• Guaranteed performance with Siemens accountable for results.
• Reduce expenditures for utility, technology, service and operations.
• Provide life-cycle cost solutions and technology improvements.
Building Technologies
Rensselaer County Office Building
Building Technologies
• Five story building, about 80,000 sq.ft.
• Originally constructed as a school
• Home to 26 County Departments
• Perimeter baseboard heating via 2 aged sectional boilers
• Cooling via a 30 ton RTU, AHU, and Liebert for data center
• No existing EMS
– RTU cycled on/off manually
– AHU supply fan had catastrophically failed – RAF used to supply air
– Chiller for AHU controlled by manually altering the chilled water supply T
– No zone valves for heating – manually controlled
