Rensselaer County Office Building Infrastructure Upgrade Utilizing National Grid Incentives

Rensselaer County is enhancing its office building with improvements funded by National Grid incentives. The facility, originally a school, is a five-story structure housing 26 county departments. Key upgrades include the installation of a new Energy Management System, demand control ventilation, and replacement of outdated heating and cooling systems. These enhancements aim to improve energy efficiency, reduce operational costs, and allow necessary repairs without impacting capital and maintenance budgets, benefiting the county and its departments significantly.

  5. Pre-Existing Building Conditions • 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

  7. Facility Improvement Measures • Energy Management System Installation • Demand Control Ventilation • Replace 30 – Ton Rooftop Unit • Hot Water Reset Controls • Replace Electric Domestic Hot Water Heater with a Natural Gas Fired Unit • Replace Space heating Boilers with Condensing Units • Upgrade Lighting • Weatherization Improvements • Replace Emergency Generator

  8. EMS Installation • Apogee System Installed • Two workstations • Boiler room components • Main AHU, Chiller and Cooling Tower • RTU • Scheduling • Demand Control Ventilation • Heating zone valves and sensors • VFD on Main AHU Return and Supply Fans • Hot Water Reset Controls • Filter pressure sensors and alarms • Retro-comissioned face and bypass dampers – provided for “free cooling”

  9. Steps in Obtaining National Grid Incentives • Determine desired project scope • Contact Grid Account Manager/Solutions Representative • Explain process to client – contract is with the client • Understand programs available (evolving) • Determine projects that can be funded and complete applications • Custom measures • Prescriptive measures • Pre-project installation survey • Technical review of application • Pre-Approval letter from National Grid • Implementation of project • Post-installation verification • Client gets paid

  10. National Grid Incentives Prescriptive Measures • Boiler replacement $30,000 • Lighting upgrades $57,785 Custom Electric Incentives 1. DDC Controls $32,850 2.
