MANAGING EDITOR Mark Thrower

Turn on any news bulletin in the last few weeks and you can guarantee a mention of the size of the new prime minister’s in tray. Well, Liz Truss’ desk will have to be reinforced to cope with the weight of the tasks piling up for her. Energy will be at the top of the pile because the word ‘energy’ is now all too frequently accompanied by the word ‘crisis.’ A lackadaisical approach to long-term planning of the energy market has partly got us into the mess we find ourselves. Priority has to be finding a short-term sticking plaster to get us through the coming winter. Consumers’ bills – both domestic and business - will have to be subsidised. That’s what it amounts to. But we need a long-term plan to end our obsession with oil. Truss can look to what is happening in Europe where plans, both short and long term, have already been put in place (see page 10). In Spain, the government has ordered businesses to limit air conditioning to 27⁰C in summer, and heating to 19⁰C in winter. Both shops and public buildings are to ensure doors are not left open when heating or A/C systems are operating, and must go dark at night. But most of all Germany is setting about reducing the most wasteful gas usage, still to be found in its older buildings. The present federal government is setting aside the colossal sum of €56.3bn entirely devoted to the energy renovation of buildings between 2023 and 2026, concentrating upon the 40 per cent of homes heated by gas. That is the equivalent of spending £14.5bn every single year upon retrofitting energy efficiency. Elsewhere it is reckoned that support packages for households are set to be around €49.5bn in Italy, €44.7bn in France. The sticking plaster of the next few months must be accompanied by a long-term plan for the UK to use less energy and reverse the blatant ignoring of energy efficiency. Just 126,131 homes received help with work such as loft and cavity wall insulation through the Energy Company Obligation scheme in the first six months of 2022. This is a 51 per cent fall on the 261,315 installations carried out in the same period last year. This appalling decline must be reversed.Thisis a crisis that needs a short-term fix but long-term plans to ensure that it can never happen again. I hope that message is in the Truss in tray.

Editor’s Opinion

If households and industries use more energy to cope with the ongoing and expected changes in climate conditions, the mitigation challenge will look inherently different depending upon its overall success. Importantly, “the more ambitious the target to cut greenhouse gases, the less achieving this will increase fuel consumption.”Inascenario where the ambition of mitigation policy is lackadaisical, climate adaptation will contribute to further exacerbating the risk of lock-in into polluting fossil-fuelbased generation in the next few decades. The potential additional final energy demand identified - and the resulting energy costs- could be cut by 50 per cent when aiming at limiting increases of 2.5 °C targets. That extra demand could diminish by up to 75 per cent if the target of well below 2 °C, set in the 2015 Paris Agreement, is achieved.

NEWS UPDATE EIBI | SEPTEMBER 202206

Even in meeting the Paris Agreement target, an additional 10 exajoules(EJ) of energy demand would be required annually by 2050. That would add 6 per cent to current worldwide consumption. If power is not fully decarbonised, by 2050, adaptation could need “an average annual addition of new fossil-fuel capacity of about 55GW, which corresponds to around 1 per cent of the currently installed global annual new investment decisions for gasfired generation.” The conclusion is stark: “As a consequence, energy system costs and carbon prices will increase because of adaptation.”

Adapting to climate change will increase energy consumption of mechanism to protect these customers is years away from delivery.However, Heat Trust says in the meantime government should move on emergency financial support and invest to increase efficiency on district heating systems.Thisoffers a way to reduce costs passed onto customers both now and in the future, says Heat Trust. It argues that the planned government scheme to fund efficiency improvements to heat networks must be accelerated and scaled-up. Many heat networks have high heat losses, which means customers are paying for heat they don’t even use. Some heat network customers are already seeing bills as high as 50p/kWh – or around £5,000 per year for the average household. It is predicted that could rise as high as 70p/kWh, or £7,000 a year, for the average household – with winter heating and hot water bills of almost £1,000 a month for some.

Energy consumption fuelling efforts to adapt to climate change will “increase considerably over time and with warming,” a new study warns. The researchers, drawn from the economics department of the University of Venice, have sought for the first time to “quantify the impacts of adaptation actions entailing direct changes in final energy use on energy investments and costs, greenhouse gas emissions and air pollution.” Published in the latest issue of Nature Communications, the researchers warn that, in the short-to-medium term, much of the additional power generation capacity for these energy needs will be fossil fuel based. Accounting for this “adaptation-energy feedback” in mitigation pathways “requires a higher global carbon price, between 5 per cent and 30 per cent higher,” the study concludes.

Households using district heating could be facing bills as high as £1,000 per month for heating and hot water this winter, prompting a call for government to step up its pace in making energy efficiency

The lights will stay on this winter, insists DEFRA Scares about energy-rationing controlled blackouts this winter are unnecessary, and “not something we expect to happen,” insists a spokesperson for the Department for Environment, Food and Rural Affairs (DEFRA), the DEFRA spokesperson said, adding that “businesses and industry can be confident they will get the electricity and gas they need.” Equally concerning for industry are skyrocketing energy prices, with no price cap limiting the maximum energy costs businesses can be charged in Britain in a given month, as there is for households. “This is putting food and drink manufacturers “under extreme pressure,” said Karen Betts, chief executive of the Food and DrinkEightFederation.percentof manufacturers say “the rise in energy costs is now so severe they are ‘business threatening,’” said a spokesperson for manufacturing lobby group MakeUK, citing recent polling. “We are now at a tipping point when it comes to price increases,” they warned. In 2022 alone, the UK’s automotive sector expects an additional £90m in energy costs, according to Mike Hawes, chief executive of the SMMT, the industry’s main lobby group in Metalforming, representing 200 firms and 40,000 jobs. His members are being asked to renew energy contracts, based on a four-to-sixtime price hike this winter as Russia’s invasion of Ukraine strangles gas supplies, sending prices spiralling out of control. “That is simply not commercially viable,” he said. Many company bosses “feel they have no choice” and will take their chances on the ‘day ahead’ energy market, Morley explained, “hoping that the situation with Russia/Ukraine improves, we have a mild winter, and domestic users cut back on their usage.” Locking into a contract now “will mean business failure.” Earlier this month, former British Business Secretary Kwasi Kwarteng announced plans to exempt “energyintensive industries” — including steel, paper, glass, ceramics and cement — from green-energy levies to help them with their costs. Yet this is a minor relief compared with the scale of gas price increases, but even so “seems to help the big boys and neglect SMEs that account for tens of thousands more jobs,” Morley said. “I’m afraid the government can’t even sort out the short-term issue, let alone the longer term.” Britain. “That’s a real challenge for the industry because, obviously, you’re trying to compete with other locations, specifically in Europe,” Hawes said, pointing out that UK energy prices are more than 50 per cent higher than the EU average.

The IEEFA analysis has concluded that, even were Enchant Energy to manage to capture 90 per cent of the CO₂ produced at San Juan, the combined CO₂-equivalent (CO2e) capture rate for both the mine and the plant would be far lower, at around only 68 per cent. In that scenario, the project would continue to emit almost 3m tonnes of CO₂ annually. For scenarios in which Enchant only captured 75 per cent or 65 per cent of the CO₂, the effective capture rates would fall to just 57 per cent and 49 per cent, respectively.“TheEnchant project provides a good opportunity to review the effectiveness of carbon capture, due to the breadth of publicly available data on the production and emissions at both the plant and the mine,” said David Schlissel, IEEFA director of resource planning analysis and co-author of the report. “The findings in this study can reasonably be applied to other carbon capture projects including those from other coal plants, from gas-fired plants and from proposed blue hydrogen projects.”

The efficacy of industrial carbon capture is being grossly overstated, according to new research from US think tank the Institute for Energy Economics and Financial Analysis (IEEFA).

HyDeploy will continue to test the safe use of blended hydrogen for domestic and commercial use. In The first phase of HyDeploy saw 100 homes and around 30 commercial buildings on a closed network at Keele University successfully use the hydrogen blend for a period of 18 months which ended in the spring 2021. Dr Angela Needle, director of strategy at Cadent, said: “By blending hydrogen into the gas network, the people in Winlaton could start using a greener gas without having to make any changes to their home or the way they use their heating and cooking. Forming part of the evidence we are putting to Government to enable their 2023 policy decision on blending hydrogen into the gas networks as a means to support decarbonisation targets”.

Efficacy of carbon capture ‘is being grossly overstated’

A project operated by Northern Gas Networks in Winlaton, Gateshead, has proved that blending 20 per cent hydrogen into the gas grid is a safe and effective way to lower the emissions from heating homes and public buildings.

addition, there are ongoing projects testing the use of hydrogen for heat, including the Hydrogen Homes at Low Thornley near Gateshead, where 100 per cent hydrogen can be seen in use in a show home boiler, cooker, hob, fire and even a barbecue.

Farmers cut back on carbon reductions as costs rise with stronger environmental credentials (49 per cent), improving the energy efficiency of their premises (54 per cent) or increasing renewable energy usage (57 per cent).

Earlier this year Ofgem shortlisted two UK locations for a Hydrogen Village demonstration, which will see natural gas swapped to hydrogen in around 2,000 properties.

The shortlisted locations are an area of Redcar in the North East and Whitby, Ellesmere Port in the North West.

NEWS UPDATE EIBI | SEPTEMBER 202208

Analysing the life cycle emissions of Enchant Energy’s proposed retrofit of the San Juan Generating Station in New Mexico, the study concludes that the overall carbon capture rate from both the power plant and the mine that provides its coal would be, at most, 72 per cent. This, according to IEEFA, flies in the face of industry-wide promises of a 95 per cent capture rate. Prior CCS studies have never been in a position to look at the full life cycle of emissions of carbon capture and storage projects. A gas-fired generator, for example, could have a theoretical 90 per cent capture rate over the long term. But would still produce significant methane leaks during production of the natural gas used at the site and during its transportation to the generator –as well as from the CO₂ pipelines and underground storage facility.

The online vote will be the sole factor in determining who will be shortlisted to win the award in each category, with the ultimate winner to be announced at the inaugural prizegiving event. All those shortlisted for an award will be invited to attend the Energy Saving Awards at The Tower Hotel, London. The event will take place at lunchtime, 1st December 2022. Already, leading industry names such as Navien are leading the list of sponsors. Category sponsorships are still available.

In response, the Energy and Utilities Alliance (EUA), which represents the interests of gas suppliers and manufacturers, has stated the subsidy would be more effective if targeted towards energy efficiency measures in the home, reducing bills for Brits reportedly already in debt on average of £206 to profiting energy companies.

The total scheme, over three years, amounts to £450m subsidising 90,000 heat pumps. That same amount means nearly 1m homes could get free insulation, cutting bills by nearly £220m a year. Surely that’s the greater prize in these difficult times?”

Speculation that the energy price cap will soar to £4,200 in January has prompted the Energy and Utilities Alliance (EUA) to question whether subsidising heat pump installations is the best use of taxpayer’s cash.

Germany’s Climate and Transformation Fund aims to reduce the 30 per cent of the country’s total energy consumption used to generate space and water heating, with an emphasis on improving buildings in the bottom 25 per cent of energy performance. This also represents a dramatic shift in government priorities from supporting the construction of new homes to renovating more existing ones, with one government official saying: “One euro spent on renovation is ten times more efficient than if it was spent on a new home.” Other European countries are expected to announce similar plans with the EU intensifying the focus on retrofit in its planned revisions to the Energy Performance of Buildings Directive. “This looks like a comprehensive plan for retrofitting buildings with both net zero and reduced energy costs for consumers in mind,” said BESA’s head of technical Graeme Fox. “We have long been calling for something similar in the UK and I would urge our officials to look at this closely. Germany is grappling with the impact the Russian invasion of Ukraine has had on its gas supplies and has pledged to invest €35.5bn in its renewable levy to lower electricity prices, with another €20bn going towards decarbonising industry and developing the hydrogen industry. German consumers no longer pay the renewables levy that helps to finance the expansion of wind and solar power. Instead, the government has stepped in as part of efforts to cut electricity bills, but without reducing its investment in renewable infrastructure.

Britain’s ‘hands-off’ approach to cutting energy use is in stark contrast to the high-spending governments of other major European economies T he International Monetary Fund has a new pin-up country on energy policy. Very loudly it is warning European Governments against intervening in the region’s worsening energy crisis by just offering broadbased financial support. Saying instead that consumers should be bearing the brunt of higher prices, in order to encourage energy saving and the wider shift to green power. That is very much not the way the 27 member governments of the European Union have been approaching the unprecedented escalation of fuel prices. But at the time of going to press, that hands off approach seemed to be very much how the UK’s new Prime Minister is inclining. Preferring some limited

Elsewhere it is reckoned that support packages for households are set to be around €49.5bn in Italy, €44.7bn in France, even €27.3bn in Spain.Above all, it is Germany that is trying to avoid concentrating upon providing too many subsidies to fuel bills, other than for key industries. It is determined to try to address the real long-term problem, with elderly buildings simply requiring too much fuel to operate efficiently. As one prominent commentator put it, “there is little point in trying to fill the bath with hot water, if you fail to put the bath plug in properly.” A sentiment echoed all too often in the UK. But as yet, seldom acted upon. ■

Like Spain, where the government has ordered businesses to limit air conditioning to 27C in summer, and heating to 19C in winter. Both shops and public buildings are to ensure doors are not left open when heating or A/C systems are operating, and must go dark at night. Electricity savings are deemed just as important, because 31 per cent of Spain’s power has been gas-generated. Within one week, energy use fell by 6 per cent, according to energy minister Teresa Ribera, who states that households are following these well-publicised examples.Indeed,throughout Europe it seems that governments are quite deliberately opting to promote energysaving measures that catch the eye of voters, either as employees or as customers, to increase awareness of the potential for, as it were, turning home thermostats down. Similar requirements on maximum and minimum temperatures are being required both in Italy and in France, where an “energy sobriety” plan is being issued this month, intended to slash French energy consumption by 10 percent compared to 2019 by 2024.Energy Transition Minister Agnès Pannier-Runacher intends to ban illuminated advertising in all cities during the night. Italy, where 70 per cent of homes are heated by gas, Is marketing heavily its arrangements to refund 110 per cent of the costs of installing certain agreed energysaving measures, a scheme that is also helping to eliminate cash-in-hand broad based financial support to voters, rather than anything more targeted or sophisticated to encourage longer-term energy saving.

THE WARREN REPORT 10

Germany is trying to avoid providing too many subsidies to fuel bills also due to the departure of Russia’s Gazprom from practically all the European trading market, exacerbated by outrage at that country’s invasion of neighbouring Ukraine. This summer it was agreed by the 27 EU governments that, between August 2022 and March 2023, collectively the EU would reduce natural gas consumption overall by 30bn/m. This equates to a drop of around 15 per cent. Such a collective decision is surely the first time that EU members have ever agreed to undertake such a major collective short-term energy policy objective which has such an overt impact upon its citizens.

Continent-wide drive Elsewhere in Europe, there is a continent-wide drive to create innovative policies designed to reduce the overall demand for fuel. These initiatives have been stimulated by the tenfold increase in the wholesale trading price of natural gas, prompted in part by extra demand following the bounce-back from COVID 19. But

black-market transactions. Like Latvia and Bulgaria, the Czech Republic has been almost entirely dependent upon Russian gas. Average gas consumption per Czech resident is also 20 percent higher than the EU average, meaning demand reductions could have a significant impact. There has long been pressure upon former-Comecon countries to use structural and other funds provided overtly for “levelling up” purposes from the European Commission, to improve the building stock. The Prague Government is planning a windfall tax upon energy purveyors, to ensure that no household this winter will pay more than 30 per cent of disposable income on housing and fuel.But it is Germany that has been the most dependent country upon natural gas from Russia. Now it has been purposefully building LNG bases and restocking its gas storage facilitieswhich unlike in Britain have not been closedBritaindown:willlong rue the approval given by the then-Chief Secretary of the Treasury, Liz Truss, in 2017, to closing Centrica’s Rough storage facility.

An innovative motor starter could help extend the lifetime and reliability of high torque single phase heat pump compressor motors, says Will Darby avoid excessive wear and tear on the orbiting scroll. In addition, the HDMS’s algorithm will enable the motor to be started with less than 1.5 times the compressor’s rated current.

A major benefit of having 6m heat pumps running off electricity, rather than relying on gas boilers, is that they will help lower the carbon emissions from heating the UK’s buildings. Heat pumps will also help to wean the UK off gas, reducing its reliance on imported fossil fuels from places like Russia, which will also be beneficial for energy security.

Faulty starting capacitor

A major advantage of the HDMS, when compared to direct online (DOL) starters, is that the soft-starter can reduce start-up current by up to 75 per cent, which can also help improve reliability by reducing alarms in applications with a weak power supply.

To help improve heat pump reliability, Carlo Gavazzi has developed a unique soft starter for CSCR motors that eliminates the need for the starting capacitor. Its patented High Dynamic Motor Starter (HDMS) features an innovative algorithm that ensures sufficient torque is generated to start a CSCR single phase motor. By eliminating the start capacitor, Carlo Gavazzi expect the HDMS to help manufacturers extend the lifetime and reliability of equipment reliant on a single phase CSCR motors.

And, in some instances, a lower startup current might even help reduce utility tariff costs.

The HDMS features Carlo Gavazzi’s third generation self-learning algorithms, which means the unit is able to continually improve motor starts without the need for user input. The unit is shipped with default current limit settings, equivalent to 1.5 to 1.8 times the rated HDMS current. For every motor start, the HDMS takes a number of measurements so that over time it will adjust the internal parameters to reduce the starting current during the subsequent motor start. And because the self-learning routine is active at every start the unit will ensure an optimal start even when load conditions change and when the motor ages. Machine downtime is further reduced through the use of conformal coatings - a thin polymeric filmapplied to the printed circuit board (PCB). This helps protect the PCB’s components from the environment andIncorrosion.use,theHDMS’s Modbus RTU interface offers the option for remote monitoring and quicker fault-finding via the history record, while also allowing connection to a PC for real time monitoring of energy and operating variables. Furthermore, the unit’s NFC feature enables stored data to be downloaded to any Android smartphone and tablet to allow data to be downloaded and shared.

● after this, the motor will work more efficiently with a run capacitor. The run capacitor will bring the motor’s start winding back in phase with its run winding to provide the running torque once the motor is up and running. Run capacitors are designed for continuous duty while the motor is powered.

A common cause of problems in motors is a faulty starting capacitor Capacitor start/capacitor run (CSCR) motors are commonly used to create the high starting torque required to power the scroll compressors commonly used in heat pumps refrigeration circuits. Traditionally, CSCR motors have incorporated two capacitors: ● the start capacitor is used to increase the phase angle between the start and run windings of the motor. This helps create greater torque at start up and enables the motor to be cycled on and off rapidly. The start capacitor stays in the circuit long enough to rapidly bring the motor up to a predetermined speed, which is usually about 75 per cent of the full speed, and is then taken out of the circuit; and Managing director of Carlo Gavazzi Will Darby www.carlogavazzi.co.uk

Let’s talk about torque

The majority of these 6m heat pumps are likely to be installed in new-build properties and will be connected to a single-phase electrical supply. Come 2035 that will be a lot of single-phase heat pumps with a lot of compressors stopping and starting.

To measure electricity consumed by the unit some heat pumps have built-in meters and monitoring devices, known as on-board meters.

Another metering option is to use a stand-alone electricity meter to measure the electricity consumption of the heat pump. For single phase new heat pump metering applications, Carlo Gavazzi’s EM100 series of energy meters offer a cost effective, compact and MID compliant solution for on-board and standalone applications. ■ T he UK government has ambitions for 600,000 heat pumps a year to be installed by 2028. That could see as many as 6m heat pumps installed by 2035, according to the government’s “back of the envelope calculation.”

The HDMS has a maximum rampup time of one second, making it particularly suitable for starting scroll compressor motors which, generally, must start within 800 milliseconds to

One of the most common causes of malfunction in this type of motor is a faulty starting capacitor. If the startcapacitor deteriorates the amount of electrical charge stored can change, which can lead to problems with starting torque that could prevent the motor from starting, tripping the motor’s overloads. Similarly, if the start capacitor short-circuits this could result in motor winding burn out.

Installing a more efficient, wellcontrolled heating system, for example, will meet two common business objectives, driving down building energy consumption and reducing its carbon footprint. And now, with the ready availability of tailormade, prefabricated solutions, much of the hassle associated with installation can be Whetheravoided.installing a complete packaged plant room, an energy centre or a pre-assembled replacement boiler rig module, carrying out most of the manufacturing off site in a qualitycontrolled factory environment brings numerousCrucially,benefits.thanksto the use of specialist machinery, improved control procedures and end-of-line testing, the highest build quality can be achieved. At the same time, this technique has the potential to reduce waste, leading to a lower environmental impact.

A bespoke rig boiler system can save a significant amount of installation time system connections on the rig can be designed to match the existing system pipework in the plant room. So, unlike site-assembled, flat-pack cascade packages, bespoke rig solutions can require zero onsite fabrication. Complete packaged plant rooms can similarly be purpose-designed in sections or as a single lift, depending on the site requirements, to enable straightforward transportation, accurate positioning and easier installation.Importantly, using a packaged solution means that there is one point of contact for the whole system. The one-stop-shop system integrates the heat source – which might be any combination of boilers, combined heat and power, air source heat pumps and gas-fired water heaters – with pumps, controls and accessories such as a dosing pot and pressurisation unit. Consequently, using a complete packaged solution reduces the potential for delay, helping to keep the project on schedule and avoiding any last-minute hitches due to product availability. This is particularly beneficial on projects where installation must be completed within a fixed timeframe, for example on school projects.

A bespoke rig system has been installed by social housing provider Wakefield and District Housing (WDH) to replace the ageing boilers serving the district heating system at their Smirthwaite Estate in Yorkshire.

The skids connect onto two prefabricated frames accommodating the pumps and high-level pipework. These fit against the walls, leaving sufficient space for the CHP and the two buffer vessels situated at the opposite end of the plant room. Ultimately, the goal with offsite fabricated solutions is to encourage early collaboration on the system design to achieve a solution that meets all project requirements. And by engaging with designers, clients, contractors and offsite manufacturers like ourselves from the outset, energy managers can ensure that long-term efficiencies are addressed in the design to help manage the rising business energy costs. ■

The requirement was to improve the efficiency of the heating system with minimal downtime and disruption to residents. As renewable technologies were not a feasible option on this project, Rob Wilson, consultant at Building Services Solutions, specified installing eight high-efficiency Remeha Gas 220 Ace boilers in a back-to-back arrangement using a Remeha offsite fabricated cascade system with a Plate Heat Exchanger (PHE).

Unique requirements A key advantage of prefabrication is the bespoke element. This is what makes it possible to address and resolve the unique requirements of each project and achieve the best possible outcome. Take space, which is a frequent project challenge. Prefabrication enables the best use to be made of the available spaces, whether in a small or hard-to-access basement plant room or a full roof-top packaged plant room.

With the joint challenges of rising energy prices and increased blackouts Matt Watson discusses how hired Energy as a Service (HEaaS) models can help operators navigate this troubling period.

With these factors in mind, it is clear that operators cannot continue to place the security of their business in the hands of their grid connection, with both rising energy prices and power cuts of growing concern. It may be time for operators to look towards generating their own energy on site in order to decrease reliance on traditional energy sources. Within BTEG, 48 per cent of respondents said that they have considered generating their own energy. Revisiting this in The Power Struggle – Manufacturing, this figure has grown to 60 per cent, indicating that energy crisis has indeed led some businesses to revaluate their approach to energy procurement.

251 manufacturers across the UK, from junior manager up to C-suite executive, as part of its latest report, The Power Struggle – Manufacturing.

However, investing in the technology required in order to begin generating energy on site can be expensive, with capex restrictions identified as a key barrier to entry in BTEG. However, with concern about the impact on production processes now a leading issue, 58 per cent now hire equipment in order to bypass budget restrictions.

The Government has since issued a relief package to help alleviate pressure upon the sector. However, it is important to recognise that the energy crisis is a symptom of larger long-term challenges surrounding the security and sustainability of energy procurement, as outlined in Aggreko’s 2019 report Bridging the Energy Gap (BTEG).Forinstance, in 2021 the Energy Intensive Users Group (EIUG) warned that the spiralling cost of energy could lead to halts in production, with this prediction manifesting in 2022.

Generate energy on site Hire can often take the form of an Energy as a Service (EaaS) contract, wherein businesses generate their own energy on site through decentralised energy solutions. This allows operators to decrease dependency on the grid without having to sacrifice capex for the outright purchase of equipment. Traditional EaaS contracts come in the form of long-term fixed energy pricing. With such volatile energy prices, it is easy to see how this can turn into more of a potential danger than a solution, especially given that some providers reserve the right to issue high demand penalties to their customers if their demand changes. Here, the solution may lie in a slight adaption of this model, in the form of Hired Energy as a Service (HEaaS). This approach offers the same benefits without locking users into strict fixed term energy pricing.

The findings appear to chime with the concerns outlined above, with 66 per cent of those surveyed stating that rising energy bills had significantly impacted their profit margin in the past two years. Moreover, 65 per cent also claimed to have experienced a power cut in the last 18 months, leading to production delays and temporary shutdowns.

Instead, HEaaS contracts guarantee flexibility, with operators able to scale their output up or down as desired to help work around demand.

It is apparent that the current energy crisis is posing a risk to industry in the UK. Compared to other parts of the continent, the nation’s dependency on gas power has left it exposed to fluctuating energy prices and increasingly frequent blackouts. With competition from overseas growing stronger by the year, this has threatened the position of the UK within the global market. The widespread effects of the energy crisis have left virtually no sectors unaffected, with manufacturing no exception despite an annual output of £183bn. However, with the sphere currently supporting over 2.5m jobs and 64 per cent of all domestic business research and development, it is critical that this challenge is overcome in the interest of the national economy. In an effort to evaluate the extent of this challenge, Aggreko surveyed

A short-term aid As businesses continue to wrestle with the energy crisis, it is important to recognise that the challenges brought about by this period are by no means new, and will likely reoccur in future. Government support remains only a short-term aid – therefore, it is critical that manufacturers re-evaluate their approach to power procurement in order to provide greater security for their production line going forwards. By adopting more flexible energy models such as HEaaS, operators can secure their supply in the face of fluctuating energy prices and an unstable grid, without the need for upfront investment or being locked into strict fixed term agreements. In such a tumultuous period, the number one consideration should be partnering with a supplier than can be as flexible to the demands of the market as the business themselves, in order to successfully navigate the energy crisis. ■

With rising energy prices, investing in energy efficiency can provide real savings, ensure superior process performance, and real financial outcomes, says Dave Palmer allows maintenance when it is needed and not just because the schedule says it’s time. With budgets under pressure, predictive maintenance is a good means of controlling costs and reducing the likelihood of a temperature control system failure that could shut down your operations.

Tips to reduce heating costs across industry

Live condition updates Alongside a preventive and predictive maintenance approach, there are technologies and services available that allow 24/7 access to live condition updates and the history of your assets, enabling you not only to oversee performance and energy consumption, but also remotely change set-points for better uptime, productivity, and efficiency. With these capabilities, you can combine data analytics, connectivity and expert support to maximise productivity and energy efficiency of the heating and cooling systems. Remote monitoring services enable remote technical performance and energy monitoring as well as thorough fault diagnosis, reducing unnecessary site visits and optimising maintenance operations. We calculate that customers can reduce maintenance visits at their site by 50 per cent, resolve even 75 per cent of the issues on a first visit and reduce up to 55 per cent of operational expenses related with the temperature control equipment.Byputting data to work, and pairing it with technical expertise, you can not only have full visibility of the units and expert support to optimise and maximise the equipment’s productivity, but also leverage this intelligence to better plan investments and resources to improve your business’ profitability and growth.

Over the last few years, innovations in process cooling and heating systems have led to innovative designs that can offer significant benefits compared to systems that they are designed to replace. With a new generation of low global warming potential HFO refrigerants, you can achieve temperatures of even 120°C with water-sourced heat pump systems.Innovation and new technologies usually bring increased efficiencies and other benefits.

The traditional approach to maintenance relies on a calendar or hour meter to determine when equipment is serviced. But technology gives us actionable information that in the industry does though is look at cooling and heating at once. There are new opportunities ahead if we start looking at heating from the cooling perspective and the opposite. While pure heating heat pump solutions require external (sustainable) heat sources such as air or (ground) water, combined heating and cooling applications provide unique opportunity to reclaim or harvest energy available within the same plant or building. Chillers and cooling plant used to cool manufacturing processes and facilities generate heat that typically gets lost to atmosphere. This heat can be harnessed effectively by industrial free heating (i-FH) units.

ecarbonisation of heavy industrial processes is central to reaching the Government’s target to achieve net-zero greenhouse gas emissions in the UK by 2050. But where and how to start? A consultation with experts ensures an informed start. Whether you’re considering a new system or planning to upgrade the existing one, work closely with an expert partner capable of designing or redesigning your cooling and heating systems, someone that could then remain as your service provider. This opens the door to equipment tailored to your needs and generates opportunities to enhance your temperature control process and HVAC systems. To get a true picture of all areas that need to be addressed, the most comprehensive solution is to undertake an energy analysis audit. The audit records the existing energy use as well as usage patterns. It identifies opportunities for energy saving strategies, including technology replacements. Finding opportunities for energy, sustainability and efficiency gains in equipment in operation isn’t easy, and decisions on what and how to improve need to be based on hard data.

Innovative designs

While heat pumps were traditionally known for their residential applications, many industrial processes now look at heat pumps as an efficient heating solution for a wide range of processes, recognising the economic and emission reduction benefits.Heatpumps rely on one of the most energy-efficient methods of heating: the transfer of free thermal energy from outside to inside based on the difference in temperature between the two.

LEEDS CITY COUNCIL is leading a partnership of expert organisations in carrying out a feasibility study into the development of an innovative methodology for deploying domestic heat pumps at a highdensity within urban communities, in line with the UK Government’s ambition of installing 600,000 heat pumps a year by 2028.

RIELLO RX premix packaged burners are now available in outputs up to 3MW, offering NOx levels of less than 40mg/kWh, with high turndown ratios of up to 8:1, across a wide range of models. Riello RX burners feature a design that includes a patented woven wire gauze ‘sock’ covering the combustion head cylinder. Gas and combustion air are mixed upstream of the combustion head and then pass through precision-located ports and the gauze ‘sock’ to ignite on the external surface of the combustion head. This arrangement enables a very compact flame with a diameter directly related to the burner firing rate, ensuring precise heat control and optimum efficiency at all loads. The high turndown makes RX burners ideal for systems with variable heat loads where low NOx levels are also required. These range from condensing boilers through to process applications such as spray booths and industrial ovens.

Heat pumps and boilers combine to make savings at secondary academy

RX burners can be used in conjunction with variable speed drive motors to reduce electricity consumption and lower noise levels even further than the typical 30 per cent noise reduction compared to many other combustion applications.

The main design for the heating system allows the commercial heat pumps to provide the bulk of the heating and hot water throughout the year for maximum efficiency, energy savings and minimal emissions. To ensure efficiencies do not suffer once outside temperatures fall below a pre-defined setpoint, the THISION L ECO condensing gas boilers provide back up. Commenting on the project objectives, Andrada Borcovici, low carbon consultant for Surveyors to Education, said: “Following a successful Phase 1 Public Sector Decarbonisation Scheme application, funding was received by the academy to undertake the fabric first roof insulation restoration works, and install a highly efficient and low carbon air source heat pump heating system. This forms part of the academy’s successful Low Carbon Skills Fund application and its long-term decarbonisation plan.”

The six versions offer circulating air or supply air heating/cooling, each with two output sizes, thereby covering all requirements. Different device types can be combined with each other, thereby extending Hoval’s well established zone-based control concept.

The inherent flexibility of the units enables even further customisation to meet project requirements. For example, through optimised control functions, outside air can be used for free heating and cooling when external temperature conditions allow. A further benefit is that if the layout of the space below is changed it is very straightforward to reconfigure the ventilation units to ensure optimum performance is maintained.TopVentdecentralised systems ensure that each space – or each zone within a large space – can be controlled independently of other units in spaces/zones. In this way, different activities, variable occupancy patterns and changes in usage are all addressed. ■

When a secondary academy received funding to replace its ageing heating plant, ELCO Heating Solutions was on-hand to supply a new, highly sustainable hybrid system. By combining two 48kW AEROTOP M commercial heat pumps with two 120kW THISION L ECO wall-mounted condensing gas boilers, staff and students are now benefitting from the latest heating and hot water technology. Plus, the project is contributing to a combined carbon saving of 134 tonnes per year.

The new equipment has replaced two coal-fired ‘Robin Hood’ boilers, which provided heating and hot water to the premises for many years. With poor efficiencies and the need to be stoked every morning, the academy required a new system that was going to be fit for the future and provide longterm sustainable heating and hot water production.

HOVAL has launched a new range of TopVent decentralised roof ventilation units, specifically designed to meet the needs of modern logistics operations, production halls and retail ‘sheds’.

Building on the popularity of the tried-and-tested TopVent units, this new range is especially suitable for applications where undisturbed operation within the building is of paramount importance.

To that end, the new units are installed completely from the roof onto prefabricated roof sockets and prepared roof ducts. This means that the only work required in the building is hydraulic and electrical connections.Moreover,all serviceable components can also be accessed from the roof, so that regular maintenance and service work can be carried out without disturbance to the activities below. Thus, maintenance is easier to schedule and downtime is avoided.

Control options include progressive two-stage operation and fully modulating via 0-10V or 4-20 mA. Full electronic control with operational and diagnostic display is also available. ■

The new AEROTOP M reversible heat pumps are available in outputs from 24kW to 48kW, and all models supplied with flow and return manifolds for arrangements of up to four heat pumps, while 16 units can be managed by a cascade controller. The AEROTOP range also extends to ‘L’ models which can deliver outputs from 54kW to 88kW. ■

The first requirement of the project was to connect the building to the gas mains. Once the connection was completed, the main contractors for the project, West Midlands-based BSN Group –was responsible for works, including updating the heating system. James Robinson, senior contracts manager at BSN turned to ELCO’s area sales manager, Brett Stokes, to help plan the project and provide a technical submission for the integration of the new heat pumps and boilers.

Due to the sensitive location in the heart of London, the project was logistically challenging, and involved tight space limitations due to the restricted rooftop location for the chillers.Thechillers are connected to the building management system, providing high-level control and monitoring and enabling optimisation of performance. In the unlikely event of a fault, the chiller compressor does not switch off, but continues to operate with reduced capacity (unloaded mode), ensuring continuity of cooling to the building while remedial action is taken. As the building’s HVAC services had been developed over time to meet changing needs, phase two of the project involved reconciling existing systems with the new Carrier chillers, to deliver a unified, modern system that fully meets current needs.

lighting. To meet the demands of a state-of-the-art and future-proof office building, it must be convincing in terms of efficiency and quality of illumination and luminaire design. Here, too, Up! sets new standards. The lighting concept was conceived by the renowned lighting design firm Licht Kunst Licht, which was named Germany’s ‘Most Innovative Lighting Design Company’ in 2020. The task was to illuminate approximately 65,000m from the stairwell to the executive office. The luminaire of choice for the entire building was the TRILUX E�LINE NEXT LED continuous row in stylish black. Thanks to its modular design, the luminaire adapts to the various application areas in the building.

A major refurbishment of London’s iconic 111 Buckingham Palace Road, located near Buckingham Palace and Victoria Station, includes a new air conditioning system with highefficiency Carrier screw chillers. Tenants occupying the landmark building now benefit from outstanding indoor comfort provided by two CARRIER AQUAFORCE 30XBE aircooled chillers, installed by Leonari Ltd for Savills’ consultancy division. Delivering a combined total of 2.4MW of cooling, the chillers are equipped with variable speed fan motors to minimise noise levels and maximise energy savings, delivering a seasonal energy efficiency ratio (SEER) for cooling of up to 4.6.

What does one do with an ageing department store in an attractive Berlin location? Transform it into a state-ofthe-art office location. This happened to the former German Democratic Republic (GDR) Department store Centrum in Friedrichshain, Berlin. The architectural conversion resulted in Up! At the top of the to-do list was to bring more daylight into the interior. Four ‘slices’ were cut out of the monolithic facade, creating a stepped fascia effect that generated more exterior glazed surfaces (by more than a third) to maximise natural light. Now daylight bathes the central areas of the building and there is more space for outdoor terraces on each floor. A central building block and a styledefining element in the interior is the Conversion to offices aided by LED lighting Worthington as the central hub the building now houses a new spacious food court, the Student Services Centre, and is home to the Student Union. The main challenge was introducing an energy-efficient LED scheme with a lighting control system to meet the architect’s original concept to a tight deadline and within budget. Various energy efficient Zumtobel and Thorn luminaires were selected for the workspaces and circulation areas. These included Zumtobel’s PANOS infinity, PANOS evo, TECTON, SLOTLIGHT infinity, VAERO, ECOOS, NIGHTSIGHT, ONDARIA, SCONFINE, COMSIGN and Thorn’s Omega LED, Chalice Pro, Chalice, and IQ WaveTheSuspended.PANOSLED downlight series is ideal for the functional and architectural lighting tasks for education settings.

On the road to net zero, a plethora of reports and surveys highlight the current shortage of skills within the energy sector. According to a recent report from an international consultancy, it is estimated that the UK faces a shortage of hundreds of thousands of skilled workers required to make the energy transition happen and support the UK Government’s net-zero targets. This covers a range of areas within the full spectrum of the Management

Produced in Association with energy sector such as renewables, hydrogen, energy storage and energy management.Energymanagement inevitably sits at the heart of the energy transition. It comes as no surprise that one of the key findings of this year’s Energy Barometer (the Energy Institute’s (EI) annual report that outlines the responses of hundreds of energy professionals who represent views across the UK energy sector) is that energy efficiency is ranked as the most important medium and longterm response to tackling the current energy and climate crises. Clearly the cheapest and cleanest form of energy is energy not used in the first place. Energy efficiency is the first fuel of economic development and the skilled professionals who know how to realise its benefits will be leading the global low carbon transition. According to the International Energy Agency, 40 per cent of the emissions abatement required by the Paris Agreement could be delivered by energy efficiency. Broad range of skills Energy management is a very commonly used term. It can be defined as ‘the proactive, organised and systematic coordination of procurement, conversion, distribution and use of energy to meet an organisation’s requirements, taking into account environmental and economic objectives’. This definition illustrates the broad range of managerial and technical skills modern energy managers are required to gain, to be able to improve the energy performance of their organisations, by reducing energy waste and identifying energy saving opportunities. The role has changed dramatically over the years. What was

This leadership training can be viewed as the energy manager’s MBA and is intended to strengthen skills, inspire and encourage delegates in their current and future roles. Whether you chose to in enrol onto formal training, self-learn, learn from others or to read books here are top 10 leadership skills to develop in practice.

On top of this, energy managers need to have strong leadership and strategy planning skills as they act as the enablers of an organisation’s net zero pathway. Setting up and implementing clear strategies as far into the future as possible will help provide a structure that ensures everything is produced to meet deadlines for reporting, presenting business cases, ensuring compliance with regulations/legislations etc.

SERIES 20 / Module 03

Energy managers’ natural strengths lay within areas such as numeracy, project management, the management of contracts and are usually also comfortable working in traditional ‘hard’ business areas. However, in the current business climate energy managers may also need to develop additional skills in areas of sales, marketing, strategy and other ‘soft’ business areas.

A leader acts as a bridge between staff and senior management and translates higher level strategies and goals into operating plans that drive the business.

The energy management training portfolio is developed and delivered by leading experts with vast practical experience.Asenergy management is such a dynamic field, constantly evolving and expanding to cover broader skillsets, the EI’s training portfolio is regularly updated to align with the latest developments in technology, best practice procedures and policies.

EIBI | SEPTEMBER 202226 used to be considered predominantly a technical role, now incorporating a range of crucial managerial and soft skills such as project management, risk assessment and communication to name a few.

To be a leader is to be a person who is responsible for controlling or administering an organisation or group of staff, resources, projects, and tasks.

Driving the business

Association with

The key role of a leader (see fig. 1) is to: ⬤ establish vision, mission and values - for the organisation to follow; ⬤ set strategy - guiding the organisation’s direction of travel; ⬤ implement and delegate - either during the task or delegating to others; ⬤ monitor how junior management is carried out; ⬤ stakeholder management - to

As a result of the crucial role energy management holds as part of the energy transition, training in energy management is more important than ever.

The most recent update of the EI’s energy management training structure involved the redesigning of the Level 3 ‘Advanced Energy Manager’ training qualification. This course is designed for experienced energy managers. Due to the requirements of the energy transition, the focus of the content has an energy manager and an energy leader, and the key skills needed by energy managers in this current, and at times challenging, business environment.

Training framework

The EI has developed and designed a comprehensive energy management training framework, aiming to support professionals throughout their careers from the point where they might seek to enter the sector, to gaining chartered status. It is divided into three training qualifications (Level 1, 2 and 3), which teach delegates: ⬤ the knowledge and skills required to manage energy use on a daily basis; ⬤ how to identify energy saving opportunities across a range of technical areas; and ⬤ how to make, communicate and implement effectively strategic decisions and influence an organisation’s policy through demonstrating their leadership skills.

A real-life project component is also included – the project is required to cover a strategic angle asking delegates to set a medium- to longterm strategy for their organisations. In addition, delegates are required to present their project to an assessment panel made up of course tutors. This is intended to provide the participants with experience in presenting and selling a project proposal to decision makers.Thefollowing three paragraphs provide more information on the importance of modern energy managers gaining leadership qualities in the current landscape and act as an introduction to key leadership concepts and tips. In the current world of high energy prices and climate change mitigation, energy managers increasingly are being required to transition into dynamic leaders. They are required to bridge the gap between staff and senior management and translate higher level strategies into operating plans that drive the business. Let’s look more into the key differences between

The key role of an energy leader is to direct their organisation and employees to the established ‘vision, mission and values’. This means being clear with all the relevant parties about acknowledging where you are trying to get to, why you are doing what you are doing and how you are going to go about it is an essential part of developing a strategy - The role of any leader should begin with establishing or understanding an organisations vision, mission and values. When considering the ‘vision’ of the organisation you should refer to its values and its ideal future state. For example, this should consider how the organisation is to become the best, most innovative, disruptive or lowest cost product and service. There may be many drivers for an organisation to include in its ‘vision’.

The implemented schemes usually focus on the medium to long term (three to five years), but it can be reliant on the short term too – you can’t accurately predict when and how things will change, so the strategy has to be flexible, and so does the energy manager.Organisational strategies are often developed ‘top-down’ but increasingly organisations seek to mobilise and motivate a greater number of employees by involving them in a strategy’s early development. Because of this energy managers need to be capable of finding ways to creatively integrate top-down and bottom-up forms of strategy within their organisation.Asyoucan see from the above, we have so far considered mission, vision and values and strategy at a high level and there are many more aspects to consider in becoming a leader. It is for this reason that the EI’s Level 3 Advanced Energy Manager course includes a two-day focus into leadership for energy managers. This course includes four essential modules in leadership training. ■

For example, a PV manufacturer may set its vision as: “to develop photovoltaics that achieve 50 per cent installed efficiency”.

⬤ Conduct strategic reviews ⬤ Understand where true ‘value’ is created in the business or service ⬤ Prepare organisation mission, vision and values ⬤ Exercise entrepreneurship ⬤ Plan for innovation ⬤ Practice product and service development ⬤ Engage with stakeholders ⬤ Exercise accountability ⬤ Seek feedback ⬤ Act Transparently Top DevelopSkillsLeadership10to

Opportunities, possibilities Energy managers increasingly are being seen as a means of mobilising an organisation to new opportunities and possibilities. One of the key approaches to increasing an organisation’s prospect in this way is by implementing a strategy. A good strategy will aim to determine how an organisation will match its diverse capabilities with the needs of stakeholders, now and in the future, to maximise its impact.

EIBI | SEPTEMBER 2022 27

Overall, the focus upon the creation of value can be very powerful and benefit organisations in, attracting investment, customers and motivating employees. So, for the PV example to incorporate their values into their working strategy and vision, they could include that they could aim to ‘only consider materials that are 100 per cent recyclable.’

SERIES 20 / Module 03

Training for Energy Management in Association with ensure internal and external stakeholders are considered and managed; and ⬤ risk management - understanding and management of risk.

An organisation’s strategy will also try to determine how it relates to the outside world – how it makes the most of opportunities, responds to change, and faces up to threats: opportunities to innovate, improvise and improve. In summary – a strategy makes it clear what the priorities are, what its gaps are and how the organisation’s resources should be concentrated on overcoming these gaps and delivering.

Produced

The mission is what needs to be done to achieve the desired state of the organisation.Usingtheprevious vision for example it could be: ⬤ to invest in research & development and in new materials; ⬤ form partnerships with specialist universities; and ⬤ to make a breakthrough in PV efficiencies. However, this does not consider the values of the organisation. Organisations should exist to create value for their customers. This can be to fix problems, frustrations, make life easier or to innovate in ways nobody thought was possible. Successful value creation should be held in balance between customers, shareholders, employees and other key stakeholders.

he month of August is traditionally a quiet one with holidays on everyone’s mind. During the pandemic that changed but we now are back in the old ways. As someone who has worked with Governments across the last twenty plus years, I have been used to the long holiday that Parliament takes. What I have most certainly not been used to is what happened during this August and has finally been concluded – the election of the new Conservative party leader who, by default, is the next Prime Minister.

Now that we finally have a new Prime Minister, it really is time for Government to get a firm grip on the energy crisis with firm policies, says Mervyn Pilley T

Executive director of ESTA (Energy Services and MervynAssociation)TechnologyPilley

Interestingly, while putting forward his potential plan for tackling the crisis, Stephen Fitzpatrick, founder of OVO Energy, referred to a national obsession with energy efficiency. We are fully in support of this idea. There has been earlier discussion about creating a heat pump installer army and we are absolutely in support of creating an army of energy efficiency evangelists.

It is a huge shame that energy efficiency has not been front and centre in government policy, especially with a properly funded national retrofit strategy. If the required work had been conducted consistently across the last twelve years, then we would not now be standing at the bottom of a mountain peering up at the top and wondering how we are going to reach the top. Lost opportunities that will make the job far harder to achieve. Our mission to bring behaviour change to the sector at scale through the EnCO programme continues. We have been disappointed by the response from various ministries who are struggling to understand the low-cost/fast pay back aspect of injecting behaviour change into the energy efficiency mix - the importance of matching human with technology. Unfortunately, BEIS have a track record of not wanting to tell people how they will need to change their lives personally so that the UK can reach its legal targets. I say BEIS, but the outgoing Prime Minister made it very clear in his introduction in the Net Zero strategy published last year that the Government doesn’t believe that good advice and education needs to be delivered to people and that everything should be down to the individual’s choice.

primarily but not only, due to energy costs have given business a stark choice – increase prices to customers and risk a major drop in sales or reduce costs by shuttering buildings or losing staff.

days, we used to help Governments formulate policy but in the last fifteen years or so Governments have tended to approach the major businesses direct to get policy ideas. This has often disenfranchised many businesses and their trade bodies. Trying to lobby a government that is failing to listen or not able to listen while a new leader is being chosen is frustrating.

National retrofit strategy

The election process, which is the first time that a new PM has been elected purely by the members of one party, has thrown up the worst possible scenario of a total vacuum of policy development and introduction in critical issues. The world is in crisis and the UK is very badly positioned to work its way out of what looks like a recession on the way. A combination of factors - some like Brexit self inflicted - and others like the Ukraine war are inflicted by others. They have combined to put UK businesses between a ‘rock and a hard place.’ Exceptionally large cost increases,

Not getting the message

My major frustration remains how, even with energy price levels as high as they are, not enough companies are getting the message about the importance of using less energy and managing the use of energy. As membership spend is discretionary it is even more frustrating that member recruitment has continued to prove frustrating due to cost pressures.

We now know that Liz Truss is going to be leading the UK, potentially for the next two years unless an early election is called. In the campaign between the two rivals to be prime minister so little detail has been given about what would happen on day one to tackle the energy crisis, and crisis it certainly is. Various plans have been floated by a range of parties. Much has been said about the role of Ofgem and how

The major problem with that approach and indeed something that was borne out by a certain referendum that took place in 2016 is that unless the public is well educated on all of the implications it is really not safe to leave critical decisions around the future of the planet in their hands.

Worst possible scenario

From wholesale prices to kWh on the meter, data can be used to inform and manage every aspect of energy from source to use. By monitoring real-time energy data, energy managers can see how much energy is being used, the cost to the business, and ultimately what can be done to reduce consumption and cost. By reviewing trends and insights, it’s possible to determine the most efficient way of managing energy usage, whether they’re responsible for just a couple of premises or a large, global portfolio.

Most businesses have a wealth of data, but how it’s used is critical. Ben Rouncefield-Swales urges businesses to make data a priority to mitigate rising energy costs

Advancements in software Recent advancements in softwareas-a-service (SaaS) technology have made it easier than ever before for businesses to harness accurate and automated data management and reporting in a more affordable way. This far more flexible methodology has replaced dated strategies that might once have required an entire CapexToday’sprogramme.systems are more agile and able to accommodate rapid industry changes, making data collation and optimisation effortless and more economical than ever. Advances in technology have also meant that it is much simpler to integrate this technology with other software, such as smart buildings. By combining data collected from a range of sources and sensors, building owners can build a comprehensive picture of energy usage and emissions from source to reporting. Overall, it is becoming increasingly difficult for businesses to operate without data as a priority, and soon it may very well become impossible. As sustainability reporting frameworks and standards become more stringent, businesses that choose to invest in accurate and automated data management tools are saving significant time and effort whilst reinforcing themselves against the volatility of today’s energy market.

it’s no longer possible to wave away questions about how businesses can continue to function in a net-zero world. Those holding the purse strings want to see accountability through data, and they want to see real action. Even significant investment firms, such as Larry Fink’s Blackrock, have begun to ask potential investments to prove how their business can exist in a net zero world, not just with empty promises but with hard data as evidence. According to PriceWaterhouseCoopers, 80 per cent of investors say that Environmental and Social Governance (ESG) is an important factor in their investment decisionmaking. More damningly, 50 per cent claim they’d be willing to divest from companies that didn’t take sufficient action on ESG. Last year, it became mandatory for commercial businesses with a UK premium listing to report their ESG data to the Taskforce on Climaterelated Financial Disclosures (TCFD) and it’s anticipated that these expectations will only grow in scope over the next few years.

With accurate data organisations can see peaks and troughs of energy use

On a grander scale, data is also crucial in helping organisations meet the increasing demand for accountability in emissions. Whether from the Government or investors,

Data is the hidden hero

■ A s we all face the challenges of a volatile energy market, it has never been more important to take control of how we use and manage energy. We all know that harnessing the power of data is crucial, but with a plethora of data available across multiple sources, collating, optimising and organising that data can be a resource-intensive task. And as we become ever more sophisticated in our building and portfolio management, creating clarity from data complexity deserves realDatafocus.isa fundamental part of not just emissions reporting, but developing strategies and implementing ways to create and nurture a more sustainable business. More important, however, is ensuring the accuracy and integrity of that data from the off to ensure its usefulness. Data is everything. The world we live in is informed by, and functions on data, and nowhere is this more obvious than when it comes to energy.

justifiably more focused on the hereand-now. Skyrocketing wholesale energy prices are a real concern as businesses begin to feel the pinch of an unstable energy market. Data can help here, too. By improving data accuracy, businesses can see the peaks and troughs of where energy is being consumed down to the penny. This enables them to take real action to control energy spending and make significant savings in the long run. Smart buildings have an important role to play. Monitoring data across buildings and assets helps businesses to compare and contrast energy usage accurately, and more easily target the areas where consumption is highest. It can also help to control and optimise consumption, automatically reducing during peak demand periods to support grid balancing. Not only is this better for the environment and the push for net zero, but it will also help protect against the volatile nature of today’s energy market.

As technology continues to evolve, there is an increasing focus on the wellness of individuals in the workplace, as well as the drive for smarter buildings which help boost productivity.Withflexible working becoming more common it is important that businesses make their places of work appealing to work in for their staff when they are not working remotely. Workspaces that are clean, comfortable and safe are obvious requirements for any business that wants to attract the best staff. Employees who feel comfortable in their workplace are generally more motivated and more productive than those who feel that their work environment falls short of expected standards.Thelatest advancements in technology allow for smart building controls systems and sensors to be installed, which enable users to optimise their working environment.

SMART BUILDINGS

The BCIA has previously highlighted how the lockdown periods in the last couple of years have cast a spotlight on the issue of building performance and efficiency. With many commercial buildings suddenly left unoccupied we were provided with a real insight into how unprepared many businesses were in terms of managing their premises efficiently. In the age of corporate ESG (environmental, social governance) it was also a wake-up call for many organisations realising just how far behind they were in their environmental credentials and commitments to sustainability.

for a company’s behaviour used by socially conscious investors to screen potential investments. Environmental criteria consider how a company safeguards the environment, including corporate policies addressing climate change, for example. Social criteria examine how it manages relationships with employees, suppliers, customers, and the communities where it operates, and governance standards ensure a company uses accurate and transparent accounting methods, pursues integrity and diversity in selecting its leadership, and is accountable to shareholders. From an environmental perspective, in a true smart building, if the technology is correctly designed, installed, commissioned and maintained it can help reduce energy consumption and spend and in doing so reduces carbon emissions. Companies can also provide the measurement and report the data to be able to illustrate their case to corporate shareholders. Expect better conditions From the social angle, in the 21st century it is perfectly reasonable that we expect better conditions in the buildings we occupy.

Graeme Rees believes this summer’s heatwave has underlined the increasing value of smart buildings in terms of occupants’ comfort and environmental sustainability.

The unprecedented situations we have found ourselves in the past year or two have certainly galvanised the issue, but the ability to manage, adapt and interact with our buildings is important at any time, not just during a pandemic or an excessive heatwave.

EIBI | SEPTEMBER 2022 35

Not only is the technology going into buildings improving, but the ways in which both a facilities manager and its occupants can connect with their buildings are becoming simpler through the development of smart building software and apps. A smart building app can bring together all the smart features of a building, such as occupancy monitoring, temperature monitoring and energy monitoring and make the information available instantly on a smartphone or tablet.

ESG criteria are a set of standards

The adoption of online meeting platforms such as Zoom and Teams meant important discussions could still take place without the need to meet up in person and online meetings are becoming more common as we are perhaps waking up to the fact that driving to a meeting is neither environmentally friendly nor financially justifiable in many cases. But whether a space is sparsely or densely occupied, we have buildings throughout the country, old and new, that could be managed better, and the long-term benefits of investing in smart buildings is becoming clearer every day.

For the occupants, functions such as lighting and temperature adjustment, digital access systems and roombooking functions create a more userfriendlySustainabilityexperience.isa pivotal factor when creating and managing smart buildings, with energy conservation and CO2 reduction very much the longterm objectives of building controls.

A s the sun begins to set on the UK’s hottest summer ever recorded, do we need to place an even greater focus on the suitability of our commercial buildings in extreme temperatures? When temperatures hit 40°C in parts of the country in mid-July commuters were advised not to travel as rail networks operated reduced services, warnings were issued about the state of road surfaces affecting drivers and businesses asked some employees to work from home where possible to make conditions more bearable in their workspaces. However, none of these measures seemed as drastic as they once might have, as lockdown proved that employers and employees could carry on functioning effectively while working from home.

The climate clock is ticking. Given the enormity of the building and construction sector’s contribution to our collective carbon footprint, we need real-world solutions that make a difference today, and to focus our efforts on those buildings where we

Carbon-neutral operations have been achieved at the 6,600m² manufacturing site through a combination of digital solutions, electrification, and renewable technologies. This has reduced emissions by 636 tonnes. The site no longer uses any fossil fuels and uses recycled plastic as a raw material, reducing its carbon footprint by a further 106 tonnes a year. However, every ‘Mission to Zero’ is different. Building owners and operators are at different stages in their digitalisation and decarbonisation journey and may face a wide and varied range of environmental and financial considerations, all of which could delay progress⁸.

Digital and automation technologies are the answer for building operators looking to reduce emissions and save on energy costs, explains Bertrand Vandewiele can make the largest impact in the shortest time. Our facility in Porvoo, Finland – part of ‘Mission to Zero’, the company’s energy self-sufficient blueprint for industry, homes and cities – is a real-world example of how digitally networked and controllable systems can help enhance energy efficiency and play a vital role in the fight against global warming⁷.

Combination of solutions

Partnering with the right technology provider at the outset of a project’s evolution helps plot a smoother course of action, based on best practices, lessons learned and implementing tried-and-tested costeffective solutions. By sharing the experiences of technology partners, customers and employees, building owners and operators can benefit from the full breadth and flexibility of digital innovation. If the building and construction sector works together in true collaboration to reduce its carbon footprint, powered by AI and smart technology, great strides can be taken towards a cleaner, safer, more sustainable world. ■ T he building and real estate sector has a vital role to play in limiting energy use and related greenhouse gas (GHG) emissions in line with the 2015 Paris Agreement and Glasgow Climate Pact goals. While this is no small challenge, industry, construction companies and building and facilities managers do now have access to a new generation of ‘smart’ digital technologies. When these are combined with advanced data analytics, they give far greater insight and control over every element of a building, unlocking opportunities to saveImplementingenergy. central and automated controls can have a major impact on energy conservation and waste reduction. According to the American Council for an Energy-Efficient Economy, building owners and operators that invest in smart automation frequently report decreased energy costs of up to 50 percent¹.Artificial intelligence (AI) can optimise data collected by interconnected devices, for example.

Overall, this can add 50 percent to the lifecycle of HVAC equipment. Our solution with BrainBox AI solution is currently used in approximately 9.3m/m of commercial real estate, including shopping centres and office buildings in Australia and Canada.⁶ The scale of its energy saving potential is huge.

The upside of AI-enhanced climate tech is that it can be rapidly and widely deployed to have a major impact on decarbonising several sectors, particularly when it is used to reduce energy consumption.

Partnering with the right technology provider will bring benefits to end users with various systems. Smart sensors can then adjust light, oxygen content and temperature based on user preferences. Similarly, armed with data on how efficiently the facility is operating, managers can optimise energy use, reduce emissions and make cost savings.

Capgemini Research Institute reports that AI is likely to have reduced overall GHG emissions by 16 per cent by 2030 and estimated to have helped organisations hit up to 45 per cent of the Paris Agreement targets².

Our latest breakthrough in reducing energy costs and carbon emissions from HVAC systems is being achieved by partnering with Montreal-based innovators, BrainBox AI – enabling us to combine our digital platform for buildings and BrainBox’s predictive, self-adaptive, and scalable cloudbasedThroughAI. this collaborative solution, existing HVAC equipment can be upgraded with predictive algorithms that eliminate the need for human intervention. In addition, it monitors, analyses and reports to help track energy efficiency. Legacy HVAC systems can be easily upgraded with this technology and has the potential to reduce carbon footprint by up to 40 per cent⁴, energy costs by as much as 25 per cent⁵ and improve occupant comfort by as much as 60 per cent.

messages of doors and windows. In office blocks or infrastructure buildings such as railway stations or airports, they enable maintenance and repair work on lifts, heating and air conditioning systems or any other technical equipment to be carried out as required and thus more efficiently. For this purpose, they send certain status messages via an IoT gateway over the internet to the relevant service provider.

Networked with IoT platforms, the sensors provide real-time data for the digitisation of buildings and building services.

T he IoT has found its way into commercial buildings. Radiobased lighting, heating, and security systems as well as new types of services provide more comfort, more efficient and better building services, and lower energy consumption. The energy supply for the wireless sensors that collect the needed data usually comes from batteries, which is not optimal for severalAlthoughreasons.battery replacement is a relatively fast process, travelling to the site, locating the battery, testing the device, and documenting the process all dramatically increase the labour costs. In addition, conserving resources and protecting the environment are equally important factors when it comes to sustainability: the prices of raw materials such as copper are steadily rising, and the harmful components in batteries present a growing problem as well. EnOcean chooses a more sustainable method for its wireless sensors: they obtain their energy from movement, light and temperature differences according to the principle of energy harvesting and require neither cables nor batteries for

The use of a building can also be optimised in this way: presence and activity sensors can record how often a meeting room is used by how many people. The same applies to sanitary facilities, so that they can be cleaned as required and consumables such as toilet paper, soap and towels can be refilled. This reduces effort and costs while at the same time increases user satisfaction. The facility manager in turn can be sure that the agreed services have been provided.

North west factory to hit carbon neutrality eight years ahead of target

Combined with reducing waste to landfill to zero and EV charging for staff and visitors, the Cheshire site is eight years ahead of Siemens’ original 2015 commitment to ensure carbon neutral operations by 2030. Commenting on the achievement, Andrew Peters, managing director of Siemens Digital Industries Congleton, said: “Siemens believes that sustainability is a force for good and can deliver value for all its stakeholders. We want to help customers achieve sustainable growth and to transform their industries through decarbonisation. The first step of that is for us to achieve these ambitions in our own operations.”The50-year-old Siemens Congleton factory began its sustainability journey in 1990 when it began manufacturing drives to meet the demands of industry. In 2018 the factory became fully digital by embracing lean manufacturing methods to achieve continuous improvement and by adopting leading-edge Industry 4.0 processes. Using advanced manufacturing methods include Virtual Reality, Digital Twin, the Industrial Internet of Things (IIoT), Advanced Robotics, Cloud Technology and Additive Manufacturing, it has mastered producing up to 50,000 variations of its products to fulfil the shifting demands of its customers and markets, increased productivity by driving down costs, and improved efficiency. In 1990, 400 workers made 50,000 variable speed drives and controls a year. Today, a similar number of workers produce 1.2m electrical devices - including 600,000 variable speed drives (VSDs). What is more is that it has been achieved within the same physical footprint. The factory is bounded by industrial units and housing estates, with no room to expand, meaning Congleton has one of the highest productivity rates per m² of any Siemens’ sites. ■

Utilising Contemporary Controls’ BASautomation Series of opencontrol BACnet/IP Controllers, PBH Mechanical Ltd was able to complete their project on time and deliver an automation system that exceeded their client’s expectations.PBHMechanical Ltd performs installation and maintenance management of building controls, such as HVAC and plumbing. The application was to operate actuators for 26 windows based on combined ambient temperature and CO₂ level per designated zone. Programmable windows are one component of an intelligent building automation system. Room climate automation can improve indoor air quality and provide a healthier and more comfortable working environment for employees. In addition, room climate automation saves energy and reduces operation costs.The controller was to be fully programmable and contained within a wall-mounted control panel (800 x 800 x 200mm) in the IT room. The controller was to operate 26 windows actuators located in nine mechanical zones. Each zone contained an open/close rocker switch, 1,200mm above finished floor level (AFFL), and a temperature and CO2 sensor 1,500mm AFFL.

SIEMENS’ Congleton factory is on track to achieve carbon neutrality this yeareight years ahead of its original target. The operation, which manufactures more than 1.2m controls and drives each year, is inching its way to the major milestone after deploying a range of sustainable solutions for energy generation and demand with support from Siemens’ energy and performance services business, SmartTheseInfrastructure.includegenerating 75kW of renewable energy through a hydroelectric plant at Havannah Weir on the river Dane and using carbon neutral, certified biogas to power its on-site gas engine. These measures alone saved over £250,000 pounds a year and took the 80 per cent powerindependent factory off the grid. Beyond these innovations, Siemens Congleton adopted a building management system which automatically adjusts to drive energy efficiency improvements, while modern windows and LED lighting have reduced the total energy bill by 13 per cent and 30 per cent respectively.

Strict set of standards Environmental, social and governance (ESG) criteria are a set of standards for a company’s behaviour used by socially conscious investors to screen potential investments. Environmental criteria consider how a company safeguards the environment, including corporate policies addressing climate change, for example. Social criteria examine how it manages relationships with employees, suppliers, customers, and the communities where it operates, and governance standards ensure a company uses accurate and transparent accounting methods, pursues integrity and diversity in selecting its leadership, and is accountable to shareholders.

Fully behind net zero Another popular topic at the Round Table event was the UK’s net zero carbon emissions by 2050, the consensus being that most people are fully behind becoming net zero but have no real plan of action. Panellists agreed that there is a need for both behaviour and systematic change and that businesses need to address both old and new buildings with the same energy and enthusiasm to facilitate net zero. Furthermore, identifying the skills required while having skilled people in place to achieve these goals was deemed critical.

The show will host a busy conference programme, providing a vast range of thought-provoking content which has proved hugely popular over the years.

costs and the nature of the building itself. For instance, we were required to devise very different solutions for the Tate Modern (housed in a former power station), Tate Liverpool (a converted warehouse) and Tate Britain, which was designed as a gallery from the start. The components of the system will depend on the nature of the solution being applied. In most cases where RH needs to be raised, steam humidification will be the preferred choice and will comprise a humidifier to generate steam and a way of introducing the steam to the air. Where a ductwork ventilation system is in place the steam may be introduced to the air in the duct just after it leaves the air handling unit. In other situations, it may be more practical to feed the steam directly into the space being humidified.

All steam humidification systems will benefit from appropriate water treatment, typically reverse osmosis, to prevent limescale formation, extend the life of the plant and optimise efficiency.Analternative is to add water vapour directly into the space, which can be the most cost-effective and energy-efficient approach. However, given the nature of the spaces in question, humidifiers in the space are unlikely to meet the client’s aesthetic requirements. Wetted media above the ceiling avoid visual intrusion but or benefactors that are lending a piece to the venue. In the UK, most humidity problems relate to low RH, so that humidification is the most common requirement. However, there may be situations requiring dehumidification – perhaps even both at different times of the year. In all such cases, systems designed to provide the required level of control for the specific project are essential.

All such systems will also require strategically located humidity sensors in the space to achieve the required level of RH control. ■

Museums have to keep close control over precious works of art and delicate objects

For example, without humidity control wood will be prone to shrinkage (low humidity) and expansion (high humidity). This movement of the wood may cause cracking, separation of different wood layers and will also destabilise any paint or other finishes that have been applied to the wood. The finishes themselves may also be subject to deterioration when exposed to low or highMoreover,humidity.high humidity may result in potentially damaging condensation on metallic, stone or other objects with cold surfaces – and could also create a slip hazard on floors.

Such pressurised water systems ensure the water leaving the nozzles is quickly atomised (within 1.5m of the nozzle) and absorbed into the air, so there is no danger of wetting exhibits.

For instance, it is relatively straightforward to maintain a consistent environment in a storage area that is unoccupied for most of the time. In contrast, in areas where exhibits are on public display the RH will be influenced by the body heat and moisture-laden exhaled breath of the visitors – factors that may vary during the day as visitor numbers fluctuate.Consequently, systems serving areas with variable occupancy – or subjected to non-tempered air from outside for ventilation – will need to incorporate continuous monitoring by humidity sensors and be able to respond quickly to changes in RH. In all cases there will be a number of criteria to consider when selecting the best humidity control solution. These include capital budgets, running

In museums and art galleries swings in humidity can pose major problems to precious exhibits and works of art. John Barker explains how they can be overcome capital costs are increased by the need for ductwork and diffusers.

The impact of humidity on delicate works of art and other exhibits is well understood, so that many museums and galleries require close environmental control in both public areas and storage facilities. This requirement is addressed by BS5454, which specifies that relative humidity (RH) should be in the range 40-65 per cent (+/-5 per cent) and temperatures in the range 16-19°C (+/-1°C). Environmental conditions may also be dictated by insurance companies

As cold water is used, these systems are very energy-efficient and the evaporation of the water also provides some free cooling of the air. This can help reduce the use of mechanical cooling in the summer, though may result in a slight increase in heating requirements in the winter.

Appropriate water treatment

For short-lived exhibitions/displays there are also temporary solutions available, such as evaporative coolers that blow air over cellulose evaporative panels to release water vapour into the recirculating air.

museumatControlthe

A more discreet option is to install small, multi-directional fan-assisted nozzles – around the size of a CCTV camera – at high level in the space(s).

Consistent environment

The nature of buildings used as museums and galleries varies enormously so it follows that the best humidity control solution will also vary from one project to another.

Managing director of Humidity Solutions John Barker www.humiditysolutions.co.uk

ome minor fluctuation in environmental parameters such as temperature and humidity is generally not a major problem in most indoor environments. In museums and galleries, however, even quite small fluctuations can cause significant damage to arts, antiquities and other delicate objects.

In spaces where dehumidification is required, the preferred system is generally a desiccant dehumidifier, optionally with heat recovery to reduce energy costs.

As the water is not heated, there is a need for anti-bacterial treatment, such as ultra-violet treatment.

Humidifiers supply the optimum levels for meat maturation rooms

MUNTERS has supplied three MLT800 desiccant dehumidifiers to Fairfax London to create the optimal relative humidity levels for their meat maturation rooms. Part of Fairfax Meadow, Fairfax London opened a purpose-built facility in 2018 complete with maturation rooms dehumidified by Munters. “When we designed this depot, our focus was to have a state-of-the-art maturation facility with a Himalayan salt wall. This would enable us to create the best possible premium dry-aged beef,” said Rob Shears, head of sales at FairfaxMuntersLondon.recommended an MLT800 desiccant dehumidifier to dry age the beef in what became the first of three maturation rooms. “Each customer has their own, unique set of requirements to create their perfect climate, and here we suggested somewhere between 0-2°C, and between 50-80 per cent relative humidity,” says Glen Wilson, senior sales engineer forLessMunters.than six months later, demand for the dry-age beef had doubled and the maturation room was filling up. This substantial growth was attributed to the superior quality of the meat, and the precise conditions in which it is aged - thanks to the Munters desiccant dehumidifier. After acquiring a key client in premium casual dining, Fairfax London ordered another MLT800 desiccant dehumidifier for their second maturation room which, like the first room, quickly filled up. “There’s no point in having two rooms at full capacity,” said Shears. It was at this point that a third MLT800 was purchased for room number three, which was delivered and installed in time to cope with the increased demand. With three maturation rooms in high demand, Fairfax London has been able to significantly increase production and bring on board additional clients that they wouldn’t have previously had the capacity to work with. By combining the right product, with the right facility, temperature and relative humidity levels, Fairfax London is able to be a leader in this product category. The maturation rooms have helped them become an Agriculture and Horticulture Development Board (AHDB) Top Tier supplier of premium dry-aged beef.

The evaporative humidifier incorporated into Weatherite’s Adtec-D is based on the standard Condair ME, but with some modifications to meet the project requirements. This project is an example of how Condair can develop innovative and flexible solutions for its customers. ■

Dave Marshall-George looks at how free-air and evaporative cooling systems provide year-round cooling for telecoms and data centres

EIBI | SEPTEMBER 202246

iven the huge and ongoing rise in the cost of energy, organisations that are high energy consumers, such as data centres and telecoms facilities, are suffering greatly. There has never been a better time for these types of operations to consider more energy-efficient cooling alternatives to DX chillers, such as free air cooling systems. The UK climate and the warmer than average conditions accepted in these facilities, means this type of cooling strategy is perfect for DC and telecoms buildings. A free-air cooling system uses the outside air to cool the internal environment for most of the year. Then during the hotter months, evaporative cooling is also employed to enhance the performance and meet the required cooling load. This strategy has been proven sufficient to meet the needs of UK data centres and telecoms buildings, even during the UK’s hottest day recently experienced in July 2022.

The evaporative cooling technology, supplied by Condair, ensures the Adtec-D can maintain the allowable ASHRAE conditions, even during the warmer months in a European climate without the reliance on F-gas refrigerants.”“Weatherite only uses the highest quality components in its HVAC solutions, and this includes Condair’s evaporative humidifier. It certainly delivered on our specific requirements for operation, control and hygiene management, and we’ve been very pleased with the support offered by Condair in connection with this successful project.” Lewis concludes.

Free air cooling for data centres

Most modern data centres are now constructed using this type of cooling strategy, whenever their operating parameters allow. However, there are still many legacy telecom and data centre buildings that are using DX chillers to cool and suffering higher than necessary energy bills as a result. Retrofitting a solution into these buildings is of great importance, not only for cost efficiency but for environmental concerns.

Adtec-D has recently been able to fully replace DX mechanical cooling across more than 800 switchgear rooms for a leading UK telecoms provider. A total of around 1,500 Adtec-D units have been deployed in the project to date. A single legacy 30kW DX and free air cooling unit was consuming around 71,000kWh annually to maintain the required internal temperature, operating 24/7. The replacement 30kW Adtec-D cooling unit consumes just 14,000kWh to meet the same annual cooling load. This resulted in an 80 per cent energy saving for the West Midlands. Operating for over 50 years, the company provides a range of AHUs, heat recovery systems, packaged rooftop equipment and air cooledCondair’schillers.evaporative humidifier is providing adiabatic cooling in Weatherite’s Adtec-D free air cooling unit. The Condair ME boosts the cooling capacity of the system, allowing the Adtec-D to fully replace the need for mechanical cooling in some applications. Outside air used to cool The Adtec-D is a self-contained, modular cooling system that can be located either inside or outside of a building. In data hall or telecom environments, for most of the year it operates in free air cooling mode and uses the outside air alone to cool the internal environment. However, when the outside temperature rises to around 20°C, the Adtec-D switches to adiabatic cooling mode. The incoming air is then passed through the Condair ME, which evaporates water into the fresh air stream, cooling it by up to a further 12°C.

Andy Lewis, technical manager at Weatherite commented: “The Adtec-D is an ideal retrofit solution for telecommunications companies or data centre clients who wish to take advantage of free air cooling rather than continuing to operate DX chillers. Available in modules that can provide from 15 to 80kW of sensible cooling, the Adtec-D will typically operate with an energy efficiency ratio greater than 15, even at peak outputs.

T he recent heatwave has brought climate change sharply into focus. It is more vital than ever that the HVAC industry, whose products and services impact every industry, focuses not just on operational efficiencies but reductions in embodied carbon as part of the drive to reach the government’s 2050 net zeroHeatingtarget.and cooling in large and small buildings from office complexes to mission critical applications is estimated to account for around two thirds of industrial energy demands and approximately one fifth of the world’s energy consumption. These figures from the International Environment Agency (IEA) serve to highlight the need for environmentally friendly HVAC equipment. Globally, energy demand for air conditioning is predicted to triple by 2050 as the earth’s temperatures continue to rise each year. Every manufacturer, distributor and supplier has an ethical duty to ensure their activities, products and services do not cause more emissions.

Measure embodiedyourcarbon

Fan coil units (FCUs) are popular developmentBusiness manager at PaulAermecO’Gorman www.aermec.co.uk

The industry has long focused and are used in a wide range of HVAC applications. Cost effectiveness, flexibility, and ease of installation makes them a highly attractive proposition.Fancoilsare a sizeable market. As Europe's largest fan coil manufacturer, Aermec views the popularity and prevalence of cooling/heating terminal units, fan coil units (FCUs), and chilled ceilings that are used in a wide range of HVAC projects from commercial buildings to the hotel and leisure industry, as an opportunity to spearhead reductions in their embodied carbon.

AIR CONDITIONING

Paul O’Gorman explores how the design of fan coil units can lead the way when it comes to embodied carbon reductions in HVAC equipment

This provides an important starting point that empowers designers and manufacturers to identify and implement environmentally conscious strategies that benefit them and their customers financially. A FCU that combines the smallest weight with low operational energy and ease of maintenance would be an ideal solution; that’s exactly what Aermec’s new VEC-i fan coil unit does. The unit is a re-design of the traditional FCU that offers greater efficiencies and significant reductions in embodied carbon. This latest development in technology has taken the tried and trusted FCU to another level, believes Aermec. This new generation of smart fan coil units can be accommodated in standard size ceiling tiles, and easily networked. The unit provides total comfort thanks to a special air take and flow grid that enables a Coanda effect air flow that is generated parallel to the ceiling to provide optimal circulation in the space that is to be environmentally controlled.

Compromise efficiency From an environmental and financial perspective, it makes sense to maximise operational efficiencies. Aged units can compromise the efficiency of cooling and heating environments.Choosingsystems that use an EC motor over a conventional AC motor can undoubtedly reduce energy consumption, but what about noise, leaks, and maintenance costs? Although refurbishment may improve the overall efficiencies and running costs, there comes a point when full product replacement is the only option.Thefan coil industry has tried to keep pace with innovation by driving down energy usage. Developments have seen hybrid units come to market combining the benefits of chilled beams with FCUs. But technology has stepped up a gear with a newcomer on the block that is set to raise the bar; by combining the FCU’s embodied carbon materially and operationally without compromising on aesthetics.

CIBSE provides guidance as well as a methodology (TM65) that looks at the whole life cycle of products emphasising product weight and ease of maintenance as key variables.

Integrated EC fans gives Specific Fan Power (SFP) at 0.1W/l/s at 100 per cent load. Standard control operation with auto-fan speed control matched to load will give an average yearly SFP’s of 0.06 W/l/s, delivering approximately a 65 per cent operational energy savings versus standard fan coils.

EIBI | SEPTEMBER 202248

Don't ignore embodied carbon Embodied carbon affects all products not just chillers and air handling units but all other equipment where an Environmental Product Declaration does not exist. Businesses that put off or ignore the relevance of embodied carbon will be disadvantaged on many levels including financially.

Total system optimisation Operation with heat pumps with higher chilled water and lower hot water temperatures ensures total system operational energy optimisation.Theunitweighs 20kg to 32kg and offers good low embodied carbon opportunities compared to standard FCUs and chilled ceilings. The VEC-i unit generates 70 per cent material embodied carbon savings. When compared with chilled ceilings for example, their low cooling W/m² outputs need vastly more unit coverage whereas the VEC-i offers an 86 per cent material embodied carbon saving.Thebenefits are attractive and measurable, lowest embodied carbon, operational energy, low noise, operational comfort, ease of maintenance and lower installation costs.Bytaking a more pragmatic approach and analysing the embodied environmental impact of diverse types of HVAC systems, our industry can make significant changes to the landscape and the decarbonisation of buildings. ■

Aermec's latest FCU, the VEC-i is said to offer a reduction in embodied carbon attention on operational efficiencies of HVAC systems; energy and cost savings. But an approach that includes an analysis of the embodied carbon kgCOe emitted in the supply and manufacture of products and their materials over their operational lifetime (including their transportation) is being advocated by some trade associations. Whitehall is mooting regulatory requirements.

With home-grown power, we can import less and start focussing on realistic long-term strategies to reach net-zero 2050Tidalgoals.range power which can also produce green hydrogen, in my opinion, is the only avenue worth serious consideration. Our government plans to boost offshore wind capacity and increase investments in solar projects in years to come. It’s not bad news for the most part, but we cannot idly sit by and rely on these intermittent energy sources. Also, green hydrogen production is still impractically expensive because there is NO spare renewable electricity. Further investments and research are needed to make the production process more efficient. The potential is huge, but in the meantime, we must set up reliable tidal range infrastructure so that when we are ready for green hydrogen at scale, there will be renewable, off-the-grid power to spare. The UK hydrogen strategy aims to reach 10GW of hydrogen production by 2030, which aligns with my projections for tidal range. Our ‘power islands’ will be the leader in green energy and green hydrogen could take us into a new era of sustainable power if we are willing to take a chance and diversify our renewable energy sources. Ultimately, we can still have a future, or we can have gas and oil, but we cannot have both. ■

W e continue to rely on fossil fuels to fulfil the UK’s energy needs, and society is paying the price. Considering the unproven energy strategies and ambitious climate goals we have seen - I am never going to be convinced we are doing enough to limit carbon emissions to acceptable levels or at all. Gas, in particular, is a glaring obstacle in the path to net-zero, and we need to do something about this. Over a third (35.7 per cent) of our electricity was generated from gas in 2020. We cannot carry on like this. It’s thatMovingsimple.forward, long-term strategies to tackle our obsession with burning fossil fuels are needed. This means diversifying our energy mix and taking a long, hard look at all the different renewable energy solutions at our disposal. I believe tidal range power coupled with green hydrogen would provide an effective solution to the ongoing energy crisis. With this mix, we can break away from a growing dependence on gas and coal and add 24/7 renewables to intermittent wind and solar and therefore we will have base load renewal at our disposal. UK is well positioned The UK is well positioned to lead the way to a sustainable future for the global energy industry. More investment into innovative strategies will bolster domestic power production, helping to provide affordable, clean energy for our homes, workplaces and industry. However, prompt action is needed to tackle the spiralling global warming crisis.The UK is not as reliant on Russian gas as many other European countries. In fact, in 2021, only 4 per cent of gas used in the UK was Russian, a tenth of that supplied to Europe in the same year. That being said, we still imported a substantial 28 per cent of our gas in 2020 from the likes of Norway and Qatar, among other

Hydrogen is a carbon-free fuel source that can also act as a means to store energy, but it must be produced from renewable energy sources. As a result, it can help to tackle storage problems hindering the renewable energy industry. For example, it can alleviate the need for expensive batteries that put a strain on natural resources to produce. It’s a versatile energy source with multiple applications that can help reduce the carbon footprint of our energy industry if we can harness it renewably and at scale.

and it is on our doorstep as the UK has some of the world’s best tidal ranges.

Providing the base load

Tidal range has the potential to provide 100 per cent green base load power (the minimum amount of electricity needed to keep the lights on) all year round. Based on our calculations, one TPGen24 site alone could power over 1m homes, and when we have good wind and solar, we can use our spare renewable energy to produce green hydrogen. This interplay could help to scale a struggling hydrogen industry in our time of need. Using ‘only’ renewable energy to produce hydrogen through electrolysis on our ‘power islands’ will also limit the high costs of this energy source which have spiked recently due to instability caused by rising energy prices.

Long-term strategies

keep building solar panels and wind turbines, but when the sun isn’t shining and if the wind stops blowing, gas and coal are the only alternative to fill the gaps in supplying muchneeded power to the grid in order to meetWinddemand.andsolar aside, if we were to harness the renewable power using the rise and fall of the tides by building tidal range infrastructure, we could source reliable energy throughout the year, 24/7.
