My project is a Mixed-Use development. It consists of 3 residential condominium towers erecting on a single podium building, which will function as a mall.

Currently this project is registered in LEED 2009 New Construction. However, during the middle of design stage, the owner decided to construct it into different phases: Phase 1, Podium Building; Phase 2, Tower 1; Phase 3, Tower 2; and Phase 4, Tower 3. Each tower varies in height but the average is 35 floors (counted from g/f of podium). The owner's intent is to make the Mall (Podium) operational even while the towers are still under construction.

In relation to the abovementioned project's new direction, do you think it is possible to consider a "transfer/change" of registration? Meaning, from the current LEED registration status i.e., LEED 2009 NC will be changed into Multiple Building / On-Campus. What certification strategy would best fit for the given project description? What are the cost implication for transfer/change of registration (from NC to Multiple Building NC)?
