A solar chimney, or a solar thermal chimney, can be used to improve natural ventilation in buildings by encouraging the convection of air.
A simple vertical shaft designed to absorb solar heat will cause hot air to rise out of the top of a building - and draw cooler air into base of the building to generate natural stack ventilation.
Solar chimneys have been in use since the time of the Persians and the Romans.
A solar chimney is one of the techniques being used by Telford & Wrekin Council for the Wellington Town Redevelopment in Shropshire.
