Worst thing is that housing in Europe, outside of Southern Europe, is not geared (unless it is brand new) for such high temperatures during the summer at all. Most places do not have air conditioning either.
Even most metros do not have any type of air conditioning which is frankly a disgrace. Let alone trains and other public transportation.
In Arabia and in the Arab world in general, before the era of modern air condition etc., windcatchers, courtyards, mashrabiya screens, building materials with high thermal mass such as stone and stone houses, mud bricks, coral stone, granite, sandstone etc. were used and served their purpose very well. To this day people living in such housing can do without air conditioning.
Nowadays you have air condition almost everywhere (even bus stops outside) during the 3-4 hottest months (summer) during the year.
Similar to how traditional houses and housing was constructed in South Europe. Albeit slightly different materials were used.
I remember once staying in Spain on holidays in a traditional hacienda (stone house) and it was perfectly fine without air condoning even during high temperatures or in the middle of the day.
