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

Low to Medium

Part 1

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

	Performance Year	Baseline Year
Total water use	96,432 Cubic meters	303,693 Cubic meters

Potable water use:

	Performance Year	Baseline Year
Potable water use	91,672 Cubic meters	303,693 Cubic meters

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

	Start Date	End Date
Performance Year	May 1, 2017	April 30, 2018
Baseline Year	June 1, 2004	May 31, 2005

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:

We are using the same baseline year as for the energy greenhouse gas emissions criteria. It corresponds to the year just before opening the new Lassonde buildings, which is are LEED Gold certified buildings. Since then, many efforts have been deployed to considerably decrease Polytechnique's water consumption.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	0	0
Number of employees resident on-site	0	0
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	6,806.80	4,006.83
Full-time equivalent of employees (staff + faculty)	1,529.36	1,433.57
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	6,252.12	4,080.30

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	91,672 Cubic meters	303,693 Cubic meters

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

80.30

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	120,233 Gross square meters	74,037 Gross square meters

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	18.71 Cubic meters per square meter	100.67 Cubic meters per square meter

Percentage reduction in potable water use per unit of floor area from baseline:

81.41

Part 3

Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):

Yes

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	0.50 Hectares	0.50 Hectares

Total water use (potable + non-potable) per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	20,618,473.38 Cubic meters per hectare	64,933,694.57 Cubic meters per hectare

Percentage reduction in total water use per unit of vegetated grounds from baseline:

68.25

Optional Fields

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

---

A brief description of the institution's water recovery and reuse initiatives:

---

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

In the last 15 years, water consumption at Polytechnique has been divided by 3. The main reason for this important decrease is the replacement of equipment by more efficient equipment (in terms of water consumption). New toilets have been installed, but some important changes also come from modifications in laboratory equipment or procedures, and from the installation of many new HVAC systems. When a change of equipment is needed, the efficiency in terms of water use is always considered.
