  3. 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.

  4. 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 Star’s 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- 8’s 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

  8. Occupancy Sensors LocationAverage Savings Amount Annual Savings (per room) Private Offices 35% 600 $7.59 - $12.56 Classrooms 40% 35 $18.40 - $49.06 Conference Rooms 47% 62 $10.29 - $20.58 Restrooms 54% 121 $35.50 - $59.13 Storage Areas 60% 264 $7.88 - $15.77 Lounge/Kitchen 35% 90 $13.80 - $27.60 Waiting Room 30% 50 $26.28 - $52.56 Exam Room 50% 121 $6.57 - $13.14 Total Savings: $15,497 to $28,591 in electricity per year 310,119 to 571,747 kWh per year

  9. 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.

  10. Air Audit Equipment used: UE Systems 9000 Ultrasonic Leak Detector Compressed Air 20 leaks for a total loss of 74.8 CFM Total loss of $7,862.98 and 157,260 kWh per year Medical Air 11 leaks for a total loss of 22.9 CFM Total loss of $3,009.06 60,181 kWh per year Steam 5 leaks for a total loss of 35.12 lb/hr Total loss of $3,999 and 331 Mbtu per year Total: $14,871, 217,441 kWh, and 331 Mbtu per year

  11. Energy Star Products Product Savings (1 unit per year) Total Savings (per Year) CRT/LCD Monitor $8 $10,500 TV $3 $2,190 Vending Machine $140 $10,500 Computer $6 $3,600 LED Exit Signs $12 $6,000 Other products: Copiers, printers, refrigerators, DVD’s, fax, and food service equipment Total Savings: $27,090 per year 500,000 kWh per year

  12. Monitor Power Management This free software from Energy Star puts all monitors on the network into sleep mode after a pre-determined time. Estimated savings per monitor: $10-$20 Total Savings (based on 1,500 monitors): $15,000 to $30,000 per year 300,000 to 600,000 kWh per year Cisco Systems Success Story: 20,000 monitors Total savings of $528,000 or $26 per monitor per year Only 16 hours of IT time to implement

  13. Energy Awareness Program Newsletter Ad Makes sure employees are an active part of energy savings. Fact Sheets Will remind people of energy conservation acts and benefits. Posters Constant reminder to turn off the lights and office equipment at night. Total Estimated Savings (from Energy Star): $30,000-$76,000 per year 600,000-1,520,000 kWh per year
