Strike Table 702.1 of the International Green Construction Code in its entirety and insert new Table 702.1 in the Green Construction Code in its place to read as follows:

TABLE 702.1

MAXIMUM FIXTURE AND FITTING FLOW RATES
FOR REDUCED WATER CONSUMPTION

FIXTURE OR FIXTURE FITTING TYPE	MAXIMUM FLOW RATE
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:

 

702.6 Appliances.  Sections 702.6.1 through 702.6.4 shall regulate appliances that are not related to space conditioning.

 

702.6.1 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.

 

702.6.2 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.

 

702.6.3 Steam cookers.  Steam cookers with drain connections shall consume no more than 5 gal (18.9 L)/hour/pan, and those without drain connections shall consume no more than 2 gal (7.6 L)/hour/pan.

 

702.6.4 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.

Strike Section 702.7 of the International Green Construction Code in its entirety without substitution.

 

Strike Section 702.9 of the International Green Construction Code in its entirety without substitution.

Strike Section 702.11 of the International Green Construction Code in its entirety without substitution.

Strike Section 702.13 of the International Green Construction Code in its entirety and insert new Section 702.13 in the Green Construction Code in its place to read as follows:

702.13 Automated vehicle wash facilities.  Not less than 50 percent of the water used for the rinsing phase of the wash cycle at automated vehicle wash facilities shall be collected to be reused for the washing phase.  Towel and chamois washing machines shall have high-level water cut-offs.

 

702.13.1 Nonpotable water use.  Except for water recirculated within the facility, potable and nonpotable water use for automobile washing shall not exceed 40 gallons (151 L) per vehicle for in-bay automatic washing, and 35 gallons (132.5 L) per vehicle for conveyor and express type car washing.

 

Exception:  Bus and large commercial vehicle washing facilities.

 

Strike Section 702.17 of the International Green Construction Code in its entirety without substitution.
