“Because green skyscrapers and high-rises are a bullshit non-solution to serious systemic problems.”
“But if you want greenery on a building nonetheless, do I have an idea for you – a portable, modular, scalable solution called ‘potted plants on your balcony’.”
Legionnaires’ disease
Exactly.
And hospitals had to solve the problem which is a system many buildings nowadays use (a bit depending on local climate needs). We now have osmosis water filtration for the humidifier (like 10+ kW for colder winter months?), HEPA filters before and after, mechanical & screen filters for the inlets (for potential smog particles, pollen, paragliders, that soft or thing) and probably much more stuff (various sensors, noise traps, regulators, fans, …). All components have their own maintenance needs.
But if we were to cheap out and not hire actual professionals that are good at their jobs … believe it or not, we all turn into an army of legionnaires and storm the city. And since we are in Europe, I mean highly organized Roman legionnaires.
