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	695,176 MMBtu
Imported steam, hot water, and/or chilled water	7,948 MMBtu

Total site energy consumption, baseline year:

1,320,330.82 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:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	1.47 MMBtu per square meter	2.19 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:

10.05

Optional Fields

Documentation to support the performance year energy consumption figures reported above:

---

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

---

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).

See: https://www.mcgill.ca/buildings/design-standards

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.

The upcoming Energy Management Plan for 2021-2025 will include geo-exchange projects to be installed where feasible at the downtown campus.

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 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.

Note that the gross floor area of building space reported here (813,746) is different from that reported in PRE-4 because the performance year in this credit is 2018 rather than 2019.
