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	18,800,000 Kilowatt-hours	64,145.60 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	63,903.73 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

128,049.33 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

74,037 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	June 1, 2004	May 31, 2005

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

The new buildings (Pavillons Lassonde), which are LEED gold certified buildings, opened in the fall of 2005. We wanted to assess the benefits of having improved our campus with LEED certified buildings.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	1.17 MMBtu per square meter	1.88 MMBtu per square meter
Baseline year	1.73 MMBtu per square meter	2.60 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:

27.57

Data source(s) and notes about the submission:

For this section, we are using the flexibility offered by STARS to report older assessment and inventories due to the impact of COVID-19 pandemic. Data for year 2018-2019 have been chosen since this is the last complete year not affected by COVID-19; therefore it represents normal activities on campus. Furthermore, this choice is considered a conservative one since Polytechnique Montréal continuously improves its energy perfomances, so the years 2019-2020, 2020-2021 and 2021-2022 should show better energy performance than year 2018-2019.

The information presented here is self-reported. While AASHE staff review portions of all STARS reports and institutions are welcome to seek additional forms of review, the data in STARS reports are not verified by AASHE. If you believe any of this information is erroneous or inconsistent with credit criteria, please review the process for inquiring about the information reported by an institution or simply email your inquiry to stars@aashe.org.
