Large Hospital Automation Upgrade, SOUTH OF BOSTON, MA
We 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 replaced obsolete air handling unit (AHU) controllers with new building automation control network (BACnet) controllers, without any interruption to ongoing critical operations.
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, we upgraded their 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 controller
- Enhancing logic for the chilled water supply plant, economizer/free cooling controls, humidity control, and pressure control
- Re-engineering and re-programming two existing AHUs using dew point control on existing desiccant wheels
To round out this project, we provided the client guidance on capital upgrades and various engineered renovations throughout the building.
This facility is a local hospital south of Boston, Massachusetts.
