• Credit Info

Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):

	Performance Year	Baseline Year
Total water use	---	67,017,046 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	43,017,480 Gallons	46,981,880 Gallons

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

	Start Date	End Date
Performance Year	Jan. 1, 2018	Dec. 31, 2018
Baseline Year	Jan. 1, 2009	Dec. 31, 2009

A brief description of when and why the water use baseline was adopted:
Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	2,101	2,284
Number of employees resident on-site	12	10
Number of other individuals resident on-site and/or staffed hospital beds	20	0
Total full-time equivalent student enrollment	4,019	3,983
Full-time equivalent of employees (staff + faculty)	749	816
Full-time equivalent of students enrolled exclusively in distance education	6.60	0
Weighted campus users	4,119.30	4,172.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	10,442.91 Gallons	11,259.21 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	2,210,347 Gross Square Feet	2,263,247 Gross Square Feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	19.46 Gallons / GSF	20.76 Gallons / GSF

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