Cork County Hall

  • Refurbishment and extension for Cork County Council.
  • Ireland’s tallest building when constructed in 1967.
  • 24% reduction in energy cost over comparable modern office buildings with a corresponding 42% reduction in carbon emissions.

Cork County Hall, the administrative headquarters for Cork County Council, was extended and refurbished to provide 15,000m² of accommodation. 

The existing tower was re-clad with an active glazed louvre façade that responds to the local climate, ensuring optimum environmental conditions. 

Above the lower ground floor library, the development consists of a 2 storey ancillary building joined to the main 6 storey building plus a landscaped plaza area surrounding the sunken courtyards. The 2 storey building features a 4.5m cantilever meeting room, while the 6 storey block features a double height space at the rear of the building to allow the mobile library to load and unload books.

Energy gains

The building is naturally ventilated except for its fully air conditioned egg shaped copper clad council chamber. An active louvre façade replaced the existing precast concrete cladding. This façade responds to the local climate, ensuring optimal environmental conditions at minimum energy costs. Arup was responsible for securing a €500,000 grant from Sustainable Energy Authority Ireland towards the cost of the louvre system.

The building was also provided with state of the art high frequency lighting technology, fully automatic lighting control responding to occupant’s presence and day-lighting levels.
