Proj Overview

Project Overview

The precast concrete panels are exposed on all facades except on the north side, where the panels were covered with charred-cedar siding and backlit with metal mesh. The combination of materials created a layered effect that gives the building depth and offers contrast between hard and soft, light and dark. The detailing reveals the mesh and siding as thin skins against the mass and permanence of the precast concrete panels. Color-changing night lighting enhances the effect.

The interior sides of the precast concrete, along with the building’s steel frame, were designed to be left exposed, juxtaposing them against selected refined elements, such as the reception desk and the frameless glass in the lobby. Backlit graphic panels accent the space.

Precast Solution

Designers acknowledged the nature of the project by using insulated and solid architectural precast concrete panels to create an articulated, high-tech exterior shell. 35 load-bearing, insulated precast concrete composite sandwich panels were used for the walls of the broadcast studios, while 57 panels were used to construct the non-studio exterior walls.

The insulated panels were chosen from both a first-cost and life-cycle-cost standpoint. They provide continuous insulation and high thermal mass while offering durability, quick erection, and low maintenance.

The panels also provided the monolithic appearance designers wanted without any thermal bridging. The composite construction and inherent mass of the precast concrete panels also helped achieve the required sound transmittance reduction needed for the broadcast studios.
