One of our project have G+7 floor. This is the existing building which had operated as office. Now this building is bought by our client and going to make as a data centre. They are not making any change in the envelope except changing the glass. However they are renovating all
HVAC, Electrical, plumbing etc. Could you please help us to select whethere this building will come under LEED NC 2009 or LEED CI 2009? As a data centre the equipment load will be maximum, therefore acheiving acheiving LEED EA Pr1.0 will be possible or not? Thanks in advance for your reply.

Ramesh, based on the scope of the renovation and full owner occupancy, it sounds like an NC project to me.

One of the other project have 3 blocks and each blocks having G+2 floor. The client is not owner of the building, but they have lease agreement with the owner. 100% of the building area will be utilised by our client only. Here they are not changing any envelope or exterior except changing the glass. They are not changing the water fixture. But they are renovating whole HVAC (including chiller), electrical system, and interior layout. They are not doing any changes in sewage treatment plant, stormwater design etc. This building will be used as office with lab. Could you please tell me which rating system will be suitable for the project having the above details.Will it be in LEED CI or LEED NC?

We just asked GBCI that exact question (your first one) and here is the response. We're going with CI still because we aren't changing the envelope, site, and structure.
It really comes down to what sort of mechanical work is included in the project scope based on the definitions of "alteration" and "major renovation" in the Rating System Selection Policy. It is likely that the project is not actually doing a "major renovation" for 40% or more of the gross floor area (stated in line item #2), and much of the work could be considered "alterations" – be sure to evaluate your project scope to clearly identify if you are in fact doing a major renovation or simply alterations.
The project team could use CI provided that are not doing any work to the exterior shell or the primary structural components of the building. The key statement is 2) the same entity is conducting new construction or major renovation in 40% or more of the gross floor area of the building. If you are doing your CI space, and also doing what is considered a major renovation on at least 40% or more of the gross flore area of the building, only then would you be required to do NC.
