The architectural and engineering firm of Vollmer Associates, and electrical and mechanical specialists, Lakhani & Jordan Engineers, undertook this complex challenge by designing a modern air conditioning system in the historic Governor's Suite in New York's City Hall (NYCH). The architectural design needed to preserve the historic distinction of rooms and building, while installing state-of-the-art technology.
Located in downtown Manhattan, NYCH was built at a construction cost of $496,634 and was dedicated on July 4, 1811. In 1858, much of the upper stories and the cupola were destroyed in a fire touched off by a fireworks display that celebrated the completion of the Atlantic Cable. The building was restored two years later, and the façade was completely rebuilt from 1954 to 1956. It was declared a New York City landmark on February 1, 1966.
