Does the flow rate to be specified in the online template for all the kitchen/public and private lavatory faucets/showerheads to be at a specific PSI? For. eg. the showerhead used in the building works at say 40 PSI with a flow rate of 2 GPM (which is our design case) but the flow rate changes to 4 GPM at 80 PSI.The UPC AND IPC are stated at 60/80 PSI.So which value do I input ,the actual onsite faucet usage at 40 PSI or matching it with the base case at 80 PSI?In case I can use the actual design case at 40 PSI ,is there any requirement to provide the pressure testing report to USGBC? Please help!
Thank You.
