Hello! 

All mention of establishment periods refer to the no potable water/irrigation case (WEc1 Option 2), but what about for Option 1, 50% non-potable water use reduction?

My project consists of some landscaping at grade (2%) and the majority of landscaping on the podium level (18%) for a combined landscaped area that is about 20% of the site. 

Within the WEc1 "Thresholds" tab, there is a green button that reads "Submit". Are you supposed to click this button in order for the credit to be ready for review?

We are building on a previously developed site where there are many existing Redwood trees that will not be uprooted for the project.

We use 100% non-potable water in our project but the LEED v06 form still requires 50% reduction from baseline, but there is no calculator on the form and none separately available under Resources.

In case a given project is predicted to feed both the irrigation system and the flush discharges with harvested rainwater, which criteria shall be used to "divide" the rainwater contribution for ea

We are looking at this credit for our project and after reading a few posts and reviewing the WEc1 form in LEED online my question is; the NC 2009 reference guide states that "Reductions must be at

Can the following types of water, if stored in a rainwater cistern, contribute to credit compliance? - Water from building foundations (dewatering) pumped into the rainwater cistern, - AC condensa
