Level of ”Physical Risk Quantity” for the institution’s main campus as indicated by the World Resources Institute Aqueduct Water Risk Atlas:

Low

Part 1. Reduction in potable water use per person

Total water withdrawal (potable and non-potable combined):

	Performance Year	Baseline Year
Total water withdrawal	28,420,157.70 Gallons	35,769,160 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	28,420,157.70 Gallons	35,769,160 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Period	Jan. 1, 2020	Dec. 31, 2020
Baseline Period	Jan. 1, 2019	Dec. 31, 2019

If end date of the baseline year/period is 2004 or earlier, provide:

A brief description of when and why the water use baseline was adopted:

Since 2020, some pavilions no longer use potable water to cool the heat exchangers in the cooling towers for space conditioning. The ÉTS decided to purchase cooled water from the ÉCCU thermal power plant. This has the advantage of avoiding the use of chemicals for water treatment, the total elimination of water purges into the sewers and most importantly the elimination of risks of contamination of respiratory tract by Legionella bacteria.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	650	1,100
Number of employees resident on-site	0	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	8,075	7,929
Full-time equivalent of employees	945	945
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	6,927.50	6,930.50

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	4,102.51 Gallons	5,161.12 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:

20.51

Part 2. Reduction in potable water use per unit of floor area

Gross floor area of building space:
