In the context of growing awareness of the implications of global warming and the rising fuel cost, reducing energy consumption in the building sector, which account for significant proportion of total energy consumption and the subsequent C02 emission, holds considerable potential in confronting the problems at hand and in the near future. Natural ventilation is a passive means of ventilating buildings via utilisation of natural forces that can reduce the energy consumption from air-conditioning systems, a common feature in modern non- domestic buildings, which account for almost half of the energy consumption in buildings. With surge of interest in the advanced natural ventilation system and stack ventilation in recent years, numerous buildings have demonstrated feasibility of maximising natural ventilation system in an urban environment. This dissertation addresses the theories behind the design of naturally ventilated buildings to form a basis for understanding complicated advanced natural ventilation systems. Moreover, the design of advanced natural ventilation system in five buildings - Heelis, National Assembly for Wales, School of Slavonic and East European Studies, Lanchester Library and Harm A. Weber Library - are analysed in detail, to present information on the exemplar cases of advanced naturally ventilated buildings, together with the operational performance to evaluate the design based on the extent to which it reduces the energy consumption. The key findings from case studies and the overview include extensive use of simulation tools which lead to introduction of various innovative design elements that propose overcoming the limitations confronted by the precedent naturally ventilated buildings. In addition, the analysis of operational performance of the buildings revealed relatively stable internal conditions in comparison to the significant difference between the estimated and post occupancy energy consumption. Moreover, a proposition has been made to expand the taxonomy for advanced naturally ...
