Low

Part 1

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

	Performance Year	Baseline Year
Total water use	---	505,073,616 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	467,801,000 Gallons	505,073,616 Gallons

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

	Start Date	End Date
Performance Year	Jan. 1, 2016	Dec. 31, 2016
Baseline Year	Jan. 1, 2014	Dec. 31, 2014

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:

There was a significant increase in water use in the 2014 baseline year used. This year was chosen to demonstrate the progress made by Virginia Tech in the two year time period to reduce the campus-wide water use and wastewater production.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	9,433	9,025
Number of employees resident on-site	2	2
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	33,223	31,911
Full-time equivalent of employees (staff + faculty)	7,678	7,602
Full-time equivalent of students enrolled exclusively in distance education	1,010	909
Weighted campus users	32,277	31,209.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	14,493.32 Gallons	16,183.20 Gallons

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

10.44

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	10,140,464 Gross square feet	9,989,360 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	46.13 Gallons per square foot	50.56 Gallons per square foot

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

8.76

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	---	---

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

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	---	---

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