Energetic renovation of the facade of a research building

In 1994 a laboratory building was erected on the campus of the max Planck institute for psychiatry in Munich-Schwabing as a 4-storey reinforced concrete building with a perforated facade made of a thermal insulation composite system. The rainwater drainage of the barrel-shaped technical roof center was designed as an "internal" aluminum box gutter with a cross-section of only 80 mm.

The thermal insulation composite system with 10 cm thick polystyrene insulation and thin plaster showed considerable damage in the form of behind-the-scenes insulation and large-scale plaster flaking. The facade renovation planned by Kai Otto Architekten was carried out after demolition of the existing composite thermal insulation facade with installation of a composite thermal insulation system consisting of mineral wool insulation in accordance with the applicable EnEV and thick plaster. In addition, the existing drop arm awnings for the external sun protection system were removed, serviced, defective components were repaired and fitted with new hangings. The canopy of the goods receiving area located on the first floor was renewed and connected to the courtyard drainage system. The clinic building received a new external staircase as a 2nd escape route.
