Energy benchmarking for hospitals
Protect your hospital dollars with energy efficiency
Hospitals consume significant amounts of energy. In fact, they have a higher energy intensity than any other activity in the commercial and institutional sector with the exception of food or beverage stores.Footnote1 Their high energy consumption is largely due to the use of very energy-intensive equipment such as ventilation systems and specialized medical equipment, as well as extended operating hours.
More and more hospitals see the value of becoming more environmentally sustainable and are looking at savings opportunities that include making greater investments in energy efficiency. Energy benchmarking is a great place to start, and the U.S. Environmental Protection Agency has found that buildings that benchmark can save an average of 2.4 percent on their annual energy budgets.Footnote2 As a result of using energy more efficiently, additional resources can be reinvested for core medical services including medical staff and equipment and other patient services, as well as contribute to a healthier environment through reduced emissions.
There is no need to wait. Start benchmarking your energy performance now: turn your energy dollars into health care dollars today.
Collect the data you need to benchmark your hospital
The ENERGY STAR® Score for Hospitals in Canada applies to acute care and children’s hospitals and to all buildings in multi-building campus settings or stand-alone facilities that are designed to treat patients for short periods of time for any brief but severe medical condition, including emergency medical care, physician's office services, diagnostic care, ambulatory care, and surgical care.
To obtain a 1-100 ENERGY STAR score, in addition to your hospital’s or hospital campus’ basic tombstone information, you need the following building data:
- Gross floor area for each building
- Gross floor area used for food preparation
- Number of sterilization units
- Number of Magnetic Resonance Imaging (MRI) machines
- Number of workers on the main shift
- Weather and climate (using heating degree days, retrieved based on postal code)
- Specific energy billing information for each building for all purchased energy. You will need to begin with at least 12 consecutive months for each energy source and update regularly with monthly usage data.
Note that the above information is not required to start benchmarking. You can start using the tool to track your energy performance no matter how much data you have. However, in order to obtain the 1-100 score or an energy use intensity value, you need the details above.
Apply for certification
If your hospital earns a score of 75 or higher and meets certain other criteria, it could be eligible for ENERGY STAR certification. Learn more about certification and how you can apply.
