The Mill 19 project converted a former industrial mill into a new high-tech facility striving for LEED v4 Platinum certification. RIDC Mill 19, a former steel mill located on the 178-acre Hazelwood Green site is the last large riverfront brownfield within Pittsburgh city limits. With the revival, reuse and occupancy of one of its three buildings, RIDC Mill 19’s design features a building within a building concept to showcase the community’s past, present and promising future. The mill’s metal walls, and roof have been stripped away to reveal its underlaying steel superstructure while maximizing energy efficiency and building material reuse. RIDC also abated large quantities of galbestos and lead during this process, preventing further contamination of the surrounding environment. One of the largest rooftop solar arrays in the country recently went live on top of RIDC’s Mill 19 superstructure. 110,000 square feet of high-powered solar panels cover the entire rooftop area and will produce over two million kilowatt hours (kWh) per year, enough to power the entire existing facility.
