1 and 2 emphasized reduced water use in landscaping and the building; Step 3 reclaimed water use; Step 4 captured and stored graywater; Step 5 captured and stored rainwater; and Step 6 focused on water use offsets. Although Steps 4 through 6 could not be implemented, the building has metered savings of 2 million gallons of water annually and achieves a 95% reduction in fixture potable water use (calculated in comparison to the Energy Policy Act of 2005). The water use savings due to energy efficiency benefits (embodied water in energy) is up to six times more than the water use savings from building fixtures. Partly as an extension of the work at Y2E2 and the SEQ2,
Stanford has invested in a reclaimed water system to serve more than 2 million square feet of development and reclaim approximately 60,000 gallons of water per day for non-potable use. Metered water use shows

that Y2E2 consumes one-sixth of the water of a similar laboratory building on campus.
