Improving energy efficiency and shifting to clean, renewable energy can enhance patient outcomes and minimize costs.

 

Body

Reducing energy waste and procuring renewable energy are some of the most effective steps that our member hospitals are taking to reduce their environmental impact and protect community health. There are many reasons energy should be an area of focus:  

  • Inpatient health care is ranked by EPA as the second-largest commercial energy user in the United States.
  • Health care facilities consume close to 10% of the total energy used in U.S. commercial buildings and spend more than $8 billion on energy every year. 
  • The health care sector is responsible for 8.5% of U.S. greenhouse gas emissions. 

The challenge for health care systems is to “do no harm” by working to eliminate the negative health and climate impacts of our energy consumption while enhancing patient outcomes and minimizing costs. With renewable energy sources like wind and solar already outcompeting dirty energy in most of the country, this goal is becoming increasingly achievable and practical  – many Practice Greenhealth member members have found they can significantly increase energy efficiency and shift their energy mix to clean, renewable sources without huge capital outlays by using a variety of strategies.

Hackensack University Medical Center embarked on a two-phase energy conservation project that when complete will result in annual utility cost savings of $1.06 million.

Practice Greenhealth has cultivated resources and created tools to help our members identify and address their energy usage step-by-step.

Step 1: Track, measure, and benchmark current energy use

Accurate energy tracking and management tools help hospitals identify underperforming buildings, verify the effectiveness of any efficiency efforts, and identify opportunities to improve. 

Step 2: Set ambitious energy goals

As technology improves and costs continue to decline, more promising energy reduction strategies are available and accessible to health care institutions. Setting clear goals to improve energy efficiency and shifting to renewable energy will help drive impact, identify key partners, and hold your team accountable. There are a host of governmental agency tools to help with energy goal-setting. Practice Greenhealth experts frequently guide members through the process to identify the materials that will be most useful. You can also start with the goals established in the leaner energy challenge, or the Renewable Energy Buyers’ Alliance (REBA).

Step 3: Implement clean energy practices

Energy reduction practices fall into two major categories:

  • Energy Efficiency: The cleanest and cheapest energy in the world is energy you don’t use. By utilizing tactics such as retro- and continuous commissioning, lighting modifications, supplemental load reduction for HVAC systems, “rightsizing” air distribution systems, beneficial electrification, and heating and cooling upgrades, you can reduce the need for energy. 
  • Renewable Energy: Replacing conventional energy with clean, renewable energy technologies such as solar, wind, geothermal, and other renewable sources can reduce reliance on fossil fuel combustion for energy, save your institution money, and reduce the negative health impacts of pollution in the communities you serve. 

Practice Greenhealth has expertise and experience in helping our member hospitals improve energy efficiency and procure renewable energy. Utilizing Strategic Energy Master Plans (SEMPs) assembled by hospitals is an important step. Organizations like Mass General Brigham in Boston, Massachusetts have used a SEMP to help mitigate annual price increases of 1.5% in 2008 by identifying a reduction goal, increasing efficiency, and a host of other measures including implementing renewable energy. 

Additionally, we can help identify sources of energy efficiency financing and point the way for health care systems to access renewable energy using power purchase agreements (PPAs), renewable energy certificates (RECs), community solar, and other renewable energy procurement mechanisms. These approaches can help overcome barriers like finances or limited infrastructure and may be a viable option, enabling a hospital facility to claim onsite or offsite renewable energy generation. Renewable energy certificates can be used to support the increased generation of clean renewable energy.

Step 4: Report and analyze impacts

Practice Greenhealth generates a Sustainability Benchmark Report every year to track sustainability efforts and evidence-based programs. The data from our members drive the Environmental Excellence Awards, which recognize hospitals and health systems for leadership in sustainability best practices in areas including leaner energy. The dataset from the Practice Greenhealth network is invaluable and can guide hospitals to set targets. For example, in the 2020 benchmark report, the average energy intensity (EUI) score was 217. An EUI score is a measure of a facility’s electrical and gas usage over a 12-month period. Almost 70% of Practice Greenhealth award winners have a written plan to reduce energy use with timelines and goals, and the energy savings per facility was over $40,000. 


environmental excellence awards

The Environmental Excellence Awards are the nation’s premier recognition program for environmental performance in the health care sector. The Circle of Excellence Awards celebrate hospitals who have not only earned an award for all around sustainability achievement, but who have also been identified as the top scoring programs for each category of sustainability.

The Energy Circle celebrates hospitals that are leading the sector in energy efficiency. Leaders generally have energy managers and written programs to reduce energy use over time. They are tracking energy use intensity, ENERGY STAR performance metrics, and shared details on project implementation and staff engagement strategies.
