Case Study: Nassau County Department of Public Works Hicksville Garage HVAC Renovation

HVAC Case Study

This project was a team effort between ATI, a local contracting service, and Nassau County personnel. The County’s lead engineer on the project was Adrian Cavanagh P.E.

The Project

The Nassau County Department of Public Works needed a complete upgrade to their boiler equipment. This included replacement of existing:

  • Boilers
  • Burners
  • Fuel oil pump set
  • Lead/lag panel
  • Pumps
  • Expansion tank
  • Air separator

For a job of this size and complexity, the experts at ATI were the natural choice to develop a solution that met the facility’s needs and kept the department’s fiscal responsibility to the taxpayers of Nassau County in mind. ATI has a proven track record of working with municipalities, counties, and other governmental agencies.

The Challenge

The primary challenge (aside from equipment replacement needs) was the lack of accessibility to the equipment area. There was no elevator access, and no direct access to the equipment room from outside.  

The doors at the end of a stairway provided the only access to the equipment area:

Additionally, the new equipment would need to be reconfigured. The existing layout made space limited and servicing difficult:

The Solution

ATI devised an ideal total solution in a boiler and pump package uniquely addressing each of the challenges presented.

The new equipment package consisted of:

The equipment was transported in sections down the available stairwell. New pads were poured, and the equipment was repositioned in the boiler room placing the pumps to the right of the boilers.

The new equipment improved the facility’s energy consumption, reduced the carbon footprint, and integrated seamlessly with the existing BMS to monitor and control operations.

The Armstrong pumps come equipped with high-efficiency NEMA-premium motors to significantly reduce energy costs.

The Weil-McLain boilers achieve 85.6% thermal efficiency and offer LEED compliance.

With the new configuration, all of the equipment is now easily accessible, and control panels and gauges are comfortably visible. The Weil-McLain boiler solution makes maintenance and clean out tasks easier, also saving the taxpayers of Nassau County money on routine maintenance.

The Result

As a result of this project, facility workers and garage personnel have the temperature regulation they need to work productively. The updated equipment is easier to maintain, operates more efficiently and reliably, and is backed by a solid warranty. The equipment runs more efficiently using less energy and reduces the carbon footprint of the facility.
