The document discusses different types of lightweight cladding systems for building exteriors, including: - Metal cladding such as continuously supported sheet metal, profiled cladding, and composite panels. Examples given include the Jewish Museum in Berlin and Guggenheim Museum. - Rainscreen cladding systems which use open joints and drainage planes to allow water to escape. Examples include Bridgewatchers House and the Lock-keeper's Graduate Centre. - Mesh screens made of materials like stainless steel that can be integrated with lighting or photovoltaic panels for aesthetic and functional purposes. The T-Mobile headquarters and Marina Bay Sands Hotel are discussed.

Cladding
What is “Cladding”?
“Cladding” is a word used to
described non-loadbearing external
walls in buildings.
This clearly distinguishes cladding from
load bearing external wall systems,
which form an integral part of the
building structure.
Cladding systems are fixed back to
the main structure of a building, but do
not contribute to its structural integrity.

27. The T-Mobile headquarters in Bonn, Germany,
uses a metal mesh facade that integrates LEDs
to produce an ever-changing media landscape.

28. Mediamesh has two functions, to be
transparent during the day to allow sunlight
to illuminate the interior office space and
equally so, to transmit day or evening a
video image across the front of the building.
The sleeves are holders for a series of
'transparent aluminum profiles filled with
RGB LEDs and covered to with a waterproof
resin. Can also be integrated with
photovoltaic panels

External facade of the Marina Bay Sands Hotel
is the small stainless steel "leaves" that flutter
like a digital equalizer and looks even more
beautiful when it creates ripple-like effects.
