A large office building is being certified using LEED Core & Shell.
The building will have only one water supply source (municipal network). This water will be invoiced to the common services. Common services will supply water to all tenant spaces (3 - 5 per floor), that will be endowed with their own WCs.
Water Metering Credit (LEED v4 BD+C) implies the measurement of at least two of the following:
- Indoor plumbing fixtures
- Domestic Hot Water
- Reclaimed water
- Other process water
As the Water Metering Credit does not describe any Rating System variation for the Core & Shell, credit compliance can be achieved without installing water meters for each tenant if water meters are installed to meter:
- all irrigation uses
- all boilers water make-up
Is this interpretation correct ?
