Sorry to post a LEED-related question, but I thought someone might have run into this in the past for EAp2 modeling using the developer control alternative compliance path calculator.
I posted this same question on LEEDUSER but thought I'd get more responses from the modeling community here!
I've done a number of Core and Shell models before, and always use the ACP calculator. However, something that I've noticed before but never understood is why the Revised Point threshold column is a single column and NOT separate revised thresholds for New and Existing. As an example: In a current project, I have a developer control percentage of 47%. It says that any savings over 13.8% gets you 6 pts (see chart below). This is a nice drop from the 18% required for a non-ACP path to get 6 pts for new construction projects. However, the non-ACP path for 6pts requires a renovation project to have 14%. In other words, the ACP only lowers the 6 pt threshold from 14% to 13.8% for renovations. Why does this happen? Is it just something you have to live with for renovations? Or is there a way you can pro-rate this to be valid for existing building renovations? Thanks!
