This month the cost arid research departments of Mott Green Wdll and Davis Langdon & Everest examine the costs and specification of chilled ceilings and beams in collaboration with specialists Trox and Halton.
A simple multi-layer stratification model is suggested for displacement ventilation in a single-zone building driven by a heat source distributed uniformly over a vertical wall. Theoretical expressions are obtained for the stratification interface height and ventilation flow rate and compared with those obtained by an existing model available in the literature. Experiments were also carried out using a recently developed fine-bubble modelling technique.
Computational Fluid Dynamic (CFD) has rapidly developed as an industrial design and evaluation tool for Building Services Engineering. Providing valuable information via mathematical predictions of fluid flow heat and mass transfer. The aim of the work is to illustrate the integration of CFD data into a truly interactive Virtual Reality (VR) environment to provide engineers with demonstrable design evaluation and visualisation facilities. To demonstrate the successful integration of CFD and VR an industrial case study of a conference room at Hoare Lea is presented.
The objective of this project was to provide cool working conditions for a small number of Customs Department staff in a turn-of-the-century heritage building in Town ville at 19° S latitude. A ducted air conditioning system was initially proposed but rejected as it would have been incongruent with the Victorian elegance of the space, as well as its high cost. As the working area in the three storey high space was surrounded by ornate timber counter and partitions, a scheme was developed using fan coil direct expansion units. These were located behind the counter to the public space.
