What flush rate as the baseline water consumption for water closets if the Energy Policy Act establishes?

1.6 gallons per flush

EPAct 1992 establishes water consumption for fixtures used to calculate the baseline case Flush fixtures are rated in Gallons Per Flush (gpf) and includes water closets and urinals Flow fixtures are rated in Gallons Per Minute (gpm) and includes lavatories, sinks, showerheads and prerinse spray valves Per EPAct: water closets = 1.6 gpf; urinals = 1.0 gpf; lavatories = 2.2 gpm; faucets = 2.2 gpm; showerheads = 2.5 gpm; The baseline case is calculated using the number of occupants and the EPAct 1992 flush and flow rates of the fixtures; the design case is calculated using the number of occupants and the flush/flow rates for water efficient fixtures such as WaterSense, HET, waterless urinals, dual flush water closets, etc.; subtract the design case from the baseline case for amount of water savings
