Copper Architecture Forum 2013
COBRE INCOMPARABLE
Este nmero invita a las comparaciones tanto sobre cmo
los arquitectos abordan el diseo de sus edifcios como de
su actitud hacia el cobre como un material arquitectnico
moderno.Es ascinante ver cmo tres importantes estudios de arqui-
tectura han tomado enoques muy dierentes para una misma
tipologa de edicio (el museo), y han hecho un uso igualmente
distinto del cobre y de sus aleaciones para caracterizar sus
diseos. En Varsovia, Lahdelma & Mahlamki exploran la
translucidez de la achada, con el cobre prepatinado aadien-
do un luminiscencia verde para su arol en el parque (pgina
24). En contraste, Foster + Partners en Munich modulan las
achadas con una rejilla de barras verticales situadas delante
de planchas cncavas, todo en una aleacin dorada de cobre
(pgina 28). Por ltimo, el proyecto de Staab Architekten en
Ahrenshoop se dene por las ormas de un edicio tradicional,
envueltas en planchas de complejos perles de latn.
Tambin resulta interesante comparar cmo se ha utilizado el
cobre en dos edicios dierentes diseados por el mismo estu-
dio de arquitectura Wilkinson Eyre (pgina 16). Aqu, el cobre
orma parte de la selecta paleta del arquitecto, compuesta por
materiales ligeros y que evolucionan de orma natural.
En su conjunto, estos proyectos ejemplican una creciente diver-
sidad de diseos innovadores con cobre, aprovechando al mximo
sus caractersticas nicas. Adems de la riqueza visual y la liber
tad de diseo, tambin merece la pena recordar el incomparable
rendimiento del cobre y sus credenciales verdes - incluyendo una
total reciclabilidad, destacada en el ltimo artculo de este nme
ro (pgina 38).
Pero primero, os presentamos los diez proyectos nalistas de
los Premios Europeos del Cobre en la Arquitectura de este ao,
elegidos por un jurado de arquitectos de entre los 82 proyectos
inscritos.
La decisin del jurado sobre los ganadores de los Premios se
anunciar el prximo noviembre en la eria internacional BATI-
MAT que se celebra en Pars. No obstante, puedes comparar los
proyectos y darnos tu opinin votando en nuestra web (ms inor-
macin en la pgina 4). Y, por supuesto, esperamos que te unas

ALPINEAESTHETICUlla Hell o Plasma Studio discusses the use o ormand geometry in the design o this hillside apartmentbuilding in Sesto, Italy, to refect regional topographyand redene the local vernacular.
Located at the edge o a residential area in the Dolomites, the buildingsmass was, in part, determined by the unctional elements required to
host six independent apartments with underground parking and a com-
mon circulation core. A ormal incision marks the main access and the
division o the units, splitting the main volume in two halves. Apart rom
its unctional connotations, this incision becomes the defning element
o the building. From either side o the cut, strips unold to orm the bal-
ustrades o generous covered balconies that merge with the surrounding
topography. Following the steep natural hillside with each oor, the strips
and the aade jump back.

12 COPPER ARCHITECTURE FORUM 35/2013
All six, generous holiday homes are orientated
to catch the southern sun and panoramic view
o the Dolomites. The design maximises privacy
through both the splitting o the building volume into two
parts and the stepped balustrades, which block views o
each terrace space rom the unit above and rom passers-by.
Every apartment enjoys an extension o the internal living
area through a covered, sun- and view-acing terrace which
terminates in a small private garden.
The residential area location has a very eclectic appearance.
We responded by generating a volume which grows naturally
out o its surrounding topography and blends into it by limit-
ing the material palette to a very local almost vernacular
code comprising larch wood and pre-oxidised copper. Both
the copper and the larch wood are subject to natural change
in colour through the atmospheric inuence o sun, rain and
snow. By borrowing rom the colour palette o nearby arm-
houses with their dark, sunburned larch wood aades, the
building blends into its natural surroundings. This local larch
wood is used to defne both internal and external living areas.
South acing oor-to-ceiling glazing maximises views and
winter solar gain, whilst external brise soleil and the bal-
cony overhangs minimise overheating during summertime.

The main circulation a continuation o the ormal incision
is very compact and repeats the use o the local larch woodrom the aade. Particular care was taken with the design
o the copper balustrades, which stem rom the natural
topography and wrap around to meet the building at the
central incision, then peel o again and end once more in the
surrounding landscape. When peeling o, the metal sheets
divided into horizontal strips describe a curved, hyperbol-
ic-paraboloid geometry. Here, the cratsmans expertise is
showcased to its ull extent.
The dark, pre-oxidised copper surrounds the volume rom all
sides. The copper strips orm a second skin, o ering shelter
and defning the roo as a continuation o the overall aadeand building volume. The orm o the roo itsel draws on a
local planning regulation demanding only a pitched roo or
this specifc building plot. Reinterpreted, it became part o
our design concept, reerencing the traditional pitched roo
typology not through replication but, rather, by exploring
its hidden potential.
The restrained material palette carries through rom outside to interior spaces.

A BIGGER SPLASHWilkinson Eyre Architects describe the recently completed
Splashpoint Leisure Centre, which creates an important new
public acility in a distinctive copper-clad building overlooking
the sea in Worthing on the south coast o England.

www.copperconcept.org
We were appointed to design this new swimming pool or Worthing
Borough Council ollowing a hotly contested RIBA competition that
attracted over 400 entries. The new complex, located close to the town
centre, is an exciting development on a unique searont site. The new pool com-
plex includes a six lane, 25 metre pool; a combined learner/diving pool; indoor
leisure pools with rapids, umes and outdoor waters; a health and ftness centre;
ca; crche and exible space or other activ ities.
Our design maximises the potential o the site with ribbons o accommodation
owing rom north to south to emphasise the connection between land and sea.
Each pool orm has its own terrace, opening up the aade to animate the beach-
ront elevation and enlivening this prominent location in line with the Councils
aspirations or an Active Beach Zone.
The dynamic, ragmented shape o the new leisure centre is arranged to respond
to the surrounding mix o built orms and landscape. The buildings dramatic
sawtooth roo, with its ranks o sinuous ridges, recalls a series o dunes that
curve and twist towards the coast. This shape reduces the visual mass o the
buildings and mediates the change in scale rom the terraced houses that line
the coastal road to the expansiveness o the open sea.

Worthing is one of the most quintessential English seaside
towns, a place with an interesting history and a fantastic
seafront. Our ambition was to design a building that carefully
responded to these surroundings, creating a structure that
has both a human and civic scale. Our building seeks to draw
on forms already present in the town, taking on the undulat-
ing linearity of the ranks of surrounding terraced houses andthe breakwater groynes on the beach. The building occupies
a prominent location on the seafront, but rather than domi-
nating the site in the style of a grand seaside pavilion, it sits
informally, even playfully, within its setting.

Sel-fnished Natural MaterialsThe structure is clad in copper and red cedar a palette o
sel-fnished natural materials selected to age graceully in
the maritime conditions. The aade integrates a series o sub-
stantial glazed panels, creating the eect o picture rames
to the windows and roo-lights. Copper and timber are materi-
als that are synonymous with the tradition o English seaside
culture. These materials are also robust against the ferce
coastal elements, complement each other aesthetically and
are sensitive to the history o this beautiul seaside town.
Copper is a material that truly roots itsel to the
site; the material metamorphoses rom its tradi-
tional rich, reective copper red through
to the dull dark browns and urther
to a vibrant green patinated fnish.
Two dierent fnishes have been
used to create variation along the
length o the western aade: the
primary wall and roo suraces
use at cladding panels and the
projected windows use a per-
orated rain screen system.
From the inside, the building is emphatically ocussed towards
the sea. The spans between the longitudinal ridges o the roo
widen as the height o the building increases, running towards
the sea and terminating in a series o glazed acades that di-
rectly overlook the water. The building has been raised so that,
rom pool level, there is a powerul v isual connection between
the pool and the sea, creating the impression o an infnity pool.

the University o Exeter, characterised by a soaring timber-ramed,
ETFE and copper roo as the architects explain.

The Forum links essential acilities such as the Great
Hall, lecture theatres and the Student Guild along a
galleried, indoor high-street lined with caes, a shop
and a bank. A student services centre takes a prominent po-
sition within the new building, broadening and enhancing the
range and availability o pastoral services that the University
oers. A newly built state-o-the-art auditorium, speciallycommissioned public art, landscaped open spaces and reur-
bished library complete the Forum, making it the heart o the
social and academic lie o the University.
The starting point or our design was the natural eatures o
Exeters amously hilly Streatham campus. The orientation
and arrangement o the building and its adjacent landscaped
piazzas respond to the contours o the hillside setting, which
are traced by a green corridor the main pedestrian route
through the scheme. The steep topography o the hillside has
been rationalized into two circulation levels that connect the
Library and the Great Hall, uniying two vital centres onceseparated by a steep slope.

COPPER IN PRACTICE
Beneath the roo and behind the glass acades that enclose
the space between the existing buildings, the Forum is an
airy, galleried hall which shelters and unifes a series o new
student-ocused spaces. The upper level gives access to the
Great Hall, Student Guild and a new suite o learning labs
and seminar spaces designed or Harvard-style exploration
sessions. The Forums vertical arrangement unifes the two
circulation levels o the plan, creating new accessible routes
that make the campus more legible and easier to get around.
At ground level, the green corridor runs through the build-
ing, creating a covered high street with a bank, shops, caes,
breakout spaces and access to the library, student serv ices
centre and auditorium. The auditorium is a new building also
designed by Wilkinson Eyre providing a 400-seat lecture
theatre with state-o-the-art equipment and seating, and
spectacular views out to landscaped lawns.
Column-ree Floor Area
The Forums roo encloses 3,500 m2
o airy, column-ree oorarea making it one o the largest timber roos o its kind. Its
owing orm contrasts with the orthogonal brick architecture
o the existing campus, responding to the hillside setting and
preserving key views across the city to Dartmoor. Beneath the
roos copper cladding, which will graceully develop a green
patina over the next 15 years or so, lies an innovative hybrid
timber structure. A matrix o timber members joined at steel
nodes emulates the traditionally all-steel construction o a
grid-shell roo, weaving between the existing buildings o the
campus.
The triangular cells o the grid are either clad in copper, withoak-slatted acoustic baing on the interior surace, or flled
with ETFE pillows which ood the loty interior spaces o
the Forum with natural light. Smaller panels o conventional
glazing are used in the roo windows above teaching areas to
mitigate any possible noise caused by alling rain.
Sustainability CredentialsThe Forum was designed to achieve a BREEAM excellent
rating. While the sustainability credentials o the timber
structure and copper cladding are apparent, other eatures
such as natural stack ventilation, a labyrinth pipe air-cooling
system and energy efcient lighting maximise the environ-
mental perormance o the main building in use.

ILLUMINATINGCOPPER
The recently completed Museum othe History o Polish Jews in Warsaw
is dened by a layered, transparent
aade design using pre-patinated
copper in dierent orms, combined
with decorated glazing.
The new buildings design, by Lahdelma & Mahlamki
(working in conjunction with Kuryowicz & Associates
in Poland), stems rom the architects 2005 competi-
tion-winning entry. The Museums location in Warsaws Willy
Brandt Park is signifcant, as it was part o the Jewish ghetto
during the war, and the design relates closely to the adjacent
memorial to the uprising in the ghetto. However, it is not
seen as a museum o the Holocaust but rather a celebration
o 1,000 years o shared history. The Museum will act as a
multiunctional centre or research and exhibition o Jewish
heritage, education and culture.
A Shimmering Green LanternConceived as a simple box, the competition design envisaged
a lantern illuminating its park surroundings. The designers
solution is a regular grid o vertical, alternating glass and
copper panels, saw-toothed across all our acades, in ront
o a corrugated copper backdrop. This animates the building,
presenting varying degrees o transparency and changing
eects rom dierent viewpoints. In sunshine, the gossamer-
like glass panels shimmer with a copper green hue. At night,
the lantern concept is realised by the play o advanced LED
lighting behind the decorated glass onto the green corru-
gated copper.

The sharp, engineered rhythm o the copper and glass saw-
toothed acades contrasts with a sculptural, curvilinear
entrance. This opens into a cavernous hall space almost
an internal biblical landscape symbolising the parting o
the Red Sea and deliverance o the Jews rom Egypt. A gentlysloping bridge, oating above the permanent exhibition be-
low, brings visitors into the central hall which leads through
the building, terminating at a massive, glass wall overlooking
the Ghetto Heroes monument.
The curved, polished concrete walls rise up some 20 m
creating animated, organic orms that embrace the space.
The main hall is the most important element o the scheme,
intended as a pure and silent space, introducing visitors to the
museum. The building also provides an auditorium, cinema,perormance hall or fve hundred visitors, an educational
centre, club, restaurant and ca.

GOLDENTRANSFORMATIONFoster + Partners explain their major project to transorm
the experience or visitors to Munichs Lenbachhaus Museum,
where a golden copper alloy intervention enhances the distinc-
tive, ochre coloured acades o the original building.
The Museums historic buildings have been careully restored and the ex-
hibition spaces augmented by a spectacular new wing. As well as radically
improving the buildings environmental perormance, the remodelling hascreated a new entrance and social spaces, including a restaurant, terrace,
education acilities and a dramatic ull-height atrium, where the old is ar-
ticulated within the new.
Built in 1891 as a studio and villa or the ar tist Franz von Lenbach, the
Lenbachhaus Museum has been gradually extended over the last century.
However, its buildings were in need o renewal and the museum lacked the
acilities to cater to a growing audience o 280,000 people a year. Redefn-
ing circulation throughout the site, the project has transormed a complex
sequence o spaces o dierent periods into a unifed, legible museum that
is accessible and open to all.

Our main challenge has been to maintain the same amount of exhibition area,
within the museums footprint, while creating new circulation and v isitor
spaces. Given the way that the different parts of the museum had evolved,
there was no such thing as a typical space every corner is unique and requiredindividual attention and different design decisions. This has been a fascinating
process. Another important aspect of our design has been creating new oppor-
tunities for works of art to be exhibited outside the traditional confines of the
gallery, such as in the atrium. This space develops the idea of the urban room
it is the museums public and social heart, and point of connection with the
wider city.

Complementary Copper Alloy InterventionPeeling away the unnecessary historical accretions, a 1972 extension
has been removed to reveal the wall o the original villa, which has been
sympathetically restored in ochre render. The dierent historical ele-
ments are then unifed along Richard-Wagner Street by a new gallery
pavilion, containing two levels o exhibition space. The new building is
intended as a jewel box or the treasures o the gallery it is clad in
metal tubes o an alloy o copper and aluminium, their colour and orm
designed to complement the villas rich ochre hue and textured acades.
Inside the new building, a sequence o intimate galleries display
the Museums internationally renowned Blue Rider collection o early
twentieth-century Expressionist paintings, echoing the domestic scale
o their original setting in the villa Lenbach. As many o the works o art
were painted in plein-air, indirect natural light has been deliberately
drawn into the upper level galleries to create the optimum environment
or their display.
A new entrance has been created adjacent to the restaurant, ac-
cessed via a new landscaped piazza to the east o the museum this
move reclaims the courtyard garden, turning it rom a pedestrian
thoroughare into a tranquil space or visitors. The restaurant is open
outside o the Museums opening hours and its seating continues
outside, helping to enliven the surrounding streets and attracting new
visitors into the galleries.
The new social heart o the building is a dramatic top-lit atrium, with
ticket and inormation desks, access to a new temporary exhibition
space on the ground oor and a grand, cantilevered stair to the upper
level galleries. Clearly articulating the old within the new, its impressive
volume incorporates the ochre
exterior wall o the original villa
and is scaled to accommodate
large-scale works o art. The
Museum commissioned the
artist Olaur Eliasson or a site
specifc work titled Wirbelwerk.
During the day, sunlight washes
the white walls via a long, slen-
der opening at roo level and
horizontal louvres cast chang-
ing patterns o light and shade
within the space.
As well as repairing the abric o the existing buildings, one o the
main aims o the project has been to radically improve the museums
environmental perormance. A water-based heating and cooling system
within the oors has been implemented using signifcantly less energy
than an air based heating, this represents an innovative step in a gallery
context. Rainwater is also collected and recycled and lighting has been
replaced and upgraded with low-energy systems.

Ahrenshoop - located between the Baltic Sea and the salt marsh
coast o Germany - is historically important as a ormer artists
colony and, today, is well known as an attractive tourist destina-
tion. The new Kunstmuseum Ahrenshoop will house works o art
created locally over the years that display an intense connection
with the landscape. The new building itsel is destined to become
a signifcant landmark and a magnet or the many visitors who,
especially in summer, pass through the isthmus near Ahren-
shoop heading or the string o islands o the coast.
Staab Architektens design was inspired by an old photo o theregion, showing an irregular grouping o similarly shaped,
traditional, buildings - obviously a armstead characterised by
steep thatched roos. From this image, the architecture o the
new museum developed rom the local agricultural vernacular,
resonating with the exhibited artists strong local connections.
A cluster o housesThe result is a homogeneous ensemble o fve, largely window-
less, single-room buildings with hipped roos virtually cut o
below the ridge-line a dev ice that enables the internal exhibition
spaces to be naturally lit. The individual houses, constructed
entirely rom reinorced concrete, are clustered together as ina traditional village - ace dierent directions and are interlinked
by a central at roo at their eaves. The entire complex is de-
signed as a sculptural whole with a central oyer rom which the
individual exhibition spaces can be accessed.
From the outset, the architects sought a modern interpretation
o the reed thatch used to cover traditional buildings to clad the
new museum. A sustainable copper cladding was avoured as
it naturally exhibits similar ageing properties. Ultimately, brass
was chosen to exhibit colour changes resulting rom oxidisa-
tion mirroring those o traditional thatch. Initially, the brass is
reminiscent o a reed-covered roo glowing in the sunlight. Likethe reed, the metal will gradually change with shades o greenish
brown, through grey-brown to dark brown-anthracite, caused by
the ormation o a natural protective layer that guarantees the
resistance and longevity o the material.
In this new museum, Staab Architekten introduce
modulation and complexity with a proled brass
covering a contemporary take on reed thatched
roos enveloping a cluster o distinctive orms,
reminiscent o local rural buildings.

COPPER IN DETAIL
Animated profled surace structureBut the architects went a step urther with their analogy,seeking a surace orm resembling reeds to act as the
buildings skin. This involved a patented process and close
collaboration with specialist metal orming company MN
Metallverarbeitung Neustadt. A unique sheet profle was de-
veloped that exhibits the depth and complexity o a thatched
surace on the preabricated brass acade.
The apparently random, animated profled surace structure
ows continuously with no visible oset even in the transi-
tion where the eaves meet giving the impression that the
whole has been cast as one piece. The variations o light and
shadow on the edges and curves o the brass surace allowthe cladding to change in alternating shades, already sug-
gesting how the colour o the surace will alter over time as
a result o oxidisation.

Copper Recycling
Closing the Loop
Copper is one o the most valuable materials in mod-
ern construction. This value results in the high level o
recovery o copper which, in turn, can be recycled or
building applications including roos and acades. Ac-
cording to the International Copper Study Group (ICSG)
overall 41.5 % o the copper used in Europe in 2011 came
rom recycling. Although this rate has been stable or
the last decade, the 2012 estimate o 44 % reveals that
our copper requirements will increasingly be met by re-
cycling in uture. The physical nature o copper means
that it can be recycled again and again without loss o
perormance and copper products or construction can
be made o up to 100 % recycled copper content.
For building construction, the demand or 100 % re-
cycled content is also increasingly being satisfed,
as suppliers receive more materials back rom the
recycling chain. Selective dismantling or building dem-
olition or reverse-construction rom roo to oundation
can result in closed loop recycling. Most o the recov-
ery processes are done manually and although this is
not the astest method, it is the most efcient. Ater-
wards, in partnership with their architectural copper
suppliers, architects can ensure that the copper taken
rom the building site is transormed into new copper
or use in their regeneration projects. The ollowing two
case studies demonstrate this closed loop recycling ap-
proach.
The red metal is used or its intrinsic qualities o electrical and
thermal conductivity, corrosion resistance and workability in the
building construction sector. In Copper Forum 34, you read that
environmental reporting requirements in the building sector are
also steadily increasing. One o the real sustainable benets o
copper is that many o the copper and copper alloy products used
in plumbing, heating ventilation and cooling, solar thermal instal-
lations and architectural applications, can be produced with 100 %
recycled content.

Renovation o this 12,500 m2, typical midtwentieth cen-
tury styled civic building included re-cladding using the
very same copper material originally installed in the
1960s an impressive demonstration o the extreme-
ly long-term value o copper as an asset to buildings.Technically, there was nothing wrong with the original
copper but moisture ingress and a lack o thermal insu-
lation created some problems or the owners. Around
70 tons o copper and 10 tons o brass were stripped
and taken back to the original supplier who recycled it
back into replica parts or the restoration o the build-
ing. Samples or the new cassettes and trim were taken
rom the dismantled aade and were aithully repro-
duced.
Pre-oxidised copper, giving a warm shade o light
brown, was used throughout the project. Copper has
been re-used here in a versatile way rom cornice tobase. The aades now consist o the original brick wall,
contrasting with proled copper panels and protrud-
ing pilasters. Major savings resulted rom this process
both in nancial and environmental terms. This clear-
ly demonstrates how the whole lie cost o a project
needs to be considered and how copper can save em-
bodied energy or carbon ootprint i correctly managed.
The County Administrative Building in Turku, Finland
St Michaelis Church, Hamburg, Germany
The re-roong o the church roo o St Michaelis Church
in Hamburg was necessary because the previous 72
cm wide copper plates were too large to withstand the
suction orces o the strong local winds. This was par-
ticularly true in the lee o the tower, where the copper
sheets were coming loose and even threatened to fyaway in a storm. A technical assessment o the copper
roo was carried out and recommended replacing the
old roo with new, smaller (52 cm wide, 0.7 mm thick)
copper roong panels that could withstand the wind
suction. A total o 3,250 m2 o copper sheets, weighing
44 tonnes, were installed as part o the restoration pro-
ject.
The old copper was removed rom the site, melted
down, cast and re-rolled into new sheets ready or
installation. Original olding techniques used in the
cladding o the original roo design were used to restore
the roo. The church originally built in 1751 and hav-ing survived a re in 1906 and damage rom the second
world war is today a distinctive landmark in Hamburg
restored to its ormer glory.
