Parking space separate problem

Dear all, Our project is a synthesized building with office, shopping mall and residence. Only the part of the office will apply for the LEED certification. (The office building is vertical attached with shopping mall) All parking area is located underground. On the basis of governement approval and local parking requirement, the project must provide 1360 parking lots which 392 lots for office building. (8 lots / 10763.91 sf) The project design meets excactly 1360 parking lots underground. Howerver, we don't know how to prove that the office project parking lots meet the LEED requirement, because all the parking lots is provided in the same parking space. Could we seperate the 392 lots for the office to prove the parking capacity of the office meets the LEED requirements? The conventional implementation of this building type is to place some signals indicating this part of parking space is only provided for the office building, could this implementation meet the LEED requirements? Thank you
