Hi, I'm now working on a project under LEED certification according to NC v2009. We collect rainwater to provide non-potable water to wc. May we consider this water in WEp1 and WEc3 calculation?

We're proposing 0.5 gpm faucts for a project and the client is demanding more information from other facilities on these faucets.

Hi, Can anyone please advise on the following; Do shower flow rates need to be calculated at 80 psi and installed at 80 psi? The same for for faucets, do flow rates need to be calculated at 60 p

We have an office building/warehouse that also has an exhibit/social gathering space with a large number of transients. Some of the building users are closest to unisex toilets only.

Dear Since I have a problem with BETA version for WEp1, the form did not calculated the percentage correctly, I´ve decided to use the v06 form calculator, well...

I am conducting a survey in affiliation with University of Cincinnati for my Master's thesis which would take just 10-15 minutes of your time.

Review comments have requested that I include the pre-rinse spray valve in the hotel kitchen in my water usage calculations.

Hello, We just got our review back for a new construction of an office building. For this credit we had a comment from the reviewer, that we have never encounter before.

Should decorative fountains be documented under any water-related credits such as this one or the water-efficient landscaping credit?
