I am working on a hotel project, which would use standard fixtures (no high-efficiency fixtures), but would still earn 2 points under WEc2, and 2 points under WEc3 due to utilizing recycled gray wa

I'm working on a LEED project in Asia. The water pressure for shower here is set at 3.5 bar (~50 psi). However, the baseline used by LEED is 2.5gpm at 80 psi.

I have a major renovation project that has existing plumbing fixtures that will remain.

If our project has three different kitchen sinks with varying flow rates (ie SK-1: 1.0GPM, SK-2: 1.5GPM etc), how do I enter the usage for the FTE in the project?

Hi! We have a data sheet from a shower which specifies a flow of 7,8 liters/minute at a pressure of 5.5 kgf/cm2 (which is equivalent to 5,39 Bar or 78 PSI).

The project I am working on is an office building located in middle east. the Washroom water closets all has water jets or a bun gun fixture for washing purpose instead of using toilet paper.

when I have an addition project do I have to demonstrate compliance for the new addition and renovated areas or does it have to be applied to all areas?

In v2009 WEp1 calculator, the toilet is divided by gender (male and female. If the % male-female is 50%-50%, it might point to 50% in "percent of occupants" cell each.

Hello, I have two questions about this prerequisite: 1st. Are the flow described in the baseline a maximum flow for the project ?
