Piedmont Natural Gas’s Tennessee operations centre facility has secured LEED Gold certification from the US Green Building Council.
Sustainable measures during the construction included conservation of five acres of wetland adjacent to the property.
The centre features on-site bioponds that help manage storm water runoff with the assistance of resident beavers.
A partial green roof featuring cisterns to collect rain water for use in on-site irrigation reduces water consumption at the facility.
Other green features include parking lights that run on solar energy, automatic dimmers that lower the LED lights and a HVAC system that monitors carbon emissions.
