Show Me the Beef – Proving the Value of the HFCx Process
• ASHE Process for HFCx and HFRCx is Significantly Different than Conventional Practices
• ASHE Process for HFCx and HFRCx May Cost More
• Is the ASHE Process Worth the Additional Effort?
• 4 Case Studies • Clay County Hospital, Jacksonville, FL • UAB Women and Infants Center, Birmingham, AL • Baptist Hospital, Nashville, TN • Sacred Heart, Port St. Joe, FL
• Scope, Costs, and Benefits for Each Case Study
Learning Objectives • Understand the Basic Components of the
HFCx Process
• Learn How the HFCx Process Yielded an ENERGY STAR-Rated Hospital After Its First 12 Months in Operation
• Understand the Basic Components of the HFRCx Process
• Learn How the HFRCx Process Implemented by Hospital Maintenance Staff Increased its ENERGY STAR Rating from 13 to 72
• Learn How the HFRCx Process Reduced the Energy Costs of a Critical Access Hospital by more than 40 Percent
• Learn Why a Large Health Organization has Standardized the Use of the ASHE Commissioning Process

ASHE Definition of Commissioning
“Commissioning is a process intended to ensure that building systems are installed
and perform in accordance with the design intent, that the design intent is consistent with the Owner’s Project Requirements,
and that operations and maintenance staff are adequately prepared to operate and
maintain the completed facility.”

Energy Awareness Newsletter
Baptist Hospital
me (MyEnergy) is the campus wide Energy Conservation Program at Baptist Hospital.
Did you know: The average monthly electric bill for the main hospital building is
$215,855.00 and we use 2,743,578 kilowatts. Compare that to your electric bill at home.
My Energy at work: WOW! Think of the above statement. What do you use in your area
that uses electricity? What you turn on does matter. What you turn off also matters.
My Energy at home: It’s winter! Do you use all electric heating at home or natural gas?
Do you have a predictable schedule that would benefit from having a programmable
thermostat when no one is home? If you manually set the thermostat back before you leave
home, consider how many times you have forgotten. Programmable thermostats don’t get
busy and forget. If you don’t have one, go to Home Depot, Lowes or any other hardware
stores and purchase one that matches your system requirements. If you aren’t sure what to
purchase, the sales associates can help you. After one is installed and set for your daily
schedule, you can relax knowing you are saving energy automatically.
