A case study of the ventilation characteristics of office accommodation forming part of a recently refurbished building is presented. A mechanical system has been installed to ventilate and cool two floors that are interconnected by a series of atria, with a novel application of displacement ventilation applied where there is a very low ceiling height. The air distribution and air quality within the space have been studied by the application of computational fluid dynamics (cFD) to allow the computation of air change effectiveness in terms of local mean age. Variations in ventilation strategy have been explored and the results have been verified by perceived occupier satisfaction.
