DALTON, Ga.– Hamilton Medical Center has been embracing a more
“green” concept. Several initiatives have improved the sustainability of
In recent years, Hamilton has been faced with aging assets of its physical plant. Some equipment either needed significant maintenance or to be replaced. Hamilton engaged Sodexo, the company that oversees the hospital’s facilities, to perform an in-depth engineering study to provide analysis and make recommendations for all facility assets, forming the basis of Hamilton’s capital improvement plan. The initiatives focused on sustainability and reducing energy consumption.
According to Don Meeks, operations manager, it has been a four-year process. Projects included upgrades to Hamilton’s chilled water plant and air handling units, replacement of the emergency generator (to increase reliability and capacity to support growth), and integrating upgrades into the building automation system.
In addition to efficiency and operational savings for Hamilton, these upgrades improve patient and employee comfort.
Regulating temperature is a much more efficient process now, according to Meeks. “Hamilton’s new automation system allows for quicker response because it’s now web-based,” he said. “Instead of calling in someone when there’s an issue, the system can be accessed online, and many issues can be corrected in a matter of about 5 minutes instead of 45 minutes.”
Sodexo’s turnkey solution to the air handler system involved splitting the system into two parts with a wall that kept one side running while the other side was being built. The switchgear project was equally innovative and ensured no interruptions to the hospital’s operation. When the Sodexo team was ready to change out electrical panels, the work was scheduled so that every hospital department could operate with no downtime.
The upgrades provide $495,000 of annual savings, which allows Hamilton to reallocate funds toward infrastructure renewal, focusing on sustainability for the future.
