Hello,
The guidance is not really clear on what to put in the baseline case. It only says that we need to specify typical landscaping practices.
Do we need to document these typical landscaping practices ?
Thanks,
You rely on LEEDuser. Can we rely on you?

George, LEEDuser (see the Checklists tab above) and the LEED Reference Guide give a number of factors that need to be counted for the baseline case, and how to calculate these. Which of these do you have a question about?

Correct me if I'm wrong. I found it a little confusing too. Based on everything I've seen about this "baseline case", it consists of required trees and shrubs for any local buffer/ streetscape/ forest conservation code requirements, and lawn. If you have no local code requirements for vegetation, your baseline will be all of your vegetated square footage shown as lawn. Then the design case is obviously that same total vegetated square footage, but with a break down of everything you graciously "replaced" the lawn with.

Tristan,
When referring to the baseline, the Guidance states that Ks, Kd and IE must be set to average values, Kmc and ETo should be the same in Design and Baseline, and the scheme should reflect typical practices in the region. What if typical practices in the region consist of shrubs and lawn and my design consist solely of trees:
1) Do I need to document the typical practices in the region ?(i.e. get a written confirmation from a local authority )
2) How can Kmc be the same if the species are different in the baseline and design ? (as per above)
Many thanks,
My question is, if for instance my design consist of drought resistant shrubs and native trees, an

George, you do not need to document typical practices in the region. These can be assumed.I think Kmc can be the same, yes.
