    Sabien M2G Client Endorsements & Case Studies Sabien M2G Client Endorsements & Case Studies Document Transcript

    • Customer EndorsementsInstitution of Mechanical EngineersWe initially asked Sabien to pilot the M2Gs and demonstrate the savings that would be achieved and,following the success of the trial, the units are now playing an important role in minimising our energyconsumption. We were also very pleased with the support we received from Sabien, which ensured thatthe project ran smoothly,”Brian Robinson, Head of EnergyAEA TechnologyAEA were commissioned to monitor and verify an in-situ pilot of Sabien technology‟s M2G boiler loadoptimiser. The pilot was conducted across 3 sites occupied by BT over a period of 4 months. AEAreviewed the installation of the M2Gs, monitored the pilot process, visited the sites for data collection andcarried out independent analysis of the collated data and verified the savings.Based on the results of the pilot AEA recommended a business case to be made for a large scale order ofM2G as it was clear from the pilot substantial cost and carbon savings could be achieved.AVIVAAVIVA has a well established CSR Policy, and is committed to reducing its impact on the environment. Aspart of this, Norwich Union sets targets each year to reduce its carbon footprint. The reductions achievedby M2G in a wide range of organisations were impressive and we wanted to confirm these ourselves witha pilot scheme managed by Sabien at a number of our sites. Sabien were open and easy to work with,and together with the impressive savings achieved made a strong case to adopt M2G across the NorwichUnion estate” Gregory Luxford, Energy & Utilities ManagerRoyal Bank of Scotland“M2G is a key component in the group‟s energy efficiency strategy and the installation of M2G unitsthroughout our UK fleet of buildings played a major role in helping the bank deliver on its commitment toreducing its energy consumption and harmful carbon emissions. Sabien and M2G delivered”Graham Jennings , Group Energy ManagerCommunities and Local Government“Now that we have validated data following the success of the first three installations we arerecommending the M2G to the various agencies and non-governmental bodies that fall within the remit ofCLG”Carl von Reibnitz, Sustainable Operations ManagerSerco“We were particularly impressed with the results because the pilot took place during the coldest weatherwe‟ve had in 30 years, when dry cycling would have been at a minimum, It„s clear that significantly highersavings will be achieved during more temperate conditions and our ongoing monitoring already supportsthat view. Many people think BEMS can control every aspect of a boiler‟s operation but this is not thecase. The M2G interfaced very smoothly with our BEMS and the two now complement each other tomaximise energy savings”Alan Taylor, Technical Manager, Government Integrated Services www.sabien-tech.co.uk
    • Balfour Beatty"We have formed a strategic partnership with Sabien Technology as part of our ongoing commitment todelivering cost effective carbon saving solutions for our customers. We recognise their product as a wayof driving down carbon emissions from the operation of buildings."Tim Ward, Director Business & IndustryO2“We have been very impressed with the performance of the M2G units. They have lived up to allexpectations and because they are so easy to fit, there was no interruption in service to the two trialbuildings. We are now rolling out M2G to other corporate offices in our portfolio and look forward to seeingsignificantly reduced gas bills.”Paul Eggleton, Energy ManagerUniversity of Derby“Trying to find ways of saving energy and carbon emissions is a large part of my job and for the costinvolved in installing M2G with the resulting short payback, there really was no alternative. We are able tocompare the efficiency savings between those with M2G and those without. This has confirmed that M2Ghas reduced the university‟s carbon emissions”Anne Downes, Energy OfficerJones Lang LaSalle “The energy savings that the M2G can deliver have been fully validated so we now have completeconfidence in recommending it to our customers.”“The BMS at the site in Swindon is very sophisticated and it would have been technically possible to havea special program written to control the dry cycling, but it was more time-effective to use an off-the-shelfproduct, which has potential to integrate fully with existing BMS, particularly when contemplating newprogramming requirements”. “In contrast, the site in Basingstoke, the BMS was simpler and, in fact, evenwith already well-optimised boiler sequencing, achieving even further savings with this system is veryimpressive”.“Sabien responded quickly once we got the go-ahead for the pilot from the client and proved to be veryflexible in accommodating our requirements. We will now be working in partnership with Sabien and ourmaintenance contractor as we look to try and roll-out M2G across other candidate sites.”Mark Bottriell, Jones Lang LaSalle’s Portfolio Energy Manager for Europe, Middle East and AfricaLand Registry“The introduction of this technology has demonstrated our commitment to reduce Carbon emissions. Weare extremely pleased with the results and are looking to introduce the Sabien M2G technology in to asmany of our buildings as possible over the next few years.”Martin Illingworth, National Environment ManagerInternational Students House“We renewed the boiler plant and BMS in 2006 and extended the BMS in 2007 to optimise energyefficiency even further,” explained ISH Chief Operating Officer David Chapman. “I had previously thoughtthat the BMS would also control dry cycling but this was not the case, as the extra savings achieved bythe M2G units have proved.”“The performance of the M2Gs was assessed during the very cold weather at the beginning of 2010, sowe are impressed with the reduced gas consumption under these conditions and can reasonably expectgreater savings in future years. The project was also implemented very efficiently by the Sabien team”.David Chapman, Chief Operating Officer www.sabien-tech.co.uk

    • BT begins rolling out M2GBT one of the world’s leading providers of communications solutions andservices has commenced the rollout of Sabien’s M2G boiler load optimiserfollowing extensive pilots. M2G will be installed, in a rolling program, to allsuitable buildings within BT’s estate of 7,500 buildings.Jeff Nash, Head of Sustainable Estates, BT noted; “BT has a clear focus toreduce its energy consumption and hence its CO2 emissions. It has plansto reduce its emissions by 80% by 2016 in the UK. To help it achieve thistarget it requires innovative solutions from suppliers to help save energyand Sabien delivered on our expectations and will have a continuing roleto play in supporting BT in these plans”Sabien worked closely with Monteray BT’s FM provider during the rollout,providing end to end project management and installation across the UK.How does M2G deliver CO2 savings?The M2G is an intelligent boiler load optimiser which improves theefficiency of each individual boiler regardless of age and size by removing“dry cycling”, an inherent problem found in over 80% of commercialboilers.M2G is retro-fitted to each boiler and monitors the temperature of thewater in the flow and return every 10 seconds, enabling the M2G toanalyse the temperature losses from the boiler. The M2G calculates “M2G’s ability to integrate with existingwhether the temperature loss is caused by a genuine heating demand orfrom standing losses i.e. temperature losses through the boiler casing and Building Management Systems and theflue. When the boiler tries to fire as a consequence of the standing losses vast range of single and multiple boilerthe M2G will prevent the boiler from firing resulting in reduced energy applications regardless of size and ageconsumption. within the BT estate is a significant benefit”M2G’s ability to remove dry cycling within each boiler results in nochanges to the boiler’s designed set points or impacts to ambient room Jeff Nashtemperatures. This approach eradicates previous control methods of using Head of Sustainable Estatesfixed time delays or predictive firing patterns.M2G complements and integrates with existing building controls byidentifying any changes to the boilers set point from building managementsystems or additional controls such as weather compensation.For more information please visitsabien-tech.co.ukor call us0800 082 18 18
    • RAF Odiham reduces energy consumptionby 15% with M2GRAF Odiham has reduced its gas consumption and CO2 emissions by 15% by installingSabien’s patented M2GRoyal Air Force Odiham is based in North Hampshire with a working population of 2,000. Three support helicopter squadrons and oneArmy Air Corp squadron are based there. The installation of M2G was completed on behalf of Scottish and Southern EnergyContracting. Following the installation analysis was completed at the main boiler house which demonstrated gas consumption wasreduced by 15% and payback achieved in just 14 weeks. The payback for the entire site is expected to be 36 weeks, reducing energycosts by over £89k a year.The results were analysed from the onsite AMR consumption data provided by RAF Odiham. The data was degree day corrected tonormalise the impacts of the weather. As the graph below illustrates, gas consumption reduced following the installation of M2Gcompared to previous year despite the weather being considerably colder. Colder weather “The savings delivered were during one of the coldest periods, with boiler dry cycling at a minimum. Yet savings of 15% were still achieved. Lower consumption Quick payback, integration with existing Installation controls and the ease to implement of M2G across an estate have demonstrated M2G as a key technology to reduce energy costs and carbon emissions.” Richard Plester Area Development Manger Scottish & Southern Energy ContractingHow does M2G reduce energy consumption?The M2G is an intelligent boiler load optimisation controller that improves the efficiencyof each individual boiler by removing “dry cycling”, an inherent problem found in over80% of commercial boilers.M2G is retro-fitted to each boiler and monitors the temperature of the water in the flowand return every 10 seconds, enabling the M2G to analyse the temperature losses fromthe boiler. The M2G calculates whether the temperature loss is caused by a genuineheating demand or from standing losses i.e. temperature losses through boiler casingand flue. When the boiler tries to fire as a consequence of the standing losses the M2Gwill prevent the boiler from firing unnecessarily.M2G complements and integrates with existing building controls resulting in substantialreductions of energy consumption with quick payback periods. The combination ofvolatile energy prices and increasing legislation is placing pressure on organisations toimprove their energy efficiency.

One system reduced fuel is energy andconsumption by almost 20% on average without reducing patients’ comfort environmental managerlevels, and had a payback of less than a year, as Robert Spence reports. at Down Lisburn HSS TrustThe Down and Lisburn Health and Social Services Trust is part of theNational Health Service. The trust has a clearly defined energy and Background to the trial The trust decided to evaluate boiler-optimising units as partenvironmental policy with two main objectives. The first is to reduce of its energy policy. Previously, this type of control appeared to beits overheads, wherever possible, so that quality patient care can be fairly basic, but advances, particularly in electronic technology,improved through more effective management of funds. The second suggested that some of these controls had developed considerably,is to reduce harmful CO2 emissions in line with the government’s while others were just starting to enter the market. The trust conductedcommitment to the Kyoto Protocol.
