Why can’t airports just be standard or double maybe triple height, why do they have to be so big?

In the airport where I work, the public areas are all tall ceilings 40 to 60 foot. I see lots of posts talking about baggage, etc. At my airport at least, that’s all underground… As far down as the ceilings are high. We have several sublevels, including a dedicated level just for baggage handling, and another just for utilities, etc.

I would think it has to do with keeping a stable climate during surges and lulls of people. Similar to how it’s easier to maintain water quality in a large aquarium s a smaller tank, more air volume will remain a steady temperature/quality.

I have nothing to back this up. Just a hunch.

Clearly you haven’t been to Washington Dulles C terminal. [https://commons.wikimedia.org/wiki/File:Inside_Concourse_C.jpg](https://commons.wikimedia.org/wiki/File:Inside_Concourse_C.jpg)

Granted the main terminal has a huge soaring roofline, but the C building is the opposite with lower normal height ceilings.

Some have low ceilings in areas, especially if I remember DFW correctly from a few years back. It is claustrophobic and super loud/hot. High ceilings are good for sound, temperature, and general feel.
