Controlled natural ventilation reduces the risk of infection by aerosols. Fresh air also boosts one’s ability to concentrate and creates a safe learning atmosphere. When windows are open wide, fresh air from outside displaces the stale air and effectively dissipates aerosols. An automated ventilation solution from D+H provides fresh air within freely configurable time intervals (beginning, duration), or when a defined CO2 value has been exceeded. If necessary, window opening can be activated manually at any time. This means that this D+H solution complies with the most important recommendations from the German Ministries of Education and the Environment.
