Spectrum Health's Blodgett Campus facility in Grand Rapids, Mich. has expanded to 416,000 net ft2 (38 600 m2), which includes operating rooms, an emergency department, labs, patient rooms and a medical office building. The facility's continued growth and its increase of internal equipment loads created a need for more cooling capacity. The facility's cooling requirements on summer days with high wet-bulb temperatures exceeded the central chilled water plant's capacity.
