The key point I'm trying to make is that the shade structure or outer shell should be separated by at least 50cm, and in such a way that even the slightest breeze moves air though it.
Yeah I think that’s done. Tragically this technique coupled with a poor selection of materials was the structural cause of the grenfell fire. We see this kind of panelling around various European cities. “Cladding” it is called and it serves a few different purposes with regards to thermal management.
