On a cloudy Thursday morning, Tom Cavender walks across the WakeMed North Hospital in Raleigh, explaining how the constructing is designed for vitality effectivity.
“Healthcare is such an vitality hog. One of the best factor we are able to do is develop our amenities in order that they function [as] successfully and effectively [as possible],” mentioned Cavender, the vp of Amenities and Building at WakeMed.
Hospitals want uninterrupted electrical energy. In case of emergencies, akin to hurricanes, all healthcare amenities have backup turbines.
He stands by the primary entrance of the hospital and factors up towards the home windows.
“On this elevation, which is the south elevation, you may see that we now have sunshades above each window,” mentioned Cavender. “That orientation, and the angle of these sunshades, replicate the peak of the solar in the summertime after which that washes the affected person home windows with shade, as an alternative of sunshine. Within the wintertime, when the solar is decrease, it goes under the shades, and we… get the photo voltaic achieve of the warmth.”
Each facet of the hospital has totally different formed home windows — some wider, some smaller. All of them are designed to maximise daylight relying on the season and which manner they’re dealing with. This helps preserve vitality and lower your expenses.
“A few of our newer amenities that we have constructed over the past 5 to 10 years — we’re in all probability working at about 50 to 75 cents a sq. foot lower than what we have been previously,” Cavender mentioned. “And that is considered the speed will increase.”
WakeMed additionally makes use of gray water for its irrigation programs. Gray water is leftover, untreated water that has already been used, together with water from washing machines, bathtubs and loo sinks.
“We’re in all probability saving half 1,000,000 {dollars} a yr in water bills,” Cavender mentioned.
In the meanwhile, WakeMed doesn’t know the way a lot carbon emissions its hospitals emit a yr. Cavender says figuring that out will probably be a part of a sustainability plan he hopes to have completed by the tip of subsequent yr.
Duke Well being and UNC Well being are in comparable positions. Neither have particular local weather motion plans in the intervening time, however each additionally give attention to vitality effectivity of their amenities. In distinction, Duke College and UNC Chapel Hill do have sustainability plans and targets.
“I feel all of this wanted to occur yesterday,” mentioned Tavey Capps, government director of local weather and sustainability for Duke College. “There’s a broadening recognition that the impression of the well being system and the connection of well being and local weather is so key.”
Capps factors to grassroots efforts occurring at Duke Well being.
“Docs, practitioners, employees, [and] college students… have fashioned Inexperienced Groups [and] participated within the college’s inexperienced office [and] inexperienced labs certification,” mentioned Capps. “I’ve labored with graduate college students doing tasks [looking at] how they are often considering extra deeply about local weather and sustainability.”
A few of these graduate college students revealed a report earlier this yr analyzing Duke Well being’s carbon emissions. The report discovered that Duke College Hospital emitted roughly 104,000 metric tons of CO2 from July 2018 by means of June 2019.
This report was shared with senior management in Duke Well being, together with outgoing Duke Well being President Eugene Washington, who fashioned a Local weather Change Well being Fairness Committee to speak about sustainability efforts.

Duke Well being intends to start out work on a local weather motion plan as soon as a brand new president is in place.
“We’re within the early phases of planning sustainability initiatives, working intently with our colleagues on the campus facet in addition to leaders and frontline workers in our medical enterprise,” a Duke Well being spokesperson mentioned in an emailed assertion.
UNC Well being didn’t make anybody obtainable for an interview with WUNC. In an emailed assertion, spokesperson Alan Wolf mentioned UNC Well being continues to be within the early phases of discussions about broad sustainability efforts.
“We’re varied initiatives associated to waste administration, vitality use, water use, and meals. And we now have some nice work underway. For instance, we’re constantly getting excessive marks for recycling,” Wolf mentioned. “A number of new amenities … are LEED licensed based mostly on sustainable vitality and carbon-based emissions.”
LEED is a constructing system that stands for Management in Power and Environmental Design. The U.S. Inexperienced Constructing Council (USGBC), a non-profit that promotes sustainability in constructing designs, runs this system. LEED licensed buildings “enhance effectivity, decrease carbon emissions” and assist handle local weather change, in line with USGBC.
A number of Duke Well being and WakeMed amenities are additionally LEED licensed.
Just like Duke Well being, there are grassroots efforts occurring within the UNC College of Medication. Hope Gehle, a third-year medical pupil, is main efforts for CLEAN Med UNC, a pupil group whose predominant focus is pushing for a healthcare sustainability curriculum.
“[UNC is] within the midst of adapting the curriculum already,” Gehle mentioned. “[Faculty and staff] are actually receptive.”
The group additionally publishes a Planetary Well being Report Card, a global “metric-based instrument for evaluating and bettering planetary well being content material in well being skilled faculties.” This yr’s report suggests UNC ought to make a devoted planetary well being educational program and examine the carbon footprint of UNC Well being, which has not been completed.
“I’ve not been in any conversations with [UNC Health],” Gehle mentioned. “They’re a little bit bit more durable to come up with, truthfully.”
Gehle works intently with Carolina Advocates for Local weather, Well being and Fairness (CACHE), a bunch of healthcare employees calling for local weather options within the business.
Kathleen Shapley-Quinn is the chief director of CACHE and a practising household doctor.
“It’s such a paradox that the establishments that we depend on to make us higher, in some methods are actually making us lots worse,” Shapley-Quinn mentioned. “Well being programs do a fairly good job [at taking care of] a person who has had an harm or sickness. However on the identical time, they’re worsening the local weather of the setting.”
CACHE plans to achieve out to healthcare programs, suppliers and organizations early subsequent yr to speak about sustainability efforts. Shapley-Quinn says she’d wish to see all healthcare programs in North Carolina take a federal pledge to be carbon impartial by 2050.
Atrium Well being in Charlotte signed onto that pledge.
“We have all the time believed there’s been this hyperlink between well being and the setting. When the chance introduced itself, we wished to be part of that dedication,” mentioned Jennifer Sellers, director of enterprise operations for environmental sustainability at Atrium.
In response to its web site, Atrium has decreased its annual vitality consumption by 30% in comparison with 2012 ranges.
Sellers says some ongoing initiatives embody lowering single use plastics and consolidating their car fleet. However there are challenges, like making an attempt to collect metrics on carbon emissions from distributors of their provide chain.
“There isn’t any one measurement suits all with it. It is not like it may this magic dashboard or something like that,” Sellers mentioned. “We’re making an attempt to determine – how can we collect this info? How can we take a worth out of it?”
One other extraneous issue is that every one these healthcare programs get at the very least some, if not most, of their electrical energy from Duke Power.
A state legislation handed final yr requires Duke Power to be carbon impartial by 2050. The North Carolina Utilities Fee is anticipated to launch that carbon plan by Dec. 31.
