The Bertolt-Brecht-School represents one of the so-called "typical schools" built with a
prefabricated modular concept (Plattenbauweise) in the former German Democratic Republic in the 1960's and 70's. The heating energy consumption
of the school was very high before the retrofit because of no insulation, poor window quality and poor airtightness. The energetic retrofit
included the transformation of the courtyards into two atria. Thus they can be used as common rooms such as canteen and auditorium. The aim
was to show the energy saving potential and the possible improvement of the school's social facilities.
Retrofit features:
Transformation of courtyards into atria.
Pre-heating of the air through atria in winter and night ventilation in summer.
Insulation of exterior walls with 12 cm styrofoam and plaster (composite thermal insulation system).
Insulation of the roof, low-E coated glazing in wooden frames.
New control of heating system (night+weekend set-back), daylight-dependent artificial lighting control.
