Once indoors temperature hits 26, I can't get any work done. I know I have short temperature comfort range, but 30 indoors is crazy for me.

ido was talking about outside temperature.

I live in one of the hottest cities in Germany (Karlsruhe) and I agree with ido. There's around 2-3 weeks where home air conditioning would really be useful. The rest of the time, temperature is controlled easily enough by opening windows at night and closing the shutters during the daytime while at the office.

Air conditioning for offices is a different story.

I don't think indoor temperature ever reached 30c inside my apartment (or if it did it was definitely not for long).
