NC-2009 WEp1: Water Use Reduction—20% Reduction
We are certifying a project in Spain. The faucets in the restrooms need to have a flowrate of 1.9Liter per minute (0.5 GPM) We have been unable so far to find a supplier that has such a low flow rate. (The usual is 6L per minute) Does anyone know of a brand & model that is available in Spain or in Europe for that matter that we can install in the project?
Thanks

Can you explain the 12-second duration for metering faucets?
Can I use a nonpotable water source to contribute to WEp1 compliance?
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?
Are shower duration controls an acceptable water-saving strategy?
Can I include process water savings in order to earn an Exemplary Performance point?

I’m working with LEED projects in Sweden and face the same problem. To be able to meet the total reduction of 20% we compensate with very low flow toilets compared to the baseline (0,7gpm).
If you are interested in credit 3, I don’t have a good answer; I don’t understand how you can have such a low flow, even if you mix the water with air. You get a much better value in the calculations if you install faucets whit sensors, but those are more expensive.
Alternatively look for taps that have a limited flow when you put it on but don’t hold it. If you need to have a bigger flow you must hold the handle up (if you need to fill a can or something).

Veronika, looks like we found 2 Liter per minute faucets from the brand Presto....

The architect in this project now proposes a faucet with a sensor that only turns on when your hands are under the faucet. How do you calculate the gallons per cycle on a faucet like this?

You should also check out Neopearl. Quite impressive values, even 0,35gpm.
