20 miles of tubing will help heat and cool facility at Michigan campus

From The Detroit News: Twenty miles of tubing running through water retention ponds will help supply heating and cooling to Saginaw Valley State University's new Health and Human Services Building in University Center, Mich. The cost-saving system will transfer heat from the building to the water in the summer and draw heat from the water to warm the building in the winter, the school said. The 90,000-square-foot, $28 million building is to open in August 2010. It will have 13 labs, 12 classrooms and office space.
