Medical Imaging Equipment Energy Use Study


Health care facilities have high energy intensities: they typically provide services 24 hours a day, seven days a week, and use energy-intensive equipment.

ENERGY STAR® products are available in many consumer and business categories to help purchasers select the most energy efficiency products in a specific category. Currently, there is no ENERGY STAR® designation for high energy-consuming medical imaging equipment used in North American hospitals. The United States Environmental Protection Agency (US EPA) has taken the lead in assessing the opportunity to designate a new category of medical imaging equipment as ENERGY STAR® certified. Natural Resources Canada (NRCan) has been providing assistance to the US EPA to address these opportunities North American-wide.


The Canadian Coalition for Green Health Care was approached by NRCan to undertake a study to gather energy data for six types of medical imaging equipment that have been pre-identified as possible candidates for ENERGY STAR® certification:

  • Computed Tomography (CT)
  • General Radiography (X-ray)
  • Magnetic Resonance Imaging (MRI)
  • Mammography Equipment
  • Nuclear Imaging
  • Ultrasound Imaging/Sonography

The US EPA is interested in identifying if the ready-to-scan mode or low-power mode of medical imaging equipment are opportunities for energy savings.

The Coalition is partnering with two hospitals to gather this energy use data. Results are expected April 2017.
