Create a posting that includes:
- A screenshot of an interior view of your merged model from Model Coordination showing the HVAC elements.
- A brief paragraph discussing:
- any challenges that you encountered in this supply duct routing exercise
- whether your proposed design meets the project’s spatial design goals
- any recommendations to make the design more sustainable (and lower the heating and cooling loads
There are several challenges in this exercise, first is to coordinate with the structural model. At first, I thought 1 ft clearance for the supply duct is enough, but when I finished the exercise, I found it was too short and I have to bring the whole HVAC system down to an additional 1ft and 2 inches so it won’t intersect with the structural system, and the height of air terminals, therefore, was designed to be 7’ 10’’. Another challenge is to connect the air terminals to the duct system. When I used flex duct connection, in the floor plan it was connected but in 3D it was not, and I have to find out the unconnected air terminals and tried to connect them one by one.
I think my design meets the project’s spatial design goals besides the air terminals are lower than I expected but it is the maximum elevation I can get. I tried to design a clean look HVAC system and tried not to block the curtain walls.
To design more sustainable, I think we can design horizontal mullions or have a longer overhang for the curtain wall system to have more shading during the summer so we can reduce the cooling load.
