FAQs about WEc1 :

We are using non-potable water for irrigation. For drought conditions, can we hook up to a potable water source for backup and still earn this credit?

Can non-potable well water that is used for irrigation contribute to potable water reduction?

Can surface water, such as water from an irrigation ditch or a local creek, be used as nonpotable water?

Do interior planters count in the calculation?

NC-2009 WEc1:Water Efficient Landscaping

Water requirements much higher in LEED

The LEED form gives a certain amount of water based on the calculations. However, the landscape designer has calculated detailed water requirements and has showed the water requirements are much lower. Can the landscaper designer figure be used to size our rainwater tanks as the water is from rainwater only?

I don't really understand the question. The LEED Online form is designed to document credit compliance, not to be a tool for sizing your rainwater tanks. Your designer should have the tools to do that.However, if the LEED Online form is giving you output that seems to exceed your actual water requirements, then this could negatively affect the points you are earning for the credit. Examine the inputs and calculations to be sure that they are in line with your design.
