Coupled with the fact that nearly all construction waste was recycled, the building reduced the volume of landfill material. “We pulled 500 times more out of the landfill than we put back in,” said Stu Carron, the company’s director of global facilities and real estate. (The company used bottom ash, the black, granular left-overs from coal burning at power plants, for the sub-base instead of the normal crushed, quarried rock.)
Energy savings were built in from the start. “Builders were competing on how ‘green’ a building they could build,” Carron said. “The surprising result for many people was that the company that gave us the highest level (of energy efficiency) was also the lowest bidder.”
The company released a global responsibility report in June.
