The credit guidelines indicate that metering faucets are limited to .25 gallons per use. This is the typical use of a metered faucets less than that would typically not wash your hands, to be specific - does this mean that metered faucets- and by that I mean faucets operated by electronic eye for a single pre-set flow: are not a valid strategy for achieving this credit?

Metered faucets can be used on a project pursuing this credit, but the LEED baseline for faucets is so stringent it will be tough to contribute much to the credit threshold in this way. Using toilets, urinals, and showers to earn the credit will be more important, as well as possible water reuse.

See additional guideline information from USGBC - It seems the baseline .25 gal per cycle can apparently be reduced in design case to 0.1 if you use .5 gpm @ 12 second cycle (the average cycle time for autocontrol faucets). This was adequate on my project to reduce beyond the 40% reduction, thereby eliminating the need for a $90,000 rainwater harvesting system to achieve 11 points.
