The Tower at PNC Plaza

The Tower at PNC Plaza, the new headquarters of PNC Financial Services Group in Pittsburgh, Pennsylvania is planning to install Isokorb® thermal breaks this fall in the 32-story building.

Currently under construction, the tower has been reported to be the "world's greenest" office tower.  Hao Ko, design director for Gensler architects, created the plan for a naturally ventilated office tower. He describes the Tower as a "building that will breathe." The steel structure is wrapped in a double curtain wall, with automated windows on the exterior and flaps on the interior that will bring in fresh air.

Schöck Isokorb will be installed in line with the tower's interior curtain wall, contributing to the building's high efficiency and thermal performance of the façade.The structure will use more than 3,000 meters (1.9 miles) of Isokorb CM modules along the edge of 30 levels with double-skin façade.
According to Erleen Hatfield, PE, LEED AP, AIA, Partner, Buro Happold, "To provide fully integrated engineering service for The Tower at PNC Plaza, it was incumbent on the structural engineers to understand and embrace the high-performance goals of the project. We saw the introduction of the thermal break into the structural system as a way to improve the envelope and energy performance, and reduce the need for the perimeter mechanical systems, which prevent condensation and drafts."
Upon completion in summer, 2015, it is expected to be the country's "tallest tower relying on such a passive strategy for environmental control," according to Architectural Record.
