The first version of this "Atlas" contains over 100 cases of office air flow patterns for different ventilation systems. The book is designed to give the design engineer a quick idea of how a particular system works under various loads. Maps have been prepared for velocity, temperature, turbulent kinetic energy, percentage dissatisfied due to draft risk, and pollutant concentrations (caused by a smoker, bookshelf, or by building materials).
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.
This paper reports the results of humidity and ventilation measurements in occupied residential buildings to study the effect of airborne moisture movement on condensation risks. The dwellings have been fitted with a cooker hood and an extractor fan (both with variable speed control) in the kitchen and an extractor fan in the bathroom.
