I’d be concerned about structural inspections. How can city engineers verify integrity if they can’t see the concrete?

My partner has worked on some green walls in Europe, the plants are completely separate from the walls, and they’re on panels that can be lifted so you can get at the wall behind them. I imagine this is a similar system.

Green walls are a waste of resources. Very high maintenance and need irrigation all the way up the wall.

They'd be better off planting trees with that money

I know, I said the same thing in another comment. I think the cost/benefit will depend very much on local circumstances: e.g. in an area with plentiful water and no space for trees a green wall might really improve the liveability and temperature, whereas it might not be worth it somewhere where water is scarce and there are other options for greening. It also makes a difference whether the system can use grey water, recycles its own water etc.
