260 - Fire safety in a carbon budget with Cecilia Wetterqvist and Axel Mossberg
A carbon budget can feel like a hard wall in modern building design, and once you treat CO2 as currency, everything starts competing for a slice of it. The problem is that fire safety systems often show up in those spreadsheets only as a penalty: extra embodied carbon for sprinklers, alarms, and protection. What gets ignored is the payoff. A serious fire can erase years of “sustainable” choices through demolition, replacement materials, repair labor, and lost building value, all with a very r…

259 - Communicating fire science with politicians with Birgitte Messerschmidt
Fire safety is a tough “product” to sell because the best outcome looks like nothing happened. That’s exactly why we sat down with Birgitte Messerschmidt (NFPA) to talk about communicating fire science to politicians, regulators, grant bodies, and other people in positions of power who can approve policies, permits, and funding, often with only a few minutes to spare. We share what changes when your audience is nontechnical, busy, and sometimes driven by incentives that do not neatly match engin

258 - e-mobility fires in trains with Adam Barowy
A battery fire on a train is not “just another small fire.” When a lithium-ion battery in an e-scooter or e-bike fails, the rail car can behave like a long pipe that moves smoke fast, limits escape options, and compresses decision-making into minutes. We sit down with Adam Barowy from UL Research Institutes FSRI to unpack new full-scale passenger rail car burn tests using real micro-mobility devices and realistic storage locations. We talk through what thermal runaway looks like before flames,

257 - Fire Fundamentals pt. 21 - Radiation with Simo Hostikka
In this episode of fire fundamentals we sit down with Professor Simo Hostikka from Aalto University to cover radiation in fires, both from the angle of physical phenomena and ways to model it. In this episode we cover following topics: feel less mysterious, from blackbody basics and role of radiation actually does inside the CFD N-S equation. Spectrum and emissivity to real engineering outcomes like heat flux, tenability Radiation’s two roles in fire CFD: target heat flux and the gas energy s
