Glenn KatzFor my HVAC strategy, I decided to go for Air transport systems. I wanted to take advantage of my flat roof to place my air handler at the top of the structure, in a convenient location such that it minimizes its visibility from the ground floor. Because my structure is almost two separate buildings, I decided to go for two separate handlers. I then modeled ducts that went from the air handler to the mechanical room. From there, my ducts run primarily on the central halways, with further extensions to the sides if necessary. Since most of my building will have exposed timber structure, I wanted to minimize the visual impact of my ducts by placing them in the hallway, with only small ducts to the ides to connect with the air terminals of each room. I also divided each structure of the building in north and south zone, to better allocate the distribution of my duct system. Because my mechanical rooms are fairly small, one challenge I encountered was making sure I modeled the ducts correctly so that they an angle big enough to rotate and turn (either to different sides within a level or as they went up and down in elevation).
