The green labels are intended to tell citizens the buildings’ carbon footprint, current energy use and planned long-term reductions in energy use (by 2050). The stats are all relative to the square footage of each building.
The county’s main administrative building, at 2100 Clarendon Boulevard, is one of the buildings that will be receiving the labels. The building is 30 percent more efficient than the average U.S. office building, according to its label. Its 17.9 pounds of carbon dioxide per square foot carbon footprint compared favorably to the U.S. office average of 26.1 pounds.
