We had an initial mis-characterization of our flow fixtures (we thought they were private, not public), and now with everything properly calculated we are at 29.47% reduction from base case....

My project has achieved a 82% savings in flow & flush fixtures through recycling 100% of the waste water and reusing it for WC and urinal flushing.

We documented this with a...

Do I have to account for the water use of existing fixtures to remain on a major renovation (football stadium) under LEED NC, if they are within the LEED boundary, but the spaces/structures they...

Our project is a 50% office- 50% lab building. Are laboratory sinks to be accounted for in this credit calculation?

Thanks.

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...

When we sent the WE credit for review for our project, we sent a water use calculation stating that the potable water usage in the project has been reduced by 43% from a calculated baseline...

I have completed the form for WEp1 & WEc2. When I go to finish WEc3 it doesn't show the savings from the...

Hi all,

For some background on our project:

- we have on-site rainwater capture as well as connection to a municipal non-potable water supply
- the municipal water is used to...

The water use of dual flow faucets that has two positions, would be a weighted average of both?
1º: 1,58 gpm
2º: 2,37 gpm
=1,97 gpm?

As a dual flush toilet water use is...

Is there a calculator tool or methodology that we should use when submitting our annual rainwater collection (kGal) calculations for LEED?

Our calculations are currently based on BS 8525...
