I have been asked to provide IAQ Testing for LDP, and am having trouble finding the distinctions between the normal pre-occupancy sampling for credit 3.2 and the during occupancy sampling of LDP.

As we reported on BuildingGreen.com (see Dynamic Plaque Piloted as LEED Performance Path)

As hard as LEED certification is for a manufacturing facility, LDP was nearly impossible. I did the 30 day trial and never achieved a score higher than 8.

Hi, For existing building LEED certification which type of data/document required upload to LEED ARC & what will be the timeline & process ? If any example it will be very good for me.
