None
A brief description of when and why the water use baseline was adopted:
We are using the year 2005 as a baseline in this credit because that is the earliest water data we have available.
None
Water recycled/reused on campus, performance year:
0
Gallons
None
Recycled/reused water withdrawn from off-campus sources, performance year:
0
Gallons
None
A brief description of any water recovery and reuse systems employed by the institution:
N/A
None
A brief description of any water metering and management systems employed by the institution:
In the few areas where our grounds are irrigated, the system is controlled by rain sensors. This sensor measures the amount of water that falls, and any difference between the rainfall and the needs of the landscaping are met by the irrigation system.
None
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
Throughout all of our updated buildings we use low-flow shower heads, toilets, and faucets.We are beginning a wholesale replacement of all showerheads to low flow models, and are creating a plan to address toilets and faucets.
None
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
All laundry machines on campus are Energy Star certified.
None
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
We use native and naturalized species in all campus plantings.
None
A brief description of any weather-informed irrigation technologies employed by the institution:
In the few places where our grounds are irrigated, the irrigation system is controlled by rain sensors.
None
A brief description of other water conservation and efficiency strategies employed by the institution:
Each new construction or commercial interiors project on campus pursues LEED certification. As part of the certification process, projects typically realize a 35% water reduction in comparison to UPC 2006 code compliant water fixtures and fittings. These same guidelines are applied to any projects that are smaller in scale and don't pursue LEED certification. As much as possible, water efficient fixtures and fittings are incorporated into any building modification project.
