We are delighted to bring you a conversation with Professor Emeritus Susan Roaf, of Heriot-Watt University this week to talk about a bunch of fundamental problems in building design and the management of thermal comfort. She is a wonderful guest and we're looking forward to having her back.Originally, we planned to talk about her article COP 28: Net zero buildings by 2050? You have got to be joking! a well-judged critique of the outcomes at the most recent COP but we meandered a bit more than expected, but we still managed to cover most of the issues she raises.In the end, we took in a shared colonial history and its influence on the way we approach managing thermal comfort, problems with architectural education, the flaws in solely thinking about decarbonisation of the grid as a panacea, problems with designing buildings have an over-reliance on technology, as well as her colourful and storied background. In some ways with could be considered a counterpart to last year's episode about thermal comfort with Huda Elsherfif and Andy Simmonds, so check that too if you haven't heard it already.Notes from the showSusan on LinkedInHer article COP 28: Net zero buildings by 2050?
