Abstract:
Architects' decisions related to fire considerations are in some cases cost-driven. Such constraints limit fire safety options to a minimum of code compliance at a late stage in the design. The research hypothesises that the improper consideration of fire safety in the architectural design of retail buildings could be due to lack of basic fire safety engineering knowledge in the architectural education, and/or project budget limitations. One step towards better understanding of fire safety issues is to translate the physical knowledge into architectural terms. This research aims to develop architectural guidelines for an early integration of natural smoke ventilation (NSV). Such guidelines are intended to allow architects to think "safe", and guide them towards a truly integrated fire safety design within the design process. The proposed theme provides an insight of the differences in design priorities for early integration of natural building and smoke ventilation among architects, fire engineers and building services engineers. Assessing the differences in design priorities allowed identifying the gap of fire safety knowledge in the architectural education. The assessment process was carried out using the Analytic Hierarchy Process (AHP) approach in surveying engineers and architects. Architects' results showed that academics and practitioners have different perceptions. Engineers' results provided a prioritized scheme for the design decisions with respect to the criticality of early integration of NSV objectives. To confirm the criticality of decisions' priorities, Computational Fluid Dynamics (CFD) modelling using Fire Dynamics Simulator (FDS) was carried out to emphasize the imperativeness for early integration of one of the most crucial design decisions. Results from FDS showed that the horizontal profile of atrium has a considerable impact on the performance of natural smoke ventilation. The research results are in good agreement with the first research hypothesis that lack of fire safety knowledge in the Architecture education results in later consideration of fire safety objectives in the design. However, the results refute the second hypothesis that the budget always governs the decision of the early integration, especially in large retail buildings.
