We have an administration complex consisting of two basement levels having parking and utility rooms, and above ground a 4-storey podium and a tower both serving as office spaces. the two basement levels are shared between the podium and tower and extend over their combined area. The only link between the tower and podium above ground is a corridor/bridge at several floors, otherwise they are independent structures. All components will be constructed at the same time. and will be served from a utility plant outside the project site. The client has requested to certify only the tower as LEED and exclude the basement and podium from the certification. Is this approach acceptable and if yes how do we define the project boundary. Thank you in advance.
