At last – plumbing standard to count on

The NSAI will shortly publish an Irish StandardsRecommendation, SR 50, which will be a BuildingServices Code of Practice (COP) for the heating and

plumbing trade.The COP will initially have three parts –

SR 50-1: Domestic plumbing for hot water and heating; SR 50-2: Thermal solar systems; SR 50-3: Domestic plumbing for cold water systems.

The function of the SR 50 heating and plumbing documents is to lay out a Code of Practice for plumbing works carried out on domestic dwellings using solid fuel, gas, oil and other fuelsfor heating.

This is not just a welcome initiative but one that is essentialand long overdue. That is covers all fuel types is indicative of thethoroughness with which the exercise was approached… welldone all involved (see page 19).

Whither construction and built environment?

Even in the full knowledge that the points requirements forconstruction-related college courses such as architectureand the built environment would be significantly down,

college applicants are obviously shunning the industry.Only 211 applicants listed courses in the built environment

area as their first choice this year, while demand for architecturehas also fallen back with 125 fewer first choice applicants.

While understandable to an extent, this negative perception ofthe sector needs to be urgently addressed. Such a low intakewill result in shortages in the future but, even more alarming stillis that it threatens the viability of running such courses at all. ■

In recent years, underfloor heating hasbecome increasingly popular. This is due tothe fact that underfloor heating provides a

range of opportunities not offered by traditionalheating methods, both in residential andcommercial buildings. However, underfloorheating also offers some challenges and, inorder to make the very most of the opportunities,it is important to choose the right solutions.

Why choose underfloor heating?There are many areas in the commercial sectorwhere underfloor heating can be incorporated to benefit potential clients, both in terms ofcomfort and energy reduction. Money mattersnow more than ever before, and if an engineercan effectively demonstrate to the client thatthere is the potential to reduce operating costsand provide increased levels of comfort byincorporating lower energy sources, thenunderfloor heating has clear benefits.

Some of these benefits include:– Underfloor heating provides comfortable

heating as your feet are kept warm while your head is kept slightly cooler;

– There is much focus today on the indoorclimate where increasing numbers of people are plagued by asthma and allergicproblems. Due to the large heating surfaceassociated with underfloor heating, less air ismixed and therefore less dust occurs in theroom compared to a conventional radiatorsystem with its convection currents of air;

– The room temperature can be lowered 1-2°Cwhich can result in energy savings of 6-12%;

– Low surface temperatures which eliminatecontact hazards;

– Long life span.

There are some circumstances whereunderfloor heating is not suitable and a moreconventional form of heating may be moreappropriate. This can be due to client’srequirements or perceptions, structuralconstraints or the flexibility of the space.

Some of the disadvantages associated withunderfloor heating are:– Generally it has a slower response time (in

solid floor applications only) compared toradiators;

– Incompatible with certain floor coverings;– Floor penetrations should be avoided or

carefully planned;– Difficult to change pipe routes once

installed.

Applications and design parametersThe principal characteristics of underfloorheating include energy efficiency, economy andexcellent thermal comfort. It is an ideal choicefor most, but not all applications. Table A (nextpage) lists the suitability of these applications.

Room temperaturesThe temperature experienced in a room is theresult of two different factors, namely the airtemperature and the ambient radiation, i.e. fromthe heated elements in the room. It can be anadvantage in many ways that heat radiationconstitutes a relatively high part of the “overall”temperature, or the operative temperature as it is also called.

Underfloor heating is not purely a radiant formof heating, typical emitted proportions are 70%radiation and 30% convection. If a large part ofthe operative temperature is made up of the airtemperature, it means that there will be a high

In this article Enda Gilroy gives a general overview ofunderfloor heating, discusses design parameters anddesign issues, weighs up the pros and cons of thesystems, and discusses how underfloor heating can beintegrated with different energy sources.

convection or mixing of air in the room. Ifthere is high mixing, air is whirled aroundwhich leads to higher dust content in theair and therefore a poorer air quality.

Where convection is a high proportionof the operative temperature, the frequentopening of doors or windows can have anegative impact on occupant comfort. Forthis reason underfloor is particularly suitedto foyers or atriums where the proportionof the operative temperature is primarilyradiation and is less effected by theopening of doors and windows.

The way convection/radiation occurswith radiators and floor heatingrespectively can be seen in Figure A.

As can be seen, with radiator systemsthe air temperature or convection makesup approximately 70% of the operativetemperature. This is also logical if youthink about how a radiator has quite a

small surface from which to transfer heatto the whole room. Conversely, floorheating supplies heat through a very largesurface evenly distributed in the room,which means that the ratio is just thereverse with 70 % of the operativetemperature being added by radiation.

Floor temperatureThe temperature of the floor surface mustbe sufficient to provide the required heattransfer into the space, but not be so highas to cause discomfort to occupants.Generally in areas where occupants areseated there should be a maximum of 9°C between floor surface temperatureand room temperature. This equates to a maximum surface temperature of 29°C in normal occupied areas and 33°C in changing/shower areas with a room temperature of 24°C.

In areas where people would notnormally be seated such as atria/foyers or areas with high glazing levels, themaximum floor surface temperature can be increased to 15°C above roomconditions.

Occupant comfortIn practice, it is not possible to maintainthe same temperature everywhere in aroom. It is recommended that a differenceof approximately 2°C between floor andhead height should be maintained. This isbecause most people want to have warmfeet while keeping “a cool head”. But thedifference in temperature should notexceed about 3°C as the body will become“confused” and comfort is reduced.

Characteristics and key elementsThe rate of heat output from underfloorheating is determined by the followingfactors:• Mean water temperature circulating

through the floor piping;• Temperature of the space;• Spacing and diameter of pipework;• Thermal resistance of floor coverings;• Thermal resistance of insulation/

flooring under the pipework.The mean water temperature and

pipework spacing can be varied to providethe required design output. This can beused to overcome issues such as highheat loss, floor covering with high thermalresistance or restricted emitter area.

The heat output is a function of thesurface area and the mean water

temperature. Given that the size of thefloor area, is so large the mean watertemperature can be much lower than thatcommonly-used in radiators while stillproviding the same output.

The following describes the majorelements of underfloor heating systems:

Energy source Underfloor heating can utilise a widerange of energy sources. Unlikeconventional heating systems that requirehot water at temperatures up to 80°C,underfloor heating is effective at flowtemperatures of 45°C. It is particularlysuited to condensing boilers due to thelow return water temperatures. The boilershould be fully condensing under alloperating conditions, with the exception of when domestic hot water generation is required.

Some of the sources of providing lowgrade heat and low carbon emissions thatare suited to underfloor heating includecondensing boilers; biomass boilers;various forms of heat pumps and solarpanels.

Heat pumps can take various forms, of which the most common types are,ground-source, water-source and air-source heat pumps. These typically have a Coefficient of Performance (CoP) of 3.5 to 4.0.

Solar panels may also be used as themain heat source, but they are be unlikelyto be cost effective. They can, however,be used in conjunction with a conventionalheating system or heat pump with the aimof reducing the load imposed on the mainheat generator.

Circulation pumpsIdeally, a single pump should be used to circulate water to the manifolds andthrough the pipework, though somesystems may incorporate a secondarypump and mixing valve attached to themanifold. Pump energy consumptionshould be minimised by avoidingexcessive pressure drops in thedistribution system and employingvariable speed pumps.

All pumps selected must comply withthe European ErP Directive EC 641 forglandless pumps, which comes into effect in 2013.

ManifoldsThe manifolds take the low temperaturehot water from the heat source anddistribute it through the underfloor heatingcircuits. There are separate manifolds forboth supply and return and theyincorporate electric control valves andbalancing valves.

Depending on the size of the projectand the number of circuits, it is notuncommon to have a number of manifoldslocated throughout the building.

Underfloor heating pipeThere are generally three main types ofmaterial associated with underfloorheating:(1) Cross-linked high density polyethylene

(PE-X) to BS EN 15875-2 : 2003;(2) Polybutylene (PB) to BS EN ISO

15876-2 : 2003;(3) Aluminium/plastic multilayer composite

pipe to DIN 4726 : 2000.All plastic heating pipes should

incorporate an oxygen barrier, and in thecase of composite pipes, an aluminiumfoil incorporated into the pipe provides theoxygen barrier.

Generally, two pipe sizes are availablefor underfloor heating, and these can varyslightly depending on the manufacturer,but are commonly 16mm and 21mm indiameter. Increasing the diameter willreduce the flow velocity and pressuredrop but also influence the heat output per unit area of the floor (assuming thespacing remains the same).

Insulation Insulation is a key factor in maximising theoutput of underfloor heating and particular

attention should be applied to thiselement. BS EN 1264 Part 4 states thatthe maximum limit to the downward heatloss should not be more than 10% of theheat supplied. This applies even to wherethe underfloor heating system is installedabove another occupied space (seeFigure B).

It is very important to provide edgeinsulation around the floor perimeterwhere underfloor heating is installed asthis prevents thermal bridging. Edgeinsulation also allows expansion of thefloor slab. Factors to be considered whenselecting insulation include compressionstrength, thermal conductivity andmoisture resistance. This should bediscussed between the building servicesengineer, the structural engineer and the architect.

System designThe design of an underfloor heatingsystem is no different to any conventionalheating design in that the designer mustagree the scope of design. All thenecessary information on the designrequirements has to be gathered from theclient/architect etc, and this information is generally greater than with traditionalsystems, as details of the floor make-upand floor covering need to be considered in the design.

All underfloor heating systems shouldbe designed in conjunction with BS EN1264 parts 1 to 5, as well as otherindustry norms including, but not limited to, Irish building regulations and CIBSEguides.

The required surface temperature, andconsequently heat output, are achieved

by varying the pipe spacing, circulationrates and flow temperature. The depth ofthe pipe and the thermal response of thestructure and covering are usuallydictated by other factors.

To achieve the required heat output foreach individual area, designers willgenerally base the required pipe spacingon pre-determined required flow and returnwater temperatures. Flow temperatures of 45°C and return temperatures of 35°Care commonly used.

Depending on the area in whichunderfloor heating is to be installed, thespacing requirements can take twoapproaches. The spacing can be installedto match the required heat output or thepipe can be spaced closer together toincrease comfort and/or response time.The latter approach may be beneficial ifthe floor coverings are unknown orundecided. Obliviously, the closer the pipespacing the more material will be requiredand hence there will be an increase incapital cost.

The manufacturers of underfloorheating pipework produce a range oftables that cover the selection of pipeworkand required spacing to achieve thedesired output.

Generally in commercial installationsthe underfloor heating circuit is arrangedas a secondary circuit from a primaryheader. The primary header usually feeds various circuits such as AHU’s,radiators and a calorifier, as illustrated in Figure C.

There is an inherent disadvantage withusing this arrangement with underfloorheating in that the boiler flow temperatureis matched to the highest requirement,which is usually the AHU’s or calorifier. Itmay be beneficial to consider separatingthe lower temperature underfloor heatingloads by the use of condensing boilers orheat pumps dedicated to the underfloorheating load.

Installation issues The layout of the pipework is also vital to ensure a cost-effective and efficientdesign. Too many manifolds can increasethe capital cost of the installation, and toofew can lead to pipework congestion, localoverheating and reduced control.

Generally as a guide the length of apipework circuit should not be more than

110 metres. Attention to the location of the manifolds needs to be considered, as particular areas of concern are wherepipes travel through a corridor to anumber of heated zones. This can lead topipework congestion resulting inuncontrolled and local overheating.

It is also important to consult with thestructural engineer with regard to locationof all expansion joints. If underfloorheating pipes pass through an expansionjoint in a structural slab, then these pipesmust be sleeved at least 200mm eitherside of the expansion joint.

Unlike with conventional heatingsystems, an underfloor heating specialistis generally employed to install andcommission the heating system. Thisspecialist is generally a sub-contractor of the mechanical contractor.

One of the key areas during installationthat needs to be strictly enforced, and isnot always complied with, is thequarantine of the work areas during thepipe-laying and covering. This is a vitalarea of concern that can sometimes beoverlooked and needs close co-ordinationwith the project schedule, main contractorand associated sub-contractors. Damageto the underfloor system from personnelor equipment can easily occur where pipes are left exposed.

ControlsThere are many ways of controllingunderfloor heating systems, from small-scale residential to large commercialbuilding management systems. However,the basic components remain the same.

The following components are commonlyused – electronic room temperaturesensors for each zone; outsidetemperature sensor; electronic mixingvalves; two-port zone valves; and mastercontroller.

It is highly recommended that aweather-compensator be incorporatedinto the underfloor heating design. Thisraises the floor temperature as the outsideair temperature gets colder. This will bebeneficial in terms of comfort and alsoenergy efficiency.

CostsThere is a preconception that underfloor heating is inevitably moreexpensive to install than conventionalheating systems. This is not always thecase and projects involving over 300sq m of underfloor heating can be cheaper in “install costs” to acomparable conventional heating system.As with all projects, an accurate costcomparison should be conducted whichtakes account of the whole life costs ofthe system.

The running costs of underfloor heatingcan also be very beneficial since, as we discussed earlier, the room airtemperature can be reduced byapproximately 2°C. This translates into a significant reduction in building heatlosses and energy consumption. The typeand height of a zone also has big impacton the running cost – rooms with highceiling or atria can see significantreductions in energy consumption whereunderfloor heatin is incorporated. ■12

Hitachi’s Yutaki heat pumps produce sanitary hot water andheating like any oil or gas boiler but does so by transformingrenewable energy from the air outside into heat. Every 1kW ofelectricity used to power the heat pump can provide up to 5kW of energy for heating; this can reduce heating bills by up to 60%and cut CO2 emissions by 50% compared to traditional boiler-led systems.

The extra innovation in the Yutaki-S80 is that it has twocompressors, working in a smart cascade system, with tworefrigerant cycles – R410a and R134a. To maximise seasonalefficiency, the second refrigerant cycle is only operated as abooster, when very high water temperature is required. Only onecycle is used the rest of the time.

The Yutaki-S80 is ideal for existing properties, in particular olderestablishments where higher water supply temperatures may berequired to keep the house warm. It is designed for boilersubstitution, offering heating and sanitary hot water all year round,without boiler back-up. That said, it is also suitable for new builds.

The Yutaki-S80 is easy to install and operate. It is a split system,using Hitachi’s IVX outdoor unit with a brand new stand-aloneindoor unit, which is designed and manufactured in Hitachi’spurpose-built factory in Spain.

Six different models, covering a range from 10kW to 16kW, areavailable in single phase or three phase versions. The indoor unitis a standard width of 600mm, allowing seamless integration intokitchens and utility rooms. It also includes a 200-litre or 260-litreSHW tank.

The system is simple to control. Its wireless remote controller is a variation of the well-received and successful design used with the existing Yutaki-S system, which includes a helpful LCDgraphic display, one-touch holiday button, weekly timer and frost protection.

Fergus Daly, Area Sales Manager Ireland, Hitachi AirConditioning Europe SAS, said: “The Yutaki range is at theforefront of technology in domestic heating and Hitachi is delightedto bring the Yutaki-S80 to its customers, with its impressive arrayof energy-efficient benefits.”

Other models in the Yutaki-S split system range – all of whichinclude auxiliary heating as standard, – are available with up to 60°C leaving-water temperature and in capacities from 5.1kW to 24.0kW. This energy efficient range is Eurovent and NF PACcertified and the 5.1kW model has a market-leading COP of 5.Hitachi also manufactures a range of Yutaki-M Monobloc heatpumps with outputs from 5kW to 17kW all with MicrogenerationCertification Scheme approval and NF PAC certification. TheYutaki-M won Hitachi the “Heating Manufacturer of the Year” title at the InstallerLive Awards UK 2011, for its energy efficiencyand innovation.

All of the Yutaki range can be connected to underfloor heating, convectors, radiators and domestic hot water tanks.

At the end of 2012 Hitachi will introduce the KNX Gateway,allowing the full Yutaki range to be controlled by a BMS system.The Yutampo is another heat pump in Hitachi’s range that can be installed independently of Yutaki-M or S. It comprises a single-split heat pump outdoor unit and an indoor, 262-litrestainless steel tank. The outdoor unit is equipped with a DCinverter compressor and facilitates a service water temperature of up to 65°C (with activated electric heating).

Training and support for all these systems is available forinstallers at Hitachi Aircademy centres across Europe and throughits large distribution network.

“Plenty has been said of the need for Ireland to follow mainlandEurope’s lead when it comes to the provision of heating and hotwater technologies. Underfloor heating (UFH) is one suchinnovation which has been adopted on a large scale by ourcontinental counterparts, which suggests there is a real opportunityfor us to change our attitudes towards this technology in Ireland.While the market for UFH remains healthy, rarely is it consideredstandard practice for architects, specifiers or installers, which issomething we need to change in order to work towards achievingour environmental targets.

“The technology itself is fairly simple. Heated floors act as low-level radiators, distributing heat evenly into each room andgradually warming the living space through a combination ofradiant energy and heat conduction. In a modern, well-insulatedhome where heat loss factors have been taken into account, UFHcan act as the primary heat source, eliminating the need forradiators and allowing more open space and fewer restrictionswithin a room.

“What is also worth highlighting at this point is that there is nominimum requirement for the technology, which can be installedacross a whole property or in an individual room, depending onrequirements. Pump mixing stations can also be provided to caterfor outputs of up to 25kW.

Sustainable solution“In general, UFH can be more efficient than traditional radiators fora number of reasons, as well as practically liberating a room so asto be able to site furniture and furnishings wherever you want.

“Despite the simple nature of underfloor heating as a concept, the technology also has sustainability credentials. While radiatorsgenerally require water to be heated to a temperature of around

75-80°C, an UFH system typically requires water heated to between 40°C and 50°C. Because of the requirement for lower output from the primary heat source, renewable technologies such as ground or air source heat pumps are well-suited to being used in conjunction with UFH as they operate efficiently at low flow temperatures.

“As we receive more information on the level of incentives onoffer for those who opt to have these technologies installed, weexpect interest in these technologies to grow, which is likely to seemore installers increase their awareness of the complete systemsolutions available through manufacturers such as Worcester.

“A ground or air source heat pump in particular uses compressortechnology to give very high efficiencies in supplying heated waterto a connected property – a method which is ideal for lowtemperature ‘trickle’ heating emitters such as underfloor.

“The versatility and operating temperatures of UFH as apractical heating alternative also lends itself to condensing boilers,which now probably account for the biggest number ofinstallations. It is estimated that the system will operate atefficiency levels of at least 5% higher than higher-temperaturesystems such as radiators.

“Heated water is circulated through continuous runs ofpolybutylene pipes which are embedded into the screed of theproperty. In the past, the complex routing of the pipework had been an issue for installers. However, most market leaders arenow providing a ready-made routing infrastructure as part of asupplied package.

“This pipework is connected to a manifold which shouldincorporate a flow meter as standard. Once subsequentconnection to a pump station is achieved, the temperature of thecirculated water can be constantly regulated.

“Crucially, UFH is suitable for both new-build and existingproperties as solutions can be tailored for both solid/screededfloors and timber/suspended floors. A number of different controlspackages are also available, including wireless and 230V controls and recessed and surface mounted manifold cabinets.Worcester’s dedicated heating design department is on hand toproduce a specification, material lists and detailed pipe layoutdrawings for individual projects in the event that the installerrequires assistance.”

For an underfloor heating system to work efficientlyand problem-free, all the components need to be compatible.Many quality issues have arisen in the past because ofincorrect combinations of components, often purchased from different manufacturers.

It is for this reason that Myson devised the “completesystem assurance” concept which promotes the advantagesof using tried-and-tested component compatibility. Through acombination of in-house design and planning, followed bythe installation of coordinated Myson components, Mysoncan assure customers of efficient system performance.

“The complete system guarantee provides added value tothe installer and gives the consumer peace of mind”, saysVincent Broderick of Potterton Myson. “Using a system withcomponents designed and built to be compatible with oneanother is essential for the correct installation and running of

an underfloor system. A mix-and-match system is invariablygoing to lead to problems, particularly when compared withthe Myson range which has been designed to fit together.Long term, it pays to rely on completely compatible systemsfrom Myson instead of the tedious and risky self-assembly of mix-and-match alternatives”, concludes Vincent.Contact: Potterton Myson Ireland. Tel: 01 – 459 0870;email:[email protected] �

Seven reasons to choose Myson 1. Myson is a bespoke underfloor heating system provided

with a complete system guarantee;

2. The system is tried and tested and, as part of the Rettig

Heating Group, is the largest underfloor heating company

in Europe;

3. Myson’s quality can be relied upon, unlike systems made

up of individual, incompatible components;

4. The installation is guided by Myson’s project-specific

system drawings;

5. The manifold comes in a chrome finish with branded

actuators that can easily fit into most modern homes.

The blending valve is also situated here and can be easily

changed to suit the required flow temperature, which helps

to economise;

6. The Myson MF takes minimal time to assemble. It is

supplied almost complete – all that is required is the

connection of the pump/blending valve into the side of

MF frame. There is no need for bends, tees or time-

consuming plumbing;

7. The thermostats are Myson branded and best suited to the

system. The MPRT programmable stat has three different

temperature settings, and these can be used 24/7 to make

sure the required heat is available at all times.


‘Installers get more from Myson’

When it comes to underfloor heating, Potterton Myson Ireland works hard to make life as easy as possible for installers. As an additional benefit, thecompany also has an assurance package that gives both the installer andhomeowner peace of mind.

Toshiba heat pump on coursefor two year payback

The house in Enfield, Co Meathwas heated with LPG whichO’Donoghue found too

expensive to operate. “When Feargalresearched a suitable heat source forhis renovated home he was influencedby the Toshiba Estia and paticularly theunrivalled efficiencies Estia offerscompared to the competition,” saidDerek Phelan of Toshiba suppliers GT Phelan.

O’Donoghue – whowas looking for aheat pump to meethis space heatingneeds but wasn’tconcerned with hotwater – waited untilEstia was launchedin Ireland in 2010before makingenquiries to GTPhelan, Toshiba'ssole Irish distributor.The company, basedin Bray, Co Wicklow,assisted him withproduct selection,and suggested anapproved installer toengineer a solutionfor the project.

Underfloor loopswere installedthroughout theground floor, with lowtemperature radiatorsproviding heating toupstairs bedrooms.

No additionalenergy savingmeasures wereapplied to thebuilding.

When Estia was

installed it was configured to operate in conjunction with the existing boiler, to allow the boiler to provide heatwhenever external air temperatures fall below -50C. The Toshiba systemwas also fitted with an energy metre,allowing Feargal to monitor the power consumed.

The final bill for installing the Toshibaair-to-water system amounted toe7,000, minus a e2,000 grant. Thetotal fuel burn using LPG (January toDecember 2010) amounted to e4,200while the total electricity bill (January toDecember 2011) amounted to e1,380 –a reduction of over e2,800,representing a two-year payback.

O’Donoghue is clearly impressed.“The Toshiba air-to-water system issimple to operate and has reduced my energy bills by approximately 60%,”he said.

The Estia model HWS1403 producesup to 14kW heat and operates with aCOP of 4.50 at an air temperature of70C and a water supply temperature of350C, with a maximum power input of 4kW.

GT Phelan has a long track record ofenvironmental stewardship stretchingback over 20 years. Company directorDerek Phelan introduced a system forthe safe disposal of refrigerant gases in 1992, a system which the companysubsequently rolled out across allinstallers.

“At GT Phelan we’re genuinelycommitted to reducing carbonemissions, and to keeping our impacton the environment to a minimum,”Phelan said.

The European Union estimates that there are circa 85million large electrical motors at work in the community, using 70% of the energy used by industry.

It was therefore inevitable that electric motors would become partof strict new regulations which are forcing industrial users, includingthose involved in water-related applications such as wastewaterpumping, to become more efficient.

Already in place is the IE2 standards, which demand that allsingle–speed, three-phase induction motors with output ratings from0.75–375kW sold in the EU need to achieve as a minimum the IE2efficiency level.

However, the European Union has notstopped there. Due out in 2015, but alreadyfocusing the minds and resources of pumpmanufacturers, is the new IE3 PremiumEfficiency standard, a new efficiency classin Europe which is identical to the USANEMA Premium class for 60Hz motors.What’s more, the European Union alsoplans to upgrade the standard further withthe introduction of an IE4 standard on adate yet to be specified.

Pump manufacturers have thereforebeen concentrating on IE3, while keepingone eye on IE4. IE3 mandates that allindustrial motors between 7.5kW to 375kWmust either meet the higher IE3 premiumefficiency rating or at least meet the IE2rating and be equipped with a variablespeed drive.

For motor users in the water industry, particularly those inwastewater applications, the potential for energy savings is clear.For a 1kW motor, roughly 8% of its input energy is saved by going from IE1 to IE2. By converting from IE1 to IE3 around 11% is saved.

Pump manufacturers have, as a result, been investing heavily inR&D in order to produce pumps capable of not only attaining IE3but also giving them a head start when IE4 comes around.

One of the ways of meeting, and even exceeding, the newregulations is to use a line started permanent magnet (LSPM)motor. The first big advantage of an LSPM motor is that the motoritself can be made significantly smaller while generating the sameamount of power. In turn the smaller size of an LSPM motor meansthat this type of motor is inherently more sustainable than inductionmotors due to the fact that they use less iron and copper.

The second big advantage of an LSPM motor, such as the type used in Flygt Experior, is that this type of pump is capable ofgenerating significant efficiencies. For example, Flygt Experior iscapable of up to 4% higher efficiency than the current IE3 standard.

Additional energy saving benefits are also available. LSPMmotors used for variable frequency duties are capable of highsustained efficiency at lower speeds with circa 3% additional energysavings the norm in comparison to an induction motor.

What’s more, there are ancillary benefits which can furtherreduce cost. Lower bearing temperature can prolong motor andbearing lifespan and an LSPM motor also enables the use ofsmaller breakers and reduced cable dimensions. This means thatthe replacement of the control panel is not required which can makea significant contribution to cost reduction when upgrading apumping station.

However, it would be wrong for pump users to merely identify themotor as a target for energy efficiency measures. While the motorcan deliver efficiency in line with IE3, many pump users in the waterindustry are under pressure to find other ways of reducing costs.Fortunately, beyond the motor and drive, there are various ways inwhich “intelligence”, through monitoring and control, can be used todeliver big savings in energy usage.

It is not uncommon to experience pump clogging orsedimentation in the pipes. Often this is due to the fact that theparameters in the VFD have not been set in a correct way.Parameters are hard to set and require the skills of a trainedengineer to ensure that the VFD is suited to wastewater pumping.

The answer might lie with intelligent pump control functions likeFlygt SmartRun which is a unique software for wastewaterapplications – a “plug and play” product with the ability to reduceenergy consumption in a pumping station by up to 30% comparedto conventional on/off control.

The software works by securing the speed of the pump to itsoptimal energy level without the use of a flow meter or any otherexternal measurement equipment. In combination with an LSPMmotor there is the possibility for even further savings derived fromthe ability to maintain motor efficiency at lower speeds compared topremium motors of a conventional design.

The tightening regulatory environment is setting a high bar forpump users to get over, but new technologies such as LSPMmotors and intelligent pump control can help end users both adhere to the new regulations and save money.

The NSAI is soon to publish anIrish Standards Recommendation,SR 50, which will be a BuildingServices Code of Practice (COP) for the heating and plumbing trade.The COP will initially have threeparts – SR 50-1: Domestic plumbingfor hot water and heating; SR 50-2:Thermal solar systems; SR 50-3:Domestic plumbing for cold watersystems.

The function of the SR 50 heatingand plumbing documents is to layout a Code of Practice for plumbingworks carried out on domesticdwellings using solid fuel, gas, oiland other fuels for heating. It isenvisaged that the SR 50documents may be used as part ofan industry training course in thefuture with a regulatory regime notunlike the Registered Gas Installer(RGI) scheme in effect since June2009. The SR 50 documents areaimed not only at trainee plumbersand heating installers but also at themature craftsmen who may obtainnew knowledge on their craft.

The committee and its projectsare being project managed byFergal Finn. Each part of SR 50 willbe published when all the publicenquiry comments have beenaddressed. NSAI plans to publish

SR 50-2 in September 2012 withthis part laying out the requirementsfor installing solar thermal systemsin domestic dwellings. Due to theextensive scope of the domesticplumbing for water systems andheating, it is expected that the hotwater systems and heating, SR 50-1,will be published by the end of theyear and the cold water SR 50-3 tofollow in 2013.

In addition to the work beingcarried out by the Building ServicesCommittee, the NSAI Gas TechnicalStandards Committee (GTSC) is inthe final stages of preparing therevised public comment draft of the Irish Standard for domestic gasinstallations, IS 813. A draft shouldbe expected for public comment in September 2012.

It is worth noting that the workcarried out in the development ofIrish Standards is done by NSAItechnical committees made up ofindustry experts who freelyvolunteer their time on behalf oftheir companies, associations andorganisations for the benefit of theindustry. NSAI would like to take this opportunity to acknowledgethose industry experts whocontribute to the development ofIrish Standards. �

Prompted by members to organise more social occasions – as opposed to thetechnical, conference and seminar programmes – CIBSE Republic of Ireland Regionheld a BBQ in Dicey Reilley’s in Harcourt St, Dublin 2, during the last week in July.

People started to arrive from 6.30pm onwards and food was still being served up aslate as 8.30pm.

For a first-time event it proved very successful. The food and craic was excellent,while the older members in attendance gradually became accustomed to the freneticbuzz and loud music.

The sensible among us started to drift homewards at about 10.30pm while theyounger contingent – and braver older contingent – stayed on with the intention ofdrifting up the road to “Coppers”. What transpired after that remains “on tour!” ■

Panasonic Aquarea 3kW and 5kWperfect solution for low energy homes

Vincent Mahony, Ireland Country Managerfor Panasonic Heating and Cooling,said: “These new Aquarea 3kW and

5kW models offer amazing energy savings. In fact, the Aquarea 3.2kW model achieves a COP (coefficient of performance) of 5 attemperatures of 7oC. It is also capable ofmaintaining capacity and efficiency at outdoortemperatures as low as -20oC.

With a compact design, the units are small,making them perfect for social housing, smallhomes and apartments. The units are alsosuitable for balconies and ground floor, gardenflats. They address the requirement for energy-efficient units for homes with a low heatingdemand and, in doing so, are much moreflexible and cost-effective than a traditionalfossil fuel boiler.”

Super-efficientThanks to the system's high degree oftechnology and advanced control, the Aquareaheat pump is capable of maintaining a highcapacity and efficiency, even at outdoortemperatures as low as -20oC. To furtherimprove the system’s energy efficiency, thenew Aquarea units feature an A-class pumpwith three different speeds to adjust to therequired water flow.

Panasonic's software has been adapted tothe requirements of low consumption homes in order to optimise the unit's energyconsumption, which ensures that whatever theweather, Aquarea will always deliver maximumefficiency. In combination with the newPanasonic HR200 sanitary hot water tank, the3kW and 5kW units deliver hot water at atemperature of up to 55oC, even at outsidetemperatures as low as -15oC.

The HR200 tank is specially designed for

connection to heat pumps, features a 1.8m²surface, and is extremely efficient. It thereforeensures that hot water production is conductedin the most energy efficient way.

These Aquarea units are single-phase andbi-bloc, separate indoor and outdoor units. The outdoor units are super-quiet and have a rating of only 47/48dB – ideal for installationin apartment blocks and high-density living where quiet units are required to avoidupsetting neighbours.

Simple controlBoth Aquarea models offer optimum control,thanks to a room temperature thermostat andbuilt-in management of the hot water cylinderand heating. Panasonic has also added theinnovative IntesisHome smartphone control,designed by Intesis Software, to the Aquarearange. By downloading the app home ownerscan control their heating and cooling via amobile. Both iPhone and Android versions are available.

These new models fully satisfy all relevantEuropean regulations, including the new RT2012 (Règlementation Thermique 2012), the very high standard for thermal performancein France. Both models also use theenvironmentally-friendly refrigerant gas R410A.

Eco-Design Directive

2013

Daikin

Today


Seasonal efficiency is a more accuraterepresentation of actual system performance … – Where efficiency was previously measured at a single

outdoor temperature (35°C for cooling, 7°C for heating),seasonal efficiency uses a range of outdoor temperaturesthat more accurately reflect actual performance over anentire season;

– Where efficiency was previously measured with systemsrunning at full capacity (most systems seldom operate at fullcapacity), seasonal efficiency emphasises the more realisticpartial load efficiency;

– Where efficiency measurements previously ignored auxiliarymodes such as standby, seasonal efficiency includes thesignificant levels of energy consumption that take placewhile the system is “off”.

Seasonal efficiency measurements on air conditioningsystems thus reward designs that optimise overall energy useover an entire season under real-life conditions.

Daikin continues to rise to the challengeWhile the legislation mandating the seasonal efficiencystandard for comfort cooling systems under 12kW will onlycome into effect in 2013, Daikin Europe NV has already takenpioneering steps towards its implementation.

In addition to providing industry-relevant input to thelegislators drafting the standard, Daikin was the first to publishseason performance figures for its residential and commercialair conditioners, and the first (in 2010) to integrate Eco-designprinciples (designing for seasonal efficiency) in its Sky AirSeasonal Inverter line for light commercial use.

In line with its leadership role in seasonal efficiency, Daikin isproud to announce a further expansion of the Sky Air seasonalefficiency portfolio. The improved seasonal efficiency of thenew Sky Air units results in substantial energy savings forshops, restaurants, offices and small hotels.

Sky Air seasonal efficiency portfolioThe Sky Air seasonal efficiency lines offer two paths toseasonal efficiency — the RZOG-L Seasonal Smart for topseasonal efficiency, and the RZOSG-L Seasonal Classic forapplications requiring less flexibility. Both lines of outdoor unitsoffer improvements of more than 40% (*FCQHG100F +RZQG100L7V1 SEER values compared with previousFCQH100D + RZQ100D9V1) with respect to present Sky Air systems.

The full range of indoor units supported by both systemsmakes either solution a logical choice for small businessowners concerned about economy and ecology. The newFCQG & FCQHG round flow cassette is setting the standardfor comfort and efficiency. It boasts 360° air distribution andoptional room and floor sensors, depending on the currentroom temperature, occupation levels, and even the location ofpeople in the room.

The FBQ-C8, FDQ-C, FDQ-B concealed ceiling units featurean inverter-driven fan for maximum partial load efficiency, anenhanced controller for optimum, efficient system control, andwhisper-quiet operation. Completing the line-up is the equallyredesigned FVQ floor-standing unit, as well as the new FAQwall-mounted unit, both with a new casing.

The FFQ 600x600 4-way blow cassette and FHQG ceilingsuspended cassette have been redesigned to be able todeliver high seasonal efficiency values. Thus there is a Daikinseasonal efficiency solution for a range of light commercialapplications, and for a range of budgets.

The Sky Air seasonal efficiency portfolio is just one morereflection of Daikin Europe NV’s continuous concern for ever-more efficient, cost-effective and environmentally friendlybuilding comfort solutions.

Environmental issues such as global warming and decreasing stocks of fossilfuels have resulted in the need for more efficient climate control systems. This hasbeen expressed in aggressive European environmental targets to be met by theyear 2020, commonly referred to as the 20-20-20 targets. To effectively realise these targets, Europe has also mandated more realistic measurements of actual system efficiency: so called seasonal efficiency.

Daikin leads the way in seasonal efficiency

Generally mechanical work is nottoo dissimilar to what we do inIreland, but the electrical codes doseem to be from a distant planet.I’m also getting my head aroundthe fire codes that at times seemcounter-intuitive. Everything here is sprinklered, including swimmingpools and ice rinks, and as aconsequence smoke detectors

are generally not required!Arup have been in the Americas

for the last 25 years and in Toronto since 2000. Our buildingengineering offering is less thantwo years old and marketing isobviously a big part of my job.There are definitely moreopportunities here than at home(not hard says you) with cranesdotted all over the skyline.However, breaking into the marketis tough, particularly for publicwork. Infrastructure Ontario controla huge amount of public workprojects and add layer upon layerof bureaucracy to the entireprocess, all in the interest of“fairness”. One word of caution inthe GTA is that while there are 180high rise projects on site or due tohit site in the next 12 months, the vast majority of these areresidential condos. Sound familiar?

The real boom in Canada is outin Alberta and is in support of theoil sands industry there. Canadiancontractors and consultants arerecruiting in Ireland to assist withworking on these projects. Beaware that the housing and socialinfrastructure to assist this boom is

Toronto Islands ferry.

lagging behind – this means plenty of construction jobs, butaccommodation can be veryexpensive, if it is available at all.Also, the oil extraction locations arepretty remote and will be hot hot hotin summer and icy-cold in winter.

The weather so far in Toronto by the way has been fantastic andit really helps with the outdoorlifestyle here. Let’s see what winterbrings. Below I’ve added a fewwatch-its if you are considering a move to Toronto or to Canada. In general:

Immigration Make sure you have a job offer andall your paperwork in place beforeyou arrive. Immigration is tight andwill have no hesitation in sendingyou home on the next availableflight if you arrive without it.

EngineerThe title of Engineer is highlyregulated in Canada and it is illegalto call oneself an engineer unlessyou have obtained the titleProfessional Engineer (P. Eng.)which is equivalent to CharteredEngineer status. While EngineersCanada were signatories to the

Washington Accord, it is theindividual provinces who areresponsible for the control ofprofessional titles.

There is a minimum 12-monthtraining period and exams to betaken before one is conferred witha P. Eng. A further difficulty is thatthe term Building ServicesEngineer is unknown in Canadaand degrees from abroad bearingthat title are not recognised, atleast not in Ontario, meaning thatup to 12 3-hour written exams mustbe taken, along with the associatedstudy time. We think we may havefound an easier route throughBritish Columbia but it will be a few months before we know theoutcome of same. Those with astraight mechanical or electricalengineering degree should have a more straightforward path toobtaining P. Eng.

Cost of LivingToronto is at least 15% moreexpensive than Dublin. Groceriesare generally less expensive, butdairy is expensive. Eating out isgenerally cheaper than home but beer and wine is much moreexpensive, particularly downtown.

HousingThere is a reasonable supply ofhousing available in the GTA but it can be expensive. The closer you get to downtown it is likely tobe an apartment in one of the new condominium towers.Those thinking of buying should beaware that mortgages are tightlyregulated. The max loan to valueallowable is 80% and max term is25 years. House prices have beenincreasing 8% to 10% annuallyover the last decade and there are some concerns regarding ahousing market bubble.

TransportationToronto has a pretty goodintegrated public transportationinfrastructure. There are two mainsubway lines running north/southand east/west, (soon to beextended). The bus service linkswell with the subway and trolleybuses, while novel, tend to be slow.The wider GTA area is served bythe Go suburban rail system.

Cars and petrol at $1.25 a litreare cheaper than home, but carinsurance is horrendouslyexpensive in Ontario and in theGTA in particular. That 10 years no claims bonus you carefullyminded in Ireland cuts no ice with the insurance companies here,but will at least allow you to get aquotation. Expect to pay at least$3000 for a standard family car.Also, while holders of British drivinglicences can swap theirs for aCanadian equivalent, Irish licenceholders must sit both a theory anddrivers test.

CreditNew immigrants to Canada will find it hard to obtain credit.Obtaining a Canadian credit card is not easy and expect to receive a very low limit initially. ■

Trolley buses, while novel, tend to be slow.26


House prices in Dublin appearto be stabilising and I can certainlysee more “Sold” signs whichhopefully will lead to increasedactivity in the repair andmaintenance element of your businesses.

The market has its challenges andit has never been more importantthan now to run an efficient and lean business.

The following 10 areas ensure thatyou will have solid foundations onwhich to build your business,

CashflowCash is king … need I saymore! Be organised, collectmonies due in an orderly andtimely fashion;

TaxYou need to understandwhat you are liable for … nosurprises will be welcomehere!;

Create proper contractI covered this point already –see bs news May/June 2012.Write it all down and getcustomer sign-off before youstart work;

Ensure you are insuredPublic liability insurance is

essential. You should alsoinclude contents insurance;

Health and SafetyYou can’t afford to ignore this. Thereare specialists out there who canhelp. Take their advice;

ITWhatever size your business is,evaluate your IT system to ensure it supports your business now, andwhat you plan into the future;

Bank ManagerKeep in regular contact. They areoften well connected and can offeraccess to advice on your business;

Resist taking on fixed costsStay flexible/lean;

First impressionsThey do count so be presentable,tidy and organised. It could makethe difference;

TestimonialsA happy customer is your bestadvert … don’t be afraid to ask ifyou can use them as a reference.

If you can run through the 10-pointchecklist above you will havecovered the key points. In doing so,there may even be a point 11.

Enthusiasm and Drive Look forward, not back. Dwelling onthe “what if’s?” and “might havebeens” is pointless. Make aconscious decision to influence yourfuture. The good old days are nowand tomorrow! ■

BREEAM is an internationallyrecognised measure of a building’ssustainability. Some 245,000 buildings have been BREEAM certified, with a further950,000 registered for certification. Whilemany of these are in the UK, increasingnumbers are now in more than 50 othercountries.

Highly flexible, the BREEAM standard canbe applied to a very wide range of buildingtypes and locations, with versions for newbuildings, existing buildings, refurbishmentprojects and large developments. Theseprojects are assessed, rated and certified on a scale of Pass, Good, Very Good, Excellentand Outstanding.

ImpartialThe BREEAM assessment process is basedon an international network of more than 2600fully-trained and licensed, independentBREEAM Assessors. This approach gives theadded assurance that BREEAM-ratedbuildings are genuinely as sustainable as theyclaim – and that the highest-scoring buildingsrepresent some of the best examples ofsustainable design and construction. Ratingsdetermined by the assessors are subject toquality assurance by BRE Global, whichmanages BREEAM.

The use of independent assessors reflectsthe impartial ethos of the BRE Group, whichcomprises BRE, BRE Global and FBEManagement. The Group is owned by BRETrust, a charitable company that aims toadvance knowledge, innovation andcommunication in all matters concerning thebuilt environment. This ownership structurehas enabled the Group to be held as a stand-alone asset, independent of specificcommercial interests.

Scientifically robustBRE has been at the forefront of scientificresearch and development in the builtenvironment sectors for more than 90 years,and in recent decades has taken a leadingrole in sustainability. This experience,expertise and ongoing research provides therobust science that underpins BREEAM and is key to its enduring success.

Introduced in 1990, BREEAM is now theworld’s longest-established and most widely-used environmental assessment method forbuildings. A tried and tested standard, it isnevertheless regularly updated in line withnew developments, evolving legislation,feedback from users, and consultations withprofessionals and experts around the industry.The current standard was launched in 2011and the next update is due in 2013.

HolisticThe BREEAM assessment encompassessustainability in its widest sense – not justenergy use and carbon emissions, but also a wide range of issues concerned with waterconsumption, health and wellbeing, pollution,transport, materials, waste, ecology andmanagement.

Issues covered in the area of health andwellbeing, for example, include microbialcontamination to ensure that building services are designed to reduce the risk of legionellosis in operation.

Driving sustainabilityThe aim of BREEAM is not only to recogniseand reward buildings with genuinelysustainable credentials, but also to improvesustainability in those buildings and in the builtenvironment as a whole. The targets set bythe BREEAM standard encourage and helpdevelopers and project teams to push beyondregulatory requirements for sustainability.

Since its launchin 1990, BREEAMhas becomeknown aroundthe world as amark of qualityfor sustainableconstruction.BREEAMInternational Key AccountManager, PaulineTzachrista,reviews some ofthe key elementsthat have madeBREEAM soinfluential, andexplains how tobecome involvedin the scheme.

BREEAM – quality mark forsustainable construction

BREEAM edit:Layout 1 15/08/2012 15:55 Page 1


Early engagement with BREEAM, sothat sustainability issues are consideredfrom the outset rather than “bolted on”later in the process, helps to ensure thatmaximum benefit is achieved at little orno extra cost. The early involvement ofthe BREEAM assessor, with his or herextensive knowledge and experience in gaining the best sustainabilityoutcomes, is similarly beneficial.

Market recognitionA BREEAM rating can make a buildingmore marketable, both to tenants andpurchasers because BREEAM isrecognised as a mark of quality forsustainable construction – and for itspotential for cutting operational costs.

BREEAM can be used anywhere inthe world. In Europe there is a schemespecifically for office, retail and industrialbuildings – BREEAM EuropeCommercial – and there are also agrowing number of country-specificBREEAM schemes operated byNational Scheme Operators (NSOs).

For buildings that fall outside thescope of the BREEAM EuropeCommercial scheme and NSO-operatedschemes, the International Bespoke

version of BREEAM can assess singledevelopments. Tailored to suit localcircumstances, it can be used at thedesign, construction, initial occupationand refurbishment stages of a building’s lifecycle.

Getting involvedMany building services engineers andbuilding professionals of all kinds arevariously involved in BREEAM. Forexample they can:– Attend awareness training courses to

extend their knowledge of built

environment sustainability;– Obtain professional qualifications,

for example becoming BREEAMAccredited Professionals (APs).BREEAM APs can have importantroles in projects seeking BREEAMratings or greater sustainability ingeneral;

– Become licensed BREEAMAssessors. This involves completinga three-day training course followedby an exam and a homework case-study exercise to be completed within three months. The resultingBREEAM International Licence alsoallows them to carry outassessments using the BREEAMEurope Commercial scheme.

– Initiate or participate in the processthat leads to their organisationbecoming a National SchemeOperator.

On that date Carrier, a young researchengineer just a year out of CornellUniversity, finalised the design tostabilise the humidity in the air so thedimensions of the paper at the Sackett& Wilhelms Lithography and PrintingCompany in Brooklyn, New York, would

remain constant throughout the printingprocess. Since then this innovation hasbeen applied to everything fromshopping malls to manufacturingfacilities, buses to businesses and

houses to hospitals – all looking toestablish a comfortable environment.

In the early 1900s, air conditioningwas primarily an industrial applicationthat enabled countless industries tothrive with candy-making companies,textile mills and theatres some of the

most enthusiastic early adopters. Overthe years, Carrier's innovations lookedto make possible what was previouslyimpossible. Today its focus remains true to its heritage as it continually

pushes the envelope to create energyefficient, environmentally responsibleproducts for both commercial andresidential applications in all areas ofthe world.

A leading engineer of his day, Carrierfiled more than 80 patents over thecourse of his career. To celebrate the110th milestone, the company hasestablished a new website,www.WillisCarrier.com, which isdedicated to its rich history. It containslittle-known vignettes about WillisCarrier's life and work. The companyalso published a specially-commissioned144-page, hardcover book, calledWeathermakers to the World, which isnow available on Amazon.com. Thischronicles the entrepreneurial spirit ofWillis Carrier and the robust history ofmodern air conditioning.

At 25 years old, Willis Carrier'sforesight forever changed the world andpaved the way for more than a centuryof once-impossible innovations. Hisgenius created an entire industryessential to global productivity andpersonal comfort.

Apart from the rest of the world,Carrier has always been to the forefront of the development of the airconditioning industry in Ireland, and is now represented by Core AirConditioning.

What started as an invention to control humidity in a New York

printing plant in 1902 has forever changed the way people around

the world live, work and play. Last 17 July marked the 110th

anniversary of the invention of modern air conditioning by Dr Willis

H Carrier (left), inventor and founder of Carrier, the world's leader in

high technology heating, air-conditioning and refrigeration.

Carrier celebrates 110 years of makingthe world a cool place to live

In this artist's conceptualisation, Willis Carrier starts theengine that will drive the world's first modern air-conditioningsystem in the summer of 1902. This illustration appeared inthe August 1954 edition of Steelways magazine which noted,thanks to Carrier, that "air conditioning spread through theindustry like a cool breeze."

back issuesRotary inreceivership As we went to press MichaelMcAteer of Grant Thornton wasappointed Receiver and Manager ofRotary M&E Services (Ireland) Ltd.

Alarms bells initially soundedback in May when Australian parentfirm Hastie Group enteredadministration. However, at the timePhil Laidlaw, Chief Executive Officerat Rotary UK and Ireland, said thesituation presented an opportunityfor Rotary UK and ROI to emerge as a separateindependent group.

The intention then was for a rapidsale of the Rotary UK and Irelandbusinesses as going concerns. MrLaidlaw was quoted as saying thatthe two stand-alone operations werenot in any form of insolvency andthat they would continue to beoperated under the control of the existing directorsand management team on a“business as usual” basis.

However, the situationdeteriorated since then and, with nofirm offer for the businesses, thereceiver was appointed on 27 Julylast. While creditors were aware ofthe difficulties, they were still takenby surprise at the suddenness ofthe announcement.
