From 1991 - 1993 this building has been retrofitted as a representative example for this type of school, in order to show the energy saving potentials. One of the main retrofit features was the use and assessment of transparent insulation in comparison to the use of standard insulation material. Retrofit features: Transparent insulation. Insulation of walls, roof and cellar ceiling, low-E-coated windows. Sun-shading in front of the transparent insulation and the south-oriented windows (after over-heating in    the first season). New heating control system, individual room control. Ventilation slots in the window frames and supplying fans.   total report as pdf-download in English   © 2004 Fraunhofer Institute for Building Physics
