US company PNC Financial Services Group has announced plans for the construction of an environmentally friendly skyscraper to house the company's headquarters in Pittsburgh, Pennsylvania, US.
The new building will have an area of 74,300m² spread over 40 storeys.
Plans for the tower include street level retail, green rooftops and 300 underground parking spaces.
The tower will feature a double glass façade aimed at enhancing energy efficiency by reducing cooling costs and allowing natural airflow into the building.
The design also orients the building to take advantage of sunlight in workspaces, reducing the need for artificial lights during the day.
Fuel cells, solar panels and geothermal systems are being discussed to help reduce carbon emissions.
The project is being designed by Gensler, PJ Dick is the construction manager and Buro Happold will provide engineering services for the project.
Construction is expected to commence in late 2011 with completion scheduled for 2015.
