Massachusetts Historical Society

Boston, MA


The Massachusetts Historical Society building is a landmark in the city of Boston, and holds some of the state’s most valuable artifacts. Our goal was to provide precise temperature and humidity control to all artifact storage areas, while providing general comfort to the surrounding support areas. All work had to be performed while the facility remained open to the public. The building consisted of six floors and a basement with a mechanical room.


HVAC system is a 4-pipe fan coil unit system, although it was operated as a 2-pipe system with seasonal changeover, until completion of the final phase allowed for switchover to 4-pipe operation. Major equipment included two chillers with remote roof-mounted condensing units, air handling units with HW / ChW conditioning, and 4-pipe fan coil units. Controls were comprised of a blend of pneumatic and DDC devices.
