Abstract: A structure for a multi-story building comprises a first passageway constructed internally within a building being configured with a mount for a ducted condenser unit (DCU) of a split type, unitary air conditioning system to achieve a desired level of condenser based heat dissipation and with a plurality of penetrations to accommodate a conduit through which refrigerant circulates between inside and outside units of the air conditioning system; and a second passageway constructed internally within the building for receiving air discharged from the DCU the second passageway terminating at an opening of the building through which the discharged air is exhausted to the atmosphere. The passageways have walls that are essentially closed, with the exception of the wall that is formed with an opening through which the discharged air flows. One or both of the first and second passageways upwardly extends across at least two stories of the building.
