HELLO 2024!
H
ello and welcome to the first ECN of 2024! I hope you managed to have a restful break and are refreshed and ready for the year to come. Reflecting back on 2023, one of the biggest stories of the year was the increasing adoption of renewable energy sources by electrical contractors. In response to growing concerns about the environmental impact of traditional power sources, along with government targets, many contractors began to invest heavily in solar, wind, and other renewable technologies. This led to a surge in demand for skilled workers in these areas, as well as increased competition among contractors to secure lucrative contracts. Another major development in the industry was the rise of smart homes and buildings. As more and more consumers seek out energy efficient and environmentally friendly solutions for their homes

INDUSTRY NEWS MAJOR CONFERENCE ON ELECTRICAL SAFETY TACKLES FULL LIFECYCLE OF PRODUCTS The clear focus of the 2023 Electrical Product Safety Conference was the importance of the whole product lifecycle. Held at Church House in Westminster, London on 16 November, the day-long event brought together experts and leaders from across government and industry to investigate critical issues, offer solutions, and share insights on the growing need for electrical product innovation to support the UK’s transition to a net zero future. This year’s theme, ‘to market and beyond’, saw experts examine each stage of a product’s life, with sessions focused on safety in design, pre-market, on the market, and end of life decisions. This led to discussions on issues such as how to ensure safety from the outset of product design, the legal responsibilities and due diligence needed to take a product to market, supply chain issues, service and repair, the lack of global regulation, and the pros and cons of product removal versus extended life. Attendees gained insights from renowned experts and industry leaders at the forefront of product safety and learned about the latest legislation and regulations affecting the safety of electrical products. They also saw innovations in electrical safety and how they can help consumers and engaged in discussions and networking with a wide variety of key stakeholders.
DANNY MCBEAN WINS SKILLELECTRIC GOLD Danny McBean has been crowned 2023 SkillELECTRIC champion after excelling in an intensive UK final competition over three days at Oldham College. Taking second place and a silver medal was Ben Gillin from Lloyd Morris Electrical and JTL. Third place and a bronze medal went to Conor McDonnell of Nesbitt Electrical and Southern Regional College in Northern Ireland. Danny, 21, a SECTT apprentice with UHI Moray and employed by Grants (Dufftown), took top marks over his fellow finalists in a complicated electrical installation task comprising four circuits, SWA and FP cable, lights, sockets, conduit, trunking and a smart module. The task had to be completed within a strict timeframe and was marked against tough criteria including wiring and connection skills, inspection and testing and measuring and marking out, which had to be accurate within +/-2mm. In a first for this year, competitors also completed a solar PV-related task. Speaking after his win, Danny said, “I’m absolutely over the moon; I still don’t believe it. When they read out the name I was just frozen for a second! Well done to all the other competitors – all the judges were saying it was really close and one of the most competitive years. I just want to say thank you to my dad who’s my lecturer, for training me and always looking at ways to work harder and more efficiently and to my employer for giving me the time off to practice and take part.” SkillELECTRIC is organised by National Electrotechnical Training (NET), in conjunction with WorldSkills UK. NET, netservices.org.uk
The conference featured the announcement and presentation of Electrical Safety First’s prestigious and coveted Safety Innovation Award, which recognises and rewards innovators, designers and creators delivering forward-thinking approaches to product design and safety. The 2023 winner was HobSensus, designed by Prefect Controls. Electrical Safety First, electricalsafetyfirst.org.uk
30,000 EV CHARGERS TO BE INSTALLED ACROSS THE UK Pozitive Energy and Landis+Gyr have joined forces to deliver the country’s most substantial gear shift in EV charging. The partnership will see a unique delivery model rolled out across the country, with businesses able to access the complete end-to-end EV charging infrastructure, including full installation and management of Landis+Gyr’s premium EV charging solutions, fixed national pricing, ‘tap and go’ payment processes, and the ability to earn revenues or offset energy bills from charge point use. Not only will this make EV charging as accessible and easy as possible for both businesses deploying it and their customers who use it, but it will also help expedite the expansion of the UK’s EV infrastructure, which continues to lag behind other European countries. Nathan Daniels, Head of Electric Vehicles at Pozitive Energy, comments, “Our partnership with Landis+Gyr represents the largest advancement in the UK’s EV market in decades, and will see us together driving forward Britain’s ability to reach its net zero and low carbon targets. “For too long, the country’s EV charging infrastructure has presented a barrier to consumer adoption. Working with Landis+Gyr to develop this unique approach to EV charging will see UK businesses gain access to revenue generating chargepoints, while also offering drivers access to a much more robust and easier to use charging network, thus benefitting us all in an expanding EV infrastructure.” Once deployment has been completed, the partnership will see Pozitive Energy provide the largest network of EV chargers in the UK. Over the next five years, Pozitive Energy expects to install 30,000 of Landis+Gyr’s electric vehicle charging units across the UK. Pozitive Energy, pozitive.energy
SCOTLAND’S LEADING ELECTRICAL BODIES HERALD HEALTHY PIPELINE OF EMERGING YOUNG TALENT Scotland’s electrical bodies are looking ahead to 2024 with confidence as new figures show a healthy pipeline of emerging young talent – but also insist that industry-led apprenticeships are the only way to deliver the future of skills development. The Scottish Joint Industry Board (SJIB), Scottish Electrical Charitable Training Trust (SECTT) and campaigning trade association SELECT have welcomed a report showcasing the youthful age profile of Scottish electricians. They also point to record recruitment levels over the past three years and recent triumphs in national apprentice competitions as further proof of a bright future. They insist that such high standards can only be maintained by industry-approved training. The bodies issued their statement after a new SJIB report found that of the 19,566 people in Scotland with an Electrotechnical Certification Scheme (ECS) card, almost

40% (7,813), are aged between 16 and 29, with just 19% (3,836) aged 50 or over. Some 4,603 (24%) holders of the accreditation permitting them to carry out electrical work are aged between 30-39, with 17% (3,314) in the 40-49 bracket. Fiona Harper, Secretary of the SJIB, says “These encouraging findings counter the oft-heard fears of an ageing workforce that won’t be replaced. Instead, it suggests an engaged and eager younger generation who are already embracing the challenge of new technology and will continue to safely heat and power our homes and businesses for generations to come.” However, Fiona warned that there is no substitute for a proper apprenticeship and that the bodies would continue to rigorously promote employer-led training.

INDUSTRY NEWS MCS SURPASSES 4,000 CERTIFIED CONTRACTORS MCS (the Microgeneration Certification Scheme) has surpassed 4,000 MCS-certified contractors. The growth in the number of certified companies installing low carbon technology highlights the growth in consumer confidence in home-grown energy across the UK and reflects the growing demand for MCS-certified contractors across the nation. In October, MCS certified its 4,000th contractor, as the number of homeowners looking for certified installers to retrofit their homes with solar panels, heat pumps and other renewable technologies continued to grow. MCS certification is a mark of quality, providing assurance to consumers. Being MCS certified demonstrates that a contractor installs renewable energy and heating systems to industry-expected levels of quality every time. 2023 was a record-breaking year for MCS so far as the scheme saw over 1,700 new contractors becoming certified, a 70% growth in the contractor base since the end of 2022. In fact, more contractors joined the scheme in 2023 than in the previous six years of the scheme combined. At the end of 2022, MCS had fewer than 2,000 solar PV contractors – now it has over 3,200. This growth mirrors the rapid rise in certified solar PV installations across the UK and the growing demand amongst homeowners to generate their own home-grown electricity, reducing energy bills, claiming energy independence, and decreasing their carbon footprint. The scheme has also recorded over 200,000 certified installations of small-scale technologies in 2023. It’s been a notable year for heat pumps, with over 34,000 certified heat pump installations – more than any other year end figure in the scheme’s history. MCS, mcscertified.com
INTERNATIONAL LIGHTING BRAND LAUNCHES IN THE UK Performance iN Lighting (part of the Gewiss Group), a lighting manufacturer across Europe and the USA, has formally launched into the UK market. Performance iN Lighting’s headquarters are in Verona, Italy, with operations across more than 100 countries worldwide. Paul Dawson, Managing Director of Gewiss UK, says, “We’re hugely excited to be bringing Performance iN Lighting’s range of indoor and outdoor lighting products to the UK for the very first time.

ECA UNVEILS NEW CHARTER TO RECHARGE ELECTRICAL SKILLS The Electrical Contractors Association (ECA) has unveiled a new charter to recharge electrical skills at a reception in the House of Commons. The charter, supported by ECA Member businesses, parliamentarians and other stakeholders, aims to secure the growth of the skilled electrical workforce, which is significant in reaching the UK’s net zero goals. ECA maintains the belief that to create more ‘green jobs’ in the future, it is a requirement to have an appropriately trained and thriving electrical workforce. It should commence with a solid foundation of trade competence, achieved through a multi-year electrical apprenticeship, and supplemented by specialised upskilling training in specific net zero technologies. To accomplish this in England, ECA believes three main changes are necessary: • Policymakers engaging directly with the electrical sector • A 30% uplift in English electrical apprenticeship places, in addition to the 40% growth already achieved • Restoring the severely broken skills pipeline connecting college-based education and employment in the industry In a reception at Westminster on 27 November, leading parliamentarians and various ECA Members called for the government to collaborate with the sector and reconsider the recruitment process by preparing electricians for the opportunities and challenges associated with a net zero world. Speaking at the event in Parliament, Andrew Eldred, Director of Workforce and Public Affairs said, “Competent, qualified electricians are indispensable for a safe and reliable transition to net zero. We already have a strong national skills base, and the growth in the workforce that is required is entirely achievable – but we need public policy to support and assist industry in achieving this goal, rather than obstructing or undermining it.” ECA, eca.co.uk
BAXI EXPLORES IMPROVED OPPORTUNITIES FOR WOMEN IN CONSTRUCTION Following the launch of the Construction Inclusion Coalition in September, Founder Member, Baxi, hosted a roundtable discussion at RIBA, The Royal Institute of British Architects, focused on addressing gender imbalance and other equality, diversity and inclusion (EDI) considerations in the construction industry. The roundtable was hosted by Karen Boswell OBE, who was joined by 10 experienced leaders from around the sector. The discussion aimed to answer the question: how can the sector and supply chain improve its attractiveness to women, and what can be done to improve retention rates and reduce women leavers? Recent CIC research found that only 15% of construction sector workers are women, and just 6% are from ethnic minority backgrounds. Yet a CIC poll of
over 2,000 UK adults in July 2023 found that 46% of people said they would be more likely to look for roles in construction if the sector demonstrated a strong commitment to diversity and inclusion. The group identified a number of barriers preventing women from entering the industry and considered ways to overcome them, including greater collaboration, gender neutral communication, increased relevance, better job design and a stronger expression of the social value created by the sector in order to attract people with a desire to participate with a sense of purpose. The discussion landed on three areas where companies across the sector could quickly start to make changes to improve their attractiveness to women: allyship, communication and collaboration.

Speaking after the event, Karen said, “We must ensure that everyone feels comfortable in their role, regardless of gender and background – there is a growing body of evidence that clearly points to the improved commercial and reputational performance of companies who embrace diversity and use it to innovate, engage and collaborate to delight customers.” Baxi, baxi.co.uk

The Selectric GRID360 Kinetic wall switches have been proven to be reliable in quality, stable in signal transmission, and well-designed in appearance, which will fit into the company’s ever-popular GRID360 range of products. Furthermore, the Selectric GRID360 Kinetic system uses a very small amount of energy and therefore reduces overall power consumption, which will result in economic savings and contribute towards an improved carbon footprint. There is a wide range of receivers to choose from to solve real-life controlling requirements and Selectric offers a range of non-dimmable, dimmable and smart receivers suitable for wide input voltage from AC85-240V 50/60Hz. The lowest and highest brightness levels can be set by an app on the smart dimmer. This helps the performance and compatibility of the dimmer to suit more dimmable light fittings whilst avoiding flicker and slow response issues often found with smart dimmers. A 30m transmission range (depending on context) ensures the switches will perform steadily under complex indoor installations (70m for outdoor).

CONTRACT NEWS LAMBETH PIER CONNECTION PAVES WAY FOR GREENER RIVER THAMES Electric boats along the River Thames will soon be able to plug in to charge and reduce emissions, thanks to a partnership between UK Power Networks and Net Zero Marine Services (NZMS). UK Power Networks, which distributes energy across London, the East and the South East of the UK, will deliver 1.5MVA of energy to NZMS’s new battery storage facility, which will be used to charge electric boats on the River Thames. This will be the UK’s first ever high voltage shore power station above tidal waters. The substation will be based on a fixed tidal platform above an ebb and flow tidal range of 7m. As part of the works, UK Power Networks installed 1.8km of new cables and equipment, allowing the electrification of boats along the Thames. This means lower carbon emissions, reduced water contamination and cleaner air for London. UK Power Networks has invested £1.2m into the local electricity network, enabling the connection to be made. The connection, near Lambeth riverside, was made in June 2023 – a month ahead of schedule and will be used from next summer. UK Power Networks, ukpowernetworks.co.uk
ENHANCED CROSS-VENUE COMMUNICATION AND COLLABORATION FOR SHAKESPEARE’S GLOBE Riedel Communications has announced that Shakespeare’s Globe, the world-renowned performing arts venue in London, has implemented the company’s Bolero intercom system to drive communications for its two theatres, the Globe and the Sam Wanamaker Playhouse. The Bolero addresses the main challenges of communication within and across these live theatre environments. It addresses these problems by adding a new level of efficiency, clarity and collaboration for stage management, rehearsals and show running. By adopting the Bolero system, Shakespeare’s Globe has streamlined its workflows, resulting in increased efficiency and resource optimisation. With the dramatic improvement in the range and clarity of communication across both venues, the performing arts venue simultaneously reduced the required number of antennas from nine to three. The limited need for troubleshooting has eliminated downtime and waiting periods, ensuring technical rehearsals proceed seamlessly. In addition, the Bolero system yielded financial savings, eliminating the need for a standby technician during technical rehearsals and thereby efficiently reallocating resources overall. Moreover, the Bolero system has enabled Shakespeare’s Globe to rely on communication cues for complex sequences, adding an extra layer of failsafe to its performances.

CONTRACT NEWS LUCECO LIGHTS UP LUTTRELLSTOWN CASTLE Luttrellstown Castle Resort near Dublin is a luxurious venue for elegant hospitality and entertainment, combining the original 15th Century castle, 567 acres of parkland, and a championship golf course with an alpine lodge-style clubhouse. It also hosts weddings, garden parties, business meetings and conferences. The site has multiple needs in terms of lighting and the plan to renew and upgrade the lighting had to cover a range of considerations. Luceco Group was chosen for the task. With the castle being the jewel in the crown of the Luttrellstown estate, daytime and night-time photos of the castle were studied to get a more comprehensive understanding of the impact of different lighting configurations and settings. Once the specifications had been approved, Crystal Engineering, an installation partner working closely with Luceco, was then engaged to order and fulfil the installation. Luceco replaced all the interior lighting with LEDs. It also specified High Bay lighting for the castle’s lamps and chandeliers, in addition to the British General Evolve range of sockets and switches in matte black, modernising the look, whilst retaining the original opulence.
The Evolve range was also used in Luttrellstown’s restaurant, adding a subtle elegance to the room. Exterior lighting was also upgraded to further improve aesthetics, with Kingfisher
Bollards installed in the driveway and around the golf course. More LED efficient panel lighting and emergency lighting were added around the golf course, while solar Guardian floodlights were installed on roofs.
Finally, Luceco’s Elara Bay fittings were installed in the greenkeeper’s shed. Ahead of a large event, this facility is sometimes used at night, so, the critical issue is maximising safety. Luceco, luceco.com

KEY ISSUE
2024 — THE YEAR OF THE BATTERY Chris Cowling, Aztec Solar Energy’s Commercial Director, reflects on a mixed, yet fast-moving year for the solar photovoltaic (PV) and battery storage market and looks ahead to even brighter times in 2024.
W
hen reflecting on the past 12 months, there would be few who would not struggle to use the word ‘challenging’ to describe 2023. It feels somewhat overused, however, coming through a disruptive global pandemic, with an economy impacted by significant conflict in Europe and latterly the Middle East, it has, without question, been just that. Yet, 2023 also saw pockets of real buoyancy, not least in the UK solar energy market. Underpinned by a strong desire for business owners to protect livelihoods by adopting cost-effective and self-managed approaches to energy and sustainability, while protecting a planet for future generations. So, it’s fair to say, 2023 has been a real mixed bag, often presenting a dichotomy of business decisions.
PV – an investment opportunity
Aztec Solar Energy has been fortunate, as the UK solar energy market has seen substantial growth. 2023’s estimate is that it will have reached over 15GW of installed capacity and the upward curve continues, expecting to hit 43GW within the next five years. Globally, despite lingering supply chain and trade issues, a similar picture is replicated with continued significant growth predicted. As a share of global energy generation, in 2021 global PV was 3.6% and rose to 4.5% in 2022. It has become the most rapidly growing regeneration technology and one of the best energy investment opportunities.
Volatility
Alongside the ups are inevitably some downs. The complex and ever-shifting economic backdrop continues to create volatility and is taking its toll in the general construction market. Further impacted by predictions that commercial new builds are slowing down, Aztec Solar Energy is seeing debt risk and borrowing rising; yet the company’s access to a wide range of funding options means it can support customers through this. Aztec Solar Energy also faced increases in materials costs in early 2023, although it doesn’t anticipate these continuing and is optimistic that levels will remain constant.

2023 saw pockets of real buoyancy, not least in the UK solar energy market
Increased efficiencies
In a relatively new and evolving market, exciting new technological developments often present good news. As we saw in 2023 with the launch of new N-type panels from several different manufacturers, delivering greater efficiencies, more power, improved robustness and safety features, and reduced degradation. These improvements add even greater confidence in the solar marketplace.
Safety
Safety remains high on Aztec Solar Energy’s agenda and as such the company has become an avid supporter of the new Solar Stewardship Scheme proposed by trade association, Solar Energy UK. Encouraging the early adoption in 2024 of a Joint Code of Practice for solar PV specifiers, designers, suppliers, operators, and insurers; the RC62 is designed to further improve safety for commercial and industrial rooftop-mounted PV installations. In addition to industry-wide standards, it will include a guide for insurers and clients on procurement, ownership, and operation and maintenance. Aztec Solar Energy says it is keen to see this initiative move forward as soon as possible.
The year of the battery
Predictions for 2024 are that the commercial solar rooftop market is set to take off. With decarbonisation high on the agenda and increased recognition of the benefits of self-generated energy and more affordable

@ElecConNews
storage options, 2024 will see a substantial growth in battery storage installations. Batteries allow businesses to store power and draw on it when needed, as well as being force charged overnight at lower electricity rates and the energy used in the day when electricity rates are higher. Battery size and costs have decreased over the past five years by at least 40%. So, the next 12 months will be bright. As the PV solar market expands year on year, it will be about how all involved are seizing that opportunity. Inevitably, like many other sectors, this sector will be facing resourcing issues and it needs to encourage the development of skilled electrical installers to meet the growing demands. At Aztec Solar Energy, the company’s expansion year on year will see further developments, with a branding refresh in order that it is best positioned to capitalise on the growth opportunity. Also having recently become the UK’s specialist commercial PV and battery systems partner for the Effective Energy Group, this will accelerate the company’s expansion plans. As both the commercial and private sector landscapes change around us, we will see more PV and battery systems, powering an increasing number of local and national services, creating improved energy security and capitalising on the power of greener energy solutions for all. We should embrace 2024 with optimism and commitment to a brighter and greener future. Aztec Solar Energy, aztecsolarenergy.co.uk

PROJECT FOCUS
HOW SURE IS PLOTTING A PATH TOWARDS NET ZERO Centiel has replaced monolithic UPS systems with its three phase modular UPS CumulusPower at Sure’s Gurnsey data centre facility.
S
ure’s Tier III data centres on the Channel Islands keep some of Europe’s largest organisations’ critical data safe and secure in a location outside of mainland UK and Europe. Sure also offers a range of services that goes beyond traditional telecoms to connect the island homes. As an organisation, Sure requires the highest level of uptime and is also committed to reducing energy usage throughout its facilities. Legacy monolithic uninterruptable power supplies (UPS) offered only 80% efficiency, which Sure saw as no longer acceptable from an energy waste point of view, especially now that the company is on a zero carbon path. In addition, some of the UPS’ were 13 years old and, as such, Sure expected to see issues with controllers, capacitors and fans. UPS manufacturer, Centiel, has worked with Sure since 2018. However, the past year saw the completion of work to replace monolithic UPS systems with Centiel’s three phase modular UPS CumulusPower in data centres 4,5 and 8 at Sure’s Gurnsey facility. Centiel’s three phase, true modular UPS CumulusPower provides ‘nine nines’ (99.9999999%) availability to effectively eliminate system downtime; class leading 97.1% online efficiency to minimise running costs; and true ‘hot swap’ modules to eliminate human error in operation. CumulusPower now takes Sure’s energy efficiency to another level, saving significant costs and reducing carbon footprint. Due to the true modular nature
of CumulusPower, it is highly efficient, meaning it runs at 97% efficiency compared with <80% for the previous UPS. Centiel now helps to provide the highest level of resilience and availability (up time) with a total of 1.58MW power backup across Sure’s Channel Island facilities. Simon Roger, Facilities Manager, Sure, explains, “The alternative to this project was to replace like for like, which would not pay back at all and would maintain the current costs and losses due to inefficiencies. We could have done nothing, which would increase the risk of system failure until eventual end-of-life, which could result in a total loss of power to the customers and Sure infrastructure loads which was unacceptable. Instead, we chose Centiel’s CumulusPower as the leading power protection technology on the market which would help us take a significant step to reducing energy consumption on our path to net zero.” Successful installation, full testing and commissioning meant the entire UPS changeover was completed within a week and with zero downtime.
Enabling in-house first response
On the Channel Islands, a fast response time for essential UPS maintenance presents challenges as it requires a manufacturer trained engineer to fly to the Islands to complete necessary work. Uniquely, CumulusPower’s modules can be ‘hot/safe swapped’ in a running load, therefore Centiel’s training of Sure engineers means Sure now has its own in-house first level response. Sure’s team can now complete basic monitoring, diagnostics and maintenance of the UPS. On the rare occasion a fault does occur, modules can be simply swapped in less than three minutes, and then the faulty module shipped for testing and repair at Centiel.
Increased availability
Centiel says that its distributed and decentralised architecture also adds far more layers of resilience than other UPS architectures. The highest level of availability is achieved because all of the components are replicated throughout the system and at module level where each UPS module includes rectifier, inverter, static bypass, and control logic. No single module takes control of the decisions for the whole system, instead, distributed decision making takes place to eliminate the logic’s single point of failure. This automated process ensures that the critical load is always protected.

Centiel’s CumulusPower takes Sure’s energy efficiency to another level, saving significant costs and reducing carbon footprint
Further, the safe-hot-swap modular design plus training means modules can easily be replaced or moved to areas of high demand, offering increased flexibility. This also means each area of the facility is constantly right sized in terms of UPS power back-up, which can also save money and energy.
Results
Simon confirms, “CumulusPower is highly efficient, meaning it runs at 97% efficiency compared with 80% for our previous UPS. I am pleased to say that the UPS replacements in DC’s 4 and 5 are now complete with no more switching events required and the change requests are both closed. We have seen the predicted instant power savings to support the ~£30K per annum in DC 5 and ~£70K in DC 4 at today’s rates, equating to savings of an estimated 20-30% with the current IT load. The UPS are also uber reliable and take up less space, and we have saved around seven racks on this installation, which can be used for clients. “CumulusPower is also unique in the market because it enables UPS modules to be swapped safely by our trained team without switching the UPS off. This hot-swap functionality means even if we need to replace a module and send it for repair, we do not experience any downtime, ensuring maximum availability for our clients.” Centiel, centiel.co.uk

TIS IS REALLY EXCITED TO HAVE WON THE TOOLS/TESTING PRODUCT OF THE YEAR 2023 WITH OUR TIS 570 AC & DC LEAKAGE CLAMPMETER The product won the category due to it not only being a massive time saver for board changes & finding AC leakage problems causing nuisance RCD tripping, but a not to be under estimated potential life-saving feature in that the tester is able to distinguish & measure DC leakage on electrical systems, even if it is super-imposed on AC currents.
WHY IS BEING ABLE TO DETECT DC LEAKAGE SO IMPORTANT? DC leakage is now increasingly prevalent due to Electric Vehicle batteries, Solar PV & battery storage systems. If more than 6mA of DC leakage flows in a circuit, then all AC, A & F type RCDs can be ‘blinded’ & therefore may not trip in a fault condition. The installation of ‘B’ type RCDs or ‘RDC DDs’ will pick up pure DC leakage current & trip if there is more than 6mA of DC leakage. The bigger picture with detecting DC leakage is also that it can propagate to different properties, meaning a house without any DC current generating equipment could be effected by a neighbour who has - therefore the detection of DC leakage is vitally important. The TIS 570 is the only combined AC & DC leakage clampmeter currently readily available on the UK market. DC leakage, if left unchecked can also cause corrosion within the fabric of metal &/or metal reinforced buildings.

ENERGY EFFICIENCY METERING RECOMMENDATIONS Jake Green, Head of Technical Engagement with Scolmore Group, considers three documents relevant to the electrical industry and their requirement for suitable metering: one legislative, one a British Standard relevant to the electrical industry, and one a specific guidance document for a particular industry.
T
he UK government has committed the UK to net zero greenhouse gas emissions by 2050. This commitment is set out in the Climate Change Act 2008 (2050 Target Amendment) Order 2019. Furthermore, the government has committed to cutting greenhouse gas emissions by at least 68% by 2030 when compared to 1990 levels. To achieve these targets, legislation, British Standards and other guidance covering energy efficiency and energy management drive various industries to effect change in the way they monitor, use and manage energy. In this article, Jake considers three documents relevant to the electrical industry and their requirement for suitable metering: Building Regulations 2010 • • BS HD 60364-8-1: 2019 Low-voltage electrical installations Part 8-1: Functional aspects – Energy efficiency TM50: 2021 – Energy efficiency in • commercial kitchens.
Building Regulations 2010
building services which are energy efficient to a reasonable standard, have effective controls, and are commissioned by testing and adjusting as necessary to ensure they use no more fuel than is reasonable in the circumstances’. The recommendations detailed in Part L are separated into those relevant for domestic premises and those for non-domestic premises. Within non-domestic premises, clause 5.17 of Approved Document L2 (ADL2) recommends that ‘energy sub-metering

is installed in new buildings or when fixed building services are provided or extended in an existing building, and should meet the following…’: • End user categories (heating, lighting, cooling etc.) are sub-metered in such a way that at least 90% of the annual energy consumption of each fuel can be suitably assigned (refer to CIBSE TM39) Metering enables the comparison of • forecast energy use and in-performance energy and facilitates energy reporting • Metering allows the energy use of different tenants to be separately monitored The outputs of renewable systems are • separately monitored Buildings with a floor area exceeding • 1000m2 have automatic meter reading and data collection facilities
B S HD 60364-8-1: 2019 Low-voltage electrical installations Part 8-1: Functional aspects – Energy efficiency BS HD 60364-8-1: 2019 Low-voltage electrical installations Part 8-1: Functional aspects – Energy efficiency ‘…provides additional requirements, measures and recommendations for the design, erection, operation and verification…for optimising the overall efficient use of electricity.’ Whilst it has not been possible to incorporate this standard into BS 7671, BSI has published BS HD 60364-8-1 as a separate harmonised document (HD). It can be used when, for example, a specification references requirements for electrical energy management and efficiency. Clause 7.6 of BS HD 60364-8-1 requires that energy efficiency is considered at every stage and that the installation of fixed equipment for power metering and monitoring, amongst other things, is considered for new constructions and future modifications.
SPECIAL FEATURE
Clause 8.3.1.3 requires that measurement equipment is installed according to the application and its location within the installation. The types of power metering and monitoring devices (PMD) will depend upon the required function(s). The following applies: • PMD-I: Energy efficiency: energy usage analysis for energy efficiency assessment • PMD-II: Basic power monitoring: power monitoring for electrical energy distribution monitoring and control within the installation • PMD-III: Advanced power monitoring and network performance: advanced power monitoring and network performance monitoring (BS EN IEC 61557-12: 2022+A1 refers) As with Approved Document L2, the requirement to sub-meter the installation is key to ensuring that energy usage over time is taken into account.
TM50: 2021 – Energy efficiency in commercial kitchens By way of an industry specific example, the CIBSE guide TM50: 2021 states, ‘This document offers guidance on how to make ‘positive’ design choices that would support a more sustainable outcome.’ New commercial kitchens will, or should, benefit from a more modern approach to energy efficiency processes and practices as part of the design and build. This will include suitable sub-metering and monitoring of energy usage. Such monitoring allows for the review of energy usage across key areas, such as lighting, heating and kitchen equipment. For existing kitchens, it becomes even more important that sub-metering and monitoring is installed, to allow for each area to be considered separately from the total energy usage measured by the incoming meter. The guide details the key benefits of sub-metering:
NEW ELUCIAN 100A SINGLE PHASE ENERGY METER FROM CLICK Scolmore continues to expand its Elucian consumer unit range to provide contractors with the broadest possible range of units and protective devices to cater for all installation requirements. The latest addition to Elucian is the new 100A Single Phase Energy Meter.

with the power distribution. This is all down to the reliable, high-quality products and solutions ABB provides.” The upgrades included a turnkey MV circuit breaker retrofit, where SF6-insulated models have been replaced with next generation VD4 vacuum circuit breakers. These new devices clear potentially harmful short-circuit faults in tens of milliseconds, thereby preventing severe damage to the hospital’s electrical infrastructure and minimising the risk of downtime. What’s more, thanks to ABB’s full-circle end of life service, the old SF6 breakers and gases were disposed of safely and sustainably, eliminating the risk of severe

environmental impact and adhering to strict national laws. The ageing relays in the switchgear were also replaced with ABB’s Relion protection relays from the 615 series, REF615. These protection relays offer extensive protection and control functionality to ensure uninterrupted power supply. In this project, a solution was implemented where reliable and fast arc fault protection is now ensured with ABB’s REA 101 modules. The protection is based on optical arc flash detection with fibre-optic light sensors, tripping at arc faults in milliseconds. Sixten Holm, Business Development Manager at ABB in Finland, says, “For service providers such as HUS, one of the greatest opportunities for improving reliability and reducing carbon and costs is by modernising outdated components, rather than replacing the entire switchgear. Replacing ageing circuit breakers and protection relays can also be done quickly with minimal downtime.” This timely and essential overhaul has given HUS a technologically driven and environmentally friendly solution that improves reliability, security and safety. But to reduce operating costs in the long term, it needed to be supplemented by an intelligent system that could optimise the hospital group’s maintenance activities. ABB Ability Energy and Asset Manager was installed to facilitate remote monitoring and provide HUS personnel with real-time information on the condition of equipment, such as temperatures, with alarms from devices alerting them instantly by text message. This level of predictive maintenance
ensures early warnings of any potential failures, providing crucial information to act upon to avoid unplanned downtime. In addition, specific condition monitoring for the MV switchgear is now available, which allows HUS to carry out maintenance when necessary, according to the actual condition of the devices. ABB’s SWICOM diagnostics system reports the mechanical and electrical health status of the equipment in real-time. One SWICOM unit is enough to cover the data of the entire switchgear system. The data can be viewed – anytime, anywhere and even remotely. At HUS, SWICOM will soon be extended, allowing other equipment to also benefit. As part of the project, the low voltage circuit breakers were also upgraded to enable connectivity to the ABB Abilit cloud service for first-hand condition monitoring. Sixten concludes, “It has never been more important to both optimise maintenance and operational costs and manage future demands, thus introducing SWICOM was a great way forward for HUS. It has enabled them to pre-empt unexpected outages, increase flexibility, boost efficiencies and maintain a digitalised electrical infrastructure that is fit for purpose.” On working with ABB, Jari-Pekka adds, “With a long-standing partnership, where you know and trust the people, it’s easy to discuss if there are issues and achieve a good outcome. I would recommend ABB’s solutions to others, as the collaboration with ABB on our power distribution wants and needs has been excellent.” ABB, global.abb

HEAT PUMP INSTALLATION — 18TH EDITION RCDS? Irrespective of your views on the UK government’s recent announcement relating to ‘The Clean Heat Market Mechanism’ launch in 2024, it’s another tool in the box, supporting a tenfold increase in heat pump installations by 2028 when compared to 2022. Whatever the final figures, heat pumps still represent a major growth opportunity for UK installers in this decade, writes Chaz Andrews, Technical Manager, Doepke UK.
I
nverter based control is central to the operation of heat pump systems and fundamental to the UK, as most domestic properties are connected to single-phase supplies. In installations requiring RCD protection, the characteristics of the inbuilt inverter equipment determine the Type of RCD to be installed upstream.
Equipment design characteristics
For single-phase installations, the use of Type F or B RCDs is governed by the level of smooth DC residual current produced under certain fault conditions. This fault current is related to the value of the ‘DC link voltage (Figure 1) i.e. it is a function of the internal equipment design. Three-phase inverter-based equipment without built-in galvanic isolation requires the use of type B RCDs – see BS 7671 531.3.3. (iv). For additional information refer to Techpub-17 on the Doepke website .
DC link voltage dictates the Type of RCD
Figure 1 gives a generic example of a single-phase combined compressor and fan unit. The DC voltage output from the rectifier will be a minimum of 1.41 x AC RMS voltage. Designs may include a step-up voltage section to increase the DC voltage before it is fed into PWM control section. Capacitors connected across the DC bus
provide smoothing for the non-conducting period associated with the AC supply. For example, a high resistance fault between the DC link section and the HP’s earthed casing (IF = VL/RF), results in a low value smooth DC residual current flowing in the PE conductor. RCDs connected in series with the HP will be subject to a function (<IF) of this smooth DC residual current. If the heat pump manufacturer cannot provide advice on the Type of RCD that should be used with its equipment, the only safe option is Type B – see BS7671 531.3.3: • Smooth DC fault current <10 mA: Type F RCD can be used – see (iii) Note 2. • Smooth DC fault current >10 mA: Type B RCD must be used – see (iv) Note 3. Note, you cannot install Type F or B RCDs downstream of Type A RCDs.
HP and RCD sensitivity
To reduce the risk of unwanted tripping, BS7671 531.3.2 (ii) recommends that the AC operational leakage (PE) current is ≤30% of the RCD sensitivity (I∆n). The reasoning behind this is that the RCD may trip at >0.5 I∆n. PE current can increase because of supply quality (harmonics) e.g. filters, inverters, LED lighting and the amount of local PV generation. When adding new equipment to an existing installation containing an RCD incomer, consider the addition of PE currents, i.e. existing equipment and new equipment. Type F and Type B RCDs are designed to respond to the sum of the leakage/residual current, generated at various frequencies
Improved heat pump designs with reduced starting current peaks and increased efficiency
by inverter-controlled equipment – see Techpub-17. Before purchasing equipment, check the installation manuals to verify the minimum RCD sensitivity requirements. If it is not in the manual, ask the supplier to provide this information before you purchase. BS7671 543.7.1 places limits on the PE current, based on the method of connection: • <10 mA: Plug connection and 30mA RCD or permanently wired to the supply. • >10 mA: Additional requirements apply to the PE conductor – see 543.7.1.202 & 3.
Conclusion
Check the heat pump manufacturer’s installation requirements, relating to the use of specific RCDs. Ask the manufacturer for advice before installing equipment. To reduce the risk of unwanted tripping, the AC leakage (PE conductor current) must be compatible with the installation design and associated RCD sensitivity – ref 531.3.2. Type F or B RCDs must not be installed downstream of Type A RCDs (in series). Assumptions can be costly, so check before purchasing equipment.

Here Glenn provides insights into how the emergency lighting industry is evolving to be more environmentally friendly, telling us more about the technology beyond compliance: “The landscape of the emergency lighting industry is experiencing a transformative evolution, driven not only by regulatory mandates, but also by a genuine commitment to environmental sustainability. At the forefront of this change is the integration of advanced technologies that go beyond mere compliance, fundamentally reshaping how emergency lighting systems operate. “One significant technological leap involves the widespread adoption of LED lighting. LEDs offer a compelling trifecta of benefits: energy efficiency, an extended lifespan, and a substantially reduced carbon footprint. As emergency lighting systems traditionally need to be operational for extended periods, the energy efficiency of LEDs not only reduces operational costs but also aligns with global efforts to minimise energy consumption and combat climate change. “Beyond the realm of illumination, the emergency lighting sector is embracing smart systems with open arms. These intelligent solutions leverage data and connectivity to enhance overall system performance. Predictive maintenance, for example, is a game-changer, allowing for proactive identification and resolution of potential issues before they compromise system reliability. This not only improves the overall functionality of emergency lighting, but also contributes to energy optimisation – a critical factor in sustainable practices. “Furthermore, the industry is exploring the integration of renewable energy sources into emergency lighting systems. Solar and wind power, in particular, are being harnessed to reduce dependency on traditional energy grids, enhancing the resilience of emergency lighting solutions in diverse environments. Paired with energy storage solutions, these systems can maintain functionality even during power outages, contributing to a more reliable and sustainable emergency preparedness infrastructure. “The commitment to environmental responsibility goes hand in hand with a broader societal shift towards eco-friendly practices. Emergency lighting manufacturers are increasingly considering the entire lifecycle of their products, from production to disposal, to minimise environmental impact. This includes using recyclable materials, implementing eco-friendly manufacturing processes, and designing products with end-of-life considerations. “The future of emergency lighting is evolving further towards environmental friendliness and is going beyond meeting regulatory standards. Through the integration of advanced LED technologies, smart systems, and a commitment to renewable energy sources, the industry is not only enhancing operational efficiency but also actively contributing to global sustainability goals.

EMERGENCY LIGHTING
GROWTH IN LITHIUM BATTERIES IN EMERGENCY LIGHTING Richard Raeburn, Emergency Specialist at Tridonic, explores the reasons why the demand for Lithium Iron Phosphate battery technology is growing, as well as the future developments that will impact the emergency lighting industry.
W
hile nickel metal hydride and nickel cadmium batteries are still incredibly popular in emergency lighting, there is a definite shift towards Lithium Iron Phosphate (LiFePO4) technology. When compared to the legacy technologies, this newer solution offers several benefits. Firstly, this newer technology does not contain cadmium – a toxic heavy metal that is classified as hazardous waste. LiFePo4 contains no heavy metals, so it doesn’t have the same toxicity, making it safer to handle and easier to deal with once it comes to the end of its life. With the fact that LiFeP04 batteries can be recycled to recover the materials used in their electrodes, wiring, and casings, they are considered to have the lowest impact on the environment. In addition, LiFePO4 batteries offer a lower self-discharge rate. This means they operate with periodic top-ups, rather than the constant charge that a nickel battery needs to be able to function. This reduces the power required for charging, which lowers overall power consumption. LiFePO4 batteries are hardy and robust, making them suitable for a variety of LED applications. Application flexibility is improved due to the smaller size of LiFePo4 batteries, but a higher energy content than its nickel counterparts. While these benefits cannot be disputed, it is important to be aware that care does still need to be taken when using Lithium batteries. Where application temperatures are high or low, LiFePO4 batteries still need to be managed, while charging needs to be monitored to ensure maximum lifetime. This was the driver for the development of the LiFeGuard battery monitoring system, a protective mechanism that was included in Tridonic’s Lithium Iron Phosphate emergency battery products since their inception. LiFeGuard is a three-layer system of protection. Firstly, a pressure vent allows gases to be expelled from within the cell. Secondly, an integrated temperature sensor allows for the monitoring of over-charge, over-discharge and short circuiting. Finally, the system monitors the battery and switches off charging should temperatures exceed critical limits. Charging is resumed once the cell temperature is within specified limits. This layered protection approach ensures the battery is used within its operating
46 | January 2024
Emergency Lighting (Tridonic).indd 46
capabilities, which increases its lifespan and operating abilities. Tridonic’s R2A solution shows there is a better way to operate emergency lighting. This award-winning LED emergency module which utilises the LiFeGuard monitoring system has been on the market for more than four years with no known battery failure, demonstrating the capabilities of this technology including longevity, robustness and efficiency of the battery. The statutory requirements covering emergency lighting are changing. Two standards are due to be updated and will most likely be in force by early 2023. The two standards – IEC 61347-2-7 and IEC 60598-2-22 – will govern that Lithium Iron systems must have some form of inherent protection device to ensure the battery life can be maximised. While these updated standards won’t guarantee that Lithium Iron batteries become the norm in installations, there is hope that they will raise awareness of the benefits of this more modern technology. It has been very common for nickel-based batteries to simply be replaced with the same technology for ease, but expectations and requirements are evolving. The benefits of Lithium Iron’s reliability cannot be overlooked, and this stands to be strengthened through the guaranteed inclusion of battery protection. When the technology’s higher green credentials are also understood, this will make the use of a Lithium Iron battery much more appealing. Even with all of the advantages being very clear, there is still some scepticism in the market around LiFePO4 technology. This is somewhat surprising, given its usage in everyday devices such as mobile phones, laptops and power tools. Compounding this, a counter to using LiFePO4 will always be cost. Given nickel-based batteries’ prevalence in the market, they are considerably cheaper at initial purchase. However, savings can undoubtedly be made through lower energy consumption, better longevity, and reduced maintenance costs – which can all be realised by switching to Lithium Iron alternatives. The other significant benefit of Lithium Iron batteries with integral monitoring is that, given the technology’s much lower rate of failure, staying compliant with emergency lighting legislation will become much easier. This will be even truer when the standards are introduced, making monitoring of this battery type a mandatory requirement.

It is not just the move to Lithium Iron Phosphate batteries that is ahead for the emergency lighting sector. Tridonic emergency inverters also incorporate automatic monitoring and storage of critical operating parameters. This information can be read out from the device and can be used in the analysis of the emergency luminaire or detect possible problems in the installation. This feature is called ‘BlackBox’ and Tridonic hopes that access to this data will soon be possible in the application rather than just through base analysis. This would assist the end-user or maintenance team to quickly establish any external root cause of a failure such as excess emergency operations, mains voltage or temperature events. Use of this and other recorded data allied to a DALI automated monitoring system may enable insights as to the most efficient operation of the emergency lighting, to maximise compliance and reduce maintenance costs. Tridonic says that it welcomes the new standards, recognising the opportunities it will present for the industry to move away from the toxic nature of traditional battery technologies. Aligning this legislative change with awareness-raising across the industry has the potential to help us move towards a greener, safer future in emergency lighting applications.

EMERGENCY LIGHTING
THE IMPORTANCE OF MAINTAINING EMERGENCY LIGHTING SYSTEMS With accountability and the Golden Thread high on the building safety agenda, NVC Lighting’s Technical Manager, Peter Adams, stresses how crucial it is that electrical contractors emphasise the importance of emergency lighting maintenance and testing to building and facilities managers.
F
or electrical contractors, emergency lighting is all about the right products being installed in the right places to ensure the system is fit for purpose. An emergency lighting system’s role in the context of a building is primarily functional – what’s paramount is that it does exactly what it’s installed to do when necessary. The two standards which form part of the BS 5266-1 Emergency Lighting guidance, namely EN 1838 and EN 50172, are currently being updated and expected to be ratified next year. Whilst the final details of these updates are still being finalised, it is clear they will bring attention to the importance of ensuring an emergency lighting system is still fit for purpose in a commercial building and the simple steps that electrical contractors can take to ensure this. As a crucial part of a safety critical system designed to safeguard individuals inside a building during emergencies, responsible persons must ensure emergency lighting is regularly maintained and tested. It is a legal requirement to ensure that emergency lighting comes on in an emergency, at a brightness that allows people to exit the building safely. Testing and maintenance in the form of monthly ‘flick tests’ and an annual duration test are crucial to achieving this. However, it’s not merely about conducting tests – the recording, tracking and understanding of their results is also important. A flick test uses a momentary power interruption to show that the lighting works under a loss of power condition. A record of all monthly tests must be kept, including any faults which will have to be reported. Duration tests are an annual requirement lasting three hours, where the primary light circuit must be switched off and the emergency lights left on for the full duration, with any defects to be reported and resolved as soon as possible. Luckily, product manufacturers have strived to make testing as easy as possible, with self-test emergency lighting automatically performing tests to ensure that emergency luminaires will function correctly in the event of a mains failure. On completion of a monthly or an annual test, indicator LEDs and an audible alarm will signal the status of the fitting. Self-test options allow electrical contractors to navigate a building more efficiently, meaning the overall job is

It is a legal requirement to ensure that emergency lighting comes on in an emergency
quicker and therefore allowing them to handle more jobs in a day. The wider adoption of the Golden Thread in construction means that it is going to be more important than ever before that safety information relating to emergency lighting is closely monitored and recorded. Records of these test results, as well as any updates, faults or fixes, need to be accurately recorded and traceable in order to contribute towards creating a full picture of a building’s safety critical system. The switch to a world where the Golden Thread is fully operational may be may be faraway, in the meantime, changes to emergency lighting regulations and products will persist, but those principles of diligence and understanding the importance of emergency lighting in a wider system will remain. It’s also important for facilities managers to consider, even if your emergency lighting system is in perfect working order, whether any changes in the surrounding environment necessitate a new risk assessment. Minor structural or even aesthetic changes could affect whether there is

sufficient lighting to allow people to safely use escape routes at all times. Again, this reflects the need for greater accountability and a golden thread of accessible information, so seemingly minor changes can be judged within a wider context for any potential knock-on impact. Testing, maintenance and monitoring link back to creating peace of mind regarding whether your emergency lighting system is fit for purpose, but of course, there is a lot of work done before products and solutions are installed to help make things as easy as possible. At NVC Lighting, it’s products are all ICEL endorsed and a seven-year guarantee provided. The company’s newly branded LiFe emergency range also utilises lithium batteries, which are up to 80% more efficient than traditional alternatives, losing only 4% of their charge each month as opposed to 20% – so the company says it is confident that LiFe products will provide a long-lasting solution.

Having originally begun installing EV chargepoints back in 2019, Anthony founded e.park off the back of his successful manufacturing business Frocester, driven by a commitment to turn his passion for the delivery of a green transport infrastructure into a viable business venture. At the time, this made e.park one of the earliest EV chargepoint installers in the UK, entering the market when the number of EVs on the roads was 12 times lower than its current figure, with just 2.2 million units registered worldwide. But despite the industry’s infancy, Anthony saw the early potential of the industry, offering the ability to diversify revenue streams in what he correctly saw as a fast-emerging growth market.
It was at this early stage that Anthony realised that to stand out from competitors, e.park needed to build a reputation for providing excellent customer service beyond the initial point of install. This led him to consider software partnerships, choosing Clenergy EV as a smart charging management solution able to help customers best manage and utilise their investments. “It was all well and good getting chargepoints in the ground,” Anthony states, “but without installing them onto software, our customers would be left able to get a basic charge… and that’s pretty much it.” e.park has completed installations for a wide variety of clients in need of EV infrastructure, from retirement homes and other residential areas to individual at-home charging stations. But across this customer base, Anthony identifies that providing customers with a reliable management system was central to his customer’s experience. “Using software, commercial organisations have been able to drive changes in employee charging habits to make better use of cheaper off-peak tariffs, saving huge amounts in long-term running costs. And residential customers can do the same, with charge scheduling for these cheaper times meaning customers will be able to save money while they sleep.” “Besides that, customers need software to do simple things like set tariffs for the public to use their charge points – or lock others out for private use. And with the new government guidelines on all public-facing chargers coming in meaning operators need to provide 99% charger uptime and a 24/7 customer helpline, onboarding our customers with a software provider was an absolute must.” Will David, Clenergy EV CEO, notes the importance of software partnerships for operators needing to remain in compliance with these guidelines:
“Most operators simply don’t have the resources to man their own customer service line, or perform manual maintenance call-outs to make sure chargers are running as intended. By installing customers onto partnered software providers at the initial point of install, EV installers can focus on revenue-generating installs without compromising the customer experience.”
The offering to installers
Through the partnership, e.park can equip customers with the following features to help manage their chargers post-install:
Clenergy EV for installers • Perform quick and easy installations, backed with 24/7 support and an installer app to guide you through the installation process coming soon. • Add additional revenue streams to your business without having to take on much extra strain to your workload, by handing over post-install care to a trusted partner. • Win referrals and build your reputation by onboarding customers with reliable post-install charger support that helps customers get the most out of their investment.

EV CHARGING
POWERING AHEAD: LOCAL AUTHORITIES LOOK TO INNOVATIVE EV CHARGING SOLUTIONS The electrification of transport is a key factor in combatting carbon emissions and air pollution. Local authorities are on the frontline to make sure the transition to EV happens. One challenge they face is providing a charging infrastructure to meet the needs of a third of British households that do not have driveways or designated off-street parking.
P
ublic chargepoints will be critical to providing equal access to charging facilities and it is falling to local authorities to make this happen. While public chargepoints have more than quadrupled in four years, from 10,300 devices in January 2019 to over 51,500 at the end of October 2023, there is still some way to go to achieve the target of 300,000 public chargers by 2030. It’s important to note that public chargepoints do not include workplace or home chargers. According to research by ZapMap, there is an estimated 680,000 of these installed. The Environmental Audit Committee recently called on the government to produce a long-term funding plan for local authorities to support key environmental policy frameworks like the net zero strategy. Despite the calls for additional funding and net zero ambitions, councils lack the confidence to invest in projects like EV charging networks. That’s because of the barriers they face which impact their appetite for doing the work.
Missing opportunities
Even though there is funding available from Local Electric Vehicle Infrastructure (LEVI) funds, the complexities of upgrading and installing sufficiently powered EV chargepoints mean that many local authorities are missing out on the opportunities and also their targets.
Charging limitations
Mer brings EV chargepoints to 67 locations to make reliable EV charging accessible
Of the public chargers in place across the UK, 62% have a power rating of 3kW up to 8kW, and only 18% have power of 50kW and above. Kerbside chargers tend to be slower and installing them has limitations. They are often linked to street lighting columns that are difficult for local authorities to upgrade. Protecting kerbside charging spaces for EVs is difficult in urban areas where parking is a premium and EV charging spaces can often be ‘ICED’ – where an internal combustion engine (ICE) vehicle parks in the space.
The need to scale
The availability of public chargers will have to rapidly scale up to meet the growing numbers of EVs on the road. Installing one, two or three kerbside or car park charging bays is not going to be sufficient. Local authorities are looking for more innovative charging solutions that enable them to scale at speed in a way that doesn’t create a lot of additional work or strain on already stretched budgets.
Getting the right site
Local authorities often own land that can be used for charging ‘hubs’, rather than individual kerbside chargers. However, installing the necessary charging infrastructure can be complex and time-consuming. Finding the right location is crucial for providing local charging services. It’s important to provide the right number and type of chargers at the right locations.
Over-installing EV chargers can cause local grid strain and/or unused chargers – this is uneconomical and stranded chargers have an environmental impact.
Partnering for success
Working with established EV infrastructure partners, from contractors to chargepoint operators, pays dividends. These experienced partners can offer innovative solutions based on their knowledge and understanding of the challenges. They can provide a complete service from planning the infrastructure with you, to grid connection and supply, to installation of chargepoints.
Community Charging Initiatives
Increasingly, local authorities are exploring larger scale, mixed-speed installations to meet the different needs of their communities. Community Charging Initiatives see councils working in partnership with chargepoint operators and other partners. This is what Durham County Council embarked on with Mer and others to create the Scaling On-Street Charging Infrastructure (SOSCI). The two-year partnership saw Mer bring EV chargepoints to 67 locations across the county so that underserved communities could access reliable EV charging. Through consultation with residents, the chargepoints were strategically placed where residential demand was at its highest. The installed chargers included 70 fast chargers, five rapid chargers and two semi-rapid chargers. They use either ‘universal’ Type 2 or CCS sockets – the most common connectors on current EV models – for ease of use. The project means that Durham County Council is seen as a local authority that has taken a big step forward in building the infrastructure for EV charging and is able to better support the rural areas in its community.

EV CHARGING
THE FUTURE OF EV CHARGING In this article, Webro’s, Head of Marketing, Chris Mellor‑Dolman, and Sales Director, Chris Bacon, delve into the world of electric vehicle (EV) charging and its future developments. The article discusses the latest innovations in charging technology and looks at the road ahead for the UK’s charging infrastructure.
P
ut simply, an EV charging system is made up of several key components: An electric vehicle charger converting AC or DC power into an appropriate voltage to charge an EV battery; a power grid providing power to the charger; and a meter to measure the energy consumption. All of these components require cables connecting the vehicle and the grid. Cable is fundamental to EV charging, and development has had to keep pace with the vast array of advancements happening at lightning speed – from vehicles to charging points. There’s a greater level of product flexibility within Low Smoke No Halogen (LSNH) materials chosen to manufacture suitable cables. Improved design parameters include high performance data elements in composite EV cables ensuring improved levels of communication between the vehicles and charging points. The demand for increased charging speeds is leading to increased levels of power demand. Therefore, superchargers and some rapid chargers require increased diameter conductors to ensure efficient transfer of energy to vehicles. So, what about EV’s themselves? There’s a fast-growing demand for EV’s in the UK. One of the biggest drivers is the impending ban in 2035 of internal combustion engine (ICE) vehicles powered by fossil fuels, even though it was extended from 2030 by Rishi Sunak. Year-on-year, there’s been a 77% increase in EV registrations, with 16,200 new vehicles taking to the roads and this steep upward trend is predicted to continue at pace. As we strive towards net zero in the UK, it’s obvious that decarbonised road transport is pivotal to getting there. Electrification is the solution, however it doesn’t come without consequences – the most apparent being the impact on the existing, ageing electricity network. The existing grid is built to receive energy from a small number of large generators. The reality is that thousands of smaller electricity-generating sites are essential in creating a net zero future. In
an ideal world, the national infrastructure would be rebuilt, but the cost would be astronomical – and wholly unacceptable to most taxpayers. Key stakeholders including the government, Ofgem and the National Grid continue to explore the potential solutions which include the use of AI-powered forecasting tools. Meanwhile, network operators will invest £22.5 billion over the next five years to improve grid infrastructure and increase capacity. Aside from the obvious barrier of the increased cost to buy or lease EV’s, access to charging points is one of the major concerns for drivers, making the transititon from diesel and petrol-powered vehicles to electric alternatives. Once the switch has been made, the majority of EV users who can charge at home do so. That said, the biggest challenge involves finding readily available charging points to recharge whilst they’re on journeys. To match the exponential growth of EV sales, the Department for Transport has set a target for 300,000 chargepoints to be publicly available by 2035. At present there are around 48,000, so we’re only 16% of the way there. With more EV’s coming into use, operators are having to understand energy usage better than ever before to deliver optimised voltages. They need to be able to balance loads from more intermittent power sources such as solar and wind, enabling networks and customer appliances to perform more efficiently and free up extra capacity to support the growing numbers of EV’s that need to be charged. Utilising EV’s themselves, a concept known as ‘Vehicle-to-Grid’ or V2G (sometimes called Vehicle-to-Home or V2H) is currently being developed to harness surplus electricity. With increased numbers of EV’s on UK roads, they have the potential to act as batteries by storing surplus electricity. This is then distributed into homes or back to the grid, supporting peak time demand by providing a more balanced service, reducing peak demand by as much as 60% by 2050. Given that the V2G system makes EV vehicles useful even when they’re not being driven by bolstering the grid from cheap energy sources, it’s no surprise that it’s being championed – not least because of the reduced environmental impact.
If we’re all to make the leap of faith to sustainable transportation, the first consideration in making the transition from fossil-fuelled to electric vehicle alternatives will be the purchase, hire or lease price. The second hurdle is overcoming charging anxiety. From the availability of charging points to smart charging tariffs, consumer engagement is pivotal to the future success of EV uptake. Engaging the entirety of the UK’s driving population in altering their preferences and behaviour will depend on the deployment of major technology and incentives injecting confidence into the buyer’s decision to ‘go electric’. To realise EV ambitions, we need to focus delivery across a number of fronts. First, there are 300,000 EV charging points to put into place by 2035. Alongside that, we need to fast-track several key initiatives to ensure we have acquired balanced loads from intermittent power sources. We must remove the barriers standing in the way of connecting renewable energy to the grid. We also need to provide rewards and incentives to those who invest in renewable generation. There should also be a drive to get consumers onto smart tariffs. Finally, network providers must be empowered to do more with their infrastructure, for example, by focusing on energy storage. Fuelled by environmental concerns, legislation, and financial incentives, the transition to EV’s is well underway in the UK, and indeed globally. The challenges are considerable, but it’s no longer a case of ‘if’, but ‘when’ the masses make the switch. The road to a more sustainable transport future is in our trust. Webro, webro.com

CONNECTED HOMES AND EV CHARGING: A COMMUNICATION CHALLENGE Andrew Gaved reports on the practical challenge of building and installing a ‘connected home’. ‘Connectedness’ needs to apply to the supply chain as much as to the technology
Shutterstock
O
ne of the key considerations when planning ‘connected’ homes is how to ensure efficient communication between appliances, heating and, increasingly, EV charging – and appreciating that the requirement for better and more integrated communication applies to the suppliers involved too. A recent elemental webinar heard from Kelly Butler, Strategy Director of electrotechnical body, BEAMA, which is working on updated guidance for integrated home services with EV charging. He noted that this integration had to have customers at its heart: “What you don’t want is an external operator coming into your home and saying, ‘I’d quite like to discharge your battery because I need some extra load on the grid. But I didn’t know that you’ve already set an event to happen two hours later, to charge your car at the most beneficial time. That’s why a home energy management system is so critical here because it’s the logic that manages everything in a connected home. It could be cloud-based, it could be physical, but it’s absolutely integral to having a fully connected home and not simply little boxes of connected appliances.” Fellow panellist, James Major of buildings energy specialist HubbPro, stressed that ‘connectedness’ needs to apply to the supply chain as much as to the technology. “Newbuild properties could provide a big opportunity to look at projects more holistically between the contractors, the housing developers, the housebuilders and the utilities operators,” he said. “As we head towards an electrified world, we all know that there are challenges around the grid, particularly around peak demand periods of time. We can think about meeting that at a local level – managing demand response with connected homes, battery systems and EV charging – but at the same time, we need to think how we can manage services across a slightly bigger area rather than just a single home – so we need to think about things like community battery systems.”
BEAMA is one of the industry representatives on a working group with the government looking at how to standardise the interoperability around a home, ensuring that different technologies such as heat pumps, consumer energy management devices and EV charging all ‘talk’ to each other. Whilst the Building Regulations now mandate the installation of EV charging facilities, there is currently no minimum capacity for the charger written into the regulations, Kelly added: “What you don’t want is housebuilders putting in three and a half kilowatt chargers or something that is not much better than a 13A plug. You want to push towards higher capacity charging. But then you’re into DNO connections and three-phase connections – and how much is that going to cost the house builder?” One of the other crucial areas to get right in creating connected homes is the quality of the installations – and the panellists agreed that comes back to ensuring that the right skills are available. Given that James also owns a mechanical and electrical contracting company alongside his monitoring business, he is particularly well-placed to comment. “I think that with heating installations, it has been seen as a plumber’s job, so we need to understand where that line in the sand sits for the electrical contractor to play their role on the project,” he said. “There are still plenty of contractors in this space that don’t understand basic heating controls and it’s so important as an industry that we address that first, rather than running towards the bigger opportunity with connected homes…”
This increased opportunity for electrical specialists also translates into more opportunities to bring new people into the industry. James said, “I think for us there’s a huge opportunity now. Connected homes are so much bigger now, they’re so much more interesting…but I think that it is also important to make sure that we’re getting manufacturers on board with the opportunities as well because by bringing the manufacturers in, you’re capturing the attention of those guys training.” It is a direction of travel that Kelly agreed with. He said, “My concern on skills is less about the connectivity and more about getting the supply chain engaged with the technology of heat pumps and other low carbon technologies. We talk a lot about heat pumps, but there’s other technology like smart thermal batteries…how do you encourage installers in a very conservative market? We will be able to make a consumer case when a clean heat market mechanism comes in and we see a narrowing on costs between heat pumps and boilers. But if we don’t take the installer with us, it ain’t going to happen.”

REMEHA AIR SOURCE HEAT PUMPS SUPPORT ACADEMY TRUST DECARBONISATION PROGRAMME The Priory Federation of Academies Trust has embarked on an impressive decarbonisation programme to save an estimated total of 227.5 tonnes of CO2 annually from three of its Lincoln academies, with the support of Oakes Energy Services and nine Remeha Air Source Heat Pumps.
R
enewable energy installer, Oakes Energy Services, has collaborated with heating and hot water solutions expert, Baxi, to assist the Priory Federation of Academies Trust with its ambitious sustainability initiative to decarbonise the sports centres at a series of Lincoln academies. Sports facilities, particularly those with swimming pools, have high energy demand. The decarbonisation programme currently encompasses three of the Trust’s academies – Lincoln Academy, Witham Academy and LSST Academy – where gas boilers were previously heating the water in the pool and air handling units. Keen to cut its carbon footprint, the Trust approached Oakes Energy Services to help develop proposals to decarbonise the sports centres at the three schools. The designs, which illustrate the expected carbon savings, were then used to secure funding from the Public Sector Decarbonisation Scheme operated by Salix. In total, the design of the entire scheme is expected to save 227.5 tonnes of CO2 a year, equivalent to planting 7,000 trees.

The proposal for each academy was designed bespoke to the individual requirements in each building, but all involved retrofitting Remeha (part of Baxi) air source heat pumps (ASHPs). At Witham and LSST Academies, two Remeha ASHPs now supply all the heat demand in the building, feeding underfloor heating and radiators, and providing hot water for the changing rooms and the swimming pool plant. At Lincoln Academy, which has a larger 25m swimming pool, five Remeha ASHPs supply heat to calorifiers for the hot water system, as well as to the swimming pool heat exchanger, in what is the first phase of the decarbonisation programme. Nik Smith, Director at Oakes Energy Services, says, “We are very familiar with the Remeha brand – the products are fantastic, the design support and service from the Baxi sales and specification team is great, and the technical backup they offer is simply unrivalled.” A further advantage for the Oakes Energy Services team was the ready availability of the air source heat pumps. Nik explains, “As with all school projects, we were working to a tight, fixed deadline. Having the Remeha heat pumps

in stock was a big selling point, as we had more time to complete the project ahead of the start of the new term. “In addition to on-site technical support during the installation stage, Baxi also provided pre-commissioning support and commissioning to meet the handover date. All in all, a great service from the Baxi team.” Rob Erwood, Commercial Sales and Specification Director at Baxi, says, “The focus on low carbon design is now critical for all public sector buildings in line with ambitious government decarbonisation targets. We are proud to play a part in this project, collaborating with Oakes Energy Services to help the Trust achieve its carbon reduction ambitions with our Remeha air source heat pumps.” Remeha ASHPs are available in multiple outputs for single or cascade options, providing flexible solutions for all commercial applications. Specially designed for Northern Europe climate conditions, the Remeha ASHP range achieves a high supply temperature of up to 65°C flow temperature, making them suitable for use on new build and retrofit projects.

CUTTING CARBON To reach the 2050 net zero targets, it is vital for the UK to reduce carbon emissions from its buildings. This means the electrical industry will have to reconsider the products it specifies and installs in projects. Joe Brawn, Product and Marketing Director at Vent-Axia, explains how heat recovery ventilation can help reduce carbon emissions and contribute to a net zero future, offering a great opportunity for electrical contractors.
T
imes are changing… despite the government appearing to slow down on its route to net zero, the UK still has the legal target to meet net zero by 2050. Rather than putting sustainability on the back burner to meet these targets, it is important to make changes now to ensure we meet this goal. Buildings account for 40% of energy use in Europe and approximately 35% of emissions. To meet the government’s 2050 net zero target, buildings need to decarbonise. This involves the wide-scale electrification of heating and shifting away from fossil fuels, as well as significant improvements to air tightness and building insulation. Heat recovery ventilation will be a key technology helping to deliver other means of carbon avoidance by preventing heat loss, so as a technology it is poised for significant growth. The government has already taken measures to reduce building carbon emissions. In 2021 the government amended Part L (Conservation of Fuel and Power) and Part F (Means of Ventilation) of the Building Regulations, reducing carbon emissions from new build homes by 30%. The next step for new build homes will be the introduction of the Future Homes Standard in 2025, which aims to ensure that new homes built from 2025 produce 75-80% less carbon emissions than homes built under the current Building Regulations. However, it is not only new build homes that are affected by the Building Regulations reducing carbon emissions from non-domestic buildings by 27%. Commercial buildings are also required to meet three performance metrics: primary energy target, CO2 emissions target and minimum standards for fabric and fixed building services, with heat recovery being an ideal solution to meet requirements. In order to fulfil the necessary carbon reductions, buildings are becoming more thermally efficient due to insulation and increased airtightness to avoid heat loss. For example, airtightness is set to be a critical feature of energy efficient homes going forward, with new homes adopting the Fabric Energy Efficiency Standard to measure energy efficiency. However, an airtight building envelope should allow controlled air exchange and air

and poor indoor air quality (IAQ). Energy efficient heat recovery ventilation therefore supplies a solution that provides healthy filtered air while recovering heat that would otherwise be lost.

Energy efficiency
Specifiers of low carbon and carbon neutral buildings will be pleased to know that the latest heat recovery, such as Vent-Axia’s Sentinel Apex Commercial Heat Recovery and the residential Lo-Carbon Sentinel Econiq Mechanical Ventilation with Heat Recovery (MVHR), have been designed to be highly energy efficient with low specific fan powers (SFP) and low embodied carbon. Alongside this, they also ensure occupant comfort is a priority by operating quietly and effectively, improving IAQ. Recovering as much as 93% heat recovery efficiency, this type of unit saves huge amounts of energy that would otherwise be wasted – good news for carbon reductions. Although specifying a heat recovery unit which boasts low energy usage and high thermal efficiency is key to reducing carbon emissions, optimum installed performance also needs to be considered. This shift towards more airtight and better insulated dwellings and buildings means greater focus being placed on the installed performance of ventilation. To ensure a building operates as designed it is also vital to ensure it is commissioned accurately. To make commissioning simple, the latest heat recovery units feature advanced control systems which provide on-board, in-room and app-based control, where full functionality commissioning and monitoring is provided as standard, ensuring a unit meets its energy efficiency targets. For residential properties, manufacturers have taken one extra step to make commissioning even easier. For example, the Sentinel Econiq operates efficiently to its design intent and to help housebuilders comply with Part F (Means of Ventilation) of the Building Regulations. Vent-Axia has developed its pioneering Commissioning Wizard for the Sentinel Econiq, making it easy to commission. Available online and via a smartphone app, the Commissioning Wizard makes it very simple to comply with Part F, allowing the ventilation installer to input all the necessary information that Part F requires for compliance. It will then output a complete detailed report for building control to sign off. It is far easier than filling in a paper commissioning document on site – it is easy to use and saves time, giving peace of mind that all the necessary questions have been answered.
Energy wastage
When selecting a heat recovery unit, it is vital to choose a unit where every element has been considered to avoid energy wastage. Heat recovery featuring demand control optimises IAQ while minimising ventilation energy consumption, only ventilating when required. Demand ventilation also helps with compliance with Approved Document F which states occupied rooms in commercial buildings must have means of monitoring IAQ. CO2 demand-controlled ventilation can ensure good IAQ as per Part F. However, electrical contractors should be aware when selecting a heat recovery unit that some elements can hamper efficiency. Filters are an important element of a unit, as it is vital to maximise good IAQ
@ecn_magazine
HVAC (Vent-Axia).indd 61
SPECIAL FEATURE
high level filtration. However, filters need to be chosen wisely, as a poor choice might affect the heat recovery unit’s efficiency, resulting in a higher SFP. Another feature to consider when specifying heat recovery ventilation is summer bypass. As buildings and homes become increasingly airtight the threat of buildings overheating is growing. As well as IAQ and energy efficiency, thermal comfort is vital in our homes and buildings. However, a summer bypass is another element that can negatively affect performance. Specifiers should consider an integral automatic summer bypass designed to provide free cooling when available, while ensuring it is sized to eliminate performance loss. Sizing in general is an important factor when it comes to heat recovery. Over-specification of a unit wastes energy. Specifiers should choose a heat recovery unit that comes in multiple sizes to ensure a unit is selected which meets the necessary airflow requirements. There are free cloud-based tools available that allow specifiers to select fans to exact duty points so the fan will operate in a building as designed.
Embodied energy
As energy efficiency reaches its pinnacle there is greater focus on the embodied energy of products in our buildings. To reduce embodied energy, specifiers should look for products that are UK-manufactured with the supply chain kept as short as possible. Also, opting for a product that is completely serviceable and maintainable, so that each component can be removed and replaced if necessary, is very helpful in extending the life of a heat recovery unit. It is also important to consider the end of life of a product, ensuring it can be easily re-purposed or recycled. When designing a building to be low carbon or carbon neutral, there are many challenges to consider, from selecting materials to coordinating multiple layers of supply chain management. Obtaining accurate and up-to-date embodied carbon information is crucial for ensuring that the building meets its carbon reduction targets. However, embodied energy is a complex topic – one of the challenges is around transparency and data sharing throughout the material and building lifecycle. This can be a time-consuming and complex process, as it requires data to be collected from multiple sources, including suppliers, manufacturers and contractors. Therefore, manufacturers are now taking additional steps to provide the embodied carbon information that designers need by using CIBSE TM65 data collection methodology to collect accurate and detailed embodied carbon information. Working from a component level, this methodology ensures data is comprehensive and up-to-date. Vent-Axia is constantly improving the efficiency of products and reducing their carbon intensity. For the company’s latest heat recovery ventilation products, Sentinel Apex Commercial Heat Recovery system and the Lo-Carbon Sentinel Econiq residential MVHR, it can provide TM65 data to help customers understand their wider life cycle assessment

Net zero has been described as the ‘economic opportunity of the 21st century’. It has been said that by 2030 the supply of goods and services to enable the global net zero transition could be worth £1tn to UK businesses. In preparation for net zero, a report by the Climate Change Committee (CCC) called for stronger investment and governance in further education, particularly focusing on training the next generation of electrical engineers. The CCC report also states that with targeted intervention from the government, the net zero transition could potentially add up to 725,000 new jobs to the UK economy.This looks set to provide a huge boost to the electrical industry. Net zero is therefore good news for electrical contractors. As the government continues to try reducing the carbon emissions generated from the built environment, the drive for greater energy efficiency will continue. As a result, heat recovery will become more popular and electrical contractors able to fit the technology competently will be in high demand. Heat recovery ventilation, therefore, offers a huge opportunity for electrical contractors to undergo training to install the technology. So, when electrical contractors are considering how to ventilate a low carbon or carbon neutral building, heat recovery ventilation is a good solution to choose. By focusing on energy efficiency, avoiding energy wastage and measuring embodied energy when selecting a heat recovery unit, electrical contractors can successfully reduce carbon in buildings as we head towards UK net zero 2050 targets.

ANSELL LIGHTING UNVEILS UNIQUELY VERSATILE LINEAR LUMINAIRE
UNICRIMP ADDS METAL CABLE CLEATS TO Q-FIRE RANGE
Unrivalled functionality and versatility are the hallmarks of Ansell Lighting’s new ZLED Linear Opti-X high and low bay light. Two switches enable output to be changed between 100W, 150W and 200W and the beam to be angled between four options – 35°x85°, 95°x115°, 65°x110° and 50°x100°. This means that if there are any changes to the racking layout, or to the use of the area being lit, the lighting can be adjusted simply by altering the beam or wattage, without having to make any modifications to the fitting itself. Octo compatible, 0/1-10V dimmable as standard, and with an optional energy-saving motion sensor, the ZLED Linear Opti-X is ideal for all industrial applications, including warehouses, sorting areas and production facilities. Delivering 140lm/w, the IP65 rated ZLED Linear Opti-X has a robust die-cast aluminium construction, delivering enhanced thermal protection to optimise the LED lifespan. It comes with a five-year warranty. A 1.5m suspension kit comes as standard and surface mounting is possible with an AZPLLED/LC accessory. Ansell Lighting, ansell-lighting.com
Unicrimp has added a range of Metal Cable Cleats to its growing Q-Fire portfolio of fire-rated cable accessory products. The new Metal Cable Cleats meet BS 7671 (18th Edition) requirements and are designed to prevent cables from premature collapse during a fire and, in doing so, keep emergency services and the public safe. The 18th Edition wiring regulations stipulate that cable support systems must be constructed with materials that will withstand premature collapse caused by direct exposure to heat. There are no applications excluded – trunking, conduit and cabling fixed to surfaces of the building or attached to cable support systems must all have fire-resistant supports in place. Unicrimp’s fire-rated black Metal Cable Cleats are available in 14 different size options suitable for cable sizes from 5mm up to 50mm. The key feature of the product is an oval fixing hole which allows for cable diameter tolerances. To install the metal cable cleat, the electrician just needs to bend the cleat around the cable and fix in place to the designated wall. Unicrimp, unicrimp.com

LAUNCH OF NEW WIRELESS BMS SENSORS BRINGS ADVANTAGES TO CHANGING BUILDING LANDSCAPE Siemens has introduced three new wireless room sensors as part of its ongoing development of the company’s expanding IoT range. Wireless technology has moved on significantly in recent years and is once again starting to become a popular option in building management systems (BMS), offering several advantages over conventional wired technologies. The introduction of the wireless, battery-operated sensors enables quick and easy installation to provide important monitoring of indoor air quality (IAQ), with three options available: temperature only; temperature and relative humidity; temperature, relative humidity and CO2. With CO2 being an excellent indicator of IAQ, this new sensor offers a measurement accuracy of +/-2%. For those requiring monitoring of all three variables, the three sensors are housed in a single unit, with a temperature range of 0°C-50°C, a humidity range of 0%-100% and a CO2 concentration range of 0-5,000ppm. Open interfaces are key in enabling more intelligent room devices and building solutions. The new sensors communicate wirelessly through Thread – an open source, mesh networking, IP-based protocol – meaning they operate seamlessly, either with Siemens’ own BMS, such as the popular Desigo system, or with those of other manufacturers. Thread’s low power consumption, spread-spectrum techniques provide immunity to interference, while its self-healing properties avoid a single point of failure. This enables automated control of IAQ, with, for example, the sensor triggering increased ventilation when a predetermined CO2 level is detected, even if a router fails.

The new sensors have been three years in development and are being launched at an opportune time. With buildings being repurposed and offices being reconfigured in light of the changing building landscape post-COVID-19, the capability to easily relocate the sensors to meet new requirements without damaging walls and ceilings through re-wiring is a particular advantage. Aesthetics are further addressed through the slim new design and easy mounting options (wall, flush or tape mounting). Siemens, siemens.co.uk
