Clean air means a clear mind

Classrooms need regular ventilation.

Remember the following tips:

  • If you need to ventilate a room during the cold season, open the windows wide for a short period of time rather than leaving a window slightly ajar for long periods of time, which leads to significant heat loss.
  • Cleaning windows regularly will make the classroom brighter and cosier, and you will need less artificial light.
