Someone put up a tent on their balcony to escape their heat-trapping apartment during the night. (discuss.tchncs.de)

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.

Apartment with external shutters can still overheat if situated in a strong urban heat island and heatwave endures for long time...

    Yeah but it tells of a better efficiency

    No, this type of external shutters is standard for German homes, so tells not much by itself.
    As for the efficiency: Buildings here are mainly designed for colder weather, with the intent to keep the warmth inside and at a constant temperature (thick, massive walls and insulation on the outside). And at this, they are very efficient.
    But during the recent, unusually long heat waves, once the heat managed to seep in (typically after 3-4 days), you are basically screwed, as you have no chance to lower the inside temperature without AC.
    Temperature stays high even at night, trapped in the walls.
