“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’.”
Except that plants grow… and grow, and grow. Unless they’re maintained, which takes additional labor and people and infrastructure to handle, all of which adds even more weight.
As said, you don’t need to use trees or gigantic plants, use Twiners and shrubs, they cover the whole facade and don’t way that much, yet they do the same, if not a better job at keeping the building cool and the air cleaner. They don’t need much maintenance and they don’t grow indefinitely, if the plant cant reach more facade it stops, only thing is you have to regularly cut the plants around the windows, wich isn’t a gigantic problem.
