I´m working on a project that is a campus with 2 warehouses, an administrative building, a large dining room, a little auditorium and a changing room.

Metered showers and faucets appear to be rather clear based on the available LEED information and the new Water Use Reduction Calculator, but metered urinals appear to be overlooked.

Can someone confirm me that the use of faucet aerators is an allowed way to achieve WEp1 WE c3 for Leed CS v3 ? It's impossible to find a faucet with a so low flow rate in italy.

I'm working in a LEED CS Warehouse:non-refrigerant building, the project is divided in 2 main areas: office and warehouse.

Hi, I have doubts regarding showers for bicycle racks calculations for WEp1.

LEED-CS 2009 form WEp1 version 4.0 states the following: "Note: The flow rate for all pre-rinse spray valves must be less than or equal to 1.6 gpm.

What would be the absolute minimum that a LEED CS tenant agreement would have to specify to get some level of LEED certification?

I am working on a multi-residential building. Every apartments includes one bathtub. Are these calculated as Shower or ignored in the water use calculation?

We are employing 0.5 gpm lav fixtures with sensors and timed cut off at 10 seconds. Can we factor those to 0.125 gpm because the average use will be say 20 seconds?
