> This, by the way, supports an entire ecosystem of builders, architects, and suppliers who must keep up with the times and are constantly exploring new innovations in house-building. Just add the real: Houses aren't good unless you manually choose better one. Known one is that Japanese insulation standards are still quite bad. Aluminum single glass window is still allowed to use for new building. It's horrible to use a material for insulation that used for heat sinks. This is partially due to the window manufacturer is also a big aluminum manufacturer.
