I think anyone who’s ever worked in construction would balk at the idea of hanging your life on pieces of building facade. Except for the the pieces stopping people falling through the outside windows and walls themselves, most of the outside decorative stuff is only designed to hold itself onto the building and not much more. He’s potentially hanging his 200lbs on something that’s intended to hold 0lbs.

No, you forgot that architects count the wind forces in, not just the weight of pieces hanging onto the facade. Give them dynamic spikes of factor 10, so it looks more like 1000lbs. Only once you can get your engineers to agree on only factor 2, you can build much much lighter structures.

No I didn’t, you’re talking about big sheets of stuff, which probably won’t have anything to hold onto on it. I’m talking about the fiddly little bits that he’s likely to be holding onto. A little bit of flashing around a window has a wind load approaching zero.

When I'm cleaning highrise windows I put a looot of force crimping window frames to move laterally. I haven't broken anything yet.

I've also done a facade inspection on a building where massive sheets of metal had been badly installed. The vast majority of them weren't connected to the structural steel beams, they were just held together by single screws (with no nuts!) that were falling off due to wind making the screws bore a bigger hole. A sheet had fallen off the 12th floor right onto the busy boulevard below.
