Does anyone have any idea what these standards are or where they can be found? The European water label gives its highest rating (Green) to WC taps with a flow of 6 liter/minute or less. As the SI standard is 2 liter/minute it seems highly unlikely that LEED would allow this to be used as a baseline.
When I check the box in the 2009 Water Use Reduction Calculator it does not appear to change the baseline; however the baseline in the calculator is 1.9 liter/minute while the credit requirements list it as 2.0 liter/minute for SI projects.
Any help or guidance anyone could over would be very welcome!
