Envision Charlotte was established as a 501(c)3 in 2011 focused on economic development through sustainability. Envision Charlotte’s first initiative was in partnership with Duke Energy focused on reducing energy in our Center City. Charlotte’s uptown has 64 buildings with 10,000 square feet or more of commercial space and 61 of those buildings signed an energy pledge to reduce their energy by 20%, put a shadow meters in their building and a kiosk in the lobby showing the aggregate energy use of all the buildings.
