Confidential Hospital – Automation Upgrade

Upgrading to a web-based controls system, with programmable controllers, allows this hospital to fine tune its operations and more efficiently use facility maintenance technicians.

Confidential Hospital – Automation Upgrade wiring

Value Delivered

EMCOR Services Northeast (ES Northeast) reprogrammed and reengineered the hospital’s existing chilled water plant control logic to help lower energy consumption, increase reliability, and improve ease of operation. 

We also replaced obsolete air handling unit controllers with new building automation control network (BACnet) controllers, without any interruption to ongoing critical operations.

Client Objectives

The hospital wanted to modernize their existing building automation to a web-based system with programmable controllers.


As part of our longstanding, ongoing combined mechanical and controls service agreement with the hospital, ES Northeast upgraded the building automation system by:

  • Installing a new web-based graphical user interface
  • Replacing aging front end gateways and routers with new java application control engines
  • Upgrading critical equipment controls with new BACnet programmable controllers
  • Enhancing logic for the chilled water supply plant, economizer/free cooling controls, humidity control, and pressure control
  • Re-engineering and reprogramming two existing air handling units using dew point controls on existing desiccant wheels

To round out this project, we provided the client guidance on capital upgrades and various engineered renovations throughout the building.

Client Background

This facility is a local hospital south of Boston, Massachusetts.
