Notes:

Reference: LEED 2009 for New Construction and Major Renovations Rating System
All Water Efficiency credits measure water savings by comparing a baseline case against the proposed design case. The baseline case uses the flow and fixture rates from the EPAct 1992 standard.

The baseline water usage is based on estimated occupant usage (Full Time Equivalent calculations) and the water fixtures and fittings, such as:

Commercial toilets have a baseline water use of 1.6 gallons per flush
Commercial urinals have a baseline water use of 1.0 gallons per flush
Commercial lavatory faucets have a baseline water use of 2.2 gallons per minute

Residential toilets have a baseline water use of 1.6 gallons per flush
Residential lavatory faucets have a baseline water use of 2.2 gallons per minute
Residential kitchen faucets have a baseline water use of 2.2 gallons per minute
Residential showerheads have a baseline water use of 2.5 gallons per minute
