The project I am working on has three building as a whole. These three buildings will be defined as office use but designed as apartment style. It is defined as apartment-office building in Chinese building category. From the floor plan, the office space is like residential units. The project will choose packaged terminal air conditioner for its HVAC system, and combined heating power system for heating. Since the baseline of energy simulation has significant difference between residential and commercial project, is my project eligible to be defined as office rather than residential in energy simulation?

First thought - you probably need to treat this as three separate LEED projects under v3. Go read the minimum program requirements.
ASHRAE 90.1 defines residential as "spaces in buildings used primarily for living and sleeping." By that definition I don't think your buildings are residential.

I would look at registering the three projects as a "block" in LEED Online. I haven't done this so I don't know exactly how it works, but I think it would make sense here.

One more question, have you noticed that the simulation will much easier to achieve full points by comparing packaged terminal air conditioner to VAV?

Not sure I understand your question. In my experience it would be easier to show improvements against PTACs (ASHRAE system #1) than against packaged VAV (system #5).
