Hi,

we are currently certifying a building in Europe, where sanitary equipments are typically tested and certified according with its performance at 3 bar pressure. Sometimes it is possible to get this information (bu it is really hard!), but in this particular project, taps manufacturer only have performance measurements at 3 bar pressure.

Since calculations in LEED are made at 4 bar pressure, and we do not know our current performance at that pressure, shall we consider proposed equipments with water performance similar to baseline (in this case, 0,5 gpm)?

Regards,
