PKIRJOITUS
Copper Architecture Forum 34, toukokuu 2013
Copper Architecture Forum -lehti kuuluu European Copper In Architecture Cam-paign -kampanjaan. Sit julkaistaan kahdesti vuodessa, ja sen levikki on 25 000.
Lehte jaetaan arkkitehdeille ja rakennusalan ammattilaisille kaikkialla Euroo-passa ja mys sen ulkopuolella seuraavilla kielill: englanti, espanja, italia, norja,puola, ranska, ruotsi, saksa, suomi, tanska, t ekki, unkari ja venj.
Vuonna 1995 ilmestynyt ensimminenKoppar Forum -lehti oli vain nelisivuinen.
MUUTOS JA JATKUVUUS
Aloitamme numeron hyvstelemll lehtemme toimituksen jttvn Lennart Engstrmin.Hn perusti Copper Forum -lehden 18 vuotta sitten ja on ollut avainroolissa kehittmsslehte Skandinavian arkkitehdeille suunnatusta nelisivuisesta ensipainoksesta nykyiseksinelikymmensivuiseksi ja Euroopan laajuiseksi lehdeksi, jonka levikk i on 25 000 kappalet-ta ja jota julkaistaan 13 kielell. oimituksessamme on osattu arvostaa Lennartin viisaut-
ta, intohimoa kupariarkkitehtuuria kohtaan sek lempe mutta vakuuttavaa luonnetta.yskentely Lennartin kanssa on ollut aina miellyttv.Viimeisten 33 numeron aikana on tehty mys muutoksia, kun sek lehden ulkoasua
ett sen sislt on paranneltu vastaamaan arkkitehtien vallitsevia mielenkiinnon kohtei-ta. Copper Architecture Forum -lehden alkuperiset ydinarvot ovat kuitenkin pysyneetsamoina: innostavan nykyarkkitehtuurin esittely sek kuparia ja kupariseoksia hydynt-vn muotoiluun liittyvien ajankohtaisten aiheiden julkaiseminen.
Esittelemme samalla lehden uuden ptoimittajan, Robert Pinterin, sek uudentoimittajamme, arkkitehti Chris Hodsonin. Heist molemmat ovat kuuluneet toimituk-seemme jo jonkin aikaa, ja molemmilla on runsaasti kokemusta arkkitehtuurista ja raken-tamisesta. Koska toimittajamme on mys arkkitehti, voimme peilata tarkasti arkkitehti-lukijoidemme mielenkiinnon kohteita ja kehitt laajempaa yhteistyt heidn kanssaan etenkin yhteistysivustomme kautta osoitteessa copperconcept.org.
Copper Architecture Forum -lehden toimitus pyrkii lytmn uusia trendej japrojekteja yhdistvi linkkej. ss numerossa tulee esille useita teemoja. Yksi teemoistaon kuparisten julkisivuratkaisuiden lukuisat kyttmahdollisuudet. Auringon varjoja javalon kulkeutumista korostavia elementtej on kytetty useissa rakennuksissa. Ratkaisutvaihtelevat reiitetyist kuparilevyist ja -verkoista muotoiltuihin messinkiristikkoihin javeistosmaisiin kaareviin siivekkeisiin. Joissain suunnitelmissa kupari nyttytyy tysinmodernina materiaalina, jota kytetn hydyksi vanhojen usein mys historiallisten
ja suojattujen rakennusten korjausrakentamisprojekteissa. Lisksi kupari saa julkisenroolin suurissa rakennuskohteissa, joiden myt muokataan mys ympriv kaupunki-ymprist.oivomme, ett nautit tmn numeron tarjoamasta arkkitehtonisen muotoilun monimuo-toisuudesta ja laadukkuudesta.

KUPARIKUNNIAPAIKALLARuotsissa Gteborgin Drottningtorget-aukiolla 20
vuoden ajan kyttmttmn ollut postirakennus
muutettiin 500 huoneen Clarion Hotel Post -hotelliksi
nykyaikaisilla lisosilla, joissa kuvastuu eloisan kau-
pungin henki.
Gteborgilainen arkkitehti Ernst Torulf suunnitteli alkuperi-sen rakennuksen vuosina 19181925 manierismin hengesskyttmll tiilt ja kivikoristeita sek liuskekivist tehty
ja kuparisilla yksity iskohdilla koristeltua mansardikattoa.Katto on ajan myt patinoitunut vihreksi. Postirakennus onnykyisin suojeltu kansallismonumentti. Arkkitehtien Semrn& Mnssonin yksinkertaisilta vaikuttavissa suunnitelmissaoli sulkea alkuperinen hevosenkengn muotoinen rakennusuudella lisosalla ja kytt hydyksi vanhan postirakennuk-sen kuormauspihaa. Olemassa oleva rakennus kunnostettiin
ja muutettiin uuteen kytttarkoitukseen sopivaksi senalkuperist ilmett, yksityiskohtia ja suojattua asemaakunnioittaen. Loput pihatilasta otettiin kyttn rakentamal-la alimpiin kerroksiin uusia huoneita. Lasikaton kautta valopsee tulvimaan yleisiin tiloihin.
Kaupungin uusi maamerkki
Pihan sulkemisella saatiin luotua uusi, avonainen julkisivurakennuksen itpuolelle kareplatsen- ja Odinsgatan-ka-duille. Lisosa muodostuu kahdesta siivest, joista toinen on
verhoiltu kuparilla ja toinen liuskekivell. Samoja materiaa-leja kytettiin mys vanhassa postirakennuksessa. Lisosan
ja alkuperisen rakennuksen rystslinja on samalla tasolla.Siipien yhtymkohdassa kohoaa yhteninen torni, jota erottaapystysuuntainen lasikaistale. 13-kerroksisesta tornista ontullut kaupungin uusi maamerkki, ja siell sijaitsee myshotellin toinen sisnkynti. Kultaisella mosaiikilla koristeltuylellinen psisnkynti on nykyisen rakennuksen lnsipuo-lella Drottningstorget-aukiolla.
teksti Chris Hodson
Uusien lisosien ikkunoissa noudatetaan vanhaa vaakasuun-taista linjaa, mutta pystysuunnassa ikkuna-aukkojen vanhaalinjausta on rikottu. Uusi julkisivu muodostuu nelinmuotoisis-ta levyist, jotka on peitetty kuparilevy ill tai liuskekivill seksaumattomalla lasituksella. Asettelu nytt sattumanvarai-selta. Arkkitehtien mukaan selken ja silen juovikkaaseenpintaan on haettu vaikutteita Helsingin Laajasalon kirkosta jasen vaakasuorista esipatinoiduista kuparikaistaleista.
Hotellissa pystysuuntaisuus nkyy levyjen liitoksissa, ja sitkorostavat vrimuutokset risteviss, vaakatasossa olevissakuparilevyiss. Kulmissa on perinteisten kulmakivien (nh-tviss alkuperisess rakennuksessa) muotoa jljittelevtnykyaikaiset ohuet kaistaleet, joissa kupari ja lasitus yhdistyvtlevyjen paksuuden mukaan. Julkisivun kuviointi on jatkuvahuolimatta katolla olevasta aurinkoterassista ja avoimestauima-altaasta.

Runsaat ja elvt kuparipinnat
Arkkitehdit suunnittelivat julkisivun alusta
alkaen ohueksi rakenteeksi tai pllysverhoiluk-si. Toteutukseen kytettiin erillisi levyj, jotkaesivalmistettiin tehtaassa ja asennettiin paikanpll. Levyjen avulla saatiin aikaan raken-teellisista kerroksista erillinen verhoava sein.Nin voitiin hallita yksittisten levyjen muotoilunmonimutkaisuutta erikokoisia lasitusalueita jaerilaisia juovikkaita kuparipintoja koko julkisivunalueella. Tss kytettiin kolmea kaistalepituutta(200, 250 ja 300 mm) ja kolmea kuparin esipa-tinointisvy, jotka saatiin vaihtamalla vihrenvrin mr tummanruskealla taustalla. Nit
elementtej yhdistelmll saatiin aikaan runsas,elv kuparipinta.

Lpileikkaus
Kunnallinen rooli
Clarion Hotel Post sijaitsee aivan Gteborgin keskustassaprautatieaseman ja suuren Nordstaden-ostoskeskuksenvieress. Uusi torni on saanut julkisen roolin kaupunginnkyvn keskipisteen, joka pyrkii yhdistmn toisistaanerilleen ajautuneita alueita. Se on ennen kaikkea samassalinjassa Odinsgatan-kadun kanssa, mik yhtenist kadun
nkym. Lisksi torni nousee vanhan postirakennuksenylpuolelle, ja se nkyy keskusaukiolta ja kaupungin muistatrkeist kohteista.

Mitttmt ympristvaikutukset
Gteborgin kaupungin ympristviranomaisten kanssakytiin suunnitteluvaiheessa keskustelua kuparipinnoiltavaluvan sadeveden vaikutuksista Gtajokeen. Kuninkaal-lisen teknillisen korkeakoulun professori Inger OdnevallWallinder toteutti ympristn seurantatutkimuksen, jonkamukaan jokeen mahdollisesti ptyvn kuparin mr jisi
erittin vhiseksi (160230 g). Kuparin ympristvaiku-tukset ovat nin ollen mitttmn pieni, ja kuparijmtjisivt lisksi todennkisesti kiinni rakennuksen lhelloleviin materiaaleihin. Rakennuksesta aiheutuvia kupari-pstj olisi mys mahdotonta tutkia joesta, jonka mukanakulkeutuu vuosittain 20 tonnia muuta kuparia. Tilannettavoidaan verrata siihen, ett 300 hotellin lheisyydessasuvaa ihmist nauttisi pivittin 2 mg kuparia sisltvnvitamiinitabletin.

Professori Mnssonin haastattelu on luettavisskokonaan osoitteessa copperconcept.org.
HAASTATTELUChris Hodson keskustelee Clarion PostHotel-projektista Semrn & Mnssonarkkitehtitoimiston omistajan professori
Magnus Mnssonin kanssa.
CH: Miten pdyitte mukaan Hotel Post-projektiin?
MM: Rakennuttaja pyysi minua etsimn G-teborgin prautatieaseman lhistlt sijainti-paikan suurelle hotellille. Olin parhaillaansuunnittelemassa toista hotellia ja syventynytrakennustypologian maailmaan. Postira-kennus oli muutettu toimistorakennukseksi1980-luvun loppupuolella, mutta katsoessanisit ajattelin: tm ei ole toimisto vaan hotelli sen nki ikkunajaosta. Rakennuttaja hyvk-
syi ehdotukseni ja suostui loistokkaaseen pro-jektiin, jossa yhdisteltiin uutta ja vanhaa. Siiton nyt kulunut kahdeksan vuotta.
CH: Minklaisia haasteita tunnetun ja suoja-tun rakennuksen parissa tyskentelyyn liittyi?
MM: Aluksi jouduimme tietysti taistele-maan eri viranomaisten kanssa. Rakennus onsuojeltu Ruotsissa korkeimman luokituksenmukaan, joten jouduimme tekemisiin sekpaikallisten ett kansallisten viranomaistenkanssa, mik oli raskasta. Yksi lhtkohta oli,ett rakennuksen ulkokuorta ei saanut muut-taa milln tavalla.
CH: Vaikka teill on kolme muuta toimis-toa, kiinte toimipaikkanne on Gteborgissa.Poikkeaako lhestymistapanne normaalista,kun projekti toteutetaan nin lhell?
MM: oivottavasti ei. Ohitan tmn raken-nuksen kuitenkin pivittin, joten se on mi-nulle erityisen lheinen.
CH: Onko Post Hotel -hotellilla mielestnnesuuri julkinen rooli kaupunkisuunnittelunnkkulmasta katsottuna?
MM: otta kai. Ruotsin hallitus rakensi posti-rakennuksen itse asiassa kahden korttelin ko-koiseksi, vaikka niiden vlist olisi kuulunutkulkea tie. m esti kaupungin luonnollisenlaajentumisen itn. Raitiovaunujen ja muunliikenteen oli mahduttava rakennuksen vie-ress kulkevalle kapealle kadulle. Uusi kupa-rista ja liuskekivest rakennettu torni osoittaakaupungin uutta itosaa vanhasta keskustastakatsottuna. Lisksi se toimii keskipisteen,
joka sulkee itn pin kulkevan kadun ja par-haillaan hotellin eteen rakennettavan aukion.
CH: Liittyyk kuparilla ja liuskekivell ver-
hoiltuun torniin symboliikkaa?MM: Ei niinkn. Alkuperisess suunni-telmassa torni oli korkeampi, mutta paikal-listen viranomaisten takia sit jouduttiinmadaltamaan. st sa in idean korostaa mit-tasuhteita kyttmll kahta eri materiaalia.Ksittelimme niit mys eri tavalla. Liuskeki-vill peitetyn osan ikkunat ovat pienemmt janiit on vhemmn kuin kupariosassa, miklis rakennuksen massiivisuutta. Kupari-osassa materiaalin tuntu on ohuempi. Monetpienet erot innostavat tulkintoihin.
CH: Oliko kuparin ja liuskekiven kytlle
muitakin syit kuin viittaukset alkuperisenrakennuksen kattoon?
MM: 1920-luvulla paikallisuus nkyi ka ikes-sa. Se oli hyvin luonnollista, ja ihmiset olivatylpeit kuparin kaltaisista materiaaleista. Ha-lusimme kehitt tt perint korostamallauusia osia materiaalilla, joka mahdollisti jat-kuvuuden silymisen. Nen uuden raken-nuksen vanhan rakennuksen nuorena suku-laisena, jolla on sama geeniperim. Kuparillaoli trke rooli suunnitelmassamme.
CH: Kytitte kuparia mys eri levyisin ka
taleina ja patinointisvyin. Minklaistarkoituksia thn liittyi?
MM: Kyll, olen hyvin tyytyvinen tuloseen. apa sopi mainiosti kuparipintojtystmiseen. Itse asiassa kuparilevyjen mutoilussa seurattiin leikattujen liuskekivien kkoja, mik toi pintoihin samanlaista rakenetta. Levyjen horisontaalisuus tuo mieleperinteiset tiilirakennukset, joita on nhtvl kaikkia lla kaupungissa.
CH: Sen lisksi, ett johdatte arkkitehtitmistonne nelj menestyv haaraa, toimimys opettajana. Miten rentoudutte, kun s
hen on mahdollisuus?
MM: Elmni on tasapainottelua, eik vpaa-aikaa ole paljon. Piirrn kuitenkin ainkun se on mahdollista.
Hotellin itpuolelle on suunnitteilla uusi aukio. Torni on hotellille kulkevan kadun kiintopiste.

Euromotors pyysi meit luomaan autojen huoltokes-kukselle uuden yrityskuvan, joka kuvastaisi yrityksentuotemerkin trkeimpi ominaisuuksia: yhtenisyytt,
luotettavuutta ja korkealaatuista palvelua. Rakennus sijaitseevilkkaan tien varrella, mik inspiroi arkkitehtonista konsep-tiamme. Ohikulkevien autojen dynamiikka niiden liike, valot
ja kiiltvt metallipinnat nkyvt heijastuksina rakennuksenjulkisivussa. Aivan jalankulkutien vieress olevaa julkisivuaoli kehitettv kaksiulotteisena pintana, mutta mukaan tuotiinmys kolmiulotteisia piirteit ja horisontaalista liikett.

ARKKITEHTUURIA
Materiaaliksi valittiin tummanruskea esihapetettu kupari.Tm luotettava jalometalli korostaa Euromotorsin asemaa japalveluperiaatteita korkealaatuisten autojen huollossa. Reiite-tyill kuparilevyill rikastutettiin rakennuksen ty yli, ja niidenavulla ulkopuolella liikkuville ihmisille luodaan illuusio muut-tuvasta pinnasta. Pivsaikaan reiitykset tuovat julkisivuunerityist syvyytt valojen ja varjojen ansiosta. Iltaisin dynaa-minen vaikutus korostuu pinnalle heijastuvien autonvalojenkautta. Lisksi levy jen lpi loistavilla erikoisvaloilla luodaanhorisontaalisia kuvioita, jotka muistuttavat autojen ajovaloja.
1900-luvulla rakennettu ruma neuvostoaikainen rakennus
muuttui reiitetyn kupariverhoilun ansiosta autoteolli-
suutta kunnioittavaksi uudenlaiseksi arkkitehtoniseksi
kohteeksi. Aluksi IND Architects -toimiston Pavel Khegay

-yrityksen Andrey Kulagin kertoo suunnitelman
toteuttamisesta.
Tm oli ensimminen Venjll toteutettu projekti, jossajulkisivussa kytettiin takaapin valaistua reiitet tykuparipaneeliripustusta. Suunnitelman tekninen toteut-taminen, arkkitehtien piirustusten ja 3D-mallinnustentulkitseminen asettivat haasteita etenkin valojen, tukien ja
muiden elementtien piilottamiseen. Luonnonmateriaalien,kuten kuparin, kanssa t yskentely inspiroi ja tuo mukanaanerityist vastuuntuntoa. Asennuksen aikana ongelmiltavltyt tiin, sill jokainen yksityiskohta oli otettu huomioon jakuvattu teknisiss asiakirjoissa.
Metallilevyjen reiitys vaikuttaa levyjen lujuuteen, minkhuomioimme tekemll reiki akkiruutukuvion mukaan
ja kuparin paksuutta stmll. Levyjen reunat jtettiinreiittmtt, jotta ne voitiin kiinnitt ruostumattomastaterksest valmistettuihin tukiin kupariniiteill. Valmis
julkisivu kuvastaa Euromotorsin liiketoimintankemyst jaluo mielikuvia autoista ja korkealaatuisesta insinritaidos-ta. Reiitetty kuvio tuo mieleen kerilyauton jhdyttimen, janiittiliitokset muistuttavat lentokoneen pintaa.
Venjll ja muissa maissa autojen huoltokeskukset ovatusein tylsi teollisuusrakennuksia, mutta Euromotors erot-tuu ainutlaatuisen kuparisen arkkitehtuurinsa ansiosta.
Alkuperisen rakennuksen eloton julkisivu vaih-dettiin eloisaan, vivahteikkaaseen reiitettyy nkuparipintaan.

A Platformfor Arts & Creativity
A thoroughly contemporary intervention is at the heart
of the regeneration of the ancient centre of Guimares,
one of Portugals most important historical cities and a
UNESCO World Heritage Site. Locally based architects
Pitgoras discuss their vision and the key role played
by brass profile facades in its realisation.
The buildings that make up the municipal market and thespace contained by them commonly referred to as thesquare together form the urban character of the city ofGuimares. Before being relocated, the old municipal marketenjoyed a privileged and very central location with excel-lent access, very close to the Toural Square and the historiccentre.
MULTIFUNCTIONAL SPACE
Now, the transformation of the marketplace into a multi-functional space dedicated to artistic, economic, cultural andsocial activities appropriate to the citys European Capital ofCulture 2012 status, has reintegrated the area into the urbanfabric, so recovering a key area of the city. In addition, theproject extended out to adjacent building plots, enabling theregeneration of the interior space of the block previously acharacterless area used for marble processing.
The program provided a clear concept and defined theobjectives to be achieved, listing a series of activ ities andspaces which defined the functions of both new and existingbuildings, as well as the adjacent plots of land. Three majorprogram areas were identified:

The program also sought to recover the existing building onthe eastern side by trying to promote the installation of ad-ditional multidisciplinary commercial activities. The wholestructure, according to the program, would complementexisting facilities in the city, as well as those under develop-ment as part of the European Capital of Culture.
When interpreting the program, we aimed to allow for thepossibility of each one of its components functioning inde-pendently and simultaneously, by creating accesses to eachof the various services and support areas, as well as to theoutdoor square and garden.
We opted for a methodology of intervention that involvedthe rehabilitation of the existing building to the east keeping the materials and textures but redoing the entireinterior at level 0. With the north building, the faadetowards the Avenue which characterises the build-ing was renovated but its interior and faade facing thesquare were the subject of almost complete demolitionand redesign. Although it was intended to maintain thescale and the existing formal relations, we proposed a
new solution for the building that promotes a strong rela-tionship with the square and emphasises the relationshipof this structure with the outer space.

The new building takes a radically different approach to itssurroundings, both from the standpoint of architecturallanguage and image: discrete, repetitive, as well as by thesuccession of volumes, with full and empty, marked by the
juxtaposition of contrasting sur faces. The external coverings
a grid of brass profiles and tinted glazing over ventilated fa-ades accentuate a range of textures changing from denseand opaque on the majority of surfaces, to transparent whenpartially concealing the buildings few openings.
This series of dissonant elements resulted from the need tocreate a variety of different spaces in the exhibition area.It creates a tension manifested in the volumes of the buildingand the relationship with the space of the square, making itthe main feature of its design.
For the square, we formulated a design significantly moreclinical, using large concrete slabs which act as a counterpart
to the surrounding buildings. It is conceived as a large mul-tifunctional meeting area and obviously a public space byits very nature. It will remain intentionally sparsely equipped,with large trees to the east preserved and planting introducedalong the north building, but leaving most of the space freefor spontaneous or organised activities on the Plat form.

A TRANQUIL
BACKDROPIN BRASS
The architects choice of brass for the facadesof the new building was informed by the mate-rials ancient heritage, sustainability credentialsand ability to deliver a cost-effective solution tothe complexities of the program. Brass profiles,in conjunction with exposed glazed areas, ef-fectively dematerialise the massive geometricforms of the new building which is 150 m longand stands 8 m high sof tening its relationshipto the public square.
The consistent grid, made up of 20 x 10 mmrectangular brass profiled sections, matchesthe scale and proportions of the surroundingbuildings without overwhelming them. Despitethe regularity of the brass grid, it provides atranquil backdrop to the square, constantlychanging with the light then transformingfrom opaque to transparent at night.

In the summer of 2006 Maidstone Borough Councillaunched an exciting and ambitious scheme to openup Maidstone Museums collections and transformits services and facilities for visitors. The East Wingproject forms the second phase of the Museums re-development programme, following the renovation of
the West Wing in 2003. The Museums core is a Tudormanor house dating from 1561. It was acquired byMaidstone Borough Council in 1855 and opened asa Museum in 1858. The Museum is a Grade II* listedbuilding protected by law.
More Public InvolvementThe collections of over 600,000 ar tefacts and speci-mens are outstanding in their diversity and quality,forming the largest mixed collections in Kent and oneof the largest in the South-East of England. Someelements such as the Japanese Art Collection are ofinternational significance. The East Wing projectskey aims were the long-term preservation of the col-lections, more public involvement and increased useof the Museum and its collections.
The new interventions allow greater public visibilityof the collections and also the Museums historicbuildings. There is now a visual reconnection toBrenchley Gardens, as originally intended by theMuseums Victorian founders, and better views of theMuseum from the town centre. Public facilities, easeof visitor flow through the building and accessibilityfor all have also been substantially improved.
Hugh Broughton Architects explain the project for
the upgrade of Maidstone Museum, a protected
historic building in the South-East of England,
dating back as far as the time of King Henry VIII.Their thoroughly contemporary design involves
crisply detailed golden copper alloy and glass
rectilinear forms, interweaving amongst ancient
buildings to create new vistas from both inside
and out.

Winning DesignOur competition-winning design is a direct response tothese key objectives. At the lower levels of the revitalisedEast Wing, a new entrance and orientation area faceMaidstones High Street and welcome visitors. A gallerycreated between an improved shop and the refurbishedstores provides a home for a Solomon Islands War Canoe the only example of its kind outside the Islands. V iewsfrom this gallery reveal a public courtyard and Tudorfaades unseen by the public for over 40 years.
A young learners education room is complementedat first floor level by a glazed meeting room, creatingdramatic views of St. Faiths Church and visually re-con-necting the museum with Brenchley Gardens. A dynamicnew gallery space above the reception, lit by curvaceous,north facing rooflights, provides a permanent homefor the collection of Japanese Art. The extensions werecomplemented by refurbishment and reorganisation ofthe existing galleries at the east end of the Museum,
increasing display space by 30 %.
New elevations combine frameless glazing with a diagridof golden copper alloy shingles, creating a contemporarycounterpoise to the existing brick faades. Over time theshingles may loose their shine but not their beauty.

CONTEXT
CH: How did you come to design the new
university building and what are the contex-tual impacts of its surroundings?
EK: Te Linguistic department buildingresulted from a competition in 2006, which
our office won. Te new building is locatedin Powisle Plnocne Warsaws Latin Quar-
ter and home to the University of Warsaw
and the Academy of Fine Arts. Te area sits
at a lower level than the main University and
Academy buildings and the Old own: this
picturesque topography played an important
part in our design strategy. Immediately
adjacent is the copper-clad University Library(opened in 1999) which also influenced the
new building particularly its materiality.
CH: What was the strategy behind your
design and the different faade treatments in
particular?
EK: Our project was considered as a sort of
a promenade, linking the higher University
campus to the Library. Along this promenadewe situated all reading rooms demanded by
the programme of different faculties belong-ing to the Linguistic Department. In order
to connect the two new buildings we used a
glass wall along Dobra Street which reflects
the rich copper facade of the Library with its
engravings and texts in different languages.Te 140 m long southern wall along Lipowa
Street aims to give readers the impression of
being in a garden space where light flickersthrough green leaves, creating a special, col-oured light inside a sunny environment,
despite gloomy weather outside.
Tis is achieved using yellow, green and lime
foils on the double- skin glazed southern
facade.
CH: What are the reasons for the variety of
treatments and materials on the facades?
EK: Te whole project is in two phases andthe now-completed first phase represents only
a third of the whole complex. So the impres-
sion given by some facades is temporary.
When complete, the whole building wil l read
as having two wall finishes essentially, glass
and copper.
CH: Why did you choose pre-patinated copper?
EK:. We selected copper for a number of

reasons. Firstly, to accentuate the character of
the district which is full of parks and close to
the river. But, of course, the green mood of
new architecture was previously introducedby the Library building. Although continu-ing down this line of thought, we choose a
different finish for the copper pre-patinated
with a living surface colour to differentiate
our building from the Library. But we also
wanted to show the variety of copper finishes
which are possible.
Copper is a living material, like nature. Its
appearance changes over the years, with theweather, at different times of the day and in
different lighting conditions. Tis is demon-
strated on the Wislana Street faade which ismostly copper, including service door facings.
Also on this facade, the idea of introducing
yellow patches amongst the copper was to
enliven it with artificial sun-beams. Tere
is also a timber patch on this elevation,
signalling a wooden terrace on the roof whichslides down the elevation. Te full effect
will become clear when the whole complex is
finished.

SEAMLESS ARTICULATION
The Hive, Worcesters recently opened Library and HistoryCentre certainly has a striking presence. A beacon for learn-ing, it is a key part of Worcesters river frontage, highly visiblefrom the rising ground to the south and west. The articulationof its unique external form resonates with the scale and grainof the setting: the roofline echoes the profile of the MalvernHills visible to the west, and recalls the Royal Worcester kilnswhich, with the Cathedral, once dominated the citys skyline.The iconic funnels are as fundamental to the interior of thebuilding as they are to its external appearance, providingnatural light and ventilation to the heart of the floor plates.
The Hive evolved from a groundbreaking partnership to create
a fully integrated public and university library, which is com-pletely new to the UK and highly innovative internationally.The building also includes the county archives and recordoffice, a local history centre, the countys archaeology serviceand a multi-agency customer service centre. The Hive is acultural, learning and information centre of excellence promoting lifelong learning, engendering social inclusionand raising aspirations in the broadest sense for the wholecommunity, regardless of age, background, or ability.

The cladding of golden copper alloy shingles reflects the richpalette of colours and materials which characterise the citycentre - the red and gold of brick, terracotta and stone embel-lished with gilded filigree and finely decorated encaustic tiles.The elevational language of solid walls and punched openingsalso draws on the local vernacular: solid and void are balancedto optimise light, air and view, with care to avoid overheatingand glare, and the need for excessive mechanical systems tomaintain a comfortable environment.
The articulation of the roof form as a ser ies of irregular conesis designed to reduce the scale of this significant new publicbuilding to better relate to the fine grain of the historic city.
The distinctive roof cones are formed in solid laminated timberpanels that span between the eaves beam and a timber ringbeam at the top of each cone. The plinth, which varies in heightaround the perimeter, is clad in Forest of Dean Pennant stoneto match the paving to the public realm: the ochre streaks echothe golden cladding.
by Nick Hodges, Envelope Package Architect for Feilden Clegg Bradley Studios
Golden CloakThe copper alloy cladding was chosen to allow the use ofa single material to roof and elevations a golden cloakdraped over the form. The scale of the 600 x 600 mm tilesand the slight offset with which they are laid gives the im-pression of carapace of scales. As an architectural language,the copper shingles are articulated as thin expressedat the window reveals and soffits as 25 mm deep, with theremaining depth to the glazing finished with dark anodisedaluminium to match the curtain walling.
The shingles are intentionally overlapped rather than tightly
coursed to provide a natural element of variation thatallowed openings in the copper alloy to be more freely po-sitioned. It was felt that had the coursing been tighter thenthe resulting small cuts at openings would have been morenoticeable. It was calculated that the dif ference in additionalmaterial was around 1 % and this was considered acceptablein terms of ease of working on site. More critically it was feltthat the coursing of the copper should align from the walls tothe roof cones, so that there was a feeling of continuity.

Articulation of the metal fabric was developed in the
detailing of the material at corners, eaves and windowcills. A critical part of the material expression was toensure that it appeared seamless and that cover piecesor horizontal elements of gold that might break up theshingle pattern were avoided. The design team wereaided by the excellent copper installers who mocked-up a number of the key detail junctions (some shownhere) for discussion and exploration ahead of the startof their site works.
As the installations progressed to site, the installersidentified potential difficulties with particular gutter
junctions early enough for the design team to discusspractical solutions on site. These conversations weresupported by sketches and formal drawings, and test-ing where necessary. The quality of the copper alloyskin, as part of the overall finished building, is evidenceof how well the design and installation team workedtogether.
At nearly 12,000 m2 it would be easy for the sheervolume of such a striking material to be the definingcharacteristic but, by developing the details togetherwith a dedicated and skilled installer, the claddingbecomes more than simply distinctive. Instead, the
prominence of the material is embellished and refined:the subtleties of the golden cloak demonstrated in itscareful stitching together.

SOLAR WAVESOne of Londons best-known public sector schools has been completely redeveloped with
a single, state of the art building replacing a sprawling campus. The competition-winning
design takes an innovative, highly architectural approach to controlling and optimising
sunlight with its brise soleil arrangement of copper, brass and bronze fins.
Opened in 1958, Holland Park School became the flagship forcomprehensive education in England, known as the social-ist Eton due to its impressive reputation. But by 2004, whenan architectural competition for redevelopment was insti-gated, the schools existing buildings were beyond economicrepair and failed to meet modern demands, with inflexibleaccommodation and tortuous circulation. The greatest chal-lenge for architects Aedas was to design a new building to bebuilt on the original site while the existing school remained inoperation and that allowed part of the site to be sold to fundthe construction but also left more usable external spacethan before.
Two Halves United
The result is a new block, approximately 100 m long and30 m wide. A large, 7 m deep basement extends across theentire building footprint to a depth of 7 m, accommodating thesports hall and swimming pool as well as kitchen and dining
areas. The above-ground, five storey parts are conceivedas two distinct halves united by a central atrium stretchingits full length and linked by a series of walkways. The easthalf contains the more conventional teaching spaces andis constructed using in-situ concrete columns and flat slabconstruction. The west half is a more dramatic, steel A-framestructure enabling the larger teaching and assembly rooms.This structure then straddles the larger spaces within thebasement to create clear-span spaces.
Maximising natural lighting deep into the building with exten-sive glazing, while controlling glare and solar gain, provedcentral to the architects strategy for design of the facades.But reducing visual impact of the long block on its sensitivesurroundings close to Holland Park and with mature treeson site was also impor tant. The east elevation is finishedwith a gently undulating stainless steel mesh, passing overa central copper canopy signalling the main entrance.

Dynamic Three-dimensional Character
In contrast, the west facade is defined by a series of verticalfins in pre-oxidised copper, brass and bronze which take on astrong, dynamic three-dimensional character. The architectfor the project, Peter Runacres, explains the development oftheir design: Due to the buildings orientation, this eleva-tion receives more solar gain than the east side and vertical
fins are more effective in controlling glare while maximising
daylight. The initial design had an arrangement of broken up,
smaller fins but solar gain computer modelling revealed that
more were needed.
We then experimented using a physical model and found that
this arrangement created too much visual mass so, instead,

The copper and copper alloy clad fins are thin in section,minimising the impact on views from inside the building. Buttheir depth acts as an effective barrier to glare and unwantedsolar gain from afternoon sunshine. Viewed from an angle,the fins come together to generate a stunning effect of dy-namic sinuous forms across the faade.

Improving the environmentalperformance of products forconsumers and the buildingconstruction sector is importantto the copper industry. EU initi-atives, such as the SustainableConsumption and Productionaction plan, emphasise greaterresource efficiency and thecommercialisation of environ-
mentally friendly products. Thecopper industry is at the fore-front of industries committedto reducing the environmentalimpact of its operations. Today,one third of the energy consump-tion of modern European coppermanufacturing is used to operate envi-ronmental protection measures.
Recently, the copper industry has de-veloped an environmental profile whichcovers around 90% of the EUs produc-tion of both copper metal and copper
products. A critical review by externalexperts has confirmed the high qual-ity, consistency and correctness of theresults. Based on ISO 14040/44, all as-pects of ore extraction, the productionof other raw materials, energy supplyand the production of the metal itselfare detailed. As such, it captures the fullimpact of the so-called cradle-to-gateapproach and shows where the greatestenvironmental impacts occur and whereimprovement actions would deliver themost benefits.
Whilst this profile is based on a cra-dle to-gate assessment, many of thebenefits to society derived from copperwill be found during the downstreamuse phase. The copper industry pro-vides support to those wishing to usethe LCI data in their own Life Cycle As-sessments including the use phase andend-of-life phases.
Only about 20% of the total impact aris-es from EU copper production sites,influenced mainly by technology, lo-cal authority permit requirements, thesource of energy supplying the produc-tion site and a companys own standards.Geologically, copper is associated with
other valuable metals, such as molybde-num, silver and gold. Since their naturalconcentrations are much lower, the oreneeds careful treatment. Modern miningtechniques require less energy than inthe past, making the recovery of smallamounts of metal possible.
Copper Construction Products inGreen Building Rating SchemesIn the last few years, sustainable archi-tecture has evolved from an add-on to anexpectation and societys understand-
ing of what a sustainable building is hasbecome more complex. Sustainablebuilding rating systems have respondedto this shift by expanding their focusfrom operational impacts towards amore holistic life cycle approach.
To date, various green building ratingschemes exist. They differ in their ap-proach to considering building product
sustainability in the context ofthe whole building. LCAs areprovided by the copper industryto represent the ecological per-formance of copper products(e.g. sheets, tubes and wire ofcopper) in a transparent way.Moreover, the copper industryhas developed EnvironmentalProduct Declarations (EPD)
based on LCAs for commu-nicating reliable quantitativeenvironmental data for prod-ucts based upon independentlyverified calculations.
Life Cycle Assessment (LCA) inBuilding Rating SchemesThe BRE Green Guide to Specification isa useful starting point for assessing thesustainability of architectural materialsand provides independent endorsementof the low environmental impact of both
copper roofing and cladding. It rates awide range of complete building elementsfrom A+ to E, using LCA techniques.Ratings form an important part of theCode for Sustainable Homes and otherassessment tools such as BREEAM.
Various complete wall or roof build-upsare considered, each including materialsfor structure, insulation, moisture con-trol and finishes. All the copper-finishedroofs and most copper wall claddingspecifications included achieved A+ orA summary ratings. Even the few build-
ups with lower ratings could be improvedeasily with replacement components,without affecting the copper skin itself.Coppers longevity is a major strength,resulting from its complex patinationprocess that ensures extreme durabil-ity with no maintenance and resistanceto corrosion in virtually any atmosphericconditions.

But despite these high summary ratings,coppers life-span is one aspect that theGreen Guide simply underestimates. Itincludes unexpectedly low replacementintervals for copper cladding and roof-ing generally just 45 years that arenot justified either by experience or byscience. Many historic copper roofs have
survived for hundreds of years and some
are known to have performed well forover 700 years.
Below are some examples of gainingcredits in green building rating schemes,but there are many more opportunitiesto use copper to gain credits in buildingrating schemes not least in plumbing, re-
newables, heating and cooling.
The UKs Environmental AssessmentMethod for Buildings (BREEAM 2011)Credits are available for using specifi-cations for key building elements (e.g.external walls and roofs) with low embod-ied environmental impact as measuredby the Green Guide to Specification.Copper product manufacturers provingthat their product is better than the aver-age in terms of embodied impact of the60 year study period, because of reduced
impact in manufacture, reduced mate-rial or increased durability can obtainproduct specific Green Guide ratings byundertaking certification to BRE GlobalsEnvironmental Profiles Scheme.
For the responsible sourcing of ma-terials, credits can be achieved whenconstruction materials at least 80 % ofmaterials used - are responsibly sourced.Points are awarded depending on the type
of certification available for the materialsused in each building element.
The USs Leadership in Energy andEnvironmental Design (LEED)This system developed by the US GreenBuilding Council addresses: Sustain-able Sites; Water Efficiency; Energy &
Atmosphere; Material & Resources; In-door Environmental Quality andInnovation & Design. Life-cycleis not part of the current version(LEED 2009) but it will be incor-porated into the next one (LEEDV4) that will assess the buildingslife cycle impact reduction. LEEDcategories where copper cancontribute include:
MR Credit 1 Building reuse:credits can be achieved if build-
ing products can be reusedduring renovations, which is usu-ally possible due to the durabilityof copper.
MR Credit 2 Diversion fromlandfill: credits apply to end of
life of the building and its materials. Sinceit encourages the recycling of productsinstead of their disposal, credits can beachieved if materials such as copper areused in buildings which have a high valueas secondary materials and high recy-cling rates.
MR Credit 4 Recycling content: creditsare given if the recycled content of usedmaterials in the construction is high. Usu-ally, this is the case for copper products.
MR Credit 5 Regional materials: i.e.extracted, processed and manufacturedregionally. If copper products from re-gional processing or manufacturing sitesare used in buildings, additional creditscan be achieved.
SS Credit 7 Heat island effect: creditsare awarded depending on the Solar Re-
flection Index (SRI) of the roof, walls andsite paving area. If copper is used as a roofor cladding, manufacturers can providean initial SRI and one 3 years after instal-lation.
The German Sustainable BuildingCouncil (DGNB)This rating scheme addresses the threepillars of sustainability. It doesnt as-sess individual measures, but the overall
performance of buildings and an LCA caculation are mandatory.
ECO1.1 Life cycle costs (LCC): the manufacturing costs of faade and roof havto be considered. No maintenance costduring use phase. Please note, the end olife scenario is not part of the LCC calculation.
SOC1.6 Exterior quality: this criterioevaluates the design of outdoor areas.The goal of the criterion is to maximizthe roof area by integration of technicastructures in the building and reductioof fascia/parapets. Special outdoor area
(balcony, loggia, terraces, etc.) gain morpoints in this criterion.
TEC1.6 Ease of dismantling and recyclingcopper is a non-toxic, recyclable material, which is a requirement for a gooevaluation of this criterion. The effort odismantling and sorting is low and thvalue is high, which helps ensure the reuse of copper metal at the end of its life.

The Prfecture du Rhne building designedby architects GARBIT & BLONDEAU is theadministrative centre for the Rhne depart-ment, demanding a strong public presence. Itreplaces a previous building on a corner plotin the central Third Arrondissement of Lyon,the departments capital city. Its plan-form isstraightforward with six storeys plus a set-back penthouse and external roof areas, anda 2-storey basement.

with the suspended stainless steel meshscreens at street level, the perforated cop-per gives transparency but the motorised,pivoting shutter arrangement also animatesthe facades. This brise soleil arrangementallows direct response to external condi-tions, controlling solar gain and glare, whilstmaximizing potential for daylighting deepinto the building. This strategy is thoroughlysustainable in terms of both environmentalperformance and choice of materials.

Environmental Control with CopperThe external copper shutters each pivot centrally and areoperated in groups by electric motors, enabling local re-sponse to external conditions in combination with openingwindows for ventilation. Even when closed, the shutters allowfiltered natural light into the building and, at night, internal
lighting transforms the building when seen from outside.The purely architectural impact of the design can be judgedby comparison with the new facades before the brise soleilwere installed.
