The Nucleus Hospital programme has been progressed by the Department of Health for over a decade. The Maidstone District General Hospital was the first project which involved the construction of a complete hospital using the Nucleus design concept. Within a hospital, air movement patterns and air change rates are a prime concern in the case of Maidstone, the interest in these parameters was much greater in view of the fact that a natural ventilation strategy had been chosen for ward units.
In designing air-conditioning systems for large-scale indoor spaces, it is important to predict the air velocity and temperature distributions in such spaces to enable indoor climate to be controlled effectively. The indoor climate can be predicted by two numerical simulation methods: one is a rough study by using a macroscopic model and the other is numerical simulation based on a turbulence model. Each method has its own limitations.
