LEED Platinum Certified, the Tower at PNC Plaza is an 800,000 square feet headquarters for the PNC bank in Pittsburgh, Pennsylvania. Planned as a landmark building, both with regards to design and in terms of environmental friendly solutions, the 33-story (545 feet) tall tower was estimated to cost $400 million when announced in 2011. Incorporating state-of-the-art green technology, including a double-skin facade and solar chimney, the building was designed to exceed LEED Platinum certification and to be the greenest office tower in the world.
WindowMaster has delivered more than 6300 actuators to control 700 parallel windows in the outer double skin façade and 1450 automated air vents in the inner facade.
From its one-of-a-kind, breathable double skin to its innovative workplace strategy, The Tower drives performance to new levels. The building “breathes” with a double-skin facade: A natural ventilation system that has a glass outer weather and air barrier and an inner layer with automated air vents, and manually operated sliding doors. A series of automatic sensors on both layers open up the building for air when the weather permits. An innovative solar chimney creates a stack effect through the core of the building to ventilate excess heat without the need for mechanical ventilation.
The main reason for choosing WindowMaster as a supplier for this project is the MotorLink® technology that enables genuine synchronization of four actuators on one parallel window and exact position control and feedback via the BACnet BMS.
“The research told us that 45% of the time we would be able to open our windows for fresh air and essentially turn off the mechanical ventilation in the building. We had to create a double skin that operated through a building control system that would open during the optimal weather days…”
