In 1998 SVSU started construction on a campus-wide energy loop to connect all of the main buildings on campus. Before the installation of the energy loop each building required its own chiller for cooling. The energy loop connected the chillers from all of the main buildings together in order to increase efficiency without going to the expense of building a central energy plant. The energy loop also cut down on the number of chillers needed to cool the buildings. The remaining chillers were also updated. The energy loop saved the University an estimated $100,000 annually.
SVSU also installed occupancy sensors throughout campus in 1998. The occupancy sensors placed in both classrooms and offices would turn the lights off in the room if it remained unoccupied for a certain amount of time which would save energy. The installation of the occupancy sensors saved the University an estimated $47,000 annually.
