This Japanese House Never gets Hot, Why Did the Energy Industry Bury it?

How did a 200-year-old Japanese wooden house stay cool without AC? 🏯 In this video, we explore the genius of the machiya - traditional Japanese townhouses that used airflow, shade, courtyards, skylights, and even water rituals to beat extreme summer heat. It’s a fascinating look at passive cooling, timeless architecture, and why modern buildings still ignore solutions that worked centuries ago.
