riazzi substation architectural façade : pittsburgh, pa
dynamic skin elevates resilient infrastructure
Client: Public Utility
The project elevates the presence of a new electrical substation serving Oakland, one of Pittsburgh’s most vibrant neighborhoods, as it continues to grow. Located along an urban trail popular with pedestrians, cyclists, and cars, the site is adjacent to world class universities, hospitals and cultural institutions, expansive parks, and a dense, dynamic residential community. The client engaged PWWG to design the façade, challenging the typical typology of utilitarian infrastructure, and embodying their mission to energize the community.
Collaboration With Stakeholders Created Agency & Refined Design
- PWWG facilitated engagement with five stakeholder groups to gather ideas, nurture support for the process, and refine the design incrementally. 3D models and walkthroughs illustrated options.
- Final concept expresses “motion” with 600 twisted aluminum fins secured vertically at different angles to the entire precast concrete façade. The play of shadow, light, and color on the fins as they twist creates depth and the illusion of undulating waves. The fins seem to move as a person travels along the façade at different speeds, with a unique experience on foot, by bike, or by car.
- Materials and detailing achieved the client’s safety and operational needs, and their goals for constructability, durability and cost. Muted greens and blues of the fins blend with the greenery of the adjacent hillside. Density and precise placement of the fins conceals the concrete substation and its scattered mechanical penetrations behind a cohesive, dynamic façade. Panelizing the fins allowed for modular, efficient installation.
- The project invests in the neighborhood with an eye-catching, instantly iconic new civic element that reflects the unique character of the community.
