Industry finally pushingits own buttons!

While there is still a great deal of work to be done,developments over the last 12 months emphaticallydemonstrate that the building services sector is

determined to take ownership of its own destiny. Many were sceptical that the emergence of a handful of new

industry representative bodies earlier this year was but a fad, aknee-jerk reaction to the unprecedented difficulties facing theindustry. Thankfully, they have been proved wrong.

Throughout 2011 the Association of Plumbing & HeatingContractors of Ireland (APHCI), the Heat Pump Association(HPA), the Irish Ventilation Industry Association (IVIA) and theNational Insulation Association of Ireland (NIA) have maturedfrom fledgling newcomers into the authoritative voices of theindustry sectors served.

Individually, they have all engaged in lobbying for theirmembers’ interests at the highest level. This has includedGovernment Departments, statutory bodies, industryregulators, and inter-association activity.

As it happens, this intense activity coincided with an equally-energetic campaign by longer-established associations such as the Chartered Institution of Building Services Engineers(CIBSE), the Oil Firing Technical Association (OFTEC) and theInstitute of Refrigeration Ireland (IRI).

bs news has played a very active role in supporting the aimsand objectives of all the aforementioned, and has participatedin many of their activities. As a consequence, we recentlyfacilitated the inaugural Building Services Federation meeting(see page 2).

Bring on 2012 … it is not going to be easy but buildingservices will be united in meeting the challenge. �

Hevac supports DIT students Aa part of an initiative to attract more young people into the industry – and especially on to DITconstruction-related courses – Hevac has collaborated with DIT over the last six months to supportfive students from Michael Flaherty’s 3rd year Building Services Class (DT026/3).

The initiative was spearheaded by David Doherty of Hevac who made a presentation to the classof 23 students on his experiences since leaving DIT, and discussed with them the various avenuesopen to them within the industry. Subsequent to the presentation five students joined a specially-devised in-house Hevac mentoring programme covering the subjects they were majoring in. Theseincluded condensing boilers, under-floor heating, biomass boilers, district heating and heat pumps.

These students then visited Hevac’s headquarters on the Naas Road in Dublin and received ademonstration of a range of products from the various industry sectors featured in Hevac’s newly-completed product showroom. The day concluded with a breakout session with in-house designengineers demonstrating the various design disciplines related to the students’ sample projects.

Conversations covered installation procedures, detailed product performance and designparameters. The students aim to use the knowledge gained for inclusion in their dissertations whichgo towards their final-year results.

Feedback was positive from allconcerned with discussions nowtaking place between Hevac andDIT with a view to furtherdeveloping the programme.

The award is named in memory ofBrecan Mooney who was active in the research and promotion of

geothermal energy in Ireland up to his deathin November 2009. It aims to continueBrecan’s work by showcasing excellencein geothermal system design andinstallation in Ireland. In this, the inauguralyear of the competition, the award waspresented for the best domestic heatingsystem in operation since before January2010, submitted for assessment in 2011.

The winning system installed in Seanand Mary McDonald’s home by EurotechRenewables uses an open-loop systemcomprising two wells. The first well takeswater from the ground which then passesthrough a heat exchanger connected totwo Ochsner heatpumps. Thermal energyis extracted from the groundwater for thepurposes of heating the house.

A third heat pump extracts heat from the bathroom exhaust air to heat thedomestic hot water. The cooled water isthen recharged back into the groundthrough the second well.

The standard of installation in thisproject is exceptional. All heating plant and ground wells are easily accessible formaintenance and observation. The heatingpipework systems are fully insulated andall equipment is clearly labelled. Operatinginstructions and installation manualsprovide clear guidance on system use.

The operation of the heating system is very efficient, resulting in a low-energy,low-cost system for the owners. Theprimary energy operational rating of thishouse is 88kWhrs/m² each year, placing itat B1 on a building energy rating scale.The installation is saving 8,053kgs of CO2emissions per annum when compared to aheating system that uses oil-fired heating.

Analysis of the system’s energyperformance characteristics indicates thatthe cost of heating the house is at leastone quarter of that which would have

arisen from using an oil-fired boiler.Sean and Mary McDonald both feel the

comfort levels in this house are very muchimproved from any house they have everlived in before. The family also feel thesystem has benefited the family's health,as the relative humidity in the house is not affected by heating system.

Certificates of meritCertificates of merit were awarded to these companies and homeowners forinstallations that were of comparablequality and performance to the winner, anddeemed to be worthy of recognition andpromotion. These were:

• Wind Water Solar Energy Systems Ltdfor the installation at the home of JochenGerz and Laurence Vanpoulle ofDerryquin, Co Kerry;

• Green Renewable Heating Ltd for theinstallation in the home of Anne Murphy of Castlequin, Co Kerry;

• Alternative Heating & Cooling Ltd forthe installation in the home of Nick andAnne Ross of Brook Lodge, Co Cork.

Carrier’s Aquaforce liquid screw chillers are the premium solution forindustrial and commercial applications where installers, consultants andbuilding owners require optimal performance and maximum quality.


The units are designed to meet current and future requirementsin terms of energy efficiency, noise levels and reliability, and usethe latest technological innovations pioneered by Carrier. Theyare also simple and easy to install, thereby affording additionalsavings and less system downtime.Features and benefits include:– Twin-rotor screw compressor equipped with a high-efficiency

motor and a variable capacity valve that permits exact matching of the cooling capacity to the load;

– R134a refrigerant with zero ozone-depletion potential;– Low-noise generation IV Flying Bird fans made of composite

material;– Aluminium micro-channel heat exchangers (MCHX) or

copper/aluminium coils (option);– Touch-screen Pro-Dialog control system.– Extremely high full-load and part-load energy efficiency;– All aluminium condensers with micro-channels (standard

version);– Flooded multi-pipe evaporator to increase the heat exchange

efficiency;– Electronic expansion device permitting operation at a lower

condensing pressure and improved utilisation of theevaporator heat exchange surface (superheat control);

– Economiser system with electronic expansion device forincreased cooling capacity.Options available include DX free cooling; total or partial heat

recovery; factory-fitted chilled water pumps; condenser coil anti-corrosion protection.

A key element of Aquaforce is the new generation Carrier 06Tscrew compressor that benefits from Carrier’s long experience inthe development of twin-rotor screw compressors. It is equippedwith bearings with oversized rollers, and oil pressure lubricated forreliable and durable operation, even at maximum load. A variable

control valve controlled by the oil pressure permits infinitely-variable cooling capacity. This system allows optimal adjustmentof the compressor cooling capacity and ensures exceptionallyhigh stability of the chilled water-leaving temperature.

The compressor is equipped with a separate oil separator thatminimises the amount of oil in circulation in the refrigerant circuitand, with its integrated silencer, considerably reduces dischargegas pulsations for much quieter operation.

From an energy efficiency point-of-view, the MCHX heatexchanger used in Aquaforce is approximately 10% more efficientthan a traditional coil and allows a 30% reduction in the amount ofrefrigerant used in the chiller. The low thickness of the MCHXreduces air pressure losses by 50% and makes it less susceptibleto fouling by sand than a traditional coil. Cleaning of the MCHXheat exchanger is very fast using a high-pressure washer.

Apart from performance efficiencies and reduced energy usage,compliance with, and support for, environmental considerationsare equally important. Hence the use of R134a refrigerant, arefrigerant of the HFC group with zero ozone depletion potential.

Control and management of the installed system is also critical.With Aquaforce the Pro-Dialog control combines intelligence withoperating simplicity. It constantly monitors all machine parametersand precisely manages the operation of compressors, electronicexpansion devices, fans and the evaporator water pump foroptimum energy efficiency. Aquaforce is also equipped with anRS485 serial port that offers multiple remote control, monitoringand diagnostic possibilities.

With nominal cooling capacities of 270kW up to 1700kW,Carrier’s Aquarforce 30XA high outdoor temperature air-cooledliquid chillers offer a very cost-effective, energy-efficient range ofsolutions for a broad range of applications.

Every time a compressor starts, itexperiences a very large in-rush currentbefore settling down to a steady state. By minimising these start-ups, the in-rushcurrent can be prevented, therebyreducing the total power consumption ofthe system. Through this, inverter-drivenchillers can achieve seasonal efficiencies(ESEER) in the region of 5.5 - 6. Whilethese units do require an additionalcapital outlay, the part-load savings aresufficient to significantly reduce thepayback period.

Low noise at part-load, high-precisioncontrol of leaving water temperature, and quick response times to changingconditions are all well-known advantagesof inverter compressors. Each one stemsfrom the ability to change the speed ofthe compressor to exactly match therequirements, moment to moment. Over 70% of a chiller’s life will be spent in part-load conditions so the ability toperform well in these changing conditions is essential.

It is this flexibility and ability to copewith changing conditions, be it ambientcondition or load, that allows the inverterchiller to achieve large savings comparedto a fixed-speed chiller.

In addition to these well-documentedadvantages for part-load efficiency,inverters also offer a number of otheradvantages. Each stop/start puts thecompressor under significant mechanicalstress, so preventing these stop/startsextends the life of the compressor andhence the chiller as a whole. Thisreliability also makes annual

maintenance easier and cheaper formany years.

Often with units that draw a largeamount of power, such as large chillers,power factor becomes a problem. Powerfactor is the ratio of real power flowing to the load divided by the apparent powerin the circuit. When large sites have a low power factor, 0.8 – 0.85, it causesproblems for the power supplier as it hasto generate a higher current to deliver thesame useful power. This means higherinvestment in power plants, distributionsystems and cables. Often powercompanies charge penalties when acustomer’s power factor drops too low.

With inverter-driven units this is alwayskept at >0.95, thus helping the end-useravoid potentially-large penalties. So as

well as consuming less overall power, aninverter chiller can prevent the powerprovider charging additional penalties tothe client.

By using inverter technology, Daikin’sinverter-driven large chillers (EWAD-CZ)can achieve seasonal efficiencies(ESEER) of up to 5.8. These are amongthe best in the market for units with screwcompressors. When combined with alarge array of options, including full andpartial heat recovery, the result is a veryversatile and energy-efficient chiller.

For 2012, Daikin can offer air cooled,inverter-driven chillers from 5kW to63kW, and 300kW up to 1,800kW.

Contact: Daikin Europe Ireland Office.Tel: 01- 642 3430; email [email protected] �

As part of the increased trend towards energy efficient solutions in the HVAC market,

inverters (or variable frequency drives) have become more and more commonplace.

Inverter-driven units increase the part-load efficiency by slowing down the rotation

speed of the compressor. This requires less power, as well as reducing the number of

stop/start operations the unit goes through.

MAKING MODERN LIVING POSSIBLE


Because of Avocent’s industry-leading portfolio of software,hardware and embedded

technologies, it requires exacting indoorclimate control over its entire operation. Italso has to be high-performing and energyefficient. Hence the major challenge facedby Avocent’s Shannon-based plant whenchanges in F Gas legislation required thatexisting R-22 chillers be replaced by newregulation-compliant equipment.

Having carefully considered the situationAvocent appointed Sirus Air Con to overseethe entire project. Sirus had alreadysuccessfully delivered projects of a similarnature, including Penny’s in Cork and theIrish Aviation Authority in Shannon. Theappointment included configuration,planning, procurement, management,installation and final commissioning.

To begin with, Sirus carried out a fullbuilding energy load assessment whichshowed that most of Avocent’s ventilation,fresh air make-up, heating and coolingwere provided by nine roof-top air handlingunits. This comprised two large units foropen-plan office areas, individual offices,meeting rooms, reception and the staffrestaurant etc on two floors, and sevensmaller units for production andwarehouse areas.

Further analysis resulted in the decisionto address the high energy consumption of

the existing units by replacing them withreversible heat pump technology. Theselected approach was to install two250kW water-based Hitachi Samuraireversible heat pump chillers to providecooling in summer and heating in winter.Reversible heat pump technology waschosen rather than a conventional chilleras it improves winter performance of theheating of the building, and reduces

energy consumption by reducing the useof the much less efficient LPHW boiler(COP less than 1). The LPHW is now onlyused as a top-up.

A water-based heat pump system waschosen over a DX solution as higherefficiencies could be achieved by havingtighter control using water systems.

Sirus used their expertise in buildingenergy management systems to tie thecontrols of the new heat pumps into theexisting site system and provide Avocentwith very accurate control of the heatingand cooling systems for their facility.

The new heat pump units – mounted onnew structural frames with associatedbuffer vessels, twin pump sets and heatexchanger coils – were individually craned into position and installed over two weekends. The only downtime on the existing roof top units was during theremoval of the old DX coil and installationof the new water-based coil.

The pipework was pre-fabricated off-siteand required final adjustments and weldingof a minimum number of joints in-situ.Optical pressure and temperature gaugeswere installed for future maintenance.Pressure and temperature transducers wereinstalled, together with 3-way flow controlvalves for connection into the existingbuilding management system to providethe necessary control. The system wasthen filled, commissioned and set to work.

The new high efficiency reversible heatpump units and system modifications willprovide a performance gain ofapproximately 30% over the existingchillers and system. Approximately 20% of savings will derive from improvements in plant performance, a reduction in plantsize and greater plant operating control.Additional savings will come from reducedbuilding energy loads. Changes to theHVAC and BMS system will allow facilitymanagers to heat and cool the building in a more efficient manner than previously possible.

Throughout the project Sirus and Hitachiworked very closely to ensure that all theworks, right up to final commissioning,were carried out switfly and with little or no disruption to Avocent’s operations. �

HEATING – ACONSTANT REQUIREMENT

FREE HOT WATER,NOTHING IS LOST,

EVERYTHING IS RECOVERED

TOTAL HEAT RECLAIMA simple principle: if there is a demand for

heating, the hot gases leaving the compressor aredirected towards the heat reclaim condenser, thegases give up their heat to the hot water, leaving

the condenser at a temperature of up to 60oC.100% of the heat rejected by the chiller can beused to produce the hot water required by your

installation. When the demand for heating issatisfied, the hot gases are automatically directed

to the initial air condenser circuit where the heat isrejected to the air by the fans. �

PARTIAL HEAT RECLAIMAt a leaving temperature of up to 80oC this system is

particularly suited to the production of sanitary hot water. A heat exchanger placed upstream of the condenser ensures

the desuperheating of the gases before they enter thecondenser. Another advantage, available with the Aquasnap

heat pumps: the system guarantees sanitary hot waterproduction all year round, summer and winter. �

NATURAL ECONOMICALHEATING

Heat reclaim is often associated with the generation of solarheat; it offers energy savings and is a significant step forward

towards safeguarding our environment. �

Why reject and lose the heat generated by therefrigeration system and not benefit from it free-of-charge? In many activity sectors, such as agriculture,the food industry, industrial processes, hospitals andhotels heat reclaim permits a considerable reduction

of the energy bill for the heat generation equipment.This controlled optimisation contributes towards aresponsible commitment to reduce waste energy and the harm done to our planet. �

New iVECTOR intelligent heating from Myson

The iVECTOR was designed tooperate efficiently even with low flowtemperatures. This means that it is a cost-effective option for use with both traditionalboilers and renewable technologies.

With renewable installations such as heatpumps, iVECTORs are a viable alternativeto underfloor heating or radiators, and canbe installed in different rooms or on separatefloors of the same building. This is becauseall products can operate using the samelow flow temperatures.

For systems with traditional boilers, highoutputs can be achieved making it ideal fordomestic and commercial applications. Thelower water content inside each iVECTORmeans that it produces an instant heatresponse where needed and cools quickerwhen heat is no longer required.

iVECTORs, therefore, waste minimalenergy and have lower lifecycle costs thanother fan convectors, making them arealistic alternative to traditional radiators in refurbishment projects.

The iVECTOR’s low water contentmeans it is able to respond almostimmediately, rapidly heating or coolingrooms as required with minimal energywastage. It utilises a high-efficiency heatexchanger, intelligent controls and fan-

assisted convection. This powerfulcombination means it can provide a fast,accurate and co-ordinated response to the heating requirements of every room in a building.

The large surface area of the iVECTOR’sheat exchanger means that units arecompact in size and occupy less spacethan a panel radiator of equivalent output.By utilising fan convection, the iVECTORalso provides an even distribution of warm

air throughout a room, meaning that roomsfeel more comfortable, even at lowertemperatures.

In winter months, the iVECTOR rapidlysupplies warmth and can automaticallyswitch to cooling during the summer whenfitted with a reverse-cycle heat pump. Theelectronic thermostat in each iVECTORclosely monitors temperatures room byroom and controls the fan speed toaccurately maintain temperatures at thedesired comfort level.

The intelligent, electronic control systemin every iVECTOR provides a wide range of easy-to-use heating and coolingoperating options. Its two-tier level ofprogramming incorporates an “easy” mode for everyday operation and a “full”mode for more advanced functions.

Main control features are:

– Each iVECTOR is individually programmable;

– 24/7 programmer with 1-hour time periods;

– Lockable LCD backlit display;

– Automatic and manual options for control of fan speeds;

– Option to link to building management systems;

– Night set-back function;

– Programmes saved in memory for 12 hours in event of power failure.For more information on this new

product, or any of the emitters or controls inthe Myson range, please contact the salesoffice in Potterton Myson at Tel: 01 – 459 0870; email: [email protected]; www.potterton-myson.ie �22

The iVECTOR is Myson’s latest product innovation and the first in a new generation of intelligent fan convectors. It has been designed specifically to combine all thetraditional advantages of a fan convector with a range ofnew product features made possible by the latest energyefficient heating technology.

iVECTOR’S controls are intelligent andeasy-to-use.

iVECTOR’S low watercontent means it is able torespond almost immediately,rapidly heating or coolingrooms as required withminimal energy usage.

The four-minute animation focuses on a modernschool building and shows how easily air and water sourceheat pump systems can be incorporated into a building towork alongside, or replace, traditional heating systems.

“We have used a school because of the high demand for heating, but the technology is suitable for almost anycommercial building,” explains Mike Sheehan, DivisionalManager for the company’s Living Environmental SystemsDivision in Ireland.

Mitsubishi Electric has developed a range ofsystems that can supply a building’s hot water andheating. The units offer complete flexibility of designand can work alongside current technologies to allowa building to achieve renewable energy targetswithout major upheaval.

Three models are shown in the animation startingwith the flagship, award-winning Ecodan® CAHV-P500YA-HPB, which is scalable from 43kW to 688kW.

The MCS Approved (Microgeneration CertificationScheme) air to water heat pump uses advanced air source heat pump technology to provide a building’sheating and hot water.

The monobloc CAHV unit is a factory-sealed systemwith two separate refrigerant circuits, which overcomes the issue of the heat pump defrost cycle and ensures thatheating capacities can be maintained accurately andreliably all year round.

For every 1kW of electricity consumed, an average of3.2kW of usable heat is generated and supplied to the

building. The CAHV can provide heating and hot water either on its own or in conjunction with othertechnologies and can work particularly well withcommunity heating schemes.

The animation also highlights how the CHU air sourceheat pump and the CHQ ground or water source heatpump systems bring flexibility into the design process for building specifiers and architects.

Both systems link to the unique Ecodan CAW heat pump boiler via refrigerant piping to transferconverted renewable heat energy into heating andhot water for the building. The CAW unit has beenspecifically designed to fit easily into existing plant rooms.

“We have built a range of products that will help both new-builds and existing buildings to achieverenewable energy targets for heating”, explains Sheehan.“We have also designed these to work alone or alongsideexisting systems to provide complete flexibility for buildingdesigners and operators.”

The animation is available onYouTube(www.youtube.com/ watch?v=KuPVoMolzxo<http://www.youtube.com/watch?v= KuPVoMolzxo>) or on the commercial heating website, along with furtherdetails on the company’s complete range of commercialheating solutions. �

Mitsubishi Electric has just launched a short animated film to highlight how easy itcan be for both existing and new-build commercial buildings to achieve renewableenergy targets with the company’s range of commercial heat pump water heatingsystems.

To that end it began by building astate-of-the-art climate chamber at its Cooleamanufacturing facility in Co Cork. It is builtaccording to the guidelines set down in theEN14511 standard, which also specifies theconditions under which the heat pump istested and evaluated.

The chamber allows for testing attemperatures between -30°C to 60°C withhumidity levels up to 100%RH, and a heatpump capacity up to 100kW. It is also possibleto simulate rain and snow, which is especiallyuseful in determining the effectiveness ofdefrosting.

While this involved considerable investment,it gave its engineering team – led by specialistconsultant Mervin Burns – total control andthe flexibility and freedom to do highly-calibrated, evidence-based, testing andresearch. It also means that Mark can have all its heat pumps tested and accredited by an approved test organisation at its ownmanufacturing plant.

The result of this investment and extensiveresearch is the new range of Mark heatpumps now coming off the production lineand which will be ready for marketplacedelivery early in the new year.

The first model to be introduced is the15kW air-to-water unit, which will befollowed shortly by a 15kW geothermal unit.These will then be supplemented withadditional units, offering similar configurationsof varying capacities, over the course of 2012.

The Mark heat pump is of monoblockdesign and comprises a self-contained unitincorporating variable speed control, variablespeed compressor, a small buffer tank, and awater circulation pump, all of which are builtin. Due to the careful positioning of internalcomponents, the unit’s physical footprint hasbeen greatly reduced, making installationquick and easy. It is suitable for installation atground level or mounted on wall brackets,with noise kept to a minimum thanks to low-noise fans and acoustic padding.

Through the process of building a prototypeunit and constantly testing it in the climatechamber – and making design changes basedon data collected – the Mark developmentteam came to the conclusion that the coreconcepts behind mainstream heat pumptechnology could be considerably improved on.

Mark Eire pioneersnew developments in heat pumptechnology When Mark Eire decided to enter the heat pumpmarket its objective from the outset was notmerely to replicate existing technologies but ratherto innovate and pioneer new developments. Thecore idea was to design and build a heat pumpthat was high-performing, energy-efficient, simpleto install and cost-competitive in the marketplace.

History in the making– the first Mark heatpump coming off theend of the productionline at Mark’smanufacturing plantin Coolea, Co Cork.

This led directly to some notable changesin the basic fundamentals behindestablished heat pump technology. One ofthese was the decision to integrate modern,brushless, direct-current (BLDC) rotarycompressors, driven by variable speed dcdrives, into the unit. This makes for ahigher-capacity, lower-running-cost, high-efficiency unit.

In addition, the dc drive is custom-built toMark’s own specifications. This means thatwhen the heat pump is running the unit hasfull and variable control, right down to lowspeed, which is not normally possible withexisting compressor technology. As a result,the Mark heat pump will run only at aspeed necessary for the requirements, asopposed to switching on and off to fullspeed like many mainstream units do.

Other features incorporated into theMark heat pump are electronic expansionvalves and variable speed control on outdoorfans. These features all contribute towardsthe efficiency of the Mark heat pump.

However, according to Mark EireManaging Director Mike O’Donoghue,

designing and building the ultimate heatpump is only part of the equation. Equallyimportant is the service back-up provided.Mark has been operating in the Irish marketfor 25 years and prides itself in the level ofsupport it delivers to installers and servicepersonnel on its traditional product lines.

This same level of support will beprovided in respect of heat pumps. A specially-adapted heat pump trainingprogramme has been devised which willcover heat pump technology in general, inaddition to specifics on the Mark unit, alongwith installation and service guidance. Thiswill include everything from basic positioningto control set-up and commissioning.

“As all installers of Mark heat pumps will have completed our intensive inductionand training course”, says MikeO’Donoghue, “homeowners can restassured that they are buying more than justa heat generator. This is essential for theheat pump market as it is still a fledglingindustry sector.

“With a properly-installed andcommissioned heat pump, the homeowneris more likely to recommend the heat pumpconcept to others. It is only by deliveringquality products, that are properly installedand commissioned, that all of us operatingin the sector can hope to benefit. We atMark Eire are confident that we can nowdeliver to that demanding criteria and, inthe process, capture a significant share ofthe developing heat pump market, bothhere in Ireland and internationally.” �

The current range of Wilo high-efficiency pumps are“ErP-ready”, which means they meet these new requirements,and indeed are future-proofed in that they also meet therequirements of the second stage of the same EU regulationwhich is due to come into force in 2015.

The Wilo-Stratos, Wilo-Stratos Pico and Wilo Stratos-Gigahigh-efficiency pump series offer a comprehensive range ofproducts for various building services and related requirements.This range of products already exceeds all the stricter newrequirements which will be applicable as of 2015.

This is due to Wilo high-efficiency pumps already havingextremely low power-consumption values because of theiradvanced electronic control and innovative EC motortechnology. These electronically-controlled circulating pumps, with relatively maintenance-free frequency converters,automatically adjust their power to the changing loadrequirements of the relevant systems.

This is especially true when the pumps operate in partialload conditions, which can make up as much as 94% of theoperating time of a circulating pump. A very considerablereduction in power consumption can be achieved under such operating conditions when compared with anuncontrolled pump.

The EC motor technology (ECM) is the most modern variantof the DC motor and is characterised by particularly highenergy efficiency. This allows the efficiency to be doubled in comparison to electronically-controlled pumps usingconventional drives motors.

The Wilo-Stratos has already set standards since its launchin 2001, and the total Stratos series for heating and coolingcircuits in commercial properties has been continuouslyexpanded and optimised since then.

The Wilo-Stratos Pico high-efficiency pump, introduced in 2009, is primarily designed as a heating pump for residentialapplications, but can also be used in air-conditioningapplications. With an energy saving potential of 90% incomparison to uncontrolled standard pumps, the Picoconsumes approximately half as much power as that requiredto meet the current top energy efficiency Class A rating.

The Wilo-Stratos Giga is the latest addition to the range,

making it possible to have a high-efficiency pump that covers the upper performance range in heating, cold-water and cooling applications.

According to Wilo, approximately 8,000 kg CO2 per year, as well as up to e85,000 electricity costs per installed pump, can be saved with the Wilo-Stratos Giga in a 15-year operating cycle compared to conventional uncontrolled pumps (based on the load profile “Blauer Engel”).

The Giga series is a completely new development. For the first time glanded pumps can be driven by extremely power-saving EC motors, with the pump’s hydraulics optimallymatched to the motor technology. Giga was awarded the “iFProduct Design Award" even before it was presented for thefirst time at the ISH trade fair in March 2011.

Wilo’s high-efficiency pumps are suitable for use in manydifferent types of building services circulatory systems, and are ideally suited for use on heating and cooling systemswhere innovative design and energy efficiency should be a pre-requisite for the end user.

The full range is available through Wilo’s extensivemerchant and distributor network throughout Ireland.

The new EU regulation which became law in May of this year governsthe energy efficiency of all electric motors sold after June 2011, andglandless heating pumps sold after 1 January 2013. Up to 90% energysaving potential can be found in building distribution systems for heatingand air-conditioning if high-efficiency pumps, with particularly low powerconsumption, are used instead of inefficient, uncontrolled, glanded andglandless circulation pumps.

heating sector thanks to its strong partnership with Daikinand the latter’s industry-leading status in heat pumps.

Airflow Services was in a unique position to capitalise onheating and renewables thanks to its experience andexpertise across a wide range of HVAC systems, fromdesign right through to commissioning. It now providesprofessional, practical, cost-effective advice and services onenergy efficiency and related matters to both the domesticand commercial sector.

It has provided HVAC performance/energy surveys,building energy rating reports and air leakage testing for anumber of years so, to now deliver comprehensive heatingsolutions using Daikin’s Altherma is a natural development.Daikin has over 50 years experience with heat pumps andprovides more than a million units to homes and commercialapplications throughout the world each year.

People in Ireland are now more energy-conscious andenvironment-aware than ever and are looking for heatingsolutions that are not just renewable but also cost-efficient tooperate. Given that two-thirds of the heat generated byDaikin’s Altherma air source heat pump is free, and thatmaintenance of the system is minimal, this is an obviousalternative to traditional boiler-led installations.

As for domestic hot water requirements, the Althermatechnology is equally advanced. The unique lay-out andspecial placement of the system components maximisesenergy efficiency. The water inside the storage tank isprimarily heated by thermal energy from the outside air,thanks to a heat exchanger connected to the heat pump.However, an additional electrical heating element in thedomestic water tank provides extra heat if required in theshower, bath or sink. At necessary intervals the water isautomatically heated to 70°C to prevent the risk of bacteriagrowth.

While heat pump technology is tried, tested and proventhroughout the rest of Europe, it is a newly-emerging industrysegment in Ireland. Airflow Services is spearheading itsdevelopment and market penetration and, to that end, hasparticipated in numerous home-build exhibitions.

In partnership with Daikin, it has also kitted out a specially-designed mobile trailer which features a fully-functioningDaikin Altherma heating system. This is used to portray the

features and benefits of heat pump systems to bothconsumers and installers alike. Reaction at the latest outing– the Self-Build Show in Cork – proved very encouragingwith quite a number of very positive leads generated.

“While at a relatively new stage in terms of marketpenetration, our experience of late is that heat pumps arenow very much on the agenda of most discerning installersand householders considering a new or replacement heatingsystem”, says Airflow Services Design Engineer JamesO’Donoghue.

“They display a level of awareness of heat pumptechnology that demonstrates a genuine interest and we areconfident that, with the quality of the services we providematched by the quality of the Altherma system, we willconvert a large percentage of the leads in hand.”

Richard Sherlock of Daikin is equally upbeat about thenew-found status of heat pump technology. “In recentmonths there has been a noticeable shift in the type ofquestions posed. Consumers and installers no longer askwhat heat pumps are but instead ask probing questionsabout installation, applications suitability, performanceefficiencies, energy outputs and actual running costs. Whileembryonic, the heat pump market is now a viable marketsegment and we are confident that, together with our dealerpartners such as Airflow Services in Cork, we can developand realise its full potential”. �

Every system is individually-designedand supplied with full mechanical andelectrical CAD drawings. Indeed, a keystrength of the service provided is its abilityto interface with, and support, both theelectrical contractor and heating installer,right through to final commissioning.

The product portfolio includesestablished, market-leading, brands such

as Alpha, Solartherm, Daikin, MitsubishiElectric, Oventrop and Worcester Bosch.The choice of solutions offered isextensive, with products and systemsavailable to cater for all manner and size of application.

Unitherm can design systems usingcombined heat sources such asSolartherm panels, heatpump and a boileror solid fuel stove etc. This can beachieved through their Eco-combi multi-energy tank which will allow up to threeheat sources. The whole system can becontrolled by using an advanced MerlinControl & Regulating Unit which combinesvarious open-loop and closed-loop controlfunctions. In addition to the weatherdependent control of the boiler and theheating circuits, it naturally also controlsthe hot water supply, allowing hot water to be controlled at various times andtemperatures over a 24-hour period.

On the boiler side, Alpha high-efficiencycondensing boilers offer a comprehensiverange of Sedbuk Band A ratedcombination, system and regular gasboilers with outputs from 12kW up to115kW. Apart from new installations, theAlpha range is ideal for retrofit andrefurbishment as older, inefficient boilerscan be replaced without the need toreplace pipework.

Alpha has a pedigree going back 40years with a reputation for constantlyintroducing innovative productsincorporating cutting-edge technology. This is particularly true of its renewablesproducts which are specifically designed to

be compatible with the core boiler ranges.The Alpha GasSaver, FlowSmart andAlpha SolarSmart are typical examples.

GasSaver is easily installed between theboiler and the flue and delivers hot watersavings of up to 37% and gas consumptionreductions of as much as 52%. It alsoreduces pluming as gases expelledthrough the terminal are significantlycooler, which in turn saves energy andhelps the environment.

SolarSmart also delivers impressiveenergy-related savings by making solar-based domestic hot water heating moreaccessible and cost-effective than everbefore. The system consists of a solarcollector panel, drain-back unit, solarcylinder and solar valve. All items areWRAS approved and come with a 10-yearguarantee, provided all recommendedinstallation guidelines are followed.

Then there is the Altherma air to waterheat pump from Daikin. Using proven heat pump technology, Altherma utilisesnaturally-occuring energy from the air and uses this to provide domestic spaceheating and hot water. It is easy to installand reduces CO2 emissions by up to 50%while delivering savings of 30% on homeheating running costs.

Meanwhile Worcester Bosch is one ofEurope’s longest-established heat pumpspecialists with a reputation for developinginnovative heat pump solutions dating backover 30 years. It offers an extensive rangeof heat pumps designed to extract heatfrom everything from soil, rock, water andoutdoor air right through to ventilationexhaust air. It also has a strong history ofcollaborating with other world-leadingbrands in related areas of expertise.

Taken together, the foregoing representswhat is undoubtedly one of the strongestheating portfolios available in Ireland.When combined with the expertise andexperience of Unitherm Heating Systems’personnel, it makes for a formidablemarket force offering infinite heatingsolutions for all manner of application.

Message from the CIBSE Chairman

We were extremely honoured to host a visit by Ron Jarnagin, President of ASHRAE in early October. This visit was particularly successful due to the combined efforts of

the CIBSE Committee, DIT, TCD and Engineers Ireland. Between us we arranged a lunch, a tour of the Engineering Faculty and Campus at TCD, and an address at Bolton St, followed by a dinner in the President’s Room at Engineers Ireland. This collective effort underpinned and reinforced the CIBSE theme this year of an integrated approach to engineering and the built environment.

Other events of note in Autumn 2011 included Christopher Cuttles CPD on lighting design at DIT Kevin St; David Wolahans CPD on Compressed Air at DIT Bolton St; the Young Lighter and Irish Lighter Awards at DIT Kevin St … not forgetting the extremely enjoyable annual golf outing at Edmondstown Golf Club in September.

In terms of reporting our activities to CIBSE HQ, I delivered a presentation to the CIBSE Council in Balham in October, where I outlined the committee’s activities, technical evenings, awards and new publications. This presentation was well received and we secured CIBSE President, Andy Ford, to attend our annual conference which will take place in Croke Park next March.

Our programme for 2012 is taking shape, and aims to include a wide range of areas which we feel will be both interesting and relevant to our sector. We also intend to host some of our events in other venues such as Engineers Ireland, in addition to the DITs.

Our new website in under construction and will go live in December, just in time to capture our programmefor 2012, and share our experiences from 2011.

Finally, we are very proud to have delivered and published the first edition of the SDAR* Journal. This wasa combined effort between CIBSE and DIT Kevin St, with sponsorship support from Airtricity. This industryfirst was a major achievement for all concerned and was circulated to CIBSE members, and the industry atlarge, through bs news. The intention is to publish a second edition in 2012, and we welcome papers forconsideration.

CIBSE always welcomes new members. Please go to the main CIBSE website, www.cibse.org or email us at [email protected] for further details.

Derek Mowlds, CIBSE Chairman, Republic of Ireland Region

As we approach the end of 2011, it is appropriate toreflect on the busy and productive schedule ofevents completed thus far in the CIBSE calendar. It is also important to do so in the context of next year as we look forward to an equally-intensive programme for 2012 covering a widerange of technical, engineering and other related topics.

ASHRAE President Ron Jarnagin was in Dublin recently for a visit jointly hosted by CIBSEand DIT Kevin St. Ron’s term began when he wasformally elected to the post in June of this year and such is his commitment to the role that he hasalready criss-crossed the globe delivering hispresidential theme not just to members, but alsothose of other building services-related organisations.

That theme is “Sustaining Engineering SocietyThrough Leadership”, something which Ron isabsolutely passionate about. In describing his vision of what leadership entails, he quoted Dwight D Eisenhower who said: “Leadership is the art ofgetting someone else to do something you want done because he wants to do it” … think about it!

While Ron is primarily concerned with ASHRAE,his approach is equally applicable to CIBSE, andindeed to all other industry representative bodies,especially those run on a voluntary basis.

He cited three core pillars upon which he hopes to develop this leadership role.

The first is developing future leadership and theemphasis here, he said, should be on devising aneducation system that takes students beyond just

the basics. In addition to load calculations and theother fundamentals, he said students should learnabout modeling and system selection.

He also suggests that it is vital to consciouslydevelop students’ ability to lead. He said studentsshowing leadership qualities should receive moreencouragement and support to develop. His idea is to assign them to some of the Associations’ officers,to get them to attend committee meetings where they can network, and to show them how the system works.

In doing this he also talked of the importance of the “old guard” learning to communicate withstudents using today’s technology such as text,iphone, Facebook and Twitter.

The second major pillar Ron talked about wasbuilding a global presence. “We’re a globalorganisation”, he said, “an international organisation,and I think we need to start doing some things to help realise that. One clear need is to better supportour international members, and also to developpartnerships with other bodies such as CIBSE.

“We’ve already worked very closely with CIBSE todevelop Building eQ, the ASHRAE building labelingsystem, and also on research activities. We’ve hadsome discussions about further collaboration and I’m looking forward to more of this in the future.The third and final pillar of the leadership role isstrengthening the industry. Quite simply, he saidengineers have to do a better job in their designs;contractors have to do a better job putting designstogether; commissioning agents need to make sureeverything works as intended; and then they’ve got to make sure the owners are fully trained.

“This is our responsibility and we need to bring ourpartners together to help. Remember, you don’t haveto start every parade, you just sometimes have to beable to jump in front of it if it comes by, and that’sokay too in my book”, he concluded. �

For companies to survive in an ever-challengingmarket they must offer good value to clients.Could value be improved in your company byestablishing a research base?

At DIT we believe it is necessary to move from ideologically-basedinnovations to low energy solutions offering proven value. This can be done withpost-occupancy evaluations and similar applied research themes.

Of course, you are thinking that the related fee structure and marketcompetitiveness does not allow this. Well maybe this can be achieved bycollaborating with research students? Research students are time rich and datapoor. The probability is that your company is data rich and time poor.

If your company has research questions or access to post-occupancy energydata, then we would like to hear from you with a view to establishing researchcollaborations. Students are data poor and need access to data in order to beable to perform good quality research.

We have students on the following programmes looking for access to data:– PhD/MPhil research;– MSc in Energy Management (for theses and shorter assignments);– BSc (4-year honours degree) in electrical services and energy management

(for theses and shorter assignments); – B Eng Tech (3-year degree) in sustainable design of electrical services engineering (for theses).

We would be happy to collaborate with you to help you answer your research questions. There are benefits for your company, the industry, DIT and the students involved – it really is a WIN-WIN-WIN-WIN scenario.

Three of the authors in the SDAR* Journal (http://eleceng.dit.ie/sdar/ index.php?go=sdar_journal) are from the above-listed programmes.

You can see the beginnings of our vehicle for research in the School of Electrical Engineering Systems in DIT (http://eleceng.dit.ie/sdar/). You might consider joining with us on this. There is no cost and the

projects on your books could provide students with access to data that could fill many theses, while also answering important questions for your company.

I guess youcan’t help but

get caught up in the positive

feelings that surroundthe recent great

performance of the Irish soccerteam … what they have achieved

has been phenomenal.Everyone knows they will

do us proud and no doubtadvertising agencies all over

the country are looking atways that their customer’s

brands can benefit by apositive association with“Trap’s Green Army”.

This got me thinkingabout some of the soccerclichés that abound at a time like this and onestood out for me – hehas a “great engine” –

referring toaboundingenergy

levels thatplayers display.

In the context ofthe loyalty and

commitment the current squad hasdisplayed, this can be furtherembellished to a “great green engine”.

So, what have we in the heatingsector got that gives us a positiveassociation with Trap’s Green Army?Our gas and oil boilers certainly havegreat engines and, more to the point,they are also green.

All leading gas and oil boilermanufacturers produce high-efficiencydomestic and commercial boilers withintelligent controls, hot watercylinders, and a wide range ofrenewable technologies that deliverlow energy consumption, and reducedoperational costs and carbon footprint.So, we have the “great engine” bitcovered with our HE boilers, and wealso have the “green” covered.

We all know how difficult theheating and hot water market is rightnow, and that it will continue to be sointo 2012. So, as an installer and/orservice engineer you should beplanning promotional campaigns and,what better way than by tapping in tothe positive “green army” momentum.

Why not develop a simple flyer, asticker for the van, or place an advertin your local paper that captures thistheme. Keep it simple and light-hearted but with a clear, directmessage. Use our Trap illustration to get you started. �

The evolution of building designthrough the last 20 years or so hasseen a progression from draughtingto computer-aided design, fax toemail and hard copy to digitalformat documentation.

Building information modelling(BIM) introduces a new concept that seeks to harness the wealth of technological advancement thathas occurred during the last twodecades into a holistic designsystem. The ambition is to improvethe efficiency of the design process,to give better information to allstakeholders with a shorterturnaround, and to enable clients tomaximise the full range of serviceswhich their design teams can offer.

Too often, the project fee hasdetermined the level of analysis thatcan be carried out as it is too costlyfor architects and engineers to carryout multiple iterations of analysis onvarious elements of the design.With BIM that has become possible,writes Keith Mellon, MechanicalProject Engineer, Ethos Engineering,and CIBSE Committee member.

The ability to carry out multipleiterations of concept design andproduce results quickly means thatclients can get more value for theirfees and engineers can deliver abetter, more-informed solutionwhich can only help the designprocess. Internal environmentalconditions can be refined at anearlier stage in the design processthrough visualisation of internallighting, adjusting the building formto counter the effect of shading fromadjacent buildings, the creation oflight wells, and the improvement ofthe building façade. This can beachieved through the use ofsoftware packages such as IESVEor Ecotect.

The concept of M&E servicesdesign through BIM is a departurefrom the current disjointed designprocess. Design calculations arecarried out in spreadsheets orsoftware programs that are notautomatically linked to the designdrawings, and thus, in turn are notautomatically linked to theschedules and quantities ofmaterials and equipment. Engineersare required to trace their stepsforward and backwards through thisprocess to ensure that the design isfully quantified, qualified, recorded,evaluated and presented.

The tracing of these steps oftenconsumes most of an engineer’stime and distracts from carrying outactual design or attending site tomonitor the installation. BIM is anintegrated design process that cancarry out design calculations,automatically produce drawingsbased on these calculations,automatically schedule equipmentand materials, and also monitor thedevelopment of the architectural,structural and civil engineeringelements of the design.

Building Information Modelling –the next step in design evolution

Within the BIM process,components are introduced to thedesign software as “families” whichcontain specific informationpertaining to a particularcomponent. A light “family” will have the specific physical size ofthat fitting; an ldt file with specificphotometric data for that fitting; anda power connector for that fittingwhich has voltage or currentrequirements and can be connectedto a cabling system.

Software programs such asAutodesk Revit MEP are suppliedwith a basic set of component

libraries containing families of someof the components used by MEPengineers. Many more of these canbe found online on websites suchas Autodesk Seek, BIM Store andRevit City. The long-term aim is that product manufacturers woulddevelop BIM libraries for theirproducts in the same way as theyhave developed CAD drawings todate. The difference with BIMlibraries is that they will containspecific performance data whichfacilitates design through BIM.

At the very core of the BIMprocess is the concept of parametricdesign, which involves thecomponents such as radiators,

lights, grilles, etc having informationthat is live and which can feed intothe various elements that connecteach system, i.e. pipework, cabling,ductwork.

Take an example of a ductworksystem. If we design a ventilationsystem which has each grillesupplied at 80 litres/second andsize the ductwork system based onthis and then, following a review ofthe calculations, determine that weonly need 60 litres/second, all of theductwork would need to be re-sizedby an engineer and re-drawn by aCAD technician. With BIM, becausethe grilles have parametric data thatthe ductwork system can base itscalculations on, simply changing

one “family” element will result inthe ductwork being automatically re-sized accordingly. Think of thetime that would save!

The production of dynamicschedules which can be easilyexported is a tremendous aid toengineers who can now producedocumentation that can be used fortendering projects, or to keep as arecord for internal quality systems’compliance checking. Theseschedules can be adapted tofacilitate a wide range ofparameters while maintaining a“live” link to the components withinthe building model, which spaceand which level they are on.

Looking at the wider picture, theevolution from 2D to 5D and XD

design is something that isinevitable to achieve the level ofsavings that are needed to makeprojects viable in today’s economicclimate. The UK has set targets of20% savings in costs and 20%reduction in carbon emissions onpublic sector projects over £5

million from 2016 onward. Theconstruction industry sees BIM asthe only real platform that canachieve this. The Irish market muststrive to have the same level ofambition and embrace theimpending evolution in design and construction practice. �

back issuesHow Smartt is that!

Congratulations to JohnSmartt, Assistant Head of Schoolof Construction, DIT Dublin, whoreceived a special award at theInstallerLive Awards ceremony in the UK recently.

As everyone knows, John hasbeen the committed champion forheating and plumbing skills notjust in Ireland, but worldwide, for many years.

This award is in recognition of his dedicated service to theheating and plumbing industry,most notably his expert input to the Chartered Institute ofPlumbing and HeatingEngineers.

Energy debate is never-ending!It has been reported that by the end of the yearSainsbury's will become the first supermarket in the UKto send all its food waste for anaerobic digestion (AD) –the process that decomposes food waste to releasebiogas which can then be used to produce electricity.Most of the other supermarkets are not that far behind.

Great idea you would think – not so say someexperts. Apparently, sending food waste to an AD plantonly recovers a fraction of the energy that went intogrowing the food in the first place. Recycling tomatoesin this way, for example, generates less than 1% of theenergy used to produce the crop.

By contrast, it is claimed to be up to 500 times betterfor the environment to divert food waste to pigs ratherthan sending it to AD. Fattening livestock on food wastereduces the need to feed them with the 40m tonnes ofsoya imported into Europe each year from SouthAmerica, where its cultivation contributes todeforestation, soil erosion, water depletion and global warming.

By the time we arrive at a consensus on what’s bestacross the entire energy debate it will be too late!

Daly does Village People… on the double! Hitachi’s Fergus Daly is known throughoutthe industry for his ingenuity and inventiveness butcolleagues, and even close friends, were takenaback at his 40th birthday bash recently when hemade a guest appearance not once, but twice – andat the same time – with Village People. I missed itmyself but, as you can see, the camera does not lie.

Brian is not shy when it comes to performing but hereally excelled himself recentlywhen compering the SEAISustainable Energy Awards inthe Conrad Hilton in Dublin.

These Awards are one of themost important in the annualbuilding services calendar ofevents and, while it is a serious,business-like occasion, Brian’s content and delivery made for a thoroughly enjoyable – and entertaining –evening.

Who needs a separate entertaineror after-dinner speaker when Brian seamlesslymarries these elements into theserious aspects of the evening?
