Where is Virginia Tech?
Virginia Tech
Distinguished by a towering 180-foot-high radial brick smokestack, the university's Central Steam Power Plant generates an annual steam output greater than 943 billion BTUs and provides campus buildings with a portion of their heat, hot water, and electricity needs. Nearly 90 percent of campus buildings are connected to the plant through an extensive network of underground tunnels—the main access point is on the Drillfield—and more than six miles (9.7km) of steam lines and piping provide heat to more than 6.8 million square feet of campus buildings. Only personnel with confined-space training are permitted to enter the tunnel system, comprising 2.76 miles (4.44km) of inaccessible tunnel and 11.07 miles (17.82km) of piping; 3.78 miles (6.08km) of direct-bury piping in the ground; and 2.2 miles (3.5km) of accessible tunnel and 12.27 miles (19.75km) of piping.[112]
