In today's episode, I have invited dr Eleni Asimakopoulou from the University of Central Lancashire to discuss her extensive expertise on fire behaviour of facades. In the talk, we will go through Elenis' experiments on ventilated facades (and clear out what they are and why we use them). We do discuss the complexities of testing facade systems. We traverse through the global testing landscape, comparing diverse methods ranging from the German DIN4102 to its American NFPA counterpart. We discuss the role of air entrainment related to test geometries, the implications of whether there's an opening, and the potential effects of a fire barrier in proximity to the fire load.  Our discussion takes a heated turn as we broach large-scale fire testing and modelling. We go into how tiny details can dramatically impact a facade system's performance and whether we will be able to reliably capture that with large-scale tests, small tests or modelling. We'll also discuss the future - machine learning, CFD, and finite element analysis which are revolutionizing fire testing. Lastly, we delve into the newest research and developments in facades, discussing the advent of tools for material properties analysis, and more.  Here is the link to the paper discussed in the episode: https://www.scopus.com/record/display.uri?eid=2-s2.0-85085977558
