We are working on a very large, core and shell project that the owner will not share the tenant agreement with our team. The minimum code requirements are based on IECC 2012/ASHRAE 90.1-2010. We were instructed to design the dedicated outdoor air unit for the building (common and tenant) to accommodate variable refrigerant flow system. The common area HVAC system is a variable refrigerant flow system.
First the Code question…
Is it correct to assume that the baseline lighting is based on ASHRAE 90.1-2007 and proposed lighting is ASHRAE 90.1-2010 along with the new daylighting requirements in ASHRAE?
Second the tenant improvement question…
Is it correct to assume that the proposed mechanical system for the tenant is a variable refrigerant flow system?
I welcome your thoughts.

Code - yes and yes.
TI - No. You cannot claim any savings related to the tenant spaces without the requirements being in the tenant lease agreement or without them being designed as part of the CS submission. Without one of those two you must model the tenant space HVAC identical to the baseline.
