However, only main arteries re shown here. The walls have three depths: .66m, .33m, and .165m. The .66 and .33 walls have built-in ducting but not the .165 walls. Bloody big AC units on the Service level (and in top of the warehouse block) push the air down the main ducts and into the built-in ducting, where they come out in vents. Other vents and ducting take the air either back up to the service level to be reconditions, or outside.
Honestly you wouldn't believe how hard it is to find design guidelines for HVAC that aren't either too vague, or trying to selling you some package deal. Everything became a lot easier after I created the Service Level - it was the missing bit of the puzzle. .
