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 Audit12 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.

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.

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

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 costsT-8: 38,350 to 45,950 T- 8’s in the 4 main buildings

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 roomsImplement 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.
