Tweed Courthouse


Beginning in 1861 and constructed over the course of twenty years, the Tweed Courthouse occupies a unique place in New York city’s history. An ambitious, $85 million restoration project begun in 1999 aimed to prepare the courthouse for the new century while altering neither the building’s interior or exterior. Contracted to update the exceedingly antiquated heating and cooling systems, TEC installed a Honeywell EXCEL 5000 product line inside the building’s original ventilation shafts. Featuring 12 air-handling units, carbon-monoxide monitoring, and more, the system brings this landmark 21st-century longevity while simultaneously preserving its 19th-century tradition.
