LEED rating for a penthouse on top of an existing building

I am working on a new two storey penthouse project which is 2900sqft and located on the roof top of a low-rise existing gym and a car park building. the project is located in Asia. the client wishes to pursue LEED rating for this penthouse unit. Although LEED homes will be applicable, considering it is outside US, it will be complicated. I am not sure about applicability of NC as some of the credits on SS category might not be relevant as it is located on a rooftop. Any suggestions of a relevant rating system would be appreciated.
