Verified ZNE Portfolio Case Study: Gundersen Health System

Case Study / October 10, 2016 / Getting to Zero

Gundersen Health System is the largest portfolio of buildings striving to reach zero net energy performance on a district wide scale in North America. The portfolio is made up of 45 new and existing buildings and spanning more than 2.5 million square feet of floor area, Gundersen has consistently worked towards achieving energy independence with increasing success. Hospitals account for only 2% of commercial floor space in the U.S. but use 5.5% of all commercial building energy. Operating a zero net energy portfolio of health-care facilities in a challenging climate like Wisconsin makes this achievement all the more impressive.
