- 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)
I spent some time figuring out the height of the HVAC systems. They could not be above the ceiling, so their heights should be a little lower than 12’. I have also calculated the airflow so that there are enough supply diffusers placed in each space or zone. At first, I did not realize there were openings that needed to be avoided. I had to remove the ducts and diffusers around those openings.
I think I have met the project’s spatial design goals. I placed all the HVAC systems right below the ceiling, and they did not block important openings. All the spaces below the HVAC systems are not affected. Because the skylight on the second floor did not show up in the ceiling plan, I first placed some ducts there. However, these were later removed to create space for the glazing area.
To make the design more sustainable, there could be some more exterior shades and overhangs for the windows. There are many methods to reduce heating and cooling loads. For example, the occupancy rate could be adjusted for different types of spaces. Also, the operation schedule could be adjusted and even made motion-sensitive. For instance, the HVAC system will not be turned on if there is nobody in the space.
