OPINION

When is a Spec Not aSpec?

Far better that the industry address this thorny issue itself,while it still can, rather than have some external body impose acontrol mechanism which may be restrictive. Self-regulation is

always best.

There was a time when the specification in relation to thebuilding services on a project was sacrosanct. Once on the spec

a supplier could rest easy, secure in the knowledge that athorough appraisal of the project's requirements had led to thatparticular solution being arrived at. However, that is no longerthe case ... that little phrase"or equivalent" appears to have as

many interpretations as there are opinions.

Price is important and it is vital that clients get value for money.However, going with the cheapest price on the job does not

necessarily mean value for money. Indeed, experiencedemonstrates only too well that, in very many cases, value for

money is forsaken when the cheapest price route is chosen.The imminent enforcement of the Energy Performance in

Buildings Directive (EPBD) will undoubtedly force the industryto take a hard look at itself. It will inevitably highlight - andpenalise - price-led decision-making that ignores the design

objective.

There is no doubt that transparency in the marketplace isessential. However, paying lip-service to transparency without

the attendant honesty and integrity is self-deceiving. Whendecision-makers choose an "equivalent" product to the one on

the original spec they must do so on the basis of a genuine, likefor-like, comparison. There must be a level playing field.

Far too often when the spec is changed it is patently obviousthat the chosen option is not "equivalent" in that it does not

perform the same number of functions, or deliver to the sameperformance levels.

BathroomTrends 2006

Brendan Whooley,Managing Director ofShires, predicts that: "asleek and minimalistaesthetic will continue tobe the hallmark look forbathrooms in 2006. Thebiggest design influence inbathrooms at present is amove towards Europeanstyling and the hallmarksof this trend are interestingshapes, subtle curves andof course the ubiquitousclean lines", he continued.The Catalano range fromShires embodies this trend.

According to Brendan,the hottest trend inbathroom design continues

to be above-counter sinks.While square basinscontinue to rise inpopularity, unique basinsin fresh, organic shapes arealso presenting as hot newchoices. Such basins createstreamlined focal pointsfor modern bathrooms.Shires have a basin to suitevery taste in these styles.

Checl< outthe benefits!At last, a unique control system that provides fiexible, energy

saving air conditioning that's perfect for hoteliers everywhere!

The Mitsubishi Electric Programmable Logic Controller I (PLC) connects to our GSO control systems to providemaximum control for hotels everywhere. By simply programming the Indoor air conditioning units to work in conjunctionwith eXisting key card systems, the PLC achieves the highest level of control.

When the hotel room is:

> Occupied with key card inserted. The air conditioning is initially set to 'Auto' mode and 21 QC 2.

From this point onwards the guests then have full control.

> Occupied with the key card inserted and a window open. When using the optional window sensor,the air conditioning is automatically switched off to save maximum energy.

> Unoccupied with no key card inserted. The air conditioning is automatically set to 'Night Set Back' mode whichmaintains the room temperature between I6QC 2 and 26QC 2.

USing the PLC with our advanced control systems (GSO or Baby GSO), enables all guest rooms to be easily monitoredand/or controlled from a central point in the hotel, ensuring utmost comfort and maximum efficiency throughout.

It also:

> Ensures maximum comfort and efficiency by preventing guest rooms being too hot or too cold prior to occupation.

> Saves energy by avoiding guests inadvertently setting the wrong mode (ie. Heating/Cooling instead of Auto).

CLEAN, SAFE AND EFFICIENT AIR CONDITIONING

USES GAS INSTEAD OF ELECTRICITY

NO CFC's or HCFC's

.s::0::JCl

cDen::JoI"0CoE(5

Innovation • Technology • Environmen1

With the advent of the Energy Performanceof Buildings Directive (EPBD) from the start ofthis year, the need for greater system

efficiencies has created a demand for moreinnovative building services solutions, Indeed, thisnew culture, driven no doubt by the new regulatorycontrols, suggests that a single, efficient, compactsolution for heating and air-conditioning is theinevitable future for most bUildings, There is ofcourse the need also for that solution to beecological, easy-to-install, simple-to-use, andservice. The good news is that such a solutionalready exists.

Gas-Fired Heat Pumps - GasUtilisation Efficiencies up to over 150%There is a common misconception within the HVACsector that all heat pumps comprise electricallydriven compressor devices. That is not the case, TheRobur absorption chiller and heat pump range fromTempar does not incorporate a compressor. It isbased on a single, modular, gas-fired, machinecapable of using renewable energy from theenvironment, with extremely high-efficiency, to heatand cool a building.

The Core Principles Modular • Flexible • ReliableThe basic chiller and heat pump module consists of afully-packaged, gas-fired, absorption machine - in aircooled or water cooled type - that will deliver chilledwater down to a temperature of 3QC and heating waterup to a temperature of 60QC (heat pump heating mode).The chiller module is also available in a version that hasan integrated gas-fired heating section that will deliverheating water up to a temperature of 80QC, and also inanother version that incorporates a heat recovery systemfor simultaneous heating and cooling operation, Thesemachines have no refrigerant compressors installed asthey operate on the "absorption" principle using a smallcharge of ammonia/water mix within a stainless steel,fully-welded, refrigeration system. A small gas burnertakes the place of the conventional compressor. The onlymoving parts are a condensor fan in the case of the aircooled type, and a small solutions pump, Not a lot to gowrong or maintain or that makes noise.

Module Versions- Gas Fired Air Cooled Chiller (19kW Cooling);

- Gas-Fired Air Cooled Chiller with incorporated gas fired heater(19kW cooling/35kW heating);

- Gas-Fired Air Cooled Chillers with Heat Recovery(19kW cooling/25kW heat recovery);

- Gas-Fired Heat Pumps - Air to Water(non-reversible - 36kW heating);

- Gas-Fired Heat Pumps - Air to Water(reversible - 18kW cooling/35kW heating);

- Gas-Fired Heat Pumps - Water/Ground Water(18kW cooling/38kW heating);

- Gas-Fired Air Cooled Liquid Chiller(25% ethylene glycol down to minus 121lC)(13kW cooling at outlet liquid minus lOllC).

Heating & Cooling - 'Tailored'Modules to Meet Clients' NeedsBeing modular, all of the above versions can be"tailored" as required and provided in factory-assembled"packages" to meet specific cooling and heatingrequirements up to a max of five modules per factoryassembled "package". This is due solely to transportlimitations. The modules are provided on a special basewith all mechanical and electrical interconnectionscarried out in the factory. Any number of these factoryassembled "packages" can be linked on site to cater forvery large cooling and heating needs.

Robur - Key Advantageso Uses only natural fluids - ammonia and water - zero

environmental risk;o High energy efficiency - G.U.E.'s of up to 150%;o High reliability, long working Iifespan, constant performance over

time and low noise operation;Minimal spare parts requirement - There are only two electromechanical components;

o Micro-processor control and self-diagnostics system;·t modularity - "Tailoring" of modules to meet cooling/

eating requirements;o No internal space required for boiler plant;o No flues required;o Minimum electrical power requirement - 0.8kW per module.

Environmental Management CertificationRobur's Environmental Management System is certified toUNI EN ISO 14001 :2004. Robur obtained this internationalcertification in recognition of its attention to developing,maintaining and improving an environmental policy andmanagement system in compliance with the principles ofTotal Quality and the rules of international standards.

Robur is one of the first companies in its field to receive thisinternational certification, and it marks an importantachievement for a company which is dedicated to theprinciples of sustainable development, leading-edgetechnology and low environmental impact.

Mitsubishi HeavyIndustries continues tomake advances intechnology and efficiency,with the extension of theKX4 inverter VRFsystems. Both 2-pipe and3-pipe systems are nowavailable, with coolingcapacities up to 136kW.

MHI KX4 VRF systemsoffer many advantagesover standard systems.This latest developmenttechnology provides therequirements of highefficiency, highperformance cooling andheating, together withmany of the itemsrequested by designers,installers, andcommissioning engineers,to facilita te easyapplication, operation andcontrol of these advancedsystems.

For example, allstandard remotecontrollers now have 7day/24-hourprogrammable on/oftimer, with differenttemperature settings foreach operational period. Itis also possible to accessoperational data from theremote controller, makinglife easier for the serviceengineer or site manager.

Compressors are allinverter type, meaning nohigh start currents fromfixed-speed compressors.The footprint size hasbeen kept compact,reducing installationspace and minimisingcosts where steel deckingis required. The largestsingle outdoor unit is now68kW, having a footprintof only nOmm x 1350mm,and connectivity to 40indoor units.

The larger outdoor

units have also beentotally re-designed, withthe compressorcompartment separatedfrom the air-side. Thisreduces noise break outand simplifies service andmaintenance operations.

Reliability is alsoconsiderably improvedwhen there is one, or two,inverter compressorsrunning in tandem. Thishelps to contain the oilwithin the compressor,Significantly improvinglong-term reliability.

The high efficiency isderived from the newdesign of compressors,heat exchangers andrefrigerant monitoringdevices. The "fuzzylogic" technologyconstantly monitors andcontrols the refrigeranttemperatures andpressures throughout thesystem, and ensures thecorrect amount ofrefrigerant is available ateach indoor unit to meetthe cooling or heatingrequirements of theinternal areas.

On the KXR4 3-pipesystems, energy isrecovered from the warmareas of a building, andutilised to provide heatingfor the cool areas, thusreducing running costs.

Blimpinto

Hangar TransformedTropical Paradise

This bird's-eye view of the indoor tropical resort, built in a former blimp hangar near Berlin inGermany, clearly illustrates the need for an efficient water supply system.

When a visionaryentrepreneurdecided to turn

a gigantic blimp hangarnear Berlin in Germanyinto a tropical paradiseresort destination, heturned to lIT Lowara toprovide pump systemsand expertise to powerthe water supply system.Colin Au, a businessmanand entrepreneur fromMalaysia, bought thegigantic hangar wheredirigibles used to be builtand converted it into asort of Prussian tropics,complete with a rainforest of about 40,000imported plants, aBalinese gate, Indiandancers and a "South Sea"beach.

Known as "TropicalIslands", Europe's onlytropical paradise wasopened in December of2004 in the world's largestself-supporting hall. Itcomprises an attractiverecreational area of 6,6,

hectares (66,000 sq m) insize, featuring shows,entertainment, swimming,sports activities, achildren's club, beachparties, restaurants andsouvenirs.

The massive hall 360 meters long, 210meters wide and 107meters high - presentsauthentic tropicalvegetation with 500different plants andallows insights into thecultures of Brazil, Bali,Thailand, Malaysia andKenya. Well-knowninternational interiordecorators, landscapegardeners and botanistshave participated in theproject.

Obviously, with anenterprise of this scale thesupply and managementof water is of paramountimportance. That it alsofeatures a rain forest ofabout 40,000 importedplants and a "South Sea"beach makes it even more

critical. When makingtheir final decision theconsultants opted forpump systems from lITLowara for water supplyand water pressurethroughout the resort.From a seven kilometreslong water pipe a Lowarabooster unit (GT 30 HVSV 4602 F75T series) isused to pump the waterunder constant pressureinto two intermediatereservoirs with a capacityof 300 cubic meters each.

Tropical Islands needs180 cubic meters ofdrinking water per dayand also the daily refillingof the pools, which isdemanded by sanitaryregulations. This dailydemand is supplied bymeans of two verticalmultistage pumps (GT 40HV SV 6603/1 F 150 T/series), with a constantpressure of 6-bar. Bothpumps are monitored by aHydrovar® controlsystem which, by way of

its rpm control, operatesin a very energy-efficientway.

The Hydrovar®control module makes itpossible to compensate forvarying levels of waterdemand by changing therpm. The systems are laidout in such a way thatthey can cover the needsof future outsideexpansion. After a certainrunning time theoperational pumps areexchanged automaticallyso that the load is equdistributed among thereserve pumps as well.

The water supplysystem is integrated intothe central control systemof the Tropical Islandsresort through a collectivemalfunction notice. Thesystem controls regardingpump-in-operation notice,running time, waterpressure and watervolume, are computerisedand operated by theemployees.

The resort has its owpower station with a ,<apacity of 2 x 3.5 MWthat supplies heating andenergy. Thus, an overallair temperature of 25-28°Cis maintained, in someparts even up to 35°C. Thetemperature of the 6000cubic meters of water is28°C (in the "South Sea")or 32°C (in the "Lagoon").The tropical ocean'ssurface amounts to 4000sq m but this is set togrow further by theaddition of an outsiderecreational area of 500hectares (five millionsqm).

Mechanically thebuilding is heated by acombination of underfloorheating on the basementand ground floor, whilelow surface temperatureradiators provide spaceheating in the offices andapartments.

The retail and cafeareas, along with thebasement storage area, are

heated by two manifoldssupplying a total of 24underfloor heating loopsembedded in the screed.Their heat source is three120m-deep bore holesdrilled at the outset of theproject. The three circuitsare looped through to aheat pump which is ratedat a COP of 3.

The heating system isoperated on two separateheaders which are linkedby an injection circuit.Typically the buildingsspace heating and waterheating will beaccommodated by theGreen header which is fedby the heat pump. Thisheader operates at a DeltaT 45°C. Should thebuilding demand be in

excess of the heat pumpsupply, a high-efficiency,low-energy, gascondensing boiler will actas back up.

Hot waterrequirements for thebuilding are met by thesix solar panels (17.5sq m)which are integrated intothe buildings upperreaches through purposemade balconies. All toiletson the project are dualflush concealed cistern

type which are fed froman individual tank in theplant room. This greywater tank collects waterform the grass roofs alongwith surface run off fromthe cafe forecourt.

The installed BMSsystem will be used foraccurate metering andmonitoring of this highlyefficie).1t building whichstands as a model forfuture buildingdevelopment. However, itwill be 12 months or sountil sufficient data hasbeen accumulated fordetailed analysis todetermine precisely justhow "green" the buildingis now.

outside their day jobs to contributesignificantly to the very full andtop-rate CPD programme operatingin Dublin, Waterford and Cork. Thecommittee is a great mix ofexperience and youth. They are alsoa very nice bunch of people t workwith", Kevin enthuses.

CPD events are divided evenlybetween mechanical and electrical.However, with an increasingnumber of events in sustainableengineering effectively crossing thedivide, the entire programme is ofinterest to all. Indeed, such is theimportance of sustainableengineering that CIBSE is hostingan international conference onSustainable Engineering in Dubon 9 March next.

In Dublin the mechanical eventsare generally held on the lastThursday of the month in Bolton Stwith electrical on the first Thursdayof the month in Kevin St. "We seemto have finally raised the status ofelectrical services", says Kevin."People now realise it is more thana few lights and sockets. Evidenceof this is in the tremendous successof the Electrical ServicesEngineering programmes in DITKevin St. They have an excellentteam who respond to the demandsof students and industry withinnovative student-centredprogrammes on a part-time, asas a whole-time, basis.

"There' are 150 electriciansstudying for degrees at present onan accelerated programme thatrecognises their prior learning.Likewise in Bolton St the highlysuccessful Building Servicesprogramme is being re-accreditedby Engineers Ireland as a fully-

not have gotten elsewhere".As Head of Learning

Development for the Faculty ofEngineering, Kevin is in a goodposition to judge. He cites DITPresident, Professor Brian Norton (aCIBSE Honorary Fellow) whoproudly proclaims DIT as thelargest third level institute inIreland. There are a total of 22,000students, 8000 of whom areapprentices and 4000 are part-timestudents. "We are especially proudof our multi-level status coveringapprentice courses to post doctoralresearch", says Kevin.

Throughout his career Kevin hasalways been a staunch supporter ofthe CIBSE and he is currently the23rd Chair of the Republic ofIreland Branch. He is enjoying hisyear in the hot seat but stresses thathe would not have been able to takethe job on were it not for the qualityof the present committee, the thecontribution of his predecessors.

year old apprentice electrician.When he completed hisapprenticeship he entered VarmingMulcahy Reilly Associates to beginhis training as a design engineer. Atthat time there were no electricalservices engineering graduates soVMRA hired electricians who werecontinuing their education at night.He went on to work as an engineer'with McGrattan & Kenny beforebecoming a wholetime lecturer in1983.

"I was teaching part-time inKevin St while working withMcGrattan & Kenny but I saw theeconomy going into depression in1983 and, with a new mortgage andinterest rates at 16%, I thought Ibetter get a secure job ", he laughs.

Kevin first entered the College ofTechnology in 1971 on a blockrelease apprentice course and now,35 years later, is researching for hisDoctorate in the Dublin Institute ofTechnology (DIT) as it is nowknown. "The DIT is now a vastlydifferent place from what it wasthen but it afforded me and manyothers opportunities that we may

Kevin takes up the point:"Ireland now has the fourth highestGDP in the world. We are no longerthe beggarman described by theEconomist magazine in 1987.Ireland had the highest levels ofgrowth in the OECD in the 1990saveraging over 6%. It is hard tobelieve that we had unemploymentlevels of 15% as recently as 1993.

"The Irish economy has changedwith globalisation to a knowledgesociety and a modern companymust ensure its knowledge base isexpanded so that it can meet thedemands of the changing externalenvironment. For this reason it isimportant for companies to supporttheir staff as they seek to updatetheir knowledge, enhance theirqualifications, and research areas ofinterest to the sector."

That said, Kevin cautions againstbecoming complacent. "Manyyoung graduates have only knownthe good times but, with one of themost open economies in the world,Ireland is susceptible to a shockfrom outside. A downturn in the USeconomy or a change in theircorporation tax for multi-nationalscould have serious implications.

"Companies and engineers caninsulate themselves by ensuringthey learn as organisations andindiViduals. The DIT has devisedinnovative programmes which willallow them do just that, and alsoenable them to respond to societalneeds and the increasing numbersof staff required to be involved inresearch.liThe future for the building servicessector looks good thanks to thecombined efforts of the DIT and theROI Branch of CIBSE", concludesKevin.

Island communityenergy supply networks such asthat developed by Woking BoroughCouncil in the UK provide a leadfor research and development inthis country that will be a challengeto engineers.

According to Kevin, all of this iscreating a demand for researchengineers and opportunities forpost-graduate degrees. He believesthat higher education must respondto these needs with appropriateprogrammes suited to the needs ofindustry and working engineers.

As BSNews interviewed Kevin inhis office in DIT, Mike Murphy, theDirector of Engineering, droppedinto the office. Mike was

enthusiastic about developments inboth electrical and buildingservices departments andcommented in this regard. "We aredeveloping post-graduateprogrammes in response to demandfrom industry", he said, "along withpart-time masters programmes inenergy management and buildingservices which are delivered in aflexible format. This will helpengineers meet new challenges aswell as increasing their academiccredentials for the new economy."

semesterised and modularisedprogramme with emphasis onstudent learning outcomes. Thereare also good-quality programmesoperating successfully in the CorkInstitute of Technology. Thebuilding services industry is luckyto have such high-quality graduatescoming through".

The central focus for the CIBSEcommittee this year is theSustainable Engineering conferencescheduled for this coming March.Venue is Clontarf Castle in Dublinand the speaker line-up comprisesrecognised experts in theirrespective fields (see pages 42 & 43).

ustainable Energy Ireland is verynuch a pro-active partner in this

venture and there will also be ahigh DIT involvement.

Kevin explains that the speakerline-up will reflect the dissolvingdemarcation lines betweenmechanical and electrical as thechallenges of the modern economydemand a holistic approach tobuilding design. "If we are to meetthe challenges of Kyoto", he says,"then we have to design, build anduse our built environment in asustainable way so as not to denyfuture generations their share of the

Increasing the use of renewableenergies, reducing energy used inbuildings with passive cooling andinnovative alternatives, increasingthe use of combined heat andpower are all to the fore now for theindustry. This is already having aneffect with many modern energyefficient buildings designing out airconditioning. Nuclear energy, with

there are many examplesof successful prototypedesigns of fuel cellpowered motorcycles,automobiles and buses(fuel cell history website_http://rmi.org/)).The Chinese DalianInstitute of ChemicalPhysics (DICP) presenteda 30kW PEM fuel cell busin December 2002.

A principal challengeis the design of a reliable,safe and compact system,which may be used topower either a stationaryapparatus or a mobileunit such as a wheelchair.

Alkaline fuel cells(AFC) operate oncompressed hydrogenand oxygen. Theygenerally use a solution ofpotassium hydroxide KGH in water as theirelectrolyte. Efficiencies ofup to 70% are possiblewith operatingtemperatures up to, andexceeding, 150°C. Inpower rating, cell outputranges from 300W to 5kW.
