Discarding system losses, an elevator without counterweight will also use 0 energy for the up/down cycle (assuming load goes up and some time later down): the energy invested while pulling up the system can be recovered when descending.

ThyssenKrupp comes and repairs it every now and then. They are simple elevators. The reliability I can imagine from my experience with TK elevators I think the floors will be a better option. Once I was working for a TK company, and the TK elevator broke down. It was not repaired by the sibling company for a whole month because of some component shortage... That was a simple elevator in a 5 storey building.
