Passive House Design in Austria

"Schiestlhaus": this building is the first “alpine passive house”, meaning in this case that it produces its own energy from solar sources.

“Passive houses” in general are buildings with an excellent thermal insulation quality, and are equipped with a ventilation system that is able to re-extract thermal energy from the discharged air. Therefore theses buildings work without a conventional heating system, as they take their heat energy from inhabitants (about 70W per person!), solar radiation and a minimal backup system for long cold periods in wintertime.
