reland’s Building Services Engineering sector navigates a complex landscape in 2025. The drive for sustainability necessitates innovative solutions, demanding expertise in low-carbon technologies and energy-efficient design and greater collaboration and understanding across supply chains. Retrofitting older buildings, for instance, presents a significant hurdle in balancing preservation with modern performance standards. A looming skills gap requires engineers proficient in BIM and digital design tools, compelling companies to invest more in training and development, and growing geopolitical and economic uncertainties add further complexity.

Engineers must expertly navigate these challenges while delivering high-quality, sustainable projects.

As the new editor of Building Services Engineering, I look forward to continuing this publication’s long tradition of working closely with industry bodies and stakeholders to facilitate discussion while also delivering the latest news, innovations and advances of the sector.

NEWS AND PRODUCTS

(L to r): Domnick Ward, Managing Director, Crystal Air Ltd; Masami Kusano, Living Environmental Systems President, Mitsubishi Electric Europe BV; and David O Brien, Contracts Director, Crystal Air Ltd.

Crystal Air Holdings Limited acquired

by Mitsubishi Electric Europe BV Mitsubishi Electric Europe BV has announced that it has concluded an agreement with Irish air-conditioning installation and maintenance company Crystal Air Holdings Limited to acquire all of the shares in the company.

Crystal Air’s sector expertise, paired with its installation and maintenance capabilities, will boost Mitsubishi Electric’s strategic business offering and ensure the company is well-positioned to respond to increased demand in IT cooling and data centre solutions across Europe.

The acquisition of Crystal Air follows Mitsubishi Electric’s establishment of Mitsubishi Electric Hydronics & IT Cooling Systems SpA (MEHITS), which specialises in applied air-conditioning solutions for comfort, process, and IT cooling.

Shinji Kurita, CEO and President, Mitsubishi Electric Europe BV, explains: “Through the establishment of MEHITS, and now with the acquisition of Crystal Air, we have created a strong platform to meet the growing demand in the data centre sector.

By integrating our traditional HVAC products with advanced applied solutions and a comprehensive service and

maintenance capability, we have significantly enhanced our offering to drive business growth and strengthen our presence in the data centre market.”

Ciaran Moody, Branch President, Mitsubishi Electric Europe BV Irish branch, says: “We in Ireland take immense pride in our business solutions partners, and we are particularly proud of Crystal Air’s success in delivering their exceptional expertise to the European market, especially their proven excellence in the data centre sector. This acquisition aligns seamlessly with our pan-European strategy to offer a comprehensive suite of services, including product supply, installation, and maintenance. We believe our strategy is fully aligned with the evolving needs and expectations of data centre owners and operators.”

Domnick Ward, Managing Director, Crystal Air, explains: “Combining Mitsubishi Electric’s manufacturing and product expertise with our specialised knowledge positions us uniquely in the market. This partnership enables us to capitalise on growth opportunities and further strengthen our presence in the European

data centre sector.”

Owned and operated by engineers for 28 years, Crystal Air is an established and leading provider of cooling services for data centres in Europe, providing primary cooling systems for data halls, secondary systems for switch and battery rooms, as well as tertiary systems for administration and staff areas.

Like many other Irish engineering firms delivering data centre services, Crystal Air’s reach stretches to the Netherlands, Belgium, Germany, Finland, Denmark, Sweden, Norway, and Switzerland.

Ciaran Moody adds that while the acquisition will strengthen Mitsubishi Electric Europe’s position to deliver its cutting-edge technology to data centres in Europe, locally, Mitsubishi Electric (Ireland) will continue to have the same relationship with Crystal Air that it enjoys with all of its Business Solutions Partners and Accredited Installers.

Ciaran explains: “The synergy between Mitsubishi Electric Europe’s and Crystal Air’s operations will enable us to effectively deliver our cutting-edge IT cooling and data centre technologies to clients across Europe.

The acquisition, which was completed on 18 December 2024, is subject to approval by the Irish Competition and Consumer Protection Commission.

EFCA Barometer indicates strong market starting to level out The latest European Federation of Engineering Consultancy Associations (EFCA) Barometer published at the end of 2024 offers some insight into conditions in the European consultancy and engineering industry.

The Barometer shows a currently strong market, but it is beginning to level out.

While significant new growth is not anticipated in the immediate future, most firms report robust order books and positive market conditions, which are being supported by key sectors such as energy and transport. Challenges such as staff shortages and bureaucracy remain, but the industry is adapting effectively.

Key issues Order books are strong, and profitability is up, but a shortage of staff is a key challenge.

The majority of European consultancies report good market conditions and a positive outlook for the next six months.

They do not see significant new overall growth but expect strong market

conditions to continue.

The main challenges for the consultancy and engineering industry in Europe are a shortage of staff and bureaucracy. Low fees, labour costs and political uncertainty are other challenges for the industry.

The EFCA Market Index shows the overall development of European markets. The report shows a levelling out of the markets, with a decline of 0,8 points. Ninety-four percent of the participating countries are currently reporting stable or increasing markets.

The industry is growing. The EFCA employment index increased by 30 points since the spring of 2024. But the index is forecast to decline as markets are levelling out.

A total of 56% of participating countries in the survey are expecting increased turnover in the coming six-month period, and most others are expecting a status quo.

Resilience is a key driver for growth (energy, transportation, water, manufacturing and defence).

Profitability of European engineering firms has increased significantly from 5.4%in 2022 to 7.5% in 2023. The average level from 2013-2022 is 6.0%, which means that 2023 has seen a significant improvement, not only on previous years, but also compared to the long-term trend. The fact that order stock was high in 2022-2023 and the shortage of staff was significant can have driven up earnings and hourly fees despite inflation and increasing labour costs.

The survey was conducted in OctoberNovember 2024, with 17 EFCA member associations (61%) responding.

NEWS AND PRODUCTS European countries failing to make heat pumps affordable

According to the European Heat Pump Association (EHPA), new research shows that nearly all European countries can bring in more fiscal measures to support the uptake of heat pumps, essential to decarbonising heating and cooling.

Only six of 30 countries examined set a lower VAT rate on heat pumps than on fossil fuel boilers: Belgium, France, Ireland, Portugal, Romania, and the UK. Paul Kenny, Director General, EHPA. To make the running costs of the heat pump competitive, the cost of electricity should be at most twice the price of gas. Heat pumps use much less electricity than boilers do gas to produce the same amount of heat.

Despite this, VAT on gas and electricity is the same everywhere, except Latvia and Spain, where the rate on electricity is lower.

Paul Kenny, Director General, EHPA, said: “ Every heat pump installed in Europe supports Europe’s energy security and energy sovereignty. Member states must use all the fiscal tools at their disposal to ensure this happens, with support from the EU.” The EHPA contends that the EC can kickstart this process via its upcoming Electrification Action Plan, Action Plan for Affordable Energy Prices, revision of the Energy Taxation Directive and Citizens’ Energy Package.

ARTIFICIAL INTELLIGENCE (AI)

EFCA issues a wake-up call to address the energy consumption of emerging digital technologies The European Federation of Engineering Consultancy Associations (EFCA) recently published a paper titled ‘Carbon-neutral and Responsible AI: The Energy Efficiency Challenge in Emerging Digital Technologies’.

The paper explores the challenges posed by the exponential growth of artificial intelligence (AI) in energy consumption and proposes recommendations to address them.

The imminent exponential growth in the use of AI by governments, businesses and citizens is creating an unprecedented demand for energy, mainly by the ‘Big Tech’ companies, whose consumption is said in a recent paper by Tractebel and RED to be equivalent, collectively to that of some developed countries.

The EFCA paper proposes a number of recommendations to improve energy efficiency.

Software providers • Stop the requirement for users to store their data in the provider’s cloud, thus enabling the use of just one cloud for such storage.

• Focus on interoperability and open standards – less “waste” from multiple, unnecessary use of relevant processes and duplication.

Construction and engineering firms • Improve the collaborative use of BIM so that only one model is used and shared, rather than all players in the value chain creating their own model. This is wasteful and increases energy use unnecessarily.

• Design in energy efficiency at the beginning for new data centres, so that they are already green. Consulting engineers can help with low-carbon design.

Big Tech companies/data centres/ software providers • Energy saving processes such as ‘evaporative cooling’, which (like human sweating) enables cooling of computers and the buildings in which they are being used, by water evaporation.

This method is cheaper than other cooling systems and also better for the

environment.

• Transfer of waste heat generated by computing processes and servers to other uses (examples: aquaculture, drying in industrial processes, domestic heating). This way, there is a kind of industrial symbiosis.

• Ensure that new data centres have been designed for maximum energy efficiency. Public sector owners/users of data centres should insist on this in procurement, and private sector owners must act responsibly by choosing lowcarbon designs.

• Better scheduling of back-up cycles for servers. Even though these are not the most energy intensive processes, they are easy to make more efficient, so worth improving.

• More efficient use of servers to ensure that they always run at full capacity, thus minimising the overall impact of AI by tackling the energy consumption at source.

The EFCA paper is a wake-up call to address the energy consumption of AI and other emerging digital technologies. By taking action now, we can ensure that these technologies are developed and used sustainably.

Kirby opens €8m Laois facility for offsite manufacturing Kirby Group Engineering’s Mark Flanagan (left)

Kirby Group with Enterprise Ireland Chief Executive Leo Engineering has opened Clancy at the official opening of Kirby’s offsite a new offsite manufacturing manufacturing facility in Portlaoise.

(OSM) facility at Junction 17 National Enterprise Park in Portlaoise, Co Laois. The €8m development is set to create 50 jobs. It will be critical to the company’s continued growth as it manufactures a range of components for projects across Ireland, the UK, and mainland Europe.

Kirby employs over 1,800 people and has developed a first-class reputation in the life sciences, data centre, industrial, power and renewables sectors. The Limerick-headquartered firm is on track to record revenue of more than €700m in 2024.

Over 20 people are already working at the Portlaoise facility, and Kirby expects that figure to reach 50 by the end of the year. The facility team provides fabrication, welding, engineering and BIM (Building Information Modelling) services. It also features a dedicated cleanroom to facilitate high-purity pipework, as required by many of Kirby’s hi-tech clients.

Kirby Group Engineering then CEO Mark Flanagan, who recently was appointed Group Executive Director, said offsite manufacturing (OSM) is in high demand among its customers, including a number of global IT leaders. “OSM provides incredible savings when it comes to hours on site, equipment on site, scheduling control, quality control and, of course, health and safety.

Sligo Park Hotel’s investment in PV panels could cut annual bills by €25,000

L-r: Gerard Moore, General Manager and Director, Sligo Park Hotel; James Loughlin, Cool Air; and Graham Semple, Deputy General Manager, Sligo Park Hotel.

Sligo Park Hotel has completed the installation of a new photovoltaic (PV) solar panel array on the facility’s roof, which is expected to cut the hotel’s energy bills by more than €25,000 annually and significantly reduce its carbon emissions.

JV Tierney and Company Consulting Engineers engaged Cool Air Ltd to install the 400 PV solar panels across 13,000-sq ft of the building’s roof between June and August last year. Cool Air estimates installing PV solar energy infrastructure will cut the hotel’s annual emissions by more than 47 metric tonnes of CO2. In terms of reducing atmospheric carbon, the total is the equivalent of planting 1,869 new trees yearly.

While the PV solar panels contribute less during the winter months, it is estimated that solar energy will make up 35-45% of the hotel’s overall usage from April to September. The average contribution across the year is projected to be more than 20%, leading to an annual saving of €25,000 on the hotel’s energy bills.

Where Sustainable Living Meets Modern Comfort with Mitsubishi provide an innovative, stylish and Electric’s Ecodan Heat Pumps compact single fan unit. The outdoor

M

erepark housing development is the latest addition to the Altidore Gardens community, located in Newtownmountkennedy, County Wicklow. Central to this development is a focus on sustainability, innovation and connectedness to the scenic surrounding beauty of the Wicklow mountains.

With a total of 154 houses in this development, it was important to get the heating and domestic hot water systems just right. D/ RES, the developer and one of Ireland’s leading sustainable private housebuilders, wanted to create energy efficient homes that would provide the homeowner with both comfort and reliability.

Mitsubishi Electric collaborated with McGuinness Mechanical, a leading mechanical engineering contractor, from the earliest stages of this project’s inception to achieve this.

The McGuinness design team worked closely with Mitsubishi Electric throughout the project’s lifecycle,

collaborating on site visits, designs, heat loss calculations, selections and sizing the units.

With the goal of sustainable living with modern comfort, Mitsubishi Electric Ecodan heat pumps were the perfect fit for the housing development. Ecodan Heat Pumps are the renewable, low carbon alternative to traditional high carbon heating systems, and provide reliable, renewable heating technology that delivers highly efficient sustainable space heating and hot water all year round.

“Mitsubishi Electric has reliability, green credits, sustainability and that sort of background to it and we felt that a partner like them with their knowledge, their background, their historical track record that’s really what we were looking to partner with”, says Brett Chrystal, Head of Sustainable Design at D/RES Properties All homes were fitted with a 6kW Split Mitsubishi Electric Ecodan Heat Pump. The Ecodan outdoor units

unit upgrades freely available heat energy from the air and transfers it to the home to provide space heating for radiators and/or under floor heating. It utilises advanced technologies to deliver improved efficiencies. However, an Ecodan is not only highly efficient; it is also one of the quietest units available on the market.

Each property was fitted with a 170L indoor unit. These indoor units handle the space heating and DHW demand. An Ecodan provides the home with a continuous supply of hot water via a dedicated hot water cylinder - just like a standard boiler.

With an Ecodan Heat Pump, there is a range of controls to choose from including an advanced wireless controller. A simple room controller allows the homeowner to control their own system and monitor its performance remotely. With the MELCloud Home App any smart device can be connected and control the heating and hot water locally, contributing to the overall efficiency of the property and giving tailored comfort to each household.

However, for the homeowner the Mitsubishi Electric journey does not stop once the site is finished. All the household units are registered to the INSTALL ME App, meaning the homeowner will get a notification when their unit is due to be serviced. To ensure maximum performance from an Ecodan Heat Pump throughout its working life, the system needs to be regularly serviced and maintained. Service can be provided by the installer or by Mitsubishi Electric.

Cool Careers:

Towards streamlined and accessible refrigeration apprenticeships and training Margaret Rafter, Consultant Sales Engineer, Mitsubishi Electric Europe, is the newly elected President of the Institute of Refrigeration Ireland (IRI). She speaks with Building Services Engineering about the importance of STEM education, refrigeration as a career opportunity, and the central role that refrigeration manufacturers and engineers have to play in achieving sector sustainability and carbon reduction objectives.

M

argaret Rafter, Consultant Sales Engineer at Mitsubishi Electric Europe BV Ireland Branch, has been elected President of the Institute of Refrigeration Ireland (IRI). Margaret is the first female in the role but has been a prominent and active IRI Council member for many years.

She previously sat on the events, membership and service engineers committees, and is a regular speaker at industry-related events, including the IRI annual conference.

However, Margaret is perhaps most passionate about education, promoting refrigeration as a career opportunity, apprenticeships, and continuous professional development for those already in the sector.

STEMAZING Hence, her involvement in STEMAZING, an initiative devised by Alex Knight, a chartered engineer

who had worked in the science, technology, engineering and maths (STEM) industries for over 15 years.

Through being on the IRI Council, Margaret is also a member of the Institute of Refrigeration (IOR) in the UK. Through that, she was nominated to take part in the first STEMAZING Academy course rolled out in Ireland in 2023.

The programme comprised six live STEM sessions delivered to a group of nine- and 10-year-old boys and girls at Scoil Maelruain Senior National School in Dublin 24. Each week, the children took part in a 40/45 minute activity using basic resources for the STEM activities and experiments involved. These included simple things like paper, Sellotape, a balloon, pipette, vegetable oil, food colouring and straws.

Margaret delivered all sessions to showcase a strong female role model, with Mitsubishi Electric

providing some additional resources, not to mention the goody bags for the children on the final day. Under her guidance and direction, the children created their own STEM masterpieces each week and received certificates on completion.

Just before Christmas 2023, another STEMAZING initiative, again supported by Margaret and Mitsubishi Electric, was held on HMS Caroline in Belfast. This was on open day on board the ship, where children were exposed to inspiring engineering-led activities.

STEM for children Margaret Rafter comments: “It is critical that we introduce children to the STEM subjects at an early age”, says Margaret, “and in a way that the sessions are live, educational, interactive, interesting and simple for the particular age group. They must also be fun.”

She adds: “However, having attracted them to the sciences, and in our case refrigeration,

Building Services Engineering I January/February 2025 25

it is essential that we have the structures in place to deliver apprenticeship programmes that are fit for purpose and easily accessible. There are currently a number of refrigeration training course providers throughout the country, but I would like to see a more coordinated and streamlined approach to maximise the impact.

I’m confident that, working together, we can achieve that.”

IRI Programme Looking at the bigger picture, Margaret Rafter aims to build on the work of previous IRI presidents who have established strong links with other sector bodies.

“On the broader front, I want to build on the achievements of my predecessors and forge even stronger relationships with other industry associations, government About the Institute of Refrigeration Ireland The Institute of Refrigeration Ireland (IRI) is a professional membership body that represents refrigeration and airconditioning professionals in Ireland.

More often than not, heat pumps and solar panels are, quite rightly, highlighted as some of the primary routes to achieve that.

However, lighting also has a significant role to play, and that is something that is often overlooked and underestimated, according to the Lighting Association Ireland (LAI). Gavin Edwards, Chair of LAI, urges legislators, statutory bodies, architects and consulting engineers to look at lighting with a fresh perspective.

“Lighting obviously enables vision, helps people navigate their surroundings and makes them feel safe”, says Gavin Edwards, “but it also does so much more.

“For instance, the concept of smart buildings is very much to the fore in the pursuit of energy savings, carbon reductions and sustainability, and smart lighting is a major component of that process.

Smart lighting enhances building performance and introduces key metrics for evaluating smart

technologies.

“Smart lighting systems intelligently respond to occupant needs and environmental changes, optimising energy efficiency and improving comfort. By adjusting light levels based on daylight and occupancy, these systems significantly reduce energy consumption while creating tailored lighting to suit how a building is used. Smart lighting will also prove invaluable when assessing building smartness through rating schemes, including the forthcoming Smart Readiness Indicator (SRI), which will reward buildings with advanced lighting controls.”

Gavin Edwards adds: “Smart lighting also promotes wellbeing and productivity with independent studies demonstrating how adaptive lighting transforms spaces into comfortable and sustainable settings.”

Human-centric lighting – especially when combined with smart controls – provides the right light at the right place and the right time. Tailored systems can be designed for different types of buildings, be it a domestic setting, school, hospital, office or outdoors.

“In addition to driving energy savings, carbon reduction and wellness, lighting is also a sustainability champion and very much to the fore when it comes to product circularity. To optimise every aspect of a product’s lifecycle, lighting manufacturers consider everything from raw material extraction through to manufacturing processes, first use, multiple uses thereafter and final end-of-cycle material disposal.

“To drive home this message, LAI is a proactive organisation that

Gavin Edwards, Chair, Lighting Association Ireland.

regularly engages with statutory authorities in Ireland, such as SEAI, professional bodies such as the RIAI and CIBSE Ireland, WEEE Ireland and various European legislative bodies.

Indeed, through our membership of Lighting Europe our delegates make a significant contribution to the formulation of EU lighting regulations that subsequently become law.

“Nonetheless and despite the foregoing, LAI believes that the contribution lighting currently makes, and can continue to make, in pursuing Ireland’s sustainability goals and obligations, is often underestimated. I urge all those responsible for the design and installation of both indoor and outdoor lighting projects to consult a lighting expert when doing so. The outcome will be a lighting solution that is energy efficient, costeffective, sustainable and regulation compliant.”

MTU digital substation set to advance Ireland’s energy transition and power engineering expertise

M

unster Technological University (MTU), in collaboration with H&MV Engineering and ABB, has launched a digital substation in the Power Academy Lab of its Bishopstown campus.

The investment of the digital substation is part of H&MV Engineering’s and ABB’s sponsorship, worth more than €200,000, and aims to further develop the training and research capacity of Ireland’s grid infrastructure.

The introduction of digital substations as part of Ireland’s grid infrastructure upgrade is essential for the state to meet its energy transition goals, which target becoming carbon neutral by midcentury with an interim target of 51% reduction in emissions by 2030 through the Climate Action Plan 2023 (Cap2024). Ireland’s power system has achieved 75% integration of renewable energy sources and plans to increase this to 95% by 2030, highlighting the importance of state-of-the-art grid technologies.

Irish electricity demand is also increasing rapidly with increased population, industry and data centre consumption and the transition to electric heating and transport. Total demand is projected to rise from 33

terawatt hours (TWh) in 2022 to 56 TWh by 2030 and 80TWh in 2050. To support this growth the electricity grid requires significant upgrades with a growing need for skilled professionals in designing, developing, and operating modern grid systems.

The introduction of the digital substation at MTU positions the college to upskill industry professionals from all sectors of the power engineering sector, including generation, distribution, transmission, and consumption to design, develop, commission, and operate the grid infrastructure required for the country’s future development.

Commenting on the investment, Dr Martin Hill, Head of the Department of Electrical and Electronic Engineering, stated that the industry support came at a critical time as the digital technologies in modern substation design required engineers to span both electronic, communication and electrical engineering domains at a level not previously supported in university programmes. “This equipment allows students to work in an industry-standard environment with the current and future generations of smart grid protection equipment.”

The AIC CoilMaster from C&F Quadrant incorporates a unique coil firetube heat exchanger which condenses in both heating and DHW mode to deliver performances of up to 104% in DHW production and 108% in heating mode. It can be used as a combination boiler providing heating and DHW from a single unit. It is the perfect choice where space is at a premium and is also ideal as a replacement for older units, with an accessible top flue spigot.

Twin condensing When condensing in heating mode, the return from the heating circuit enters the lower part of the primary, activating the condense mode. Then the internal pump speeds up the circulation of the primary water around the heat exchanger flue tubes, increasing the counter current exchange and consequently the thermal efficiency of the boiler.

When condensing in DHW mode the cold feed enters the lower part of the DHW stainless steel coil and, thanks to the low temperature of the bottom of the primary circuit, the boiler is in constant condensation of the flue gases which ensures a continuous delivery of hightemperature DHW at the top outlet.

Once up to temperature, the CoilMaster simultaneously produces heating and DHW in condensing mode.

Building Services Engineering I January/February 2025 39

Unique coil firetube The coil firetube heat exchanger within the Coilmaster is constructed from the highest-grade stainless steel, including the welded internal circuit pipework and a welded condense dish.

The firetube design has a unique geometry of tubes that increases the heat transfer by creating a turbulent flow of the gases. These high-quality stainless steel components maximise the boiler’s efficiency and reliability, which in turn adds to the longevity of the boiler.

Exceptional output CoilMaster offers exceptional output from a compact unit and can satisfy high heating and DHW requirements without the need to install additional storage. It delivers the advantages of condensing technology in both heating and DHW modes, providing high volumes of efficient instantaneous DHW. It also minimises the risk of fouling, thanks to the indirect heat exchanger, while the risk of legionella is eliminated.

IBSE Technical Director Dr Anastasia Mylona represented CIBSE at COP29 in Baku, Azerbaijan, where she contributed to global climate change and sustainability conversations. Dr Mylona was invited to speak at the ‘Sustainable Cooling in a Warming World,’ event hosted by the UK Government’s Department for Energy Security and Net Zero in the Blue Zone UK Pavilion, where she highlighted the urgent challenges facing the building industry in its race to achieve net-zero and decarbonisation targets.

In her speech, Dr Mylona emphasised that while the building industry has made strides towards decarbonisation, it must also adapt to the climate impacts already occurring and those we anticipate in the future. She pointed out that even if net-zero emissions were achieved immediately, the climate would continue to change for several decades, with rising temperatures and an increase in extreme weather events.

One of the major challenges for the building industry, Dr Mylona noted, is how to meet the growing demand for cooling in the coming

Wilo water quality systems

‘Sustainable Focus’ The treatment of water in closed heating and cooling systems is crucial for avoiding harmful microbiological fouling, corrosion and scale in the system. These result in unpleasant sounds in pipes and radiators, but also cause energy waste, poor system performance and reliability. It inevitably leads to early replacement of the plant and the components. Therefore, water quality/ efficiency is a central topic in building services.

Wilo water quality systems deliver a constant pressurisation, de-aeration and topping up in sealed heating installations (acc. to EN 12828) and chilled water (cooling) installations.

They use innovative and proven technology – such as coalescence and flow velocity reduction – to remove air and solid particles from the water.

Whether a domestic application or commercial installation with large heating or cooling systems, the Wilo series of pressure-maintaining systems, degassing automats, air and dirt separators and automatic air vents provide the most efficient solution.

Wilo Sinum, ideal for pressurisation, de-aeration and topping up in sealed heating installations.

Wilo-Sinum “fill and spill’’ Wilo-Sinum is the ideal solution for pressurisation, de-aeration and topping up in sealed heating installations where standard diaphragm expansion equipment is limited.

The system offers continuous degassing using three selectable operation modes and, thanks to the digital and analogue inputs, it can be optimally integrated into an existing building management system. The large series of closed

vessel sizes allows adaptation for a wide number of applications across all market segments.

Key benefits • Easy installation thanks to intuitive menu navigation, large display and self-learning microprocessor; • Different operating modes guarantee continuous degassing; • Advanced technology ensures low power consumption, long service life and easy maintenance; • High convenience through volumetric controls and automatic topping-up during the heating and cooling cycles; • Modular design for a high level of installation flexibility; • Optional: Integration in to existing building management systems through digital and analogue outputs.

Digital CPD Training Wilo Ireland is currently undertaking an extensive digital CPD programme on these topics that is proving extremely popular and generating a great deal of interactive discussion.

It is freely available to all consulting engineers, contractors and end-users.

“It is encouraging to see the marketplace in Ireland so aware of, and embracing, the importance of system efficiency”, says Michael O’Herlihy, Wilo Ireland. “The elimination of air and solids in heating systems ensures maximum operation efficiency and energy transfer/usage. It is also in line with Wilo’s sustainability commitments and its selection as one of the 50 Sustainability & Climate Leaders in the world.

“This trend towards heating system efficiency will contribute greatly to reducing Ireland’s energy use and carbon emissions, and the role of high-efficiency, digital pumping equipment is a critical element in the success of this initiative.”

A new US administration:

What now for Europe's competitiveness?

With the new US administration’s agenda being rolled out, Sue Arundale, Director General of the European Federation of Engineering Consultancy Associations (EFCA), examines what impact this might have on Europe’s agenda over the next four years.

F

ollowing the changes in the US administration in January, EFCA has been following the plethora of early policy announcements in an attempt to make an initial analysis of the consequences for our sector in Europe. The withdrawal from the Paris Agreement, the planned investment in frontier technologies and the threat of tariffs are just some of the developments that look set to pose challenges for consulting engineering firms headquartered in the EU. We look at the headlines from their perspective and consider some of the big questions that need to be answered so that these firms are better prepared to navigate the new business environment.

What now for the UN climate targets?

How do we continue our efforts to reach our climate goals in the face of the clear prioritisation of fossil fuels in the US? Emissions do not stop at borders, and the climate emergency needs a global response. The European Union has taken a strong lead, introducing regulation, certification, linking

funding to clear green criteria and bringing an eventual end to the use of the worst offending sources of power as well as non-compliant products and industrial processes.

Industry and other businesses have duly followed, overhauling their unsustainable practices and turning the threat of inevitable and ongoing climate catastrophe into business opportunities.

So, how will our leaders ensure that these efforts have not been in vain and keep Europe on track while also guaranteeing the economic viability of maintaining the current sustainability requirements?

This will surely be one of the most urgent talking points in the institutions.

Another related question is how to keep our biggest industries and the respective ecosystems from bailing out and simply relocating to the US. Although a mass exodus seems unlikely at this stage, the EU must address the lagging competitiveness of the bloc. This was already biting and threatening future prosperity, and EFCA already called for measures to improve Europe's autonomy in its manifesto for last year's EU elections1.

Building Services Engineering I January/February 2025 47

“Emissions do not stop at borders, and the climate emergency needs a global response”

What now for Europe's Big-Tech?

Speaking of autonomy, this is frequently on the agenda of EFCA's Digitalisation and BIM, and Future Trends committees. The storage of data in clouds, the jurisdiction under which the biggest technology firms operate, the lack of adequate infrastructure to facilitate the rapid expansion of frontier technologies as well as a shortage of qualified engineers, especially those with expertise in the most innovative methods… the list of challenges is already long.

Add to that the massive investment in AI promised in the US, along with a favourable environment for innovation and a different attitude to risk, and we see that the digital transition in Europe just became more complicated. This at a time when we have recently seen a spurt of measures intended to offer a regulatory framework that

is fit for the digital age.

How will all of this be tackled?

EFCA will continue to push for a secure method of sharing data, fair and transparent rules that prevent the loss of control of the design process and the interoperability of systems and software, as well as open standards. Nevertheless, it rather looks as though these things alone will not be enough to match the ambitions of the US, which was, after all, already the world leader in this field.

Is there any good news?

Well, before the gloom sets in, we have to see how the ambitious American growth agenda will be implemented.

Furthermore, it actually seems that this wake-up call is timely, given that the European commissioners are now in post with an ambitious agenda of their own. For too long, we have been dragging our feet, seemingly unable to meet our own aspirations and even the

corresponding targets aimed at both reviving the economy while at the same time protecting our citizens and our environment.

Perhaps the extent of the US administration's intentions, as well as the undercurrent of national optimism there will provoke urgent and essential reflection about how to react. The EU is very different to the US. As a bloc, with all the democratic processes essential to finding compromises for 27 countries (as opposed to 50 states), it is not operating in like-for-like circumstances. However, with some intelligent and pragmatic vision and leadership, the EU-27 could take stock of where we are and approach this time as an opportunity for change, the aim of which will be to ensure we can continue to compete on the world stage.

The same goes for consulting engineering firms. Although too early to be specific, and as we, in any case, are still waiting for the European Commission Work Programme 2025, EFCA will continue to serve consulting engineering firms, offering support and representation in the policy-making process. The federation has good relations with both the International Federation of Consulting Engineers (FIDIC) and its US member association, the American Council of Engineering Companies (ACEC), and is active via these and the other FIDIC members in measures and joint actions that promote the sector at a global level.

With that in mind, EFCA is confident that our sector will not only survive, but will adapt, continue to innovate and find new opportunities from this unpredictable period.

The SmartConnect feature transforms the Healthbox Hygro into a smart home ventilation system, featuring a dedicated appbased dashboard that provides essential, real-time information on humidity and indoor air quality, ensuring an easy-to-understand visual representation of the healthy environment for residents.

Installers benefit from the Healthbox Hygro’s minimalistic design (20cm x 39cm without valves), which is small enough for horizontal or vertical installation in constrained spaces. The revamped sensor valves, directly attached to the unit, reduce room noise and eliminate the need for extra wiring, with up to seven valves connecting seamlessly via a network cable.

In another significant development, a specially designed roof vent, suitable for use with tiles and slates, plays a pivotal role in ensuring the Healthbox Hygro

operates at its full ventilation capacity of 430m3/hr while also reducing resistance in the ductwork.

Notably, this particular design innovation effectively directs airflow above the roof surface, safeguarding against staining over time.

Installation app The Healthbox Hygro’s dedicated installer app enables quick and precise air flow rate adjustments at each of the extraction points.

The unit then self-calibrates and self-commissions, and generates a report after the process is completed. This offers data on the ducting system pressure drop, allowing quick confirmation of a correct functioning, demandcontrolled extraction system.

The installer app also grants access to a web portal where all installations are visible, complemented by real-time status information, if the units are connected to the internet.

Homeowner app The homeowner app offers realtime room-by-room air quality monitoring, enabling users to adjust ventilation levels and select operation profiles: “health,” “intense,” or “eco.” By default, the “health” profile is active, striking a balance between energy efficiency and air quality. The “intense” profile is ideal for sensitive areas such as a baby’s room.

All you need to know about SF6 Gas Regulations 2015/2066 – 2024/573 David Roome outlines key regulations engineers must adhere to when using or engaging persons to work with SF6 - F Gas, which has a global warming potential of 22,800 times that of carbon dioxide.

F

irst, what is the purpose of the regulations? To reduce global warming.

A company or person that handles Fluorinated Greenhouse Gas (SF6 – F-Gas) must comply with the statutory requirements.

Why do we need F Gas regulations, and why do companies/engineers need to be registered?

SF6 - F Gas is one of the most damaging to the atmosphere and is responsible for changing the world’s climate.

All engineers handling F Gases must possess a personal certificate for the type of system they are going to be working on.

Therefore, when employing a company or engineer to work on equipment containing SF6 - F Gas, you must check the company’s and the individual engineer’s certificates before placing an order.

For a company to register and obtain an F-Gas certificate, it must provide evidence that all engineers employed who handle SF6 -F-Gas are competent to carry out their work.

Understanding SF6 Gas: Its applications, impact and handling requirements Sulphur hexafluoride (SF6) might not be a household name, but within the realm of building services and electrical systems, its role is

paramount.

This article introduces SF6, delving into its uses, environmental impact and the stringent handling requirements it demands.

So, what is SF6 Gas? SF6 is a manufactured gas that appears as a colourless, nonflammable and innocuous substance under normal atmospheric conditions. It is one of the most stable gaseous chemicals known, with a molecular structure of one sulphur atom bonded to six fluorine atoms. At five times the density of air, SF6 possesses remarkable properties, including superior electric insulation and arc-quenching capabilities. These qualities make it indispensable in electrical power systems and certain medical applications, such as LINAC waveguides used in radiotherapy, MRI machines, production of magnesium and particle accelerators, and it is widely used in semiconductor manufacturing processes as a highly efficient etching and cleaning agent.

SF6 Gas in electrical applications SF6’s exceptional properties make it a cornerstone in electrical distribution and transmission systems. Its high chemical stability and excellent dielectric strength -approximately 2.5 times greater than air - enable it to

David Roome.

function as a reliable insulation medium. Moreover, SF6 is highly electronegative, allowing it to efficiently absorb free electrons, which plays a critical role in preventing electrical arc formation.

How SF6 works in electrical systems Electrical arcs are intense discharges of light and heat caused by ionised air or conductive channels in systems like switchgear. SF6’s ability to absorb electron energy lowers arc temperatures and disrupts the electron avalanche effect that leads to flashovers. Even when subjected to electrical discharges, SF6 exhibits a “self-healing” property; its atoms recombine, restoring its insulating capacity. This characteristic and its thermal conductivity make SF6 a preferred choice in systems requiring exceptional reliability.

Typical applications of SF6 in the power industry F Gas - SF6 is widely used in: 1) Medium and high-voltage switchgear, including ring main units and gas-insulated switchgear (GIS) 2) Wind and solar farms, ensuring operational stability 3) Substations and power

Building Services Engineering I January/February 2025 61

The environmental impact of F Gas - SF6 While SF6 is an engineering marvel, it carries a significant environmental burden. With a global warming potential (GWP) of 22,800 times that of CO2, SF6 is the most potent greenhouse gas still in active use. Its GWP means that even small quantities of SF6 can have a significant impact on climate change, and its atmospheric lifetime exceeds 1,000 years, making it a long-term environmental concern.

F Gas Regulations and GWP Metrics In 2015, the classification of “F Gas” (fluorinated gases) was updated under European regulations to categorise gases based on their GWP. This framework allows for a direct comparison of greenhouse gases with CO2 assigned as a baseline GWP of 1. SF6’s staggering GWP underscores the necessity of careful regulation and handling to mitigate its environmental footprint.

Could there be future alternatives?

Although efforts are underway to develop less harmful alternatives, SF6 remains essential in many applications due to the challenges of replicating its unique properties.

It is anticipated that SF6 will remain in widespread use for another 20 to 30 years, provided strict adherence to F Gas regulations is maintained.

Specialist handling of SF6 Given its environmental impact and chemical properties, handling SF6 requires specialised knowledge, tools and adherence to stringent protocols.

Key requirements for SF6 handling 1. Regulatory compliance: SF6

is categorised under F Gas regulations, necessitating specific training and certification for personnel involved in its handling.

2. Dedicated equipment: SF6 systems utilise unique connections and require selfsealing hoses, typically with DN8 fittings, to prevent leaks. General refrigerant handling tools are unsuitable for SF6.

3. Gas recovery and analysis: Recovery equipment must extract SF6 to pressures as low as five millibars to ensure minimal environmental release. Also, specialised analysers are essential to assess the gas condition during recovery or installation.

4. Disposal of degraded gas: When decomposed, SF6 can generate harmful by-products, such as sulphur dioxide, posing risks to both health and the environment. Recovered gas must be disposed of via certified facilities to mitigate these hazards.

SF6 handling experts: Meeting the challenge With over 30 years of experience, SF6 Recovery Ltd. specialises in the safe management of SF6, bridging the gap between regulatory compliance and operational efficiency. Initially established in response to the Kyoto Protocol’s introduction of F Gas regulations, the company now offers tailored services for power distribution and medical sectors.

In Conclusion: Balancing utility and responsibility SF6’s unparalleled properties make it indispensable in critical industries, but its environmental impact cannot be overlooked. By understanding its uses, acknowledging its risks and committing to responsible handling, the building services sector can strike a balance between leveraging

its benefits and minimising its footprint. With evolving regulations and ongoing innovation, the industry stands at a pivotal moment to ensure that SF6 is managed safely and sustainably for years to come.

The integration of heat pumps into existing buildings – Author: Sean McMahon

H

eat pumps are becoming a vital solution for sustainable building services design, especially as the industry transitions toward decarbonisation and the use of low-carbon technologies.

My report, ‘The Integration of Heat Pumps into Existing Buildings’, explores the challenges and

opportunities of retrofitting heat pumps into non-domestic buildings, using best practices such as those outlined in CIBSE AM17.

Design challenges and considerations Integrating heat pumps into existing buildings requires addressing

challenges such as legacy systems, fluctuating demands, and space constraints. Key considerations include: • Occupant comfort: Ensuring consistent heating, cooling, and DHW across diverse zones while optimising energy efficiency.

A “Fabric First” approach was employed to improve the thermal envelope, reducing heat loss and lowering overall energy demand, enhancing system performance.

• Energy efficiency: Reducing demand through advanced sequencing and part-load controllers.

• Safety and reliability: Adopting low-GWP refrigerants like R290

“By leveraging advanced technology and adhering to industry standards, these systems are pivotal to advance sustainable building services design.” while complying with safety and the F-Gas regulations.

Case Study: Burlington Road, Dublin The report features a case study on a commercial office building at Burlington Road, Dublin, which underwent a complete retrofit.

This included replacing all emitters and pipework, allowing the use of low-temperature fan coils for space heating and cooling.

The original system, which utilised gas boilers for heating and DHW and chillers for cooling, was replaced with a multiple heat pump setup: • Two multi-functional fourpipe heat pumps to provide simultaneous heating and cooling, utilising polyvalent heat pump technology.

• One air-source heat pump to provide the additional heating capacity and act as redundancy in the system.

with polyvalent heat pumps and sequencing controls.

• BE GREEN: Advanced controls, such as weather compensation, are integrated into the system to help further improve the operational energy.• BE SEEN: Performance monitoring to ensure operational targets are met.

Sean McMahon, Author, The Integration of Heat Pumps into Existing Buildings report.

• One water-to-water heat pump, dedicated solely to DHW production, uses the low-grade heat from the four-pipe units as a water source.

• Thermal buffer tanks, ensuring efficient load management for heating, cooling, and DHW. The buffer tanks also improve the reliability of the heat pumps by preventing short cycling of the compressors since the minimum required water content is achieved.

The system operates with 45/40°C flow and return temperatures for the space heating and acts as a water source for the water source heat pump, 6/12°C for space cooling, and a 60°C outlet temperature for DHW. The system met a heating demand of 1000 kW, a cooling load of 1400 kW, and a DHW requirement of 105 kW. Sustainability and Futureproofing The project adhered to the ‘BE LEAN, BE CLEAN, BE GREEN, BE SEEN’ energy hierarchy: • BE LEAN: Demand reduction through improved thermal performance and reduced heating and cooling loads.

• BE CLEAN: Efficient energy use

Benefits for the building owner/ occupier The integration of heat pumps offers numerous advantages: • Energy efficiency: Heat recovery and low-temperature operation reduce energy consumption and operating costs.

• Decarbonisation: Moving away from fossil fuels aligns with evolving sustainability regulations and CSRD reporting requirements.

• Economic value: Green-certified buildings attract premium tenants and increase asset value.

In conclusion This report demonstrates how heat pumps, combined with advanced design strategies, can transform existing buildings into low-carbon, energy-efficient assets.

By leveraging advanced technology and adhering to industry standards, these systems are pivotal to advance sustainable building services design.
