Nanticoke Hospital, Nanticoke Health Systems

New Central Plant System Yields 15% Annual Energy Cost Savings and Improved Redundancy for Hospital

Problem

Recent renovations to the Nanticoke Hospital increased the load capacity and overtaxed the existing boiler system and chilling system. Adequate redundancy was also a concern.

StudioJAED considered the following problems when designing the central plant renovation for the hospital:

• Keeping the hospital running: It was crucial that no systems went down during the renovation.
• Coordinating deliveries and construction teams: Keeping this project on schedule meant that equipment needed to be delivered on time for the construction teams to complete their work.

Solution

StudioJAED tackled this central plant renovation in two phases:

• Phase One: Boiler Planning and Replacement - 2015-2016
• Phase Two: Chiller System Replacement - 2016-2016

During the project, StudioJAED:

• Designed temporary boiler and chiller installations to be implemented during the construction process to ensure no interruption in service.
• Coordinated purchase and delivery of boiler and chilling equipment to ensure project stayed on schedule.
• Replaced the inefficient 4-boiler system with a highly efficient steam boiler system. The new boiler controls excess oxygen, so less energy is wasted.
• Installed efficient new air-cooled chilling system.
• Designed Building Automation System so hospital administration can effectively control systems.

The design of the new boilers and chillers added crucial redundancy to the hospital’s systems, a critical factor for any hospital. The new state of the art steam boiler and the efficient air-cooled chiller offer an increased load capacity that will fit the hospital’s growing needs.

Impact

Annual savings of 15% on utility bills can be expected thanks to the O2 trim created by the new boiler and other efficiency factors will save the hospital 15% annual utility bills.

The new systems will position Nanticoke hospital to operate at a higher energy efficiency level for the next 20-30 years. As the lower Delaware region grows, efficient systems will be a critical component to the hospital’s success.

Scope of Work

StudioJAED tackled this central plant renovation in two phases:

• Phase One: Boiler Planning and Replacement - 2015-2016
• Phase Two: Chiller System Replacement - 2016-2016

In the early stages of the boiler planning and replacement phase, it became clear that the outdated chilling system should be replaced as well. Nanticoke followed StudioJAED’s recommendation to replace the chilling system as the second phase of this project. Replacing these two systems close together made sense from an energy efficiency and budget standpoint.

During the project, StudioJAED:

• Designed temporary boiler and chiller installations to be implemented during the construction process to ensure no interruption in service.
• Coordinated purchase and delivery of boiler and chilling equipment to ensure project stayed on schedule.
• Replaced the inefficient 4 boiler system with a highly efficient X steam boiler system. The new boiler controls excess oxygen, so less energy is wasted.
• Installed new air-cooled chilling system. This system is the most efficient system on the market today.
• Designed Building Automation System so hospital administration can effectively control systems.
