A CONVERSTION WITH PROFESSOR KEVIN KELLY

A

s we move into 2026, the Irish building services engineering sector finds itself “at a pivotal juncture”.

Insights recently shared by CIBSE Technical Director Anastasia Mylona underscore a fundamental shift: We are moving beyond the era of “design intent” into a future defined by verified performance and holistic accountability.

For Ireland to meet its decarbonisation targets, the acceleration of low-carbon heating —specifically heat pump integration and low-temperature system design — must become the industry baseline. However, the challenge is expanding. The sector must master the complexities of whole-life carbon, quantifying the embodied energy of mechanical, electrical, and plumbing (MEP) systems.

In this issue, former CIBSE President and recent CIBSE Gold Medal recipient Emeritus Professor Kevin Kelly, a true building services engineering pioneer, discusses how diversifying university pathways is no longer just a social goal but a technical necessity for solving the most complex engineering hurdles.

ASHRAE Ireland President Howard Neville emphasises the progress achieved through cross-industry collaboration. David Connelly, IDEA, outlines the blueprint for delivering district heating networks, while Eamonn Sheils, SEAI, provides direction on completing SEAI Business Energy Upgrade Scheme applications.

Ronan Power, Solar Ireland, explores the key drivers behind solar energy’s rapid growth, and Enda Ruxton offers expert technical guidance on heat meters.

Ireland’s retrofit momentum: SEAI reports record €645m grant investment in 2025

T

he Sustainable Energy Authority of Ireland (SEAI) has announced that 2025 was a landmark year for the nation’s energy transition. Figures released in January reveal a record €645m was deployed in government grants, marking the highest level of investment since the authority’s inception.

For building engineering professionals and contractors, the data signals a significant scaling up of the retrofit and renewables market. From domestic solar PV to large-scale business energy reductions, the appetite for decarbonisation is reaching a fever pitch.

Commercial and domestic highlights The SEAI’s 2025 performance report highlights a robust year for the built environment across all sectors: • Commercial decarbonisation: Over 4,500 businesses across every county in Ireland received support to reduce energy costs and fossil fuel reliance.

• Residential retrofitting: More than 58,000 home energy upgrades were completed, representing an 8% yearon-year increase.

• Solar PV Surge: 2025 was a historic year for microgeneration. Of the 102,000 homes grant-aided for solar

panels since 2018, one-third of those installations occurred in 2025 alone.

• Fuel poverty initiatives: The Warmer Homes Scheme reached a new peak, delivering free energy upgrades to over 8,000 households at risk of fuel poverty.

Driving the energy transition William Walsh, CEO,SEAI, emphasised that the momentum is driven by a desire for long-term security against volatile international markets.

He commented, “The long-term solution to high energy costs is to reduce our reliance on fossil fuels,” Walsh stated. “We must put our energy system on a more sustainable, secure footing. Last year was a record year for investment—there is real momentum now behind our programmes.”

William Walsh also noted that the “neighbour effect” is taking hold, with the visible benefits of upgrades— improved comfort levels and reduced bills—encouraging more homeowners and businesses to enter the pipeline.

The engineering challenge ahead Despite the record-breaking figures, the SEAI’s 2025 Energy in Ireland report,

published in December, suggests that there is still a significant mountain to climb. While emissions are falling, the link between economic growth and fossil fuel consumption has not yet been fully severed.

For the building services sector, the SEAI has identified the “solutions that work”, calling for a continued focus on: • Grid reinforcement and renewable energy infrastructure.

• The expansion of district heating networks.

• Continued deep retrofitting of the existing building stock.

To support this technical evolution, the SEAI awarded €22m in research and innovation funding over the course of the year, ensuring that Ireland remains at the forefront of energy research.

2026: A Year of Upskilling for Net Zero As several factors drive Ireland’s sustainability push, upskilling workforces has never been more critical.

Richard Swinburne, Managing Director, Wilo Ireland, argues that meeting the ambitions of 2026 and beyond hinges on how effectively the sector strengthens its skills base and commits to knowledge and best practice sharing.

T

he previous issue of Building Services Engineering described 2026 as the “year of net zero action”. While this referred to the mustattend trade shows lined up for the coming year, it got me thinking about how 2026 should be perceived from a skills perspective. Who wouldn’t take that thought path?

Ireland is traditionally recognised as having a skilled workforce. The definition of “skilled” will naturally differ across industries, and it seems to evolve in response to two factors: technological advancements and global megatrends, which often influence one another. The ongoing conversation around the need to “be more sustainable” is a fitting example.

This is a megatrend that has brought Face-to-face and online CPD training sessions are available on a range of topics.

– and continues to bring – several ambitious targets and subsequent regulations, driving the corporate objective of delivering value to customers in a “sustainable” manner.

Strategies like the EU Green Deal, for instance, explicitly show that the road to net zero is intrinsically linked to an organisation’s value chain and workforce capabilities. In short, the definition of “skilled” looks set to change once again…

A greener value chain The Green Deal introduces more than 175 directives that reshape energy, supply chains and sustainability reporting.

These mandates mean organisations must disclose emissions, climate risks and transition plans, to name just three, prompting the introduction of initiatives

and processes built to support the ‘green’ drive and upskill workers in the process. Similarly, in Ireland, the latest national skills strategy outlines the importance of bridging the “know-do” gap – which is the disconnect between knowing what to do theoretically and actually implementing it in practice - on carbon and environmental transparency.

Wilo’s Global Water AI Academy is a perfect example – one close to home, too. Launched in February, it intends to share both water and AI expertise across borders through a series of online modules developed alongside Edinburgh-based Heriot-Watt University.

AI-enabled water technology can boost access to clean water and strengthen food security through digital irrigation solutions. Related tools can also help teams analyse operational costs versus upfront capital, enabling better long-term decision-making and supporting more transparent conversations about carbon impact and equipment longevity.

Collaborating to catalyse net zero Why have I digressed into the ‘wonderful’ world of AI, you ask?

Because short courses focused on topics like sustainability and AI, or both, are becoming increasingly important to modern training. They enable engineers to develop relevant skills without having to commit to a long-term apprenticeship. The scale of the green transition and the speed at which it’s unfolding mean no single organisation or academic institution can keep pace alone. This is where inter-industry collaboration is crucial.

The capabilities required of those working in the building services sector seem to change daily. Whether it’s heat pump installations, digital commissioning or embodied-carbon assessments, the best way for the industry to collectively thrive and progress towards net zero is through sharing best practices.

A great example of this collaborative approach is the CIBSE Ireland workshop programme, which I read about late last year. It delivers short sessions ideal for those who need to stay up to date

NEWS AND PRODUCTS without stepping away from work for long periods. Most importantly, they create a space for open discussion, where lessons learnt on the job can be shared and fed back into best practice across organisations – even competitors.

In addition to improving the entire value chain, this can help reduce costly rework caused by misaligned project designs, which seem to occur far too often as building standards change.

These partnerships play a major role in embedding awareness of sustainable practices and carbon transparency across all skill levels, from apprentices to senior engineers.

Closing the “know-do” gap CPD programmes are another route to industry-wide upskilling. They educate installers, consultants and building service engineers on a range of applications and equipment, such as high-efficiency pumps, pressure boosting, degassing and rainwater harvesting.

Pumps, for instance, are becoming increasingly intelligent, and the training requirement now centres around interpolating functions and menus on human-machine interfaces (HMIs). To bridge the “know-do” gap, businesses like Wilo offer CPD programmes to educate engineers on how to operate and maintain such equipment to the best of their ability. They can be

Owning a collective responsibility 2026 is going to be another year defined by sustainability, and upskilling is a central pillar of Europe’s – let alone Ireland’s – net zero journey. The Keeping up to date with pump technology with hands-on product training.

continued evolution of technologies and directives curated from global megatrends demands a workforce that can adapt just as quickly. It’s also clear that isolated efforts from organisations won’t suffice either. Instead, this process will require collaboration between manufacturers, educators, professional bodies and even engineers themselves, each sharing knowledge and best practice that strengthens the sector as a whole.

Whether through CPDs, short courses, cross-industry workshops or ambitious initiatives like AI academies, there are a host of accessible opportunities available to those looking to be prepared for the coming year and beyond.

If 2026 is to become the year of net zero action, it must also be the year that we collectively invest in the skills needed to carry us there.

Engineering a greener future: Mitsubishi Electric and partners transform Bank of Ireland’s energy footprint In a landmark move toward full electrification, Bank of Ireland has transformed its mission-critical Cabinteely data centre into a model of energy efficiency. By replacing ageing gas boilers with Mitsubishi Electric’s advanced CAHV heat pump technology, it has reduced its annual carbon footprint by 120 tonnes.

A

s one of Ireland’s most established banks, Bank of Ireland faced a modern dilemma with its infrastructure. At the heart of the bank’s operations lies the Cabinteely data centre – a facility originally built in the 1970s and renovated in the 1980s. This centre operates 24/7 to support the bank’s core services.

As part of the bank’s 2030 carbon reduction strategy, the property engineering team, led by Robbie Norman, Bank of Ireland’s Property Engineering Manager, identified a number of critical needs: Decarbonise the site, eliminate reliance on fossil fuels and future-proof the building, all without disrupting its daily operations.

The facility had to move away from fossil fuels. However, the

project presented a triple-threat of challenges.

First, the retrofit had to integrate into a 50-year-old building.

Second, the solution needed to deliver high-temperature water (similar to a boiler) to match existing infrastructure.

Finally, as a live data centre, the site could afford zero downtime.

Installation had to be executed in a way that ensured zero impact on staff or services.

In a nutshell, Robbie Norman explains the project’s central objectives: “The ultimate goal of this project was to remove our reliance on gas and then reduce our impact on the environment.”

Engineering a Seamless Transition To solve this complex puzzle, Bank of

Ireland collaborated with JV Tierney & Co Consulting Engineers and Crossflow Refrigeration, a Mitsubishi Electric Diamond Quality Partner (DQP).

The project was driven by ambitious targets, removing as much carbon as possible annually, achieving full electrification and adopting low-GWP refrigerants to comply with upcoming F-Gas regulations.

After a rigorous evaluation process that weighted energy performance, reliability, and carbon impact, Mitsubishi Electric’s Ecodan CAHV system emerged as the clear winner.

L to r: Aaron O’Mahony, Project Engineer, JV Tierney; Andrew McEvitt, Applied Solutions Manager, Mitsubishi Electric Ireland; Johnny Ryan, Technical Sales, Crossflow Refrigeration; and Robbie Norman, Property Engineering Manager, Bank of Ireland.

JV Tierney, takes up the story: “We needed something that would achieve similar performance to a boiler but obviously use new technology. And the Mitsubishi Electric CAHVs can do this.”

The solution involved the installation of 12 Ecodan CAHV-R450 high-temperature heat pumps. These units are specifically engineered for retrofits, capable of delivering hot water up to 70°C notes, without the need for auxiliary boost heaters.

The Power of the Cascade A key technical highlight of the installation is the modular, cascadecontrolled design. By linking 12 units together, the system can handle variable loads with extreme precision, modulating in increments as small as 0.5kW. This configuration also provides the “mission-critical” reliability required for a data centre. Furthermore, the

use of low-GWP (Global Warming Potential) refrigerants ensures the bank is already compliant with upcoming F-Gas regulations, futureproofing the investment for decades.

Johnny Ryan, Technical Sales for Crossflow Refrigeration, notes, “Mitsubishi Electric were the perfect option for this project with their reliability and their tech support.”

Results that bank on the future The implementation was a masterclass in logistics. Despite the scale of the retrofit, the final installation took place over a single weekend, ensuring the bank’s services remained entirely uninterrupted.

The results speak for themselves.

The move to full electrification is projected to remove approximately 120 tonnes of carbon annually. For Bank of Ireland, the Cabinteely project isn’t just a one-off upgrade; it’s a blueprint for the future.

Bank of Ireland’s Robbie Norman comments, “It’s a significant step toward our 2030 strategy. We’re now hoping to replicate this installation across our other admin buildings.”

For Mitsubishi Electric, the project represents the pinnacle of collaborative engineering.

Andrew McEvitt, Applied Solutions Manager at Mitsubishi Electric Ireland, explains why the system was ideal to meet the client’s needs. “This advanced technology was chosen for its ability to deliver high-temperature hot water up to 70°C without boost heaters, making it ideal for replacing traditional boilers.

“Its modular monobloc design allowed the installation of 12 units in a cascade configuration, providing exceptional flexibility. Built-in cascade and rotation control optimise efficiency and balance run hours. The refrigerant used is T454c, which has a GWP of 148, falling within the F-Gas phase-down guidelines.

“This removes the site’s reliance on fossil fuels. When you have the right technology and the right partners, the transition to net zero becomes a reality.”

In conclusion This project exemplifies how strong partnerships drive success.

JV Tierney’s Aaron O’Mahony explains, “When you have Mitsubishi Electric and an installer like Crossflow, it just goes seamlessly.

“The collaboration between Bank of Ireland, Crossflow, JV Tierney and Mitsubishi Electric delivered a highprofile retrofit that meets carbon reduction targets, ensured operational continuity and future-proofs the building against regulatory changes,” Aaron concludes.

14 Building Services Engineering I January/February 2026

Ruth Carter, Chief Executive, CIBSE; Laura McMahon, Chairperson, CIBSE Ireland; Professor Kevin Kelly; and Vince Arnold. President, CIBSE; at Kevin’s CIBSE Gold Medal presentation at Claridge’s in London.

A conversation with Kevin Kelly From a school leaver at 15 to a global leader in building services engineering, Emeritus Professor Kevin Kelly’s career represents a landmark narrative of persistence and academic innovation. He speaks to ROBBIE COUSINS about receiving the CIBSE Gold Medal, Ireland’s untapped renewable energy potential, and his career-long mission to create a more inclusive, multidisciplinary profession.

T

he career of Professor Kevin Kelly, the recent recipient of the CIBSE Gold Medal, represents a remarkable narrative of persistence, academic innovation, and a deep-seated commitment to the evolution of building services engineering. As only the third Irish president in the Chartered Institution of Building Services Engineers’ long

history, following WR Maguire in 1901 and Eoin O Cionna in 1986, Kevin’s tenure and subsequent recognition mark a significant milestone for the Irish engineering community. His journey from an electrical apprentice in the 1970s to a Professor Emeritus and Research Fellow at TU Dublin is not merely a personal triumph but a testament to the transformative

power of lifelong learning and the strategic importance of creating flexible pathways and ladders of opportunity within the profession.

A collective success The award of the CIBSE Gold Medal in 2025 is a pinnacle in a career that has spanned over three decades of service to the Institution. Reflecting on this achievement, Kevin maintains a characteristic humility, likening his role to that of a footballer scoring a goal that was only possible because of the team’s build-up and assists.

He explains that he feels like an imposter receiving the medal until he recognises the work of all those who contributed to CIBSE Ireland and the academic team in DIT, stating that it was the team who earned it.

He adds, “The medal reflects the collective efforts of the academic team at TU Dublin and the CIBSE Ireland region over the last 60 years.

In CIBSE Ireland, the build-up began a long time ago with WR Maguire and continued through the work of influential figures like Seamus Homan and Pat Lehane. Pat, in particular, was indispensable to the region’s current

Building Services Engineering I January/February 2026 15

success.

“The academic team in the Department of Electrical Services Engineering also broke through academic barriers and the glass ceiling in creating opportunities for electricians to advance entry onto flexible programmes at honours and master’s degree level.”

Incidentally, Kevin was previously awarded the CIBSE Silver Medal in 2016. Recently, the CIBSE Silver Medal was also bestowed on Pat Lehane (2023), Seamus Homan (2018) and John Purcell (2011). Recent Irish recipients of the CIBSE Bronze Medal include Michael Curran (2024), Edward Heavey, Bill Kavanagh and Bill Noone (2016); and Brian Sterling (2015), all evidence of the high performance of CIBSE Ireland.

From apprentice to academic Kevin Kelly’s own educational journey began under challenging circumstances. Having left school at just 15 years of age in the 1960s, he recalls not responding well to the brutal corporal punishment regime of the time, which did little to entice him toward learning. However, his entry into Kevin Street College in 1971 for his first-year block release course as an electrical apprentice proved to be a turning point. The inspiring staff helped him find a love of learning.

After qualifying as an electrician, he initially spent four years studying at night gaining electrical engineering qualifications to allow him teach, while also gaining practical experience as an electrical design engineer at firms like Varmings and McGrattan & Kenny. By 1983, he joined Kevin Street as a college teacher, joining a team of innovative academic staff.

Pioneering pathways This background as an apprentice deeply influenced his later work in designing engineering academic programmes. In the early 1990s, when it was nearly impossible to gain an accredited honours degree part-time, Kevin and his colleagues forged a path at Bolton Street, on the honours

degree building services engineering programme, graduating in 1992. From this, and articles by CIBSE, a gap was identified with a lack of electrical services engineering graduates.

This led to the development of the first Electrical Services Engineering programmes in Ireland, which he led.

These programmes were international pioneers, specifically designed with “ladders of opportunity” that allowed qualified electricians to use their prior learning for advanced entry into degree programmes.

He explains, “The Irish contribution on the international stage has been and continues to be significant.

We presented at international conferences, published our work in peer-reviewed journals, and established international collaborations with universities worldwide.

“But the work of Seamus Homan and others in the 60s and 70s, particularly in the setting up of the accredited Building Services Engineering honours degree programme, must also be recognised. This work led to the huge contribution of graduates of that programme. For example, Dr Ruth Kelly Waskett [Past President of the Society of Light & Lighting] and Dr Ciara Aherne (TU Dublin) were young

engineers of the year, and both are still contributing with their research and with many other contributions to the industry.”

Kevin continues, “The team that I was part of understood the frustrations of the lack of accredited programmes and opportunities for advancement for qualified electricians. In the 90s, we set up accelerated programmes recognising prior learning (RPL) that became hugely popular. Vincent Kenny was particularly innovative in helping us seamlessly align the part-time and full-time programmes. Our part-time degree programme grew exponentially to meet demand.

At its peak, the programme was graduating over 100 electrical services engineers annually, many of whom brought invaluable practical experience to highly challenging engineering problems. There were also a number of graduates and staff who were electricians who achieved PhDs, including Dr Kevin O’Connell, a significant figure in DIT, Dr Keith Sunderland (now Registrar in Engineers Ireland), and others.”

A global voice for Irish engineering Kevin’s influence in the building services engineering industry eventually reached the global stage

16 Building Services Engineering I January/February 2026 when he became the first Irish President of SLL in 2013 and only the third CIBSE President in 2021, following in the footsteps of WR Maguire in 1901 and Eoin O Cionna in 1986.

He takes this opportunity to share an anecdote about Eoin O Cionna to offer insight into the man.

“When I became Chair of CIBSE Ireland in 2005, Eoin approached me at the AGM with a ‘to-do list’ for the committee. It was quite long.

As a new incoming chair with the usual trepidation one feels in a new position, I said to Eoin, who was quite elderly by then, that I would try to get it completed by the end of my year. ‘Oh no,’ he said, ‘You cannot wait until then, as I may be no longer around.’ Well, I just broke down in laughter, and so did he. I completed his list by half year, and he was still around for many years after that.

With many more lists annually, I am sure.”

Kevin observes that while CIBSE was historically UK-centric, or even London-centric, the Institution has shifted toward a more broadly based international organisation with over 23,000 members in over 100 countries.

He credits this transition to dynamic leadership and greater recognition of contributions from Ireland, Australia, New Zealand, Hong Kong, and the Middle East, citing research output that provided cutting-edge solutions during the pandemic.

“23,000 members in over 100 countries speaks for itself. I think that over the last few years, particularly under the hugely dynamic CIBSE CEO, Ruth Carter, there has been greater recognition of the Irish contribution and of international contributions generally.

“The current Chair of CIBSE Ireland, Laura McMahon, and the executive committee continue to keep Irish engineering at the heart of the global Institution.”

A sleeping frog Central to Kevin Kelly’s vision for the future of the industry is his response

to the challenge of climate change, which he famously illustrates through the “sleeping frog” analogy.

He explains, “While a frog might jump out of boiling water if placed in it, it will fall asleep and perish if placed in water that is slowly heated.

This is what is happening with the response to climate change.”

He is critical of the Irish government’s pace, suggesting it has been “asleep at the wheel” regarding Ireland’s vast wind energy potential.

“The engineering community needs to take a leadership role, acting as both advocates for renewable energy and experts in the design and retrofitting of buildings. Legislation must be brought forward for the greater good of the community, even when it challenges local interests, to capitalise on Ireland’s position as a potential energy-rich nation.”

His commitment to modernising the industry extends to how engineers are trained to work together. As the former Head of the School of Multidisciplinary Technologies at TU Dublin, Kevin championed modern methods of construction that emphasise collaborative team-based learning.

Dr Avril Behan led a hugely popular Master’s programme in BIM and modern construction methods from 2014, after the economic crash. It was Springboard-funded, allowing anyone out of work in the sector to achieve a Master’s degree and upskill in modern construction. It was hugely popular and combined architects, structural engineers, building services engineers, surveyors and contractors in project-based learning teams. A multidisciplinary approach not only improves industry efficiency but also leads to better building designs that reduce energy consumption and carbon emissions. For passive design to work, there must be buy-in from the entire design team, including architects and structural engineers.

However, it was not only at the upper level that the new school innovated, but it also combined all of the seven accredited honours degree

Eoin Ó Cionna, President of CIBSE 1986.

engineering programmes at first-year level.

“We combined all first-year students into a common entry system, and students could explore various engineering disciplines in first year before specialising later. This proved hugely popular with students, and the programme has gone from strength to strength, led by Kevin Gaughan, who has been course leader throughout that time.”

Breaking the “Sea of Dudes” Perhaps one of Kevin Kelly’s most vocal stances is his defence of inclusivity and diversity, particularly when he hears the term ‘woke’ used pejoratively. “Being woke is simply being aware of the difficulties others face, particularly minorities.

To be woke, one needs emotional intelligence. It is not something negative, but something that is very positive. We must not lose this battle for equity.”

“Today, Trump and seemingly a huge number of people in the United States have declared themselves antiwoke. Even the Calibri text font is banned in US government documents because it is ‘too woke’. Spare me!

“Women, too, unfortunately, are still a minority in “a sea of dudes”.

This is despite women outnumbering men in the population. This is particularly the case in engineering, where the proportion of women is

Building Services Engineering I January/February 2026 17

only 10% to 15%.

“Diversity is not just a moral imperative but a practical necessity for business survival. The best and most effective teams are diverse because business problems are multifaceted and require varied perspectives to solve them. If a team is composed only of middleaged, white, heterosexual males, the solutions will inevitably be limited and lack imagination.

“Take the car industry as one example. It designs its cars for men.

The research around car accidents centres on the use of the average man in the driving seat, when half of drivers are probably women. What a great selling point for manufacturers selling women cars to be able to say that the research focused on women as drivers. Of course, that could only happen if women were part of the research and project teams in the car company.”

During his CIBSE presidential year, Kevin Kelly oversaw the flourishing of Equity, Diversity, and Inclusion (EDI) panels within CIBSE, which he believes are essential for the Institution to remain agile and connected to the external environment.

Data centres and our ‘Goldilocks’ climate Kevin Kelly also applies this nuanced thinking to contemporary infrastructure challenges, such as the rise of data centres in Ireland.

While acknowledging the concerns surrounding their high electrical consumption, which is approaching 25% of the national total and increasing, he offers a perspective rooted in global efficiency rather than just Irish emissions. “Ireland’s ‘Goldilocks’ climate—not too hot and not too cold—is ideal for the “free cooling” required by data centres, making it one of the most energyefficient locations globally for such facilities. If data centres are a global necessity, they should be located where they require the least energy, and perhaps the associated emissions should be viewed as a shared global

responsibility rather than solely an Irish burden.”

SDAR Journal Throughout his career, Kevin Kelly has remained a champion of mentorship and professional development, qualities highlighted in the citation for his gold medal. His legacy is defined by his ability to bridge the gap between academia and industry, as evidenced by his founding and editing of the ‘Sustainable Design and Applied Research Journal’ (SDAR Journal).

“With SDAR, we wanted to publish applied research and cutting-edge ideas that were directly relevant to the building services industry.

The journal was published for ten years and has had over 72,000 paper downloads, so we certainly had some impact.”

In conclusion Even as Professor Emeritus and Research Fellow, Kevin continues to supervise and examine Doctoral students and publish research, ensuring that his influence on the next generation of engineers remains as potent as his impact on the Institution’s history.

Kevin Kelly’s story is a powerful reminder that the engineering profession is at its best when it is

inclusive, innovative, and unafraid to “lean into the discomfort” of change to build a better-functioning professional community.

Kevin Kelly is optimistic about the future.

“We have a thriving, versatile economy with a very well-educated workforce. Global change has never been more challenging, though, and we must be prepared to meet the challenges ahead. The government must ensure that we can defend ourselves and our resources and interconnections (both power and data), as a neutral country, and not be dependent on others as much.

“We have to plan for a more integrated energy system, increasing our renewable energy resources and creating storage and export markets for excess energy produced at night.

“Increasing use of electric cars and other transport can provide increased storage opportunities at night, and international connectors provide opportunity for import of electricity during low generation times and export opportunities at times of excess generation.

“And, Ireland’s shoreline as an energy resource could perhaps be compared with Texas and its oil reserves a century ago, except renewable energy will never run out,” Kevin Kelly concludes.

Panasonic drives innovation in winter heating technologies

T

his winter across Europe, Panasonic takes centre stage by providing innovative solutions to keep homes and businesses warm efficiently, sustainably, and healthily, combining state-of-the-art heat pumps, advanced smart controls, and pioneering air purification technologies.

Backed by substantial European investment and a steadfast commitment to improving indoor air quality and sustainability, Panasonic is driving the market toward a greener, more comfortable future for both residential and commercial spaces.

Heat pumps: The heart of efficient winter heating Heat pumps are increasingly recognised as the cornerstone of Europe’s transition to low-carbon heating. Unlike traditional boilers, Panasonic’s air source heat pumps extract ambient heat from the air and transfer it indoors, offering

a highly efficient alternative that can deliver up to five times more energy than they consume, with COP values reaching up to 5.3. This makes them particularly attractive for both residential and commercial applications as energy prices fluctuate and climate targets tighten.

The European Union’s REPowerEU initiative has accelerated the shift toward electrified heating, aiming to reduce dependency on fossil fuels and bolster energy security. As part of this strategy, governments across the continent are offering incentives and subsidies to encourage heat pump adoption, with installation rates rising sharply in countries like Germany, France, and the Nordics.

Panasonic meets demand To meet this growing demand, manufacturers are ramping up production and investing in local infrastructure. A standout example is Panasonic’s investment in its heat

pump capabilities in the Czech Republic, Italy and France, which will significantly increase supply capacity, training, and support across the EU. The grand opening of Panasonic’s new factory in Pilsen, Czech Republic, took place on 29 August this year, marking a major milestone in the company’s European expansion with its €320m investment. This state-ofthe-art facility is designed not only to boost production output but also to serve as a hub for technological innovation and operational excellence.

In addition to the factory, Panasonic has inaugurated the Centre of Excellence in Pilsen - a dedicated training centre, with approximately 300 sq metres of advanced learning space, aimed at upskilling installers, engineers, and partners to ensure the highest standards of product knowledge and customer service.

Complementing this initiative, the Panasonic Lab in Italy, also with 300 sq metres dedicated to both technical and theoretical learning, provides further opportunities for research, development, and hands-on training tailored to the specific needs of the European market.

Technological advancements are also making heat pumps more versatile and accessible. Modern systems are quieter, more compact,

Building Services Engineering I January/February 2026 21

modular, and capable of operating efficiently even in colder climates, a key consideration for northern Europe. Notably, Panasonic’s unique T-CAP (Total Capacity) technology ensures that the heat pump maintains its full heating capacity, delivering consistent warmth and reliable performance throughout the harshest winter conditions at even -28C (-18.4F).

This innovation addresses one of the main challenges faced by traditional heat pumps, which often see a reduction in output as temperatures fall. Combined with smart controls and integration into home energy management systems, heat pumps are becoming central to the vision of a connected, sustainable home.

Panasonic’s commitment to a greener Europe Sustainability is central to Panasonic’s heating technology, with solutions designed to reduce environmental impact through energy efficiency and smart innovation. Panasonic uses low-GWP refrigerants, including natural options such as R290, which has a near-zero GWP, supporting compliance with Europe’s F-gas regulations and helping to cut the climate impact of heating and cooling systems by addressing the significant greenhouse gas emissions associated with conventional high-GWP refrigerants.

By operating with high seasonal efficiency and integrating natural refrigerants, Panasonic’s systems are also compatible with renewable

energy sources such as solar PV, enabling homes and buildings to significantly reduce their carbon emissions while maintaining comfort and performance even in colder climates.

Smart controls & energy efficiency Smart controls are transforming heating systems by offering precision, convenience, and energy savings. Through integration with IoT platforms, smart grids, and home automation, Panasonic enables users to monitor and adjust heating remotely, optimise energy consumption, reduce peak demand, and align usage with renewable energy availability.

Panasonic offers a suite of dedicated tools and technologies to support this, including the Comfort Cloud App and Aquarea Service Cloud platforms. With the Aquarea Service Cloud app, maintenance is easier than ever, as it allows remote maintenance, ensuring the heat pump is working at its highest performance. Additionally, Panasonic offers smart thermostats for its Aquarea range, developed in collaboration with tado°. This partnership delivers an exclusive, unique algorithm and functionality.

Panasonic’s nanoe™ X Technology Enhancing Winter Wellness As winter sets in and people spend more time indoors, indoor air quality (IAQ) becomes a critical factor in maintaining health, comfort, and wellbeing. With reduced

ventilation and increased exposure to indoor pollutants, the need for air purification is more urgent than ever, especially in homes, schools, hospitals and workplaces across Europe.

Panasonic is addressing this challenge head-on with its advanced nanoe™ X technology, which is integrated into almost 80% of its indoor RAC units. nanoe™ X uses hydroxyl radicals - naturally occurring molecules known for their ability to inhibit pollutants - to actively purify indoor air. This includes reducing allergens, bacteria, viruses (including SARS-CoV-2), mould, and odours, creating a cleaner, safer environment for occupants.

A New Era for European Heating As winter approaches, the convergence of indoor air quality, sustainability, and European investment, demonstrated by Panasonic, is reshaping the heating landscape.

From smart heat pumps to airpurifying innovations, Panasonic is responding to both environmental imperatives and consumer demand for healthier, more efficient homes.

Europe is not just adapting to winter; it’s leading the way in how we heat our spaces.

Mentors and mentees who are participating in this year’s ASHRAE Mentoring Programme.

More than a network: The ASHRAE Ireland ecosystem Howard Neville, 2026 President, ASHRAE Ireland Chapter, speaks with ROBBIE COUSINS about the vital role of networking, the power of cross-industry collaboration, and why ASHRAE is a “family for life” for Irish engineers.

H

oward Neville, the 2026 President of the ASHRAE Ireland Chapter, is a much respected figure within the Irish engineering sector, whether that be in his day job with Arcadis, as an active committee member of the ASHRAE Ireland Chapter or indeed as a mentor to young engineers on ASHRAE’s Mentoring Programme.

His commitment to his craft and contribution to the HVAC sector over the years comes as a result of a perspective forged through decades of high-level mechanical design and work to improve professional standards in the industry.

At the heart of technical infrastructure His day job sees him managing the mechanical department for the Advanced Technology Group within Arcadis, a global powerhouse

that he describes as the biggest company that you have never heard of. This duality of roles—leading a department in a multinational firm while steering the course of a local chapter of an international professional body —places him at the heart of Ireland’s technical infrastructure.

Howard explains that Arcadis in Ireland has deep roots, originally operating as DPS Engineering in Cork before being acquired by the Dutch global firm in 2022. Today, the organisation is a multinational giant headquartered in the Netherlands, employing 40,000 people globally with a strong contingent of 1,000 or so professionals based in Ireland.

The scope of its work is staggering, covering everything from airports and transport systems, such as the new Dart extension in Dublin, to heavy engineering in the oil, gas, and

renewable sectors.

For Howard, however, the focus remains on the technically complex, specifically within the Advanced Technology Group. This division handles semiconductors, data centres, dry-clean rooms, and other highly technical buildings where precision is not just a requirement but a necessity for operation. He notes that Arcadis also maintains a separate Life Sciences Division, which often crosses over with his team’s expertise, creating a collaborative environment that mirrors the multidisciplinary approach he champions at the ASHRAE Ireland Chapter.

From attendee to president His journey with ASHRAE began long before he took the presidential chain of office. Howard recalls attending his first ASHRAE show in New York back in 1998, which sparked a peripheral involvement that lasted for many years from the early noughties up to starting a more engaged committee involvement in the mid 2010s.

“In 2015, I moved from having a peripheral involvement becoming an active ASHRAE committee member and I was invited to join the board in 2022.”

He was more recently appointed ASHRAE Ireland President for this year. His trajectory from a curious attendee at an ASHRAE event in 1998 to the President of the Ireland

Chapter informs his leadership style, which is rooted in the belief that the industry thrives when individuals are willing to contribute beyond their immediate job descriptions. He comments, “ASHRAE is not merely a technical society. It is a vital network that allows diverse professionals operating in the same sector to become more involved in the industry and to give something back to the community that has supported their careers.” He adds, “I am very proud to follow in the footsteps some amazing previous ASHRAE Ireland presidents and, in particular, the immediate past presidents, Edith Blennerhassett and Gary O’Sullivan.

ASHRAE: A ‘family for life’ One of the most compelling aspects of Howard’s philosophy is his view of the industry as a family.

He cites the words of another past president, Conor Murray, who remarked that ‘ASHRAE is a family for life’.

Howard explains, “This sentiment is particularly relevant in the Irish context, where the engineering sector is predominantly composed of small- and medium-sized enterprises.

While working for an SME allows an individual to gain broad experience, it can also lead to professional isolation.

“ASHRAE serves as a critical bridge, pulling people out of their organisational silos and placing them within a wider global HVACR family.

This exposure does not just benefit the individual; it allows them to bring their entire organisation along with them, introducing fresh ideas and international standards to smaller firms that might otherwise remain insular.”

Bridging the skills gap through technology transfer Howard Neville’s commitment to education and training is a recurring theme in his career. Beyond his work at Arcadis, he previously managed the skills network for Refrigeration Skillnet, where he was instrumental in upskilling the refrigeration and

air conditioning industry to meet City and Guilds 2079 standards for handling F-gases.

This passion for mentoring and teaching has always been a side part of his professional life, and it is a focus he has brought to the forefront of his ASHRAE involvement in ASHRAE’s Chapter Technology Transfer Committee (CTTC). He describes technology transfer as a fancy way of talking about education and training, “The CTCT works to identify skills gaps within the industry and address them through lectures and access to distinguished international speakers.”

ASHRAE Mentoring Programme Another committee within the ASHRAE Ireland Chapter that Howard says is making its mark is the Young Engineers of ASHRAE (YEA) programme. This is a source of

particular pride for Howard.

“While many companies have internal mentoring systems, they are often limited by internal politics or hierarchies. The ASHRAE Mentoring Programme, run through YEA, however, matches young engineers with seasoned professionals generally from different organisations, who provide a neutral and expansive learning support.

“The results speak for themselves,” Howard notes. “This year we have 15 mentees. Historically, the success rate in recent years has been phenomenal, with nearly all participants receiving promotions within a year of completing the programme.”

This initiative was so successful that the Ireland Chapter was invited to the ASHRAE World Summit in Phoenix, Arizona, to present their model to a global audience.

A seat at the table For Howard Neville, the value of ASHRAE membership extends far beyond local networking. It is about having a seat at the table where international standards are written.

He is currently involved in Technical Committee 9.11, which focuses on Clean Spaces. In this capacity, he is in the room with the very people writing the handbooks and guidance for the entire planet. He highlights the significance of the upcoming revision of Handbook 62.1, the ‘Clean Air Quality Handbook’, which is set to be published next year.

“For an engineer, being part of these conversations is invaluable, as it

provides a level of insight that cannot be found in a textbook.”

He adds that even after 30 years in the industry, he still learns something new from the monthly ASHRAE Journal, proving that the collective experience of the membership far outweighs any individual’s personal history.

Strength in the ecosystem: Strategic collaboration “Collaboration with other industry bodies is another pillar for 2026.”

Howard Neville cites the benefits of many ASHRAE members being members of bodies such as the Chartered Institution of Building Services Engineers (CIBSE), the Institute of Refrigeration Ireland (IRI) and Engineers Ireland (EI).

“Because many of our members are also members of other organisations, there are great opportunities for collaboration and knowledge sharing.”

He mentions ASHRAE Ireland Chapter board members Seamus Kerr and Michael Quinn, who hold prominent roles in IRI and EI, respectively, as evidence of this crosspollination.

“By working together on events and sharing resources, we can make the entire industry more efficient.

I believe that being part of this ecosystem is essential for anyone who wants to have a real impact, as it allows them to be active stakeholders

in the growth and development of the sector.”

Irish Engineers Punching Above Their Weight on a Global Scale The global nature of the industry is something Howard experiences daily.

He reflects on his travels with Arcadis, noting that no matter where he is in the world with work, he is rarely the only Irish person in the room.

“Irish engineers punch well above their weight on a global scale. By being part of ASHRAE Ireland, local engineers are not just members of a domestic club; they are part of the world’s largest organisation for HVACR and allied trades. This global connection provides access to a wealth of standards, handbooks, and research that is essential for modern engineering practice.”

Investing in the future: The role of sponsorship He adds, “Companies also have a vital role to play in this ecosystem.

While membership is on an individual basis, corporate sponsorship is what allows ASHRAE Ireland to invest in its ambitious programmes. Corporate support is a reinvestment in the industry’s future, particularly in initiatives like our student networks.”

In a move that is unique to the Ireland Chapter, ASHRAE student membership is fully funded, ensuring that the next generation of engineers is brought into the fold as early as

A global family for the modern engineer In Howard Neville’s’s view, with the current global climate marked by unsteady waters, the stability and collective knowledge of a body like ASHRAE is more important than ever.

He encourages anyone involved in the HVACR sector to ask themselves why they are not already involved in ASHRAE. “The benefits are clear. There is an opportunity to influence change, have access to world-class technical data, and the chance to be part of a professional family that spans the globe.”

As he leads the Ireland Chapter through 2026, Howard Neville remains dedicated to the idea that by coming together, sharing knowledge, and mentoring youth, the Irish engineering community can continue to lead the way on the international stage.

Versatile: Your Decarbonisation Partner

V

ersatile operates as a familyrun business with a clear mission: “To blend high-level engineering expertise with specialised building products.”

For over four decades, the company has built a reputation for designing and supplying the most sustainable brands in indoor climate control (HVAC), bathroomware and tiles. However, as the global imperative to address climate change intensifies, Versatile has undergone a significant evolution, recently announcing its role as a dedicated “decarbonisation partner” for its clients.

Solving the net-zero puzzle The transition to sustainable building performance is often viewed as a complex challenge that architects and developers struggle to solve without sacrificing aesthetic integrity.

Versatile’s core philosophy challenges this notion: “The path to Net Zero doesn’t have to be a challenge.”

By focusing on the seamless integration of high-performance technology into the very fabric of a

building, the company ensures that carbon reduction does not come at the expense of architectural design.

Versatile’s approach is rooted in “design-led engineering.” Whether working on a sleek, modern office development or a sensitive retrofit of a protected historic structure, it provides the essential infrastructure required to meet modern environmental standards while respecting the designer’s vision.

A Comprehensive Decarbonisation Toolkit Versatile’s transition into a decarbonisation partner is supported by a robust portfolio of low-carbon technologies. These solutions are designed to address both operational emissions and the efficiency of the building envelope: • Heat Pumps & Radiant Systems: By utilising low-temperature heat pumps and Net Zeroready radiators, Versatile helps buildings transition away from fossil fuels. Its radiant panels and climate ceilings offer energy-

efficient heating and cooling that distribute temperature evenly without the need for high-energy consumption.

• Advanced Ventilation: With a focus on Indoor Air Quality (IAQ) and energy recovery, it offers Centralised and Decentralised MVHR (Mechanical Ventilation with Heat Recovery). These systems are critical for achieving NZEB (Nearly Zero Energy Building) standards, particularly in high-occupancy environments like schools and offices.

• Precision Climate Control: Solutions such as Fan Coils, Chilled Beams, and Trench Heating/Cooling provide discreet yet powerful temperature control.

These are often used to solve spatial challenges in buildings where traditional ductwork isn’t feasible.

• Perimeter & Entrance Efficiency: Versatile’s Over Door Air Curtains and Multi-Column radiators ensure that energy loss is minimised at the building’s most vulnerable points.

For hotels, Daikin VRV 5 now offers full safety compliance ‘Game changer’ for hotel sector as factory-fitted Shirudo Technology on VRV 5 ensures no third-party leak detection required, even in small rooms

O

f the myriad commercial applications for climate control, perhaps none are quite as diverse and complex as the hotel industry.

Every hotel features multiple rooms and spaces, all with individual requirements for ventilation and air conditioning – from corridors to conference rooms, kitchens to cold rooms, restaurants to recreational spaces, as well as guest accommodation that runs the full spectrum of shapes and sizes.

For hotel consultants, architects and developers who must address the building’s air conditioning requirements in their planning, safety comes first.

The emphasis on safety in hotel HVAC planning is the driving force behind the international standards IEC 60335-2-40 and EN 378. By imposing strict safety regulations, these standards define when gas detection and alarm systems are mandatory, thus minimising the risks associated with refrigerant leaks.

This has been a significant challenge for hotel developers and planning consultants; not only the installation

of third-party detectors where necessary, but the need to assess every individual space served by the air conditioning system.

VRV 5 now 100% compliant straight out of the box Now, however, the picture may be a little clearer. A revised EU interpretation of IEC 60335-2-40 and EN 378 means that Daikin’s revolutionary VRV 5 air-conditioning system is now 100% compliant with refrigerant safety standards, straight out of the box.

Thanks to factory-fitted Shirudo Technology, no third-party leak detection is required on the awardwinning VRV 5 system – even in small hotel bedrooms.

This is a game-changer for hotel consultants, builders, architects, developers and planners, removing complexity from the design process and delivering complete peace of mind.

Daikin’s VRV 5, the gold standard of air conditioning, is now the only system in Ireland engineered to meet strict compliance and safety standards straight out of the box – no additional on-site work needed

– with built-in safety features providing peace of mind, not only for hotels but also for offices and other commercial spaces.

Purpose-built to support the decarbonisation of commercial buildings, the VRV 5 also offers renowned flexibility to fit any building as well as unmatched outdoor unit capacity, ease of installation and industry-leading CO2lowering impact.

“The in-built safety features that give the VRV 5 automatic compliance are a really important distinction in the context of Ireland’s hotel sector,” says Liam Kirwan, DX Manager with Daikin Ireland.

“The system also offers straightforward installation, maximum flexibility, and it is specifically built for lower GWP refrigerant R32, which reduces CO2 levels and enhances the energy of the building while providing a comfortable environment for hotel guests and staff across multiple rooms and spaces,” he adds.

“VRV technology was invented

by Daikin, so the technology is synonymous with the company,” Mr Kirwan says. “And thanks to factoryfitted Shirudo Technology, the VRV 5 now offers 100% safety compliance, making it the most high-performing air conditioning system on the market.”

Bridging the Gap: The case for district heating in Ireland Dr David Connolly, CEO, HeatGrid Ireland and IDEA Chair, tells Robbie Cousins why district heating is the non-negotiable backbone of Ireland’s decarbonisation and must move from the drawing board and into delivery without delay.

T

he landscape of Irish energy is at a critical juncture, particularly as the nation seeks to climb out of an unenviable position regarding its climate commitments. According to SEAI, district heating can supply up to 54% of Ireland’s building heating needs, thereby reducing carbon emissions (District Heating and Cooling Report 2022). Transitioning to district heating will play a crucial role in slashing CO2 emissions within the heating sector, propelling Ireland toward its net-zero goals by 2050.

Dr David Connolly, CEO of HeatGri Ireland and Chairperson of the Irish District Energy Association (IDEA), is candid about the scale of the challenge of delivering a district heating network in Ireland. He points out that Ireland is very much behind Europe in the share of renewable heat in any league table.

According to Dr Connolly, one of the big reasons the country remains at the bottom of the pile is the lack of district heating. He notes, “There is almost a direct correlation between the countries that have more renewable heat and the countries that have more district heating. The reason for this is that it is much easier to deliver renewable heat at scale if there is a network of hot water pipes to deliver that heat through, rather than trying to do it through individual solutions or gas grids, which are very challenging to get large volumes of renewable heat into.”

The Danish model The disparity between Ireland and its European neighbours is perhaps best illustrated by Dr Connolly’s personal experience. Having lived in Copenhagen for six years, he observed an urban population of about 1.4 million—similar to Dublin—served by a staggering 3,000 kilometres of district heating pipework. In stark contrast, Ireland’s current level of district heating, in the sense of pipes in public roads, consists of one pilot project in Tallaght with approximately 2km of pipework. This comparison provides insight into the gap between a city just starting and one that has been refining its infrastructure for 40 years.

History suggests that necessity is the mother of invention.

He comments, “While Copenhagen’s first small scheme began a century ago, the real acceleration happened during the oil crisis of the 1970s. At that time, most Danish buildings relied on oil boilers, and when supply became insecure and expensive, Denmark implemented a long-term energy plan to foster independence.

“The biggest shift was recovering heat that was being lost from power production. Much like Ireland today, Danish power stations were losing 60% of their energy to the air or nearby rivers. The massive uptake of district heating from the 1980s onwards was driven primarily by this urgent need for security of supply.”

Dr David Connolly, CEO, HeatGrid Ireland and Chair, IDEA.

Building a spine Moving from ambition to reality requires a pragmatic, project-led approach. Dr Connolly draws a parallel with his previous work in the wind energy sector, noting that large national targets were only met project by project.

“District heating will be no different. At a project level, there are natural limitations regarding affordability and risk. Typically, in areas with no existing infrastructure, projects start with a spine route of 5km-20km of pipework. This allows the first customers to be connected, usually starting with large heat users before moving to smaller ones, much like the development of the electricity grid.”

He envisions greenfield (areas without a district heating network) urban areas in Ireland, beginning with these initial networks connecting large users to a centralised heat production facility that ideally incorporates waste heat.

He adds, “Over time, these networks can be densified as smaller users join. join. Although the flagship Poolbeg project in Dublin has been discussed for two decades and is still not completed, future projects should not take that length of time.”

He highlights that, elsewhere, some projects have moved from concept to operation in just four years. So he emphasises that it is vital that Irish

Building Services Engineering I January/February 2026 37

projects move into the construction phase quickly so that the public can see the benefits.

The capital cost barrier One of the most significant hurdles remains the high upfront cost of building the first spine routes. Dr Connolly argues that because these networks are designed to last 50 to 100 years but must be paid for on day one, the initial customers cannot be expected to carry the full cost if the heat price is to remain competitive.

He describes this as a neverending chicken-and-egg scenario. “To overcome this, we need only look at the success of the 50% capital support grant in England, which offsets initial costs to a level that encourages customers to join.”

Under Ireland’s National Development Plan (NDP) for 2026– 2030, up to €100m has been allocated to support the development of district heating networks, reinforcing the country’s decarbonisation strategy. This funding aims to scale up sustainable heating, utilising waste heat and renewable sources.

Dr Connolly welcomes the recent transformation in government policy, with a dedicated District Heating Division now established within the Department of Climate, Energy and the Environment. “We are now waiting for the SEAI to finalise the terms and conditions to release funding to develop the first spines. I believe that once this is in place, we will see the first 5km-20km projects for which we have been advocating. Between now and 2030, the priority must be getting enabling funding into the market to kickstart these initial networks.”

Data centre district A unique opportunity for Ireland lies in its data centre clusters. Dr Connolly dismisses the notion that heat can only be moved short distances, noting that networks in other European cities move heat over 50km.

“Data centres present a huge opportunity to use waste heat, and since they are often located near

urban centres, they are well-placed to act as sources. Commercial buildings would play a huge role as anchor customers, getting the first pipes in the ground, allowing the network to eventually expand into smaller residential areas.

“For facility managers, district heating would be a way to outsource the heat utility. Instead of managing an on-site plant room with a gas boiler or heat pumps, a pipe delivers hot water at 80°C to the door. This allows the building manager to focus on the commodity delivered rather than the production equipment. More importantly, it offers a cost-effective way to decarbonise. Rather than upgrading individual buildings one by one, district heating decarbonises the heat source for a large network of buildings simultaneously.”

What it all means for engineers From an engineering perspective, district heating simplifies buildings.

Having a single point of connection to supply an entire building is a major advantage compared to multiple plant rooms.

Dr Connolly explains, “District heating thrives on low supply temperatures and a wide Delta T, similar to heat pumps, though district

A district heating network being installed in the UK.

heating typically supplies water at around 80°C, which is higher than what many heat pumps provide.”

He adds, “Crucially, district heating provides a path for the retrofit of older buildings. If a building connects to a network on day one, it is immediately decarbonised because it is purchasing low-carbon heat. This removes the immediate pressure to perform costly and challenging building fabric upgrades. Fabric improvements can be overseen over the subsequent decade, but the primary goal of decarbonisation is achieved from the start. This flexibility is a primary reason why so many European cities have chosen district heating as their primary tool for the energy transition,” he concludes.

As the first spine networks move from concept to construction, Ireland has a unique opportunity to turn its data centre clusters and industrial waste heat into a cornerstone of national energy security. By focusing on these pragmatic, project-led successes, the goal of supplying over half of the country’s heating needs through district networks by 2050 becomes less of a distant ambition and more of an engineering certainty.

SEAI Business Energy Upgrades Scheme: The retrofit application process simplified Getting a grant offer shouldn’t be a hurdle.

EAMONN SHEILS, SEAI Programme Manager for Commercial Retrofit, continues his series of articles on the SEAI Business Energy Upgrades Scheme (BEUS), explaining how a simplified application process is making it easier for SMEs to access grants to support their premises’ retrofit.

I

n our first article on the new SEAI Business Energy Grant, we provided an overview of the scheme and outlined its goal: to remove some of the processes of larger tailored grants that may not be suitable for SMEs with smaller buildings or retrofit projects who want to access grant funding.

Central to achieving this goal was providing a quick, easy application process for businesses, where time is a precious commodity.

In this article, we will provide a brief overview of this process to further demonstrate how fast and user-friendly

the application really is across all nine measures on the scheme.

Application Process Reviewing Options The portal is designed, as far as possible, to minimise the level of detail required for an applicant to obtain their grant offer.

For the Heat Pumps, Air Handling Unit and Pump measures, the portal goes so far as to estimate the system capacity simply from the following inputs: • Select from Drop-down: Building Type • Input: Total Floor Area

Eamonn Sheils, Programme Manager for Commercial Retrofit, SEAI.

• Select from Drop-down: System Served by new plant (eg Heating, Hot Water, etc) • Select from Drop-down: Technology (eg, VRF, Air-to-Water, etc) This allows a building owner to complete an application with basic details they will possess, aside from perhaps the System Served and Technology.

For example, in the case of the Heat Pump measures, the portal estimates a kilowatt capacity for the heat pump based on the building, total floor area and system served.

Using this result, in combination with the selected technology, a grant value is presented in the draft application along with the assumed estimated kilowatt capacity. You can also apply for FCU/ radiator and pipework replacements as part of this measure.

There is no requirement under the scheme to notify SEAI of the actual system details at this point. In addition, once the application is submitted, there is no need to contact SEAI until the project is completed and the Applicant is submitting their request for payment.

To ensure the Applicant has all these details and can complete their application in one short visit to the application portal, there is a Pre-Application Form on the dedicated webpage for each measure that mirrors exactly what will be requested on the portal.

The remaining measures (Solar Thermal, BMS Controls, Fabric Roof and Fabric Wall and Design Assistance), which cannot necessarily be estimated on building type and floor area, use a mixture of drop list selections and free text inputs. In all

Building Services Engineering I January/February 2026 41

cases, the number of inputs is kept as simple and limited as possible.

The BMS Optimisation is a flat rate of €2,000 and only requires a minimum of three systems from a list that is controlled by the existing BMS. The automatic generation of grant values allows the Applicant to try several options across all measures to obtain a grant value for same without fully submitting an application.

Contractor Selection Another unique aspect of the BEUS application portal is the Applicant’s ability to select their own contractor (ie, not on the SEAI register).

Under each measure, while the Applicant is asked to select the contractor completing the works from a drop-down list, they may enter the name and contact details of the contractor they plan to use.

In order to maintain a level of monitoring on supply chain quality, for the Applicant to be paid on completion of their works, the contractor and their associated Installer(s) will need to be registered under the scheme. However, as noted, this does not need to be completed until the Applicant is ready to submit their request for payment.

If the Applicant decides to change their contractor, registered or unregistered, after they have submitted their application, this is not an issue, once, at the time of request for payment, the final contractor appointed is registered for the associated measure(s).

Funding Options Once the Applicant is ready to submit their application, they simply fill in their bank details, review and agree to the

Terms and Conditions of the Scheme.

The Applicant will also be asked to confirm which form of State Aid they wish to apply for the grant under. The Applicant can select either ‘De-Minimis’ or ‘General Block Exemption Regulation’ (GBER).

Applicants should understand their funding options to maximise aid while staying compliant. Full details are in the Application Guide.

De-Minimis: Capped at €300,000 over three years. No energy efficiency uplift proof required; ideal for small works like pump installations.

GBER: No funding limit, but requires a 10% (single measure) or 25% (multiple measures) energy improvement. Proof is usually waived for heat pumps.

Strategy: Use GBER whenever eligible to preserve the De-Minimis budget for smaller projects such as a pump installation.

Application preparation To ensure the Applicant has all these details and can complete their application in one short visit to the application portal, there is a Pre-Application Form on the dedicated webpage for each measure that mirrors exactly what will be requested on the portal.

The Applicant’s contractor, using this form, can advise which measure options to choose. The form also includes details of the completion documentation as well as the required professional qualifications of the Contractor and Installer. Using this form in conjunction with the Company Information Form of the related measure(s) ensures all parties are aware of their responsibilities to comply with the scheme requirements.

Payment Stage Uploading Documentation Once the project has been completed and all required documentation is prepared by the contractor, the Applicant simply returns to the related application within the portal.

The applied details on each measure page will now be frozen, and an upload section of the required documents (as outlined in the Pre Application Form) is listed at the bottom of the page.

The Applicant can simply drag and drop the relevant documentation and photographs into the relevant sections and click submit.

Once all data has been reviewed and deemed compliant, the project may be selected for an on-site inspection. After successful completion of the inspection phase, the project is moved to Accounts for payment.

Final Grant Value At the payment stage, if the actual installed capacity is lower than the estimated size or provided details, the grant value can be adjusted by SEAI. If the installed capacity is higher, the grant value will not increase.

The second aspect that can impact the final payment from the initial grant value is the fact that the scheme cannot fund greater than 30% of the associated costs of the project.

As a result, at the payment stage, the final grant will be the lowest of the three values below: • Initial offer in the portal • Adjusted value due to a lower than estimated or input metrics on the application • 30% of the direct project costs for the measure.

Note: SEAI advises applicants that it is often easier to make separate applications for each measure, so that when an individual measure is completed, they can submit that particular measure for payment. If all measures are within one application, all the documentation must be input before submitting for payment for a group application.

Need for Collaboration If not, why not?

This Scheme will not succeed without the supply chain. The simple nature of the process means there is very limited input requirements for support or input from a design team or contractor, but they are a vital element to its success. We hope you can take some time to review the scheme and that you will consider promoting and encouraging your clients to engage with it for suitable projects.

Solar in Ireland: Scaling fast, with significant room to grow Last year, solar became a core component of Ireland’s electricity system. With over 2.1 GW now online, Solar Ireland CEO RONAN POWER examines the “three realities” driving this rapid expansion and explains why smarter integration—not just more installation—is the key to future-proofing Ireland’s built environment.

I

reland’s solar sector had a defining year in 2025. Not because the challenges disappeared, but because solar moved decisively from an emerging option to proven infrastructure across homes, farms, businesses and utility-scale projects.

National solar capacity passed 2 GW National solar capacity passed 2 GW in 2025, reaching over 2.1 GW by November, while rooftop solar exceeded 1 GW in December, distributed across more than 170,000 rooftops nationwide.

These milestones confirm that solar is now a core component of Ireland’s electricity system, with growing relevance for how buildings are designed, operated and future-proofed.

For the building services sector, particularly, this shift matters. Solar is no longer confined to early adopters or demonstration projects. It is increasingly being incorporated into energy strategies, cost management approaches, and carbon-reduction plans for buildings of all sizes, while still at a relatively early stage of national deployment.

Scale of Solar 2025 report Solar in Ireland is no longer a niche technology. It is infrastructure, and it is delivering at scale.

Solar Ireland’s ‘Scale of Solar 2025’ report, published mid-year, highlighted strong growth across microgeneration, commercial rooftops, auto-production and solar farms nationwide. The report estimated 2025 solar generation at approximately 1,558,570 MWh, enough to meet the annual electricity needs of more than 370,000 homes, alongside associated emissions savings of around 395,877 tonnes of CO2.

At the same time, this pace of deployment has brought the next set of challenges into sharper focus, particularly around grid capacity, skills availability, planning timelines and the policy frameworks needed to support sustained, high-quality delivery as volumes continue to rise.

Three important realities Behind the headline figures, 2025 reinforced three crucial realities.

First, rooftop solar is moving beyond early adoption. Uptake accelerated across homes, farms, schools and businesses,

driven by rising energy awareness, improving economics and greater familiarity with the technology. The scale now being delivered reflects not just demand, but the gradual build-out of design, installation, engineering and certification capability across the built environment.

Second, large energy users are increasingly treating solar as a core operational consideration. Commercial rooftops, auto-production systems and corporate power purchase agreements are being deployed to address cost volatility, decarbonisation targets and resilience. These approaches reduce peak demand, lower operational emissions, and bring generation closer to where electricity is used, an increasingly important consideration for system efficiency.

Third, integration is now as important as installation. As solar penetration increases, its value depends more on how well it is connected, managed and complemented by storage and flexible demand. This is where building services professionals play a central role, through energy management systems, smart controls, EV charging optimisation, thermal storage and battery integration.

A fast-growing sector, still building depth Ireland’s solar market is expanding quickly, but it remains at a relatively early stage compared with where it needs to be by 2030 and beyond. Grid processes, connection timelines, skills availability and planning capacity remain defining constraints. These are not unique to solar,

but solar’s speed of deployment makes them particularly visible.

This context matters as Ireland aligns with new EU frameworks, including the Net-Zero Industry Act, revised renewable permitting requirements, and the evolving Energy Performance of Buildings Directive (EPBD). These initiatives rightly raise expectations around sustainability, resilience and system outcomes. At the same time, they underline why targeted supports for households and smaller businesses continue to play an essential role in enabling participation, building supply-chain capacity and supporting quality delivery.

NZIA, auctions and the next phase of delivery One of the most important policy conversations now underway concerns how renewable support auctions evolve under the Net-Zero Industry Act (NZIA) and related EU requirements.

Future auctions will increasingly move beyond price alone to include non-price criteria such as sustainability, supply-chain resilience and innovation. This direction

is broadly supported across the sector, but implementation will be critical.

Criteria must be clear, measurable and proportionate, strengthening outcomes without introducing unnecessary complexity, cost or delivery risk at a time when scale-up remains essential.

For industry, the objective is not to slow progress, but to ensure Ireland continues to deliver renewable capacity efficiently while building the depth and resilience needed for long-term delivery.

Looking ahead If 2025 was about demonstrating scale, 2026 must be about enabling the next phase of growth.

Key priorities for the year ahead include faster, more predictable planning and permitting, grid frameworks that can keep pace with deployment, clarity on hybrid projects, storage, and private wires, and continued support for rooftop solar as part of Ireland’s evolving building stock.

These themes will also shape Solar Ireland’s 2026 Annual Conference, titled ‘Energising Life – Decarbonising How We Live’, which will focus on integration,

Solar Ireland 2026 Annual Conference, RDS, Dublin, 18 June 2026

Solar Ireland 2026 Annual Conference Energising Life – Decarbonising How We Live will be a national forum focused on integrating solar across buildings, infrastructure and Ireland’s evolving energy system. The question before us now is not whether solar can deliver, but how we ensure it continues to do so at the pace and scale required.

The theme reflects that shift. It recognises that solar is no longer

system readiness, and the practical role solar now plays across buildings, infrastructure, and everyday energy use.

Solar Ireland will also place increased emphasis on public information and engagement. As deployment expands, clear, evidence-based communication will be essential to address misconceptions and build confidence among communities, energy users and decision-makers.

A role for the building services sector Building services professionals are central to the next stage of Ireland’s solar journey.

The challenge ahead is not simply to install more capacity, but to integrate solar effectively, ensuring buildings contribute to a resilient, flexible and efficient electricity system.

Solar in Ireland is scaling rapidly, but there remains substantial room to grow.

With the right policy frameworks, skills development and system investment, solar can continue to expand in a way that delivers long-term value for Ireland’s built environment and energy system.

just part of the energy system. It is shaping how we live, work, farm and plan for the future.

Insulated Pipe Supports: More Complex Than You Think

P

ipe supports rarely grab headlines, yet they play a critical role in the performance, safety, and sustainability of modern mechanical systems. At ISOPARTNER we are acutely aware that for contractors and consultants working on complex pipe networks in Data centres, factories, schools, hospitals, and large commercial buildings, the selection of pipe support materials has become a far more significant issue than it once was.

Today we see a large increase in construction of data centres, and this has put a huge focus on process piping technology. The millions of litres of cooling fluid flowing through data centres providing cooling solutions enable quadrillions of operations per second and allow facilities to handle millions of user requests. As power densities rise and thermal tolerances tighten, the reliability and efficiency of these piping systems become critical to maintaining uptime and performance.

Any failure or inefficiency in cooling infrastructure can have immediate and costly impacts on both operational stability and energy consumption.

Sustainability is also a critical consideration in modern data centre design, particularly as cooling systems account for a significant

portion of overall energy and water consumption. Efficient piping layouts, low-loss materials, and the integration of water-saving and heat-recovery technologies can substantially reduce environmental impact while lowering operating costs. By embedding sustainability into the design phase of process piping systems, data centres can meet performance demands while aligning with regulatory requirements and long-term environmental responsibility.

A Decision Made Early – With LongTerm Consequences In most projects, the choice of pipework and associated supports is determined by design engineers during the early stages of system design. These decisions are typically informed by high-level thermodynamic and fluid dynamic calculations, focusing on flow rates, pressures, and operating temperatures.

However, the sustainability implications of getting this choice wrong can be significant. Pipe supports form a direct thermal bridge between the pipe and the

building structure. Poorly specified supports can increase heat loss or gain, introduce condensation risk, and contribute to corrosion under insulation (CUI), all of which drive higher energy consumption and maintenance costs over the life of the building.

Fire safety is an increasingly important consideration, particularly in healthcare, education, and high-occupancy buildings. Noncombustible pipe support materials such as Phenolic foam, calcium silicate, Foamglas, and microporous insulation offer clear advantages in meeting regulatory and insurer requirements.

The complexity increases further when pipe support system design is added to the equation. Supports must be capable of carrying the dead load of the pipe, the fluid, and the insulation, while also accommodating thermal expansion and absorbing vibration from pumps and fluid movement.

Crucially, changes in mechanical support performance can influence fluid and thermal performance.

Excessive vibration can disrupt flow characteristics, while insulation compression at support points can significantly reduce thermal efficiency. In chilled water systems, this can lead to condensation; in steam systems, it can result in increased heat loss and reduced system efficiency.

Material Choice: More Than Just Strength To address these challenges, designers can choose from a wide range of pipe support materials, each

Building Services Engineering I January/February 2026 47

available in different density grades.

The main objective of the support material is twofold: to safely carry the mechanical load and to minimise heat transfer between the pipe and the support structure.

Density plays a crucial role. Higherdensity materials generally offer greater load-bearing capacity, but this often comes at the expense of increased thermal conductivity. In some materials, higher density can also increase the risk of cracking or damage under thermal cycling or vibration. As a result, selecting the “strongest” material is not always the optimal solution.

Phenolic foam is widely used in chilled water and refrigeration systems due to its exceptionally low thermal conductivity and good compressive strength. It is easy to machine into custom shapes and sizes, making it well suited to complex installations. The addition of a passivation layer on the inside removes the risk of corrosion under the insulation. Operating temperature range is ~ -50°C to +110°C. Foamglas, or cellular glass, offers a unique combination of high compressive strength, noncombustibility, and complete resistance to moisture. It performs well in cryogenic and wet environments and is often specified where CUI risk is high. Operating

temperature range is ~ –260°C to +430°C PIR (polyisocyanurate) remains popular in general HVAC applications, offering good thermal performance and moderate strength.

Fire performance and temperature limits must be carefully considered, particularly in occupied buildings.

Operating temperature range is ~ –180°C to +120°C Calcium silicate is widely regarded as the industry standard for steam and hightemperature process piping. It offers excellent compressive strength and fire performance, making it ideal for demanding industrial environments. Moisture protection, however, is essential to maintain long-term performance Suitable for temperatures up to 850°C. Monolux and other microporous insulation materials sit at the premium end of the market.

They combine very low thermal conductivity with extreme temperature resistance, often up to 1,000°C. Their use is typically reserved for space-constrained or specialist applications where performance justifies the cost.

Mineral wool has a long history in high-temperature applications. Highdensity grades are non-combustible and capable of withstanding temperatures up to 650°C. However, mineral wool is not inherently load-bearing and typically requires inserts or saddles to support heavy pipework. Operating temperature range is +10°C to 250°C. Rethinking the “Hidden” Component As mechanical systems become more complex and performance expectations rise, pipe supports can no longer be treated as a secondary

consideration. Material selection must be informed by a balanced understanding of load, temperature, thermal performance, fire risk, and long-term durability.

For designers and contractors alike, rethinking pipe supports is an opportunity—not only to improve system performance but also to deliver more resilient, efficient, and sustainable buildings.

Sometimes, it is the components you never see that make the biggest difference.

Managing Heat Meter Complexity: A Fundamental Guide Greentherm Managing Director ENDA RUXTON demystifies heat meter selection, exploring essential components—from ultrasonic flow meters to LoRaWAN communications. This guide outlines critical sizing parameters, MID certifications, and installation best practices to ensure accuracy and longevity in energy efficiency applications.

H

eat meters provide a valuable tool in the energy efficiency armoury, but they’re also widely misunderstood in terms of selection and application. To get an understanding of the fundamentals, we need to view a meter under the following four elements; 1. Flow meter 2. Heat Calculator 3. Temperature sensors 4. Optional communications interface Ultrasonic Flow meter, calculator and temperature sensors (Image courtesy Engelmann Sensor GmbH)

Certifications Thermal meters sold within the European Union must have CE certification and should comply with EN 1434 parts 1-6 2022. When utilising a thermal energy meter for energy billing purposes, it should comply with the Measuring Instruments Directive (MID), a European Union directive that aims to ensure that measuring instruments used for legal purposes meet certain accuracy and

Enda Ruxton, Managing Director, Greentherm.

reliability standards. Typically, MID class 2 meters are deemed sufficient for energy billing purposes.

There are two fundamental types of flowmeters: “clamp-on”, which are non-invasive in nature and are typically used for temporary installations; and “in-line”, which are mechanically installed in the piping circuit for permanent use. For the purposes of this article, I will focus on the in-line variety.

Flow meters There are four common varieties of in-line flow meters.

• Single Jet – Suitable for low flow applications. Fluid enters through one inlet, causing a single rotor to rotate, indicating flow.

• Multijet – Utilised for moderate flow applications. Multiple jets distribute the flow, causing a turbine to rotate; it is more sensitive to low flow rates.

• Woltmann – Used for large flow applications. The fluid flow rotates a turbine housed in a chamber, using gears to translate speed into flow rate.

• Ultrasonic – Applicable for small to large flow applications.

Uses ultrasound travel-time measurement to derive flow rate with no moving parts.

Flow meters can be manufactured from brass, steel, or, in some cases, polymer materials and are generally suitable for temperature ranges of around 5C-150C ( 41F- 302F) and

Building Services Engineering I January/February 2026 49

operating pressures of up to 16 bar.

Thermal calculator This is an electronic device that comes in two varieties. The first are calculators factory-fitted to the flow meter. These calculators are often detachable from the flow meter and can be wall-mounted or similar in relative proximity to the flow meter.

They are factory calibrated as a finished product with the flow meter and come with one temperature sensor embedded in the meter and a pre-wired sensor intended to be ‘wetinstalled’ in the opposing circuit pipe.

The second variety are flow meters with a separate calculator and temperature sensors. These need to be wired on site during installation, but have the same operating principle as the pre-wired version.

Calculators can be configured for either heating or cooling mode There are three specific values of relevance that are important when selecting a heat meter: • Qp. This is the nominal or standard flow rate where the meter performs reliably and accurately over time, often used for general designation and testing.

• Qi. This is the lowest flow at which the meter can measure within its specified accuracy.

• Qs. This is the highest flow rate the meter can handle continuously and accurately.

When sizing a meter, it is important to be mindful of the above parameters as these define the operating limits for accurate measurement.

Temperature sensors Temperature sensors are available in a range of diameters, typically 5, 5.2 and 6mm. They are mostly the PT1000 variety with a normal length of 1.5 metres, but available up to around 3 or 6 metres, generally as a special order. This is an important detail when dealing with a detachable calculator, which is prewired from the factory as a calibrated item, as this limits the distance between the flow meter and the calculator.

Communication There are generally various communication options available for

Embedded ‘wet’ sensor inside an Ultrasonic Flow meter, fitted with a prewired detachable heat calculator (Image courtesy Engelmann Sensor GmbH)

heat meters. These can be divided into “wired” and “wireless” options.

The most basic wired communication method is a pulse output. This uses a volt-free dry relay contact that closes every time a set amount of energy is measured by the heat meter. This value is factoryset in the heat meter calculator, so one pulse may correspond to one kilowatt-hour (kWh) or a multiple thereof.

Meter-bus, also known as M-Bus, is a basic two-wire digital communication protocol with a low data transmission rate (baud rate).

It falls under the EN 13757 standard, which should but doesn’t always guarantee interoperability between hardware devices.

M-Bus can, in theory, have up to 250 node devices and be up to 1km in length, although the distance can limit the number of nodes and the transmission speed.

Modbus is a wired openprotocol communication method normally using an RS-485 interface.

The protocol can have up to 247 communication nodes, such as heat meters and can have a maximum network length of about 1.2 km.

Both M-Bus and Modbus can provide a digital telegram containing readings for Kilowatts (kW), KilowattHours (kWh), flow rate, and flow and return temperatures. This data is quite valuable to provide diagnostics to control systems that can help to identify system inefficiencies and fault analysis around Low Pressure Hot Water (LPHW) circuits or heat sources, such as heat pump alarms.

It is also possible to get BACnet communication modules for some meters.

The most common nonsubscription, unlicensed wireless communication options are Wireless M-bus and LoRaWAN. Wireless M-bus operates on the 868 MHz frequency, and, as the name suggests, is the wireless version of wired M-bus. It is a low data, low power, shorter range technology capable of transmission up to 100 metres in urban areas, but this is greatly reduced inside buildings. It is common to use repeater devices to ‘bounce’ the signal onward until it reaches a gateway device that brings it to the cloud. Alternatively, these devices can be read using a handheld device in ‘walk by’ mode, such as the

50 Building Services Engineering I January/February 2026 hallway outside apartments.

LoRaWAN is a newer, reliable technology that operates on the 868 MHz frequency and has a range of around 2-5 km in urban areas, reducing to hundreds of metres indoors. It is also low-data, lowpower technology, with less reliance on repeaters to get data to the cloud.

This results in much less cost risk around the rollout of metering inside buildings, making it a more attractive option.

Installation considerations Pipe sizing: Pipe diameter is often misunderstood in terms of heat meter selection. Sizing a meter solely by pipe diameter can often lead to poor accuracy and frequent oversizing, adding cost. It is important to examine the maximum flow rate and meter pressure drop, and to ensure that these are the two key parameters steering selection.

Pipe positioning: Meters configured for heating are typically factoryconfigured for installation on the return line of an LPHW circuit, because this element of the circuit is cooler, which maximises the operating life of the meter. It is possible to configure a meter for flow pipe installation, but this is usually only allowable as a one-time event, ie, once selected, it cannot be reversed.

Different types of flow meters have different pipe length requirements, sometimes on one side and other times on both sides of the meter.

These requirements are outlined by manufacturers, and, generally, ultrasonic meters require less linear length as opposed to certain mechanical varieties As a general rule, one temperature sensor is factory-installed in the flow meter as a wet sensor, ie, in direct contact with the liquid, and the second sensor is inserted into the opposing pipe work. One frequent installation mistake is when the second temperature sensor is

inserted into a dry pocket that is welded or threaded into pipework.

This results in one wet and a ‘dry’ reading, respectively, leading to an inaccurate reading.

In order to solve this problem, it is possible to specify and install wet pocket valves or weldable threaded adapters, allowing temperature sensors to be directly tapped, measuring the liquid within the opposing pipe.

Cooling circuits Using meters for cooling circuits can require careful selection, depending on the application, as not every meter is suitable for cooling. Where glycol is used for anti-freeze protection creates an additional challenge. Some meters can only be configured in 5% concentration increments, which can result in measurement inaccuracy; others offer glycol concentration measurement with automatic volumetric flow compensation.

The latter also caters for variations resulting from automatic system pressurisation and glycol top-up during maintenance.

It is essential to note the Ingress Protection (IP Rating) of a heat meter device as well as the ambient operating temperature of the electronics. It would be expected that a heat meter would at least meet a minimum IP 65 rating that would withstand ingress to the level of protection shown below.

Battery life Battery life is generally defined by the communication options and frequency of interrogation of stored measurements. The following is a guide to battery life expectancy across various scenarios.

• 20 years (without a communication module); • 16 years (M-bus, readout interval one hour); • 15 years (M-Bus, readout interval 10 minutes);

• 10 years (with others, eg, wM-bus, Modbus, LoraWAN) In conclusion While heat meters are indispensable for modern energy management, their effectiveness hinges on more than just pipe size. By understanding the interplay between flow measurement technology, calculator calibration, and accurate temperature sensing, engineers can avoid common pitfalls like dry sensor readings or oversizing.

Furthermore, selecting the right communication protocol—whether it’s the long-range reliability of LoRaWAN or the established standard of M-Bus—ensures that the data collected becomes a powerful diagnostic tool for system efficiency.

Prioritising these technical fundamentals and adhering to MID standards will ultimately guarantee a reliable, long-term return on investment for any thermal energy project.

Engineered solutions from Aalberts hydronic flow control

P

refabrication isn’t new, but Aalberts hydronic flow control stands apart. Our range of products and technologies are unmatched in the sector, spearheaded by the Flamco brand. By including other Aalberts companies, such as Aalberts integrated piping systems and their Pegler, XPress, and Shurjoint products, within our manufacturing, our product offer becomes truly complete.

The majority of components used in our engineered solutions are manufactured in-house, from within the Aalberts group. This single-source approach makes the procurement, warranty and communications process smoother and simpler.

We place as much importance on our people as we do on our products.

With decades of design expertise and experience, our engineers collaborate with your project teams in order to achieve optimal system design. This will help to achieve the seamless integration at point of install, which will offer you savings.

Our project support offer is total; from conception to completion, offering

full lifecycle assistance. This goes from the design and build stage, through commissioning and into the ongoing maintenance cycle, through our Service team.

The Aalberts offer Our prefabricated offerings cover projects of all sizes and complexities, with bespoke solutions available as: • Containerised plant rooms • Skid-mounted packages • Smaller “engineered to order” units Historically, our specialism has been in the pressurisation and expansion sector, combined with air and dirt separation and degassing technology through the Flamco brand. Plant performance is vital to keeping a site running, and our experts work with you to ensure resilience and dependability. Stable system pressure and optimal water quality are key, and successful management of these will enhance system reliability and, therefore, your reputation.

Added savings Off-site engineered solutions deliver more than simple convenience; measurable savings can be found, too, by: • accelerating speed of build (versus traditional build), helping your programme stay ahead of schedule • reducing on-site activity, reducing labour costs and time-consuming installation work

Combined, these benefits translate into commercial cost savings across your project.

Health and safety benefits Using off-site manufacture allows acceptance and compliance testing before delivery, ensuring quality, while also reducing site risks. A safer environment means fewer delays, less chance of downtime, and fewer opportunities for accidents. This will ultimately help to keep projects running smoothly, from start to finish.

On-site advantages Whatever the size of your solution, reliability comes as standard. Our systems are designed to be ‘seamless’, even the largest and complex containers arrive with the ‘plug and play’ methodology, helping your teams to get set up quickly and efficiently. The ability to pre-commission off site further streamlines seamless integration on site, saving more time during installation.

Engineering Europe’s sustainable future through circularity Circularity and advanced materials are no longer just abstract goals—they are the new engineering imperatives for a competitive Europe. With the Circular Economy Act and Advanced Materials Act on the horizon for 2026, MIHAI BARCANESCU, Policy Manager, Federation of Engineering Consultancy Associations, outlines why consulting engineers must lead this shift, integrating lifecycle data and modular design to bridge the gap between ambitious EU policy and sustainable reality.

T

he European Commission’s 2026 Work Programme sets an ambitious course for sustainability, with circularity and advanced materials as part of its pillars. For consulting engineers, these initiatives are more than policy; they

represent a fundamental shift in how we design, build, and maintain the built environment. As the Federation of Engineering Consultancy Associations (EFCA), we welcome the Commission’s ambition in this

direction and see it as an opportunity to lead the transformation towards a resource-efficient, resilient Europe.

Circular Economy Act – A turning point for construction Expected in Q3 2026, the Commission’s proposal for a Circular Economy Act aims to harmonise rules across the EU, strengthen the single market for circular products, and accelerate the transition to a valuebased approach to resource use.

EFCA’s view is that the future legislation on circularity must emphasise clarity and uniformity, sector-sensitive frameworks, and prioritise waste prevention and reuse over recycling.

More specifically, EFCA’s key recommendations are that the Act must directly implement or quickly lead to: common metrics and standards for circularity, to ensure comparability and transparency; adaptive design principles enabling refurbishment, remanufacturing and urban mining; circular procurement strategies that reward lifecycle thinking and industrial symbiosis.

Furthermore, it is essential to establish clear rules on liability

and risk allocation to encourage innovation without disproportionate burden.

For engineers, all these aspects mean integrating circularity from the earliest design stages – selecting materials for durability and reuse, planning for modularity and embedding lifecycle data into project workflows.

Advanced Materials Act – Innovation meets sustainability Scheduled for Q4 2026, the Advanced

Materials Act aims to complement the EU circularity framework by fostering innovation in materials science while ensuring safety and sustainability. EFCA advocates for a strategic EU framework that balances competitiveness with environmental responsibility.

Our federation believes that this Act should first ensure harmonised standards and streamlined regulation to reduce fragmentation and accelerate adoption. An additional requirement is to promote open innovation ecosystems and digital infrastructure for lifecycle data, enabling traceability and recyclability.

Finally, it is necessary to promote investment in skills development, to equip engineers for both emerging technologies and sustainable practices.

In a nutshell, advanced materials must be designed for reuse and recyclability, reducing dependency on critical raw materials and supporting Europe’s climate goals.

Implications for consulting engineers These legislative initiatives present both opportunities and challenges.

European engineers can lead by championing circular design, integrating advanced materials into projects, and leveraging digital tools for lifecycle management, thereby

“Circularity and advanced materials are not abstract ambitions—they are engineering imperatives for a resilient, competitive, and sustainable future.” ensuring compliance and efficiency.

They also bring added value via their engagement in standard-setting processes and advocating for fair procurement models, based on their extensive knowledge and experience.

Challenges also remain – regulatory complexity, investment barriers and skills gaps. Yet proactive engagement can position our profession at the forefront of Europe’s sustainable transition.

Circularity and advanced materials are not abstract ambitions—they are engineering imperatives for a resilient, competitive, and sustainable future.

In conclusion Circularity and advanced materials are not abstract ambitions but political, economic and engineering imperatives. By embracing these principles and enshrining them in legislation, European consulting engineers can deliver projects that are not only technically sound but also aligned with the EU vision for a resilient, competitive and sustainable future.
