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	245,794 Cubic meters	229,419 Cubic meters

Potable water use:

	Performance Year	Baseline Year
Potable water use	245,794 Cubic meters	229,419 Cubic meters

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

	Start Date	End Date
Performance Year	Jan. 1, 2017	Dec. 31, 2017
Baseline Year	Jan. 1, 2015	Dec. 31, 2015

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:

The water baseline was adopted for this STARS report. 2015 was selected at the baseline year as we have recent complete data for that year and we can see the change that has happening recently.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	3,857	1,933
Number of employees resident on-site	12	0
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	16,373	14,767
Full-time equivalent of employees (staff + faculty)	1,970.82	1,986
Full-time equivalent of students enrolled exclusively in distance education	961	740
Weighted campus users	14,004.37	12,493

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	4,636.55 Cubic meters	4,851.20 Cubic meters

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

4.42

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	380,382.37 Gross square meters	212,981.89 Gross square meters

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	15.86 Cubic meters per square meter	26.44 Cubic meters per square meter

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

40.01

Part 3

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

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	4.05 Hectares	6.07 Hectares

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

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	6,493,190.53 Cubic meters per hectare	4,040,405.87 Cubic meters per hectare

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

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:

Water Filling Stations: When new students arrive at Laurier’s Waterloo and Brantford campuses in September, refillable water bottles are included in their welcome package. The goal is to discourage students from quenching their thirst with water in one-time-use plastic bottles. Bottled water can no longer be purchased in vending machines or at food outlets at Laurier campuses in both Brantford and Waterloo. Instead, students are encouraged to bring their reusable bottles to 22 water fill-up stations, set up in high-traffic areas of the campuses. These new models feature a digital counter which tracks the number of plastic water bottles each fountain has helped to avoid.

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

In our newly constructed LEED Gold building, Lazaridis Hall, a grey water system collects and filters rainwater for use in toilets and landscaping. Laurier uses a 37,000 litre rain water harvesting system to water plant material on campus and has also recently installed a 2350 litre system that is also used for irrigation.

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):

Also included in the LEEP Phase 1 & 2 projects was a retrofit of water fixtures in 32 buildings. The buildings are a mix of residential, administration, academic, athletic, and dining each with a large demand for water. Tank and flush valve toilets were replaced with 3.0 and 4.2 liter low flow type in all locations where 6.0 liter or greater were existing. Aerators and shower heads were also installed in all locations.
