The Cook County Administration and Chicago City Hall are both housed in a city block structure designed by the architectural firm of Holabird and Roche in the classical revival style and completed in 1911. The spacious high hallways are distinguished by impressive ceilings of flattened groin vaults and ornate Rococco style bronze lanterns over six feet tall in body length and weighing over 300 lbs. The matching wall sconces and flush mounted ceiling lights create a richly decorated family of fixtures appropriate for the classical style and dignity of the interior.
This project involved the restoration of the existing historic fixtures, replication from drawings and photos and some replication from the originals. In the upper floors, new corridor fixtures were chosen from SLALCO’S period custom design archives and engineered to achieve the IES light level recommendations for public spaces. The lamping for all of the corridor fixtures was energy efficient compact fluorescent with 20,000 hour lamp life.
