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.
