Resilience yields results

Despite the obvious challenges of the moment – skills shortages, rising costs, marketplace uncertainty and still some supply/logistics issues –construction in general, and building services engineering in particular, is showing tremendous resilience.

While there has been a decline in civil engineering in particular, and equally so in housing, commercial continues to buck this trend. Consequently, the vast majority of companies – consultants, contractors and product suppliers – are actively trying to recruit personnel.

Immediate and short-term challenges will still continue to impact and, in turn, cause some marketplace unease. However, most commentators agree that the overall outlook is positive with construction output still set to hit nearly €25 billion for 2023. As we head in to the Summer months, that’s certainly reason to be cheerful!


Weir elected new Chair

Stephen Weir, newly-elected Chair of CIBSE Ireland, emphasises the importance of digital construction, how critical data analytics are in relation to building systems, and the urgent need for a human centric approach to building and engineering services design.

Pinegy discount on solar installations

Pinergy SolarElectric is already giving residential customers the benefit of the VAT reduction that is expected to be formally removed from domestic and public building installations in early July as part of the Spring Finance Bill.

This planned move by the Government should see the cost of installing solar panels reduced by as much as €1,000, based on the cost of an average installation falling from €9,000 to €8,000

However, the 13.5% discount offered on domestic solar energy installations will be subject to a successful site survey, which is a free and “no obligation” service from Pinergy SolarElectric.

Digitalisation the key

Paul McCormack, Programme Manager for the Belfast Metropolitan led EU project ARISE (pictured), recently presented an address to a key European upskilling audience in Brussels to help mark the European Year of Skills, 2023.

The Architects Council of Europe (ACE), and the European Association for Architectural Education, co-organised the one-day conference which also included an address from the President of the European Association for Architectural Education, Oya Atalay Franck. This public conference – titled New European Bauhaus-Upskilling (Education and Practice) – was web streamed live from the ACE website. The day showed how architectural research and education can activate ecosystems that address the challenge of climate change.

The Belfast Metropolitan led EU project has nine European partners and encourages a new hybrid way of learning while creating a digital mobile curriculum that supports upskilling on energy efficient buildings and BIM.

Among other things, Paul McCormack said: “As we strive to reduce the carbon footprint of the built environment, we must use the advantages of digitalisation to accelerate the upskilling and retraining of the existing workforce, and to deliver a huge wave of digitally-informed and empowered training for the new workers entering the workforce.”

‘We must support wind energy ports’

With the publication of a new report called We can build them: Supporting Irish ports to build offshore wind farms, Wind Energy Ireland has again called on the Government to invest in Ireland’s ports to give industry the best chance of achieving the Climate Action Plan targets at the lowest cost to consumers.

The report includes an examination of how port infrastructure for offshore wind energy is funded elsewhere, both within and outside the European Union, and highlights the important role of state support in giving confidence to investors.

The report builds on the 2022 National Ports Study, which showed that Belfast is the only port on the island of Ireland that is currently fully equipped to serve as a construction base for offshore wind farms.

Several ports, like Rosslare, Cork Dockyard and Shannon-Foynes, have plans to expand their port infrastructure so they can be used to build offshore wind farms, but these improvements require significant amounts of investment. While the ports can, and will, raise much of this themselves, support from the state is crucial to de-risking initial investment.

‘Powerful’ winds

Ireland’s wind farms set a new record this year with their best ever performance for the month of April. Wind energy provided 35% of the country’s electricity last month and, for the first four months of the year, has met 38% of power demand.

However, Wind Energy Ireland says that the current planning system relating to wind project approvals is not fit for purpose and is considerably hampering further progress.

New President for ACEI 2023-2024

Kavanagh fully committed to ACEI Sustainability Vision

James Kavanagh was recently elected President of the Association of Consulting Engineers of Ireland (ACEI) for the 2023-2024 term. James is the CEO of Varming Consulting Engineers, a building services engineer and a 1990 graduate from DIT Bolton Street College of Technology, DIT (now the Technological University Dublin). His first active involvement in ACEI was as a member of the Mechanical & Electrical (M&E) subcommittee and, since then, he has served on the Executive Board as ordinary member, Honorary Treasurer and Vice-President.

Established in 1938, ACEI is a voluntary, selfregulatory, professional body representing the business and professional interests of firms and individuals engaged in consulting engineering on the island of Ireland. Currently there are 105 ACEI member firms of all sizes – micro, SMEs and multinationals – with offices all over the country employing more than 4600 people.

As the voice of the consulting engineering profession, the Association assists in resolving issues of importance for consultants and their clients, and contributes to the development of relevant public policy through participation in industry fora and Government committees. Its nine sub-committees work very hard to support members, including the development of model conditions of engagement and policy papers.

ACEI provides a suite of important services to members, including CPD, communications and awards. Among other categories,

ACEI will continue implementing key initiatives already underway, including its client and stakeholder engagement programme.

James Kavanagh, the newly-elected President of the Association of Consulting Engineers of Ireland (ACEI).
10 Building Services Engineering l May/June 2023

two of the annual Engineering Excellence Project Awards focus on sustainability, in both the natural and built environments. The Association also has a key role in lobbying local, national and European politicians on important issues for the sector. These cover everything from progressing the National Development Plan (NDP) through to strategic planning, Government contracts, Professional Indemnity Insurance (PII) and construction health and safety.

During James’s term of office, in conjunction with the Executive members, Secretariat staff and sub-committees, ACEI will continue implementing key initiatives already underway, including its client and stakeholder engagement programme. This initiative successfully highlights the value member-firms bring to projects, focusing on design for performance. It also helps to identify the importance of introducing innovative and sustainable modern methods of construction (MMC) to the sector, addresses the integral role consultants play in the delivery of the NDP, and

outlines the sustainability and other challenges member firms are facing.

A fully-mobilised construction sector is essential to the delivery of important housing, infrastructure and other projects central to the country’s further development. It is also crucial to consider making a change, from a transactional-type construction approach towards one based on partnership, quality, whole-life costs and sustainability.

In this context, ACEI has advocated in lobbying Government that the NDP should prioritise the delivery of projects that make us more resilient as a society, better transitions us to a sustainable low-carbon community, and enable the development of renewables that are critical to addressing climate action.

The Association has also suggested that a senior Government appointment should be made in relation to

responsibility for retrofit initiatives, reporting directly to the Minister for the Environment, Climate and Communications, to provide leadership in this area, particularly in relation to the 500,000 homes needing renovations.

The continuing provision of energy in the existing environmental climate is also a key concern to ACEI. Its recommendations to Government to address the situation using renewables include:

• Develop a solar energy strategy;

• Strengthen policy framework to incentivise electricity storage and interconnection;

• Promote research and development in “green” hydrogen;

• Develop a long-term plan to take advantage of a potential of at least 30GW of offshore floating wind power in the Atlantic.

Building Services Engineering l May/June 2023 11

In 2021, ACEI’s active Sustainability Committee developed the ACEI Sustainability Vision, which looks to a future “shaped by socially and environmentally responsible design, where true long-term costs and benefits are considered across entire project lifecycles.” In effect, this aspiration addresses the important requirement to move from a linear to a circular economy.

The vision statement also notes that ACEI “will continue to help shape policy and to influence consulting engineering firms and their clients to pursue wellconceived projects for the benefit of communities and the environment. Such projects will be planned and designed to go beyond the traditional focus on function, cost minimisation and programme, to also address resilience, long-term sustainability and societal impacts.”

Within the vision, the ACEI commitment to climate action is a recognition of “the existential crises that humankind faces resulting from climate change; the significant influence that consulting engineers have on the built environment of the future; the potential for client decisions to contribute positively to future climate outcomes; and the crucial nature of the sustainability advice that member firms provide to clients.”

Building on the Sustainability Vision, one of the most important current ACEI activities is the Association’s leadership in the built environment sector in relation to acting on climate change. In 2022, ACEI made a firm commitment to the international Pledge to Net Zero (PtNZ) programme and partnered with the UK-based PtNZ campaign. PtNZ is led by a steering committee that includes the Society for the Environment (SocEnv), the Institute of Environmental

Management and Assessment (IEMA), the Association for Consultancy and Engineering (ACE), and the Environmental Industries Commission (EIC). Leading environmental consultancies WSP and AECOM are also part of the initiative.

The ACEI PtNZ commitment has been made to provide ACEI member firms with a science-based greenhouse gas (GHG) emissions reduction programme, which comes with support and guidance as well as the sharing of good practice. More than 165 organisations worldwide have signed up to the pledge so far, with all signatories committing to:

• Setting, and committing to deliver, a greenhouse gas target in line with either a 1.5°C or well below 2°C climate change scenario covering buildings and travel as a minimum;

• Publicly report greenhouse gas emissions and progress against this target annually;

• Publish one piece of research or thought-leadership piece annually on practical steps to deliver a net zero greenhouse gas economy.

Alternatively, signatories may choose to provide mentoring and support for smaller signatory companies in setting targets, reporting and meeting the requirements of the pledge. ACEI continues to advocate for climate action and members are at the forefront of designing innovative energy solutions to help reduce carbon emissions from homes and from the environment. By registering for the PtNZ commitment, ACEI consulting engineering practices demonstrate their actions as leaders in the field by making a real difference within their own operations, and by working in an integrated way to continue providing world-class advice on sustainability and environmental concerns to clients. ACEI members are committed to helping deliver greenhouse gas targets in line with necessary climate change scenarios, covering buildings and travel as a minimum.

As President, James Kavanagh plans to continue the leadership on the ACEI Strategy 2022-2025 to support a vibrant consulting engineering community. In this context the strategy’s vision outlines “a future shaped by social and environmentallyresponsible design.” It continues with a mission “to support a vibrant consulting engineering community, within which member firms can grow successful businesses that deliver sustainable engineering solutions for the benefit of humankind.”

James also aims to uphold and maintain the high standards set by the ACEI to date, and looks forward to building on the work already undertaken by the Association. Key to this objective will be delivering value to ACEI members, while fostering and enhancing their standing in the consulting engineering profession and Irish built environment sector.

Stephen Weir elected CIBSE Ireland Chairperson

Stephen Weir, the newlyelected CIBSE Ireland Chairperson, joined the CIBSE Committee in 2017 and has previously served as Honorary Secretary and then Vice Chair. In addressing the recent AGM, he paid particular tribute to outgoing Chair Michael Curran who, he said, had served in the role with great distinction, despite the exceptional circumstances presented by Covid-19.

He also acknowledged the contribution of the other CIBSE Ireland officers and committee members, and commended them for the expansive programme of technical and social events delivered under Michael’s tenure.

In looking to the future, he said: “I would like to thank the incoming committee for coming on board and look forward to working with them over my tenure as

Chairperson. Particular thanks to Laura McMahon, my Vice-Chair.

“The committee is in an extremely strong position with a vast array of knowledge and technical excellence across energy management, consultancy, education, contracting, design and supply.

“My vision for my tenure as Chairperson is that of continued collaboration across industry, from consultants to contractors and suppliers alike. This, along with industry development for routes to chartership, is a key priority. While not losing sight of the fundamentals and importance of a chartered engineer from design to installation, it is equally important that we explain to others the benefits of actually being chartered.

“Having worked in the industry for over 20 years, from apprentice to director level, I am keen to develop long-term career paths for trades and engineers alike, with a drive on inclusivity and diversification for all. With the construction industry in a resource shortage, we need to get across the importance of building services and the role of mechanical and electrical engineers. Personally, coming from an electrical background, I wish to engage further with electrical engineers and contractors, as their

CIBSE membership and chartership should be seen as a key metric for their career development.

“The role of the engineer is key across not just MEP but also for main contractors, specialist sub-contractors and suppliers. We need to promote the benefits of becoming a CIBSE member, and of getting chartered, where applicable. Support for all is the theme.

“We are truly in the age of digital construction. Data analytics of building systems and how best to optimise these post-occupancy for the wellbeing of the user around a human centric approach to design are critical. CIBSE is fully committed to education around this topic and is already involved in the development and standardisation through its intelligent buildings group. It is currently working on the assessment of the whole-life value of intelligent buildings, and on strategy development for healthy and sustainable buildings with outcomes, rather than technologies, to be defined.

“In conclusion, I am truly honoured to be CIBSE Ireland Chairperson as we embark on a new phase of development and I am committed to representing our members in a positive and productive manner throughout my tenure.”

Keltech IoE DDN or Dual Distributed Network is a fault managed power solution (FMPS) that delivers low voltage (LV) direct current (DC) microgrids and a fibre backbone in a single cable system for use in intelligent sustainable buildings.

The construction industry has long been associated with a high level of energy consumption and significant environmental impact. Buildings, both residential and commercial, account for approximately 40% of global energy consumption and around one-third of greenhouse gas emissions. As global awareness of the need for sustainable development continues to grow, the construction industry is facing mounting pressure to address these challenges and make a transition towards NetZero carbon emissions.

In response to these sustainability challenges, the construction industry has been gradually embracing green building practices, materials and technologies. This includes adopting energy-efficient designs, using environmentally-friendly construction materials, while also implementing renewable energy solutions such as

in the

solar panels and wind turbines. Furthermore, green building certifications like LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method) have become increasingly popular, providing guidelines and benchmarks for sustainable construction practices.

One cutting-edge technology that holds great promise for revolutionising the building industry and significantly contributing to the NetZero goal is the use of DDN. This comprehensive article provides an overview of the benefits of DDN, and then illustrates how it can enhance energy efficiency by supporting various applications that inherently require DC power to operate.

DDN offers several advantages that makes it an ideal choice for intelligent sustainable buildings. DDN utilises Voltserver’s Digital

electricity (DE) to create a human safe low voltage power distribution headend. Included are: Energy efficiency – DC power distribution is more energy-efficient compared to AC (alternating current) power distribution. Studies have shown that energy losses from AC to DC conversions can range from 5% to 20%, depending on the specific devices and applications. However, by using DDN, buildings

can minimise the number of AC to DC conversions, thus reducing energy waste and improving overall efficiency. For instance, a study conducted by the National Renewable Energy Laboratory (NREL) found that using DC microgrids in commercial buildings can result in energy savings of up to 14%; Reduced cabling – The use of DDN leads to a significant reduction in cabling requirements. Since DDN requires fewer and smaller cables compared to traditional AC power distribution systems, the use of steel wirre armoured (SWA) cabling can be decreased by up to 30%. This leads to lower material and installation costs, as well as a decreased environmental footprint; Enhanced safety – DDN operates at lower voltages, which almost removes any risk of electric shock and fire hazards associated with higher voltage AC systems; Integration with renewable energy sources – DDN can be easily integrated with renewable energy sources like solar panels and batteries, making it simpler for intelligent sustainable buildings to generate and store clean energy.

Now that the advantages of DDN have been established, let’s explore how they can support various applications in intelligent sustainable buildings, leading to better energy efficiency over the lifespan of the building:

LED lighting – LED (light emitting diode) technology consumes up to 85% less energy compared to traditional incandescent bulbs and has a longer lifespan. Since LED lights require DC power to operate, they can be directly connected to the DDN, minimising energy losses from AC to DC conversions and further enhancing energy efficiency;

Access control systems –Modern access control systems, including card readers, biometric scanners and electronic locks, require DC power to function. By integrating these systems with DDN, intelligent sustainable buildings can optimise their energy consumption and reduce the need for AC to DC conversions;

Laptops and phones – Most portable electronic devices, such as laptops and smartphones, use DC

power for charging and operation. By adopting USB-C charging infrastructure powered by DDN, intelligent sustainable buildings can reduce electronic waste and energy consumption by eliminating the need for multiple charging adapters and cables; HVAC (heating, ventilation and air conditioning) – Smart HVAC systems in intelligent sustainable buildings leverage IoT (Internet of Things) devices and sensors to monitor and control indoor temperature, humidity and air quality. Although these systems typically use a mix of AC and DC power, they can benefit from the energy-efficient nature of DDN, reducing energy losses from conversions and optimising energy consumption based on real-time data, occupancy and weather conditions.

Several successful examples of sustainable construction projects incorporating FMPS power delivery design are starting to emerge. The Edge, a NetZero office building in Amsterdam, is a notable case study.

This building utilises a combination of solar panels, smart lighting and fault-managed power to achieve outstanding energy efficiency, making it one of the most sustainable buildings in the world.

Another example is the Bullitt Centre in Seattle, which is considered one of the greenest commercial buildings in the United States. The building incorporates a FMPS, solar panels and other energy-efficient technologies to achieve a high level of self-sufficiency and minimise its environmental footprint.

In conclusion, by leveraging the benefits of DDN and its compatibility with various applications that inherently require DC power, intelligent sustainable buildings can significantly improve their energy efficiency while reducing their environmental impact. As the construction industry continues to evolve and embrace sustainable technologies, DDN offers a promising solution for creating a cleaner and more energy-efficient built environment, contributing significantly to the global pursuit of NetZero carbon emissions.

LEDVANCE solutions at King’s Cross Station

New high bay DALI luminaires from LEDVANCE

LEDVANCE LED lighting solutions have been installed across platforms 1 to 8 at London’s historic Kings Cross Station in a move that will significantly reduce maintenance costs and energy consumption, while future-proofing the building’s illumination systems.

The recently-completed retrofit saw numerous traditional 400W metal halide lamps replaced with LEDVANCE high bay DALI 115W 4000k luminaires with IP65 protection, fitted with high-quality aluminium reflectors.

The Victorian building is considered to be a site of national significance and even small changes to its structure require planning authority approval. While looking the same as the old lights and providing the same amount of brightness – both essential requirements – the new LEDVANCE units use much less electricity and last far

longer, providing a constant luminous flux across their five-year guaranteed lifespan. Thanks to their DALI-2 certification, they can also be used with any lighting-control system that may be installed in the future at the station.

“The old lamps were failing frequently and changing them required specialist lift equipment which, for health and safety reasons, could only be used at certain times of the night when the concourse was empty,” said Stevie Young, Sales & Projects Manager, LEDVANCE Ireland. “The station needed new luminaires that

were far more reliable and energy efficient, but to keep in line with the original appearance of the building they had to look the same as the old lamps.”

LEDVANCE provided full support throughout the nine-month project, including a detailed lighting design, full technical advice and ongoing aftercare. “We visited the site numerous times to discuss what we were offering and provided samples of the product for approval,” continues Stevie. “We’ve even supplied voltage meters so the customer can carry out tests on site in case of any issue. This was a very successful installation, and everyone is really pleased with the results.”

In total over 160 high bay DALI 155W, 4000K LEDs and reflectors have been installed across eight platforms at the station, providing energy savings of up to 60% compared to conventional high bay luminaires. LEDVANCE high bay solutions are an ideal replacement for luminaires with mercury vapour or metal halide lamps as they offer the flexibility of being dimmable and can switch on and off instantly. This also allows savings to be realised through daylight and occupancydependent operation.

This benefit is also ideal for warehouses, logistics halls and many other industrial applications, including high ceiling environments such as shopping malls, airports, transport stations and commercial buildings. In addition to the much lower energy consumption, LEDVANCE high bay LEDs need replacing less frequently and this too leads to maintenance cost savings.

LEDVANCE lighting solutions come in environment-friendly cardboard packaging with all relevant product information immediately visible on the outside of the box.

Condair celebrates 75th anniversary

Humidity control specialist, Condair, is celebrating its 75-year anniversary. Having been founded in 1948 as Defensor AG in Switzerland by chemist, Dr Bernard Joos, the company is marking the occasion across its many offices around the world.

Damien Power, Area Sales Manager for Condair in Ireland, commented: “75 years is a wonderful milestone to achieve as an organisation. Condair’s longevity is testament to its ability to innovate and develop marketleading technology, and to deliver it with expert knowledge and service support. The company has continually operated at the forefront of the humidification sector and continues to lead the field in engineering excellence.”

The first product offered back in 1948 was an air spray disinfection system, which “defended” against cattle infections, hence the company name at the time of Defensor. It soon became apparent that the humidification properties of the atomiser were greatly beneficial in several manufacturing sectors, particularly cheese ripening rooms.

Through the 1950s and 1960s, Defensor continued to develop humidification technologies. Spray and evaporative humidifiers were introduced, along with the invention of the electrode boiler steam humidifier and the pioneering use of resistive element heaters to boil water and humidify the air.

In 1975 Walter Meier, a Swiss importing business, acquired Defensor. In 1981 it

also acquired Plascon, bringing together the two leading humidification companies. The 1980s also saw expansion into North America with the acquisition of Nortec, a significant distributor for both Defensor and Plascon, along with the rebranding of Plascon to Condair.

The organisation continued to grow and develop until 1995 when the world’s largest humidification company was formed with the fusion of the Defensor and Condair companies under the new name of Axair. Further acquisitions in the sector resulted in a total of 12 humidifier companies being owned by the Walter Meier Group by 2012.

The decision was then taken by the principal shareholder, Silvan Meier, to consolidate operations under the motto of “one brand, one company” and bring together all its interests in the humidity control sector under the banner of Condair.

Damien Power continues: “Today Condair operates sales and service organisations in 23 countries, has distribution partners in a further

50 regions, and manufacturing facilities in Asia, Europe and North America. The company has been the driving force in the sector, having invented systems such as the electrode boiler steam humidifier, which is probably the most widelyused type of industrial humidifier in the world.

“The company continues to innovate with new smart features such as IoT connected devices. In addition, innovative new products like centrally managed, whole-house residential humidifiers, controlled by a phone app, are again pushing the boundaries for the industry.

“Condair also champions the positive purpose of the sector. The company’s slogan of Humidity for a better life communicates both the health benefits of maintaining an optimum indoor humidity, alongside the more traditional manufacturing benefits. We deliver solutions that protect people’s health and we’re committed to increasing awareness of this, and to fulfilling our duty to make the built environment healthier. We are very proud of our company’s values and heritage over the last 75 years, and of the major industry firsts we have unveiled over that time.” concludes Damien.

Hitachi residential and light commercial …

All-in-one cooling, heating and DHW solution

The Carbon Trust’s latest findings report that heat pumps can deliver CO2 savings of up to 65% compared to even A-rated gas boilers, and with heating and cooling making up +/- 50% of a building’s energy consumption, replacing fossil fuel heating is one way to reduce commercial operating costs as the cost-of-living crisis bites.

Exhaust air heat pumps are gaining momentum in Ireland for highly-insulated new-build properties with low energy requirements (such as apartments), avoiding the need for expensive wet central heating or gas installations. But larger properties or refurbishment projects are better suited to air source heat pumps, where a higher capacity rating is required.


Using low GW R32 refrigerant and reduced charge volume, Hitachi’s Yutampo split heat pump water heater has typically been installed in new or refurbishment residential applications for domestic hot water (DHW) where there are existing fuel setups for heating.

Let’s not forget commercial applications. Yutampo R32 can be installed in small to medium commercial sites where existing heating systems provide the heat but DHW is required.

• Yutampo R32 is the first fully EN378-compliant heat pump water heater on the market;

• With a high COP of 3.2, it is highly efficient, delivering 3.2kW of heat for every 1kW of electricity it uses;

• Produces DHW up to 55o as a standalone tank/outdoor unit setup (up to 75o with an electric heater add-on);

• Remote control via the HiKumo customer app and HiKumo PRO for easy remote maintenance.

Yutampo Multi

Hitachi’s newest Yutampo is the first multi on the market to provide triple comfort: cooling, heating and DHW from one outdoor unit. It combines air conditioning for cooling and heating, and a split water heater tank (190L or 270L capacity) for DHW.

Yutampo Multi is also suitable for refurbishment housing, replacing electric heating systems/boiler setups and newbuilds with high demand for energy efficiency, low capacities and smaller installation spaces, and light commercial applications where up to four indoor units can supply ambient cooling and heating as well as DHW requirements.

Priority control

With smart Priority Control, users can choose to prioritise heating/cooling or

hot water. This is perfect for domestic settings with high hot water demand, or offices and retail spaces needing to maintain a comfortable working temperature.


• High seasonal performance SEER A++/ SCOP A++/A+;

• Increased energy savings with Hibernate mode (70% reduction of standby power consumption);

• 5.3, 6.8 or 8.5kW capacity outdoor units;

• Choose from wall-mounted, floormounted, ducted or cassette indoor units;

Wavin harnessing BIM innovation

When Ireland’s National BIM Council published its Road Map to Digital Transition for Ireland’s Construction Industry in 2017, it recognised that BIM was “at the centre of a digital transformation of the construction sector and the built environment across the world”.

Since then, BIM has been the catalyst for a range of new technologies and digital practices that are creating a competitive advantage for the Irish architecture, construction and engineering (ACE) firms that embrace them, writes Michael O’Donohoe, Country Director, Wavin Ireland. This is a pivotal moment for the sector and BIM-mature organisations are racing ahead in terms of innovation and efficiency. As Dr Barry McCauley, Head of Geospatial Surveying and Digital Construction at Technology University Dublin (TUDublin) summarises: “Ireland is on a really good trajectory – we’re a small nation that can react well. Today, there are a lot of good courses, events and investments happening, as well as

continuing professional development. We’re even getting to the stage where many graduates are applying their learnings and starting new, forwardthinking businesses across the technology, construction and development space.”

Some of the exciting technologies that will impact the ACE industry in the coming years, and enhance project delivery for those poised to adopt them, include:

IFC and cloud computing

As BIM Level 2 becomes established as the industry standard in Ireland, full cloud migration is helping both on and off-site workers to access and modify designs from anywhere.

Virtual reality

BIM rendering software, like AutoDesk 3Ds Max, offers immersive 3D experiences of ACE designs. Using this software, it is possible to take stakeholders on simulated walkthroughs from the first stages of the design process.

Machine learning (ML)

The adoption of Artificial Intelligencepowered ML technologies, like the AutoDesk 360 IQ BIM platform, offers countless possibilities for advanced decision-making and high-speed analysis across Irish construction projects.

Digital twins

Digital twins, digital replicas of their physical counterparts, are a major growth area for the Irish construction sector. A step closer to smart cities and BIM Level 3, when intertwined with the IoT, they support long-term functions like facilities management and maintenance.


By taking over manually-intensive and repetitive tasks, BIM automation will increase efficiency across the Irish construction sector and reduce potentially-costly mistakes. It also allows designers to focus on creative and complex problem-solving, while automation carries out tasks such as structuring data, naming files, automating design conditions and predicting variables.

Harnessing BIM innovation

Wavin is harnessing BIM innovation in Ireland through its Revit content packages with integrated intelligent assistance. With this intelligent assistance, an accurate installation model of a pipe system can be reached in BIM in the fastest way possible. This new way of working will significantly reduce time spent on design. The Wavin Revit packages allow users to reach a 100% accurate representation of the way piping systems will actually be installed, easily and without the use of product catalogues. The package also features a fully-integrated Bill of Materials. Significantly faster to use than competitor packages, precise models can be created in a fraction of the time and be fed into a project earlier. By automating key aspects of pipe system design, the intelligent assistance in the Wavin packages speeds the process and removes the risk of costly errors being made. Wavin is the only BIM content to feature a visual accuracy check.

Thermal energy storage eSTÓR – better heating for a better tomorrow

While much of the emphasis on the current drive towards electrification and the use of renewables in heating and DHW is on the heat source, there is a growing awareness that thermal energy storage is now more critical still. It is against this background that Unitherm Heating Systems, working closely with a leading American expert in the field, has developed eSTÓR.

eSTÓR comprises a range of modular phase change material (PCM)-based heat batteries that store thermal energy for use in domestic hot water and space heating applications. In an industry first, eSTÓR units are powered by a smart PCM (Bio-PCM) that is precisely tuned to work with heat pump technologies, and equipped with an intelligent integrated back-up heater system that supports direct connection with PV systems.

Future of hot water storage

Conventional steel hot water tanks are produced using energy-intensive processes (mining and the processing of raw materials at high temperatures), and they suffer from high standby heat losses. This all contributes to wasteful carbon emissions.

In contrast, eSTÓR heat batteries are conscientiously designed to be produced in a manner that reduces carbon emissions in both the manufacturing process and with

regard to transportation. This contributes to the circular economy, aids water conservation, yet still delivers copious amounts of instantaneous hot water.

Sustainable and renewable

Using only Bio-PCM, eSTÓR heat batteries have sustainability at their core. Bio-PCM, sourced locally from

100% renewable resources, is a high energy density, non-toxic and biodegradable smart material, providing a local source for local solutions to home energy needs.

Utilising the increased energy density of Bio-PCM, eSTÓR heat batteries store more thermal energy in a smaller overall volume. This results in a more compact system design with a greatly-reduced external surface area through which heat energy can be lost. This more compact size, coupled with the highly-insulated tank and the self-insulating properties of the Bio-PCM, results in extremely low standby losses, providing unrivalled long-term energy storage with reduced energy wastage.

Grid stabilisation

In addition, eSTÓR’s exceptional energy retention performance and its high energy density provide the national grid and utility providers with a demand response/load shifting option for “time of use” planning. This supports stabilisation, while also offering homeowners the ability to store heat energy during lowercost, off-peak times for use when needed, thereby maintaining thermal comfort at all times.

“Designed today for tomorrow’s homes,” says Declan Kissane, Director, Unitherm Heating Systems, “eSTÓR is a pioneering technology that has already been lauded, having recently been highly-commended in the Innovation Category of the SEAI Energy Show Product of the Show Awards. It is also a responsible technology contribution designed to help achieve the global objective of building a cleaner, more sustainable and safer planet for future generations to come.”

Building resilience into systems that are fit for the future

Kevin Devine, Sales Director, Xylem Water Solutions Ireland, outlines ways in which the latest tech can power Ireland’s drive for energy efficiency on the journey to net zero carbon emissions.

Sustainability is the key issue of our time. As well as the responsibility to protect the planet for future generations, it calls for resilience in the face of changing weather patterns, fluctuating fuel prices and dwindling resources.

The energy-hungry building sector has been identified as crucial to help achieve the EU’s energy and environmental goals, and developing more energyefficient solutions is a vital piece of the puzzle. With HVAC energy consumption accounting for more than 40% of a commercial building’s total energy use, for example, we know there are savings to be made.

Overhauling systems to meet new targets comes with a cost, but that’s where retrofitted solutions can bring real value, creating building systems fit for the 21st century without the hefty price tag.

I heard Ian McAulay, former Chief Executive Officer at Southern Water, said something about investing wisely that stuck with me: “Capex is for Christmas, but Opex is for life”. That is why at Xylem we are helping clients across Ireland prioritise sustainable longterm solutions with the help of bolt-on, built-to-last solutions, as well as new platforms that help identify incipient issues and enable the move from reactive to proactive maintenance. We’ve even appointed a business development manager to focus on building services specification, and to work with the consulting engineering community to deliver bespoke solutions and support the delivery of energy contracting services.

High-tech lowers energy usage

Xylem’s Lowara Hydrovar intelligent variable speed pump controller, named Best Energy Efficient Product at the SEAI Energy Show, controls the speed of a motor to match performance to demand. By adjusting performance in this way, it ensures pump systems only use the energy that is necessary, saving up to 80% at partial loads alone.

Retrofitting energy efficiency

Existing fixed speed pumps no longer have to equal higher bills. A motor running at 80% of its maximum speed uses 48% less energy, making add-on controllers like the fifth generation Hydrovar an essential part of a building manager’s toolkit to bring pumping systems rapidly up-to-date and meet challenging energy efficiency requirements, as well as saving on bills.

Operating smarter

Xylem’s Smart Asset Management

(SAM) framework connects with any motor-driven asset to provide real-time actionable data on performance for maximum efficiency. It creates a digital twin that allows users to optimise systems through monitoring and analysis of historic, current and future asset condition, minimising ad hoc service calls and prioritising service workflows.

Benefit from digital development

As Ireland takes steps to meet a minimum 55% EU reduction in greenhouse gas emissions by 2030, buildings are being challenged under the Energy Performance of Buildings Directive (EPBD) to reduce energy use. New regulations have established minimum energy performance requirements for new buildings, for existing buildings undergoing major renovation, and for the replacement or retrofit of HVAC systems, roofs and walls.

To make smarter use of Opex, energy efficiency and sustainability are key. In addition to meeting energy and environmental goals, more energyefficient buildings will improve quality of life and ease energy poverty. With reuse among the central principles of sustainability, retrofitted solutions have a major role to play. Other digital tools can help building systems operate smarter via round-the-clock monitoring to offer insights into both energy consumption and performance.

Ireland supports ‘whole life carbon’ initiative

Ireland, Czechia and Spain will be the first countries to participate in a new initiative which aims to boost the availability of quality building climate data. This is a critical step towards decarbonising the heavily-emitting sector, which is responsible for almost 40% of global emissions.

According to a recent press release from the World Green Building Council, the INDICATE initiative will bring together governments, industry and academia to tackle one of the most common barriers to enacting policies which will ensure climate neutral construction.

INDICATE seeks to accelerate policy development across Europe by generating critical baseline data for buildings to help guide policymakers in setting carbon limits that cover the full lifecycle impact of buildings, from manufacture and construction, through to deconstruction and waste processing – the so-called “whole life carbon limits”.

Currently, almost all building regulations in Europe only address carbon emissions from the building operation, ignoring the emissions that are generated before a building comes into use and at the end of its life1. These embodied carbon emissions – which together with operational CO2 are known as whole life carbon – can be

more than half of a new building’s total carbon footprint and threaten to consume national construction carbon budgets well ahead of 2050 net zero goals.

Certain leading markets like Denmark, Finland, France and the Netherlands have already enacted whole life carbon policies. The first crucial step in setting these was to establish baselines. Other European countries are held back from following this example due to a lack of necessary data2

The coalition behind INDICATE is tackling this data gap. The public-private approach of the project aims to secure broad support and investment for the results from industry and policymakers alike, helping to ensure the resulting data can be quickly put to use. This is just the beginning of what the coalition hopes will be a European-wide programme to finally quantify and drive a quick reduction

in unregulated carbon emissions.

The EU recently took its own first steps towards whole-life carbon regulation with proposals to introduce mandatory reporting in the revision of a key piece, the Energy Performance of Buildings Directive (EPBD). By strengthening political support and industry capability among more countries, INDICATE will help to overcome opposition seen from some member states to the ambitious proposals EU lawmakers have put forward for the EPBD revision.

The Irish partners in the three newlylaunched national pilots are the Irish Green Building Council and University of Galway. INDICATE is being carried out through Construct Innovate, Ireland’s national research centre for construction technology and innovation. The lead partners already mentioned are being supported by the SEAI, University College Dublin and associate members of Construct Innovate.

Joe Durkan, Head of Technical – National Retrofit, SEAI (pictured) said: “High quality data on whole life carbon emissions associated with our built environment is critical to support policymaking and decarbonisation of our building stock. SEAI recognises the importance of collecting standardised data through the development of a national methodology to assess these emissions and is pleased to support the INDICATE project.”

IRI conference draws capacity attendance

The Institute of Refrigeration Ireland (IRI) recently held its biennial conference at the Green Isle Hotel, Dublin. A capacity attendance of over 100 delegates took part in what was a very informative occasion with a speaker line-up comprising 14 industry experts.

The conference is normally held every two years but this particular event was the first one since 2019 due to the Covid pandemic. The main theme was “Decarbonisation and net zero, the role of heat pumps and refrigeration heat recovery.” The main discussion points centred around Ireland’s national decarbonisation targets, the RAC industry’s role in meeting them, the ever-changing rules and regulations being introduced to drive the change, and the new technologies coming on stream to achieve these aims.

Series of excellent papers

The conference programme saw the 14 expert speakers deliver a series of excellent papers on everything from green building certification to the new national Irish standard for heat pumps. They came from a wide range of industry bodies such as the ESB, EPA, TUD, SEAI and Codema,

and various businesses involved in RAC and heat pumps. This resulted in a broad-ranging and highly-educational conference with delegates gaining as much from the ensuing Q&As as they did from the papers themselves. Selecting a main theme for the conference is the task of the IRI’s Technical Committee, which is chaired by Declan Fitzmaurice of FTG consulting. The aim is to incorporate topics which have a current relevance for the RAC industry. Delegates attend a series of talks and are brought up to speed on the latest technologies, trends and regulations which affect their jobs and businesses. The recent conference fulfilled this objective and also provided the opportunity for delegates to network and exchange ideas with their peers.

Panasonic to unveil new Aquarea K and L ranges at the Guinness Storehouse

Panasonic Heating & Cooling Solutions is to host an evening at the iconic Gravity Bar in the Guinness Storehouse, Dublin, on 14 June next, to mark the introduction of the new Aquarea K and L ranges of air source heat pumps. In addition to the formal presentations, examples from both ranges will also be on display, while food and refreshments will be served throughout the evening.

The event will see VIPs from Panasonic joining guests to enjoy the experience. These will include Hiroshi Komatsubara, Head of PHVAC Europe and Jose Alves, Country Manager, UK & Ireland.

“An event not to be missed,” says Vincent Mahony, Ireland National Manager, Panasonic, “the evening promises to be an inspiring occasion for our guests who will have the opportunity to not only learn about the innovative K and L ranges, but to network and engage with like-

minded professionals about delivering more sustainable heating solutions. The new Aquarea K and L ranges were specifically designed to meet this brief.”

The L generation uses the natural refrigerant R290, which has a Global Warming Potential (GWP) of only 3, and can supply water temperature of up to 75ºC. The units also have a market-leading efficiency of 5.05 CoP, feature a hydraulic link, and are hermetically sealed for both easy and flexible installation.

Meanwhile, the K generation utilises R32 refrigeration, making it an excellent solution for new homes. Furthermore, it retains a refrigerant link between the outdoor unit and the indoor unit.

The redesigned construction of the outdoor units of both generations provides a high level of safety.

Both the K and L ranges benefit from a reduced noise level which is up to -8dB(A) less than previous models. They also offer an even higher level of performance for greater savings, boasting an improved SCOP of up to 5.12.

Full details of both the K and L ranges will be unveiled at the forthcoming event in the Gravity Bar at the Guinness Storehouse. Representing an investment of almost €20 million, the Gravity Bar offers extended panoramic views of Dublin. Constructed as a figure of eight, it is designed to give visitors maximum views across Dublin’s city skyline, including the Phoenix Park and the Dublin Mountains. The venue has a limited capacity of 300 guests and places are filling up fast.

Grant’s innovative heating technologies

The importance of sizing heating systems

Leading heating manufacturer, Grant, is renowned for its innovative range of reliable and sustainable heating technologies. Designed with the property developer, architect and homeowner in mind, Grant’s innovative heating technologies work together seamlessly.

This means that those working on new-build properties can save time on the project by having the full heating system designed and specified under one roof, using the best-suited products. This results in a highly-efficient, compliant heating system.

With a focus on maximising efficiencies and reducing carbon emissions, the technical team at Grant uses experienced insights to design bespoke integrated heating packages. These include sizing and specification of all technologies to suit the property, and the property owner’s preferences. This in turn helps the new-build to achieve compliance,

while benefitting from the high efficiencies for which Grant heating technologies are renowned.

When it comes to upgrading or installing any heating system, the correct sizing of the technologies used is vital to ensure the system runs efficiently. Sizing requirements are based on the heat load requirements for each room in a property, and these calculations can also determine the best-suited technologies for the project.

A common misconception is that a bigger main heat source results in a more effective heating system. This is not the case. A heating system that has not been sized in line with a property’s requirements is most likely to produce inconsistent heat using more energy, leading to increased heating costs, reduced efficiency, potential maintenance issues and the heating system not living up to expectations.

Before upgrading any heat source, whether it is a Grant Aerona³ R32 air to water air source heat pump or a Grant Vortex condensing boiler, it is important to consider the age of the current system and the property’s structural

and aesthetic features before deciding on the size of the new heat source and complementary technologies.

Specifically, if the homeowner wants a Grant Aerona³ R32 air source heat pump installed as the main heat source, the property must be air-tight in terms of insulation, with loft insulation, double-glazed windows and cavity floor insulation all recommended.

In addition to individual self-build properties, Grant also works closely with builders, developers, architects, BER assessors and installers to provide its integrated heating package solutions for both large and smaller housing developments. Dedicated to ensuring a simple process for the builder and installer, the Grant technical team designs the full integrated heating package for properties of all sizes, within developments or single dwellings, free of charge.

The team also works closely with all involved in the property build, throughout all stages of the build journey, to provide support and assurance in terms of correct product selection, sizing, specification and ensuring compliance.

FläktGroup – ‘Treating air means mastering it’

When it comes to providing heating, cooling, filtering, humidification and dehumidification, FläktGroup offers highly-efficient air treatment and control solutions that deliver the optimum indoor environment combined with maximum energy efficiencies. In addition, and especially in the highly-sensitive areas of clinical and clean room applications, these solutions also satisfy all international standards and achieve high rankings in the classification of the “Eurovent Compliance Committee for Air Handling Units”.

Unlike radiators and classical flat radiators, FläktGroup fan-coil units not only heat rooms, but cool and ventilate them. They offer all the possibilities of demand-controlled ventilation (DCV) and can be employed everywhere where comfortable warmth, cooling or air ventilation, with a rapid adaptation, is required.

FläktGroup fan-coil units actively guide the air to be processed through the heat exchanger, whereby it is heated and cooled effectively. They bring the room air to the desired temperature faster and operate with smaller heating or cooling surfaces. Their enhanced heat

transfer enables lower feed temperatures during heating, and higher feed temperatures during cooling. This minimises losses and saves energy between the boiler or the chiller and the final unit. The range is extensive with three of the latest additions being the HyPower-Geko, the HyFlex Geko and the HyCassette and Cassette Geko units. Brief details of each are as follows.

HyPower-Geko – These compact units are installed in a discreet position above a suspended ceiling and can be connected to both the heating and chilled water supply grid. Despite the high power capacity, HyPower is

distinguishably quiet. The modular construction allows a flexible design.

HyPower comes in three versions – with or without fan chamber, as well as with fan chamber and inner acoustic insulation. Among the 2-pipe systems, there are three capacity stages with up to six tube rows available. For the 4-pipe systems there are two selectable capacity stages.

HyFlex-Geko – This unit creates a new level of flexibility and performance. During its development, every single technical component was optimised to maximise performance. As a result key benefits are flexibility, high performance, hygiene, quick selection, simple installation and easy maintenance.

HyCassette – This new type of fan coil unit with swirl air outlet technology sets new industry benchmarks. By meeting the highest comfort standards with its intelligent control system and its attractive design, this system is the answer to all air handling requirements.

ISYteq – ISYteq Touch 4.0 is a microprocessor-based, programmable electronic controller that enhances the control of any facility for the developer, building owner, installer and facility manager. The modern tile layout makes navigating the system very easy and the touchscreen offers precision control to enable low fan noise or boost heating and cooling. Available in black or white frames.

Innovative dry-fit UFH system from Unipipe

The unique Ideal Classic NEO 20 underfloor heating system from Unipipe is designed to be installed without the use of wet screed and, at just 20mm high, is ideal for use upstairs in timber floors and in homes with engineered joists. The underfloor heating pipework is fitted into shallow pre-engineered EPS boards, with an aluminium coating that helps to transfer heat optimally into the floor finish above.

The Ideal Classic NEO 20 system is an adaptation of the established Ideal Classic EPS 30 devised by renowned German manufacturer MFH. The advantage of the latest version is that the installation height is reduced by 10mm, while a 16mm heating pipe is still used, meaning that the heat output and pressure loss remain identical.

The system elements are laid according to the usual, simple principle of the MFH Ideal system. The 0.5mm thick aluminium

heat-conducting sheets are already attached to the NEOPOR and the pipe channels have an omega shape to optimally fix the 16mm pipe. Floor coverings can be laid (almost) directly on the heating elements.

Ideal Classic NEO 20 can be combined with all common screeds and is particularly suitable for drywall construction. In combination with innovative heat-conducting layers, a high level of heat output is achieved and rapid heating up and down is possible, making it particularly energy-efficient.

“These underfloor heating systems are ideal for new-build or retrofit,” says Paul O’Donnell, Managing Director, Unipipe, “and challenge the misconception that underfloor heating is too awkward and difficult to install on the first floor and above. Apart from the comfort and performance levels, it also offers a solution for those who don’t want radiators cluttering up wall space.

“We also supply a strong, 5mm board made from recycled materials which, when placed over the MFH 20mm boards, can then take the laying of ceramic tiles. This solution is ideal for apartments and also offers the added benefit of soundproofing the floors.”

Features and benefits

• Easy-to-install with a low installation height;

• An installation height of 40mm, including flooring, is possible with CompactFloor;

• The 16mm pipe can also be used at a low height;

• Technically compatible with the Ideal Classic EPS 30;

• Flexibility and efficiency in one system.

Boosting performance with pre-insulated ductwork

Ductwork is a core component of most building services systems, but it can be cumbersome and time consuming to both fit and then lag, particularly in light of the energy performance of the systems coming under greater scrutiny. Pre-insulated phenolic ductwork systems can help to address these challenges by supporting faster installation and greater on-site adaptability. They also deliver air-leakage rates that can be a fraction of those of conventional ductwork, potentially reducing system operational energy demand and cost. John O’Gorman, National Sales and Specification Manager, Kingspan Technical Insulation Ireland, explains.

Faster fit-outs

Galvanised steel ductwork has been the standard solution for building services applications for decades. While durable, it is also heavy. This means sections need to be fitted in short lengths and supported with a lot of hangers/supports. In addition, once the ductwork is installed, it then needs to be lagged with insulation as a separate activity.

This adds a lot of time to the install process and means the ducting must

be fitted with a sufficient gap from the wall or ceiling.

In contrast, pre-insulated ductwork systems are formed from rigid phenolic insulation panels faced with aluminium foil on both sides. These panels can be used to fabricate ductwork in sections up to 2.95m long. With no need to install insulation in a second fix, the runs can be fitted flush with floors, walls and ceilings, saving up to 200mm in a single dimension. Pre-insulated phenolic ductwork can be as much as 75% lighter than a comparable sheet metal system with mineral fibre lagging. In addition to reducing structural support requirements, this lightweight design means it is possible to join several sections of ductwork together at floor level (up to 15 meters in length) and lift and fit them in a single operation. The pre-insulated panels can also be easily modified onsite, making it much easier for site teams to manage unexpected changes to the design.

Energy savings

Pre-insulated phenolic ductwork can also offer clear operational advantages. The low thermal conductivity of its rigid phenolic insulation core makes

it the most thermally-efficient, and hence the thinnest, insulation product commonly used for pre-insulated HVAC ductwork.

The fabricated ductwork sections can also be highly airtight and are capable of meeting air-leakage Class C and D, both at low and medium pressures (ref. BS EN 1507: 2006; BS EN 13403: 2003 and BESA DW/144). This can allow the desired airflow rates to be met with smaller, more efficient fans, potentially significantly lowering long-term energy demand.


Building services specifiers face a range of challenges, from labour shortages to ambitious energy targets. Preinsulated ductwork offers a premium performing solution which can be quickly and easily installed and can adapt to changing building plans.

Listen, understand, deliver … Mitsubishi Electric – customer support par excellence!

Nonetheless, best-in-class customer support is now an essential requirement for all businesses. Having an excellent product portfolio is one thing but, without the same level of customer support, a company can lose existing customers and even fail to attract new ones.

This is particularly so given the scope and applications base of the Mitsubishi Electric Living Environmental Systems (LES) product portfolio. The rapid pace of technology development, coupled with a continuous stream of new products, means that customers are

constantly faced with new innovations and related support systems.

Dedicated Customer Support Division Hence the dedicated Customer Support Division at Mitsubishi Electric.

Once selected, place the relevant spare part(s) in the “basket” and they will be shipped straight away.

everything from technical and engineering roles through to order processing, logistics, project scheduling, stock issues, transport and even regulatory compliance issues.

But even that alone is not sufficient. How this service support is delivered is the most critical issue. Marta McCarthy explains: “The most important qualities of good customer service comprise an ability to listen to, and understand, the customer’s query or problem, and to then deliver a solution in a positive, efficient and timely manner.

“It’s a case of a ‘people first’ approach where our team members genuinely engage with the customer so that we respond to their unique situation rather than impose a standard solution which may not be appropriate.

While virtually everyone recognises good customer support when they experience it, it is something that is very hard to define and describe.

As the world continues to grapple with the ongoing and pressing issue of climate change, it has become increasingly apparent that the role of the engineer is of utmost importance. Consulting engineers, in particular, are at the forefront of design and construction of infrastructure that can withstand and adapt to the impact of climate change, as well as the development of sustainable technologies that can help reduce emissions and mitigate further damage to the environment.

However, like many other industries, the consulting engineering sector is currently experiencing a shortage of skilled workers, with women being significantly under-represented in this highly-skilled profession. Attracting more young talent is essential if we are to respond to the climate emergency. Against this backdrop, the gender gap is both a cause for concern and an opportunity, especially as we need all the talent and diversity we can get to address the challenges of climate change.

EFCA Conference

Now, as the European Federation of Engineering Consultancy Associations (EFCA) prepares for its forthcoming conference on “Delivering Climate resilience: How the European green deal, digitalisation and harmonised standards present

54 Building Services Engineering l May/June 2023
The disparity not only limits opportunities for women but also has broader societal impacts.

opportunities for engineering consultancies” and General Assembly in Rome (31 May to 1 June 2023), it is an opportune time to reflect on women in engineering.

Here, Inés Ferguson President-elect of EFCA, places a special focus on Ireland and the EU, and considers what can be done to bridge the gender gap and promote greater diversity and inclusivity in the field.

Persistent gender gap

Sarah Ingle, the former SecretaryGeneral of the Association of Consulting Engineers of Ireland (ACEI), emphasises the importance of women in engineering and the positive impact they can have on sustainability and society: “As the first woman in Ireland to graduate with a degree in Production Engineering from Technological University Dublin (formerly DIT), I strongly advocate engineering as a great career opportunity for women to help address sustainability concerns for our planet and make a real difference to society. Women bring special traits, skills and ways of working to projects, and a diverse team of engineers and other professionals will always produce the most successful outcome.”

However, recent data suggests that women remain significantly underrepresented in the engineering workforce, both in Ireland and internationally. In Ireland, only 12% of engineers are female, while the figures for the United States, Australia and India are 13%, 14% and 14% respectively. That said, there is some good news. Eurostat data from 2022 suggests that the representation of women in engineering and science jobs is on the rise across all EU countries. Data shows that at thirdlevel education, 23% of engineering graduates in Ireland are female. For the ACEI this shows the long distance to travel by the profession to attract and retain female talent in engineering.

The disparity not only limits opportunities for women but also has broader societal impacts. It can

discourage future generations of girls from pursuing careers in engineering, as they may not see women represented in the field. There is a lack of female leadership, especially in management positions. For example, in the heavy construction sector, which includes civil engineering, only 1% of CEOs are female.

EFCA community ‘bridges the gap’ EFCA and its community is committed to promoting diversity and inclusivity in the industry. At national level in Ireland, the ACEI’s new strategy “Bridging the Gap” identifies diversity in the consulting engineering profession as a key strategic objective. As a result, the ACEI will be delivering a series of existing and new initiatives over the coming five years to move the dial in diversity. These will include, inter alia, increasing female participation across all committees within the Association, executing a “see it to be it” social media campaign featuring leading women in the sector, and collaborative initiatives with other bodies in the profession, for example, in ensuring that girls-only secondary schools provide STEMD subjects.

To support these national efforts, EFCA believes that the European Year of Skills 2023 presents a unique opportunity to promote engineering as a viable career option, especially for women, from an early age. By dismantling the barriers that limit

diversity and inclusivity in the engineering industry, we can better equip it to tackle future challenges and create a brighter future for all.

As part of the “EU Pact for Skills”, EFCA has made a commitment to address these challenges through various initiatives, including workshops, capacity-building training, and the Future Leaders’ Competition. These efforts aim to promote STEMD education, inspire and engage young people in engineering, and equip engineers with the necessary skills to thrive in a rapidly-evolving digital landscape.

Change of EFCA Presidency

At EFCA’s imminent conference and General Assembly in Rome, Inés Ferguson, Director of Business Development at TYPSA and the current EFCA President-Elect, will take over the presidency from Benoit Clocheret, the outgoing EFCA president. This is a significant milestone as Inés will become the first-ever female president of EFCA. Ferguson is a strong advocate for diversity in engineering and will use her term as president to further this goal. She says: “Diversity raises the performance of the consulting engineering industry. In particular, female talent brings greater flexibility, collaboration and communication. This drives new solutions, integrates teams and promotes partnerships to inspire a positive change.”

By attracting and retaining talented individuals, promoting innovation and creativity, and motivating the upcoming generation of young engineers and construction professionals, the industry can establish a better future where everyone has an equal chance to excel in their chosen field.

EFCA believes that by promoting diversity and inclusivity in the field, and by encouraging young people, especially women, to enter the field of engineering, we can design a future, climate-resilient, built environment and make a significant impact.

Thermodial completes management buy-out

The Thermodial management team of Turlough Kinane, Alan Keegan and Mark Carrick recently completed the 100% buyout of the company, having already acquired 55% in 2016.

The buyout sees Kinane, as Managing Director, Keegan, Operations Director and Carrick, Projects Director, acquire the remaining 45% shareholding, giving the trio 100% ownership of the company with each having an equal shareholding.

The goal now is to increase the turnover by 30% to €13 million and to further grow employee numbers to over 100 people by 2026.

Established in 1986, Thermodial is now a leading operator in the installation and maintenance of commercial HVAC and building energy management systems (BEMS), in addition to providing a suite of planned preventative maintenance programmes that can be tailored to specific customer needs.

Based in Dublin, but with a national reach, Thermodial recently moved to new premises to facilitate its planned expansion, accommodate its growing workforce, and increase its stockholding of products and spares. This will ensure

a more efficient and streamlined service to its broad customer base which includes retail, public sector, education, hotel and leisure, datacentre and healthcare sectors.

Commenting on the acquisition, Kinane said: “Over the decades we have built a strong reputation in the commercial heating and ventilation market and have been successful in being accredited with four ISO standards. That combination of client trust and expertise has enabled us to broaden our services and to grow the BEMS side of the business.”

Team strength

Alan Keegan takes up the story: “Underpinning this development is the strength of the Thermodial team. We have an excellent mix of personnel across all disciplines related to HVAC and BEMS. This mix of highly-qualified and experienced engineers and crafts people provides

us with a diversified base on which to continue our growth pattern.

“Longevity of service is another factor with the vast majority of employees working with the company for 10 years or more.”

Thermodial is a strong advocate for CPD (continuous professional development) and, apart from its own in-house training programmes, it also engages with its supply partners to avail of their training modules. The recruitment policy is to employ the best. In addition to taking on qualified personnel from the open market, it has a long-established apprenticeship scheme. Growing its own has proved extremely productive and it currently has 14 apprentices at various stages within the qualification process.

The nature of the services provided by Thermodial has changed and adapted over the years in order to accommodate the ever-evolving market needs. Merely preventing company downtime and disruption to production is no longer good enough. This now has to be done in a sustainable manner that delivers significant energy savings, while also lowering carbon emissions.

Mark Carrick explains: “We are committed to ensuring our clients are environment-friendly businesses and all the services we provide are designed to help achieve this goal.

“However, we also apply the same pro-active approach to minimise the effects we ourselves have on the environment. We always strive to use renewable resources wherever possible, and are committed to reducing waste generation through conservation and recycling measures. We comply with all current Irish and EU regulations and plan our training needs in advance of any new regulatory developments we see coming down the line.”

Thermodial’s mission is to achieve market leadership by providing effective technical solutions which exceed customers’ expectations. It is perfectly set up to do just that.

Incorporating “fire tube” heat exchanger

Nesta Plus range expanded to 1260kW capacity

The AIC Nesta range of floor-standing, highefficiency condensing boilers from C&F Quadrant is suitable for either medium or large residential and commercial installations. They are perfect for both retrofit or new-build projects, and are available in a choice of options from 120kW right up to 1260kW.

In fact, AIC just recently expanded the Nesta Plus range with the addition of new floor-standing condensing boiler models that come in outputs of 350kW, 1080kW and 1260kW. They are particularly suitable for commercial and industrial installations requiring greater thermal output.

The standard electronic controller on the Nesta Plus is designed for the management of up to six boilers in cascade. This also controls the boiler management functions and alarms, in addition to a multicircuit installation, when utilising additional accessories.

lt is also possible to manage the boiler, cascade and the entire system via the ethernet network or GSM router (with WEB Server Module).

The high water content (up to 600 litres) helps promote operational stability and a high

efficiency of yield (108%). The small footprint and compact dimensions means they can be installed in areas where space is at a premium.

Nesta features and benefits

• Stainless steel heat exchanger;

• Self-cleaning flue ways;

• Internal circuit piping in welded stainless steel;

• Low pressure drop;

• Compact dimensions;

• Reduced maintenance;

• Can be installed in cascade up to six boilers;

• Low NOx levels;

• Lifting points for transportation and positioning.

The Nesta Plus high-output, singlepass condensing boilers have an

impressive 7:1 modulation range that provides high seasonal returns and significant savings on gas consumption. Linear modulation addresses the needs of higher output plantrooms and allows the boiler to consistently achieve maximum efficiency, limiting boiler cycling as much as possible. This technology is effective in both new-build and retrofit heating systems. The Nesta Plus controller enables remote boiler management by web server connectivity. One of the primary benefits of this advanced integrated control system is the optimalisation of periodic servicing using self-diagnostics to assist the engineer prior to attending site.

At the core of all Nesta boilers is AIC’s stainless steel “Fire Tube” heat exchanger technology. The use of high-grade stainless steel alloys ensures product durability, reliability and higher resistance to corrosion and oxidation.

The completely immersed flue gas tubes of the “Fire Tube” exchanger, with their high heat transfer coefficient between water and smoke, ensure an optimal counter-current exchange over the entire length of the exchanger. This allows AIC condensing boilers to reach very high efficiency, without the risk of oxidation. Another advantage is the selfcleaning feature. The unique design and orientation of the heat exchanger allows the condensate to run down the inside of the heat exchanger tubes and cleans any possible traces of combustion residue. This function allows the boiler to maintain maximum efficiency throughout its lifespan, leading to reduced running costs and maintenance for the end-user.

ActionZero heat pump delivers rapid decarbonisation

With heat accounting for 50% of energy use globally and up to 40% of global C02 emissions, the energy transition and move to a more sustainable global economy cannot be delivered unless we decarbonise heat.

ActionZero, a Cork-based climate technology company, has developed a high temperature heat pump technology, the EscoPod, which it believes will be a disruptive game-changer in the rapid decarbonisation of heat.

The award-winning, patented EscoPod was designed to replace traditional heating systems with a high-efficiency and fossil-fuel-free alternative, and is said to reduce carbon emissions, energy use and even costs by up to 70%. It produces multifunctional outputs and will seamlessly integrate into process heating, space heating, domestic hot water and cooling systems.

A unique feature of the EscoPod when used in space heating applications is that it does not require a deep retrofit to install as the system can deliver output temperatures of up to 80°C for space heating circuits. This offers many organisations a lifeline, a realistic pathway to decarbonise their operations without enormous cost and business interruption.

In terms of application, the EscoPod range has been designed specifically to deliver heating and cooling across industry, healthcare and difficult-todecarbonise commercial buildings.

How EscoPod works

Designed and built in Ireland, some of the key features of EscoPod include the use of an economiser circuit, subcooling, optimised defrost cycle management and premium components for extended design and operations life.

In any heating system heat will flow in one direction only – from a hightemperature source to low temperature sink. Therefore, in an 80°C heating system with a water return temperature of 70°C, only 10°C of heat can be removed from the refrigerant, despite the refrigerant being heated from below ambient air temperature to above 80°C.

Some alternative high-temperature heating systems on the market are typically suited to heating water with a low inlet temperature, such as mains water, as they depend on heat transfer

(from cooling the liquid refrigerant to low temperatures) to operate efficiently.

Up to now, a system with high water return and flow temperatures had to have a significant amount (70°C or more) of heat “dumped” to cool it to below ambient temperature so the heat from ambient air can be used to vaporise it again. A huge amount of heat/energy that has already been put into the refrigerant to achieve 80°C is available for use/heat recovery. This is the reason that the EscoPod utilises an economiser system and some of the benefits it delivers are:

• The economiser circuits are used to increase efficiency by delivering a percentage of the total heat output from a smaller, low power draw compressor using heat recovery from the high temperature liquid refrigerant as a source. It is more efficient and cost effective to use a smaller compressor, doing less work, to add to the heat output;

• Defrosting is a significant consumer of energy in any heat pump system, especially in a climate such as Ireland’s, where we have reasonably-high relative humidity (a cause of ice build-up when low ambient air temperatures prevail).

The EscoPod AZE/H defrost system takes energy from the high-pressure, high-temperature liquid refrigerant, enabling efficient defrosting while simultaneously providing heat to the heating circuit. Being able to defrost simultaneously also prevents large ice build-up in the first place;

• As well as using the economised mains heating circuit, the system can simultaneously provide heating for DHW/high-temperature sanitary water (up to 65°C) with no extra electricity consumption, using the sensible heat of the system;

• Finally, rather than cooling the ambient air, the system can also remove heat from a chilling (glycol) circuit, with no extra energy consumption. This allows clients to run a chiller system without any extra power consumption or equipment.

EscoPod features

• System uses highly-efficient low GWP, low toxicity and no ODP refrigerant R1234ze;

• Bespoke air source evaporator ensures the optimal quantity of heat is extracted from the air. The air source evaporators are sized to maximise the amount of heat transfer;

• Optimised defrost cycle management to significantly reduce defrost energy and ice buildup in the first instance;

• Variable speed fans on the evaporator draw in the required volumetric flow of air while minimising noise;

• Variable speed compressors allow for precise control over system operating conditions depending on ambient air temperature/conditions to maximise efficiency;

• Compressors are semi-hermetic allowing maintenance – which is more sustainable than replacement;

• High-capacity industrial compressor motors allow efficient operation at high discharge and high evaporation temperatures;

• Coalescent oil separator, minimal pressure drops and maximum oil recovery. Prevents oil foiling on heat exchangers, always ensuring maximum heat transfer efficiency even at part load;

• Electronically-controlled oil distribution between compressors ensures compressor longevity and maintains performance;

• Bespoke plate heat exchangers ensure optimal heat transfer for specified/ required conditions on site;

• Components and pipework layout optimised to minimise pressure drop in the system and to maximise efficiency.

Many awards for EscoPod

The EscoPod has been awarded several prestigious industry awards, including The Green Technology Award (Green Awards 2023) and the Best Innovative Product and the Overall Product of the Show Award at the SEAI Energy Show 2023. ActionZero CEO Denis Collins was also recently announced as a finalist in the 2023 Entrepreneur of the Year Awards.

On the commercial side, ActionZero is currently engaged in several highprofile projects, actively installing heat pump systems for healthcare, commercial and industrial clients on sites in both the UK and Ireland.

To support the ongoing development and expansion of its EscoPod product range, ActionZero opened an Irish manufacturing and research and development centre in Tralee in May 2022. From here, the company designs and manufactures the heat pumps before exporting them to clients internationally.

ActionZero works closely with consulting engineers and specifiers to support organisations in both the healthcare and commercial sectors to enable the successful deployment of its heat pump technology. Continued engagement and partnership with system designers and specifiers remains a key part of ActionZero’s strategy.

Prestigious industry award for Wilo

Wilo’s Smart Factory in Dortmund received the “Factory of the Year 2022” award in the “Excellent Transformation: Digitalisation” category at a ceremony in the Allianz Arena in Munch recently. The occasion was part of a twoday conference where Germany’s best manufacturing companies shared their success stories.

“We’re proud of our pioneering flagship factory,” said Georg Weber, a member of the Executive Board and CTO of the Wilo Group. “With a high level of digitalisation and a consistent focus on Industry 4.0 standards, we are ideally equipped to meet the major challenges of the future.”

Dr Mahmud Al-Haj Mustafa, Senior Vice President of Group Operations at Wilo, added: “This award once again highlights that we’re the digital pioneer within our industry. A shortage of specialists, digitalisation, sustainability … the challenges facing manufacturing companies today and in the future are huge. Exchanging ideas with other drivers of innovation, as we recently did in Munich, is therefore particularly useful.”

A keynote speech was delivered by Branko Calusic, Vice President of Operations in Dortmund, who is responsible for the Smart Factory at Wilo’s headquarters. He demonstrated the role of digital technologies at the

plant which was opened in 2019. For example, Wilo uses live dashboards that show the utilisation of individual production lines at any time. In addition, networked, driverless transport vehicles are used to automatically supply production workers with the right material at the right time.

“Digital transformation offers a wealth of new opportunities,” says Oliver Hermes, President & CEO of the Wilo Group. “I am therefore particularly pleased about this award. The fact that we, as a digital pioneer, were awarded in this category is proof of our ambition and our self-perception to develop future-proofed solutions for the challenges of our time.”

The “Factory of the Year” is one of the most prestigious and soughtafter industry awards in Europe. The competition has been in existence since 1992 and, over the years since then, approximately 2000 companies have taken part in the benchmark

competition. This year was Wilo’s first time entering the competition.

With the award, the jury recognised, among other things, the digitalisation and sustainability of Wilo’s Smart Factory and also found that Wilo’s hydrogen strategy was “remarkable”.

“Wilo can become a global player in the creation, storage, distribution and utilisation of hydrogen,” concludes Oliver Hermes. “We already have numerous products and solutions in our portfolio that can be used in the first stage, ie, generation and storage. These include reverse-running pumps for driving hydropower generators, along with pumps for cooling circuits in wind turbines through to rotor drive actuators for these turbines.

“As hydrogen makes its way to the end-user, there are further wideranging possibilities for using Wilo’s products, solutions and services, including areas such as fuel cell technology.”

Radiators that work well with heat pumps

The rise and rise of the heat pump is seeing the need for larger and higher-capacity radiators. Stelrad has responded to these needs by broadening its already massive range for its most popular radiators and the introduction of a wider range of vertical radiators.

Stelrad also meets the enhanced need for its K3 radiators – with three panels and three fins. These deliver 50% more heating capacity from a radiator with the same footprint as a K2 format radiator.

Low-temperature heating systems have understandably raised questions that installers and specifiers want answered. Can products used in conjunction with traditional boiler-driven heating systems be used with heat pumps? Is there anything that needs to be considered that’s taken for granted nowadays? The answer is of course yes. Specifiers and installers need to look closely at how to ensure that the heat generated is shared effectively in the

new home, or the existing home that is having its heating system upgraded. In new-build housing, using a heat pump-based solution is a relatively simple solution. The heating system can be designed into the home at the outset so the installer knows the parameters in which the heating system has to operate – the method of construction, the size of the rooms, the number, type and size of doors and windows – so the heat loss calculations can be done up front and radiators sized accordingly.

At the outset, the levels of insulation can be agreed that will provide the best support for any heating system chosen, whether radiators or underfloor heating.

The key to radiators operating well in any situation is to size them properly at the design stage. This involves accurately working out heat loss calculations to achieve the necessary number of BTUs required to provide comfort heating in each room, and selecting a radiator that can provide that level of heating.

Stelrad offers a simple-to-use and free radiator sizing and heat loss calculator, along with a Renewables Advice page on its website at Facts and helpful information are also shared through a free CPD that is also available on its website.

So, should radiators be excluded in favour of other alternatives as some are suggesting? The answer is a resounding no. Radiators are very much “fit for the future” but, as always, correct sizing will need to be undertaken to ensure that they keep the home warm and cosy. Can radiators work well with air source heat pumps? Very definitely yes, they can – and they already are in a host of installations across Ireland.

Hitachi’s Samurai M solves logistical challenges … and it is good for the planet

In Q4 2019, the World Green Building Council reported that building and construction were responsible for 39% of all global carbon emissions, with operational emissions from energy used to heat, cool and light buildings accounting for a total of 28%. The UKGBC found that 69% of operational emissions from the built environment were used in heating buildings which accounts for 10% of the total UK carbon emissions. With this as the backdrop, it is clear that the HVAC industry has a big part to play in driving down operational carbon emissions. Hitachi has been designing highly energyefficient equipment for years, making units compact for economy of transport and modular for ease of installation. The ultracompact R410A Samurai M chiller is no exception with a SEER of 4.5 (24HP), SCOP of 3.54 (50HP) and optional low noise level of 6 dB(A) average.

“All included” design as standard Perfect for the replacement market, Samurai M has a 2.7m2 footprint for 130kW of heating and, being “modular by design”, it is adaptable to the demands of the space. All models come fully loaded with a range of components as standard:

• Low leaving water temp kit;

• Master/slave mode;

• MODBUS/BACnet interfaces;

• Anti-corrosion protection of fins, flow and water filter;

• Onboard touch control operates up to 16 units in a cascade system.

Samurai M chillers feature two to four independent refrigerant circuits from 44kW to 254kW cooling. The automatic distribution of operation hours for the compressors

increases component durability and the modular design ensures continuous operation in the event of a single unit failing. It also limits site redundancy investment. But the key to equipment energy efficiency lies not just in the equipment itself, but in how it is set up, controlled and maintained. Controls are key With commissioning and set-up, it is important that building owners, operators or occupiers are involved in the control scheduling decisions. This ensures that equipment operations are tied to the business needs and the building’s requirement for heating, cooling and hot water delivery, and accounts for seasonal variations.

Often overlooked, controls are the key component that ensure a system’s efficiency, provide a comfortable room environment and prevent wasted energy.

Lower operating costs

For medium and large installations, a centralised control system like Hitachi’s CS-NET Manager can connect all heating, cooling and ventilation systems onto one touchscreen controller, enabling both onsite or remote control, monitoring and scheduling, and allowing changes to be made to ensure the optimal efficiency of the system.

Enabling this technology and commissioning it in the right way will lead to a better deployment of engineers, lower operating costs, a reduction in the operating carbon and reduced equipment downtime.

As demand for cooling and heating continues to grow, manufacturers will continue to invest in R&D to cut carbon emissions. However, everyone can do their bit now by ensuring that systems are correctly set up and that controllers are maximising energy and labour efficiencies.

Liz Finegan, ATC Dublin

Having being introduced to tapdancing at an early age, Liz Finegan from ATC was soon bitten by the performing bug and then very quickly graduated to competitive dancing.

As she grew up, she had a great deal of success, winning many trophies before standing back from competitions in her early teens. However, the pull of the stage was too strong and, through a friend, she started to dance with the famous Lorraine Barry in Dublin. Her objective at the time was to have some fun, benefit from the exercise, and enjoy the singing and dancing.

Her interest in variety shows was sparked by a chance meeting with people who were rehearsing for a show. She made further enquiries, and before she knew it, she had an audition and got a part in a group performing in

the Aer Lingus Variety Show at the Olympia Theatre. So began an enduring love-affair with musical and variety show performance.

She is currently a member of the Rush Musical Society and is invariably involved in one, if not two, shows per year. When in rehearsals, it is very intense with at least two practice sessions a week to begin with, and this increases as the opening night draws near. On top of that, there are the costume fittings, not to mention the various fund-raising initiatives, as this is amateur dramatics.

“At times it is very demanding on quite a number of fronts,” says Liz, “but

I love it. The excitement of performing, the buzz of the adrenalin rush when on stage, the crowd applauding and even the total exhaustion at the end of a run … I would not change it for the world.

“For me, being involved in musical theatre is like being part of an extended family. It is a community where everyone knows one another and, for the most part, are good friends. Outside of performing together we also socialise and go to see other groups performing.

“An added bonus is that my husband is also involved in variety shows and, I must confess, our happy lives together all began when we met when we were both performing in Chicago.”

ICE cool Purcell

Congratulations to John Purcell on his recent “Industry Contribution Award” at the ICE Awards. John is one of the “founding fathers” of Ireland’s building services industry and played a major role in steering its development over almost 50 years.

John, who joined Varming Mulcahy Reilly Associates in 1970 as a graduate, quickly progressed through the senior ranks, becoming CEO in 1996 and subsequently Chairman in 2006. In 2019 he stepped down as Chairman but still continues his involvement with the company as a consultant.

Congratulations to David and John Doherty on being the only father and son pairing ever to receive CISBE bronze medals for services to the Institution.

John received his some years back and David received his at a CIBSE-led industry event in the RDS Members Club recently.

Quite uniquely, John was on hand to make the presentation to David. Both are shown here proudly holding their medals.

Nailing colours to the mast

O’Callaghan Red has opened an office in the “Rebel County” which is located in the ultra-modern Navigation Square right in the heart of the city.

Director, Killian O’Neill, said: “We are fortunate to have talented and conscientious employees who care deeply about clients and the impact of their designs on the environment.

“This spirit resonates across our whole business and is reflected in the collaborative environment we have invested in for our diverse, growing and dedicated team in Cork.”

Chadwicks ‘Four Peaks’ for charity

A 17-strong team from Chadwicks Group took part in the recent Four Peaks Challenge with a view to raising €50,000 for five charities. The team navigated Slieve Donard in Co Down, Lugnaquilla in Co Wicklow, Carrauntoohil in Co Kerry and, finally, Mweelrea in Co Mayo. Separate hikes also took place over that weekend with 23 other staff members scaling one of the peaks.

Self Build Live

Great to see such a large turnout at the recent Self Build Live in Dublin. While for stand personnel it was either manic or slow – as is the nature of such events – the overall experience for exhibitors was very positive.

As Keith Scully (below) from Grant Engineering explained to me: “Apart from securing actual sales leads, the key objective is enduser engagement.

“The chance to explain the fundamentals of new technologies to consumers, and in particular heat pumps, is invaluable, For that alone the show is extremely worthwhile.”
