Hello, would anyone know what is the approach to take in oder to identify the Design Flush Rates for fixtures that one does know the make and have no specifications for, in order to perfrom the cal

I have a project in a peculiar situation that is not addressed outright by the guidelines language and I can use some help in interpreting the rules. 

I have a lavatory faucet that are automatically controlled (sensor control) and a flow rate of 5 l per minute. In accordance to the LEED manual the baseline is 1.9 l per minte.

 The potential way to target water reduction is by monitoring the water use for flushing. Is it necessary to install a water meter for each piping that goes to separate toilets?

Hi, I am quite confused as to how to calculate compliance for Option 2 Metered Water Use. We have the consumption data for 12 months for a building however the calculator is only for Option 1.

If the percentage below water consumption maximum is calculated to be -22% (not 0%) by using the calculator, is the pre-requisite met or not?

I am a little confused here: Credit language states the following: • Meter fixtures and fittings and record metered data for one year to establish a water-use baseline. • For projects with at lea

When introducing the design flow rate values in the indoor water calculator for option 1 calculated water use, we should use the flow rate fixtures values associated to the actual facility pressur

For multifamily buildings where the residents are responsible for purchasing and installing fixtures, for Option 1 do I need to survey every fixture in every apartment?

If we had submeters installed for more then 80% fixtures in the building but the building is unoccupied during the perfomance period we must use (as the reference guide seems to state) the optio
