Water consumption calculation - showerhead flow rate pressure

NC-2009 WEp1:Water Use Reduction—20% Reduction
posted by  GPS Development   on 

I'm working on a LEED project in Asia. The water pressure for shower here is set at 3.5 bar (~50 psi). However, the baseline used by LEED is 2.5gpm at 80 psi.

posted by  Eric Webber  on 

If our project has three different kitchen sinks with varying flow rates (ie SK-1: 1.0GPM, SK-2: 1.5GPM etc), how do I enter the usage for the FTE in the project?

I saw a comment on this site that implied the water used for pot washing sinks and kitchen food prep sinks can be excluded from the calculations, can someone verify that for me?

Faucet flow rate test and restraining measure

Hi. As requested by the review team, we need to prove the faucet flow rate. However, we can not find any data from the manufacturer. We use a basin and a stopwatch to test the flow rate.

Use of bidets in an office bathroom for NC 2009 project

NC-2009 WEp1:Water Use Reduction—20% Reduction
posted by  Guillermo Brunzini  on 

As far as I know, bidets are considered process water fixtures, so do not need be included in the water saving calculation, is that correct?
