Walsh Corporation expanded its Chicago headquarters and achieved Platinum LEED certification. Green features like a green roof, demand control ventilation, solar ducts, and lighting controls reduced energy use. The rehabilitation incorporated these innovations while gutting and renovating the building over 2010-2011. The project team included Walsh Construction, McGuire Engineers, Solomon Cordwell Buenz architects, and FE Moran mechanical contractors.
