Via Christi Overview
Via Christi Regional Medical Center is a
non-profit Catholic health organization based in
Wichita, Kansas.
I worked at their St. Francis campus. St.
Francis is a 1,450,000 square feet Level-1 Trauma
Center.

Energy Consumption Audit
12 months of energy data was collected for St.
Francis, St. Joseph, Our Lady of Lourdes, Good
Shepherd, and 30 other locations owned by Via
Christi. The 4 main buildings were placed into
Energy Stars Portfolio Manager to get a
benchmark reading.
5
Energy Consumption Audit

• St. Francis meters were broken down into the
  location they served, what events happen in those
  locations, and per square foot.
• All this information was collected to allow the
  hospital to focus their energy conservation on
  the locations where they use the most energy.
• An example of the final spreadsheet can be seen
  below.

6
Light Audit

• Overall higher lighting levels than needed.
• Recommendations
• ¼ Delamping- 25 locations
• In locations that are over lit constantly
  and/or low traffic hallways
• Turn off certain lights during the day- 21
  locations
• Achieve through timers or connecting the
  lighting to a Building Automation System
• 21 timers are needed a purchase price of 630
• Benefits
• 5,793.27 and 125,068 kWh savings in electricity
  per year
• Removal of 336 lamps

7
New Lamp Purchases

• A list of the current lamp purchases for St.
  Francis and St. Joseph was reviewed to determine
  if there are better options.
• 11 lamp types were identified that should be
  changed.
• The new lamps reduce electricity, lamp disposal,
  mercury, and/or maintenance costs
• T-8 38,350 to 45,950 T- 8s in the 4 main
  buildings
• Savings
• 81,920 to 97,302 in electricity per year
• 1,638,387 to 1,946,005 kWh per year
• 69,030 to 82,710 mg of mercury

• Total Savings
• 15,497 to 28,591 in electricity per year
• 310,119 to 571,747 kWh per year

Dimming Controls

• Dimming controls offer occupants more control
  over their environment.
• They can be used in patient rooms, offices, and
  exam rooms.
• Occupancy sensors save more in offices then
  dimmers do.
• Dimming controls, in exam rooms, have no
  research on potential savings.
• Patient rooms
• Implement dimmers during renovations or new
  construction.
• There are 730 patient rooms.
• The chart below shows the estimated savings per
  year if dimmers were placed in patient rooms.
