Commercial office refurbishment: which rating system?

One of our clients is starting a major refurbishment of an office building. Main characteristics of this operation are:

1. Building Owner: the client itself;
2. Building occupancy: client staff (almost 100% of the building – only a tenancy area is foreseen: small bar/cafeteria);
3. Main building use: offices;
4. GFA: around 10.000 m²;
5. Area included in the refurbishment operation: around 9.000 m²;
6. Interventions included in the refurbishment operation:
   1. interior fit-out: partitions and ceilings (almost all spaces);
   2. lighting system;
   3. fan-coils, air-handling units, pipes and accessories;
   4. chiller (replacement of one of the two chillers actually installed);
   5. under evaluation: façade refurbishment (can include the replacement of actual glazing and/or application of shading devices).

The question is: which LEED rating system is more appropriate for this intervention: LEED BD+C: New Construction and Major Renovation or LEED ID+C: Commercial Interiors ?
