Novel Natural ventilation in a multiple storey office building: The UCL SSEES Building, Bloomsbury, London

We describe the results of simple modelling and some laboratory experiments of the natural ventilation flows which can develop in an office building when air is supplied from a central atrium, passes through the floor-space of the building, and then vents through stacks at the perimeter of the building. We explore the flow in summer when pre-cooled air is supplied at the top of the atrium, in spring-autumn, when pre-cooling may not be required, and in winter when air is supplied from the base of the atrium, illustrating how such a dynamic design can extend the seasonal window for which natural ventilation is effective.
