Someone put up a tent on their balcony to escape their heat-trapping apartment during the night.

Third extended heat wave within 6 weeks.
The previous one exceeded 40°C, and the buildings not yet had time to completely cool down from that one before the third wave hit.
I was considering putting up a tent in my garden myself, but as I own a ground floor flat, the indoor temperatures did, with the help of some additional cooling measures, thankfully not exceeded 27°C.
.
Not that I didn't try the fan solution. Done properly, I managed to reduce the air temperature by about 1°C by early morning compared to the evening.
Still not enough in some cases. My bedroom for example. It's on the southside of the building and even with every window open and fans running till late in the night, I can still feel the temperature difference between north and south side rooms.
Skill issue
Open windows make it so much worse if the air is very hot and/or there is no wind - which is often the case in many places
Said that, i syill keep them open because i got one of those fans that cool air using water which makes a lot of humidity that somehow i need to remove
Telling a German to open windows is like telling a bird how to fly. Stoßlüften is down to a precise science here.
But it doesn’t matter with the temperatures and building construction style. They retain heat like crazy. It’s not getting cold enough at night for the buildings to lose all their thermal energy, even creating air flow through the building with a fan. Source: me with all my windows open in a 4th floor apartment with the inside temperature sitting at 28°C at near midnight.
You mean, not everyone in the world is using a multiple-wireless-thermometer and -hygrometer arrangement to determine the exact optimal millisecond to switch from one complex apartment window configuration to the next?
As a German, I am really confused by that idea... ;-)
