RISING UP FROM THE SITE OFTHE DEMOLISHED TIVOLI CAR PARKin the Melbourne CBD is a project that willestablish a new benchmark for environmentallysustainable architecture in Australia. Whencompleted, the Council House 2 (Ch2) projectwill be the first Australian building to achievea Green 6 star rating under the Green BuildingCouncils Green Star rating system. The City ofMelbourne’s vision for its new administrationbuilding is to create a real example of thebenefits of sustainable design, both in terms ofpreserving the environment and in terms of

long-term cost savings. The CH2

project has been called the mostsustainable office development in Australiaand will be recognized as a world leader insustainable design.

For such an ambitious project, the City ofMelbourne engaged Australia’s fifth-largestconstruction company, Hansen Yuncken.Established in 1918, Hansen Yuncken is anAustralian-owned company with an annualturnover in excess of $520 million andemploying approximately 400 staff. Hansen

Yuncken’s motto is ‘“Building Value’” andover the years they have built a strongreputation based around quality and buildingintegrity, with the aim of creating value fortheir customers.

Hansen Yuncken Project Manager for theCH2 project Mr. Paul Bolton says, “Our aimis to build value for the client by workingwith them to achieve the best possibleoutcome we can”.

Hansen Yuncken has a strong tradition ofbuilding environmentally sustainable projects

and has developed a reputation as a premierdeveloper of “green” projects in theMelbourne area. The 60L project in theMelbourne CBD, built by Hansen Yuncken,was one of the first major “green” buildingsin Melbourne. In addition, the K2development for the Victorian Governmenton St. Kilda Road will achieve a Green Star 5rating. The company’s experience withenvironmentally sustainable projects madethem the perfect candidate for the City ofMelbourne’s CH2 project.

Shading Systems of Australia

MIGLAS WINDOWS a clear environmental vision

THE NEED TO DEVELOPNEVER BEFORE SEEN manual andautomatic shading systems, some with full-loopmotorised control, and provide anenvironmentally friendly product in the process,meant that Shading Systems of Australia was theperfect shading solution supplier for CH2.

The company, which has a strong andrespected, component engineering and designbackground, was the first choice to provide theshading system requirements for the 6 greenstars Melbourne project. Shading Systems’specialist expertise, and its particularexperience in developing new products fromarchitectural briefs, set it apart from itscompetitors. Having worked within thebuilding, construction, architectural andinterior design industries for many years,Shading Systems of Australia has vastexperience in developing specific shadingsolutions for unique and difficult assignmentsincluding glazed areas in both vertical facadesand horizontal roofs for the shadingrequirements of the new wave ofenvironmentally conscious developments.

It was in fact ShadingSystems’ uniqueexperience in workingwith environmentallysound materials anddeliveringenvironmentallyfriendly products thathelped the companysecure the coveted CH2contract. Workingclosely in conjunctionwith French textilemanufacturing company

“Ferrari”, Shading Systems has employed anenvironmentally sound, specially coated andwoven polyester radiation screen to be the firstline barrier in controlling solar radiation.

WORLD FIRST – TIMES THREE

Peter Scrivenor, Technical director of ShadingSystems of Australia, says “to satisfy all thecriteria for the designers and client, we actuallystarted from scratch to develop 3 “first of theirkind” products especially for CH2.

The first of these is an external, permanentlyfixed, “light shelf in-fill”. These areprefabricated aluminium frames designed toneatly insert into the steel framework to beinstalled above each North facing balcony.Comprised of a series of decreasing size,removable shading panels, Shading Systemswill fill these frames with the special Ferrarienvironmentally friendly textile.

The second product Shading Systems hasdesigned for CH2 is a moving “targeted shadepanel system”. Using a unique and exclusivesystem, this mechanism will operate a movingpanel of shade fabric up and down a series ofsteel guides to provide adjustable “targeted”shade to the internal office areas concentratingon the specific layout of seating, desks, VDU’setc. within the office depending on the intensityof light and the time of day. In an excitingworld first development, Shading Systems willsupply this product into CH2 with a number offull loop controlled motorised versions toprovide shade at the top, bottom andintermediate levels of the large, lower windowsfor CH2’s North façade that are fully integratedinto the BMS and for the very first time willprovide complete positional feedback to themain computers (that are controlling lighting

and air conditioning) delivering the world’s firstgenuinely fully integrated shading system.

The final product developed for CH2 by theShading Systems team, is a unique internalroller shading system that operates from ahidden location in an upwards direction.Extending above the aforementioned targetedshade panel mechanism, this will provide theshade for the upper section of all the externalwindows on the North of the building.

The CH2 project, with its unique requirements,has provided many challenges for the ShadingSystems of Australia design team. With itsbackground in component engineering anddesign, as well as complete Shading Systeminstallations, the company has been able tomeet these challenges and develop excitingnew products for what is to be Australia’sgreenest building.

MIGLAS WINDOWS WASESTABLISHED IN THE EARLY 1970’S BYWALLY MIGLAS as a family joinery business.The business evolved and developed and wascontinued on by his son Anatol Miglas.

Located in new premises in Montrose Victoria since1985, Miglas specialises in window design andmanufacture. The company boasts the latest, state-of-the-art machinery, guarantee a consistent product andcontinue to develop innovative, sustainable designs.

“All the products are designed in-house and we arecontinually improving the design and constructionmethods. The result is a product that we believeoutperforms anything in the market under NATAapproved laboratory tests. Recent tests on our AliClad window exceeded 2000 pa of water pressure”said Mr. Miglas.

As well as producing high quality products,environmental sustainability is an important part ofthe company philosophy.

Miglas manufactured and supplied the specialisedwindows for the CH2 project. Mr. Miglas said thatno other window manufactures could meet thestringent requirements for timber windows in the 10storey environmental, sustainable development.

One of these requirements was that the timber wassourced from re-growth forests.

“All timber, for every project, is sourced fromsustainable re-growth forests. The native timber isprivate or state forests approved by the VictorianDepartment of Natural Resources and Environment forselective logging of re-growth timber.” said Mr. Miglas.

Miglas are continually developing their products withthe environment in mind. Recently the company wasselected to manufacture and supply windows to twosustainable housing developments – K2 in Windsor,Melbourne and Walford Terraces in Hobart.

DESIGNINCWHEN CH2 IS COMPLETED

IN EARLY 2006, the six green starMelbourne development will set a newstandard in Ecologically Sustainable Design.The building, created through an intensivecollaboration between the City of Melbourneand DesignInc, represents more than just thehuge benefits of environmentally soundbuilding practice.

In addition to being a stunning andenvironmentally sustainable multi-storeybuilding, CH2 will be a tangible illustrationof the benefits of an integrated designprocess. Stephen Webb, Design Director atDesignInc says that the multi-discipline firm,which has expertise in architecture, interiordesign and urban design, has a strongculture of collaboration. According to Webb,for DesignInc, a good idea is a good idea,no matter where it comes from. This, andthe firm’s strong focus on reconcilingnatural, social and economic buildingimperatives, made it the logical choice tocollaborate on CH2.

And the collaborative approach involved alot more than the traditional brief from theclient. Working with the City of Melbournein-house design team and AdvancedEnvironmental Concept (AEC) Engineers, afortnight-long workshop was staged to teaseout and develop the core ideas of what CH2

should become. The experience wasinvaluable. According to Webb, working inthe group saved significant time on theconceptual design of CH2. This enabled thewhole team to trial prototype innovationsand deliver the architectural plans for theproject in a time frame that designers of aregular building would find challenging.

The collaborative approach had other benefits aswell. Webb points out that working with such amixed team encouraged a free flow of ideas andincreased the chance of coming up with newinnovations. This is especially important in thegrowing area of Ecologically Sustainable Design.As Webb points out, the workshops facilitatedthe creation of customised integrated solutions.Much was gained as participants, includingarchitects, engineers, artists, environmentalexperts, future occupants, the CSIRO and theSustainable Energy Authority, sparked newconcepts off each other. Ideas for novel ways ofdoing things were forged, and with the help ofDesignInc, will take form in early 2006. Webbsays that the collaborative approach wasinteresting from a technical perspective, as itfostered the developments of key CH2 featuressuch as ceiling panels that incorporate air-ducts,manage acoustics and regulate floor ventilation.

Giving life to the ideas of the workshop andregular follow-up design sessions needed ateam that could manage such an influx of

ideas. It needed an architectural firm thatcould bring the complex goals together and setthem to paper. DesignInc thrived on thechallenge. Utilising its experience inecologically sustainable design and inter-disciplinary collaboration, the architectural firmwas able to help create a building thatharvested sunlight, night-air, water, wind andrain. Moreover, it helped create a refreshinglyenvironmentally attuned building that will notonly minimise environmental pollution bothduring and after construction, but will add newvibrancy and cultural life to Little Collins Street.CH2 will be a landmark for years to come.

AS A COMPANY WHOSEVISION IS TO BE THE WORLD’SLEADING FAÇADE CONSULTANT,Meinhardt Façade Technology (MFT) may beclose to achieving its goal. The companyrepresents the façade design andconstruction arm of the Meinhardt Group, amajor engineering consultant with a staff ofover 1000 in 12 countries and fourcontinents. Utilising the latest technology,MFT’s Managing Director Tony Alvaro saysthat the company’s mission is to deliver aprofessional and a superior service to clientsand always striving to be the leader in façadetechnology.

The company offers a number of servicesassociated with façade consultancy andremedial engineering, including risk analysisand budget factoring. Specialising in theexterior envelope of commercial high-rise andlow-rise buildings, MFT provides consultancyservices for glass walls, windows and curtainwalls of various shapes and materials, somestunning examples of which can be seenacross Asia and the Pacific region.

One of MFT’s current projects is the CH2building in Melbourne, a project thatdemanded creative solutions in line with theecologically sustainable design (ESD)imperatives outlined by the Client. MFT wascalled in by Builder- Hansen Yunken to be theconsultant to design the exterior timberwindows and glass walls. Mr Alvaro stressedthe innovative nature of the task:

“For a multi storey building, the use of timberwindows was totally unique. The use of glue-laminated (glulam) timber windows enhancedthe integrity of the project’s green-orientedinitiative on manyfold.” He said. In addition tothe intrinsically rich aesthetic and the ecologicalbenefits of re-using materials, the solid recycledtimber presented several design challenges tothe team at MFT. Unlike the metal-framedwindows commonly used in commercialconstruction that sit hard against slab, theobvious problem with timber windows was todesign an interface that allowed for themovement of the building. The solutioninvolved developing a movement joints at thehead to allow for flex of the building andadequately weather proof the interface”.

“Commercial windows are a complexarrangement of components with contrastingrequirements for strength, tolerance for buildingmovements and as a barrier against weather.The normally, accurate performance predictionssolely from design calculations are not sufficientin this case. Prototype samples were built andlaboratory tested for structural engineeringcompliance and for water and wind ingress toensure a durable and satisfactory outcome”.

“The window frames were manufactured outMountain Ash glue-laminated (glulam) timbersections. Sections had to be glue laminated sothat off-cuts and smaller lengths of timbercould be assembled to form the large frame.Whilst the properties of Mountain Ash are welldocumented, the structural properties of theglulam timber, in terms or strength and

stiffness cannot be assumed to be the same asthe timber, hence there was the need forstructural testing”.

“The timber tests involved structural testing ofglulam timber section to asses the structuralproperties of the timber and thereafter testwholly assembled prototypes. Based on thestructural properties assessed from the tests onthe timber sections, theoretical and finiteelement studies were carried out and the resultsof which then were compared with thebehaviour of the prototype under the designwind actions. The water and wind ingress testshelped MFT to fine tune the flashings andsealing of the window and at the same timeallowing the connections to accommodate theanticipated building movements. MFT inconsultation with the timber suppliers, windowmanufacturers, testing laboratories developedappropriate specifications, procedures andmanaged whole the testing process and design”.

At time of writing MFT is engaged incontinuously monitoring the installation on sitefor compliance to the strict QA procedures asthe project nears completions.

Reeds Consulting Pty Ltd

THEBONACCIGROUP

WHEN CH2 IS COMPLETEDIN EARLY 2006, the project being hailed asAustralia’s most sustainable office buildingwill be remarkable for more than its much-vaunted 6 green star rating. CH2 willsymbolise a huge feat of effectivecollaboration between a diverse green teamincluding engineers, architects and builders.One of the main collaborators on the LittleCollins Street development is ReedsConsulting Pty Ltd.

In business for over 45 years, ReedsConsulting employs a small team of only 42.It nonetheless packs a pretty mean punch.Specialising in land surveying, civilengineering and development consulting,Reeds involvement in CH2 came about whenit was recruited by Melbourne City Council tocreate the site at 218-242 Little Collins Street.

Work on the CH2 project begun with Reedsre-aligning the property boundaries forcouncil. Easements were established,boundaries for air space were created andunderground boundaries were amended.Working with the builder, Hansen Yuncken,Reeds then supplied base information andcontrol to ensure that the 10 storey CH2 was

built correctly on the site in accordance withthe design.

Reeds expertise and experience in high-risebuilding subdivision and land development iswell known. This, and Reeds reputation forhigh-quality customer service and efficiency,was one of the main factors that helped theconsulting company secure the CH2 contract.

A spokesman for Reeds says, “our philosophyis that our interests are governed by ourclient’s best interests”. This means usingsophisticated electronic measurementequipment and CAD programs, as well asmethodically reviewing procedures to meetclient’s stated and implied aims. Reedscommitment to providing its clients with thebest service possible extends beyond theusual customer service rhetoric. Reedsmonitors changes in statutory acts andregulations whilst pursuing an innovativedesign policy. In fact, to maintain quality,Reeds constantly works to review andincorporate into its practice technologicaladvances and new work practices.

Although Reeds typically bids on landdevelopment and high-rise sub-division, it

also provides particular expertise in otherareas of land surveying and civil engineering.Reeds is an accredited service provider towater companies, municipal councils,VicRoads and an array of utility andinfrastructure groups. Reeds providesparticular expertise in engineering services ininfrastructure and urban renewal projects. Italso offers expertise in residential, commercialand industrial land subdivision and surveyworks. In addition to this Reeds offersproject analysis, including feasibility studiesand analysis of the financial management ofprojects. In land surveying Reeds offersexpertise in title boundaries and duediligence as well as topographic, engineeringand construction surveys.

Reeds involvement in the CH2 project istestimony to the company’s focus oncustomer service and quality products. ForReeds, CH2 is another feather in a cap that isalso decorated with projects such as theEureka Tower, the Commonwealth GamesAthletes Village, the TriBeCa East Melbournere-development of the old Victoria breweryand the Concept Blue redevelopment of theformer police headquarters on Russell Street.

AT THE HEART OF THE CH2CONSTRUCTION WAS THE CUTTING-EDGEwork of the Bonacci Group, appointed to carry outthe structural and civil engineering requirements.With a well-earned reputation as innovators in theirfield, Bonacci's 24 years of international achievementequipped them with the technical resources to reallystrut their stuff in a landmark project.

Mr. Roger Sykes, an associate of the group describedhow the design process evolved: "In the first twoweeks, intensive workshops were held in whicheveryone involved contributed perspectives whichwere thrown into the mix. One of the outcomes wasthe actual changing of sites from CH1 to the carparksite next door, a more practical option." Mr Sykeswent on to say "At the time of the design's inception,it was a leading edge situation for us in terms ofrequirements to meet green-star ratings. Factors thatcame into consideration included materials and awhole range of systems within the building. Theseeffectively drove the shape of the structure," he said.

Bonacci was responsible for designing andcommissioning the revolutionary wave-shapedceilings, which are a crucial component of the greendesign's emphasis on the fusion of 'form andfunction'. The ceilings are 180 mm pre-cast concretepanels creating channels which provide 'passive'cooling when set against the flat slab above, and'active' cooling from the chilled beams housedwithin. Into these panels is built the wall formwork,which in turn form up to the primary beamproducing a stunning example of integrated design.

Another section of the project which benefitted fromBonacci's expertise was the constructed steelworkfacade which supports the external balconies on alllevels. One of the benefits of these 'aerial terraces' isthe accessibility to fresh air - workers are spared theclaustrophobic environment experienced inconventional office buildings. The steelwork also actsas a framework for the ingenious 'vertical garden' onthe northern wall, which in itself is another link inthe wholistic approach to controlling the air qualityand temperature of the interior.

Meanwhile, Bonacci's continued presence in theinspection phase of the work successfully bringshome the quality of service that has built theirreputation as industry heavyweights. Their creativeresponse to the shared vision of a greener future forthe construction industry adequately justifies theircorporate motto, 'The Art of Engineering'.

In addition, Hansen Yuncken has beeninvolved with many large-scale and iconicprojects in Victoria and around Australia.Recent projects include the Royal DentalHospital in Swanston Street and theredevelopment of parts of the State Library ofVictoria. The company was also the headcontractor for the new Adelaide AirportTerminal, the new Commonwealth Law Courtsin Adelaide and the NSW Schools Project,encompassing seven new primary schools.

The CH2 project is located on Little Collins St.in Melbourne and includes ten storeys aboveground and three basement levels. Thebuilding was designed by the City ofMelbourne in conjunction with leadingMelbourne architectural firm DesignInc andhas a cost of $51 million. Hansen Yunckenwas required to develop innovative solutionsto build the ambitious project, which willinclude many unique features. The buildingwill require 87 per cent less energy than theexisting administration building and willproduce only one-fifth of the greenhouse gasemissions. The contract time for the project is23 months and completion is anticipated inJune 2006, with Hansen Yuncken commencingwork in January 2004. The building hasalready won a Green Building Award at theUnited Nations Association of Australia WorldEnvironment Day Awards 2005.

Hansen Yuncken had to develop totally newinstallation methods for the recycled timbershutters and Australian hardwood windowsfrom sustainable forests that are used on theCH2 project instead of the more commonaluminium windows. The building is relianton passive heating and the HVAC (heating,ventilation and cooling) systems have been

developed with energy conservation in mind.The building also features glazing positionedto control the building’s internal temperature.

The new administration building will reducethe council’s current consumption on mainswater by up to 77 per cent. The projectincludes a blackwater treatment plant thatwill recycle sewage drawn from on site andfrom the main sewage system in the streetand is capable of processing 100,000 litres aday: “The building will produce more waterthan it actually uses,” said Mr. Bolton. Thiswater will be used in the building forflushing toilets and watering gardens, andwill also be used in council-owned fountainsand for street cleaning.

In addition to this, the CH2 project boastschilled ceilings, PVC-free cabling, phase-change materials used for cooling and anautomated façade system powered byphotovoltaic cells to control light penetration,along with many other associatedtechnologies that contribute to the overallefficiency of the building. Both new andestablished techniques have beencomprehensively integrated and the intentionis that during the building’s lifespan, buildingsystems can be replaced or upgraded withnew Ecologically Sustainable Design (ESD)technology as they become obsolete.

The building’s lifespan is indefinite- theintention is to construct a building that willnot need to be demolished. Given that areasonable estimate of the lifespan of anaverage commercial building of comparablesize would be about 20-30 years, the costsavings from not having to replace thebuilding every few decades more than offsetthe additional construction cost. In any case,

the additional costs building’s innovative andoften unique technologies are expected bepaid off within ten years. The CH2 Study andOutreach program aims to significantlyinfluence the building and related industriesand raise awareness of sustainable designopportunities through consolidated researchand investigation.

The City of Melbourne has made a long terminvestment with the CH2 project that isexpected to pay off. “They’re trying to showthe commercial sector the advantages ofbuilding a project of this type, that it’sworthwhile spending the extra money,” saidMr. Bolton. “It’s the way of the future- it’s goodfor the environment and good for business.”

When completed, the Council House 2 projectwill stand as testament to Hansen Yuncken’sability to complete challenging and innovativeprojects, and will enhance their reputation asa world leader in the construction industryand in sustainable design. Hansen Yunckenhas demonstrated their ability to provideappropriate and innovative solutions,maintaining their commitment to quality andcost-effectiveness while maintaining theirclient-friendly attitude. One of HansenYuncken’s strengths is the enthusiasm of theirwork force. “In 25 years, this (the CH2

project) is the biggest and most unusualchallenge I have faced,” said Mr. Bolton. “Ican’t wait to see it finished.”

Arden Building Maintenance

TAC Pacific

CH2’S SPECIAL ENVIRONMENTALREQUIREMENTS POSED AN UNUSUAL DILEMMAfor the painting of the 300 window Melbourne development.These special requirements, however, posed no problem forArden Building Maintenance.

Taking the unusual step of painting all of the timber windowframes off-site, Arden was able to complete the mammoth taskat its Melbourne factory base. Alan Maden, painting divisiondirector at Arden and formerly of Dulux, brought untoldexperience and expertise to the project. Liasing with the factorymanager, building contractor Hansen and Yunken and others,Dan Saric supervised painters and lent valuable technical skillto the curious assignment.

Alan said the new way of working provided many benefits toboth client and contractor. According to Alan, painting thewindow-frames off-site meant that Arden could set-up fasterand be organised in a way not possible in on-site projects.Notably, painting at the factory meant that Arden did not haveto worry about floor-to-floor access and working around othercontractors. Similarly, as the windows were painted at thefactory, both sides of the frames could be painted at once andArden did not have to gain outside building access.

Arden’s work on the CH2 project was not, however, confinedto its factory activities. In addition to painting the 300 timberwindow frames with the environmentally friendly water basedWattyl Solagard, Arden also painted the outside of CH2.Using the new environmentally friendly Timbermate product,Graffiti Defence, Arden graffiti-proofed the soon to becomplete 6 star landmark.

The project was unusual for Arden, who normally specialise inpainting hospitals and schools. Arden’s success in completingthe six-month assignment on time and in atypical conditions isa credit to the company. It reflects the advantages Arden’sskilled team of experienced painting professionals bring to topend projects.

MELBOURNE’S COUNCILHOUSE 2 (CH2) PROJECT is fast takingshape and the developer, Hansen Yuncken,has contracted TAC Pacific to provide buildingmanagement and security systems for theproject. The aim of the Council House 2project was to develop a building that wasstate of the art in terms of both environmentalsustainability and technological innovation,and TAC Pacific provided a highly integratedmanagement system that is integral inachieving these goals.

TAC Pacific was founded more than 30 yearsago as a small Australian company and is nowpart of the Schneider group of companies,with more than 100,000 employeesworldwide. They have branches in every stateof Australia and specialize in providingbuilding information technology andmonitoring systems compatible with bothmajor industry standards, Echelon’s LonWorksand ASHRAE’s BACnet.

TAC Pacific’s Victorian branch is involved inmany large scale and iconic projects- recentlythey have been involved in the RACV Clubdevelopment and the QV project, both forGrocon in Melbourne. They have worked withHansen Yuncken before, notably on theheadquarters of the Australian Antarctic

Division in Kingston, Tasmania. Theirinvolvement in the Council House 2 projectcommenced one and a half years ago and isdue for completion in May.

The company’s involvement in the CouncilHouse 2 project comprised buildingmanagement and security. The securitysystems installed utilised closed circuittelevision (CCTV) technology. The buildingmanagement systems included electrical loadcontrols and controls for heating, ventilationand cooling (HVAC) systems. The companyalso installed an automated façade system withautomatic blinds and shutters to control lightpenetration into the building. The projectincludes monitoring systems for electricity,water, sewage, gas consumption and otherbuilding systems.

The focus of the Council House 2 project ison environmental performance, and thebuilding was designed with attention toenvironmental sustainability. “It’s quite aspecial building,” said Mr. Peter von Hofe,Project Manager at TAC Pacific. All the cablingused by TAC Pacific on the project was PVCfree. The building is capable of preservingwaste heat for use in the HVAC system, andthe building is capable of monitoring andadjusting airflow to automatically maintain

acceptable CO2 levels. Data from TACPacific’s monitoring systems is recorded foruse in CSIRO research projects.

Building management systems are complexand this was no different. The unusualconstruction methods used for the CH2 projectmade installation especially difficult. TACPacific had to resolve the logistics ofinstallation to provide an integrated controlsystem and the result, as with the rest of theproject, is of the highest quality. "This wasvery much a team effort", said Mr. von Hofe."TAC worked with all parties to demonstrate asuccessful outcome at handover to the client,and to achieve the right balance ofsophisticated energy management and ease ofuse for ongoing building operation"
