Thermal stratification in atria

Atria are now a standard feature of shopping centres and commercial buildings. Yet little is known about the thermal performance of large glazed spaces, where factors such as the level of thermal stratification and the maximum temperatures which can occur are important. This thesis provides case study monitoring results of a two storey atrium, where the thermal stratification in the atrium and outside weather conditions were measured with respect to time. Also presented is a model to predict the thermal performance of atria by utilising an existing building energy simulation program and the theory of natural ventilation in enclosures.
