A practical application of computer modelling to a building atrium.

Computer modelling is becoming an everyday tool for the building services engineer to ensure that a ventilation design will work early on in the development process. This paper describes this process in relation to Novartis' new office building in the UK. In this case, airflow modelling was used to fine-tune a conceptual idea for the atrium air conditioning. This influenced the solar shading incorporated into the architectural design and allowed engineers to optimise the volume of air used and the location of supply air terminals. Ultimately, this produced the most energy efficient and comfortable design that was then taken through the detailed design and installed within the building.
