Concrete core cooling CONCRETCOOL - Jacob-und-Wilhelm-Grimm-Zentrum, Humboldt University, Berlin

Unity of design

The new building, whose facades feature a travertine-like natural stone, has a formal austerity with a classical modern basis; its dynamism is underlined by the numerous rectangular windows in three different formats. The large storerooms are protected from daylight behind narrow slits, whereas the reading areas are illuminated through wider windows. The interior fittings are strictly oriented on the geometry of the facades. Walls, shelves and study tables are aligned with the building’s grid pattern. The tables are exactly the width of the spaces between the windows, and the sitting areas are precisely the width of the windows with clear vistas from all workplaces. In this way the interior fittings and the architecture of the building form a harmonious unit with full consciousness of its significance as a design element in the urban setting.

Function concrete core cooling CONCRETCOOL

In contrast to conventional systems, the supply air is not fed directly to the room, but first flows through aluminium cooling tubes embedded in the ceiling. The supply air cools the ceiling in the process. At the same time, the heat recovered is used to heat the supply air.

System advantages

  • Optimum thermal comfort
  • No additional ceiling cooling needed
  • Energy savings of up to 50% possible through free cooling
  • Full flexibility through modular distribution of cooling tubes
  • Cooling with outdoor air without use of recirculation air
  • Building cost reduction through low floor height
