Uh, quite the opposite. Thermal mass is a thing. How houses are built in Iceland: https://youtu.be/7RuTizbnH4s?si=JxRjqzVFy4NLg3wa https://youtu.be/7RuTizbnH4s

  "Thermal mass" and thick concrete isn't what keeps that house at a comfortable temperature from summer to winter. It's comfortable for the same reason as any other house: because it has thick insulation both outside and inside the concrete. See @4:30 in your linked video.[0] If you like, sit down and do the math for how thick concrete you'd need in order to store heat for 6+ months and average out the summer/winter temperature change. It's not 1 foot thick, it's more like 30 feet thick!! In general, the effect of thermal mass tends to be strongly overrated by people who aren't experts in building science.[1] [0] https://www.youtube.com/watch?v=7RuTizbnH4s&t=270 https://www.youtube.com/watch?v=7RuTizbnH4s&t=270 [1] https://web.archive.org/web/20130509032945/http://www.greenbuildingadvisor.com/blogs/dept/musings/all-about-thermal-mass https://web.archive.org/web/20130509032945/http://www.greenb...
