FRNDRING OCH KONTINUITET

Vi brjar det hr numret med att rikta ett varmt tack till Lennart Engstrm som nu gr

i pension frn redaktionsteamet. Han tog initiativet till Copper Forum fr 18 r sedan

och har sedan dess haft en nyckelroll i tidskriftens utveckling, frn den frsta utgvan p

fyra sidor avsedd fr skandinaviska ark itekter till dagens 40-sidiga paneuropeiska utgva

som publiceras p 13 sprk. Alla vi i redaktionsteamet har vrdesatt hans klokhet, hans

passion fr koppar inom arkitekturen och hans vnliga men nd bestmda personlighet.Det var alltid roligt att arbeta tillsammans med Lennart.

Sjlvklart har det skett frndringar under de 33 nummer av tidskriften som publi-

cerats hittills. Vi frsker hela tiden frbttra tidskriftens design och innehll, s att det

terspeglar arkitekternas intressen. Det rder dock inget tvivel om att Copper Architec-

ture Forums krnvrden r desamma: att presentera inspirerande, samtida arkitektur och

andra mnesomrden som har med designrelaterad koppar och dess legeringar att gra.

Vi vill ocks ta tillfllet i akt och presentera vr nye chefredaktr, Robert Pinter,

och den nye redaktren, arkitekt Chris Hodson. Bda r sedan tidigare medlemmar i

redaktionsteamet och har gedigen kunskap och erfarenhet av koppar inom arkitektur och

konstruktion. Med en arkitekt som redaktr kommer tidskriften att i nnu hgre grad

terspegla intressena hos de arkitekter som lser tidskriften och utveckla relationen med

dem srskilt via vr partnerwebbplats copperconcept.org.

I Copper Architecture Forum frsker vi belysa vxande trender och gemensammaberringspunkter mellan olika projekt. I detta nummer kommer ni att lgga mrke till ett

antal teman. Frst och frmst ger vi exempel p byggnader dr man anvnt fasadelement i

koppar fr att kombinera solskydd och ljusgenomslpplighet. Lsningarna som exempli-

fieras r allt frn skrmar och nt i perforerad koppar till ntverk av profilerad mssig och

skulpterade, vgformade konstruktioner. I vissa projekt lyfts koppar ven fram som ett

genuint modernt material som ger karaktr t moderna nybyggnationer i renoveringen av

ldre byggnader ofta historiska och med skyddsstatus. Slutligen har kopparn en annan

viktig funktion i att bidra till formgivningen av stadsmiljn i stort.

Vi hoppas att du i det hr numret ska f mnga tillfllen att njuta av mngfa lden

och perfektionen i arkitektonisk design.

STILBILDANDEKOPPAREfter att ha sttt outnyttjat i 20 r, har det gamla

posthuset p Drottningtorget i centrala Gteborg nu

omvandlats till Clarion Hotel Post ett hotell med500 rum och med moderna nybyggnationer som

terspeglar andan i denna pulserande stad.

Originalbyggnaden utformades mellan 1918 och 1925 av denGteborgsbaserade arkitekten Ernst Torulf i en klassisktmanieristisk stil i tegel, stenutsmyckningar och brutna skif-fertak med koppardetaljer som med tiden ftt en grn patina.Postkontoret r numera listat som nationellt monument. Ar-kitekterna Semrn & Mnssons bedrgligt enkla strategi varatt utplna tomrummet i den ursprungliga, hstskoformadelsningen med hjlp av en nybyggnation som skulle vndaint mot det gamla postkontorets lastgrd. Den befintligabyggnaden renoverades och anpassades till sitt nya anvnd-ningsomrde, samtidigt man bevarade ursprungsbyggnadenskaraktr, detaljer och skyddsstatus. terstoden av innergr-den fylldes ocks med nya, lgre konstruktioner. Exempelvisser ett glastak till att ljus fldar in i allmnna utrymmen.

Ett nytt landmrke fr staden

Konstruktionen som avgrnsar grden ger byggnadens strasida en ny fasad mot kareplatsen och Odinsgatan. Nybygg-

nationen gr frn sida till sida med en kopparkldd flygel ochen skifferkldd samma material som i det gamla posthuset jmns med den ursprungliga takfotsnivn. Nr flyglarnamts reser de sig upp tillsammans som ett par monolitiskakolosser, tskilda av en lodrt glasskiva. Resultatet ett 13vningar hgt torn utgr stadens nya landmrke och inne-hller ocks en extraingng till hotellet: huvudingngen, sommed sin verddiga guldmosaik inte gr att missa, ligger pden befintliga byggnadens vstra sida, mot Drottningtorget.

av Chris Hodson

Tillbyggnaderna respekterar och terspeglar det horisontellarutntet i den gamla fnsterlayouten men upplser de enkla,vertikala raka linjerna. De nya fasaderna uppfattas som fyr-kantiga paneler, var och en med vgrta band av koppar ellerskiffer och slta till synes slumpmssigt utplacerade in-fllda glaspartier. Enligt arkitekterna har man i ut formningenav ytan hmtat inspiration frn Lajasalo-kyrkan i Finland ochdess horisontellt placerade frpatinerade kopparband.

Men hr terupprttas vertikaliteten av panelfogarna, sombetonas av frgfrndringarna i mtet med de horisontellakoppar panelerna. Hrnen illustreras med en modern variantav de traditionella, vertikala hrnstenarna (som terfinnsp den ursprungliga byggnaden) som en tunn strimma panelernas tjockaste del ibland med inglasade partier motkopparen. Rutntet i fasaden r oavbrutet trots en solterrassp taket och en ppen pool med utsikt ver Gteborg.

Fylliga, levande kopparytor

Frn brjan frestllde sig arkitekterna de nya

fasaderna som en tunn, pltbekldd konstruktionLsningen inkluderade diskreta, fabrikstillverkadpaneler som sedan monterades i sin helhet pplats, s att de bildade en curtain wall-fasad,fristende frn byggnadens vningar. Dettagjorde att man kunde kontrollera komplexiteten iutformningen av de enskilda panelerna i sjlva fa-sadlayouten, med glaspartier i olika storlekar ochen varierad, patinerad kopparyta. Denna tillverkade man av koppar i tre olika plthjder 200, 250och 300 mm och tre olika intensiteter av frpati-nerad koppar, genom att variera mngden av den

grna patinan ovanp den mrkbruna oxideradebakgrunden. Genom att kombinera dessa elemenlyckades man skapa fylliga, levande koppary tor

Viktig roll i samhllet

Clarion Hotel Post ligger mitt i centrala Gteborg, bredvidcentralstationen och det stora kpcentret Nordstaden. Detnya tornet har en viktig roll i samhllet som symbol ochsamlingspunkt och vver dessutom samman delar av sta-den som lnge har varit tskilda. Det mest uppenbara r atttornet har anpassats till Odinsgatan och sprrar av utsikten

lngs denna raka aveny. Dessutom reser det sig ver detgamla posthuset nr det beskdas frn torget och andravikiga platser i stadskrnan.

Obetydlig miljpverkan

Under planeringsstadiet frde man diskussioner medGteborgs stads miljfrvaltning om vilka miljeffekterregnvattenavrinningen frn kopparen skulle f fr Gta lv.Professor Inger Odnevall Wallinder frn Kungliga Tekniskahgskolan genomfrde d en miljkonsekvensstudie somkom fram till att den ytterst ringa mngd koppar (160230 g)

som varje r skulle kunna hamna i lven endast skulle geobetydliga miljeffekter. Enligt studien skulle de sm koppar-mngderna med strsta sannolikhet fastna i andra material inrheten av byggnaden. Denna koppar skulle inte ens mrkasi de uppemot 20 ton bakgrundsmaterial som redan trans-porteras av floden varje r. Kopparmngden skulle ge sammaeffekt som om 300 personer som bor i nrheten av hotelletvarje dag t vitaminpiller med 2 mg koppar i.

Hela intervjun med Magnus Mnsson

hittar du p www.copperconcept.org

INTERVJUChris Hodson diskuterar Clarion Post Ho-tel med professor Magnus Mnsson, gareav arkitektfirman Semrn & Mnsson.

CH: Hur gick det till nr du blev involverad

i Hotel Post-projektet?

MM: En byggherre bad mig hitta en plats fr

ett stort hotell hr i Gteborg, nra centralsta-

tionen. Jag arbetade just d med ett annat ho-

tell och var vl frtrogen med strukturen i den

typen av byggnader. Posthuset hade i slutet av

1980-talet omvandlats till kontorsbyggnad,men nr jag tittade p huset tnkte jag: Det

hr r inte en kontorsbyggnad, det r ett hotell

bara p grund av fnstrens placering. Bygg-

herren gick med p mitt frslag och vi startade

ett spektakulrt projekt dr nytt och gammalt

frenades. Det var tta r sedan.

CH: Vilka var de strsta utmaningarna medatt arbeta med en sdan spektakulr, riv-ningsskyddad byggnad?

MM: Frst och frmst hade vi frsts en kamp

med olika myndigheter. Byggnaden r skyd-

dad enligt hgsta skyddsstatus i Sverige, och vi

diskuterade inte bara med de lokala myndig-

heterna utan ocks med den nationella organi-

sationen i Stockholm, s det var verkligen en

kamp. En av utgngspunkterna var att vi inte

fick ndra ngonting p utsidan.

CH: ven om ni har tre andra kontor r nilokalt baserade i Gteborg. Agerar du olikaberoende p om ett projekt ligger nra ellerlngt bort rent geografiskt?

MM: Det hoppas jag inte. Men den hr bygg-

naden ligger frsts srskilt nra mig eftersom

jag passerar den varje dag nr jag ker hemi-

frn.

CH: Anser du att Post Hotel spelar en viktigroll i samhllet, ur stadsplaneringssynpunkt?

MM: Ja, det gr det verkligen. Nr den svenska

regeringen byggde posthuset upptog det fak-

tiskt tv kvarter, ven om det var meningen att

en gata skulle g igenom. Projektet satte stoppfr stadens naturliga expansion sterut, med

endast en smal, sprvagnstrafikerad gata som

lpte ttt intill byggnaden. S det nya koppar-

och skiffertornet markerar den nya stadsdelent ster, sett frn den gamla stadskrnan. Men

det fungerar ocks som central punkt som

stnger av avenyn t ster, och man hller fr

fullt p och planerar ett nytt torg framfr det.

CH: Finns det ngon symbolik i de tv kop-par- och skiffertornen?

MM: Nej, egentligen inte. I originalritningen

var tornet hgre, men det satte de lokala myn-digheterna stopp fr. Det var d jag kom pidn om att gra tornet i tv olika material

fr att uppn bttre proportioner. Och det

finns skillnader i hur vi arbetat med de tv

materialen. Fnstren i skiffertornet r min-

dre och frre, vilket skapar en monolitisk

knsla. Knslan nr det gller koppartornet

r att materialet r mycket tunnare. Det finns

mngder av sm tecken som uppmanar dig

att tolka ski llnaderna.

CH: Fanns det andra orsaker till att du valde

koppar och skiffer n att skapa en referens tilltaket p originalbyggnaden?

MM: P 1920-talet var allt vldigt lokalt,

men ocks mycket naturligt, och man var

stolt ver att ha material som till exempel

koppar. Vi ville vidareutveckla detta arv med

ett materialsprk som gav de nya delarna sr-

prgel, men nd kontinuitet. Jag ser den nya

byggnaden som en ung slkting med sammaDNA som den gamla byggnaden. Kopparn

var mycket viktig fr formgivningen.

CH: Och du har anvnt koppar med oli

styckbredder och patineringsstyrkor. Vilvar dina avsikter med detta?

MM: Jag r mycket njd med resultat

Det var ett fantastiskt stt att utforma ko

parytorna p. Storlekarna p de skurna sk

ferplattorna gav upphov till idn att vi sku

arrangera kopparplattorna p samma stt fatt skapa samma textur, och horisontalitet

terspeglar det traditionella murverket so

fanns i hela staden.

CH: Frutom att du driver en framgngsrarkitektbyr med fyra kontor, undervisar

ocks. Hur kopplar du av?MM: Det r ett stndigt pusslande, och jag

nstan aldrig ledig. Men om jag fr tid vtecknar jag grna.

Ett nytt torg r planerat ster om hotellet, dr tornet fungerar som blickpunkt fr avenyn bakom.

Euromotors bad oss skapa en ny image till fretagetsservicecenter. Den skulle terspegla grunddragen ifretagets varumrkesfilosofi: stadga, tillfrlitlighet

och hgkvalitativ service. Byggnaden ligger p en trafikeradgata, ngot som inspirerade vrt arkitekturkoncept. Dynami-ken hos frbipasserande bilar deras rrelser, belysning ochblanka metallkarosser alla dessa bilder projekteras i bygg-nadens fasad. Byggnaden ligger ttt intill en allmn gngvg,och fasaden mste ha en tvdimensionell yta som samtidigtantyder en tredje dimension och en horisontell rrelse.

FORDONS-ARKITEKTUR

Mrkbrun, froxiderad koppar valdes som material. Dennafrfinade och plitliga metall understrk Euromotors statusoch serviceknsla nr det gller hgkvalitativa bilar. Perfo-rerade kopparpaneler frhjde byggnadens utseende och gaven illusion av att y tan frndras nr man promenerar utanfr.Dagtid ger perforeringarna ett srskilt djup t fasaden tackvare ljus- och skuggspelet utanfr. P natten frstrks dendynamiska effekten av att bilarnas ljuskglor terspeglas pytan och ocks av srskilda lampor som lyser igenom pane-lerna i horisontella mnster som bilstrlkastare.

Omvandlingen av en anskrmlig sovjetisk byggnad med

perforerad kopparfasad, uppfrd i mitten av 1900-talet,

leder till terupptckandet av en arkitektonisk typologi

som hyllar bilen. Frst frklarar Pavel Khegay och Amir

Idiatulin frn IND Architects sitt designkoncept.

Hr diskuterar Andrey Kulagin frn den tekniska

konstruktions- och installationsfirman PacificStroy

genomfrandet av designen.

Detta var det frsta projektet i Ryssland dr en hngandefasad av perforerade kopparpaneler med bakgrundsbe-lysning anvndes. Det innebar ett antal utmaningar fross i frga om teknisk design och att tolka arkitekternasritningar och tredimensionella visualiseringar i synnerhetindirekt belysning, stdanordningar och andra objekt i detmellanliggande tomrummet i fasaden. Man knner alltid ettsrskilt ansvar och en srskild inspiration nr man arbetarmed naturmaterial som till exempel koppar. Och ef tersomvarje liten detalj beaktades och beskrevs i den tekniskadokumentationen lyckades vi undvika problem under instal-lationsprocessen.

Att perforera metallpaneler pverkar stabiliteten, ochdetta ordnade vi genom att gra hl i schackbrdemns-ter och justera kopparens tjocklek. Hrnen p panelernalmnades operforerade fr att man skulle kunna fsta demmed kopparbultar p stdanordningarna av rostfritt stl.Den frdiga fasaden terspeglar Euromotors affrsstrate-

gier och skapar associationer till bilar och till hgkvalitativtingenjrsarbete. Perforeringsmnstret r som radiatornp en gammaldags bil, och de nitade fogarna pminnerom ytan p ett flygplan.

I Ryssland och mnga andra lnder r fordonsservice-center ofta ansprkslsa industribyggnader, men Euromo-tors str verkligen ut med sin unika arkitektur i koppar.

har inspirerats av formen p de lokala byggnaderna och

sedan konstruerats i en modern tappning med stora ytor

av skiffer, glas och koppar.

Projektet bestr av tv olika flyglar som frenas i ett centraltbelget receptionsomrde. I den 65 meter lnga stra flygelnligger multimediebibliotek fr barn och vuxna. Den vstra flygelnr ngot lngre, nrmare bestmt 75 m, och hr finns en musik-

skola och en dansskola. Arkitekterna efterstrvade en modern,centralt placerad byggnad som omvrderar relationen med denaturliga omgivningarna (trdgrdar, aller, stenmurar) ochbyggnationerna (svl traditionella som tillflliga byggnader).De frestllde sig de kulturella utrymmena som frgreningartill sjlva stammen receptionsomrdet.

A Platformfor Arts & CreativityA 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.

7/30/2019 Caf34 Se Web

16/40


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 TRANQUILBACKDROPIN BRASSThe 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 forthe upgrade of Maidstone Museum, a protectedhistoric building in the South-East of England,

dating back as far as the time of King Henry VIII.Their thoroughly contemporary design involvescrisply detailed golden copper alloy and glassrectilinear forms, interweaving amongst ancientbuildings to create new vistas from both insideand out.

CONTEXT

CH: How did you come to design the newuniversity 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 yourdesign 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 oftreatments 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 ARTICULATIONThe 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 UnitedThe 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,

settled on full-height fins set at three - apparently random

developed for the fin profiles, which gives an organic feel

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.

COPPER TAKES CONTROL

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.

Copper Clad Volumes

The two main facades are articulated asdistinct, copper-clad volumes aligning withthe typical Mansard-roofed blocks eitherside. The volumes are separated on the westfront by an inset cloak of suspended stainlesssteel mesh reaching up to the penthouse andsignaling the buildings entrance. Copper wasthe architects first choice and its sustainable

credentials a consideration. Opaque claddingis generally pre-oxidised copper, selected forits more regular brown shade than mill finishmaterial.

The defining external features of the newbuilding are vertical shutters clad in perfo-rated, pre-oxidised copper. In conjunction
