Performance Year Baseline Year
Total water use --- 584,137,587 Gallons

Potable water use:
Performance Year Baseline Year

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, 2008 June 30, 2009

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

For consistency's sake we have adopted a 2009 baseline across the board for all STARS operational credits, as that is the earliest year for which we have strong consistent data sets across categories.

Figures needed to determine "Weighted Campus Users":

Number of employees resident on-site 0 0
Number of other individuals resident on-site and/or staffed hospital beds 0 0
Total full-time equivalent student enrollment 28,922 26,055
Full-time equivalent of employees (staff + faculty) 8,552 7,403
Full-time equivalent of students enrolled exclusively in distance education 2,427

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:

The University of Cincinnati (UC) takes the conservation of water seriously throughout the daily operation of its buildings—as evidenced by UC’s commitment to building all its new buildings or large- scale renovations to LEED standards. In existing buildings, facility staff are given comprehensive training on detecting and fixing water leaks as soon as discovered. From a purchasing perspective, it is the policy of UC facilities to install high efficiency water fixtures, where appropriate water saving technologies exist. UC’s water conservation policies also extend to the proper maintenance of the utility plant’s chilled water and steam distribution and return systems. These utility systems utilize a vast amount of water and the proper return and reuse of this water represents an enormous ongoing savings for the campus. These building-centered water management strategies parallels additional efforts on the campus to manage storm water runoff and minimize harmful impacts to the larger Cincinnati sewer system.

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

In order to reduce runoff of storm water from roof surfaces, UC has started installation of green roofs. A green roof is a roof surface covered with vegetation in a growing medium. The Zimmer Roof Garden functions as a green roof. As part of the renovation of Procter Hall, a partial green roof was constructed in Spring 2012. Another green roof is installed on DAA as of 2013. In addition to retaining stormwater, green roofs help insulate buildings, create a habitat for urban wildlife, and help mitigate the heat island effect.

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):

UC also promotes the conservation of water and has installed low-flow toilets and other fixtures wherever possible. The Campus Conservation Nationals competition encourage residence hall students to compete each year to see which hall can conserve the most water.
