Making your facility more energy efficient

November 12, 2021
From the November 2021 issue of HealthCare Business News magazine

ENERGY STAR certified healthcare facilities don’t achieve extraordinary savings by applying special knowledge unknown to the rest of the industry. Rather, they put into practice a structured approach to energy management: improving operations of existing equipment, changing occupant behavior, and upgrading to new, more efficient equipment when it makes sense.

Fix what you have first
A building is like a treasure chest. The savings it hides can make you wealthy, but you must find it first. That’s why hospitals have begun to conduct Energy Treasure Hunts. These two-day events engage teams of energy treasure hunters who fan out across the hospital to look for easy energy saving opportunities.

They might find lights, computers, and other equipment that have been left on in unoccupied spaces. They may find HVAC systems that have been left running or HVAC operations beyond standard temperature setpoints; lighting that is too bright, not effi¬cient, or not directed to necessary tasks. Teams often strike gold. OSF Healthcare and Atrium Health identified $350,000 in savings from operational changes in existing equipment and small capital projects like lighting upgrades. Most of the projects had paybacks of under one year and some even had instant paybacks by reducing airflow in unoccupied areas from an HVAC system that formerly operated 24/7/365.

Change behavior
While the main purpose of an Energy Treasure Hunt is to identify opportunities to use energy efficiently, the longer-term value is culture change. These events begin a behavioral shift in how the hospital thinks about energy use. Rather than as a fixed cost of doing business, energy is thought of as a variable cost to be controlled that can save not only millions of dollars but also provide a pathway to demonstrate environmental leadership.

Teamwork is essential; all employees are invited to identify opportunities to reduce energy use. Their involvement helps create a sense of responsibility for the solutions and sparks employee ownership of energy-saving strategies. Once institutionalized, energy management becomes part of the culture and organizational health of the hospital.

Healthcare systems interested in improving the energy efficiency of their hospitals can join the voluntary U.S. EPA ENERGY STAR program. In 2018, the ENERGY STAR program for commercial buildings helped businesses and organizations save 190 billion kilowatt-hours of electricity, avoid $12 billion in energy costs, and achieve 140 million metric tons of greenhouse gas reductions.
