With us this week is new friend, Kelly Alvarez Doran, via an introduction from Lloyd to talk about his experiences at COP28 and his carbon reduction consultancy Ha/f Climate Design that's challenged itself to reduce Canadian construction's emissions by half.We get sidetracked almost immediately while we talk about Kelly's background as an architect, working in mining, and the big changes to philosophy on building after working in Rwanda. In spite of the early diversion, we spent the whole conversation consistently hitting the same key themes themes:Embodied carbon and life cycle analysis Designing for the end of Oil-Age architectureRethinking the role of building design in the age of embodied carbon Kelly's great. He'll be back. Hopefully without any sound issues next time (it gets better after a bit).Also, XPS = Extruded polystyrene insulation.Notes from the showKelly on LinkedinConversations on the phasing out of oil felt paradoxical amidst the Dubai backdrop (The Architect's Newspaper, January 2024), Kelly's original view from COP28Embodied Embodied carbon values of common insulation materials (Canadian Architect, April 2021) i.e. the article with the chart that names brand names alongside embodied carbon values and egregious payback lead times for common insulation materialsThe YouTube video of the Straw Panel vs. Conventional Construction Burn Test that Kelly refers toThe Ha/f Climate Design websiteBuilding LCA for Architects Online Course (OneClick) a free primer course for architects by KellyThe UK Government Flood Risk Tool **SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**
