Gundersen Lutheran Health System is a regional hospital with numerous supporting clinics. Their goal is to minimize their carbon footprint in a cost effective manner to get the approval of the CFO. Each building has a different lighting system. In addition, Energy Performance Lighting (EPL) must work with hospital staff to avoid interupting hospital processes to successfully implement this project.
EPL retrofitted the existing light fixtures and reduced the number of lamps per fixture from three or four to one or two lamps all while following Recommended Practice of the Illuminating Engineering Society (IES). The work schedule was designed to install during first and second shift depending on the occupancy. Surgical suites were scheduled around the facilities needs. The buildings were completed one at a time with a walk through and punch list developed for final approval. Energy consumed was reduced by 47% and the CFO approved the project.
