A new study by tado° has found that the indoor temperatures of most European households are too high during summer. The study was conducted in 150,000 European homes from June – August 2019 between 12 – 6pm. It shows an overall average indoor temperature of 24.1ºC while an ideal temperature recommended by the World Health Organisation should be between 18º and 22ºC (depending on the room function) (1).
