An important goal in the S-HOUSE project was to combine ecological and functional advantages and to reduce energy and resource consumption by a factor of 10 through the consistent use of renewable raw materials.

Eckdaten

Ort:Böheimkirchen Fertigstellung:2005 Bauweise:straw bale wrapping Entwurf & Planung:Arch. Scheicher Zimmerer:Zimmerei Hager, GrAT Besichtigung:Nein Pressebilder:Nein
Eigenleistung:Straw bale infill, clay plaster under the façade Mängel:A very consistent but also relatively expensive building. But this model building is primarily intended to show possibilities for the future, and it does so consistently.
Wohnnutzfläche:240m2 Heizwärbebedarf:5 U-Wert (Wand):0,08W/m2K U-Wert (Dach):0,08W/m2K Haustechnik:The components of the building services were selected according to efficiency and recyclability, and pipe lengths were minimised and mineral or fossil raw materials were replaced by renewable raw materials to the greatest possible extent. The ventilation ducts and cable routes are made of wood. Special stone pine interior surfaces in the fresh air ducts improve the indoor climate and increase the well-being of the users. The green roof stores rainwater and delays runoff during heavy rainfall.

Straw-bale passive house, a House of the Future project by GrAT (Group for Adapted Technology at the Vienna University of Technology). An important goal in the S-HOUSE project was to combine ecological and functional advantages and to reduce energy and resource consumption by a factor of 10 through the consistent use of renewable raw materials. The comparison using ecological evaluation methods of a straw wall construction with a conventional wall construction has shown that the straw wall performs better in all calculation criteria by up to a factor of 10. While the production of the straw wall causes an ecological footprint of only 2364 (m²a/m² wall), the comparable conventional wall construction with 24915 (m²a/m² wall) consumes more than 10 times as much natural land.

Strohballen-Passivhaus, ein Haus der Zukunft-Projekt der GrAT (Gruppe Angepasste Technologie an der TU Wien). Ein wichtiges Ziel im S-HOUSE Projekt war es, ökologische und funktionelle Vorteile zu verbinden und durch den konsequenten Einsatz von nachwachsenden Rohstoffen den Energie- und Ressourcenverbrauch um den Faktor 10 zu senken. Der Vergleich mit Hilfe von ökologischen Bewertungsmethoden einer Strohwandkonstruktion mit einem konventionellen Wandaufbau hat gezeigt, dass die Strohwand in allen Berechnungskriterien um bis zum Faktor 10 besser abschneidet. Während die Herstellung der Strohwand einen ökologischen Fußabdruck von nur 2364 (m²a/m² Wand) verursacht, verbraucht der vergleichbare konventionelle Wandaufbau mit 24915 (m²a/m² Wand) mehr als 10 Mal soviel natürliche Flächen.
