We have a project where we have irrigation, restaurant tenants, indoor fixtures and service sinks. The 1st 2 are easily metered, but it is not easy to separate the indoor fixtures and service sinks. Our building is a 20 storey office tower, each floor has one supply line serving (1) service sink (2) wall mounted fixture for cleaning and (3) pantry and M/F restrooms (fixtures described in WEp2/WEc2).
After our 1st submission we just got a comment from the LEED Reviewer:
" The documentation does not confirm that the non-fixture usage (e.g. service sinks, etc.) is measured and can be deducted from the measured total water consumption of the building and grounds to measure the usage of the indoor plumbing fixtures (described in WEp Indoor Water Use Reduction)."
Does that mean that in order to acheive the credit we would have to have at least 1 meter per floor for either "non fixture usage" OR "indoor plumbing fixtures"?

Hi Timothy, we just had a design review of a project with the same comment from the LEED Reviewer. Have you had any luck figuring out how to address this observation to meet the requirement?

We recently had a similar comment. For our project GBCI confirmed that point of use submeters for the fixtures in question (in our case service sinks and water coolers) would be an acceptable method for capturing their usage.
