Cladding Systems
Adaptive Solar Facade (ASF)
The envelope is not a passive barrier, but an adaptive, active, and
sensible layer between the exterior and interior environments. The
focus of these adaptive facades is to deal with multiple
requirements such as mitigation of environmental impacts, saving
and harvesting energy, and much more. With their adaptive
characteristics, these facades work towards improving building
performance by enhancing daylight utilisation, reducing cooling and
heating loads, generating electricity, and fine tuning different
activities. In simple words, an adaptive PV façade is a photovoltaic
system mounted on a façade capable of integrating the benefit of
integrated solar tracking with that of adaptive
shading.Building-integrated photovoltaics or BIPV is suitable for use
in all parts of a building envelope including the skylights, shades,
roofs, and facades etc.
Mashrabiya solar
responsive screen
Mashrabiya is traditional Islamic window element with its characteristic
latticework is used to cover entire buildings as an oriental ornament, and a
sun-shading device for cooling. Designers have reinvented this vernacular
Islamic wooden structure into high-tech responsive daylight systems – often
on a massive scale and using computer technology – not only to cover tall
buildings as an oriental ornament, but also as a major responsive daylight
system.
The current renaissance of the mashrabiya culminates in a large-scale
responsive screen system in Abu Dhabi with the Al Bahr Towers by Aedas.
The solar-responsive dynamic screen decreases the towers’ solar gain.
According to Aedes, the lightly tinted glass reduces the incoming daylight at
all times and not only for temperature-critical situations. The system even
includes about 2.000 umbrella-like modules per tower driven by photovoltaic
panels.
Kinetic Wind powered Facade
Artist Ned Kahn teamed up with Urban Art Projects (UAP) and
designed a kinetic, wind-powered façade for a short-term car park at
the Brisbane Airport. No less than 250,000 aluminium plates were
installed over a substructure, providing a kinetic shading system for
the interior. The 53,000-square-foot surface moves with passing
wind and creates ever-changing patterns that resemble the rippling
of a disturbed water surface.
Acts as a direct interface between building and environment. The
feature is elaborated with fluttering lines from the surface of the
brisbane river. inside the car park, intricate patterns of light and
shadows are projected onto the walls and floor as sunlight passes
through the external panelling system. this provides practical
environmental benefits such as shade and natural ventilation for the
interior space of the lot.
Optical Glass Facade
Sunlight from the east, refracting through the glass, creates beautiful
light patterns. Rain striking the water-basin skylight manifests water
patterns on the entrance floor. Filtered light through the garden trees
flickers on the living room floor, and a super lightweight curtain of
sputter-coated metal dances in the wind. Although located downtown in
a city, the house enables residents to enjoy the changing light and city
moods, as the day passes, and live in awareness of the changing
seasons.
6,000 pure-glass blocks (50mm x 235mm x 50mm) were employed on
this facade. 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.
Single Pane Glass
The facade is made of single panes of glass spanning from floor to ceiling, fastened to the structural system by steel mullions

Bridger Steel's 7.2 Structural Box Rib Panel System
Bridger Steel's 7.2 Structural Box Rib Panel System combines industrial aesthetic
with heavy-duty structural integrity. Use as roofing or siding to complement any
project. Homeowners and designers love this modern design as a vertical or
horizontal wall panel. It has also been used effectively as wainscoting or interior
accent.

Bam South
286 Ashland Place, Brooklyn, NY 11217
Finished Cladding Materials: Aluminum Composite Material (ACM) and
Crystalline Glass Stone
System Type: Rainscreen with Gasketed Mega-Panel Joints
Description:
According to architect Ten Arquitectos, this mixed-use building will serve
as the gateway to Brooklyn Academy of Music and the newly developed
cultural district. Comprised of approximately 220,000 sf of ACM and
nearly 16,000 sf of crystalline glass stone, the complex geometry of the
façade was achieved through 3D modeling and highly skilled craftsmen.
Because the exterior walls were manufactured as panels in a climate
controlled facility, EEWS was able to ensure a high level of precision and
quality demanded by such a high-performance application.

RAINSCREEN SYSTEM
Shanghai Tower
the major structural system of this building is the
internal concrete core wall and outer mega frame
system. Outside the main structural system, there is
another secondary cladding system to support the
curtain wall, which is directly connected to the mega
frame. Shanghai Tower has the tallest mega frame
structure in the world and the largest and highest
flexible curtain wall in the world. Strictly speaking,
Shanghai Tower and China Zun are not pure mega
frame structures, as they have massive core wall
works as part of the lateral stability system. This is
different from the HSBC headquarters in Hong
Kong, which solely relies on the mega frame to resist
both lateral load and gravity load.
Metal Cladding
Alucobond PE, the original ACM, consists of two
sheets of smooth .02-inch aluminum
thermo-bonded to a polyethylene core in a
continuous process. In other words, it’s made of
super-thin aluminum panels that are extruded and
combined under high pressure with plastic —
hence the malleability. Alucobond PLUS is the
brand’s ACM that’s best for buildings with higher
fire safety regulations. Alucobond® Axcent is also
offered for any project that needs a painted metal
trim.
the company uses these methods to manage any
moisture that infiltrates the wall cavity of a
building. Such cladding also improves the thermal
efficiency of the overall structure. So, yes, it’s
mostly waterproof and an amazing conductor of
heat. At first glance, metal cladding may seem
solely aesthetic, but it’s also sustainably
functional.
Two thousand triangular pixels make up the skin of the curved exterior façade and catch
the sun at different angles throughout the day, creating a prismatic effect.
Route and Return Wet & Dry Seal
1. The Route and Return Wet Seal method is the most economical way to
install Alucobond. The setup is simple: A silicone sealant is placed between
each panel as an air and water barrier, then basic male/female clips simply
attach the cladding to the building — no matter the size, shape or complexity
of the panel designs. There’s one problem with this method, however: It leaks.
2. The Route and Return Dry Seal method is a little less messy. It requires
gaskets to be inserted into the joints between the panels instead of the silicone
sealant. This allows the façade to stay much cleaner over time. The system
also features continuous extrusions around each panel to enhance structural
integrity and act as a secondary gutter system. But this method often causes
concern over the durability of the gaskets.
