Displacement ventilation is a method that provides conditioned air to indoor environments with the view to improve air quality whilst reducing energy usage. These systems have been employed in industrial applications, notably in Scandinavia, for many years and have gained in popularity in office building spaces in recent years. Measurements of velocity and temperature fields have been performed in three modern office spaces to analyse the performance of the incorporated displacement ventilation system0>, based on thermal comfort and temperature gradient assessment<2>.
