Facilitating the ventilation are pop-out windows (located in the exterior façade) and vents (located in the interior façade) to allow fresh air into the building—and a solar chimney. “The owner, design team, and the contractors worked together diligently to optimize its sustainable footprint.”. Energy Responder: The design integrates passive design strategies and systems. Subscribe to the FREE Digital Edition of Modern Contractor Solutions magazine. Simple Solution for Accurate Level and Slope. For nearly half of the year, during spring and fall, the building ventilates as fresh air flows through actuated vents in the exterior façade, into the space between the curtain walls, and through two vertical thermal shafts and a solar chimney, warming or cooling the interior space passively. The building’s interior was designed as a vertical campus to promote connectivity and Paladino was instructed to push the boundaries of the approach beyond LEED, which is exactly what we did. Further, the design team analyzed the content, origin, and embodied energy/carbon of materials to select specific building materials. We link existing real estate operations with company values, bringing the brand story and promise to life through each company's sustainable built environments.

Extruded insulation provides the body of the unit, sized to maximize the thermal performance of the assembly, with top and bottom fire-plates for a 2-hour fire rating. Project Owner: The designers specified Schöck Isokorb® Type CM structural thermal breaks (STBs) for cantilevered concrete slabs. Dick (general contractor), Buro Happold (MEP), Performance Rating: And then the firm compiled all the ideas together into the Tower at PNC Plaza, which opened last October. Warm or cool water is supplied in tubes embedded in the concrete floor.

Benedict Tranel, principal at Gensler Architects and Project Architect on the Tower, says, “The inner façade of the building is like the insulation layer in a jacket while the outside glass façade is like the outer GORE-TEX® fabric layer.” Hao Ko, design director of Gensler Architects, adds, “Without the thermal breaks it would be like wearing a down jacket but leaving it unzipped.”. Radiant Floors: To efficiently maintain interior comfort in large spaces, the Tower’s lobby and indoor park feature a radiant floor that both heats and cools.

The Tower at PNC Plaza is the LEED Platinum certified commercial office headquarters for The PNC Financial Services Group. STBs contain upper tension bars, bent shear bars, and lower compression modules for structural support. Kim Lyons. During summer, solar shades installed in the glass curtain walls inhibit the amount of solar energy transferred into thermal energy (i.e., heat, inside the building). For instance PNC committed to using local materials, so recycled-content Pittsburgh steel was the obvious choice for the base structure. The building’s ventilation can be set to an automated system or altered manually. A double-walled breathable façade provides a thermal buffer while allowing air to pass through, and a narrow floor plate permits maximum daylight penetration. Proprietary research and company-specific observations informed the workplace Type CM structural thermal breaks (STBs) for cantilevered concrete slabs. About 2,500 temporary construction jobs were created as a result of this project, and nearly 20 percent of the tower’s construction budget went to women- and minority-owned contractors. ...
