Yes, according to the Guinness Book of World Records, this PassivDom modulOne is the “warmest house in the world.”
And it’s only 380 sq. ft.! The modulOne is a super cool manufactured structure that comes in three “levels” of completeness: The Autonomous (which is 100% self-sustaining), the Standard (which has all your appliances, fixtures, etc. but needs to be hooked up to exterior power/sewer), and the Module Plus (a finished shell with wiring for electrical and heating, but nothing else).
