Interesting how much emphasis is put on ventilation. I guess the soporific effects of stale air were well-known in 1883, though they didn’t have CO2 monitors of course :)
Also maybe they knew things about cooling buildings without AC that we have forgotten.
An interesting quirk of old buildings is a structure called a "transom" - a space above a door which could be opened to allow for the free flow of air. Regrettably, it also allowed for highly effective oxygenation of fire, resulting in countless deaths, and so has been excised from the architectural lexicon.
