• Overview
The market town of Rainbach is situated 720 meters above sea level in the north of the Province of Upper Austria. From the climatic point of view this region is characterized by its relatively high altitude above sea level and the frequency of defogged days.
The market town has about 3100 inhabitants. The structural weakness of the region also marks the financial situation of the market town.

The secondary modern school was opened in 1972 and shows good spatial qualities in its architectural concept. From the point of structural engineering it can be called an exemplarybuilding of the late 60s and the early 70s with high heating costs and structural-physical damages due to condensation waters.

CO2 – Konzentration in einer Schulklasse mit/ohne Lüftungsanlage
Co2 Messung – Before/ After Refurbishment
Zu heiß, zu trocken, zu stickig: So lautet das Ergebnis einer Studie zur Qualität der Raumluft in Österreichs Klassenzimmern. Eine deutliche Abnahme der Konzentrations- und Leistungsfähigkeit, Kopfschmerzen und schnellere Ermüdung können die Folge von schlechter Raumluft sein, erklärt Umwelthygieniker Hans-Peter Hutter von der Med-Uni Wien.

• History
The construction of the building, which is almost 5 decades old, is alright. The exterior walls which were built in 1957 were constructed out of poured concrete walls with a U-value of approximately 1,4 W/m²K. An insulation was later applied to parts of the cellar ceiling.
The exterior brickwork, the cellar ceiling, the ceiling of the attic, windows, doors etc. were not in accordance with the current state of the technics and were far from a forward-looking architecture.
The renovation will make the building capable of competing.

• Thermal skin
During the planning stage, the thermic skin was determined to avoid all possible weak points and thermal bridges. The project consisting of 50 old flats, was renovated into a passive house from the first floor on and the ground floor to a low energy house (Niedrigenergiehaus).

• Architecture outer skin – surveying
The high degree of pre-fabrication requires exact r eal measurement details. A conventional measurement would have been too imprec ise. The building was surveyed by 3D Laser Scanning. The 3D details were provided with X,Y, Z coordinates by the architecture office and transferred to the timber c onstruction company as 2D details for the element fabrication.
