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

The 2005 water baseline was adopted based on its relation to the energy performance contracts completed by Siemens. The baseline is before the energy contracts were implemented.

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:

In fiscal year 2016, George Mason University piloted a energy and water reduction campaign within Housing and Residence Life that included reminder prompts to turn off lights, set thermostats, and take shorter showers


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

Water recovery and reuse systems are limited due to concerns of local governing
authorities in certain locations and situations. George Mason University's Child Development Center Garden has an irrigation system from Water Management, Inc. The irrigation system utilizes rainwater to water the garden.


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):

Since 2005, Mason has initiated two energy savings performance contracts where heating, ventilation, and air conditioning equipment were upgraded along with lighting and water fixtures. Mason also follows Virginia state policy which states that all new buildings should be built to LEED Silver or equivalent. George Mason University's Design Information Manual also prioritizes water saving infrastructure when constructing new buildings.
