Small changes add up to big energy $avings in the radiology department

PARCA eNews – Sept. 30, 2014 – In a single institution study, radiologists found that small steps to save energy in the radiology department saved $11,629 over a 12-month period. The small steps amounted to shutting off equipment when not in use.

The study by the radiology department at St. Vincent's University Hospital in Dublin, was published online Sept. 4, 2014 in the journal Academic Radiology.
The medium-sized department has 43 desktop computers and 27 PACS workstations. They measured electrical consumption with a power monitor over the course of a week and then calculated the cost at $0.10 per kWh for a year.

They found that 29 of 43 desktop computers and 25 of 27 PACS reporting stations were left on unnecessarily overnight and on weekends resulting in a cost of $7,253 per year. They estimated that turning those off along with the energy used by conference facilities when not in use could save over $11,000 per year.
