In the original architectural program, groups did not HVAC systems into consideration. Because of various other reasons, the structural group adjusted the sizes of the original footprint of the building as well as the internal spaces of the building and did create spaces to accommodate HVAC system duct work.
The structural group created a centralized core for the building which did include space for vertical HVAC shafts to supply air to all the floors of the building. During the architecture portion of the project, the architect teams did consider a floor to floor height of 13' and and floor to ceiling height of 10' to create space for a 3 foot space for the horizontal ducts. The basement and rooftop mechanical floors created during the structural portion of the assignment did prove to be of substantial size to house the necessary mechanical systems.
The HVAC group decided that an air handling unit, 2 boilers, and 2 chillers would be located in the basement mechanical floor of the building where 2 additional Chillers, Boilers, and an Air Handling Unit would be located within the rooftop mechanical floor. In addition to these components, 3 additional AHU's were placed on floors 5, 10, and 15 in order to supple adequate air flow. Because the structural group did consider spacing for ducts within the core of the system, no major changes were needed to be made. Since the general foot print of the building was changed, enough space was allocated for the duct work needed to house our system, creating no major issues.
