Info for Canada, although the case should be made that Québec's electric profile is almost completely from hydro-electric stations and is significantly different from Canada's overall grid profile.
