Performance Year Baseline Year
Total water use 582,045,000 Gallons 635,507,000 Gallons

Potable water use:
Performance Year Baseline Year
Potable water use 582,045,000 Gallons 635,507,000 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2015 June 30, 2016
Baseline Year July 1, 2009 June 30, 2010

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

2009 is used as a consistent baseline across all credits and metrics, and coincides with the year that the IU Office of Sustainability was institutionalized.


Figures needed to determine "Weighted Campus Users":
Performance Year Baseline Year
Number of students resident on-site 10,413 12,335
Number of employees resident on-site 250 23
Number of other individuals resident on-site and/or staffed hospital beds 0 0
Total full-time equivalent student enrollment 37,750 37,443
Full-time equivalent of employees (staff + faculty) 8,619 8,155
Full-time equivalent of students enrolled exclusively in distance education 3,564 675.73
Weighted campus users 34,769.50 36,781.20

Potable water use per weighted campus user:
Performance Year Baseline Year
Potable water use per weighted campus user 16,740.10 Gallons 17,278.04 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:
3.11

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area 17,232,144 Gross Square Feet 15,889,707 Gross Square Feet

Potable water use per unit of floor area:
Performance Year Baseline Year
Potable water use per unit of floor area 33.78 Gallons / GSF 39.99 Gallons / GSF

Percentage reduction in potable water use per unit of floor area from baseline:
15.55

Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Yes

Area of vegetated grounds:
Performance Year Baseline Year
Vegetated grounds 1,000 Acres 900 Acres

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

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
---

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

The Global and International Studies Building (GISB), opened in 2015, has a 40,000 gallon capacity cistern which collects water from the majority of the rooftop area.

Many parts of campus do not have installed irrigation systems.

Water trucks that are used to spot water new plantings (initially grown in the campus nursery, then transplanted) utilize non-potable water for irrigation.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

Replacement of fixtures occurs during planned renovations. At that time, high-performance low-flow fixtures are used and are standard IU practice.
