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

FY2013 was the baseline selected for our first STARS submission in March 2018. At the time we selected a baseline year 5 years prior to the performance year and used that across credits. We are continuing to use this baseline to maintain consistency across submissions.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	1,806	2,068
Number of employees resident on-site	14	20
Number of other individuals resident on-site	7	0
Total full-time equivalent student enrollment	1,926	2,068
Full-time equivalent of employees	633.70	737
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	2,381.78	2,625.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	44.82 Cubic meters	58.12 Cubic meters

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

22.88

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

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	130,780.67 Gross square meters	133,408.71 Gross square meters

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	0.82 Cubic meters per square meter	1.14 Cubic meters per square meter

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

28.64

Part 3. Reduction in total water withdrawal per unit of vegetated grounds

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	254.95 Hectares	254.95 Hectares

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water withdrawal per unit of vegetated grounds	418.73 Cubic meters per hectare	598.58 Cubic meters per hectare

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