Investigating thermal conditions in a tropic atrium employing CFD and DTM techniques

Focusing on the ‘worst-case scenario’, a modelling study was carried out to examine whether a low cost ventilation solution could provide basic comfort in a specific atrium-building design. This study combined dynamic thermal modelling (DTM) and computational fluid dynamics (CFD) in investigating...
