Ever wondered if your heating or air conditioning in your house is really necessary? Passive House (Passivhaus) is a design approach to buildings that reduce the energy required drastically. This video explains briefly in 90 seconds how it's done.
About me (yes, I made this video, that's my hand you see and my silly voice you hear): I'm a Certified Passive House Fan (Certified Passive House Consultant). I'm involved in this great movement to create highly energy efficient buildings that use 80 to 90% less energy. But how? I get asked often what a Passive House is. This is the explanation in 90 seconds.
