IntroductionENGINE aimed at helping the engine of the European economy – the 23million small and medium-sized enterprises (SMEs) that provide 75 millionjobs and account for 99% of all European enterprises - become more energyefficient. Smaller businesses seldom have the capacity to systematicallyimplement energy savings.Objectives of the projectImplemented by eight project partners in Austria, Germany, Italy,Sweden and the UK, were to:• Motivate SMEs to implementenergy efficiency measures• Promote innovativeenergy services andfinancing concepts• Train energy auditors and buildup expert pools• Accelerate market introductionof energyservices in SMEs• Communicate energyefficiency to relevant decisionmakers and stakeholders• Disseminate and transfersuccessful conceptsand measuresThe energy checks and surveys carried out as part of the ENGINE projectaddressed SMEs and experts in the metalworking, automotive component,wood, and food processing industries, although all of the energy savingmeasures and lessons learned other than those specifically related to amanufacturing process are applicable to the majority of SMEs.Energy checksThe ENGINE project included 56 energy checks across theregions. The checks comprised the following stages:This publication focuseson the result of the energychecks and addressesenergy efficiency issuesraised by SMEs.For the preparation of thetraining courses a set oftraining materials weredeveloped in all projectlanguages. The coursescovered both energymanagement and energyusing equipment.The training material canbe downloaded from theENGINE• Status quo: Site inspection,data collection, identifyingfocus, interviews• Report preparation:Describing company, analysingdata, comparing energy usewith benchmarks• Evaluation: Calculatingenergy saving potential• Proposal: drafting animplementation plan andsuggesting necessary stepsENGINE offered SMEs an analysis of their status quo by means of energysurveys and checks and worked towards regional capacity building byproviding energy management training.ENGINE has built up a knowledge pool of concepts, instruments andapproaches already available and has launched informational campaigns toincrease awareness on the issue.1

Economic and EnvironmentalBenefits of Energy EfficiencyImproving energyefficiency providesbenefits for boththe organisationinvolved and the widercommunity at local,regional, national, andinternational levels.The main driver for businesses to improve energy efficiency is usually economic:Improved energy efficiency leads to reduced costs, making a business moreefficient and hence more competitive. Reducing energy bills alone is not,however, the only economic reason for improving energy efficiency.The use of more modern process equipment, which tends to be morecontrollable, can also improve product quality and consistency. Morecontrollable building services tend to improve occupant comfort andpotentially productivity at the same time as reducing energy use.SMEs are also being encouraged by their clients, especially larger companies,to improve their environmental performance including energy efficiency, sincelarger organisations are increasingly applying environmental managementsystems such as ISO 14001, which require them to manage not only theirin house production but also their supply chains. An SME with an energymanagement system in place therefore has a competitive advantage over onethat doesn’t, which can be crucial in tendering and subcontracting situations.Achieving the same results while using less energy helps reduce dependenceon imported energy, and helps control the price of energy.Using less energy reduces emissions of a wide range of pollutants, whichhelps improve air quality locally, can reduce phenomena such as acid rain,and mitigates the effects of climate change globally through reducedemissions of Carbon Dioxide and water vapour.2

Practical, Technical, and FinancialSolutions to Common ProblemsThe lack of knowledge of energy efficiency is helped by the availabilityof independent advisers and consultants, and most EU member stateshave government supported programmes designed to provide advice tobusinesses through a variety of media including telephone advice lines, websites, publications, training, and consultancy sessions.Product labelling, especially for domestic scale appliances, can help SMEsidentify efficient equipment. Many pieces of modern equipment are significantlymore efficient than older models due to changes in technology, sometimesspurred by tightening energy efficiency standards: Heating, lighting, and coolingtechnology have all evolved significantly in the last decade.Finance has become increasingly difficult to obtain during the course ofthe project; however there are several sources of low cost funding for theacquisition of energy efficient equipment, such as the Carbon Trust in the UK.Fiscal policies that provide incentives for the acquisition of efficientequipment and taxes on fossil fuels also make energy efficient equipmentand practice more attractive.Public sector leadership, through the specification, procurement, and useof energy efficient equipment not only help to encourage the market andsupply chain for emerging technologies, but can also act as showcases forless familiar technology.The most important steps, however, are some of the simplest: In anycompany, regardless of size, someone should be responsible for energy use,and their work assessment should include assessment of their performancein managing energy. One of the first tasks for whoever is responsible forenergy will almost certainly be to establish a system for measuring energy.Once this is established it is possible to evaluate year on year energy use,assess the economic viability of any potential improvements, and evaluatewhether energy consumption is acceptable. Those responsible for energy useshould be assessed on their management of energy in the same way theywould for other aspects of their jobs.Businesses that have little control or influence over the buildings theyuse have a more limited scope for improvements, although much maybe achieved by establishing dialogue with the landlord. Even if this isnot possible, changes in how equipment is used, and low cost upgrades,especially to control systems and lighting, can still be worthwhile.5

The largest users arethe hardening process, ventilationincluding heating battery,pressurized air and milling machines.The SurveyThrough mapping and calculationsthe energy use was divided in severalcategories as shown in the image.• An investment in modernlighting fittings is also aprofitable measure.• There is a large potentialfor energy saving by heatrecovery from the hardeningprocess as well as thepressurised air system.• By retracting waste heatfrom the hardening process viafiltering to an accumulator tankthis heat can be utilized for hotwater and preheating of theinlet air in the ventilationsystem. Heat recoveryexchangers from the coolingsystem of the two air compressorcan also be connected to theaccumulator tank.• This solution also implies theneed of extra ventilation byopening a large gate whenhardening due to high overloadof heat to the facilities.• Total profitable energysaving measures gives a 25%reduction of the energy use.Chart 1115

Sector Specific Case StudiesBlomdahlsThe BusinessBlomdahls Mekaniska AB is a familyowned company situated in thesouthwest of Sweden. The businessis manufacturing of sheet metalparts for industry and the mainprocesses are cutting, bendingand surface treatment of these.Blomdahls has 28 employees and aturnover of about 2.3 million Euros.Energy PerformanceEnergy consumed is only fromelectricity and about 800MWhper annum.The SurveyAn energy check combined withtraining has been a key part ofthe work for energy efficiency.A big enthusiasm for energysavings has been established.Several actions have beencompleted or are planned for thenear future. Adjusted settingsof ventilation system, improvedlighting, and improvements to thecompressed air system are someof the actions which already savedaround 10% electricity.Key Points• Great enthusiasm is achievedthrough a combination of theenergy check and training.• Savings of around 10% is alreadyachieved almost without anyinvestment costs during the firstfive months of energy work.• Most important for reductionof the total energy use isa change to more energyefficient production equipment,primarily a new oven, for surfacetreatment. The total potentialfor energy savings is roughlyestimated at 30%.16

Sector Specific Case StudiesMaschinen und Formenbau Leinetal (MFL GmbH), GermanyThe BusinessMFL is a well established companyin the outskirts of Hanover whosemain production areas are toolmaking and mould construction.They have 70 employees and in2007 the energy consumption was581MWh in total.Energy PerformanceElectricity is needed for warm waterpreparation and lighting as well asfor the production of compressedair. As for the heating the companyhas a separate oil-fired boiler.Most of the oil-based energyconsumption of about 44% was dueto the heating with the old boilercombined with the inefficient andold circulating pumps. Another11% of the whole electricity usagewas needed for the lighting andnearly 28% was required to producecompressed air.Besides the obvious energywastage at the compressed airproduction another reason gavea strong push towards energyefficiency. A competition washeld by the regional climateprotection agency and others. Totake part it was necessary to havea professional energy conceptdeveloped by a consultant.The SurveyThe energy check covered nearlyevery part of the company but laidemphasis on the following areas:• Heating and hot water system• Lighting• Compressed air• Heat recoveryThe report shows that there weremore potentials then even theauditors had expected and notonly in the energy sector butalso in the water consumption.Although heat recovery is themost important step to reducethe energy consumption, manyother smaller and bigger measurescontribute to help saving costs.After the company had realised thatit is very easy to save energy andmoney the machines and processeswere optimised. For examplethey installed a completely newregulation for the heating system.Now the office and the productionbuilding have got different timecontrolledregulations whichperfectly cover the real needs. Inaddition to the technical measuresthe employees received morecompetences and responsibilities toact autonomously.The energy-concept won a prize of6,000 Euros. And while there was afollow up competition in the regionwhich focuses on implementedmeasures and achieved CO2reductions the companyundertook great efforts to put therecommendations into practice.Such commitments were rewardedwith the first prize and this wasworth 20,000 Euros.Key Points• Compressor heat recovery aswell as waste heat usage of themachines reduced the energyconsumption by around 170MWh.• Another 32MWh were savedby the replacement ofluminescent tubes andoptimisation of the lighting.• The implementation of highefficiency circulating pumpsand a hydraulic adjustmentcontributes to the improvementwith 30MWh.Extract from an interview:“We now know that an importantsuccess criterion for an investmentin energy efficiency is the use ofprofessional energy advisors who worktogether with our management andfind economical and implementablesolutions. Another one is theinvolvement and training of theemployees. Eventually competitionshows us that there is no contradictionin the investment in energy efficiencyand business returns.”17

Sector Specific Case StudiesBartelheimer GmbH, GermanyKey Points• Heat recovery at the endof the powder coatingprocess could save energyof about 137MWh.• Optimisation andregulation of the heatingsystem will cut energycosts by 8,800 Euros.• Another 20MWhcould be saved bythe replacement ofluminescent tubesand optimisation ofthe lightning.The BusinessBartelheimer was founded in 1984and is today well established in themetalworking and metal processingsector and has specialised inpowder coating processes. Thecompany employs 10 people andthe yearly energy usage is about522MWh, emitting 148t CO2. Thetotal annual energy spend is around34,000 Euros.Energy PerformanceElectricity is needed for manyprocesses such as powder coatingand compressed air production.Together with the lighting it coversnearly 20% of the total energyconsumption. Besides the electricitythe powder coating process needsenormous amounts of gas. Intotal 211MWh are used for thatproduction area. That is 40% of thewhole usage and is worth 13,500Euros. And another 159MWh areused for the heating of the officeand production buildings.Nevertheless compared to themetal and coating sector theconsumption structure lies in anormal range.So the main targets the energycheck should have covered were:• Analysis of the energyconsumption and identificationof the main users• Recommendations forimprovements especiallyregarding economical aspectsThe SurveyFollowing the agreement betweenthe company and the auditors thesurvey reveals saving potentials inthis areas:• Heat recovery• Lighting• Heating system• Employee motivation• Compressed airThe survey shows that there ismore potential to discover and tosolve than the company originallyexpected or hoped for. Yet themain barrier to implementing themeasures is cost. Like many othercompanies, they are concernedabout the financial crisis andwon’t invest when the return oninvestment schedules are quiteuncertain. However, low cost andeasy to handle measures wereimplemented immediately, e.g.the leakages in the air pressuresystem have been repaired and thestarting level of the compressor wasreduced to 8 bars.The intention for the future is tohave a closer look at the energyusage and to act step by step. Thereplacement of the old tubes withhigh efficient luminescent tubesor the isolation of the pipe-systemand the restoring of the regulationcould be the next measures.Additionally, the employees shouldbe more involved in the process tosave energy and money.18

Sector Specific Case StudiesU Godsell & Sons Dairy FarmThe BusinessU Godsell and Sons run a 200 headdairy farm near Gloucester. Theannual energy spend is approximately£4,000, emitting 28t CO2.Energy PerformanceThe farm uses mains electricity for hotwater heating, lighting, milking, andrefrigeration. Energy consumptionon the farm is typical for a dairy farm:about a third of the energy is usedheating hot water, a third for coolingmilk, and a third for milking, lighting,and auxiliary equipment. The farmhad already taken steps to considerusing energy cost effectively, andextensive use was made of off peakrate electricity for milk cooling andhot water heating.The SurveyThe survey provided an assessmentof the energy situation coveringtwo main themes. The first coverstechnical opportunities for reducingenergy consumption/cost assessingthe following areas:• Heating and hot water• Milking equipment• Lighting• Milk cooling equipment• Renewable energy opportunitiesThe second looks at management ofenergy use (monitoring consumption,and understanding how staff useenergy). Energy use at the farm wasfound to be well managed. Unusuallyfor a small business, the principalrecommendations were only fortechnical improvements related toequipment, rather than user practice.These were:• Increasing capacity of the springwater milk chiller• Installing a variable speed drive(VSD) on milking equipment• Installing heat recoveryequipment on milk chillers.Key Points• Improving cooler will reduceannual electricity demand formilk cooling by £300.• Variable speed milking pumpswill cut annual milking pumpenergy use by £250.• Compressor heat recovery willcut annual hot water heatingcosts by £100.The installation of a variable speeddrive has already cut electricityconsumption by 20% and will payfor itself in less than 5 years. Theimprovements to the chiller, costingaround £1,000 will lead to annualsavings of approximately £300. Heatrecovery equipment to preheat hotwater using waste heat form themilk chillers costs approximately£1,000 and provides annual savingsof £100. The savings may appearmodest as they are based on 2007electricity prices. It is expected thatactual savings in the medium term,and returns on investment, will bebetter than those quoted.19

Sector Specific Case StudiesGloucestershire Engineering FirmKey Points• Improving lightingefficiency to save 15%of total electricityconsumption (72MWh)per annum.• Heat recovery from thecompressor to reduceheating demand by8MWh per annum.The BusinessSevern Wye Energy Agencyconducted an energy check ofa Gloucestershire engineeringcompany from April to August2009. The Engineering Companyis a well established manufacturerof roller and ball bearings, basedin the South Midlands area of theUK. The premises houses offices,production, and storage areas formaterials and finished products.Energy PerformanceThe business has annual energyconsumption of approximately340MWh of gas and 490MWh ofelectricity. Electricity consumptionaccounts for over 80% of theenergy bill in a typical year. Themajority of energy used at thebusiness is for lighting, production(metalworking), and heating. Staffat the business were aware of thesignificance of energy consumption,and were keen to find practicalways to reduce energy consumptionwithout affecting the core business.The SurveyIt was clear that although theproduction processes weresignificant users of energy, it wouldbe difficult to reduce productionenergy use since most was frompackaged machines such as CNCequipment. The compressed airsystem was checked thoroughly, asleaks are costly and can be repairedcheaply and easily. No leaks werefound, indicating that the systemwas well maintained.The largest potential for energysaving was found in the workshoplighting, since most of theworkshop were lit by fluorescenttubes operated by electromagneticcontrol gear. Assessment showedthat replacing the existing lightingwith modern metal halide lighting(such as that already fitted onone area) or modern fluorescenttubes with high frequencyelectronic control gear wouldreduce electricity demand byapproximately 72MWh per annum –approximately 15% of the electricityconsumption. Changing the lightingwould also reduce maintenancerequirements.The other significant savingidentified was to duct warm airfrom the compressor house into themain building during the winter toreduce heating demand by 8MWhper annum. Smaller measuresidentified included improvinginsulation levels in the officeaccommodation and installing moreefficient gas heaters and boilers.20

Energy ManagementSystems and ServicesThe ENGINE project was not about reinventing the wheel or encouragingSMEs to experiment with untested technology, but about enabling smallercompanies to take advantage of the technologies and management toolsalready used by more energy intensive industry.The ENGINE programme has clearly demonstrated that it is possible forsmaller companies to reduce their energy consumption through theimplementation of an appropriate energy management system. The mainbarriers to doing so are the lack of resources (mainly time and money) andthe large numbers of companies who rent premises on short term leases.The market for energy efficient equipment is constantly evolving, drivenby market demand and regulation of energy efficiency, although it tendsto be larger companies that have the resources to prioritise and evaluatequality, reliability, and energy efficiency when acquiring new equipment,whereas smaller companies frequently acquire equipment based on costand ease of availability.The demand for energy management in small businesses is increasing,driven both by the general trend of ever rising fuel prices, and that of largercompanies demanding better environmental standards from their suppliers.During the course of the ENGINE programme, the international economicsituation has changed considerably, with global supply of credit and demandfor products, services, and energy falling, reversing at least temporarily thetrend of ever increasing fuel prices, and leading to a situation where manybusinesses are unable to invest in non essential investment. Even underthese conditions there is still potential for most businesses to save energythrough better use of existing equipment or through low cost investments,for example in better control equipment. Although the ENGINE programmelooked at specific industry sectors, the examples are applicable to most SMEs.There is market potential for almost all SMEs to cost effectively reduce theirenergy consumption. The availability of ever more efficient technologyand impartial business advice services will aid the adoption of technicalsolutions. The move toward automated metering among ever smaller energyconsumers will make the collection of energy data simpler and cheaper, andthis will make the implementation of a more formal monitoring and targetingor energy management system.21
