• 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	---	29,364,000 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	16,125,000 Gallons	29,364,000 Gallons

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

	Start Date	End Date
Performance Year	Jan. 1, 2014	Dec. 31, 2014
Baseline Year	Jan. 1, 2005	Dec. 31, 2005

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	448	400
Number of employees resident on-site	12	2
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	2,134	1,136
Full-time equivalent of employees (staff + faculty)	406	406
Full-time equivalent of students enrolled exclusively in distance education	135	0
Weighted campus users	1,918.75	1,257

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	8,403.91 Gallons	23,360.38 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	1,100,000 Gross square feet	984,000 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	14.66 Gallons per square foot	29.84 Gallons per square foot

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

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	420 Acres	32 Acres

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

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	0 Gallons per acre	917,625 Gallons per acre

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