Ambition must reflect reality

In February of this year, the EU published a “detailed impact assessment on possible pathways to reach the agreed goal of making the EU climate neutral by 2050”. The term “detailed assessment” suggests a definitive outcome yet, it is immediately linked to “possible” pathways. Surely this is an oxymoron.

Possible suggests aspiration … dreams, hopes and even ambition. Not that there is anything wrong with that. In fact, it is very important to strive towards such goals. However, they must be realistic.

The EU already acknowledges that many countries (including Ireland) wont’ hit their 2030 targets. Nonetheless, it is still ploughing ahead with 2040, and even 2050, targets.

Of course there is no “silver bullet”, but setting goals based on insecure foundations is totally unsustainable. 18

While the entire building services engineering sector is rightly focussed on the goal of zero emission buildings, the invaluable – and indeed critical – role refrigeration engineers have to play is often underestimated. Martin O’Brien, President, Institute of Refrigeration Ireland (IRI), explains.


Key take-aways from recast EPBD

John Burgess, MEP Engineer, Energy Auditor and Energy Efficient Design Facilitator working in Arup’s award-winning Cork Office, highlights how key changes in the recently-recast EPBD will lead to significant changes in decarbonising new and existing buildings.

Reliable, economic, sustainable Wilo launches ‘energy solutions’ initiative

There are three major factors prompting more and more building owners to take serious measures to significantly improve their energy footprint. These are ambitious climate targets they have set themselves; EU regulations and guidelines; and what, in some cases, are drastic rises in energy costs.

“Wilo has a key role to play in resolving these challenges,” says Derek Elton, Managing Director of Wilo Ireland. “Our ‘energy solutions’ initiative encourages the proactive replacement of still-functioning, but uncontrolled, pumps with advanced Wilo high-efficiency pumps. Whether it is a public, commercial or industrial building, our expert technicians conduct a thorough plant analysis and then recommend the appropriate course of action to be taken.

“A considerable percentage of global energy consumption is attributed to electric pumps. However, we are very much aware of the enormous climate protection potential of modern pump technology and want to advance its widespread adoption across all applications. Our aim is to save 1.8 terawatt-hours of electricity a year through the use of highefficiency pumps.”

Wilo’s high-efficiency pumps are electronically controlled and adapt to the system’s actual requirements. A special drive, the permanent magnet motor, forms the technological basis of the energy-saving potential, and a pump of this kind consumes up to 80% less electricity than a comparable uncontrolled pump. For instance, up to 92,000 kilowatt-hours – or around €40,000 – can be saved over 15 years with the Wilo-Stratos MAXO, with the quick pay-back periods making the investment in switching to modern pumps very attractive.

This highly-efficient technology caters for all areas of building services, water management and industry. It surpassed Wilo’s goal of 1.8 terawatthours in 2022 (2023 figures not yet available) when it achieved global energy savings of 2.2 terawatt-hours. This figure also allows “avoided emissions” to be taken in to account. According to the Greenhouse Gas Protocol (GHG), these are emissions that do not even occur because a more efficient product has replaced a predecessor model. The positive result can be attributed to the current rising demand for sustainable, environment-friendly, efficient products.

Recent geopolitical events have also contributed to the increased demand for high-efficiency pumps in the OEM sector, especially among heat pump manufacturers. The Wilo-Para MAXO is the latest OEM product in the Wilo stable. Taken together, the hydraulics and motor achieve an energy efficiency index (EEI) of less than 0.2, a figure that even exceeds the EU regulations for energy-related products.

Ecopump flagship project Europump vision and priorities

As President of Europump, the European pump association, Luboš Michlík brings a wealth of experience and a clear vision for the future of the European pump industry. An experienced engineer specialising in sales and project management across the rotating machinery sector, he is committed to advancing the Europump mission of promoting excellence, innovation and sustainability within the European pump sector.

Under Michlík’s leadership, Europump is dedicated to enhancing collaboration between industry stakeholders and regulatory bodies to ensure the development and implementation of

robust standards and directives. The association remains actively engaged in important initiatives related to various applicable directives, including the EcoDesign Directive, the Energy Labelling Directive, the Machinery Directive, and the Drinking Water Directive. All of these will have a significant impact on the pump sector.

Another key topic of interest for both the Technical and Standards Commissions within Europump is the restriction in use of PFAS materials (per- and polyfluoroalkyl substances). Given their presence in a wide variety of products associated with pump installations –such as sealings, bearings, cable sheaths, coatings, pump inserts and membranes – all restrictions must be fully considered, and possible alternatives identified, before any changes come into force.

Luboš Michlík, President of Europump, has held various key positions with Czech Republic pump manufacturer, SIGMA Group, best known for its mid-size, heavy and one-off specialised pumps, and pumping sets for a wide range of industrial applications. He currently holds the position of CEO and Member of the Board of Directors, with responsibility for corporate structure, managing overall business operations, and setting the company’s strategic direction.

“As President of Europump, my primary focus is to champion the interests of the European pump industry and drive positive change that benefits both our members and society as a whole,” says Michlík. “ We are committed to upholding the highest standards of quality, safety and environmental responsibility across all aspects of the industry.”

New website

To better communicate with its members, and the industry at large, Europump has unveiled a new website ( designed to provide members and stakeholders with easy access to information, resources and industry updates. The website serves as a central hub for news, publications, technical guidance and events, reinforcing Europump’s commitment to transparency and communication.

In line with its commitment to fostering collaboration and knowledge exchange,

Building Services Engineering l March/April 2024 13

Europump will stage its upcoming Annual Meeting in Windsor, UK, from 22 to 24 May this year. Hosted by the British Pump Manufacturers’ Association (BPMA), the event will bring together industry leaders, experts and stakeholders to discuss key challenges, opportunities and emerging trends shaping the future of the European pump industry.

Further information on the Annual Meeting, including details on the full programme of talks and presentations, can be found at the dedicated website:

“I invite all our members and partners to join us for the Europump Annual Meeting in Windsor, where we will engage in constructive dialogue and exchange ideas to drive innovation and progress within our industry,” adds Michlík. “A great deal of effort has been put in to producing an informative and productive series of meetings, all of which will focus on the key issues facing the pump sector, now and into the future.

“Our commission meetings will deliver important updates on the activities of the various working groups, and will be underpinned by a range of highlyappropriate talks and presentations, before culminating with our General Assembly. A wonderful social programme is also planned, taking full advantage of the superb location, making this a must-attend event.”

As Europump continues its complex work under Michlík’s leadership, assisted by the Chairs and members of the various commissions – Standards, Technical, Marketing and SME – the association remains steadfast in its commitment to advancing the interests and priorities of the European pump industry, while promoting sustainability, innovation, and excellence across all aspects of its work.

Ecopump flagship project

Ecopump is Europump’s flagship project, embodying Europump’s energy commitment. The Europump Council endorsed the Ecopump initiative as far back as 2004 and it now forms the cornerstone of the European pump sector’s energy and environmental policy. Ecopump is built around three key pillars – Product, Extended Product and Systems. The underlying objective is to ensure that:

• The liquid end of products meets minimum efficiency levels;

• Product savings are optimised through the extended product approach and controls;

• The installed base is investigated to ensure that efficient products are installed into efficient systems.

Since the inception of Ecopump, Europump has built an enviable reputation for its professional integrity across many institutions including the European Commission, national governments, NGOs, user groups and many other stakeholders. It instigated the extended product approach, increasing product saving opportunities tenfold over and above those achievable from product legislation alone.

As an industry which is a significant consumer of electromotive power, it is the role of Europump through its Council to:

• Protect the interests of European pump manufacturers, large and small, in the face of legislative programmes;

• Look after the interests of pump users, who are the customers;

• Ensure that all stakeholders consult widely, use proper channels, and carry out due diligence in the pursuit of the legislative process;

• Work directly with all stakeholders, including (where appropriate) suppliers, customers, NGOs and governmental departments;

• Ensure that all options are considered, not just the process of legislation, but other methodologies such as voluntary measures or labelling.

Ecopump remains a fluid initiative within Europump. This is important as, for example, it is the only mechanical industry group engaged in tracking – with the consultants to the European Commission – the product environmental footprint initiative. This is despite the fact that it is acknowledged that pump energy is predominantly consumed during the use phase, further confirming its commitment to environmental integrity.

Maintaining health and safety standards and regulatory compliance for water supply and pressure are complex areas that require ongoing attention. There is also a pressing need to reduce the environmental impact of buildings, by cutting carbon emissions and water and energy consumption.

In Ireland, the Climate Action & Low Carbon Development (Amendment) Act (2021) set a legally-binding target of a 51% reduction in national CO₂eq emissions by 2030, and an overall target of a climate neutral economy by 2050.

The new hydrovar X intelligent variablespeed pump drive can cut the motor power of pumps by up to 70%.

Older pumps typically run at a fixed speed, regardless of demand. Retrofitting with variable-speed drives enables the system to adjust to usage curves.

Xylem’s hydrovar intelligent variable speed pump controller, named Best Energy Efficient Product at the Sustainable Energy Authority of Ireland (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 necessary energy.

hydrovar® X

The newest model hydrovar X is an intelligent variable-speed pump drive, with the highest efficiency IE5 motors, that can cut the motor power of pumps by up to 70%. This will have an immediate impact on the energy consumption of large commercial buildings where water demand can fluctuate throughout the day.

Integrated functions provide protection for the pump and motor, and improve the quality of energy from the grid. Built-in application software makes commissioning and operation simple, enabling virtually any configuration of pumps.

For buildings, a roadmap from the Irish Green Building Council (IGBC) sets out plans to decarbonise Ireland’s built environment across its whole life-cycle by 2050. With the construction and built environment sectors accounting for 37% of Ireland’s carbon emissions, according to the IGBC, the transformation will be challenging. However, it also presents opportunities to innovate, improve performance and make long-term cost savings.

For the critical areas of water supply and pressure boosting, Xylem’s latest technology can support water efficiency and the move to decarbonisation, maintain compliance and safety standards, while, at the same time, delivering high performance and cost efficiencies.

Efficient systems

Supplying water to large buildings is energyintensive, due to the level of pumping that is required – energy is the largest cost of running any pump. System efficiency is key to minimising cost and environmental footprint. Years of experience have taught Xylem that a lot of pump systems are

oversized for the application. Running and maintaining an unnecessarily large system wastes energy and money.

One way to significantly reduce the energy consumption of pumped systems is by switching to variable speed technology.

This means excellent energy saving from a compact, easy-to-use solution suited to nearly any application. hydrovar X’s combination of motors, variable speed drives and pumps can provide great performance, maximum savings, and a rapid return on investment.

By prioritising efficiency and innovation, we can create a more resilient, sustainable future in water management.

Refrigeration and air conditioning IRI champions RAC interests in face of f-gas and related challenges

While the entire building services engineering sector is rightly focussed on the goal of zero emission buildings, the invaluable – and indeed critical – role refrigeration engineers have to play is very often underestimated. The stark reality of rising temperatures means that cooling is now more essential than ever, and that it must be an integral part of all future infrastructure.

That realisation is perhaps best championed by the various professional refrigeration bodies throughout the world and, here in Ireland, by the Institute of Refrigeration Ireland (IRI), which is affiliated to a number of international bodies.

IRI has taken the primary leadership role in refrigeration, driving the pursuit of excellence in both the quality of refrigeration and air conditioning products supplied, and the quality of installed systems. It has established and maintains high standards of education, training and conduct, while also working closely with other industry stakeholders, including government departments, state agencies, universities and professional bodies.

Building Services Engineering recently spoke with Martin O’Brien (pictured), the newly-elected President of IRI,

who outlined some of the highlights from last year’s revision of the F-gas Regulation, the challenges posed by the rapid phase-down of HFCs, and the transition to C02 (carbon dioxide) and R290/R600 (flammables).

According to Martin, the most commonly used f-gases, representing around 90% of f-gas emissions, will be reduced by 95% by 2030 compared to 2015, going down to zero by 2050. This represents the world’s first total HFC phase out. The production of HFCs, in terms of production rights allocated by the Commission, will be phased down to a minimum (15%) as of 2036. Both production and consumption will be phased down based on a “tight schedule of decreasing quota allocation.” The feasibility of the phase-out of the consumption of HFCs, and the need for HFCs in sectors where they are still used, will be reviewed in 2040. This review will take account of technological developments and the availability of alternatives to HFCs for the relevant applications.

Impact on product suppliers

A full market ban will be placed on several categories of products and equipment containing HFCs, including certain domestic refrigerators, chillers, foams and aerosols. Some deadlines have been brought forward, with others extended to products that use f-gases with a lesser GWP. Exemptions from

18 Building Services Engineering l March/April 2024


the ban are provided if there are safety concerns.

A full ban has been introduced on small (less than12kW) monobloc heat pumps and air conditioning equipment that contain f-gases with a GWP of at least 150. This will take effect in 2027 with a complete phase out in 2032. With regard to split air conditioning and heat pumps containing f-gases, there will be a full ban starting in 2035, with earlier deadlines for certain types of split systems with higher GWP gases.

The 2023 agreement also includes the possible release of a limited number of additional quotas for heat pumps if the proposed bans were to endanger realisation of the heat pump deployment target required under REPowerEU. How the Commission intends to manage the release of these additional quotas is unknown. Indeed, it may end up being too late to repair the damage that will be caused to the domestic and wider heat pump industry.

Impact on repair and servicing

There is also a ban on some equipment needed to repair and service existing equipment. From 2025, servicing equipment for refrigeration equipment that uses f-gases with high global warming potential will be banned unless the gases are reclaimed or recycled, in which case they benefit from an exemption until

2030. A similar ban has been introduced for servicing equipment for air conditioning and heat pump equipment for 2026, with an exemption for reclaimed or recycled gases until 2032.

Impact on the price of f-gases

Starting in 2025, the HFC quota that the Commission allocates every year will be sold for €3 per metric ton of CO2e, adjustable for inflation. Part of the revenue will be used to cover the administrative costs of the implementation of the F-gas Regulation, and the rest will go to the general EU budget. This will have a serious impact on the €/kg price of f-gases to the end user.

Russell Patten, Director General of the European Partnership for Energy and the Environment (EPEE), said: “We believe this agreement will be challenging for the sector to implement given certain unclear provisions linked to the bans.”

Impact on training

The impending changes also impact strongly on training, and the lack of facilities in Ireland to deal with these refrigerants. The current Refrigeration Curriculum from 2006 (Version 2.2) does not deal with these alternative refrigerants.

“Nonetheless”, says Martin O’Brien, “there are now positive moves afoot to address this challenge. The IRI is currently engaging with other stakeholders, such

as SOLAS and the National Apprenticeship Office, on the training and education front. Through soon-to-be established technical working groups, the objective is for us to provide technical knowledge, guidance and proposals that will result in the long-overdue curriculum review.

Impact on contractors/installers

“Related to this is the need to highlight the importance of contractor involvement in the IRI as craft-based apprenticeships are being rapidly transitioned into the new, single apprenticeship, system which will involve a consortium approach for craft-based apprenticeships from September of this year. This imminent change in apprenticeship delivery will affect all contractors in the refrigeration and air conditioning sector. We in IRI extend an invitation to all contractors/ installers to join with us in establishing a consortium to identify the challenges they face, and to devise a solution that can be presented to all the relevant authorities involved.

“Looking to the immediate, shortand indeed long-term future, there is no denying the massive challenge facing the refrigeration and air conditioning industry. However, on the plus side, the IRI is the perfect vehicle to represent all sector interests in a cohesive, allindustry manner. Working together we can make a positive difference.”

Building Services Engineering l March/April 2024 19
most commonly used f-gases, representing around 90% of f-gas emissions, will be reduced by 95% by 2030 compared to 2015, going down to zero by 2050.

Unitherm Heating Systems Training Academy and SEAI-accredited heat pump course

Unitherm Heating Systems recently marked a major milestone in the company’s continuing development with the introduction of an SEAIaccredited Certificate in Heat Pump Installation, Commissioning, Maintenance and Servicing, and the opening of its new Training Academy at the company’s premises in Ballybane, Co Galway.

Hildegarde Naughton, Minister of State, officially opened the Training Academy in the presence of Oliver Mulryan, Head of Department, ATU; Graham Heaslip, Head of School of Engineering, ATU; Brian McIntyre, Programme Manager, SEAI and

Sophie Long, Bita Ireland West Chapter Vice-Chair.

Deputy Naughton, said: “This is exactly what we’re looking for at government level. Here you have industry and academia working together to ensure the graduates we are producing will have sustainable jobs into the future, while also helping to meet our need to reduce carbon emissions.”

Congratulations from SEAI Brian Mcintyre, Programme Manager, SEAI, said: “Congratulations to Unitherm and ATU for bringing together this fantastic course. A lot of work I do is dealing with industry

and trying to drive the standards to meet our decarbonisation targets. We have 400,000 heat pumps to retrofit by 2030. More importantly, that starts with having people on the ground who can install such quality installations.”

Shane Kelly, Director, Unitherm Heating Systems, said: “The private sector has a really important role to play in moving the decarbonisation effort forward and this is the reason why this collaborative heat pump training programme is so important, as it will help address the immediate and future skills shortage in the national economy.”

Most comprehensive heat pump course available

Developed in collaboration with Atlantic Technological Universities’ (ATU) Department of Mechanical and Industrial Engineering, this part-time programme allows participants to engage in 13 immersive days of hands-on training, spread over 13 weeks, with sessions held weekly.

The installers’ portion of the training is aligned to the National Standard Authority of Ireland’s (NSAI) published National Standard Recommendation for the Design and Installation of Heat Pumps in Homes – S.R. 50-4:2021.

With a focus on heat pump technologies, this programme has four times the amount of material compared to other courses, and is a rallying cry to address the urgent need for skilled labour in the field. It offers participants a transformative journey that equips them with vital skills, and champions a sustainable future.

The programme is run bi-annually and is unique in that a large part is aimed at maintenance and servicing. It consists of four hours theory in ATU’s Galway city campus, followed by four hours immersive practical training in Unitherm Heating Systems’ new state-of-the-art training facility in Ballybane. Here Derek Haynes, Academy Technical Director, instructs the students on the installation, commissioning and maintenance of heat pumps, and on the systems they are connected to.

“People are aware that the EU Energy Performance of

Buildings Directive [EPBD] requires zero emissions from fossil fuels for all new buildings by 2030, the displacement of fossil fuel boilers in all buildings by 2040, and net zero greenhouse gas emissions by 2050,” said Dr Oliver Mulryan, Head of the Department of Mechanical and Industrial Engineering, ATU. “I believe that this collaborative partnership will be mutually beneficial as renewable technologies evolve and their adoption grows. We congratulate all the graduates and I thank my colleagues John Scahill, Jimmy Fahy and all in the Digital Academy for the Sustainable Built Environment for co-funding this programme.”

The first group of 18 graduates began the programme in September, 2023, and a graduation ceremony was held on the recent official opening day to recognise their achievements. A second cohort is currently in training and will complete the course by this coming June. Geographically, it is the only such offering in the west and northwest region, and graduates of the programme are recognised as having met SEAI’s entry criteria for registration as a renewable heat pump energy installer.

€1 million retrofitting support

New ‘Warm Home Hub’ for Galway’s westside

Residents in Galway City’s Westside area now have access to a ‘“one-stop-shop“ to help them retrofit their homes, after the Northern and Western Regional Assembly (NWRA) and Galway City Council secured a €1m grant from the EU Net Zero Cities Programme.

A portion of the €1m funding from the Net Zero Cities programme will also be used to provide training courses in retrofitting for students, unemployed citizens, women and people with special needs in the region with the aim of helping them to upskill and secure “green jobs”.

The NWRA and Galway City Council jointly applied to the Net Zero Cities Programme with the specific aim of

enhancing the level of retrofitting across the Westside, an area of Galway City which is classified as the Galway City Decarbonisation Zone, due to its above-average number of high-energy users and energy inefficient buildings, as well as its potential for increasing green spaces and improving air quality.

Among other key initiatives to tackle emissions in the Westside is the creation of the “Warm Home Hub Westside”. The hub will provide advice to energy-inefficient households on how to retrofit through information sessions and consultations with contractors, and will be managed by the Galway Energy Cooperative.

In addition, the Net Zero Cities Programme will also support the following initiatives:

• University of Galway, in consultation

with Mayo, Sligo and Leitrim Education and Training Board (MSLETB), and the Atlantic Technological University (ATU), will develop a “Retrofit Accelerator Training Programme”. The programme is set to incentivise 60 personnel to undertake retrofitting training, to improve existing retrofit courses, and to ultimately develop guidelines for contractors to monitor the performance of retrofits;

• Various public and private sector partners will collectively form a steering group to identify challenges associated with retrofitting in the Galway City Decarbonisation Zone and fund solutions to help overcome these challenges to improving energy efficiency in the area;

• The development of a report that can show what was learned during this project so that the information can be disseminated to interested parties, with the aim of potentially replicating the work in all regions across Ireland.

Through these initiatives, the Net Zero Cities Programme will aim to support Galway City Council’s overall goal of reducing greenhouse gas emissions by 7% per annum in the Decarbonisation Zone, leading to a 51% overall reduction in line with the targets set out in the Climate Action Plan 2023.

Kieran Cunnane from Galway Energy Cooperative said: “There are many advantages to retrofitting that go beyond cost savings, including improved health and comfort, and a positive contribution to an important climate and environmentally-friendly scheme. As for the cost savings, the payback time for improving home energy is often shorter than many people realise, and grants at the moment are quite generous.”

Best in class product Wavin AS+ means reduced noise

Peace and quiet for a building’s occupants generally means no noise from neighbours or from external sources such as traffic. But it also means having no disruption from internal noise from the water pipe system or rattling water pipes. This is particularly important for those in co-living spaces, like apartment blocks, where plumbing systems are in use at various times during the day and night, leading to potential disruption and irritation for multiple residents.

According to CSO figures, in 2023 there were 11,642 apartments built in Ireland, a 28% increase on the previous year and more than the 2020 and 2021 totals

combined. With more occupants now moving into apartments, standards in these apartments require best-of-class fittings and sound insulation.

Upon launching the latest “Design Standards” for new apartments in December 2020, the Minister for Housing, Darragh O’Brien, TD, said: “Apartment development has a key role to play in the future sustainable growth of our urban areas, and in particular our cities. Greater availability and choice of well-located apartment development, together with enhanced affordability, will help encourage a move towards apartment living.”

Noisy pipes are a real nuisance and a common occurrence, especially in older homes and apartments. They also conjure up costly repairs and create excessive noise pollution.

One approach in new or older builds can be the use of products such as the

Wavin AS+, an ideal solution for tackling noise pollution in multi-occupancy developments, not only in apartments but also in hotels, hospitals, nursing homes, libraries and offices. It is manufactured using mineral reinforced polypropylene material and is available in diameters of 110mm, 160mm and 200mm respectively. The low-noise, acoustic pipes and fittings have thicker walls and are made from dense materials which prevent noise from escaping.

Wavin is well known as the world leader in plastic pipe systems for residential, nonresidential and civil engineering projects. Its innovative Wavin AS+ and bracket system provides a comprehensive solution for controlling noise levels. It offers some of the most impressive reductions in wastewater noise available in the market. With the Wavin AS+ bracketing system, a Db rating of less than 10Db can be achieved (Fraunhofer Institute of Building Physics test report 2019). The system outperforms all other systems on the market.

The high-quality nature of the material, and specially-developed sound-absorbing brackets, are perfect for small and large installations. This premium low-noise drainage system ticks all the boxes of noise reduction.

The Wavin BIM Revit package for Wavin AS+ (free to download) with integrated intelligence, facilitates fast and efficient design, providing 100% accurate representation of the way the piping system will be installed, along with a fully-integrated bill of materials for accurate costing and minimising wastage.

Combining the new innovation of Wavin AS+ with a considered approach to the layout of the whole system, means that specifiers ensure that projects are able to meet current acoustic regulations and client requirements from the outset.

The Wavin SoundCheck tool, available on the Wavin Website, provides the support to accurately predict the noise levels based on individual parameters of any Wavin AS+ installation. This tool has been developed by a specialist acoustic engineering company and measures more than ten variables covering both airborne and structure-borne sound.

Haier by Absol

Something new and innovative from traditional channels

Absol Renewable Energy has formed a strategic partnership with Haier for the distribution in Ireland of the expansive Haier portfolio of HVAC products and systems, which includes a wide range of sustainable heating and green energy solutions.

Led by the well-known Macartan McCague, Absol is a newly-formed entity combining 45 years of industry knowledge and experience. This new venture aims to provide an innovative approach to the distribution of heating and new energy products to the Irish market by using existing traditional channels.

“By partnering with one of the world’s leading HVAC manufacturers in Haier” says Macartan, “the opportunities to realise something new and innovative can become a reality when you consider the recent growth that Haier has experienced throughout Europe, and which we now intend to emulate in Ireland.

“Haier is all about creating smart communities and using smart technologies and the Internet of Things (IoT) to drive the efficient use of energy, especially from renewable sources which can be irregular. This is integral to all Haier products and systems and was a critical factor in our decision to join forces with the company.”

There are further synergies in the new distribution agreement in that Richard Sherlock is the European A2W and Heat Pump Product Leader for Haier. Richard has an equally-impressive cv in the sector in Ireland, and in fact, has worked with Macartan on many projects and occasions down through the years. They will now work closely together to drive this new initiative.

Given the vast scope and extent of the Haier portfolio – the full range features heat pumps, cooling, PV, battery storage, heating and water heating – the roll-out by Absol Renewable Energy will be gradual and strategic. Some of the initial products to be released are featured here.

About Haier

The Haier Group was established in 1984 by Zhang Rumin who centred the business around the RenDanHeYi philosophy. One of the key features of this philosophy is being “zero-distance” from trading partners. Haier aims to provide outstanding commitment and value to its partners and end customers, and to keep them at the forefront of developments with cutting-edge, innovative products and solutions.

Ireland has now been added to this network with the appointment of Absol Renewable Energy.

Macartan McCague who heads up Absol Renewable Energy.

Switching to R290

R290 is seen as the long-term, environment-friendly refrigerant option as it reduces the fluid load by 60%, which further reduces its carbon footprint. While R32 is a widely-utilised refrigerant, R290 is a more sustainable solution and hence its use in the new Haier air to water heat pump monobloc range.

The use of R290 leads to high energy savings while contributing to a more sustainable and greener planet. Due to the thermodynamic properties and its high performance, electricity consumption will be lower and there is a direct reduction of electricity costs for end-users.

Other features and benefits of the new Haier monobloc range include: Boiler alter native: An excellent alternative to a traditional boiler, it offers fast heating for domestic hot water – the water temperature can reach 80°C very quickly;

Low noise: Low sound level, down to 54dB(A) for the 4kW version;

Wide range of operation: The unit can be used normally and efficiently, even during extremely cold weather, down to -28°C.

M7/M8 heat pump water heater

The new Haier M7/M8 heat pump, water heating range uses environment-friendly R290 refrigerant gas with a global warming potential (GWP) of 3. With easy installation, high functionality and affordable pricing, these highly-efficient water heaters are suitable for cost and efficiency-based mass adoption. The units can produce 65ºC from compressor only, and do not need electrical assistance for legionella cycle or any normal use. The saleability and scalability is further underpinned by the breath of offering – full heat pump from 80-litre capacity up to 250-litre capacity.

Article 4: Scaling up

Need for task and impact-based learning

Scaling up the training process with task and impact-based learning (TIBL) creates a more agile and responsive system, and creates a dynamic capacity to deliver the skills for a sustainable sector. Task-based learning involves real-world tasks that learners must complete to develop their skills. Coupling this with an impact-based learning approach helps learners to understand the real-world impact of their work, and provides them with a sense of purpose, writes Paul McCormack (right), Belfast Met Innovation Manager and ARISE Programme Manager.

ATIBL approach that utilises the full potential of technology-enabled learning opens the training to be accessed by all. Leveraging digital tools such as e-learning platforms, virtual reality and augmented reality provides learners with a more engaging and interactive learning experience, and helps them apply their learning in practical situations. Using digitalisation in this way helps develop a culture of continuous learning. Additionally, providing access to ongoing development opportunities such as workshops, conferences and other training programs also helps.

Collaboration with employers, industry experts and other stakeholders is essential. Engaging with stakeholders can help identify emerging trends and technologies, and ensure that the skills system is flexible enough to adapt to changing needs.

Data can provide valuable insights into the skills gaps that exist within the sector and help inform the development of

training programs that address those gaps. Analysing data can also help identify trends in job demand, skill requirements and training needs.

Inclusive adult participation

Inclusive adult participation and life-long learning will reduce the skills imbalance. Therefore, the training interface must be accessible to all learners, regardless of their background or circumstances. This requires a variety of formats, including online, face-to-face and blended learning options. It is vital that the process removes barriers to engagement.

Inclusive adult participation in life-long learning may be hindered by many barriers, such as cost, time and access to training. Addressing these barriers through initiatives such as funding support, flexible learning options and community-based training programs can help. Employers can also support life-long learning by helping to provide the opportunities for training and development, and by recognising the value of ongoing learning.

Traditional systems need to be invested in to help promote digital competencies as the skills process must understand the impact of technology and the advantages that it can deliver. To develop digital competencies, workers would need to have a strong foundation in digital literacy. This means having the ability to use digital tools and technologies effectively, and being able to evaluate information critically and responsibly.

This will create a more effective and sustainable skills system that benefits workers and the wider society.

Overall, creating a skills system that is responsive to current and future needs requires collaboration with industry stakeholders, data-driven decisionmaking, emphasis on practical skills development, technology-enabled learning, and a culture of continuous learning. By adopting these strategies, the construction industry can build a more skilled and adaptable workforce that is better equipped to meet the demands of the future.

Lighting – classification of luminaires

Mandatory EPREL lighting registration

LAI’s EPREL Committee recently participated in a half-day EPREL Workshop hosted by the Market Surveillance Authority (MSA) within SEAI. As the MSA in Ireland, SEAI’s role is to verify whether products sold in the EU follow the requirements laid out in EU regulations, including the European Product Registry for Energy Labels (EPREL).

Under EPREL, suppliers (manufacturers or their authorised representatives, and importers) are legally required to register any models of products placed on the EU market that are subject to EU energy labelling requirements. Among the many product groups covered by this mandatory requirement is lighting.

Confusing and challenging

However, some LAI members found the EPREL registration process confusing and challenging, and as a result of this, engagement between LAI and SEAI led to the recent workshop hosted by the Market Surveillance Authority (MSA) in SEAI’s headquarters in Dublin. It was a most productive meeting with honest engagement, the critical outcome being that the main problem concerns the interpretation of some of the terminology used, most specifically


what constitutes a “light source” and a “containing product”. This now sets the basis for future meetings and discussions on which Building Services Engineering will continue to report.

LightingEurope is the voice of the lighting industry and is committed to promoting efficient lighting that benefits human comfort, safety and wellbeing, as well as the environment. It is based in Brussels and represents 31 companies and national associations, including Lighting Association Ireland (LAI). Together, these members account for over 1,000 European companies, the majority of which are small or mediumsized. They represent a total European workforce of over 100,000 people and an annual turnover exceeding €20 billion.

LightingEurope and EU Taxonomy

The EU Taxonomy is a green classification system that translates the EU’s climate and environmental objectives into criteria for specific economic activities for investment purposes. In its current version, the Delegated Act of the EU Taxonomy –which establishes the Technical Screening Criteria (TSC) for determining when an economic activity qualifies as contributing substantially to climate change mitigation or climate change adaptation – covers manufacturing of lighting products in activity 3.5. –Manufacture of Energy Efficiency Equipment for Buildings.

Specifically, in this section the manufacture of light sources, and of presence and daylight controls for lighting systems, are expressly mentioned among the economic activities eligible for Taxonomy. The current wording in the Regulation, as described above, does not provide full clarity on the classification of the manufacturing of all lighting products in the EU Taxonomy for climate change mitigation and adaptation purposes. This has created some uncertainty in the market.

LightingEurope believes that it would be beneficial if the manufacture of luminaires as a whole would also be explicitly mentioned as an enabling activity for Taxonomy climate change mitigation and adaptation, with relevant and specific Technical Screening Criteria. For this particular reason, LightingEurope is currently working to help clarify the wording of the activity definitions, including the Technical Screening Criteria, in view of a possible future amendment of the legislative act.

Light+Building Show 2024 – Review Lighting sets stage for sustainability and efficiency

The backdrop to the recent Light + Building show in Frankfurt is that modern buildings are intelligent, connected and, as a result, save energy. In combination with alternative energy sources and efficient lighting solutions, emissions in the building sector can be significantly reduced. At Light + Building, over 2,000 exhibitors showcased how they can help bring this about to 151,000 visitors.

“The atmosphere at the exhibitors’ booths, in the halls and throughout the exhibition grounds was simply fantastic”, said Wolfgang Marzin, President and CEO of Messe Frankfurt.

“We are extremely pleased that so many exhibitors and visitors, as well as our long-standing partners, have continued the success story of the world’s leading trade fair for lighting

and all other building services technologies in 2024.

“With the switch to renewable energy sources, greater efficiency and sustainability in buildings, the industry has key goals on its agenda. That is why it utilises the Light + Building platform to present and discover innovations.”

Key topics are the electrification

and digitalisation of homes and buildings in order to reduce emissions and reuse raw materials. At Light + Building, the industry presented the digital and electrotechnical infrastructure for this and, on that basis, showcased solutions for dynamic power control, energy storage systems and applications for connected security.

A developing area is in the range of e-mobility and charging infrastructure, as well as innovations and products for decentralised energy supply systems and components.

Light plays an important role in the architecture of tomorrow. At Light + Building, 65% of exhibitors belonged to this sector. They presented highquality lighting solutions for indoor and outdoor areas, as well as dynamic room concepts. Modern LED installations ensure contemporary efficiency and either blend harmoniously into the architecture or emphasise the design elements. Lighting provides maximum visual comfort in all living and working environments. Thanks to the materials used, acoustic lighting combines a pleasant lighting atmosphere with sound-absorbing functions.

Lighting plays an important role in sustainability and circularity.

Building Services Engineering l March/April 2024 37

Sustainability plays an essential role in both the materials used and the manufacturing processes, and many manufacturers design luminaires in a way that the raw materials used can be recycled at the end of their useful lifecycle.

Power Creator Days

The leading content creators in lighting and building services technology gathered for the Power Creator Days. In addition to live podcasts, expert talks and case studies, visitors had the chance to “pedal” for a good cause and work together towards a high energy target. A total of 1,510 minutes were cycled on the six fitness bikes. The sponsors will convert the result into a cash donation for the Leberecht Foundation, which Messe Frankfurt will double.

Sector coupling

Alexander Neuhäuser, General Manager ZVEH (Central Association of the German Electrical and Information Technology Trades), said: “Light + Building demonstrates how sector coupling can succeed through the necessary connectivity. The electrical trades integrate photovoltaics, storage, electromobility and heat pumps. They show how the energy industry

requirements for controllable consumption devices (SteuVE) can be met and thus take account of the current transformation process.

“The traditional partners’ evening was also a success, bringing together the partners of the electrical trades and the industry leaders. Young people again took the opportunity to visit the E-House and the Workshop Street, and to see what is feasible with smart and intelligently-connected building automation.”

Well-designed climate protection

Wolfgang Weber, CEO, ZVEI (Electro and Digital Industry Association), said: “In the context of climate goals and the economic situation of urgently creating more affordable living space, technologies are increasingly coming into focus. The exhibiting companies at Light + Building have impressively demonstrated how easily well-designed climate protection can lead to even greater economic efficiency in the operation of houses, buildings and entire neighbourhoods.

“This requires the right solutions, especially from the electrical and digital industry, such as heat pumps, controllable lighting, charging points and an energy management system. This is relevant, not just in Europe, but worldwide.”

While the products and services showcased at the recent SEAI Energy Show covered the entire building services engineering spectrum, heat pumps and solar panels were very much to the fore. This is hardly surprising as it reflects Ireland’s drive for sustainable heating systems and the industry’s response with innovative solutions to achieve that goal.

Footfall was similar to last year but the quality of those coming through the doors was of a very high calibre and, in the main, represented senior personnel and key decision-makers. In addition, the standard of the stand displays reflected a sense of confidence, and indeed intent, on the part of exhibitors. It was obvious that a great deal of thought had gone in to the product presentations, while all were well manned with expert personnel.


Heat pumps and solar panels to the fore

The SEAI Energy Show is much more that an exhibition. There is also an extensive programme of technical seminars, Energy Theatre presentations, the Product of the Show Awards and the Retrofit Demonstration Area.

The latter perhaps best sums up the nature and intent of the entire event. It involves a running series of live, inter-active, practical demonstrations that encapsulate the full spectrum of a building. It runs in sequence, beginning with a fabric-first insulation emphasis and then taking in everything from an airtight test through to ventilation, solar panels and heat pumps.

While the challenge facing the sector is still quite daunting, the SEAI Energy Show demonstrated that product and solutions providers have the armoury to meet it. The bigger challenge lies in devising strategies that can successfully harness those resources.

Over the past year, global temperatures have soared to record highs, surpassing the pre-industrial benchmark by 1.5ºC for the first time. As the world grapples with the climate emergency, the European Commission is steadfast in its pursuit of climate neutrality by 2050.

In February of this year, the Commission communicated on a 2040 climate target, and also introduced the EU Industrial Carbon Management Strategy. This new target is quite ambitious, setting a 90% net reduction in all greenhouse gas (GHG) emissions compared to 1990 levels.

The European Federation of Consulting Engineering Associations (EFCA) endorses the robust EU climate agenda but it emphasises that it cannot be achieved without well-functioning infrastructure, faster progress in carbon capture and utilisation/storage (CCU/S) technologies, and the availability of increasinglyscarce raw materials. In this article, Franziska Mohr, EFCA’s Policy and Communication Adviser, explains the consulting engineering community’s fundamental contribution to achieving the EU’s climate objectives.

Bridge to a greener Europe

Bridges washed away by raging floods, devastated river banks, roads with

giant holes – infrastructure – both manmade and nature’s own, is often no match for a climate disaster. Without it, society simply cannot function and the economic consequences of interruptions to both basic services and industrial production can be severe. Therefore, alongside protecting human life and livelihoods, we must protect existing infrastructure, making it more resilient, and design future infrastructure with climate risks accurately calculated from the beginning.

Sustainable and resilient infrastructure helps to reduce emissions as well as improve our lives by making our daily commutes more convenient. The impact on economic competitiveness of wellfunctioning and critical infrastructure is less noticed, but when infrastructure decays or collapses, the impact is felt immediately. The same applirs to environmental impact, hence the need to prioritise decarbonisation in infrastructure projects and enhance climate resilience in transportation, energy and urban development.

However, successful decarbonisation of EU industry is dependent on the availability of essential raw materials. The alarming lack and increasing cost of these is a very serious threat to EU competitiveness. In the early years of this decade, conflicts beyond our

borders have affected the availability of construction materials like cement and ceramics within Europe. This is ratcheting up the cost of energy-efficient renovations and green infrastructure. Therefore, increased research and development in alternative construction materials that could potentially supplement critical raw materials, thus mitigating dependency risks, is now urgently needed.

Neglecting infrastructure in the past has caught up with us and it is time to act, to prevent even worse economic, societal and environmental consequences in the future. Under the banner Sustainable Infrastructure: Bridge to a Greener Europe, EFCA places infrastructure development at the forefront of its policy agenda in its manifesto for the EU elections. Our focus is very much on maintenance, sustainable investment and decarbonisation, all of which require the expertise of the consulting engineering sector.

Carbon capture, utilisation and storage

The EU’s communication on the Climate Target 2040 stresses the crucial role of carbon capture and utilisation/storage

(CCU/S) technologies in achieving net zero emissions by 2050, and transitioning towards absolute negative emissions thereafter. CCU/S presents a pathway to climate targets within the stipulated timeframe and is set to play an integral role in combating climate change.

However, the focus must squarely rest on prioritising green carbon capture practices. While the primary objective for Europe’s climate journey remains the reduction of emissions, there are sectors where carbon emissions simply cannot be eliminated entirely. That is where CCU/S steps in as a complementary measure.

Yet, despite its promise, CCU/S is still in its infancy, with only a handful of pilot projects dotting the landscape across the EU. Therefore, urgent and increased investment in CCU/S technologies is imperative if we are going to scale up deployment and maximise its effectiveness in mitigating emissions, as highlighted in the EU’s communication on industrial carbon management.

Key considerations

However, the successful execution of a robust EU clean industrial carbon management strategy hinges on several key considerations. Firstly, recognising the identical nature of carbon molecules, whether they originate from fossil or biogenic sources, is paramount. This understanding is crucial for assessing the economic viability of carbon capture, transport, and storage/utilisation, which depend on the unique characteristics of emission sources and the distance to storage/utilisation sites.

Strategic swaps of biogenic carbon with fossil carbon can significantly minimise CO2 transport costs, especially in regions like Northern Europe where cost-effective carbon capture and storage (CCS) for biogenic

CO2 is feasible. On a smilar level, swaps in regions like Southern Europe or Northern Africa, where cost-effective hydrogen production is viable, can support efficient production of renewable fuel-natural based organic (RFNBO), benefiting hard-to-abate sectors.

Robust CO2 pipeline network

Moreover, the timely development of a comprehensive CO2 pipeline backbone is essential. Presently, the economic feasibility of developing CCS, and often CCU as well, heavily relies on proximity to coastal areas. Long-distance transport by truck is only viable for relatively short distances. Without a robust CO2 pipeline network, landlocked CO2 point sources and related industries are at a considerable disadvantage and may encounter obstacles in their development.

Lastly, it is imperative to adopt a comprehensive and integrated approach to the transportation of low-emission products vital for the green transition. Initiatives related to CO2 infrastructure must be synergised with the European hydrogen network, as well as the transport of e-methanol and green ammonia. Moreover, while ports and terminals are not explicitly mentioned in the

communication as part of any CO2 transport infrastructure, they deserve special consideration. The substantial development of – and investment in – port/terminal infrastructure are prerequisites for a well-functioning CO2 transport network and are equally crucial for the transportation of other green fuels. Hence, integrating these elements into the broader framework of the European carbon management strategy is paramount for achieving a sustainable and efficient green transition.

World Engineering Day

How crucial are consulting engineers in this equation? Without their expertise in calculations and guidance on selecting the most suitable materials for location, climate, and building use, the EU’s interim 2040 climate target remains out of reach. These engineers are instrumental in designing and implementing robust and sustainable public infrastructure, including the essential transportation infrastructure for captured carbon. Placed at the core of the construction ecosystem, consulting engineers connect various stakeholders, supporting them through every project phase.

As the European climate agenda approaches a crucial turning point towards achieving net zero emissions, the significance of consulting engineers cannot be overstated. Therefore, it is most fitting that this contribution was marked on World Engineering Day on 4 March, under the theme “Engineering solutions for a sustainable world.”

Key take-aways from recast of EPBD

Recent updates to the European Union Directives covering Energy Performance of Buildings (EPBD) and Energy Efficiency (EED) will lead to significant changes in decarbonising new and existing buildings.

This article – by John Burgess, MEP Engineer, Energy Auditor and Energy Efficient Design

Facilitator working in Arup’s awardwinning Cork Office – aims to raise awareness of these changes for those involved in the design, procurement, construction and operation of buildings. It is expected by the author that the reader has access to the latest EPBD and EED when reading this article.


The Energy Performance of Buildings Directive (EPBD) first came into being on 16 December 2002 when Directive 2002/91/EC was signed off by the then President of the European Parliament, Pat Cox. The EPBD introduced the need for buildings to be given an energy rating similar to what you would see when purchasing white goods for the home. In Ireland, the SEAI introduced the Building Energy Rating (BER) certification scheme under the astute leadership of Kevin O’Rourke to meet this requirement. In 2009, Ireland introduced the need for Display Energy Certificates (DECs) in all public buildings, through

Statutory Instrument SI-591-2008. This led temporarily to the build-up of an informative database of a building’s full energy footprint, contributed to by facilities management teams in local authorities and public service bodies. Around 2015, the DEC process was updated to ensure the assessment is carried out by registered BER Assessors.

The first recast of the EPBD in 2010 (Directive 2010/31/EU) introduced the concept in Article 9 of Nearly Zero Energy Buildings (NZEB). In 2018, Ireland’s Part L Regulations for Buildings Other than Dwellings implemented the requirements of the first recast of the EPBD.

The EPBD was amended twice in 2018 through Directive 2018/844/EU and Regulation 2018/1999/EU.

Directive 2018/844 introduced the need for active Building Automation and Control Systems (BACS), the long-

term renovation strategy, EV charging and the term “Smart Readiness Indicator.”

Now, in 2024, we are about to see the release of the second recast of the EPBD by the EU Industry, Research and Energy Committee, chaired by rapporteur Ciarán Cuffe, MEP, with assistance from shadow rapporteur Sean Kelly, MEP. I would expect the requirements of the second recast of the EPBD to find their way into the building regulations in a shorter time-frame within a year of the Directive coming into force. This article endeavours to update the reader on the changes of consequence to those involved in the design and construction of buildings.

Also worthy of note is the Recast of the Energy Efficiency Directive (EED) 2023/1791/EU, making considerable updates to Directive 2012/27/EU. The EED has considerable implications for buildings, most notably in Chapter II – Exemplary Role of the Public Sector – Articles 5, 6 & 7 and in Chapter III –Efficiency in Energy Use, Articles 8 & 9 Energy Efficiency Obligation Scheme and Article 12 Energy Management Systems and Energy Audits.

Key initiatives of the recast EPBD Article 1 – Subject matter of the EPBD and what it is intended to cover. Article 2 – Definitions (selected for this synopsis).

1. Zero Emissions Building (ZEB) is expected to provide the remaining low amount of energy needed, refer to Annex III, from renewable energy sources generated on-site, from a renewable energy community (RED 2018/2001/EU), or from a district heating and cooling system as per Annex II. Annex III sets the total annual primary energy use of a new zero-emission office building in the oceanic zone to be less than 70kWh/ m2.yr. A ZEB shall not cause any on-site carbon emissions from fossil fuels.

Energy Performance of Buildings Directive

2. Renovation passport is a document that provides a tailored roadmap for the renovation of a specific building in several steps that will significantly improve its energy performance.

3. Deep renovation transforms a building:

a. Before 1 January 2030 into an NZEB.

b. After 1 January 2030 into a ZEB.

4. Life cycle Global Warming Potential (GWP) is an indicator that quantifies the GWP contributions for all stages of a building’s life cycle, from sourcing of raw materials through its operational life, to recovery and disposal of the building at end of life.

5. Digital building logbook is a repository for all building data related to energy performance such as BERs, renovation passports, smart readiness indicators and technical building systems which facilitates informed decision making.

Article 3 – National Building Renovation Plan requiring all member states to establish a plan to renovate all buildings into highly energy efficient and decarbonised building stock by 2050.

Article 4 – Adoption of a methodology for calculating energy performance of buildings in accordance with a common general framework set out

in Annex I. Note that the primary energy factor (PEF) to be used in lieu of a member state’s calculated PEF is 1.9. Ireland has set the PEF at 1.75 from 2023 for use in the DEAP and NEAP energy rating assessment tools.

Article 5 – Setting of minimum energy performance requirements for buildings.

Article 6 – Calculation of cost-optimal levels of minimum energy performance requirements in accordance with Annex VII.

Article 7 – New buildings to be ZEB in accordance with Annex III from 1 January 2027 for buildings occupied or owned by public authorities, and from 1 January 2030 for all new buildings. Also, the GWP for the building is to be calculated in accordance with Annex III and disclosed through the BER (EPC) for the building from 1 January 2027 for new buildings with a usable floor area greater than 2,000m2, and from 1 January 2030 for all new buildings.

Article 8 – Existing Buildings: member states to set out the minimum energy performance requirements of the building or the renovated part thereof.

Note that Article 9 in the previous version of the EPBD regarding NZEB has been deleted.

Article 9 – Minimum Energy Performance standards to be at, or above, Class E for buildings by 1 January 2030 and dwellings by 1 January 2033. Member states to set out a programme for achieving higher performance classifications by 2040 and 2050, in line with the pathway for transforming the national building stock into ZEBs.

Article 10 – Renovation Passport Scheme to be introduced by member states before 31 December 2024. The renovation passport shall be issued by a qualified and certified expert following an on-site visit, and shall set out a sequence of steps with the objective of transforming the building into a ZEB by 2050 at the latest.

Article 11 – Technical Building Systems: member states shall require ZEBs to be fitted with measuring and control devices for the monitoring and regulation of indoor air quality. In existing buildings, the installation of such devices shall be required, where technically and economically feasible, when a building undergoes a major renovation.

Article 12 – Sustainable Mobility EV Charging infrastructure: This sets out cabling infrastructure for EVs and electric bicycle charging with the same number of bicycle parking spaces as there are for cars.

Article 13 – The EU Commission will introduce a common Union scheme for the rating of Smart Readiness of Buildings. The rating shall be based on an assessment of the capabilities of a building, or building unit, to adapt its operation to the needs of the occupant and the electricity grid, and to improve its energy efficiency and overall performance. This will see an increase in the adoption of smart energy metering services with the distribution system operator (DSO), so as to affect loadside and demand side management of electricity use in the building. This

will help with improving grid resilience at times of peak demand and take advantage of low carbon electricity at times of high renewable energy generation on the grid.

Article 14 – Data Exchange: member states shall ensure that the building owners, tenants and managers can have direct access to their building systems’ data. At their request, the access or data shall be made available to a third party. Member states shall facilitate the full interoperability of services and of data exchange within the Union.

Article 15 – Financial Incentives and Market Barriers: member states shall provide appropriate financing, support measures and other instruments able to address market barriers and stimulate the necessary investments in energy renovations in line with their national building renovation plan, and with a view to the transformation of their building stock into ZEBs by 2050. Building services engineers and energy (and materials) decarbonisation specialists will find their skillsets to be in demand to oversee energy efficiency upgrades funded through financial aid programmes promoted by the Government.

Article 16 – Energy Performance

Certificates: the BER scales will need to align “A” rated buildings with ZEBs. Validity of the BER will reduce from 10 years to five years for buildings with a rating of “D” or lower.

Article 17 – Issuing of EPCs /BERs: the

threshold on floor area of 250m2 has been removed. EPCs/BERs are required for buildings which are constructed, have undergone a major renovation, been sold or rented out to a new tenant, or when a rental contract is renewed.

Article 18 – Display of Energy

Performance Certificates: for public buildings, the EPC/BER, if issued, shall be displayed in a prominent place to the public. Note that this does not circumvent Irish Statute SI-591-2008 which also sets out requirements for the display energy certificates in public buildings.

Article 19 – Databases for energy ` for energy performance of buildings which allows data to be gathered on the energy performance of buildings, and on the overall energy performance of the national building stock. The database shall allow data relating to energy performance certificates, inspections, the building renovation passport, the smart readiness indicator and the calculated or metered energy consumption of the buildings covered, to be gathered.

For the purpose of this Directive, building systems data shall include at least all data related to the energy performance of building elements, the energy performance of building services, building automation and control systems, meters and charging points for e-mobility.

Article 20 – Inspections: This sets out requirements for inspections of

HVAC systems with a rated capacity of more than 70kW, although there is an alternative route to provide advice to users regarding the replacement of heat generators and other modifications to the technical buildings systems. Article 20 sets out the minimum requirements for building automation and control systems. These requirements have already been implemented in Part L 2018 of the Building Regulations (Conservation of Fuel and Energy) for Buildings other than Dwellings through the Technical Guidance Document (TGD) clause noting:

For buildings with an effective rated output for air-conditioning systems of over 70kW, a building automation and control system should be installed for the building with the following functions:

(a) continuously monitoring, analysing and allowing for adjusting energy usage;

(b) benchmarking the building’s energy efficiency, detecting losses in efficiency of technical building systems, and informing the person responsible for the facilities or technical building management about opportunities for energy efficiency improvement;

(c) allowing communication with connected technical building systems and other appliances inside the building, and being interoperable with technical building systems across different types of proprietary technologies,

devices and manufacturers, and (d) monitoring the energy provided by renewable energy technologies. A point to be considered here by those who manage and operate buildings, including those in the public sector, will be the need to engage with cloud-based data analytics providers. There is a new stream of service offerings becoming available through cloud-based data analytics. Companies operating in this domain can harvest instantaneous BMS data on a continuous basis and provide support in monitoring, analysing, benchmarking and detecting deviations in efficiency of technical building systems. The benefits of such services can also prove substantial during the commissioning process and ‘Soft Landings’ (BSRIA) handover phase of the building.

Article 21 – Reports on the inspections of HVAC systems shall be issued after each inspection to the owner or tenant of the building, and also uploaded to the national database referred to in Article 19.

Articles 22 to 34 – The remaining articles 22 to 34 refer to other elements that would be managed by the member state, noting that the second recast of the EPBD would come into force 20 days after its publication in the Official Journal of the European Union. The final text was agreed by the Parliament and the Council on 7 December 2023 and is now awaiting endorsement. Final votes are expected in Q1 of 2024 and implementation to be in place shortly thereafter.

Overlap with the EED

With reference to the Recast of the Energy Efficiency Directive (EED) 2023/1791/EU mentioned in the introduction:

Article 6 – Exemplary role of public bodies’ buildings: each member state shall ensure that at least 3% of the total floor area of heated and/or cooled buildings that are owned by public bodies is renovated each year to be transformed into at least NZEBs or ZEBs in accordance with Article 8 of the second recast of the EPBD.

Article 7 – Public procurement shall purchase only products, services, buildings and works with high energyefficiency performance.

Articles 12 to 17 – These set out the minimum requirements for energy metering, sub-metering and billing.

Impact on the building industry

The second recast of the EPBD will lead to several significant changes to the design and procurement of high-performing, energy efficient buildings, not least of which will see the phase-out of oil and gas fired boilers. This is already the case for public sector buildings which need to install heating systems powered from the electricity grid as mandated by the Minister for the Environment, Climate and Communications on 14 July 2022.

The use of heat-pumps to heat buildings should see an increased focus on the recuperation of waste heat. The same focus that is applied

rigorously to the safe and efficient operation of MEP systems will need to be applied to the building envelope. Buildings maintenance teams will need to be trained and empowered to eliminate energy waste, and to operate buildings effectively in order to deliver high standards of indoor air quality (IAQ).

Ireland’s building regulations will continue to see more updates in response to the second recast of the EPBD. The subject of IAQ will need to be addressed in the building regulations. Perhaps the recentlypublished Code of Practice for Indoor Air Quality by the Health and Safety Authority will help to set the minimum standards which could be referred to in Building Regulations Part F and/or Part L. Also, Building Regulation Part J for Heat Producing Appliances will require an update to address the need for high efficiency heat-pumps that meet the requirements of the F-Gas regulations.

Opportunities for building services engineers

Building services engineers have an important role to play in driving improved energy efficiency and indoor air quality in our buildings. Specialist service offerings will grow in the areas of energy data analytics, energy modelling, energy auditing and whole-life carbon GWP assessment of the building’s life cycle. Building services engineers can take the lead in developing and fulfilling these roles.

Gary O’Sullivan reports from Chicago ASHRAE Winter Conference 2024

In this report from the 2024 ASHRAE Conference in Chicago, Gary O’ Sullivan, Managing Director, OSENG and President, ASHRAE Ireland Chapter (right), provides a personal account of his experience of the combined conference and related AHR Expo in the Windy City.

It was my privilege as President of the ASHRAE Ireland Chapter to attend the annual ASHRAE Winter Conference 2024 in Chicago. I travelled with several delegates from our long-term chapter supporters which included Ardmac, Kirby Group, PM Group, Entropic, Sygma Automation and OSENG.

The ASHRAE Conference – a mecca for those passionate about heating, ventilation, air conditioning and refrigeration – was a vibrant tapestry of technical workshops, committee meetings, student discussions, and young and old engineers united by the thirst for professional growth.

The conference officially opened for registration on Friday, 19 January and ran until Wednesday, 24 January. Unfortunately, several of us who had travelled had to return to Ireland on Monday night and were unable to attend all the seminars planned over the week. Thankfully though,

the speakers’ papers were made available to all who had registered to attend. There is still some light reading ahead of us all.

Saturday was left for registration and some sight-seeing. This included the Willis Tower Sky Deck, United Center for the Bulls match, and the ASHRAE welcome party in The Old Post Office in Chicago, built in 1921. This was attended by ASHRAE members from across the USA, Europe, Middle East and Asia. It included everyone from students to retired engineers.

It was a delight to see the integration of those starting their careers and those at the end, all with the one clear vision for a healthy and sustainable built environment for everyone. As one delegate described it to me – “ASHRAE is a family for life whose purpose is to ensure a future for our children and their families.”

At the ASHRAE Winter Conference in Chicago were (l-r) Cailin MacPherson, MacPherson Engineering with Gary O’Sullivan, OSENG; Conor Murray, 3Dimension; Tunji Faturoti, Ethos Engineering; Howard Neville, PM Group; and Elizabeth Jedrlinic, Trane.

The conference was a place for members across the world to meet and discuss challenges, opportunities and solutions for issues across the built environment. These sessions were led by the many technical committees with TC9.11 Clean Spaces, TC9.9 Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment, TC9.10 Laboratory Systems among those of particular interest to myself and also my travelling partners from Ireland.

For example, TC9.11 is concerned with air conditioning systems for cleanrooms and spaces. This covers process, product and facility air conditioning, and related process ventilation for research and development, manufacturing, assembly, test and clean medical areas. It also includes electronic, microelectronic, pharmaceutical, and aerospace facilities and operating rooms.

We were delighted to support our 2022-2023 Past-President, Conor Murray, at the conference where he presented multiple papers to delegates over the week on the following topics:

• Design of HVAC Systems for Aseptic Manufacturing Facilities;

• The Opportunity and Energy Density Challenge of Lithium-Ion Battery Dry Cleanrooms in Climate Rebalancing and Carbon Reduction from Fossil Fuels.

There are plans for further papers to be authored and presented by Irish members at the next ASHRAE global conference.

As part of the weekend, the Ireland Chapter, along with other regions, arranged an Irish-themed networking event at the Emerald Loop Irish Bar in downtown Chicago. This was attended by ASHRAE members from multiple regions including Chicago, Boston, New York, Spain, Portugal, Serbia, Romania, the UK and Israel, to name but a few.

The event was also attended by Ginger Scoggins, ASHRAE Leaders’ President, Dennis Knight, Incoming President and other Executive Council members. Those from the CIBSE delegation present included Adrian Catchpole, President, and Anastasia Mylona, Technical Director, while some representatives from the IDA also joined in.

Pipes & Drums band bringing the evening to a close with a march through the inside of the bar. It was a most enjoyable night with many memories created and new friendships forged.

On the Monday I had the pleasure of speaking to over 70 members on the subject of “Best Practices of a MentorMentee Relationship” where I presented, along with my colleagues Conor Murray (3Dimension) and Tunji Faturoti (Ethos Engineering), about the Ireland Chapters Mentor-Mentee Programme that was initiated in 2022. We discussed how we have implemented our programme, the lessons we learned along the way, and the obstacles we had to overcome.

The key focus on the programme is to pass on the experience from the senior engineers within our industry to the next generation. There is a vast amount of knowledge and leadership that is currently being lost from the industry because of the retiring engineers exiting the sector. However, if we can pass on some of that knowledge base to the next generation, then maybe we can help them progress their career paths, while also helping to

achieve our decarbonisation targets by 2030 and 2050.

The ASHRAE Ireland Chapter is about to commence the programme for the coming year where we will be pairing ten mentors and mentees together. I’m also delighted to announce that our annual student scholarship fund is now open to all ASHRAE student members.

AHR Expo

To finish off our visit we attended the AHR Expo. The atmosphere was electric, charged with the collective ambition of 50,000 individuals who converged on the exhibition hall over the three days.

This event was less an expo and more a gateway to the future, showcasing the latest and greatest from over 1600 HVACR manufacturers. As an engineer, I found it extremely interesting, but did note that some of systems being prestented were solutions we have been using in Europe for years. In some cases we could see that the US is ahead but in other ways I think they could learn from what we are doing in Europe by way of sustainable design.

The same applied to controls, automation and the use of renewable technology. As I understand it, this is because in Europe we issue Directives that all member states agree on and implement, whereas in the US, regularity control comes under the jurisdiction of each individual state.

Looking ahead, ASHRAE has been working hard to assist with the creation of a roadmap for building decarbonisation and is actively involved in developing contents for Standard 62.1 Indoor Air Quality, Standard 241 Control of Infectious Aerosols and energy standards such as 90.1.

Next stop: Orlando, 10 to 12, February, 2025, when the Ireland Chapter and friends will once again head off to the ASHRAE Conference in the US.

Losing the plot on skills?

Desperate times call for desperate measures but really, have we totally lost the plot when it comes to skills shortages? Soon to be Taoiseach and current Minister for Further and Higher Education, Simon Harris, TD, recently announced details of a pilot programme to train prisoners to retrofit homes. He believes the scheme will help reduce the risk of re-offending as many former prisoners do not have specific skills to help them adapt to a new life.

Meanwhile, the new Warm Home Hub in Galway will provide training courses in retrofitting for students, unemployed citizens, women and people with special needs with the aim of helping them to upskill and secure “green jobs”.

These are very laudable objectives from a social inclusion point of view, but is it the right solution for a skills shortage in what is – or should be – a highlyskilled sector?

Gerry McDonagh retires

CIBSE Committee beware!

Congratulations to CIBSE Ireland Committee members, Mona Duff and Ryan Loney, on the birth of their respective daughters, Nina (left) and Emily right). Both are obviously determined to swell the ranks of the WiBSE network.

The news did prompt Michael Curran to question what was in the air at the CIBSE AGM nine months previously, and indeed to caution all that the 2024 AGM is but weeks away!

Congratulations to Gerry McDonagh on his recent retirement from RSL Group. Gerry has been synonymous with the evolution of the refrigeration sector in Ireland for decades, not just reflecting industry changes, but helping shape and develop them. His vast experience, knowledge and enthusiasm will be missed by all.

His long-time colleague, Seamus Kerr, has taken on the role of MD, and he will now guide the RSL Group as it moves forward under the direction of new owners IPCOM.

Gerry, I hope you enjoy every moment of the next phase of what hasobviously been a fulfilled life to date.

Fabric first forever

With an abundance of cutting-edge products and innovative technology on display at the SEAI Energy Show, the Best Practice Arena nonetheless reinforced the key message when it comes to retrofit … fabric first has got to be the priority.

The need for a holistic approach to all solutions was illustrated by the clever sequence of demonstrations which emphasised the fabric-first principle with insulation, and then explained how everything from air tightness tests through to ventilation, solar panels and heat pumps fit in to the overall picture.

Our photograph shows Chris Halligan delivering the ventilation module at the Best Practice Arena.

Heat pumps are now mainstream

Heat pumps are now most definitely mainstream if the recent SEAI Energy Show is to be an indicator. They dominated the product displays and featured on just over half of the Energy Show Product of the Show Awards, across the four primary awards’ categories. Now all that remains is to ensure that they are appropriately, and correctly, installed.

Hirsute Martin

I see that Paul Martin has joined the ranks of us whiskered males. Looks very impressive Paul, and especially so the strong colour match with the hair. At your age I’d have expected to see at least a tiny amount of the “salt and pepper” effect!

All connected.
