Shadow Box Design

From HOLT Architects:

Our typical shadow box detail specifies a composite aluminum panel for the interior closure material.  We have recently run into issues with the panel deforming and expressing waves.  The theory is that this is due to the interior plastic core of the panel melting.  Allucobond is rated to 170-180 degrees, but due to the dark color that was selected for this project it may have been possible.

In the future, when we design and specify shadowboxes we should simply use a 1/8” aluminum panel with a Kynar finish rather than the composite metal panel option. (see Breckenridge)

Venting of the space between the glass and the panel is also becoming a common practice.  This can be done in two ways:   1. Removing 1” the interior glazing gasket at both top corners of the glass panel in front of the shadow box will let the air space vent into the glazing pocket.  2. Drilling two ¼” holes at the top of both sides of the vertical mullion within each shadowbox will let the air space vent into the vertical mullion.  We should coordinate the preferred method of venting with the approved window manufacturer.

Reveal Switchable Glass: Guardian Interior Glass:
InGlass Berman
HOW IT WORKS - Guardian Reveal uses a low-voltage electrical current to arrange liquid crystal molecules into a pattern that makes glass transparent when turned on. Turned off, the LC molecules revert to a random pattern, diffusing the light and causing the glass to become opaque.

Case Study: The Bullitt Center | 2030 Palette Blog:
The 2030 Palette is a set of distinct actions – or Swatches – for the planning and design of environmentally responsible and resilient buildings and communities worldwide. Our case studies illustrate how a unique palette of Swatches can be applied to create buildings and communities that consume fewer fossil fuels, compliment and preserve sensitive ecosystems, access site renewable energy resources, and can adapt to climatic changes.
Bullitt Center Masonry Floors & Side Daylighting
The Bullitt Center, currently regarded as one of the greenest office buildings in the world, is an exemplary case study illustrating how a palette of design strategies can result in truly dramatic performance outcomes. Located in in the city of Seattle, this six-story office building is on track to be the largest certified Living Building in the world, achieving energy and water self-sufficiency while creating a healthy, net zero carbon, and beautiful built environment.  -- Written by Francesca Desmarais / Architecture 2030

"The North façade is made of laminated glazed panels within the inside layer has been coated with mirror finish (titanium, siliconitride, chrome et siliconitride) A ‘non-crossing’ attachment system holds the glass and leaves the fixing points invisible from outside. The whole set is maintained on mirror polished stainless steel wales of 10 mm sickness and 25 cm depth."

Just posting this because I used to live in this town and I'm glad they got some "architecture", even if it's derivative.  Still nice to look at.

REPOST from http://www.archidesignclub.com

"Optical Glass Façade
A façade of some 6,000 pure-glass blocks (50mm x 235mm x 50mm) was employed. The pure-glass blocks, with their large mass-per-unit area, effectively shut out sound and enable the creation of an open, clearly articulated garden that admits the city scenery. To realize such a façade, glass casting was employed to produce glass of extremely high transparency from borosilicate, the raw material for optical glass. The casting process was exceedingly difficult, for it required both slow cooling to remove residual stress from within the glass, and high dimensional accuracy. Even then, however, the glass retained micro-level surface asperities, but we actively welcomed this effect, for it would produce unexpected optical illusions in the interior space.
Waterfall
So large was the 8.6m x 8.6m façade, it could not stand independently if constructed by laying rows of glass blocks a mere 50mm deep. We therefore punctured the glass blocks with holes and strung them on 75 stainless steel bolts suspended from the beam above the façade. Such a structure would be vulnerable to lateral stress, however, so along with the glass blocks, we also strung on stainless steel flat bars (40mm x 4mm) at 10 centimeter intervals. The flat bar is seated within the 50mm-thick glass block to render it invisible, and thus a uniform 6mm sealing joint between the glass blocks was achieved. The result? —a transparent façade when seen from either the garden or the street. The façade appears like a waterfall flowing downward, scattering light and filling the air with freshness.
Captions
The glass block façade weighs around 13 tons. The supporting beam, if constructed of concrete, would therefore be of massive size. Employing steel frame reinforced concrete, we pre-tensioned the steel beam and gave it an upward camber. Then, after giving it the load of the façade, we cast concrete around the beam and, in this way, minimized its size."
