Lack of Capital Expense Budget, Occupant Comfort, Sustainability Targets

Mercy is guided by the core values of Dignity, Excellence, Justice, Service and Stewardship. As part of their sustainability and stewardship objectives, Mercy intends to reduce energy use by 20% while simultaneously transforming customer care. Mercy had budgeted for a lighting upgrade, but even with available utility rebates, the annual capital expense budget would allow for only partial updates to select buildings. Leadership realized this would take years to complete and they would not meet their sustainability goals across all hospitals.


Mercy chose to completely retrofit Mercy Jefferson Hospital, replacing all existing fluorescent lamps with LEDs including Enlighted smart lighting controls. This amounts to 2,000 fixtures or 4,300+ individual lamps. Mercy Health chose to leverage Enlighted’s GEO program to:

  • Maximize potential energy savings without the need for large capital output
  • Minimize the time to completion of all properties
  • Improve hospital building value and overall customer care through improved lighting

With a full equipment change from existing fluorescent lamps to LED’s including Enlighted smart lighting controls, Mercy Jefferson Hospital will realize substantial annual savings of over 1,926,733 kWh from the retrofit. This represents an annual savings of $138,725. Expected savings over 5 and 10 years are $693,624 and $1,387,248 respectively. Savings within the hospital’s different uses will vary from the lowest (hallways/lobbies) of 70% to the highest within office and patient care with 88% and 80% respectively.
