I have a major renovation project that has existing plumbing fixtures that will remain. These fixtures have been tested, however, the water pressure at the project site is well below the Energy Policy Act of 1992 water pressure test rates. It appears that the water pressure requirement is only applicable to non-metered flow fixtures? So test results from the toilets, urinals, and metered lavatories can be used, correct? But, there is one pantry faucet that is not metered and the showers are not metered. How can I account for these fixtures in the water calculations? I don't see LI #829 (http://www.usgbc.org/content/li-829) as an applicable option. The client is not going to purchase, install, and test "baseline" fixtures at the project for LEED water efficiency calculations. Any advice would be greatly appreciated!
