We have been working on our first LEED project in Thailand. We have been involved in the project since the beginning. It will take roughly 2.5 years for building design and construction (1.5 year as of today). Therefore, with the time left, we decided to do split review for timeline and reviews.

My question is that when is the most appropriate period to submit for design review phase.
LOv.3 says we can submit for design review phase once we complete all PI forms and have at least one design prerequisite completed. We can do it now if we stick with LOv.3 minimum requirements for design review submittal. However, in the timeline diagram, it suggests submitting design review during occupancy permit period.
How important is it to wait until that period? From your experience, are there any credit that we should complete before submitting for design review?
