One of America’s most iconic buildings earned LEED for Existing Buildings.

By improving their operations, the Department of Treasury’s headquarters next to the White house has slashed energy, steam and water consumption to save taxpayers $3.5 million per year.

The oldest LEED building ever certified also increased office density by 164 units, which equals big savings in avoided new office space.This is a moment to step back and applaud what has been done.
