We are having trouble finding EPAct-compliant fixtures. Is that a problem?

Where can I find a clear meaning of "public" and "private" as relevant to lavatory faucets?

Our project is a factory with historically a 95% male workforce. The restroom design accounts for this. Can I argue that the male/female gender ratio is different than 50/50?

Can I include process water savings in order to earn an Exemplary Performance point?

Will the reviewers accept a spreadsheet as a plumbing fixture schedule in lieu of the plans from the Construction Documents?

In LEED review comments I've been referred to the Water Use Reduction Additional Guidance document. I didn't know this was a required reference document.

Should I include bar sinks? What about mop sinks or janitor sinks? Swimming pools? Safety showers? Bidets? Tub spouts?

We provided new showers in our project to comply with the alternative transportation credit. Should they be considered in WEp1 calculations?

Can you explain the 12-second duration for metering faucets?

Can I use a nonpotable water source to contribute to WEp1 compliance?

NC-2009 WEp1:Water Use Reduction—20% Reduction

WE Pr1 - What does ADO stand for in the Process Water Use Sect?

We are using LEED 2009 for Retail: NC+MR templates, for one of our projects. In WE Pre-requisite 1Template, there is Process Water Use section. One of the column is named ADO. What does ADO stand for? What we are supposed to fill in here? If any one has answer for this, we will apreciate it. Thanks.

The official answer from GBCI was that “ADO” stands for “Annual Days of Operation” per USGBC. Thanks for your replies, I hope it can help you.
