Abstract: A system for conditioning air in a structure includes a first conditioning system and a second conditioning system. The first conditioning system is capable of supplying conditioned air to a first space of the structure. The first space is enclosed, at least in part, by one or more external walls. The second conditioning system is capable of supplying conditioned air to a second space of the structure that is located above the first space. The second space is enclosed, at least in part, by a roof that is sealed to prevent a flow of air between the second space and an outside environment. The first space and the second space are separated by a ceiling that permits thermal energy to pass between the first space and the second space.
