Hi all, We have a tight urban condition with a large expanse of exterior green wall. Any thoughts on what to use for a baseline for this? Can we use an equivalent area of lawn? There is no "conventional" version of a green wall so not sure what to compare it to. It's going to be irrigated with harvested rainwater and condensate but we still need to demonstrate the 50% reduction in irrigation. Thoughts appreciated!

Janika, is the green wall built onsite, or a product specified from a manufacturer? If the latter, perhaps you could ask the manufacturer what plantings most of their customers use. Lawn doesn't seem quite right.

Hi Tristan, Thanks for your reply. It's a custom green wall built on site. I received comment back from GBCI that we'll have to baseline it with a narrative approach in showing how the strategy meets the intent of the credit and compares to a "conventional" planting plan, whatever that means. We'll probably see if we can find a manufactured system we can compare to and see how that goes. Thanks, Janika
