Water Efficiency 1.2 - Water Efficient Landscaping - No Potable Use or No Irrigation
January 30, 2008 – 8:40pmNo Potable Use or No Irrigation
Intention:
- Limit or eliminate potable water (drinking water) use for landscape irrigation.
- Limit or eliminate use of natural surfaces for landscape irrigation.
Implementation:
- Option 1: do not use any potable water
- Option 2: do not use any irrigation system
- For landscaping, use following methods:
- Captured Rainwater
- Recycled wastewater
- Recycled graywater
- Treated water
- Minimize site area by:
- limiting turf areas
- using landscaping that doesn’t require permanent irrigation systems
- temporary irrigation ok (for plant establishment) if removed after 1 year of installation
- mulching & mowing
Codes/Standards Applied:
- none
Extra Credit:
- none
Submittal Phase:
- design

Thanks for pervious answer.
If one project’s landscape can have no potable water use(means reduce by 100% > 50%), so it can get the both WE1.2 credit and WE1.1 credit. Is this right?
Thanks

Pat,
I found this answer. WE1.2 is the additional point to WE1.1. So once achieve WE1.2 should also achieve WE1.1.
Thanks

In the Reference Guide, they show example calculation tables for both the baseline case and the design case. Is it required to complete these tables for your project and submit them as part of the credit submittal process? The submittal template and the reference guide do not specifically say that they are required, but then why do they show the examples? Just for clarification of calculation method?

Does green roof irrigation count for the water efficiency credit? For instance, if everything on a site will be non-irrigated except the roof. Is it possible to still get eh WE 1.1 and 1.2 credits?

Pat,
As part of a CIR - WE c1 Ruling on 12/13/2007, the answer includes…
It should be noted that, in addition to using only non-potable water for irrigation, the project must demonstrate a 50% reduction in total irrigation water consumption from a baseline case in order to earn both WEc1.1 and WEc1.2.
This should contribute to answer fully Chen’s question
Any comments?
