Dear All,
A single building consists of:
10400 m2 commercial areas (retail & restaurant) at ground level floors
11000 m2 residential areas (multifamily) at the 9 above grade floors
12000 m2 underground parking
We are considering using the LEED-CS rating system here. Do you think this is possible?
Thank you,

It may depend on the level of finish for the apartments and whether they are for sale or for rent. Many mixed-use commercial and residential buildings have pursued LEED NC, especially when the apartments are fairly complete in the build out of their interior walls, ceilings, plumbing, electrical, etc. as they would be for rental apartments or many for-sale condos. The key issues is how much control or influence the project owner has over the choices of fixtures and finishes. Some projects that allow a fair amount of customizing will still limit the buyers choices to "LEED compliant" fixtures and finishes.
In some cases, apartments may be sold that are truly a raw shell - no interior walls, finishes, plumbing fixtures, appliances, etc. Historically there have been very few CS residential projects, but if you go through the rating system selection tables in the LEED Online process for registering a new project, you'll see some fairly clear guidelines for scope of work that makes NC or CS more appropriate.

Thank you for the reply David. If we choose the NC system, then how to account for the tenant fit-outs in the retail areas in credits such as Optimize Energy Performance? Would it be possible to apply a Sales / Lease Agreement in a NC project so that the tenants are enforced to use energy efficient equipment?

Omer, based on the LEED Reference Guide for BDC, lease agreements can be used to get credit for tenant spaces under EAp2 and EAc1.
