Summary

A strong component of climate change is an increase in average global temperature, leading to a rise in fire frequency. Research is mainly addressing wildland fire fuel, causing a lack of evidence regarding fires in urban areas. This study aims to reveal how structural materials influenced the destruction of the coastal areas in the Northeast region of Attica, in July 2018. Three thousand three hundred and four structures were spatially documented during the survey, while concomitantly registering their damage state and construction materials. The collected data was processed using Geographic Information Systems in concurrence with fire modelling to determine fire intensity. After completion, statistical methods and sensitivity analysis were conducted in order to assess the correlation between fire intensity and building damage state. Out of one thousand one hundred and forty four damaged structures, a large percentage were prefabricated buildings. Conversely, most structures implementing Eurocode standards did not suffer significant damage. Overall, the study confirmed that environmental factors determine fire magnitude to a great extent. However, implementation of non-flammable structural material could contribute to lower fire magnitude and a reduction in casualties.
