These buildings were a complex of approximately 98,000 square feet.  The renovation was primarily mechanical and electrical in nature, and included a complete renovation of the City Hall lobby.  The HVAC system upgrade consisted of a conversion of the existing and dual temperature water system for each of the three buildings.  2RW designed a common chilled and heating  water loop with a 4-pipe primary secondary system and thermal ice storage.  Terminal units include fan-powered variable air volume (VAV) boxes with hot water coils, and fan coil units.  The constant volume central air handler was converted to VAV operation using a variable frequency heating system.  Complete direct digital controls (DDC) were added for all buildings.  New fire protection systems, fire alarm system and computer networking capabilities were added to City Hall and the Police Control Center.
