Building HVAC engineering (equipment sizing, ducting design, etc.) has been largely handwavy bullshit for a very long time and only recently has moved towards any sort of precision. Not uncommon to find boiler plants that are 3-4 times the maximum heating load in the winter, or fans running at 100% 24/7 when code only requires half of that.
Costs just get passed on to tenants so there was never much motivation to do better, the only reason building owners are moving now is because of government regulation and incentive programs.
Technology connections did a video on this, it's actually insane how much wastage there is
nice TC plug. One of my favorite channels and one of few reasons I use YouTube via new pipe and download the video. Let me also recommend Asianometery and Plainy Difficult.
