We will start a residential project (more then 4 stories) The client is a developer who will sell and rent out the appartments. Does this mean that it needs to be a LEED Core and Shell rating System? Or should it be a New Construction ?

While it's possible for a residential project with 4 stories or more to pursue LEED Core and Shell (CS) it's not very common. The apartments would need to be empty shells with almost no interior walls, plumbing fixtures, finishes, or lighting fixtures.
If the project is a new building with more than 60% of "interior finishes included in the project scope: flooring, ceiling, wall applications, Mechanical, Electrical, Plumbing (MEP) fixtures" (from LOL v3 Rating System Selection Table 4) than you would follow New Construction (NC); If less than 60%, follow Core and Shell (CS). (MEP fixtures would include heating and cooling units, ventilation fans, light switches, basic light fixtures, toilets, sinks, showers, etc.)
We haven't seen a specific definition for a residential projects for when they should be NC or CS, or how to calculate the % of project scope for interior finishes. Going through the registration process on LEED Online mentioned above, and clicking the links in the Rating System Selection may help explain. Look for Table 3 Core – Interior Guidelines and Table 4 Core and Shell Eligibility, these shows the % of work being done on structure, mechanical systems, finishes, etc.
Most high rise residential projects have been certified under LEED NC, since there are walls separating each apartment, and usually most of the bath and kitchen plumbing fixtures and finishes such as interior doors, ceilings, some lights, etc. are installed by the developer.
Some mid-rise projects with 4-6 stories choose to use LEED-Homes Multi-Family Mid-rise if there is a LEED Homes provider in their geographic region. See: http://www.usgbc.org/ShowFile.aspx?DocumentID=7982

Following on this line of thought, we have a high rise building project about to start. It is more than 60% office space for lease (Core and Shell) and less than 40% apartments, to be built above the offices. They will be fit out and ready for use, but the bulk of the building is office. From other postings it seems that it should be registered as one project, LEED CS 2009.
We will make two energy models with two ASHRAE base lines, because the systems and fuel will be different, and then combine the results of each model.
Does that sound correct?
(It is also similar to a more recent posting about mixed use with residential and office CS.)
