Challenges:
The duct routing exercise for me is quite interesting, In the design, I have recognized that the two types of ducts (supply air and return air) could clash if it is hung at the same height. To avoid clashing, I aligned the two systems at two different heights, but still maintain the air terminal clearance height to the floor at 8’ 6’’.
It is quite difficult for me to model in the vertical axis the duct and get familiar with the new type of modeling ( I have never try model the HVAC system before), however, when I get familiar with that, it is a quite smooth process
I believe that my proposed design meets the project’s spatial design goals. I think that I could even raise the duct a little bit higher if it was needed so we could gain further ceiling height. The typical section width of the main ducts is 12’’x12’’ while the arterial ducts are 6’’x6’’. The size of the ducts can be changed to meet the design requirement, however, there are several factors that will affect the final sizing, such as the number of people (floor occupation ratio), air velocity, insulation, temperature, etc. that will need input from an engineer. In this exercise, I try to simplify the system and hereby I just give a draft estimation size of the system, of course, we can change the duct sizing at anytime
However, as the mullion wall is attached into the structural floor surface, I think this could be changed by reduce the mullion wall height to the ceiling height to avoid clashing with the ducting.
Proposal:
I think the design should have a ceiling, maybe a wooden bar ceiling to cover the ducting system. This makes the building and the interior space more aesthetic, moreover, brings a warm feeling to the spaces and occupants while doesn't affect the HVAC system
