Project Benefits to County

• Allows necessary facility improvements and repairs to

be made without using capital or maintenance budgets.

• 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

EMS Installation

Building Technologies

1. Determine desired project scope

2. Contact Grid Account Manager/Solutions Representative

3. Explain process to client – contract is with the client

4. Understand programs available (evolving)

5. Determine projects that can be funded and complete applications

– Custom measures

– Prescriptive measures

6. Pre-project installation survey

7. Technical review of application

8. Pre-Approval letter from National Grid

9. Implementation of project

10. Post-installation verification

11. Client gets paid
