The document discusses the installation of natural ventilation systems at Ashmount SEN School in Loughborough by Airtherm Engineering. Airtherm designed and selected the correct systems for the school hall in consultation with Derry Building Services and Leicester Council. The systems were installed successfully in line with CIBSE guidelines. Airtherm's Wind-iVent natural ventilation terminals operate using aerodynamic principles to draw in fresh air and expel stale air through the use of positive and negative pressure areas around the terminal.
