Quick question regarding the building section vignette - I made an error on my first CDS vignette, and I'm trying to get a better grasp on this prior to my retake next month.
When calculating the plenum sizes, the largest joist and duct combo must be calculated for each floor independently, and in the instance of the 4.0 practice vignette, the joist and duct combo in the lab space is also calculated independently from the other two floors? So in total, you need to calculate the largest joist and duct combo for each of the 3 "floors"?
