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

	Start Date	End Date
Performance Period	July 1, 2018	June 30, 2019
Baseline Period	July 1, 2014	June 30, 2015

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:

Fiscal Year 2014-15 is used as KSC's base year for WATER DATA because this was the year KSC's for it's previous completed GHG inventory submission.

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

KSC plumbing operations have been on the forefront of water saving and efficiency for over five years. KSC is aggressive in installing water-saving fixtures all across campus, from Residential Halls to Education buildings.
In addition, KSC made bold improvements to the underground condensate piping in our steam loop during 2018-19, when plumbing operations replaced sections of condensate return system with steam-rated hose. The use of steam hose lowers the cost of cast iron installation and does not require additional underground insulation. The results were immediately realized with an increase of condensate return temperature at the steam plant. The fuel savings became clear when comparing usage to previous years. Further savings were realized with reduced water and chemical costs of condensate at the plant. Overall this project proved to far more than a pipe replacement project and emerged as an thermal efficiency project with savings that will be realized for years.

Data source(s) and notes about the submission:

All 65 of KSC water meters are tracked for billing by the City of Keene. The City issues its bills on a quarterly basis, when Diana Duffy tracks usage and fees for all meters. KSC is confident about reporting its water usage for baseline AND performance years.
