HVAC System 8 Baseline

Hi all, Currently I have a project in Malaysia that is going for LEED Core and Shell (2009), the project consists of multiple buildings but will be certified under one certificate. The project has 1 block of office tower (18 floors), 2 blocks of serviced apartment (28 floors each), 2 retail blocks (3 and 5 floors respectively). This project will be using the baseline of System 8-VAV with PFP Boxes. Could you please advise what would be the baseline COP of the chilled water system? Referring to Table 6.8.1C in ASHRAE 90.1-2007, can I use the COP for “air cooled, with condenser, electrical operated” which is at COP=2.8? My proposed design HVAC system is using VRV system or inverter multi split. However, based on clause G3.1.3.7, I must use the centrifugal chiller as my baseline. If this is the case, my building will not be qualified as LEED Building as it is very difficult for me to get the minimum 10% savings since my baseline COP would be 6.10. Can you please kindly advise how can I get the minimum 10% savings if my HVAC is VRV system? Thanks.
