The maximum reductions achievable by water conservation can be assessed using a bottom-up approach to estimate water needs by end-use across campus and the available best practices.  This can form the basis for both refined water conservation targets and updated facilities standards for new construction, renovations, or retrofits of all buildings, facilities, and auxiliaries.  Campus facilities standards could be updated to reflect the intent to reduce the water use for campus buildings.  These standards could define a maximum amount of water use per weighted user and per building area.  In addition, they could provide requirements that restrict or exclude landscape irrigation with potable water.  These standards would apply to all new construction and renovations on our campus, including auxiliaries.  The related facilities standards could be reviewed and updated every five years to incorporate technological advances.
