"28c in the offices in a rich industrialized country? I wonder how much productivity they loose because of that."

A lot. The 28-degree "standard" has in fact been in place since 2005, when introduced by now-Tokyo governor Yuriko Koike who spent her younger years in Egypt, and has spread from government offices to almost the entire nation. In winter there is no corresponding artificially-low indoor temperature; if anything, they tend to keep it at 25-26 or more.

Total victory for the warm-blooded lizards and total misery for us hairy folk.
