Analysis of peak heating and cooling loads to determine how many air terminals each room with require:
My building is located in a moderate-cool climate, where heating will be most important to combat external temperature changes. However, due to the high number of people the building will accommodate, cooling will also be important.
For cooling, the primary line of defense will be natural. By implementing window glazing and exterior shading, I plan to reduce solar radiation from entering the building. Similarly, I plan to use fans to help distribute air and keep temperatures low, particularly in the large exhibits and kids space. There are also two electric air handlers on either side of the building to accommodate each wing. Similar to cooling, heat will be distributed via the two electric air handlers on either side of the structure.
As with much of my design, the biggest challenge came from the central atrium, because it is completely open there is not much room to hide ductwork. The solution I came up with was to put a ring of duct work aligned with the 4th floor which will supply air to the entire atrium, and a half-ring of vents at the 1st floor for return air. I believe these ducts plus the overflow from the ductwork in the large wing will supply enough air and ventilation to the space, but this might require further adjustment.
