Convention Center / Hotel One Big Building

I was surprised to learn that there is only one central location for all of
the Convention Center facility's heating and cooling; these units will serve the entire Marriott Hotel and the Convention Center.

The heating and cooling will be distributed by two four-pipe loops, two for heating and two for cooling, separated into zones.

The heaters and chillers will be located in the basement of the hotel tower. A cooling tower will be installed on the roof of the hotel tower. And air handlers will be located throughout the building, which will transfer either the heat or the cooling from the pipes into specific areas of the facility. Three of the largest air handlers are easily visible from the parking garage, on the roof above the loading docks.

The fact that the entire facility is dependent upon a single heating and cooling system proves that this is in reality only one extremely large building. There is no separate hotel and/or convention center; it is one great big building.
