Showerheada | 2.0 gpm and WaterSense labeled |
Lavatory faucet and bar sink-private | 1.5 gpm and WaterSense labeled |
Lavatory faucet-public (metered) | 0.25 gpcb |
Lavatory faucet-public (nonmetered) | 0.5 gpm |
Kitchen faucet-private | 2.2 gpm |
Kitchen and bar sink faucets in other than dwelling units and guestrooms | 2.2 gpm |
Urinal | 0.5 gpf and WaterSense labeled or nonwater urinal |
Water closet-public and remotec | 1.6 gpf |
Water closet-public and nonremote | 1.28 gpf averaged, e |
Water closet-tank type, private | 1.28 gpf and WaterSense labeledd |
Water closet-flushometer type, private | 1.28 gpfe |
Prerinse spray valves | 1.3 gpm |
Drinking fountains (manual) | 0.7 gpm |
Drinking fountains (metered) | 0.25 gpcb |
For SI: 1 foot = 304.8 mm, 1 gallon per cycle (gpc) = 3.8 Lpc, 1 gallon per flush (gpf) = 3.8 Lpf, 1 gallon per minute (gpm) = 3.8 Lpm. |
a. Includes hand showers, body sprays, rainfall panels and jets. Showerheads shall be supplied by automatic compensating valves that comply with ASSE 1016 or ASME A112.18.1/CSA B125.1 and that are specifically designed to function at the flow rate of the showerheads being used. |
b. Gallons per cycle of water volume discharged from each activation of a metered faucet. |
c. A remote water closet is a water closet located not less than 30 feet upstream of other drain line connections or fixtures and is located where less than 1.5 drainage fixture units are upstream of the drain line connection. |
d. The effective flush volume for a dual-flush water closet is defined as the composite, average flush volume of two reduced flushes and one full flush. |
e. In public settings, the maximum water use of a dual flush water closet is based solely on its full flush operation; not an average of full and reduced volume flushes. |
Strike Section 702.6 of the International Green Construction Code in its entirety and substitute new Section 702.6 in the Green Construction Code in its place to read as follows:
Appliances. Sections 702.6.1 through 702.6.4 shall regulate appliances that are not related to space conditioning.
Clothes washers. Clothes washers of the type in the ENERGY STAR program as defined in "ENERGY STAR® Program Requirements, Product Specification for Clothes Washers, Eligibility Criteria," shall have a water factor (WF) not exceeding 6.0 and a modified energy factor (MEF) of not less than 2.0.
Ice makers. Ice makers producing cubed-type ice shall be ENERGY STAR qualified as commercial ice machines. Ice makers of a type not currently ENERGY STAR qualified, such as flake, nugget or continuous-type ice makers, shall not exceed the total water use of 25 gallons per 100 pounds (208 L per 100 kg) of ice produced.
Exception: Under counter ice makers.
Dishwashers. Dishwashers shall be ENERGY STAR qualified where an ENERGY STAR category exists for the specific dishwasher type. Where an ENERGY STAR category does not exist, the dishwasher shall be in accordance with Table 702.6.4.
TABLE 702.6.4
MAXIMUM WATER CONSUMPTION FOR COMMERCIAL DISHWASHERS
DISHWASHER TYPE | MAXIMUM WATER CONSUMPTION |
Rackless conveyor | 2.2 gallons per minute |
Utensil washer | 2.2 gallons per rack |
For SI: 1 gallon per minute = 3.785 Lpm.
