According to a recent report from Grumman/Butkas Associates, hospitals has shown some, but not substantial progress in being more energy efficient over the past 20 years. See https://mailchi.mp/grummanbutkus.com/hospitalsurvey2018p1-1345361.
Comparing recent surveys by the firm, hospital greenhouse gas (GHG) emissions in 2010 averaged 63 lbs CO2e/square foot(sf)-year, while in 2017, it dropped to 52 lbs CO2e/sf-year.
However, average site energy usage intensity dropped only 0.3% during that period. Total energy usage (electricity, gas/oil, steam) of participating hospitals was nearly 242,000 Btu/sf in 2017.
As far as costs are concerned, according to the 2018 benchmarking survey report, hospitals have reduced their energy costs per square foot from a peak of about $3.75/sf in 2008 to about $3.16/sf in 2017. However, given the note above that the industry made only minor progress in energy efficiency, most of this cost reduction was achieved by negotiating better supply prices, leveraging their large usage. And, most of this was on the natural gas side. These numbers are fairly similar to those developed during their first survey in 1999.
All of this data spells critical issues, and also opportunities for the hospital industry. A 2014 survey showed that 51% of hospital expenses was energy related, far exceeding staff costs. Thus, reducing energy usage can help control hospital costs, which, as we all know, is a major political issue, in terms of affordable health care for all.
One problem with attempting to reduce energy usage in hospitals is the culture of redundancy. One way to reduce energy usage and, thus, GHG emissions, too, is to reduce or eliminate redundancy. However, having extra equipment, ambulances, at the ready is an important part of how a hospital operates and thinks. A hospital cannot function thinking there is a risk to patient health due to a cutback that would “merely” save energy or GHG emissions. Therefore, investments in ensuring more reliable systems can reduce redundancy and, therefore, emissions.
I can share the story of a hospital that keeps an ambulance running on idle at all times (24/7) in its “bullpen” in case an emergency call comes in. It would certainly not be acceptable in the rare case of all the ambulances to not be able to start. Well, this policy turned into an environmental issue as the exhaust of the constantly-running ambulance got into the intake of a major hospital building and exhaust was detected in patients’ rooms (ironically, in a wing specific for patients with lung diseases). In rectifying the problem, the hospital replaced older ambulances with those with sufficient and charged batteries so that reliability was no longer an issue and they did not have to run an ambulance at all times.
