The Marshfield Clinic is incorporated sustainability principles in the construction of a $42 million new hospital campus under construction in Rice Lake.

BWBR Architects in St. Paul and its design partners have designed the project to conserve natural resources, reduce operating energy costs, and provide a quality indoor environment, said Edward Wolf, chief executive at Lakeview Medical Center in Rice Lake. . . .

The project’s energy-saving features include efficient lighting, air conditioning and plumbing systems. Lakeview’s board of directors committed to maximum energy use 15 percent below the state’s current building code limit. To meet that goal, the building ventilation design will recover heat from air exhausted out of the building that will heat incoming air, said mechanical engineer Linda Weingarten of Minneapolis-based Dunham & Associates, the project consulting engineering firm.

Heat given off by chillers that cool the building will be used to heat hot water, lowering electric usage during summer, she said.

“This isn’t new technology, but it’s the first time we’ve used it in a hospital project,” she said. The design is expensive, and wouldn’t be cost-effective if retrofitted in an existing building, she said.

High efficiency condensing boilers also will help lower fuel consumption year round.

Increased roof insulation values and high performance windows also will help reduce energy costs.
