Providence Holy Cross Medical Center’s new four-story, 138-bed expansion was named the first LEED Silver hospital in Southern California, an honor bestowed on buildings that meet certain environmental standards.

The U.S. Green Building Council’s LEED program – Leadership in Energy Efficiency and Design – is the nation’s preeminent program for the design, construction and operation of high performance green buildings.

“This exceeds the goals and expectations for the project,” Patty Mayberry, R.N., project manager for the new wing, said in a statement. “Everyone who worked so hard to complete this project, including our contractors and architects who documented the many features of the building, share this honor.”

LEED certification is based on a number of green design and construction features that provide positive impacts for the building itself as well as the broader community. LEED has four classifications of certification based on the number of green features documented: certified, silver, gold and platinum.

Among the many environmental-friendly features of the building on the Mission Hills hospital campus are energy saving roofing materials, erosion control, bicycle stations and changing rooms, water bottle refilling stations, water efficient landscaping, an air-conditioning system designed to reduce potential ozone depletion, diversion of 75 percent of construction waste from landfills, composting and the elimination of plastic foam products.

“LEED certification shows that Providence Holy Cross is living its core value of stewardship and contributing beyond its walls to help create a healthy community,” said hospital CEO Larry Bowe in a statement.

It was the community that urged Providence Holy Cross to incorporate green features in building and operating the new $160 million patient tower when ground was broken in 2007.

The new wing opened in July and includes a new Women’s Pavilion with private labor-and-delivery suites and dedicated operating rooms, a 12-bed neonatal intensive care unit, a new gastroenterology laboratory and much-needed additional patient beds.

Swinerton Builders was the general contractor on the expansion; the Stahl Companies managed the project and HMC Architects designed the building.
