What’s a passive house?

  Simply said, a house with no or very limited heating system. But it is of course more complicated than that. https://en.wikipedia.org/wiki/Passive_house#Space_heating_requirement https://en.wikipedia.org/wiki/Passive_house#Space_heating_re...

  As far as I can tell, it's a standard which just means that the building needs very little energy for heating or cooling. It mostly comes down to making the building very insulated (as far as I can tell--not saying that's the complete story, but that's a big factor). https://en.wikipedia.org/wiki/Passive_house https://en.wikipedia.org/wiki/Passive_house

  Passive house atleast here means a house that generates more energy then it consumes. E.g very well insulated house with solar power, ventilation that gives back energy etc.

  They are designed to reduce energy requirements (especially heating and cooling) by at least 75% to 90% compared to regular homes and ideally by 100% by capturing and holding heat in the winter and blocking heat in the summer. They tend to have thick walls, triple paned windows, and be air tight. https://passipedia.org/basics/what_is_a_passive_house https://passipedia.org/basics/what_is_a_passive_house
