Grim … but youcan bear it!

There’s no denying that 2010 has started with a whimper,for construction in general, and building services inparticular. While many returned after the Christmas

break vowing to get stuck in and carry on regardless, theirenthusiasm floundered on foot of the severe cold snap.

But this was merely a minor blip. With the world economyand even our nearest neighbour now officially out of recession,Ireland too can take heart … we will feel the benefits over thecoming months.

Moreover, most companies still trading are far leaner thanbefore with their overheads reduced to the bare minimum.There have been unfortunate job losses over the last six tonine months but, once the situation begins to improve, firmswill be in a position to re-hire many of those let go.

Even the old bug-bear of late payments seems to have takenon a new twist. There is anecdotal evidence to suggest thatschedules of deferred payments are becoming morecommonplace, with companies genuinely cooperating with oneanother to see out these difficult times.

So, while the trading environment is undoubtedly verydifficult at present, there are some very positive signs of amaturing marketplace. When things improve — and theydefinitely will — the industry will be well positioned to benefit.

In the meantime, it’s not so much a case of “grin and bear it”but rather a case that, while it is grim, we can bear it byworking together. �

Advanced TechnicalProducts has introducedthe new Peltier heaterrange to complement theMINIB range of trench and floor-standing heatersfrom S&P Coil Products(SPC). It comprisesperimeter convectorswhich use the heat energy stored within thecirculating fluid to poweran integral fan.

The units are availablein a range of sizes from1m to 2m lengths, andcan be floor-mounted orwall-mounted. The MINIBfloor convectors are thefirst direct space heatingdevices which usethermoelectric technologyto power their integralfans. As a result, theoutput per linear metre of heating element isapproximately double that of a conventional

unpowered, naturalconvector unit.

A small portion of thehot water supplied to the heat exchanger is by-passed through smallbore pipes which arebonded to an array

of series thermoelectricdevices running the lengthof the convector unit.

Peltier perimeter heaters Solar energy photovoltaicapplicationsProfessor Brian Norton, President of DIT and a researcher of solar energy, delivered a veryenlightening and entertaining lecture in DIT Kevin Strecently as part of the joint CIBSE/IET lecture series.

Professor Norton gave a comprehensive overviewof the potential for solar energy photovoltaicapplications and left the audience in no doubt that,properly harnessed, the sun has to be one of themost obvious routes to sustainable energy use.

He supported his presentation with an excellentpowerpoint presentation, the image boldly proclaiming“The earth receives more energy from the sun in onehour that the world uses in a year” saying it all.

Hoval extends UltraGas range Hoval has extended the capacity of its high-efficiencyUltraGas condensing gas boiler range to 1MW. SingleUltraGas units now offer capacities from 50kW to 1000kW,while twin UltraGas units offer outputs from 250kW to2000kW complete with common flue and optionalpipework/header kits.

Featuring Hoval's Ultra Clean combustion system, theboilers use a modulating pre-mix down-firing burner with upto 6:1 turndown (12:1 on twin units) and a stainless steelcombustion chamber with a single pass aluFer tube heatexchanger.

The aluFer tubes are also made of stainless steel with analuminium alloy finned internal surface to provide a highsurface area for heat exchange.

Independent testing (to DIN EN 676) confirms the averageNOx emissions of the boilers are less than 40 mg/kWh —achieving the maximum BREEAM rating of three pointsrelating to NOx emissions.

Net efficiencies of up to 109.5% are achieved when testedto the requirements of the European Boiler EfficiencyDirective, with CO levels of 10 mg/kWh.4

Arctic methane emissionstimebombHaving recorded a massive spike in the amount ofmethane emissions from the Arctic, scientists fear themelting permafrost is a timebomb which will overwhelmefforts to tackle climage change.

The permafrost has billions of tonnes of methanelocked away but, with rising temperatures, this is nowbeing released. Unfortunately, this in turn is speeding upthe rate of global warming and thus speeding up the rateof methane release.

Scientists fear this is a vicious circle which, if leftunchecked, will push the Arctic to tipping point.

Up to 60% of architects lose jobs Three in five employees (60%) in architectural companies have losttheir jobs since 2007, according to a comprehensive survey of theprofession by the recruiting firm Hays.

The Architecture In Ireland Employment Report by Hays clearlydemonstrates that architecture has felt more than its fair share ofpain during this recession, with one practice reportedly shedding 168 out of 180 jobs.

A total of 178 architectural firms responded to the survey whichwas carried out at the end of last year. Between them they employed2,306 people in 2007 but that number had fallen to 945 by the end of 2009.

It’s not all bad news though — 43% of firms surveyed said thatdespite the massive lay-offs, they expected to recruit again within the next 18 months. Of these, many reported that they will re-hirestaff that they have made redundant.

According to the survey banks also posed a problem for architectswith 70% of firms indicating they had projects in the pipeline whichwere being held up due to lack of finance.

Wilo Engineering has justintroduced the innovative new Wilo-Stratos Pico high-efficiency smallcirculator pump into the Irish marketplace. The latestin the family of high-efficiencyA-rated small circulators, the Pico is right at the top of the class when it comes to energy efficiency costsavings with an averageelectricity consumption of just46.5 kWh for a typical home.

“According to standardEuropump Commitmentmeasuring procedures”, says Tony Cusack, ManagingDirector, Wilo Engineering inIreland, “when it comes toelectricity consumption, Picois more efficient than anyother A class pump on themarketplace, delivering anincredible 90% on energy

savings over standard pumpmodels.”

As you would expect froma Wilo product, the StratosPico offers every benefitexpected of a high-efficiencysmall circulator, includingreliable starting andmaximum convenience dueto its high starting torque andin-built de-blocking software.It is simple to set up, quick toinstall, and features a displaywith a consumption reading,along with a thermalinsulation shell as standard.

The new unit also features a clever power connection.Previously, installers had to connect the ends of thepower cables to the terminalbox. Now with the specialWilo Connector incorporatedwithin the Wilo-Stratos Pico,installers simply connect the

cable to the patented plugconnection and plug this intothe corresponding connectionon the pump

It is vital that the unit’ssetting is correct. In order toallow installers get this right,the Wilo-Stratos Pico isequipped with a large display,just like its big sister the Wilo-Stratos. This means thepump can be operated andread with ease from the front,and all the important settingparameters can be seenconveniently at a glance.

The large display is also an advantage for residentialcustomers as it allows themto read the current powerconsumption and totalelectricity consumption at any time – effectivelyproviding them with their own electricity meter.

Air purging is also simple –at just one press of a buttonthe Wilo-Stratos Picoactivates its automatic airpurging facility to ensuremaximum performance and minimum noise.

“But it is the incredible 90%

energy saving which reallysets the Pico apart from thecompetition”, says Cusack.“Obsolete, uncontrolledheating pumps are some ofthe worst culprits when itcomes to energy wastage soreplacing them with the newWilo-Stratos Pico savesenergy, saves money andhelps save the environment.”

According to Wilo, the TÜVSÜD (German TechnicalInspection Association South)calculated an average annualelectricity consumption ofonly 46.5 kWh for a typicalfamily house according to the standard EuropumpCommitment measuringprocedure. This makes theWilo-Stratos Pico the onlyhigh-efficiency pump whichhas had its high-efficiencyperformance certified by TÜVSÜD. The certificate can beseen at www.wilo.com/legal.

While many knew knew him well in the professional context, hisson John revealed other sides to Eoin which were quite revealingduring his address at the funeral Mass. Those present got a picture of Eoin the man, the husband, the father, the friend and yes, theengineer, and the extraordinary way engineering occupied his everythought. The fact that five of his seven children went into engineeringsays it all.

Eoin was a lovely, intelligent, persistent, meticulous, gentle, patient,sensitive, inquisitive, curious, idealistic, cultured, man.

Born in Dublin on the Ides of March in 1921, he often said that hewas “the same age as the State”. He went to school in ColáisteMhuire where he perfected his Irish and subsequently became alifelong advocate for the language.

He qualified in mechanical and electrical engineering from UCD in1943. It was in the middle of the second world war and the family hasa picture of Eoin and his classmates – all jackets, trousers and ties –outside what is now the Taoiseach’s office. Eoin often said that heand his friends doubted at the time whether any of them would seethe year 2000. However, he not only got to 2010, but used thatengineering degree nearly every day of the succeeding six and a half decades.

Eoin had many aspects to his life and personality, some of the keyone being the following.

EngineeringEngineering was not just his profession but an all-consumingpassion. After a brief stint in the UK following graduation, he returnedto Ireland to join the family firm of JA Kenny & Partners. Over theyears the firm was involved in huge numbers of projects throughoutthe country and Eoin would incorporate site visits into family holidaysat every opportunity.

All his children have memories of sitting in the car at BallinasloeRegional Hospital – en route to their summer holidays in Carraroe –waiting for him to finish a meeting. As his son John recalled, therewere no phones back then, or iPods or Nintendo DS’s, just sevenkids in the back of the car!

Over the years JA Kenny also did a great deal of work with Pfizers and other key multinationals and were very much part of the economic transformation of Ireland. Noel was particularly proudthat Kennys’ joint venture with Gasunie of the Netherlands won thecontract for the Cork-Dublin gas pipeline.

After retirement (so-called) he kept active with advising on smallerprojects – Enniscorthy Cathedral and the Swiss Embassy wereamong typical clients. He also got called on more and more as anexpert witness in legal cases, being called to give his opinion on

Eoin Ó Cionna (Eoin Kenny) remembered


OBITUARY

The death has taken place of Eoin Ó Cionna, one of the industry father-figures and aleading innovator in all matters relating to building services. He received many honours and accolades down through the years, serving both clients and the industry at large with distinction for nearly 60 years.

boiler explosions, fires, plumbingdisasters, typically in domestic cases, all of which he did with huge care anddue diligence.

He enjoyed enormously bringing both the full weight of his accumulatedknowledge, and the spare time that henow had, to bear on the case, and wouldresearch every theory and angle wellbeyond the strictly necessary and wellbeyond what he would bill for. His lastrecorded consultancy job was in August2008 … when he was 87!

PoliticsEoin was deeply interested in politics,which was part of his dedication to theIrish State. He met most of the majorhistorical figures such as de Valera andLemass, and was closely associatedwith Jack Lynch, Erskine Childers andGeorge Colley among others. His longinvolvement in Fianna Fáil was in MountStreet, as one of the organisers, sittingon committees, running and organisingthings. For his children, this meantstuffing envelopes at home on the diningroom table for Jack Lynch in the 1974campaign, or writing addresses by handin Mount Street onto envelopes for JackLynch or Erskine Childers. Indeed, Eoinwas part of the team who put Childerson a modified bus with tables and armchairs in it, as opposed to the thenpractice of sticking your head out of a car sun roof.

OrganiserIn 1971 he persuaded up to 10 people tojoin him in purchasing Mirror dinghiesfrom England, so that they all got adiscount. The family ended up buildingtwo, with most of the ground floor roomsbeing used for assembling the DIY craft.The smell of glue was everywhere –probably because he stored the resin in

the fridge on one occasion. But most ofhis children who could do so did join in… learning some DIY skills on that boatthat stayed with them for life. The Kennyfleet was augmented by two canoeswhich were built in the garage.

EnthusiastEoin was an avid model railwayenthusiast. As the electric train set gotbigger, it was fighting for space in theplayroom with the toys of the seven kids.So, he devised a platform from mildsteel and plywood which could be raisedand lowered from the playroom ceilingon industrial-strength hand wincheswhich were bolted to the wall. Thin butstrong cords ran up the wall, over to themiddle of the room, where the platformhad an enormous hole in it toaccommodate the play room light. Thiscontraption stayed in place for decades,and when as teenagers the children haddiscos in that room their friends wouldask about the winches on the wall. Itwas such an unusual spectacle that theyhad difficulty explaining it.

PeopleEoin was open and friendly, alwaysgiving those he met the benefit of thedoubt – sometimes to his disadvantage.But that trust in people meant that in all his years, no one can recall that he made a single enemy, or even that he fell out acrimoniously with anyone,either socially or professionally.

MusicAn accomplished singer, he couldenthrall an audience with his renditionsof ballads and traditional songs.

FamilyDespite his many interests Eoin stillfound time to be tremendous family man.A devoted husband and father, he wasequally involved with all his grandchildren.Right up to his death he epitomized thetrue spirit of the family man – while hisdeath is a great loss to all, he has left arich legacy which will see his memoryand influence live on in futuregenerations, both personally andprofessionally. �


A kinsman pays personal tributeEoin Kenny, O’Cionna, qualified in mechanical and electrical engineering at UCD in 1944, just as the great war ended. Hisfather’s consulting practice was the leading Irish one at the time, though no doubt slight in such lean times. Other practiceswere Tierney Matthews and Delap & Waller, the latter whom I joined briefly before moving to Varming in 1947.

Eoin rapidly expanded his practice, particularly in the post-war hospital programme, and was active in the newly-formedAssociation of Consulting Engineering in Ireland. In fact, the early AECI meetings were held in the offices of JA Kenny &Partners, and Eoin was President in 1966 and 1967.

Technical excellence and exuberant energy ensured his role in the complex, not always fluent, teamwork of buildingdesign. Pipes and wires were “a bore, and the bigger the pipe …”. Inexorably however, modern architecture, building useand performance, demanded multiple and extensive services. Eoin would have been foremost in enabling architecture.

He was a fine man, a good friend, and in my case, a kinsman.Sean Mulcahy

Early areas of expertise included boiler FD and ID fans, variousfans for the meat processing industry, grain aeration, and spraydryer fans. As its reputation grew, so too did the areas ofapplication, dehumidification of spray dryer inlet air being a case in point. To that end Turbo Air has a trading partnership with Munters and recent client installations include blue-chipindustry leaders, Kerry Ingredients (Malaysia and Listowel) being among them.

This is the perfect relationship as both Turbo Air and Munters specialise in controlling humidity and creating optimal conditions for both products and people. Working together they provide sustainable turnkey

solutions delivering consistent quality in production and storage,as well as comfortable indoor climates for people.

Factory-assembled skids can include dehumidification,humidification, heating, cooling and high-grade filtration. Inaddition, systems are factory-wired to a dedicated control system that can be linked with any on-site BMS system. This is critical in pharmaceutical and medical-device facilities where humidity control is all-important.

The same exacting design, manufacture and installationstandards are applied to dust collection applications (DonaldsonTorit). Here again Turbo Air provides the highest-quality solutionsincorporating all necessary accessories – the client merely has to

connect the mains power. All are equipped (but not limited to)explosion-protection systems, dust containment facilities, controlspackage, HEPA after filtration, ATEX fan set and discharge, anddischarge attenuation.

To further ensure an all-embracing service, Turbo Air also offers a fan repair and balancing service, and is the only Irishmanufacturer of industrial-rated centrifugal and axial fans.

In celebrating nearly 40 years in business, Turbo Air is firmlyfocused on the future. It has reinforced its already-establishedstrengths and looks forward to working closely with its keysuppliers – especially Munters – to consolidate and grow its business. �

Virgin HCFC bankick-starts year


While green-field construction projects arefew and far between at present, the banon the use of virgin HCFCs for

maintenance and servicing – which came into forceon 1 January 2010 – has created a flurry of activityin the retrofit sector. A combination of ageingequipment, plus a desire by many to upgrade tomore energy-efficient systems, has created a surgeof interest in the ac and refrigeration sector.Anticipating this scenario, all the leadingmanufacturers already have the product armoury tomeet this demand, while installers are equally well-prepared for the change-over. Legislative changesof this magnitude very often bring associatedproblems but, in the case of the virgin-HCFC ban, it really has opened a whole vista of marketopportunities to be exploited.

Sanyo Air Conditionershas developed a newapproach that enables rapidconversion of existing R22-based air conditioningsystems to new, high-efficiency, R410A systems atdramatically-reduced cost.

The company’s R22Renewal system usesexisting refrigerant pipeworkto speed up installation andcut replacement costs byaround 30 per cent. It alsodelivers significant ongoingsavings in running costs forend users, due to theincreased energy efficiency ofR410A equipment. This hasCOPs of up to 4.5 comparedwith 2.5 and below for olderR22 systems.

Sanyo Renewal can beused with both existing Sanyosystems and virtually all typesof R22 systems from otherleading manufacturers. Onmost installations, existingwiring can also be used. Anyflare connections are replacedto upgrade the system toaccommodate the higherworking pressures of R410A.

With PACi and VRF

systems, installers carry out asimple oil test to establishthat the system has not beensubject to a burn-out.Pipework is also checked toensure it is not damaged andthat wall thicknesses arewithin acceptable guidelines.For VRF systems, checks arealso carried out on pipelengths and branch networksto ensure they meet currentdesign criteria.

Existing indoor and outdoorunits are then replaced withcurrent products fromSanyo’s range. In the case ofsplit systems, the outdoor unitis selected from Sanyo’sClassic, Standard or Eliteranges, depending on the

level of efficiency required.For VRF systems, any of thecompany’s range of two-pipeor three-pipe options can beapplied.

“The arrival of R22Renewal is great news forboth contractors and endusers,” says Barry Hennessy,

Sanyo’s Sales & MarketingManager. “There is a hugeamount of R22-basedequipment out there. With the ban on use of virgin R22for service top-up now inforce since 1 January 2010,people with R22 systems areseriously exposed.

“R22 Renewal enablesR22 plant to be quicklyreplaced with modern, high-efficiency air conditioning,saving around a third or moreon replacement costs, anddelivering significant ongoingsavings in energy costs. It isa win-win for all concerned,including the environment.”

For installers, no specialtraining is required to carryout Renewal conversions.Refrigerant is reclaimed in thenormal way, while on VRFinstallations the suitability ofpipework is confirmed by aSanyo distributor or themanufacturer.

The Renewal approach canbe used with all existing

equipment that meetsSanyo’s pipework criteria. It can also be applied toexisting R407C systems.

Sanyo has introduced R22 Renewal across Europe to coincide with theimplementation of the EU-wide phase-out in the use of virgin R22 for top up. InIreland alone, there areestimated to be between15,000 to 20,000 airconditioning systems still running on R22.

Barry Hennessy says: “R22 is still a mainstay formuch of the installed base ofair conditioning. The ban hasbeen a long time coming, butmany end-users have so farfailed to grasp the nettle. Thetiming, coinciding with theeconomic situation, hasn’thelped.

“However, it is highly risky not to take action, in thehope of obtaining sufficientreclaimed R22 to keepsystems running. The truth isthat there simply won’t besufficient to go round, and thecost – where it is available –is likely to rise dramatically.”

He added: “Renewal offersa practical, cost-effectivesolution that is quick andeffectively future-proofs end-users against uncertainty.With energy costs predictedto rise year-on-year for theforeseeable future, the costsof conversion should pay forthemselves many times over.Renewal can be also used toreplace R407C systems,providing end users andinstallers with a further option.”

Now that it is illegal to use virgin HCFC’s for themaintenance and servicing of refrigeration and airconditioning, specifiers,contractors and clients alikeare looking to manufacturersto deliver alternativesolutions. Apart from beingregulatory compliant, thesesolutions have to be cost-effective to install and energy-efficient when operational.

It is against this backgroundthat Mitsubishi Electricdeveloped the Replace AuditTool. This unique softwarepackage makes comparingold with new very easy –simply by inputting somebasic information on theexisting system and selecting new equipment from theMitsubishi Electric range, a comparison can begenerated which highlights

reductions in CO2 emissionsand running costs.

The Replace Audit Toolalso highlights supplementaryinformation around the issueof R22 phase-out, especiallyin relation to Governmentincentives which apply to new ac equipment. Olderequipment can be veryinefficient when comparedwith modern alternatives,whereas innovations such as new refrigerants andinverters have seen energyuse from air conditioningsystems dramatically reducein the last 10 years.

Replace TechnologyThe M Series and Mr Slimpower inverter/zubadaninverter ranges incorporateReplace Technology to allowthe upgrading of systemsusing existing pipework,without the need to apply anyspecial cleaning machines.

Sizes 25 to 71 utilise theMitsubishi Electric patentedHard Alkyl Benzene (HAB)oil, a unique oil that is moretolerant of contamination. By combining this oil withdevelopments in oil separatortechnology, it is possible forthese models to use existing

pipework without any specialoperations.

Sizes 100 to 250 continue touse the more familiar Ester oilsthat are sensitive to chemicalcontamination. To allow thesemodels use existingpipework, a unique ReplaceFilter containing activatedcharcoal has been included inthe refrigerant circuit.

During commissioning, thesystem is operated in ReplaceMode, this operation removingall the chlorine contaminationfrom the existing pipework,allowing trouble-free operation.

Mitsubishi Electric alsoruns regular training seminarsat its Dublin headquarters tofamiliarise installers withReplace Technology.

Completing the “cradle-to-grave” service provided,Mitsubishi Electric also offers a logistics package inrelation to refrigerantdisposal. In conjunction with an accredited specialist,it provides a comprehensivedisposal facility which is fullycertified and guaranteesregulatory compliance.

16The Ecodan range of air source heat pump systems have beendeveloped by Mitsubishi Electric specifically to suit Irish weatherconditions.

Air to water heat pumps (Ecodan)One of the latest additions to the Mitsubishi Electric rangeis the new Ecodan air source heat pump. Many haveheard of ground source heat pumps and the highefficiency levels they can offer but air source heat pumps,such as Ecodan, also offer significantly-higher levels ofefficiency when compared to traditional heating methods.Additionally, they are much easier to install and so aremore suitable for a wide variety of building types, fromapartments to detached houses.

The Ecodan air source heat pump system consists of anexternal packaged system with a built-in water exchangerwhich is plumbed in like a conventional oil/gas boiler unit.It harvests renewable, low-grade energy from the outdoorair and upgrades this into useful heat to supply a homewith hot water and heating. For every 1kW of electricityfed into Ecodan, you will get at least 3kW of heatingenergy. It can work efficiently all year round, even if theoutdoor temperature should drop to -15ºC.

Installation costs vary from property to property but, asa guide, costs are similar to that of a conventional gas boiler.

From data provided by BRE testing (the UK's leadingcentre for independent advice for the built environment), and from case study analysis, running costs can bereduced over a conventional gas boiler by approximately35%, using standard tariff electricity.

Full details on the Recycle Audit Tool, Ecodan and otherinnovative products are available from Mitsubishi Electric’sdedicated Irish office.

Daikin Europe NV hasintroduced VRV®III-Q as a cost-effective upgrade from systems operating onthe recently-banned R22refrigerant to a state-of-the-art R410A system. Due to its high ozone-depletingpotential, a total ban onrecycled R22 will come into force in 2015. DaikinVRV®III-Q provides a cost-effective upgrade path from

existing R22 VRV® systemsto a new R410A VRV® systemby minimising downtime andinvestment.

There are many reasonsfor companies to considerupgrading now. First andforemost, even before thetotal ban on the use of R22 in2015, the use of virgin R22has been banned in theEuropean Union fromJanuary 2010 onwards.

Therefore supplies of R22 willbecome scarcer and moreexpensive, a trend that hasalready begun. Withoutreclaimed R22 available,certain maintenance will nolonger be possible, with therisk of a longer downtime.

Thanks to the significanttechnological developmentsof inverter-based heat pumptechnology and the moreefficient refrigerant, majorimprovements in operatingcost can be expected withnew systems. Not only theincreased energy efficiencyand thus lower CO2emissions, but also the zeroozone depletion potential ofR410A makes the upgrade ofan R22 system less harmfulfor the environment.

Users of R22 VRV®

systems have a number ofoptions, ranging from doingnothing to installing acompletely new system. With the former option, inaddition to the environmentalburden, there is a risk ofsignificant downtime as wellas costs if problems arise. On the other hand, the fullreplacement option requires a high investment and isdifficult to justify, especiallywhen the existing R22equipment is relatively newand operating satisfactorily.

Daikin VRV®III-Q makes it easy for customers toupgrade now. The VRV®III-Qsolution allows existing R22

piping – and in some caseseven the indoor units andcontrollers – to be retainedand replaces only the outdoorunits and BS-boxes (in caseof heat recovery installations).This allows a phasedreplacement, a spreading ofinvestment costs and minimalbusiness disruption.

The VRV®III-Q has beenspecifically designed tooperate on lower pressuressuitable for existing R22piping while maintaining ahigh energy efficiency level.

Oil and contaminants inexisting piping can causeequipment malfunctions, andhence in the past the copperpiping was always replacedwhen a system with adifferent refrigerant wasinstalled. The VRV®III-Q, witha newly-developed cleaningfeature, eliminates this risk.During automatic charging,contaminants are filtered out,guaranteeing a reliable andfast VRV®III-Q installationwith existing piping.

VRV®III-Q is available inconfigurations of 5-30 HP, inheat pump and heat recoverymodels. All existing R22 andR407C VRV® installations canbe replaced. In addition toboosting efficiency, thecapacity of the system can beincreased without changingthe copper refrigerant piping,allowing adaptation of thesystem to increased coolingand heating loads.

The product launch forVRV®III-Q is foreseen for early 2010. For moreinformation on Daikin Europe’sVRV® solutions for new andexisting constructions, visitwww.daikin.ie or [email protected]

GT Phelan has noticed asteady increase in the numberof R22 replacement projectsduring the last two years. Thismarket is projected to grow asthe full effects of the HCFCban comes into play anddirectors Rodney, Derek and Kevin Phelan – who thisyear celebrate the 40thanniversary of the founding of the company – aim tocapitalise on this potential.

GT Phelan is well placed toserve this growing market asit has the experience of a widevariety of retrofit applications.“All Toshiba equipment from

the light commercial range issuitable as replacementtechnology”, say Derek. “Theexisting pipework can be re-used, providing that the wallthickness of the old pipeworkcan withstand the higherpressures associated with R410a.

“However, if the R22system has suffered a burn-out, it is recommended thatthe pipework is completelyreplaced. Where this is notpossible, the pipework must be flushed using anenvironmentally-friendlyflushing agent which must

then be completely removedprior to re-commissioning.”

All of the old R22equipment uses larger pipesizes than are required forR410a systems. This posesno problems for Toshiba asthe latest generation R410aequipment is designed to deal with this issue.

Having completed manyretrofit changeovers during

the past two years, theperformance of each newsystem is monitored and no detectable losses areobserved. “Air offtemperatures are extremelygood from any retrofits wehave been involved in” saysDerek, “and customers areextremely happy with thereduced running costs fromtheir A-rated equipment. They also have the addedbonus of a three-yearwarranty covering parts, with a labour allowance.”

Most fixed-speed R22equipment is energy rated “G” or worse, so customersbenefit greatly from thereduced operating costs andCO2 emissions. Toshibainverter-controlled heatpumps also offer enhancedcontrol, resulting in fewercomplaints of temperaturefluctuations from end-users.

Toshiba also look forward to introducing replacementtechnology for the VRF andresidential range, allowing GT Phelan to cater for anyretrofit application presented.

Hitachi Europe hasenhanced its centrifugalrange of air conditioners byintroducing the DC inverter-driven RASC 3hp, 5hp and10hp units, which are claimedto be capable of reducingannual electricity usage by up to 25% in business anddomestic settings.

The new products are also easier to fit and offergreater flexibility in terms of installation. They aredesigned for indoorinstallation, where outsidespace is not available.

Fergus Daly, SalesManager, Hitachi Ireland, isvery excited about the newunits. He said: “The DC-inverter compressors on theRASC 3hp, 5hp and 10hpdramatically reduce electricityconsumption, providingaverage savings in the regionof 25% based on typical Irishoperating conditions when

compared to the previousfixed-speed models.

“High efficiency DC inverter controls also allow forincreased customer comfortas the set temperature isreached quickly andmaintained more accurately”.

According to Hitachi thenew units are easier to install– the 3hp and 5hp models are15% lighter due to a reductionin height, and the introductionof DC inverter horizontalscroll compressors. The 10hpmodel features increasedpiping length of 30m to 50m.

All the models featureflexible inlet and outlet airflowconfigurations, allowing eachinstallation to be tailored toindividual customer needs.The new models can bepartnered with the full rangeof Hitachi System Free indoorunits and controls with single,twin, triple and quadconfigurations possible.

The world renowned andhighly reliable Hitachi DCinverter scroll compressors on the new products allow forimproved performance andreduced operating costs.These compressors arehorizontal in the 3hp and 5hp models, reducing theheight of the units.

Fergus Daly concludes:“We’re delighted with ourimproved centrifugal range of outdoor units. The newmodels are specificallyengineered to provide morebenefits to our customers,enabling a simpler, moreflexible installation, along withgreater energy savings.”

These new units are theperfect addition to the Hitachiportfolio, being introduced asthey are in this, the 100thanniversary year of thefounding of the company.Over the last century Hitachi has remained committed to developing advancedtechnology solutions, all the time looking to the futureand investing in extensiveresearch activities to ensure

that Hitachi continues to leadthe field.

Today’s Hitachi range isone of the most extensive on the market with productsand equipment suitable for all manner of applications,from domestic through to the modern multi-storey office environment.

Specifiers, installers andusers alike can rest assuredthat performance and costefficiency are not the onlyparameters by which Hitachiproducts can be judged.Ecological thinking stemsfrom the very first stages of new product design andcontinues throughoutproduction and on toinstallation procedures,equipment and operation,with priority being given to the use of environmentally-friendly refrigerants such asR407c and R410a. The newly-expanded centrifugal rangeepitomizes this philosophy.

Smart metering behaviour trials get underway

The Commission forEnergy Regulation (CER) is overseeing the National

Smart Metering Plan and 6,500meters have been installed inclusters around the country.Sustainable Energy Ireland ischairing the customer behaviourwork-stream.

Various aspects of thetechnology are being tested, aswell as the reactions of consumersto different types of billing andaccount information provided bythe suppliers taking part.

Some of the participants will beable to get feed-back on theirconsumption online, and otherswill be able to get real-timeconsumption information via an in-home display (IHD). The IHD is often confused with the smartmeter but it is an add-on whichcommunicates with the smartmeter in the metering cabinet.

Time-of-use tariffs will also betrialled. At present most customerspay a flat price or tariff for theelectricity they consume,regardless of the time of day it is generated and consumed. This flat tariff does not reflect the actualcost of the unit of electricity at amoment in time; rather it is aforecasted average cost.

Time-of-use tariffs reflect moreaccurately the cost of generatingelectricity at different times of theday and night and, if this variableprice is passed on to theconsumer, they have the incentiveto modify their electricity use toreduce their bills. Pre-payment,which can help consumers budgettheir electricity expense, will alsobe incorporated into the trials.

Further initiatives will be trialled which will incentivise the consumer to not only shiftconsumption from peak to off-peaktimes, but to also reduce theiroverall use of electricity. Bord GáisNetworks will also be trialling gasmetering technology in nearly2,000 locations.

It is hardly surprising to note that 2009has been one of the most difficult yearsfor mechanical and electrical specialistcontractors, given that Ireland is now inthe grip of an economic depression notseen since the 1930s. While majorproblems face the economy at large,there is no denying that the constructionindustry – an industry which mechanicaland electrical sub-contractors are hugelyreliant on – is suffering more than most.

First we witnessed the collapse of theprivate residential and commercial sectorsand, more recently, the government hascut back the Public Capital Programmefrom approximately e10 billion per annumto a projected e6.5 billion for 2010.

Within this setting, competition for projects has been very intense and manyindependent indices suggest a fall intender prices of up to 30%. We can anticipate a further reduction in work across all sectors of the construction

industry and M&E contractors are struggling to survive

with the curtailment of cash-flow and the difficulty in collecting monies owed.Additionally, securing new projects atsustainable prices has become next-to-impossible in the current marketconditions.

Dealing with client insolvencyThe full effects of the current recessionare now evident in our sector and inorder to protect your own business, it isimportant to be alert to possible warningsigns of impending insolvencies of yourcontracting counter-parts, and to takewhatever actions you possibly can toprotect yourself.

The news that a client for a project hasgone bust and that the main contractor isnow refusing to pay subcontractorsbecause it has not been paid itself is justanother day at the office for the majorityof sub-contractors. In the event of clientinsolvency, main contractors operate thispractise under a “pay-when-paid” regimewhich exists in many forms of sub-contract. In the event that the partieshave not agreed a “pay-when-paid”clause, then the main contractor isobliged to pay up … otherwise he is inbreach of contract.

A proportion of a sub-contractor’s losswould inevitably be retention moniesheld. These sums have been earned bysub-contractors and are simply retainedto be used if necessary, for specificpurposes, or to be paid to the sub-contractor at specific times. Manystandard contracts have a provision for retention funds to be held by theemployer, in trust for the main contractor,in a separate bank account.

However, this is not automatic andrequires the specific agreement of both

the employer and the main contractor– in reality it is seldom used. Manysub-contractors would argue that thefacility to hold retention in a separatetrust fund should become a standardcontract condition in all forms ofconstruction contract, for maincontractors and sub-contractors alike.

Chasing paymentWhen money is scarce, non-paymentand late payment become widespread.Actions to recover a debt may bethwarted by turning the debt into adispute, however spurious. Asinequitable as it may seem, sub-contractors should devote time andeffort to the task of getting paid andinstall procedures to monitor receipt of payments.

To ensure payment on time it isabsolutely imperative that you are fullyaware of the payment provisions inyour contract. It is essential to submitpayment applications by the requireddates and, under certain forms of sub-contract, submitting an application at aspecified time is a condition precedentto getting paid.

Design changes generate variationsthat require valuing and often the costsneed to be substantiated by invoicesand documents. This takes time andnegotiation and is often the breedingground for late payment and disputes.It cannot be stressed often enoughhow important it is for sub-contractorsto adhere to the notification andreporting requirements of theircontract. You must maintain detailedrecords on an ongoing basis to supportand substantiate variation and delayclaims so that you are in a position to

make ongoing applications forpayment. While many may view it as a paper-wasting exercise, it will oftenbe the difference between getting paid on time or not at all.

If the final date for payment passesand there has been no response at all,immediate action is required. At thispoint, the difference between a debtand a dispute is important. To establisha debt, a sum of money must be owedand due. There must be no knowndefence and no dispute raised by theother party. Debt is generally a case of“cannot pay”. In any case, you shouldbe focussed on moving the process onas quickly as possible in order toobtain payment or alternatively, have adispute crystallised so that the disputeresolution mechanisms under thecontract can be invoked.

If neither payment nor a validwithholding payment notice has beenissued, the sub-contractor maysuspend the performance of the works,provided he gives written notice inaccordance with the provisions of his

sub-contract. This is a valuable remedyto a sub-contractor, but it is essential toserve the correct notice required by theterms of the sub-contract. Work mustcontinue if payment is made during thenotice period.

Parallel to the suspension notice, a notice may be given to inform theother party that interest will be chargedon outstanding payments, either inaccordance with the terms of thecontract (if such a clause exists), or under the EU Late Payments inCommercial Transactions Regulations2002. This EU Directive came intoforce in Ireland in August 2002 but, ifwe look at the UK experience whichhas had similar legislation since 1998,only 2% of businesses will attempt toclaim interest under the legislation.

I would advise that charging interestshould only really be used as apersuasion tool. Sub-contractors could divide their clients into twodifferent categories – “good” and“average/poor” and apply appropriatepersuasion techniques to eachcategory. The “good” category clientsshould generally not be chargedinterest on the basis that it mayalienate a client who normally paystheir bills on time. Interest could,however, be applied with clients whofall into the “average/poor” category.

If the above procedures areimplemented, the other party shouldreceive three letters on their desk – arequest for payment, the suspensionnotice and a notice that interest will be charged. This approach should focus their attention and promoteremedial action.

New projects – how secure is your client?Sub-contractors commencing work on new projects in the current climateshould be very cautious as it is nowmore important than ever to carry outthe necessary due diligence on thepotential client. Firstly, the sub-contractor should always establish whothe employer and the main contractorare, and credit ratings can be checkedusing a credit data provider. A view canthen be formed regarding the financialrisk involved in sub-contracting on thatparticular project. If the credit ratingreport you receive is rather complex,advice should be sought from anaccountant.

Trade references can also bechecked, but you should ensure thatyou are happy with the supplierselected as a referee. Anotherinvaluable tool for identifying badplayers is networking. You can makecontact with other contractors on site,or other sub-contractors in the industrywho have previously worked for theclient/main contractor. You can alsocheck if financial accounts areavailable on the CRO or SoloCheckwebsites and be concerned if they arelate in publishing them.

Terms and conditions of contractSub-contractors should always ensurethat they obtain a copy of the relevant

sub-contract terms and conditions,together with all other contractdocuments. In addition to maincontractor bespoke forms of sub-contract, there are various standardforms available as follows:

Private Sector Works– RIAI Nominated Form of Sub-

Contract 5th Edition 1989;– CIF Specialist Contract (Domestic)

1st Edition 1999.

Public Sector Works– CIF Domestic Form (Agreement and

Conditions of Sub-Contract) 1stEdition May 2008;

– CIF Named and Novated Form(Agreement and Conditions of Sub-Contract) 1st Edition February 2008.

With private-sector construction workdeclining, more and more projects aretendered under the GCCC Forms, oftenreferred to as the new governmentcontracts. To date, mechanical andelectrical specialist contractors havebeen employed as domestic sub-contractors so the appropriate form ofsub-contract is the CIF Domestic Formpublished in May 2008.

Sub-contractors should be mindful of any amendments incorporated into a standard form by a main contractor.In some instances the main contractorwill provide you with a list ofamendments which will apply to thestandard form and this presents the

sub-contractor with the unenviable andtime-consuming task of collating thedocuments to verify the impact of theamendments. More often than not, theproposed amendments will not favourthe sub-contractor and can includeextensions to the payment period,more onerous insurance clauses, and “pay-when-paid” provisions.

Once you are presented with theform of sub-contract for any particularproject, you should firstly establish if it is a standard form and, if not, thepotential impact of any amendments.Then you should familiarise yourselfwith the payment clauses, payingparticular attention to when the firstpayment becomes due, the paymentintervals (generally monthly), and thefinal date for payment. This is criticalas any subsequent actions, such assuspension of work due to non-payment, will only be valid if thecorrect dates are used. You shouldalso establish the retention to be heldand pay attention to the provisions forits release.

During the course of the contract, allpaperwork and records should be keptup to date and attention needs to begiven to ensure that the correctrecords are being produced todefinitively substantiate variations,disruption and delay claims. Sub-contractors, now more than ever,need to be absolutely meticulousabout serving notices on time, andcorrectly, according to the proceduresin the contract.

If sub-contractors take the time toheed some of the advice contained inthis article, then they will minimise therisk of non-payment, insofar as ispossible. If they enter into contractswithout taking heed of the terms andconditions of the contract, and of thefinancial standing of their client, thenthey are doing themselves a disserviceand putting their business at risk. �

IntroductionAs of September 2009, the Fourth Editionof the National Wiring Rules, ET101:2008,came into effect and is now the mandatorystandard applicable to electrical circuitssupplied at nominal voltages up to, andincluding, 1000V ac or 1500V dc indomestic, commercial and industrialinstallations. The rationale for theintroduction of the fourth edition is theprogression at international level of theharmonisation of wiring standards.

Harmonisation encompassesdocumentation restructuring, includingthe introduction of new developments oftypes of equipment, technical changes,and the inclusion of new developments inwork and building practices.

Over the next three issues of bs newsthis series of articles will outline thespecifics included in this enhancedstandard. Details concerning the renewedimpetus from a legislative perspectiveassociated with this publication will alsoserve to contextualise the significance ofthe standard for consulting engineers –both electrical and mechanical – as wellas for the electrical contracting sector.

This month’s article explains the role ofthe Electro Technical Council of Ireland(ETCI) in the context of the NationalWiring Rules, reaffirms the scope of theRules, and explains the reasoning behindthe introduction of the Fourth Edition.

Electrco Technical Council ofIreland (ETCI)The ETCI is a voluntary bodyrepresentative of all aspects of electro-technology in the Republic of Ireland. It isthe national body responsible for theharmonisation of standards in the electro-technical field, as well as prioritising thepromotion of electrical safety.

In conjunction with the NationalStandards Authority of Ireland (NSAI),ETCI defines and harmonises thestandards relating to the practicalimplementation of safety measures forelectrical installations as detailed in “ET 101:2008 – the National Rules forElectrical Installations”. The ETCI hasalso published many other documentsto provide clarification for the industry,including a Guide to the BasicPrinciples of Electrical Safety (ET213:2007) and also Good PracticeGuide on the Management of ElectricalSafety at Work. Figure 1 shows ETCIin context with all relevant national andinternational standards bodies.

National Wiring Rules The National Wiring Rules apply toelectrical circuits supplied at nominalvoltages up to and including 1000V ac or1500V dc which form part of installationsin residential, commercial, industrial orpublic premises, or of installationscontained in prefabricated buildings,caravans and halting sites, as well asinstallations for specialised purposes,such as those in agricultural andhorticultural holdings.

These rules do not apply to electricalequipment for traction in automobiles oraircraft or on board ships, to installationsin mines and quarries, systems fordistribution of electrical energy to thepublic, power generation or transmissionfor such systems, radio interferencesuppression equipment or lightningprotection of buildings.

Justification of the FourthEdition (ET101:2008)Since the publication of the Third Edition,the National Rules have maintained

Wiring rules – fourthedition now mandatorystandard

alignment with technical and marketadvances through a number ofamendments (ET101:2000/A1:2000,ET101:2004/A2:2005). However, therehave been changes internationally withmajor restructuring of the InternationalWiring Rules and, as such, thesechanges warrant the publication of aFourth Edition so that internationalharmonising of wiring rules in IEC andCENELEC can be implemented.

As members of CENELEC, it isincumbent on ETCI to considermodifications or clarifications made atEuropean level and to either accept or seek the retention of specialrequirements or “Special NationalConditions (SNC)” if technical aspectspresented by CENELEC contradict thenational position.

Summary of major changes The major changes introduced in theFourth Edition include changes or newmaterial in the following areas:

Wiring systemsChanges are contained within Chapters51 and 52. In Chapter 51, theidentification and marking of cables hasfinally been completed. Chapter 52provides detail pertaining to theselection and erection of wiring systems– originally introduced in the secondamendment – and specifically in relationto external influences which includecorrosive substances and impact;

Switchgear and accessoriesThe Department of the Environment(DOE) has specified mounting heights(socket outlets, light switches, controldevices and distribution boards) ascontained in Technical GuidanceDocument M of the BuildingRegulations. Isolation of inaccessiblesocket outlets (554.3.5) address therequirement of isolation where anappliance needs to be switched-off in the case of malfunction;

Overcurrent protectionNew requirements with regard toharmonics, meter tails, spurs and surge protection are provided. – Cognisance of the current-carrying

capacity is required in situations whereharmonic currents are prevalent;

– The accommodation of the mainprotective device (of domestic orsimilar installations) within the ESB cabinet is provided;

Overvoltage protectionDetail pertaining to the provision ofovervoltage protection, specifically with regard to surge protection;

IsolationIsolation of premises in an emergencyhas been considerably enhanced toinclude detail on:– Premises having multiple supplies– Commercial premises– Apartment blocks– Switch rooms (electrical and building

requirements)

– Devices suitable for instigating isolation;

Residual current devicesA major change coming about by theintroduction of the Fourth Edition is therequirement for a sign at the location forthe installation distribution unit to testthe RCD on a monthly basis. Clarificationon the employment of RCDs in thecontext of water heating as well as for agricultural situations, temporaryinstallations and exhibitions is provided;

Special llocations/situationsNew rules apply in relation to a numberof “special locations” (including detail on PV installations (712), as well asclarification on special locations includedin the Third Edition is provided such asfor bathrooms (701) where detail relatingto the application of zones is clarified;

Verification and testingPre-connection testsThe insulation resistance valuesapplicable to the tests on final distributioncircuits have been increased. Also, a test originally introduced in the 3rdamendment, testing for erroneousconnections, has been re-emphasised;

Post connection tests:The values associated with testsconcerning the fault-loop impedance of final circuits have been de-rated to be cognisant of the thermal effect ofincreased current levels in cables under fault conditions;

Periodic inspection reporting and certificationThe above aspects detailed within theNational Wiring Rules have undergonesignificant revision and consideration to be inclusive of the increasedrequirements as outlined in the CriteriaDocument as specified by CER. �

The views expressed in this documentrepresent a personal opinion and should notin any way be construed as a definitiveinterpretation of ET101:2008 or indeed ETCIitself. This is not a legal interpretation. In theevent of a specific legal question, the readershould consult a practicing solicitor or amember of the Incorporated Law Society.

back issuesHappy birthday PatCongratulations to Pat Kelleherin Cork who celebrated a veryspecial birthday recently. I knowyou wanted to keep it low-key,Pat, but I could not let it passwithout a small mention.

How others see usWhat a pity we keep shootingourselves in the foot in the eyes of the rest of the world.With the vast bulk of buildingservices-related equipmentimported, I keep coming acrossforeign nationals from leadingmanufacturers who simplycannot comprehend how we price projects.

Stay in touchWith so many unfortunatelyhaving lost their jobs in recentmonths, remember to keep intouch with former colleaguesand business partners. It will come ‘round but, in themeantime, keep them in the loop.

Supermarketfridges ‘food’for thoughtA damning report by theEnvironmental Investigation Agency(EIA) in the UK – its second intosupermarket refrigeration – claims thatchemicals released by supermarketfridges account for 30% of their directemissions of greenhouses gases, withonly 0.5% of stores fitted with greenerequipment.

An EIA spokesperson concludedthat the environmental impact ofsupermarket refrigeration is a major,but little understood, issue and “a hellof a lot bigger than free plastic bags.”

The survey which led to the report,called Chilling Facts, did not includeIreland but industry sources suggestthat the figures for here are somewhatsimilar.

While an undesirable situationenvironmentally, it nonetheless pointsto an as-yet-untapped businessopportunity that equipment suppliersand contractors should seek to exploit.

Mad cap ideas or viable solutions?Following the failure of the Copenhagen climate talks toset meaningful CO2 targets, experts from around the worldare to meet in California next month to examine so-calledgeo-engineering solutions.

Some of the concepts proposed for discussion are:

Stratospheric aerosols– spraying sulphurcompounds into thehigh atmosphere toreflect sunlight;

Ocean fetiliistion –dumping iron into thesea to boost planktongrowth, which in turn

would soak up carbon dioxide from the atmosphere;

Space mirrors – most likely to be trillions of small mirrorsorbiting the earth (rather than one massive structure) toblock/reflect the sun’s rays;

Cloud whitening – fleets of sailing ships strung across theocean, spraying seawater into the sky to evaporate. Thiswould leave behind shiny salt crystals to brighten clouds,which would in turn reflect sunlight.

These proposals might seem far-fetched today but myguess is that younger readers of bs news will live to see avariation of some of these ideas adopted in the future.

As for the 10, 10, 10 conundrum! Did you know that a 10% drop in water vapour, 10 miles up in thestratosphere, has had a significant effect on global warming over the last 10 years– hence the 10, 10, 10 conundrum.

For all the talk of global warming, scientists –no matter where they stand on the greatenvironmental debate – agree there hasbeen a slowdown in the temperature riserate since the year 2000. Up to now noone could understand why but a newstudy suggests that it is linked to areduction in the amount of watervapour in the upper atmosphere.

Ironically, it is possible that this watervapour decrease was caused by awarming world so, more warming wouldsee further falls in water vapour and aconsequent reduction in global warming.

Confused? … I know I am. The more I try andkeep abreast of the latest research findings the moreI realise just how little the so-called experts understand.
