I assume an ablution fixture used to wash before entering a prayer room would have to be considered in the water use calculations. What would the baseline rate of the fixture be? The same as a public lavatory?

Well, Following efficient practices is always a great idea in general but still i think its not covered under the scope here. i may argue that it may fall under Process water category which also includes (Mop sinks, janitor sinks, swimming pools, bidets, and safety showers) because it doesn't have similar usage pattern as a public lavatory (water runs for longer periods). But a second opinion would be good here.

Public and private lavatory faucets encompass all sinks used primarily for hand-washing regardless of location (February 2, 2011 Addenda); so if the ablution fixture described above is used primarily for hand washing then it would need to be included.

Hi Carlie, its an activity that involves face, hand and feet washing, its not conventional.

Agree regarding the face and feet washing, so was leaving this up to the project team on whether the fixture was primarily used for hand washing. If not, then I could see the fixture being excluded since it is not representative of typical hand washing.

While I agree it's not a conventional fixture, it is a fixture that is used while running, and not to fill a basin and then use (like a tub or janitor sink). So, I believe it should be included in the calcs. However, I'm not sure it can be included as LEED does not define a baseline for such a fixture. I imagine one could compare it to the flow rate of either a shower or lavatory. But, because the LEED calcs are so specific to each fixture type, an ablution fixture might have to be excluded. Thanks for your thoughts.
