Is there a lower limit to the lav flow rate below 0.5gpm that USGBC will accept? I saw something posted on the EPA's website awhile back, but am not finding it now.

If we were to calculate the average flush rate of a dual flush toilet (with urinals present in the space) we use the example average flow rate equation provided by USGBC in their Appendix A water c

Does anyone know what the basis is for the plumbing fixture uses by occupancy type? For example - 3 water closet uses for each female FTE, etc.

Hi If water fixtures are not part of the project scope and are not considered for the LEED submission, can the project still pursue SSc3.2 due to existing showers in the base building? I thought

I have a LEED-CI project in which there is one toilet that is EXISTING in the base building and NOT A PART OF THE SCOPE of the tenant improvement.

I am a little confused by what i have read concerning WEp1 and what fixtures are being used by a tenant vs what is in the scope. I have a CS poject where I will acheive 32% water savings.

I have faucets in a locker / changing room. Reading the credit language it doesn't explicitly state that they should / shouldn't be included? Any Idea?

Hi Would Sensor activated flush fixtures like urinals and WCs have the same flow rate calulations as a sensor type flow fixture? Would it follow the default 12sec / 60 cycle?

Hi, I would like to know if anyone has any information (case study, formal review, experience with) of any of the hybrid urinals currently available in the market.

Our project occupies (4) out of (10) floors of a building which was LEED 2.0 certified. We are attempting Silver under LEED CI 2009.
