In a cool blog by architectus they document the use of fin shading elements on their projects.  Check out their other postings as well.  Architectus if your listening, would be great to see the fins working as structural elements (exterior mounted mullions) on the facade.  When components are clipped on they have a habit of clipping off late in the project:

You’ve got to have some Fins

The use of vertical fins is a fundamental part of the Architectus language. Their purpose is often related to solar shading – but never limited to that: fins create order, repetition, rhythm, abstraction and depth; fins change depending on the viewer.

Some examples follow:

At St. Peter’s Middle School, up to three storey tall concrete fins establish a powerful relationship with the school grounds – revealing the structure and providing shelter at the same time.

Fins determine the interface (or filter) between the public realm and the private loggias at Trinity Apartments, and here they are executed in frameless laminated glass. Walking past the building – looking at the façade obliquely – one perceives an ever changing veil constructed of green layers of glass.

Henderson Library

Douglas Lloyd Jenkins comments in his article “In the Western Tradition”, NZ Listener, 2006:

“The challenge in Henderson was not simply to build a library but to build with sufficient presence to suggest the existence of an entire city. Most of the necessary motifs are there, from the open plaza to the impressive façade…. Vertical laminated timber fins – stand in for classical columns … and an impressive roof overhang stands in for the portico of old.”

152 Fanshawe Street is located on a busy intersection; one side faces a major arterial route into the city and the other looks across semi-rural parkland. A series of rhythmic yet playful vertical concrete fins form a strong edge to the street, while light aluminium vertical fins address the park.

The fins at the Telecom Headquarters are anodised aluminium extrusions, which come in three different projections, related with the width of the adjacent glass panel – resulting in a rough textured façade on the perimeter in contrast to the flush glazing to the courtyards.

At Auckland’s Aotea Centre horizontal aluminium fins are arranged in a sheer endless parallel array at the main entrance as well as in an organic organisation reminiscent of a woman’s long hair for the Bledisloe canopy.

“Of course it’s not an Architectus building if it doesn’t have fins.”
