4 Cases
Austria has a temperate continental climate, meaning cold winters and warm
summers with local differentiations due to altitude. The four schools featured in
the present study were built between 1961 and 1977, using similar mixed con-
structions methods and including concrete structures. The bearing columns of the
façades were in several cases outside the thermal envelope, creating serious
thermal bridges with the concrete slabs of the floors. Leaky doors, poor windows
and limited insulation contributed to low thermal performance.
The Austrian Institute for Building Technique [Österreichisches Institut für
Bautechnik, OIB (
http://www.oib.or.at
)] grants an energy certification [Ener-
giausweis] that gives the building a category with reference to its heat demand.
