My client has an existing 500,000 sf warehouse structure constructed in 2005. The tenant recently finished a 10,000 sf office build out within the structure. The tenant wants to construct another 50,000 sf office structure within the warehouse and desire for it to be constructed as a LEED accredited project. I have researched, but it is not totally clear which certification program this would come under. Please clarify if it should be NC, CI or is it EB.
