HOOVER GARAGE AT STANFORD UNIVERSITY
The Hoover Garage parking structure is part of the Stanford Hospital and Clinics and was produced in association with Stanford University in California. The Hoover Parking Garage at Stanford University is a 1,100 stall garage which serves the Hoover Pavilion, a new medical office building for the University.
Hoover Garage is an open-air structure which uses a 3/16' perforated and anodized aluminum surface. The back-side of the panels are cut and grooved at each corner of the panel to provide a more defined edge. The panels use a proprietary Drop & Lock panel technology, a feature of the Inverted Seam patent. This allows for flexible design and simple installation. Each panel is hung by inserts into the vertical extrusion.
Mission Bay Parking
Mission Bay Block 27 is a parking structure serving the UCSF community of San Francisco. Featuring a facade by Zahner, the WRNS Studio design is a noted work of architecture for parking structures.Located in the Mission Bay Block 27 of San Francisco, this design by WRNS Studio for Alexandria Real Estate, houses 1,420 parking spaces on seven elevated levels. The structure features a metal screen with perforated imagery of California's redwood forests. This facade was design-engineered by the Design Assist Group and produced by Zahner.WRNS Studio desired an abstract pattern composed of four distinct oval cut-outs. They provided tree imagery and Zahner Design Engineers processed the imagery into the myriad of circular shapes to abstract the form. For the surface, the firm decided on a perforated bronze-anodized aluminum cladding, which covers the entirety of the metal scope for the garage.
Moiré patterns are a unique visual phenomenon resulting from overlapping patterns. While the phenomenon has been explored for centuries, it is a relatively new concept in architecture, arising from innovations in perforated metal over the past two decades.In architecture the effect will most often be seen in perforated metal screens. As a manufacturer of custom perforated metal systems, Zahner has been involved in a number of these types of projects. Using custom perforated metal, we have developed many examples and techniques designed to yield incredible moiré patterns using shadows, light, as well as layered metal screens. In some cases, moiré happens by accident, but more often than not, these moiré effects are by design. As a medium, architectural moire is in its infancy. We'll explore some of the amazing techniques and innovations in moire further down in the post.
Developing the Design for the Hoover Garage
Zahner provided design assist as well as fabrication services to the general contractor Vance Brown Builders. While this was the first time Vance Brown and Zahner worked together, Zahner had a relationship with the architect as well as a well-known reputation for its successful track record on similar projects with WRNS Architects.
In addition to the perforated metal facade, Zahner also provided the vertical structure which allowed the design team to reduce the overall budget without changing the visual aesthetic.
In the original document, there was a vertical steel member between panels. The panels had a complex support system hanging off of the steel, so Zahner engineers introduced a custom extrusion that would reduce the redundancy. The architect selected the look of anodized aluminum extrusion Zahner provided over the painted steel.
Zahner designed, milled, and machined all of the connection points on the custom aluminum extrusions, which were provided to the steel contractor to install prior to installation of the Zahner perforated panels. This improved the aesthetic and durability without adding additional cost.
Owning the aluminum vertical structure also simplified the dual planes of the panel system. Zahner was able to reduce the parts for how the second plane of panels connects to the structure.
The engineers at Zahner and the architects at the WRNS office enjoy an integrated relationship that continues to evolve and push the boundaries of what is possible to design and build with parking structures.
