Passive house school in Brixlegg
Renovation and extension to passive house standard
Planning: Architekturbüro DI Raimund Rainer
The school in Brixlegg (Tyrol, Austria) was completed in February 2007 in passive house construction. Comfort, sustainability, energy savings and climate protection combined with costs as the priorities of renovation. Likewise town planning played a role: the new square structure joins the school yard, grades 5-9 and kindergarten. The school was organized in four levels and encloses a covered entrance.
A highly insulated building shell with passive house windows (with automatic exterior shading) and a central ventilation system with heat recovery establish the prerequisites for the passive house standard (heating requirement less than 15 kWh/m²a). The school was also build with handicapped access (an elevator joins all the levels).
