Level of ”Physical Risk Quantity” for the institution’s main campus as indicated by the World Resources Institute Aqueduct Water Risk Atlas:

Low

Part 1. Reduction in potable water use per person

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

	Performance Year	Baseline Year
Total water withdrawal	36,828,360 Gallons	42,620,305 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	36,828,360 Gallons	42,620,305 Gallons

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

	Start Date	End Date
Performance Period	Jan. 1, 2018	Dec. 31, 2018
Baseline Period	Jan. 1, 2007	Dec. 31, 2009

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:

Baseline is the average of years of 2008/2009/2010, prior to install of new Water Treatment Plant on campus (constructed from Jan 2010 to Jan 2011). Performance year 2018 has the most recent complete & accurate water consumption records.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	1,325.50	1,410
Number of employees resident on-site	30	30
Number of other individuals resident on-site	40	40
Total full-time equivalent student enrollment	1,959.80	2,013
Full-time equivalent of employees	963	710
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	2,570.98	2,442.25

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	14,324.67 Gallons	17,451.25 Gallons

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

17.92

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	1,261,380 Gross square feet	1,167,443 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	29.20 Gallons per square foot	36.51 Gallons per square foot

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

20.02

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

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	894 Acres	517 Acres

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water withdrawal per unit of vegetated grounds	41,195.03 Gallons per acre	82,437.73 Gallons per acre

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

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

---

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

---

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

When application allows, low- or no-flow fixtures and equipment are used.

In 2020, the Athletic Center updated the shower fixtures to low flow.

In 2011, Bard completed install of new water treatment facility, boosting water/energy efficiency significantly reducing is water consumption (in particular, reduced water needed for cleaning and back-washing of facility.
-In 2013, all urinals were replaced with waterless urinals.

Data source(s) and notes about the submission:

With the purchase of Montgomery Place in 2016, the campus grew from 550 acres to 930 acres. Because the Bard campus is rural and majority nature woods or fields, little to no water is used on these lands.

"Vegetated grounds" for performance and baseline was calculated using the following assumption:

Vegetated area = [Total campus acreage] - [total building acreage * 125%]

Multiplying by total building ft2 (i.e. all floors, not just the building footprint) is meant to account for parking lots, sidewalks, and roads, but it is only a rough estimate.
