we are putting a proposal for a new project that is 70% residential (about 10 stories high), 20% retail and 10% hotel

all the residential buildings are separate identity buildings while they are all connected at lower levels with the retail I mentioned above

all residential buildings are identical in nature... so we can go for group certification but it says in the description that all constituent buildings have to classify under same LEED rating system

can you please help us in deciding what rating system we should go for...

(early concerns like will we have to do separate assessments for each building and thus separate energy models etc)

Thank you for your help
