The Tower at PNC Plaza is a 33-story skyscraper in Pittsburgh, Pennsylvania. It is the corporate headquarters of the PNC Financial Services Group and has approximately 800,000 square feet (74,000 m2), standing 33 stories (545 feet) tall. Nearby buildings totaling 37,000 square feet (3,400 m2), were purchased by PNC and deconstructed to make space for the Tower at PNC Plaza. It is located at the intersection of Fifth Avenue and Wood Street, where PNC and its predecessors have been based since 1858. The project was estimated to cost $400 million when announced in 2011 (or $482 million today).Construction began in spring of 2012 and was completed in October 2015. The tower is one of the greenest high-rises ever built, and even exceeds the current criteria for a LEED Platinum certified building. The Tower features numerous sustainable attributes such as an operable double-skin facade, an onsite grey water reuse system, locally sourced building materials, fixtures and furniture made from recycled materials, and numerous other green strategies to substantially reduce the environmental impact of the building. Some of these features enable the Tower's heating and cooling systems to operate in a "net-zero-energy state" up to 30% of the year. This is accomplished by its innovative solar chimney, which creates a stack effect through the core of the building to ventilate excess heat without the need for mechanical ventilation. The Tower's sloped roof acts as a solar collector and is positioned facing south. The tower's "topping off" ceremony was held Tuesday, June 24, 2014, with William Demchak, PNC chairman, president and CEO, and Gary Saulson, director of corporate real estate hosting it on site. The tower officially opened on October 2, 2015.

The Farmers Bank Building was a 27-story, 105 m (344 ft) skyscraper in Pittsburgh, Pennsylvania completed in 1902 and demolished on May 25, 1997. The University of Pittsburgh's online digital library states the building was constructed in 1903 and had 24 stories. To a generation of Pittsburgh sports fans the building is well remembered for being resurfaced in the mid 1960 in a failed rehabilitation but also fondly for a 15 story high mural of Roberto Clemente, Bill Mazeroski, Jack Lambert, Mean Joe Greene and Mario Lemieux completed in 1992 by Judy Penzer, who was killed in the crash of TWA Flight 800 four years later. For the five years the mural existed it was often the centerpiece for national networks cutting to or from games while they were in town for sporting events. Rockwell International owned the building starting in the mid-1960s and used it as its global headquarters, selling it in early 1972 and consolidating its headquarters staff in the U.S. Steel Tower blocks away.The building was imploded by Controlled Demolition, Inc. on the afternoon of May 25, 1997. In its place, a low-rise department store named Lazarus was built on the site. That building has since been extensively redesigned and now operates as a condominium development named Piatt Place.
