Fixture "Water Use" = Flow rate X Duration X Occupants X Daily uses
- The daily use number shall be increased to three if urinals are not installed in the room.
- Refer to Table A, Chapter 4 of the California Plumbing Code, for occupant load factors.
- Shower use by occupants depends on the type of use of a building or portion of a building. For example, the total occupant load for a health club, but only a fraction of the occupants in an office building as determined by the anticipated number of users.
- Kitchen faucet use is determined by the occupant load of the area served by the fixture.
- Use Worksheet WS-1 of the 2016 CALGreen Code to calculate baseline water.
