Introduction to the Country’s Largest All-Electric Hospital
A new hospital at UC Irvine is set to open, marking a significant milestone in the healthcare industry’s shift towards sustainability. The hospital, which will be the largest all-electric medical center in the country, is a beacon of hope for a future where healthcare and environmental stewardship go hand-in-hand. As people spend some of the most vulnerable moments of their lives in hospitals, it’s essential that these facilities are not only comfortable but also environmentally responsible.
The Need for Sustainable Hospitals
Hospitals traditionally rely on natural gas lines to ensure a consistent supply of hot water and temperature control. However, burning natural gas is a significant contributor to climate change, with the built environment accounting for over one-third of global greenhouse gas emissions. The new UC Irvine hospital is a game-changer, with its 144 beds and entirely electric infrastructure. This innovative approach is not only better for the environment, but it also provides a healthier and more comfortable space for patients and staff.
A Tour of the Hospital’s Sustainable Features
A tour of the hospital’s facilities reveals a range of sustainable features, from the electric kitchen to the heat pumps and centrifugal chillers. The kitchen, where patients can enjoy fried foods and other treats, is equipped with an electric fryer and an infrared grill that can sear steaks and burgers to perfection. The hospital’s water heaters, which are a significant energy drain in most facilities, are also electric, with a row of 100-gallon water heaters that stretch 20 feet long. As Joe Brothman, director of general services at UCI Health, notes that the hospital’s electrical load is immense, but the benefits far outweigh the challenges.
Backup Power and Future Improvements
While the hospital is a significant step forward in terms of sustainability, there is still room for improvement. The facility relies on diesel generators for backup power, which, although necessary for emergency situations, do produce emissions. However, as Alexi Miller, a mechanical engineer and director of building innovation at the New Buildings Institute, notes, solar-plus-storage systems could provide a cleaner alternative. Miller suggests that the hospital could have utilized more efficient heat-pump hot water heaters, which would have been three to four times more efficient than the current resistance heat technology. Despite these areas for improvement, the hospital is a milestone in the journey towards more sustainable healthcare facilities. As
