Your Design Journal entries for this module should highlight your design thinking and analysis results that influenced your decisions about:

  • your overall HVAC system strategy
  • your heating strategy and how you implemented it in your design
  • your cooling strategy and how you implemented it
  • any special HVAC system challenges that you encountered

For my building I used an HVAC system with AHU’s located at every 2 floors, with the exceptions of the 6th and 7th floor since those floors are notably smaller in square footage. The AHU’s will be used for both cooling and heating of the building. Since I had already allocated a shaft for ductwork I was able to utilize that to route across the various floors. Unfortunately my shaft was located near the elevators so I had to base my routing around them. I did not model the return air but there was room in my shafts to do so. A challenge I encountered was with the atrium I had modeled and whether or not I should route my duct inside or outside the corridors. I opted for running my duct outside the corridors for the most part in order to make room for any future utilities to take the space.
