Hi! In my project, certain areas just has trees and ground cover. For these areas , i will use the landscape factors for mixed trees, shrubs and groundcovers? Thank you!

What should the reference evapotranspiration rate (ETo) be expressed on the online form as? inches/month?

I would like to know, where I can find a good source for the specific landscape factors (species-, density- and microclimate factor) of plants for the calculations in the baseline case. Is it even

I should know this, but.... Is it OK to run the WEc1 calcs with the same landscaped area (in square feet), but with different plantings in the baseline and design cases?

Do the different species of plants need to be listed individually on the form or does 'Mixed' suffice? The green roof consists of a mix of trees, shrubs, and flowers. Thanks!

Hi, I have been advised that the sedum plants would meet this credit on green roofs due to the fact that the plants would be indigenous for landscaping in general.

I have a project that is considering installing green wall/vertical garden. We would like to pursue WEc1. Water Efficient Landscaping, Option 2 (No Potable Water Use on Irrigation).
