‘Price-sensitive’ merelyeuphemism for give away

Building services has always been a price-sensitive sector. Irrespective of project scale –from the smallest domestic job to the largest

commercial/industrial scheme – price invariably dictateswho gets the work.

A mixture of too many suppliers and little or noregulation resulted in a wildly erratic marketplace where, in the immortal words of Oscar Wilde, everyone knows the price of everything and the value of nothing.

In times of recession this malaise affects all industrysectors but building services is unique in that, eventhrough the boom times of the last decade or so, price was still the deciding factor in who got what job.

Not surprisingly, when now faced with the greatestrecession ever to afflict the sector, we are plumbing (sic)new depths in so-called price-sensitivity.

Ironically, the broader market parameters have neverbeen more conducive to breaking this cycle. Clients and end-users are demanding value-for-money; theyunderstand and are willing to invest in life-cycle gains;regulatory controls are plentiful and enforceable; and thereare grant incentives to support quality-led, rather thanprice-led, practices.

There has never been a better time to consign price-leddecision-making to the bin in favour of a more sustainableway forward. �

OFTEC ‘Boiler Passport’and oil heating show Irish boiler manufacturers are now issuing a“Boiler Passport” with every boiler manufactured inIreland. The passport scheme is designed toprovide a means by which consumers will receive aproperly-installed and commissioned appliance thatmeets current Building Regulations.

David Blevings from OFTEC Ireland told bs news: “Incorrect installation and failure tocommission is frequently the cause of boiler failure.It is therefore proposed that any future warranty willbe conditional upon the correct installation of theboilers and the completion of a “Boiler Passport”.

Meanwhile, the OFTEC oil heating show will beheld at City West Hotel, County Dublin on 2October from 11.30am to 4pm. Products on displaywill include oil boilers, cookers and stoves, tanks,and ancillary equipment.

Following the show the 2009 OFTEC Awards forExcellence will take place, the first time this eventwill be held in Ireland.

Kevin has served on theBoard as a Non-Executive Directorsince 2002. Hechaired the Audit,Risk & FinanceCommittee of thePMH Board since2007 and wasalso the Senior

Independent Directorsince that date. Kevin isalso a Director of KerryGroup PLC, and Chairmanof Schroder Private EquityFund of Funds PLC, SVGInvestments Dublin PLC,and the National FolkTheatre of Ireland.

Welcoming hisappointment, PM GroupChief Executive PatMcGrath said: “Kevin’sprevious commercialexperience over manyyears of managing andleading large Irishorganisations along withhis “hands on” experienceof wide-rangingorganisational structures,has been of significantbenefit to PM Group asthe company has grown,both domestically andinternationally, in recentyears.”

Multifit GasSaver from PMI The Multifit GasSaver is an innovative product that sits neatly between a boiler andflue and recycles the heat from the flue gases which would normally be expelled intothe atmosphere and wasted. It has been proven by independent testing to achievedomestic hot water savings of up to 7%, and can reduce the gas used to heat hotwater by up to 50% annually.

The Multifit GasSaver stores the condensatenormally expelled into the atmosphere through theboiler flue. Heat from this condensate is thenrecycled to preheat water coming into the boilerfrom the cold mains supply, significantly reducingthe amount of gas required by the boiler to heat thewater. This means lower energy bills for the householder and greater carbon savings.

Key features and benefits are low carbon solution, offering up to 700kg carbonemissions saving; reduces cold water consumption by up to 37%; maintenance free;constructed from 316L stainless steel; no controls or settings; saves up to 50% ofthe gas used to heat hot water annually; simple to install; compatible with a widerange of Baxi Group appliances.

Prevent scalding with HoneywellFacilities managers should ensure employees and the public cannot be scaldedby hot water by fitting fail-safe thermostatic mixing valves (TMVs) on hot wateroutlets, says Honeywell.

TMVs are fitted in the hot and cold supplies to baths, showersand hand basins, to ensure a constant safe temperature at thepoint of delivery. In healthcare, thermostatic mixing valvescertified to Buildcert TMV3, such as Honeywell TM200VP, shouldalways be fitted. Valves to the domestic TMV2 standard, such asHoneywell TM300, are acceptable for most other premises but arisk assessment should be carried out to determine if the facilitiesare used by vulnerable people, such as the elderly, youngchildren, or the mentally or physically disabled. If so, TMV3valves should be installed.

Both Honeywell TMV models employ a highly-sensitive waxelement which controls the hot and cold water inlets to provide asafe uniform temperature between 38

oC and 46

oC.

Naturally ventilating abuilding actually offers thebest of both worlds,

combining little or no energyconsumption with low capital costs,while still providing adequate freshair and comfort temperatureconditions throughout the year.With plant room also eliminated, the space required for services

is minimised, leading to lowerservicing/maintenance costs.

Natural ventilation now makes forone the most practical choices ofthe day. Modern buildings – withtheir low u-values and high heatgains – typically have a high

cooling requirement. The climate in Ireland is perfectly suited fornatural ventilation applications withlow extremes of temperatureproviding an ample supply of freshcooling air, even in a typicalsummer.

6

Natural ventilation is both cost and environmentally effectiveNatural ventilation, unlike mechanical fan forced ventilation, simply uses the naturally-occurring pressure differential forces of air movement,wind and buoyancy to deliver a steady supply of fresh air for buildingventilation and space cooling. In an environment where energyconservation is at a premium this sounds ideal … and it is, says Jim King, Managing Director, Finheat Group.


NATURAL VENTILATION SYSTEMThe Complete Solution

Finheat Mistrale spread:Layout 1 21/09/2009 10:09 Page 1


7

Natural ventilation strategies arefounded on two basic operationalstrategies and essentially compriseeither wind-driven systems or abuoyancy (stack effect) system.The Gilberts Mistrale naturalventilation range embraces both of these concepts.

In some locations and buildingdesigns, wind alone can be usedas the principal driving force. Inwind-driven systems the air on the wind-ward side of the buildingcreates a positive pressure withcorresponding negative pressuregenerated on the leeward side.Using this effect air can be easilydrawn through the building.Although wind-driven systems can be effective, building design,orientation and location factors areimportant here for a successfulresult. While obviously helpful,natural ventilation systems do notneed wind to operate satisfactorily.

More effective strategies employalternative buoyancy and stackeffects to provide the ventilationbase. Instead of wind pressure, a vertical stack or shaft in thebuilding can be utilised to allowwarmer air to migrate and risethrough the building to high leveloutlets, while drawing fresh cool air in from low level.

Stack ventilation does not rely onthe wind at all and, because it doesnot rely on the pressure or directionof the wind either, offers greater reliability as well as more flexibilityon the placement and location ofthe air intakes.

“At Finheat”, says Jim King, “ourengineers have extensive

experience of Gilberts naturalventilation systems. They are on hand to discuss the mostappropriate strategy for eachindividual project. The solution maybe wind-driven, stack-driven or, for more challenging projects, amixed-mode system that includesmechanical ventilation.

“With carbon emissions andenergy reduction the critical factorsgoverning all aspects of buildingsservices, natural ventilation offers a solution that is both cost andenvironmentally effective.”

DC fan technology from Mark Eire (TAC)In theory, human thermal comfort exists when the rate of heat

production becomes equal to the rate of heat loss. Therefore,

the accurate control of temperature and relative humidity can

bring this about, with air playing a huge part in the even

distribution of temperature and control of relative humidity.

The cost of achieving the correct amount of air can be greatly

reduced with DC fan technology as opposed to commonly-used

AC technology. That is why Mark Eire uses DC fans

manufactured by PLC Ltd in its equipment.

Benefits include substantial energy savings; lower functioning

costs; perfect for integrating state-of-the-art technology; reduced

fine-tuning time; cheaper airflow

control components and power

components; easy and quick

diagnostics; accurate

foreseeable interventions that

can be planned; and tele-

maintenance via modem.

Phone booth or car boost?With mobile ‘phones making public telephone boothsredundant, Madrid has devised a novel use for theseunderutilised installations. Ideally located on the edge

of pavements and with their ownelectricity supply, they make perfectcharging stations for vehicles.

Apparently, they are relativelyeasy to adapt and already 30kiosks have been earmarked toform part of a test project that, ifsuccessful, will eventually lead to anetwork of state-subsidised vehiclere-charging points.

Barcelona and Seville are nowalso getting in on the act, thepreference in Barcelona being

for “intelligent lampposts”. Again these are already in-situ, obviously have electricity, and are located on the edge of footpaths.

According to Derek Phelanof GT Phelan, Toshiba is oneof the few ac manufacturs sofar to produce a single fanoutdoor unit with a capacityof 14kW. The reason?Toshiba uses a twin rotarycompressor which is suitablefor use on the triple-coilcondensers. Most othermanufacturers use scroll orrotary compressors, whichmakes it difficult to produce a lightweight outdoor unit torival that produced byToshiba.

When you compareweights, a twin fan outdoorunit can weigh as much as120kg while the Toshibamodel weights just 77kg.Also, the overall dimensionsof the single-fan outdoor unit(795H x 900W x 320D) makeit easier to handle on site,particularly when trying to lift it though a skylight or inother awkward situations.Another distinct advantage is that it can be positionedbehind a parapet on a roof,

therefore hiding it from view. Moreover, the twin rotary

compressor allows thesystem to respond to thesmallest of demands byvarying the compressorspeed to lower RPMs thanthose available from othercompressor types. Likewiseat higher speeds, the twinrotary allows the compressorto ramp up to higher speedswith a resultant higheroutput.

Twin rotary compressorsare also balanced, makingthem quieter in operationwith less vibration.

All Toshiba equipment is provided with acomprehensive 3-yearwarranty covering parts, with a labour allowance. The light commercial range(5kw to 16kW) is suitable for direct replacement ontoexisting R22 and R407cpipework.

Wireless heating controlsare quick and easy to install,with no control cables to run,no untidy wiring and nodamage to home decorations.But there are also many otherbenefits to wireless controls,in addition to the savings oninstallation costs.

A wireless thermostat orprogrammable thermostatcan be wall mounted or placedon a table top using the baseprovided. Many users like tohave their heating controls at hand, just as they do withtheir TV controls.

Wireless programmablecontrollers, such as theHoneywell CM900 with itslarge text display, can changethe room temperatureautomatically several timesduring the day to matchtemperatures with lifestyles.This enhances comfort andsaves energy. They alsoinclude other energy-savingfeatures such as OptimumStart, and are suited toradiator and underfloorheating.

Wireless control isespecially useful wheninstalling heating systems inlarge properties because iteliminates long cable runs. It can be especially usefulwith historical or listedbuildings where interiorbuilding features and décorneed to be preserved.

In older premises whichhave been extended, wirelesscontrols remove the need to

drill cable holes throughsubstantial stone walls –originally exterior walls –which would be difficult andtime-consuming. Unlike TVremote controls which use“line of sight” infra-redsignals, the signals used by Honeywell heating

controls travel easily betweenrooms and between buildinglevels.

CM Zone extends theprinciples of wireless controlto multi-zone heating

systems. It uses wirelesssignals from centralcontrollers to HR80UKwireless receiver/controllerson each radiator, whichrespond only to signals fortheir designated heatingzone. The radiators, in turn,transmit “demand” signalswirelessly to a controller nextto the boiler. This aggregatesdemand to minimise boilerfiring and so is good for fueleconomy while also helpingextend boiler life.

The wireless CM900programmable thermostatcan create a single heatingzone very easily bytransmitting to HoneywellHR80UK wireless controllerheads, fitted on each radiatoror underfloor heating valve in the zone. As such it is ideal for creating additionalheating zones up to adistance of 30 metres.

Where programmablecontrol is not necessary, the new Honeywell DT92Ewireless thermostat is acompact, attractive and easy-to-use alternative.

Still tied to wiredprogrammers because youthink wireless offers noadvantages or you don’t trust the technology?Honeywell says it is time to think otherwise.

Ken Browne, Tour &Andersson’s Senior Engineerin Ireland, discusses the needfor, the design and applicationof small terminal units.

A high level of controllabilityis achieved through a well-designed system that iscorrectly balanced and whereeach component deliversoptimum performance. In thisinstance control of the plant is simplified and both comfortand energy-use targets canbe met.

When deciding upon propercontrol, the complexity level

must first be considered interms of two fundamentallydifferent control principles.These are discontinuouscontrol and continuous, or modulating, control.

Tougher demands, as wellas a higher degree of controldifficulty, require control thatenables a varied outcome.

Modulating control utilisesindiscreet steps to make thecontrol continuous and moreaccurate.

Modulating control itself isa very broad term. It can beused to include rather simplemodes such as proportionalcontrol, eg thermostats, aswell as more complex controlmodes such as PID. The bestadvice to ensure against therisk of control failures is tokeep the design as simple as possible.

Having selected amodulating control method it is important to ensure thehydronic system is well-designed and well-balanced.

In order to achieve the

desired indoor climate at thelowest possible energy-use,all terminals need to bebalanced and controlledproperly. How this is achieveddepends on several factors,but mainly it depends on theplant’s prerequisites. Herethere are three importantissues to address – is on/off control sufficient or ismodulating required? If modulating control isrequired, is it necessary to

stabilise the differentialpressure? If so, where is this stabilised, at each branch or locally?

Regardless what solution is selected, measuring isneeded to obtain a fully-controllable hydronic system.This will enable theverification of the flow tocheck that the design flow is available at each terminal,to receive systemdocumentation, and toperform trouble-shootingwhenever necessary.

A complete controls packin four options – designedspecifically with theSustainable Energy Ireland(SEI) Home Energy Scheme(HES) grant criteria in mind –is now available fromPotterton Myson Ireland.Assembled to include allitems needed for the installerto meet the SEI’s requirementin the most efficient manner,two of the options offer theadditional advantage ofwireless controls.

Installers can now choosefrom – SEI One: Divertervalve option with hard wiringcontrols; SEI Two: Zone valveoption with hard wiringcontrols; SEI Three: Divertervalve option with wireless

controls; and SEI Four: Zonevalve option with wirelesscontrols.

“Myson is the only Irishmanufacturer of controlscurrently offeringcomprehensive controlspacks that make it easy for installers to take up thenew business opportunitypresented by the HES” saysVincent Broderick, SalesDirector, Potterton MysonIreland. “As manyhomeowners and landlordsmay not be aware of thedetails of the scheme, it is a good idea for installers tochat to customers about it.”

Being a national scheme,all homeowners of dwellingsbuilt before 2006 may apply.

Landlords and owners ofmultiple properties may alsoapply, as well asmanagement companiesconsidering an entire buildingupgrade. Grants may be madeavailable to homeowners whoinvest in energy efficiencyimprovement through setmeasures in severalcategories, of which heatingcontrols upgrade is just one.

Grants are fixed for eachmeasure/category and officialapproval must be in placebefore any materials arepurchased or measurescommenced. Reimbursementis paid after the measures arecompleted and the contractorhas been paid by thehomeowner. Other conditionsmay also apply.

Only installers registeredwith SEI can participate andcarry out works on thescheme. Once the works arecompleted, the installer mustprovide the homeowner witha detailed Invoice and receiptfor all works finished, with a

fully completed, signed anddated “Declaration of Works”form which must also besigned and dated by thehouseholder and left withthem.

While the level of fundingfor heating controls upgradeis e500, the minimum heatingcontrols upgrade which willqualify for a grant is twozones (space and water) with7-day programmer (time andtemperature) control andboiler interlock, time andtemperature control of electricimmersion heater, and eitherone more zone control orthree TRVs.

However, it must beremembered that there is also a category for highefficiency (greater than 90%)gas or oil fired boilers withheating controls upgrade, the level of funding for whichis e700. Potterton MysonIreland can help here also,having an extensive choice of A rated gas-fired boilers inits Potterton range that arefully compatible with the new control packs.

“We will shortly be offeringtraining on the Myson rangeof controls and the SEIcampaign, in addition to theexisting course on Pottertonhigh efficiency boilers”,advises Vincent Broderick.“These training sessions willbe available in the factory inLimerick, as well as in ourtraining centre in WhitestownBusiness Park in Tallght.

“Apart from the tradingdownturn itself, there is no denying that the greatest challenge facing airconditioning contractors at present isexposure to credit and actually gettingpaid”, says Domnick Ward of Crystal Air. “This situation is furthercompounded by the new GovernmentForm of Contract, and the absence of the type of ‘leverage’ certificationaffords electrical and sprinklercontractors.

“That said, our philosophy has always been to develop relationshipswith our clients based on trust andcommitment, and this has certainly stood to us in the current climate. As we go forward I regard this as essential if we are to consolidate and grow whenthe situation improves.

“Indeed, there are already tentativesigns of an improvement and the greenpolicies being vigorously pursued byGovernment offer many possibilities. As air conditioning contractors we areideally placed to advise and support botharchitects and consulting engineers inensuring compliance with the raft ofbuilding services-related legislation andregulations now being introduced.

“Take for instance R22 phase out.There is still a great deal of confusionwith regard to cut-off dates, clientobligations, contractor obligations anddesigner obligations; where can thewaste gas go? What about R22 drop-inreplacements? Will the existing pipework be adequate to run highersystem pressures?

“Then there is the question of F Gasregulation compliance. The companyregistration scheme will be implementedsoon but what about individualcertification? Will the C&G 2078 besufficient after 2011? How much willcompany or individual registration cost?

“As for the suggestion that CO2systems offer a viable alternative toHFC, how can we prove this if nostandard exists? There should be interimcertification using EN14511 and, workingwith SEI and DOEHLG, we coulddevelop an equal standard to JRA4050with high-temperature hot water andheating solutions down to -15ºC usingheat pumps. This would open grantfunding for domestic installations andobtain Part L compliance in certainapplications..

“Turning to BER certification, this isdefinitely a step in the right direction.However, it is essential that only thosegenuinely-qualified to do so areentrusted with the role of assessor.There are far too many ‘snake oil’ sellers proclaiming to understandSCOP/SEER/VRF/AHU/SFP and all the other acronyms who have never set foot on a building site, let alone be in a position to make recommendationson completion of a report.

“As the foregoing illustrates, there are currently a great many unansweredquestions and challenges facingIreland’s building services sector.However, because of their combinedexperience and knowledge base, airconditioning contractors are ideally

placed to help devise a route mapforward. That is not to suggest that theyhave all the answers, just that they canbe part of the solution.

“However, for this to come about allbuilding services professionals have tobe honest and realistic. Despite theground-breaking developments of thelast decade, the simple ‘cut and paste’mentality of recent years is no longerviable. There is no ‘one system fits all’solution … every project has to beassessed individually. Moreover, thisassessment process has to take place at the earliest possible opportunity, andinclude all the disciplines involved.

“In the meantime, and with so muchgoing on in relation to core buildingservices-related issues, it is incumbenton air conditioning contractors to go backto school, so to speak. We can’t assumethat we have all the answers when it ispatently obvious that we do not.

“Nonetheless, what we do have is the means by which to arrive at thecorrect answers. In the RefrigerationInstitute and Refrigeration Skillnets wehave the perfect forum for debate,discussion and the exchange of views,ideas and opinions. There is also anexcellent educational programme whichcan be availed of. I genuinely believethat if we maximise this resource we willposition air conditioning contractors atthe core of building services, viewed as an equal partner by architects andconsulting engineers, as well and thevarious representative associations and Government bodies.” �

Hitachi ARG IVX+ and S Series set new standards


Hitachi Europe has introduced two new significant additions to its air conditioning portfolio – the Hitachi ARG IVX+ Series and Hitachi RAS SX8 S Series.

According to Fergus Daly, General Manager of HitachiEurope in Ireland, the new ARG IVX+ is energy-efficient,cost-efficient and space-efficient, making it the idealinstallation for modern buildings. It offers excellent flexibilitywith up to 10 connectable indoor units and extended pipingup to 250m.

The new IVX+ unit brings variable refrigerant flow to theinverter split range with fully-independent control. Itfeatures Hitachi’s DC inverter technology to drive thecompressor and fans, resulting in a significant costreduction in annual electricity charges, and a COP of 4.28.

Energy efficiency is also delivered through the newfunctions of “Demand Control” and “Wave Mode”, whichdramatically reduce power consumption.

Available with heating and cooling capacities from22.4kw to 37.5kw, the IVX+ also features new model fin technology to keep noise levels as low as 53bB(A)during usage.

Daly says: “Top-class compact and lightweight designmakes installation of the new IVX+ easier and more flexiblethan ever. Additionally, because the unit uses a horizontaldischarge twin fan set-up, it is extremely efficient on space.The IVX+ is also fully compatible with the Hitachi SystemFree series of indoor units, and with the full range ofHitachi controls”.

Meanwhile, the new S-Series room air conditioningrange has been introduced for applications in both thedomestic and commercial markets. It delivers a COP of6.13 and EER of 6.0, as well as low noise levels of20dB(A). It also has the capacity to destroy airbornebacteria and create a healthier environment.

The sleek, flat-front panel, wall-mounted S-Series unitsincorporate all the features expected from Hitachi, enablingheating and cooling from 2.5kW to 5.0kW. They removeodours as well as destroying 99% of airborne viruses and

bacteria by generating ionised mist from the air in theroom. The RAS SX8 also automatically cleans its micro-mesh stainless filter when the air conditioning operationhas ended.

The “Real Dry” function on the units sets humidity levelswithin the room between 40% and 70% (5% increments),while the function’s “house sitter mode” controls thehumidity in the room with “Real Dry” running automaticallyif levels reach 70%.

The technology is compatible with H-LINK Control/Readyto connect to PCS-6RAD adapter and includes a hard-wired remote controller with built-in 7-day timer.

IntroductionLighting system designersnowadays are presented with thechallenge of providing gooddesigns that efficiently and cost-effectively illuminate morecomplex and challenging spaceswithin buildings. Lighting solutionswere previously calculated andchosen on the basis of providing a blanket lux level in a fully-darkened room and on a flat floor.The lighting designer of today,however, is faced with thechallenge of co-ordinating theartificial lighting system withfactors such as recent legislation,architectural features, the sun and– most importantly – a more awareand less-forgiving end-user.

With many office workersspending a minimum of eighthours under artificial lights, alllighting design should considertheir wellbeing as a priority. It isthe lighting designer’s duty toprovide a comfortably-illuminatedspace that pleases the majority of people within the area. Variousresearch studies have been

published that point to a well-designed lighting system in abuilding positively contributing to the productivity and wellbeing of workers. Some of therecommendations are easily andinexpensively implemented andcould be considered in futuredesigns.

Various studies suggest that thecolour temperature of the lampinstalled can have a bearing onthe productivity of workers. A roomfully illuminated by bright naturaldaylight would be preferable toworkers but this is impossible to implement. The second bestoption is to replicate daylight using artificial lighting. Daylightconsists of all of the visible waveswithin the light spectrum asillustrated in Figure 1.

The human eye perceivesdaylight as having a bluish whitecolour, this short wave light hastwo benefits. The bluish tingedlight is both pleasing to the eyeand also assists in thesuppression of the production of melatonin in the body, a

sleep-causing chemical. Thesuppression of melatonin allows a person to perform moreproductively and remain alert for longer periods.

Fluorescent lamps replicate thebluish tinge of daylight by creatinga gaseous glow within the tubethat illuminates a coating of acombination of differentphosphors. The lamp and coatingsblock individual light wavelengths,yet the blue light passes throughto the external environmentunimpeded. By installing “cool”colour lamps, 5000 Kelvin andabove, that to an extent replicatedaylight, workers should feel agreater feeling of alertness underbrighter lights as opposed to thefeeling perceived under “warm”1500 Kelvin lamps.

Preliminary studies have beenconducted on office workers withlamps that are of a colourtemperature exceeding 17000Kelvin. In these experiments theparticipants reported a heightenedstate of alertness and productivitycompared to the lower colour

temperature experienced under alighting scheme of a lower colourtemperature.

Studies also point to end-usersbeing more comfortable with alighting system when given morecontrol over the light that they aresubjected to. Lighting designs ofthe past were generally controlledfrom one bank of switches thatcontrolled the lighting for the entirefloor. Individuals within an officespace perceive their lightingrequirements in a differentmanner. Allowing each individualworker to choose their own lightingcondition is not feasible in open-plan offices; however, a morefeasible and cost-effectiveapproach would be to follow theBREEAM method for assessingthe environmental performance of a building guidelines.

BREEAM suggests that thelighting control mechanism for anarea should cover no more thanfour work stations; circulationareas and areas penetrated by

daylight should also be controlledindividually. This will allow greaterflexibility and can empower end-users to seek their own preferredlighting levels, thus increasingtheir comfort within their workarea.

A multitude of studies existpromoting various lightingsolutions with a view to increasingthe comfort of the space occupier.The vast majority of these studiesrecommend employing moreadvanced and therefore moreexpensive lighting schemes.Moreover, it must be noted thatthe bulk of these studies arecommissioned by vested interestssuch as lighting manufacturersand, in some instances, therecommendations are in conflictwith the current codes andstandards.

Sun ModellingLighting system designs of thepast would have been one of thelast systems designed for a

building. Nowadays lightingdesigners become involved duringthe building conceptual designphase and have the opportunity to become more involved in thefacade philosophy by providingperformance simulations ofpotential brise soleil and glazingarrangements. Dynamic sun-modelling can pinpoint areas in aroom where daylight penetrationcan be utilised to provide potentialenergy savings by allowing thedesigner to make informeddecisions on which artificial lightsshould be dimmed, and to whatextent.

Dynamic sun-modelling shouldonly be considered for high value,predominantly-glazed buildings asa complete study highlightinginteractions between the artificialand natural light can be time-consuming and costly. Dynamicsun-modelling has been used todate on a number of high-profilebuildings in Ireland and the actualperformance of the final building to

that of the modelled building hasbeen so accurate as to highlightthe usefulness of dynamic sun-modelling programmes inidentifying lighting system energysaving opportunities.

By embracing daylight into aspace, areas of glare are inherent.Surface glare is found for exampleon a desk that is partially exposedto daylight but other parts of thedesk are comparatively darker dueto the lower illumination levelsgiven by the artificial lightingsystem within the room. Surfacesthat are affected by glare can beoptically uncomfortable for thespace occupier but remedies existto counteract this problem.

The use of tinted glazing iscommonly found on buildings tocounteract glare by reducingdaylight penetration. However, thishas a negative impact on the eye’sability to recognise colours. Byincreasing the reflectance ofinternal surfaces surrounding thewindow, the contrast between theoutside and inside surfaces can be reduced, therefore reducingglare.

The trade-off betweenembracing daylight into a spaceand having areas where glare isoptically uncomfortable can be a tricky issue to correct. Facadearchitectural features areconsidered as efficient sunbreakers and there is a tendencyin architectural circles to providesuch features as part of theexternal facade design. In reality, however, only a dynamicmodelling of the sun’s movementscan truly identify if the trade-off

between daylight penetration andglare reduction provided by facadefeatures can be identified.

No single answer is available onhow best to solve glare issues asvariables such as building aspect,location and objects blockingdirect sunlight pose challenges toeach project. As mentionedpreviously, only a complete studyof the individual building willprovide solutions. Let it be notedthat a relatively inexpensiveinternal blind system can providethe space occupier with a fully-functioning, dynamic method ofglare control.

Degradation ofmaterialsWhile the designers of the buildingmay be concerned withengineering matters such asenergy efficiency and architecturalissues, the end-user may alsohave an opinion regarding theentrance of daylight into whateffectively is “their space”. Manymaterials are affected by sunlightdegradation. It is essential that thedesign process takes into accountthe potential damaging affect thatdaylight can have on, for example,furnishings, fabrics, products etc.

Degradation is caused by threefactors:

(1) Spectral composition of the light – counteracted by glazing type/UV absorbing films;

(2) IIluminance – counteracted by removing materials from direct sun;

(3) Period of exposure –sensitive materials should

not be exposed for long periods of time.

Different materials reactdifferently to daylight and it isimportant that the designer takesinto account the conditions thatmaterials in direct sunlight will beunder, and how best to counteractpotential degradation.

Calculating EnergyUsageComplying with the EnergyPerformance of Buildings Directiveis another challenge faced bytoday’s lighting designer. As partof this Directive the energyrequired for servicing a building istotalled and the performance of abuilding is declared in the form ofan energy label similar to theenergy labelling system fordomestic appliances.

With lighting systems in officebuildings using anything frombetween 10% to 30% of the totalbuilding energy consumption, anyadditional capital expenditure onlighting control systems thatreduce energy consumption couldpotentially pay for themselvesmany times over the course of the building life.

IS EN 15193 provides twomethods for the calculation of theenergy required to illuminate abuilding over the course of oneyear. The quick method or thecomprehensive method are useddepending on the complexity ofthe building and the lighting designbut, each method will yielddiffering values based on thefactors taken into account in thecalculation. The result obtained

Future lighting designs should compare favourably with benchmark valuesset down for the lighting energy performance of offices, educational,hospital, hotel, restaurant, sporting, retail and manufacturing buildings asprovided within Annex F of IS EN 15193:2007


from the calculation of the lightingenergy requirement of buildingswill be expressed in indices knownas “Lighting Energy NumericIndicators” or LENI numbers.

The LENI will define the lighting(kWh/m2/yr) energy usage for thewhole building. The lower theLENI number, the more energyefficiently the building isilluminated. The comprehensivemethod will always yield a lowerLENI number as the more detailedcalculation takes into accountmore factors that contribute toreductions in the total lightingenergy consumption.

The quick method allows for theenergy usage to be calculated forthe complete building over theperiod of one year. Tabulatedannual standard values within ISEN 15193 must be used to carryout a calculation based on thequick method. This method requiressignificantly less work than thecomprehensive method but willlead to a higher LENI number.

The comprehensive method is amore detailed version of the quickmethod that calculates the lightingenergy consumption based oneach room within the building, inconjunction with tabulated values

contained within IS EN15193:2007. The comprehensivemethod can be calculated for an annual monthly or time basisbut the extra work involved willlead to a lower LENI number being attributed to the lightingsystem.

Future lighting designs shouldcompare favourably withbenchmark values set down forthe lighting energy performance ofoffices, educational, hospital,hotel, restaurant, sporting, retailand manufacturing buildings asprovided within Annex F of IS EN15193:2007.

Thermal issuesAfter discussing the increasedinteractions between the lightingdesigner and the architectregarding efficient facade design,it is also worth mentioning theadded intrusion on the mechanicalbuilding services engineer’sdesign. By allowing daylight into aspace there can also be potentiallyinherent thermal issues with over-heating of the air mass within thebuilding.

ConclusionThe role of the lighting designer ischanging and various techniques,tools and studies are available tohelp designers make informeddecisions on how best to add tothe satisfaction of clients. With somuch advice and guidanceavailable, the major challengefaced by lighting designers isassessing what information shouldbe utilised in order to improveupon previous lighting systemdesigns. �

Confirming the potential they

demonstrated in the tight finish at

last year’s inaugural event, RACGS

enjoyed a comprehensive win in the

2009 Refrigeration Ryder Cup at the

PGA National. The series now stands

at one apiece and, judging by the

comments over the presentation meal,

the gloves are now off for 2010.

bs news understands that preparations

are already underway across the Irish

Sea with a view to NRG redeeming

themselves next year. “Bring It On”

is the RACGS response!

Arriving at NASA was evenmore fascinating than myexpectations – from the

abundance of NASA police officersfashioning the NASA police uniform, tothe NASA shuttle bus which transportsus around to necessary events.Obviously, organisaton and codes ofconduct are priority here, even downto the timing of the lectures.

Security briefings, cultureorientations and introductionsdominated the first two days. If youhold an American drivers license andare renting a bicycle on campus youcan rack up penalty points veryquickly.

I got to meet Yvonne Cagle, the nextastronaut to travel to space, at the

International Space University openingceremony, where we also received aspecial welcome speech fromGoverner Arnold Schwarzenegger via video link. After the ceremony areception was held in a specially-designed NASA room which includedoriginal shuttles, space suits, a moonrock and much more.

After this relaxed opening day wegot down to serious business. Duringone of our core lectures there was a

live downlink from the InternationalSpace Station during which I, and myfellow-class members, were able toask questions about different aspectsof living in space.

There are approximately 130students from 35 different countries on the programme. Lectures to datehave covered different space topicssuch as law, policy, economics and,most appropriate for me, theelectromagnetic spectrum and thesun. The lectures are presented byexperts from NASA, formerastronauts, and professionals fromother space agencies around theglobe. This is combined with a heavy related schedule, includingworkshops, etc

That said, there was also time out. I celebrated Canada Day on campusby winning the beer ping pong gamewith two of the other Irish students –the Canadians were not too happybeing beaten at their own game! Wethen wrapped up our first week with atrip to the famous Golden Gate Bridgein San Francisco. �

Special Report

DIT Kevin St graduate Paddy Crowley is fast gaining cultstatus among his contemporaries. Last December he wonthe SLL Medal for Excellence at the CIBSE/DIT StudentAwards and, in the spring of this year, got accepted on to theNASA Space Studies Program. This led to a spell studying at the International Space University in NASA in the Summer,from where he sent this initial report to bs news.

The average amount of

water consumed per person, per

day, in the UK is about 150 litres

(in London this rises to 168 litres).

Given the similar lifestyle in Ireland,

the figures are said to be more or less the

same for here. However, these figures are

not a true representation of our water usage

as they represent how much clean drinking

water we use via taps, toilets, bathing and

using the washing machine for example.

Apparently, the shocking truth is we each use

a total of 4645 litres per day – which is the

equivalent of 50 baths of water. Water is embedded

in the products that we drink and consume and it is this

much higher figure that gives us our total water footprint.

We each, on average, use 3400 litres through agricultural crops,

1095 litres through manufactured products and 150 litres in the home.

For instance, it takes 70 litres of water to produce just one apple;

140 litres to produce one cup of coffee; 2700 litres to produce one

cotton shirt; and a staggering 15,500 litres to produce 1kg of beef.

This “embedded” water all contributes to a person’s water

footprint and works on a similar basis to the more widely-known

carbon footprint.

Geordies visit to Arklow Venue Arklow Golf Club

Date: 25 and 26 June 09The Irish BTUs entertained the Geordies (North East BTU)at Arklow Golf Club in the last week of June. In this bi-annualevent – which started in 1990 – there was great craic andrenewal of friendships, which left the town of Arklow very lowon its reserves of Guinness.

The Geordies were led by their Captain, Angus Hynd, wholost out to a home town decision in favour of MichaelMatthews men in a closely-fought duel.

All credit to Brendan Keaveny and Sean Smith fororganising this very successful event.

While extremely enjoyable, the occasion was tinged withsadness as participants remembered Ken Sunderland,principal instigator of the original event, who passed awayearlier this year. However, his spirit lives on in the success ofthis event and the friendship it has fostered between the twosocieties.

back issues Stay CIBSE tuned …While many consultants, just likearchitects, have lost their jobs inrecent months, it is now moreimportant than ever that theystay in the industry loop.Attending CIBSE lectures andavailing of the many networkingand educational supportservices provided is the perfectway to do just that.

Bottom out or rockbottom?The term “bottoming out” is sobandied about as to mean aslight dip or minor hiccup. Itdoes not! Those of you feelinglike things have hit rock bottomare right. It is important not todwell too much on the negative... but let’s be realistic.

Thanks a bunchTerry …You can see from thebemused look on Sean Smith’sface that he’s thinking: “Justwhat the **** do you expect me

to do with this?” asTerry Maher

the BTU Captain’s outing atthe PGA National recently.Terry obviously sees the funnyside too …. just use yourimagination Sean!

Gas safe doesn’t meanplumb safe While the registration of gas installersis undoubtedly a welcome development, it is important to acknowledge that REGIIregistration essentially covers gas works, and does not necessarily denote competencyor qualifications in plumbing.

A case highlighted by CIPHE in the UKrecently clearly illustrated this point. When it was revealed that a householder had been using unhealthy water for two yearsbecause an installer had wronglyconnected mains taps to a stagnant tankof water after fitting a new boiler, the localMP wanted to know if a Gas Safe installerwas involved.

As CIPHE Chief Executive Blane Juddwas quick to point out, Gas Saferegistration in the UK relates to gas, andonly gas. With REGII gas installer registrationcurrently so much to the fore here in Ireland, itis important that the distinction is also madeclear to consumers in this country.

Let’s get O’Leary thinking rail Right throughout the world national Governments are looking to rail tooffset the massive carbon footprint of internal flights. Japan introduced the firsthigh-speed rail system as far back as the Tokyo Olympics in 1964 while France,

Germany, Spain, the US and even China are doing likewise.

Germany has something like 800 miles of high-speed track;France 1250 miles; and Japan 1550 miles. Anyone who hastravelled the Cologne/Frankfurt, Paris/Lyon or Madrid/Barcelonaroutes will testify that it is quicker and far more stress-free thanflying between those cities. It is also significantly more carbonfriendly.

I can’t see ourGovernment rising to the challengeof investing in high-speed rail linksto replace internal flights and longcar journeys but, maybe someoneshould plant the seed in MichaelO’Leary’s brain. In addition to newrevenue sources, he could redeemhis dismal environmental image.
