Why We Need Passivhaus in Hot Climates - It's not just for the temperate north.

This article was published in June 2022 by Lloyd Alter on Treehugger.

One of the many myths about the Passive House or Passivhaus standard of building is it was designed for temperate Germany and is not really suitable for really cold or hot climates. The Passivhaus concept is a particularly tough sell in hot climates, especially in places with big diurnal swings in temperature, where one would traditionally design houses with thick walls for thermal inertia and natural ventilation at night, and nobody thinks much about insulation. But what once worked in the desert doesn't anymore.
