Message from Er. Chan Ewe Jin, President, The Institution of Engineers, Singapore (IES)

The Institution of Engineers, Singapore (IES) is proud to be a key partner of the World Engineering Day for Sustainable Development (WED). Our continued involvement in this global initiative is a testament to our unwavering commitment to advancing the engineering profession and championing sustainability.

Engineering is more than just a technical discipline – it is a powerful force for progress, bridging the gap between ambition and action to make the United Nations Sustainable Development Goals (SDGs) a reality. By harnessing engineering ingenuity, we can create innovative solutions that address critical global challenges, from climate change and resource scarcity to urbanisation and poverty.

At the heart of our WED activities is the annual Charles Rudd Distinguished Global Lectures (CRDGL). Held on 11 February in a hybrid format, this year’s CRDGL united leading experts, innovators and thought leaders from the global engineering community.

The theme ‘Towards a Sustainable World: Engineering the Way Forward’ fostered dynamic exchanges of insights, exploration of emerging technologies and collaborative solutions to tackle

complex global issues. Sustainability should not be a mere industry trend – it must be deeply embedded in the way engineers think, design and implement solutions. Recognising this imperative, IES launched the Chartered Engineer Sustainability Programme last year to empower engineers with the skills and expertise to lead sustainability efforts within their industries. By fostering a growing network of sustainability-focused professionals, IES envisions a future where engineering solutions are not only innovative but also environmentally and socially responsible.

Inspiring the next generation is equally critical on the sustainable development journey. IES continues to organise the National Engineers Day (NED) annually, a flagship event designed to inspire and encourage young minds to adopt sustainable approaches in their projects and future careers.

To be held in July 2025 featuring hands-on challenges, competitions and project showcases, NED 2025 will once again instill the values of sustainability among students, preparing them to be conscientious engineers of tomorrow.

Looking ahead, I encourage all engineers to join us at this year’s World Engineers Summit (WES), themed ‘Shaping Tomorrow: Engineering Smart Sustainable Cities’. This global gathering will offer invaluable opportunities for collaboration, learning and the exchange of best practices in sustainable urban development.

Let us continue to challenge the status quo, rethink what is possible and ensure that engineering is not just a tool for development, but a driving force for a resilient, sustainable future.

Message from Engr. Mustafa B. Shehu, President, World Federation of Engineering Organizations (WFEO)

Dear Distinguished Colleagues,

Let me begin by thanking the President, Executive Council and entire membership of the Institution of Engineers, Singapore, for inviting me again this year to give a Message at the 6th World Engineering Day celebrations which is taking place globally, while the main event is taking place at the UNESCO Headquarters in Paris.

I also want to thank you for the unflinching support you are giving me as President of WFEO, since my assumption of office in October 2023.

You are all aware of the fact that my term as President of this prestigious organisation is terminating in October this year during the 2025 General Assembly (GA) that will be taking place in Shanghai, the Peoples Republic of China. As continuation of your support for me, I expect huge attendance and effective participation from the engineering community in Singapore.

The most interesting aspect of the 2025 GA is the fact that I am handing over to ‘your own man’ and my good friend, Er. Tan Seng Chuan. It is therefore an occasion we should all look forward to, with excitement and jubilation. I also expect you to give him the

maximum support he needs to meet the expectations of the global engineering community that has confidence in him by voting for him to lead this global organisation.

Distinguished engineers, ladies and gentlemen, the theme of this year’s WED, ‘Shaping a Sustainable Future Through Engineering’, could not have come at a better time than this period when the United Nations declared the International Decade of Science for Sustainable Development (IDSSD) and instructed UNESCO to drive its implementation through an Executive Committee in which WFEO is an important member. The rationale behind the declaration of the Decade is that the world is not on track to reach

the Sustainable Development Goals (SDGs) by 2030. For example, to reach universal coverage for safe drinking water, sanitation and hygiene by 2030, current rates of progress will need to increase fourfold, according to the United Nations’ Sustainable Development Report (2022). For at least 3 billion people, the quality of the water they rely upon is unknown, for lack of monitoring.

This, among other needs, are the challenges we must address as engineers, to achieve the aims and objectives of the Decade.

I therefore call on all of you to contribute your expertise and knowledge towards the success of this global objective.

As I conclude, I want to urge IES and all of you as corporate entities and individuals, to make sure that your contributions are felt by the society we live in and that we ensure training and supporting our youth in all aspects of engineering to equip them adequately to face the daunting challenges of the future.

While looking forward to seeing you in any of the WFEO functions or in Singapore, I once again wish all of you a Happy World Engineering Day!

Mustafa B. Shehu President, WFEO

Advancing Singapore’s low-carbon built environment

The Building and Construction Authority (BCA) highlights two case studies that demonstrate green engineering.

Singapore’s urban landscape is undergoing a quiet yet transformative revolution, where engineers are at the forefront of sustainable development. As global concerns over climate change intensify, Singapore has taken decisive steps towards reducing its carbon footprint, with a bold target to achieve net zero emissions by 2050. Given that buildings contribute approximately 20% of the nation’s carbon emissions, the built environment plays a pivotal role in this transition to a lowcarbon, climate-resilient future.

ENGINEERING THE GREEN TRANSFORMATION

To support this transition, the Building and Construction Authority (BCA) launched the Singapore Green Building Masterplan in 2021, as part of the broader Singapore Green Plan 2030. The masterplan, developed in collaboration with the Singapore Green Building Council (SGBC), sets ambitious sustainability standards in the built environment, encapsulated in its ‘80-80-80 in 2030’ targets:

• 80% of buildings (by Gross Floor Area or GFA) to be green by 2030

• 80% of new developments (by GFA) to be Super Low Energy buildings from 2030

• 80% improvement in energy efficiency for best-in-class green buildings (compared to 2005 levels) by 2030

These targets set out the direction for the built environment sector to work towards achieving the country’s ambitions of achieving net zero emissions by 2050.

Significant strides have been made towards reaching these 80-80-80 goals. As of December

2024, about 61% of the building stock (by GFA) has been greened. Achieving the second 80% target requires the mainstream adoption of Super Low Energy, Zero Energy and Positive Energy buildings. Research and innovation remain critical drivers under the masterplan, to push the boundaries of energy efficiency to achieve the third 80% target.

TECHNOLOGICAL ENABLERS IN GREEN ENGINEERING

Technology development is key to realising these sustainability goals. This includes driving more passive design strategies, through naturally ventilated design and alternative cooling strategies, such as hybrid cooling. Such initiatives not only foster innovation in sustainable design and construction but also challenge engineers to develop and implement creative, cutting-edge, energy-efficient solutions, as well as adopt green building products and materials, and low-carbon building practices.

However, achieving deep decarbonisation requires a collaborative approach, by breaking down silos across the built environment value chain and fostering multidisciplinary cooperation.

THE VALUE OF GREEN BUILDINGS

A 2024 report by Cushman & Wakefield, ‘Banking on Green Office Buildings in Singapore’ underscores the tangible benefits of green buildings. The study reveals that Green Mark-certified buildings command higher rental yields and occupancy rates compared to buildings that are not Green Mark-certified. This reflects an increasing demand for sustainable, energy-efficient and

wellness-centric workplaces. There are also long-term cost savings through improved energy efficiency and reduced operational expenses, for the building owner.

Beyond financial benefits, green buildings enhance occupant well-being and productivity. Employees in these working environments report higher satisfaction levels, leading to improved productivity and reduced absenteeism. As sustainability and employee wellness become key considerations, green buildings are emerging as strategic assets in the commercial real estate market.

CHAMPIONING SUSTAINABLE PROJECTS IN SINGAPORE

Case Study 1

The Singapore Land Tower, a 44-year-old commercial building, exemplifies the potential of sustainable retrofitting. This project, recognised as one of the winners of the SGBC-BCA Leadership in Sustainability Awards in the Building Project Leadership in Sustainability (Carbon Performance) category, showcases the potential for older buildings to embrace sustainability and remain relevant in today’s market.

Rather than demolishing and rebuilding, Singapore Land Group (SingLand) undertook an extensive asset enhancement initiative (AEI) that earned a Green Mark Platinum certification. By prioritising retrofit, more than 50% of embodied carbon emissions were avoided. Key enhancements included a double-glazed curtain wall, energyefficient lighting, and enhancing the air conditioning and mechanical ventilation systems.

The project team, comprising Arup Singapore Pte Ltd as the ESD

Consultant and G-Energy Global Pte Ltd as the Green Mark Consultant, demonstrated how existing buildings can be revitalised to meet contemporary sustainability standards.

Case Study 2

CapitaSpring, a 51-storey, 280 m tall, biophilic skyscraper, showcases the seamless integration of nature into urban spaces. This Green Mark Platinum certified development, owned by CapitaLand Development, was engineered by Arup Singapore Pte Ltd as the ESD Consultant, C&S Consultant and Facade specialist, alongside Beca Carter Hollings & Ferner and Squire Mech as the M&E Consultant.

The project features the iconic Green Oasis, a 35 m high and 42,900 ft2 open-air garden that mimics a tropical rainforest, suspended 100 m above ground. This naturally-ventilated semioutdoor space exemplifies the building’s biophilic design principles. The Sky Garden on level 51 hosts Singapore’s highest urban farm, supplying fresh and sustainable ingredients for the building’s F&B tenants.

CapitaSpring prioritises occupant health and well-being, through green mobility, active lifestyles, mental wellness and healthy diets. State-of-the-art research, design and technology have been employed to ensure optimal occupant health, comfort and energy efficiency. Its holistic approach earned CapitaSpring recognition in the SGBC-BCA Leadership in Sustainability Awards, under the Building Project Leadership in Sustainability (Health & Wellbeing) category.

THE ROAD AHEAD

As Singapore advances towards a low-carbon built environment, engineers remain instrumental in driving sustainability innovations. The Singapore Building Carbon Calculator, which won the IES Sustainability Award and the ASEAN Outstanding Engineering Achievement Award in 2024, exemplifies this spirit of progress.

The Singapore Building Carbon Calculator was developed through collaborative efforts by JTC Corporation, BCA, SGBC and the NUS Energy Studies Institute, to help the built environment sector make more informed decisions

about sustainable materials and construction methods.

Through engineering innovation, Singapore is not only constructing greener buildings but also shaping a sustainable future for generations to come.

Setting sail towards net-zero

The Maritime and Port Authority of Singapore (MPA) is raising ambition to accelerate decarbonisation on all fronts.

Climate change has significant implications for the shipping industry. As a low-lying island nation, Singapore is particularly susceptible to rising sea levels which pose a threat to coastal areas and infrastructure. Urgent action is crucial to safeguard the environment as well as protect the well-being and livelihoods of current and future generations.

As the steward of Singapore’s global hub port and international maritime centre, the Maritime and Port Authority of Singapore (MPA) plays a pivotal role in maritime decarbonisation, at three levels.

International collaborations Internationally, MPA collaborates with Member States of the International Maritime Organization (IMO) and other multilateral fora, to shape global measures to achieve net-zero emissions by or around 2050.

MPA is also working with governments and port authorities to align efforts across stakeholders in the value chain, such as establishing Green and Digital Shipping Corridors with international partners, to facilitate the transition to low- and zero-emission fuels.

Maritime Singapore

To support the decarbonisation of Maritime Singapore, MPA is accelerating efforts with industry and research partners to trial and pilot low- and zero-emission fuels. This includes developing fuel and bunkering standards as well as building the supply chain and infrastructure for bunkering such fuels.

MPA is also leading the electrification of the domestic harbour craft sector which includes coalescing research and technical know-how for a new,

greener generation of harbour craft, and establishing the charging infrastructure masterplan for electric harbour craft. Moreover, MPA is spearheading initiatives with industry and unions to equip the Maritime Singapore workforce with the necessary skills for the green transition.

Embracing

sustainability

As an organisation, MPA is committed to achieving the public sector’s target to peak emissions around 2025 and achieve netzero emissions by 2045, under the GreenGov.SG initiative. MPA is optimising the deployment of operational assets and exploring the use of biofuel and renewables to reduce emissions.

Smart Facilities Management (FM) is being implemented across MPA facilities to optimise and reduce usage of brown electricity, and an integrated smart FM platform is planned to be operational by 2027 to monitor smart FM dashboards.

MPA is intensifying solarisation efforts at offshore sites and waterfront facilities. Plans are underway to explore the installation of a solar photovoltaic and energy storage system for decarbonisation

of Pulau Satumu’s Raffles Lighthouse.

MPA is also planning to progressively expand the solar panel coverage at Marina South Pier, which will transform it into the first public maritime terminal to achieve net-zero emissions. Upon implementation, this will support the charging of electric harbour craft (eHC), as part of the national eHC charging infrastructure.

Additionally, MPA is developing three net-zero energy buildings to strengthen Singapore’s position as a premier global hub port and leading international maritime centre.

MPA is also actively fostering a sustainability culture within the organisation, through various forms of communication, events and training, to instill eco mindsets and habits in its staff.

Addressing the impact of climate change on the maritime sector requires collective commitment and innovation. It is imperative for all stakeholders to collaborate and take decisive steps towards a greener, more resilient future.

Together, a meaningful difference can be made in safeguarding Singapore’s environment, for generations to come.

This intensification of efforts includes the expansion of the cool coatings initiative to all existing HDB estates islandwide, as well as the inclusion of new initiatives, such as the installation of smart electric submeters, under the GTP.

The GTP is a plan to bring sustainable living to all existing HDB towns, with large-scale implementation of green features to improve the residents’ quality of life. It is a key initiative under the Singapore Green Plan which aims to build a more sustainable future for Singapore, in the face of climate change.

EXPANSION OF THE COOL COATINGS INITIATIVE

In 2021, HDB and Tampines Town Council launched a joint pilot project to apply cool coatings – a type of specialised paint, containing additives that reflect the sun’s heat, reducing surface heat absorption and emission – to approximately 130 HDB blocks in Tampines. With the use of such paint, HDB aims to reduce the ambient temperature of the site, enhancing comfort for residents and reducing energy consumption.

To monitor the ambient temperature and collect data for analysis, sensors were installed on the blocks’ external facades and at the ground level. Findings from the two-year pilot showed that the cool coatings reduced ambient temperatures by up to 2 °C, thereby meeting HDB’s target. Besides enjoying a cooler

environment, residents living in blocks painted with cool coatings also benefitted from a reduction in electricity consumption, as less energy is needed for air conditioning systems to cool their flats.

Following the successful pilot, HDB will work closely with the Town Councils to extend the cool coatings initiative to all existing HDB estates, by 2030. The paints used will be water-based paints containing low volatile organic compounds, similar to conventional paints, and comply with Singapore’s safety and environmental standards.

NEW INITIATIVES TO BE ADDED TO THE GREEN TOWNS PROGRAMME

As the largest housing developer in Singapore, HDB plays a pivotal role in supporting the nation’s commitment to sustainable development. Besides cool coatings, other initiatives under the GTP have seen considerable progress. Building on these successes and to further advance its sustainability targets, HDB, in collaboration with relevant agencies, will introduce additional initiatives in the GTP, including the following:

Installation of smart electric sub-meters

From 2Q2025, smart electrical sub-meters will be installed in the consumer switch rooms of HDB blocks. These sub-meters will enable HDB and Town Councils to monitor and analyse energy consumption patterns and the performance of common services i.e. lighting, water pumps and lifts, at each block.

With this data, Town Councils can compare energy usage across HDB blocks and track the demand and supply of energy usage for individual blocks in the estate. The data collected will also help the Town Councils to optimise their maintenance cycles for common services, as well as detect anomalies such as equipment faults, to minimise downtime.

Green complexes

To reduce the carbon footprint of buildings, HDB will be upgrading and designing 38 HDB-managed complexes, by 2030. The complexes will have the following:

• Solar panels installed on the rooftop and more energy-efficient

Following a successful pilot, the cool coatings initiative will be extended to all existing HDB estates by 2030. Image: HDB.

equipment/fittings to reduce energy usage by 10%.

• Water-efficient fittings to reduce water usage by 10%.

• Machines to turn food waste into compost, reducing waste by 30%.

With these efforts, HDB aims to obtain the BCA Green Mark Super Low Energy (SLE) Certification for four HDB complexes in 2025. Thereafter, it has a target to progressively roll out green initiatives at an average of eight complexes a year.

Beverage container return points In support of the National Environment Agency’s (NEA) Beverage Container Return Scheme, a network of more than 1,000 return points (such as Reverse Vending Machines) will be deployed islandwide, including at HDB-owned and Town Council spaces.

The scheme, which aims to manage packaging waste and increase the recycling rate of beverage containers, will commence on 1 April 2026.

With these inclusions, the original focus areas of recycling rainwater and reducing waste will be subsumed under a broader category on optimising resources.

DRIVING SUSTAINABILITY IN HDB ESTATES

HDB remains committed to driving sustainability and green initiatives across Singapore’s public housing landscape. Moving forward, it will continue to review the progress and explore innovative solutions to enhance the performance of the initiatives, so as to build a sustainable and liveable environment for current and future generations.

STATUS OF INITIATIVES BEING IMPLEMENTED UNDER THE HDB GREEN TOWNS PROGRAMME

Cooling HDB towns

Greenery intensification: HDB has been introducing more greenery in the form of urban farms, extensive greenery or community / allotment gardens to the top decks of selected Multi-Storey Car Parks

(MSCPs) in HDB estates.

This is done through the implementation of the Prefabricated Extensive Green (PEG) Roof Tray System – a lightweight and modular system developed by HDB.

As at end-January 2025, the top decks of 24 MSCPs have been installed with PEG trays and converted for greenery. Of these, five have been planted with extensive greenery, while 19 have been transformed into community / allotment gardens, where residents can plant herbs, vegetables or ornamental plants.

Reducing conventional energy consumption

Solar panels: Under the SolarNova programme, HDB has been installing solar panels on HDB blocks to power common services, such as lifts, lights and water pumps, with green energy.

As at end-January 2025, more than 4,300 blocks have been installed with solar panels. Solar panels for the remaining committed HDB blocks will progressively be installed in batches, over the next two years, where feasible.

Elevator energy regeneration: With the Elevator Energy Regeneration System (EERS), energy generated during lift motions and braking operations, is recovered to power other services within the lift, such as lighting, ventilation and the lift display panel. With the EERS, lift energy consumption can be reduced by an average of 20%.

As at end-January 2025, more than 500 lifts have been retrofitted with the EERS. HDB is in the process of awarding two more tenders which will bring the total number of lifts retroffited with the EERS to 7,400.

Smart LED lighting: To reduce energy consumption in the common areas of HDB estates, HDB is working with Town Councils to implement smart LED lighting.

The smart lighting is equipped with analytics capabilities, as well as smart sensors that can automatically adjust the luminosity of LED lights when

motion is detected. Compared to conventional LED lighting, smart LED lighting can further reduce energy used for lighting, by up to 60%.

Since late 2024, Town Councils have begun replacing approximately 300,000 existing LED lights, that have reached the end of their lifespan, with smart LED lighting.

Promoting green commute

Dual bicycle racks: As at endJanuary 2025, more than 26,500 dual bicycle racks have been installed across 23 HDB towns. By the end of 2025, about 30,000 such racks will be installed islandwide.

Electrical vehicle (EV) chargers: As at end-January 2025, more than 3,600 electric vehicle (EV) chargers have been installed at 850 HDB carparks. HDB is on track to bring the number of carparks with EV chargers to approximately 2,000, by end 2025.

Optimising resources

UrbanWater harvesting system:

The UrbanWater Harvesting System (UWHS) is designed to maximise the volume of rainwater collected, by harvesting stormwater surface runoff from the ground into an underground detention tank.

In 2024, HDB commenced installation of the UrbanWater Harvesting System in Jurong and Yishun, as part of a pilot announced in 2022. Approximately 12 UWHS will be installed in those two towns. As at end-January 2025, in Jurong, one system has been installed, while the remaining three systems will be installed by 4Q2025. In Yishun, works to install the first system will commence in 3Q2025.

E-waste recycling bins: In 2023, HDB worked with the National Environment Agency (NEA) to deploy e-waste recycling bins at Hong Kah North, Punggol Clover and Fengshan Mulberry. Proper disposal of e-waste helps to prevent toxic hazards from polluting the environment and protect human health.

Rejuvenating Singapore’s industrial landscape

JTC’s lifecycle approach to sustainability.

JTC, the master planner and developer of Singapore’s industrial infrastructure, has positioned itself at the forefront of sustainable development in the nation’s industrial sector. As a statutory board under the Ministry of Trade and Industry, JTC plays a pivotal role in shaping Singapore's industrial landscape whilst addressing environmental concerns.

The organisation has aligned its strategies with Singapore’s sustainability targets, including achieving net-zero emissions around 2045, reducing energy and water consumption by 10%, by 2030, and slashing waste disposal by 30% within the same timeframe.

A holistic approach from planning to rejuvenation

To guide its sustainability journey, JTC has established a comprehensive sustainability framework that spans the entire business value chain. The framework covers five key areas –planning and design, construction, lessee/tenant management, operations and maintenance, and rejuvenation.

For starters, JTC integrates sustainability principles from the earliest stage of development. The Punggol Digital District (PDD) exemplifies this approach. As Singapore’s first smart business district and largest Green Mark Platinum mixed-use development, PDD seamlessly incorporates smart technologies, green buildings and community spaces, demonstrating JTC’s approach to sustainable urban planning.

To minimise environmental impact during the construction phase, JTC has implemented guidelines for sustainable material usage. These include requirements for recycled concrete aggregates and materials certified by the Singapore

Green Building Council (SGBC). In collaboration with the Building and Construction Authority (BCA) and SGBC, JTC developed the Singapore Building Carbon Calculator to quantify and manage embodied carbon in construction projects.

JTC also actively engages its lessees and tenants to promote green practices within its industrial spaces. It has introduced green lease policies that set out sustainability requirements for energy and water efficiency. Through initiatives like the Aerospace Open Innovation Challenge, JTC fosters collaboration between industry players and other stakeholders to address sectorspecific sustainability challenges.

In its operations and maintenance, JTC employs a mix of active and passive strategies to reduce energy and water consumption. This includes smart building management systems and innovative solutions, such as web-based design tools for chilled water plant selection, to optimise energy efficiency.

As part of its rejuvenation strategy, JTC has developed a framework for repurposing industrial buildings. At Kolam Ayer Industrial Estate, an existing terrace factory is adapted for continued industrial use. This approach

not only preserves Singapore’s industrial architectural legacy but also significantly reduces carbon emissions associated with demolition and new construction.

Navigating the sustainability journey

Sustainability has become an imperative in the global agenda. Beyond its role as an industrial developer, JTC supports various industry clusters in their economic transformation efforts. With the emerging green economy, the support includes helping companies to decarbonise and leverage sustainability as a competitive advantage. This requires a delicate balance between technological developments, business readiness and the careful pacing of new initiatives to achieve national sustainability targets.

This challenging yet exciting journey requires strong collaboration among industries, government bodies and solution providers, collectively exploring innovative ideas and forging new frontiers in sustainability. Starting small, demonstrating solutions in real-world applications, and building credibility are important steps in navigating this path.

Building a greener future

CPG Corporation’s commitment to decarbonisation.

CPG’s projects, such as

Climate change is one of the greatest challenges of our time, threatening lives, livelihoods, and global weather systems. Since Singapore joined 195 other nations in signing the Paris Agreement in 2015, there has been intensification of decarbonisation efforts by the nation. In November 2024, the Republic submitted a report to the United Nations outlining mitigation measures such as electrifying vehicle fleets and greening buildings to help Singapore cut emissions by nearly 12 megatonnes by 2030. With buildings responsible for an estimated 20% of Singapore’s total emissions, the built environment industry is in a pivotal position to contribute more to decarbonisation efforts.

CPG Corporation (CPG), a built environment firm with multidisciplinary expertise spanning architecture, engineering consultancy, and project, construction and facilities management, has long championed sustainable green design.

Since 2003, CPG has explored innovative ways to integrate nature

into its developments. Many of its iconic projects such as Khoo Teck Puat Hospital, State Courts, Eunoia Junior College, Gardens by the Bay and Jurong Lake Gardens, demonstrate how biophilic design enhances greenery in the built environment or seamlessly integrates buildings with natural surroundings.

nature-based solutions with grey infrastructure to

Complementing this, CPG’s expertise in engineering solutions that enhance energy efficiency has enabled it to deliver 95 Green Mark-certified projects to date, including 44 Green Mark Platinum projects, three Zero Energy Building (ZEB) Green Mark Platinum projects, and two Super Low Energy (SLE) buildings.

As CPG continues leading the green built environment sector, it also aims to accelerate the sector’s transition to a greener future through collaboration. Today, CPG provides strategic guidance to industry partners looking to reduce their carbon footprint.

“Our rich experience and multidisciplinary capabilities enable

us to engage in all building lifecycle phases, providing a holistic view of carbon across the entire value chain. By focusing on whole life carbon, we believe effective decarbonisation should reduce emissions at every stage, from pre-design to end of life. Our expertise ensures that businesses can navigate the complexities of carbon management effectively and sustainably,” says Mr Tan Shao Yen, CPG’s President and Group Chief Executive Officer.

Last year, CPG published ‘Embodying Sustainability – A Decarbonisation Playbook for the Built Environment’, a framework supporting holistic decarbonisation strategies that help clients understand regulatory requirements, set ambitious yet achievable carbon reduction targets and develop comprehensive decarbonisation roadmaps.

Looking ahead, CPG remains committed to driving meaningful change by sharing its expertise, fostering industry collaboration and advocating for a more sustainable, decarbonised future.

A call to action for engineers

Embracing sustainability is a necessity.

Climate change is no longer a distant threat. It is a present reality. Across the globe, its impact can be felt, daily, from scorching heatwaves and devastating storms to increasingly erratic weather patterns.

Singapore, too, has experienced its share of anomalies, with record-breaking temperatures and unpredictable bouts of intense rainfall and flooding. The writing is on the wall. Embracing sustainability in all aspects of life is not just an option, it is a necessity. And engineers, the builders of our world, must be at the forefront of this transformation.

For too long, sustainability considerations have not been prioritised within the engineering profession. Engineers, by nature, are often inclined towards overdesign, prioritising safety factors above all else. The traditional approach often favours building, tearing down and rebuilding – a cycle that consumes vast resources.

Redundancy is often a key design principle and design methods frequently rely on rules of thumb rather than modern, computationally driven solutions. While these practices have served engineers in the past, they are fundamentally incompatible with a sustainable future.

With climate change now posing an existential threat to humanity, engineers must fundamentally shift their thinking. They must move beyond a purely functional approach and embrace sustainability in every facet of the projects. This requires a paradigm shift – a move away from the ‘build first, consider later’ mentality to one where sustainability is embedded from the initial concept stage.

This means questioning

It is the responsibility of engineers to build a sustainable future.

traditional design principles:

• Can we achieve the necessary safety margins with less material?

• Can we design for adaptability and reuse, rather than demolition and reconstruction?

• Can we leverage advanced computational tools to optimise designs for both performance and resource efficiency?

These are the questions that must be asked.

The Singapore Exchange (SGX) has played a pivotal role in shaping the sustainability reporting landscape. Since the introduction of the ‘comply or explain’ mandate in 2016, listed companies have been required to disclose their sustainability practices, adhering to internationally recognised frameworks like the Global Reporting Initiative (GRI) and the Sustainability Accounting Standards Board (SASB).

This push for standardisation has enabled stakeholders to make informed decisions, based on comparable and consistent data. However, reporting is just the first step. True sustainability must be ingrained in the engineering DNA.

The challenges are significant. Many businesses, particularly small

and medium-sized enterprises (SMEs), struggle with data collection and verification, due to limited resources and expertise.

The complexity and costs associated with implementing comprehensive reporting frameworks can be daunting. Furthermore, the risk of greenwashing necessitates stronger enforcement mechanisms to ensure genuine commitment. Finally, balancing comprehensive disclosures with business confidentiality remains a delicate act.

The road ahead requires a multipronged approach. Strengthening regulations, capacity building, leveraging technology, encouraging integrated reporting and fostering public-private partnerships are all crucial. But most importantly, there must be a change in mindset, within the engineering profession itself.

Engineering companies must recognise that embedding sustainability into the business model is not just an option – it is a strategic imperative. They should be committed to change, embracing the challenge head-on.

Engineering companies can turn sustainability requirements into opportunities for growth.

This is not just about meeting regulatory requirements.

• It is about recognising the responsibility, as engineers, to build a sustainable future.

• It is about moving beyond traditional practices and embracing innovation.

•It is about working towards a new era of climate action, where engineering expertise is harnessed to create a world that is both functional and sustainable.

The time for incremental change is over. The time for bold action is now!

This enabled the office towers to obtain the Green Mark Platinum certification.

A BCA Learning Journey, co-organised with APM, demonstrated the strategies adopted by APM for the decarbonisation of 61 Robinson, that enabled the building to obtain the Green Mark Platinum certification from a Green Mark Gold rating, with zero Capex.

How energy innovation is transforming manufacturing

A facility in Singapore significantly slashed its carbon emissions, without compromising productivity.

Meeting complex energy demands in pharmaceuticals

When a leading, global pharmaceutical company set out to build a stateof-the-art manufacturing facility in Singapore, it encountered dual challenges – how to power specialised equipment while meeting ambitious environmental targets.

To address this, the company turned to ENGIE, a leader in lowcarbon energy solutions. Leveraging its expertise in sustainable manufacturing practices, ENGIE implemented a Central Utilities Building (CUB) to manage seven essential utilities, including steam, chilled water and compressed air. Operated through a Utilities-asa-Service (UaaS) model, the CUB seamlessly integrates sustainability into every stage, from design to implementation, showcasing the impact of tailored energy solutions.

This greenfield project exemplifies a growing trend in manufacturing – integrating sustainability into facilities from the start, to meet rising investor and consumer expectations for environmental responsibility. Using advanced technologies like magnetic bearing chillers and heat recovery systems, the facility avoids over 9,000 tonnes of CO₂ emissions. These efficiencies demonstrate how new facilities can achieve significant environmental impact from day one.

Accelerating sustainability through regulatory drivers

Southeast Asia’s regulatory frameworks are accelerating the shift towards sustainable practices. In Singapore, its progressively rising Carbon Tax – from SGD 5 to SGD 25 per tonne by 2024 and 2025 – and mandatory climate-related financial disclosures are reshaping

investment decisions.

For energy managers ready to lead the charge, the message is clear. Innovation and sustainability are not just compatible, they are the foundation for a resilient future.

Sustainably and efficiently decarbonising manufacturing SMEs in Singapore

by Prof Lock Kai Sang and Dr Deepak L Waikar, Energy Efficiency Technology Centre, Singapore Institute of Technology

Energy assessments lead to lower energy bills, improved business competitiveness and a reduced environmental footprint.

Energy efficiency plays a pivotal role in sustainability, particularly for Manufacturing Small and Medium Enterprises (MSMEs) in Singapore. For MSMEs, systematic energy efficiency measures translate to lower energy bills, improved competitiveness and a reduced environmental footprint. According to the International Energy Agency (IEA) [1], energy efficiency improvements could contribute to more than 40% of the emissions reductions needed to meet global climate goals by 2040.

Singapore has implemented various initiatives to enhance energy efficiency in the manufacturing sector. The Energy Efficiency Grant (EEG), previously Energy Efficiency Fund (E2F), administered by the National Environment Agency (NEA), supports MSMEs in adopting innovative energy-efficient technologies, processes and solutions.

The Energy Efficiency Technology Centre (EETC) of the Singapore Institute of Technology (SIT), in collaboration with the NEA, has systematically performed energy assessment for 225 significant energy-using industrial systems, such as compressed air systems, boilers, pumps, motors, lighting and HVAC, used by MSMEs in Singapore, since February 2021. Such ISO 50002 Energy Management Standard level assessments led to an estimated annual energy savings of 17.6 million kWh, an annual carbon abatement of 7.4 million kgCo2e, and SGD 3.0 million savings in annual energy bills.

For example, optimisation in one of the Food MSMEs, having 14 dryers, resulted in an annual energy savings of 290,000 kWh and an annual carbon abatement of 120,000 kgCo2e. Similarly, the implementation of energyefficient lighting and HVAC systems achieved a 20% reduction in energy consumption [2], for one of the precision engineering MSMEs, and the adoption of an energy management system [2] achieved a 30% reduction in energy usage for another MSME.

Such examples testify to how systematic energy assessment can contribute to energy savings and decarbonisation for MSMEs.

To sustain the momentum, one of the crucial aspects of the service to MSMEs is the upskilling of engineers, technologists and managers in the energy efficiency domain. Over 400 such professionals were trained from June 2020 to December 2024, as a result of collaborative efforts between NEA, EETC-SIT and SSG.

In addition, 85 undergraduate students benefitted from the Integrated Work Study Programme (IWSP), through hands-on involvement in the energy assessment of MSMEs under the supervision of energy specialists from EETC-SIT.

SIT offers a sustainability learning roadmap for undergraduates and working professionals. In it, EETC plays a key role especially in the energy aspect of sustainability.

Sustainability education in SIT covers Pre-employment Training (PET), with strategies that build

a strong foundation to prepare learners for advanced, crossdisciplinary sustainability topics and projects; and deepen sustainability knowledge through integrated core and discipline-specific modules on key topics such as life cycle assessment and green financing.

Working professionals can supercharge sustainability knowledge through Continuing Education and Training (CET) and workshops that stack to a Specialist/Graduate Certificate.

The ASEAN Plan [3] of Action for Energy Cooperation (APAEC) 20162025 outlines a comprehensive strategy to enhance energy efficiency and conservation across the region. This includes setting energy intensity reduction targets and promoting energy-efficient technologies and practices. NEA, EETC-SIT, and other industry stakeholders can collaborate to take advantage of the opportunities within the ASEAN region.

It can be concluded that managing energy consumption through systematic energy assessment and efficiency measures can lead to the sustainability and decarbonisation of MSMEs in Singapore.

Understanding EPDs for HVAC

by Yeo Wei Liam, Managing Director, Systemair and Hannah Jouy, Marketing Consultant, Systemair

They are important in advancing sustainable construction practices.

Today’s sustainability in the built environment has evolved beyond energy efficiency to encompass over 20 environmental factors, including material efficiency, CO₂ emissions and the Global Warming Potential (GWP). These complexities are evaluated through lifecycle assessments (LCAs) and verified via Environmental Product Declarations (EPDs). As sustainability reporting laws worldwide grow stricter, the demand for EPDs is surging, raising the question, “What are EPDs, and how should they be interpreted?” At its core, LCAs comprehensively assess a product’s environmental impacts throughout its lifecycle. At the same time, EPDs certify these evaluations, offering vital environmental information about materials and components used in construction. While EPDs for traditional materials have been available for years, their scope has expanded to encompass technical equipment and HVAC products. This shift is crucial, as ventilation systems influence indoor air quality (IAQ) and energy consumption.

EPDs are gaining global traction, as national building codes increasingly mandate LCAs for new buildings. Organisations like the Singapore Green Building Council are highlighting their importance and EPDs also contribute valuable credits to green building certifications such as BREEAM and LEED.

Breaking it down

All LCAs in the construction sector adhere to the same structure, whether for individual products or entire buildings, as defined by the most globally recognised standard, EN 15804 (Sustainability of construction works – Environmental Product Declarations). EPDs communicate ‘verifiable, accurate,

non-misleading environmental information’, through the following lifecycle stages:

• Production: Raw materials, transport, and manufacturing.

• Construction: Transport and installation processes.

• Use: Maintenance, repair, replacement, refurbishment, and resource consumption.

• End-of-Life: Deconstruction, demolition, waste processing, and disposal.

• After-Life Benefits: Potential for reuse, recovery or recycling. These stages are categorised into three types of EPDs:

• Cradle-to-Gate: Covers production and end-of-life stages.

• Cradle-to-Gate Plus Options: Includes additional construction and use stages.

• Cradle-to-Grave: Encompasses all five stages.

Systemair adheres to globally recognised standards to ensure accurate and transparent EPDs. The company’s EPDs typically follow a Cradle-to-Gate model, reflecting what is generally applicable across all projects. As operational energy use varies significantly, depending on project-specific factors such as airflow, pressure, climatic conditions and local energy sources, these variations make it impractical to generalise energy use within EPDs.

Product selection tools and lifecycle cost calculators address this variability, enabling project-specific energy performance assessments. This helps stakeholders make informed decisions that align with their sustainability goals.

As LCAs become mandatory in building projects, EPDs play a pivotal role in ensuring accurate environmental assessments and are critical in choosing the right solution for a project. For example, Systemair EPDs, compliant with EN 15804, ISO 14025 and ISO 14040/14044 standards, are published on the company’s website and verified by the Norwegian EPD Foundation, which is a member of the ECO Platform, making our EPDs globally recognisable.

In total, these EPDs cover tens of thousands of item numbers. Examples include the MUB EC fans and air curtain series like Pamir and Arden. These certifications support sustainable construction globally, reinforcing the importance of integrating EPDs into every building lifecycle phase.

As the demand for sustainable practices continues to rise, EPDs play a pivotal role in driving compliance, fostering innovation and ensuring quality ventilation. Together, these efforts pave the way for a more sustainable future in the built environment.

The scope for EPDs now encompasses technical equipment and HVAC products.

The future of EC fan technology

Revolutionising energy efficiency.

In Singapore’s older buildings, many fans use AC motors, resulting in high energy consumption. Retrofitting with EC fans offers a quick solution. While most energyefficient buildings have already switched to EC fans for their HVAC systems, energy consumption can be further optimised by upgrading to the latest EC fans with integrated Active PFC (Power Factor Correction) and IoT-enabled smart ventilation.

The next generation of advanced EC technology products includes super-efficient motors with higher power density, enhanced control algorithms, integrated Active PFC and sensors.

The latest EC fan models will increasingly be connected to IoT platforms, incorporating machine learning for predictive analytics and adaptive control, enabling real-time adjustments to optimise performance. These EC fan models will utilise eco-friendly materials and are designed to minimise both energy consumption and waste.

Key benefits of Active PFC in energy efficiency

Active PFC plays a crucial role in enhancing the energy efficiency of EC fans. By correcting the phase difference between current and voltage, Active PFC improves the power factor, bringing it closer to 1.0. This ensures that the fan consumes power more efficiently, reducing wasted energy.

Another key benefit is harmonic reduction. Active PFC minimises current and voltage distortion in switching power supplies, which can disrupt the power supply. In some of the more advanced EC fan models with integrated Active PFC, <5% Total Harmonic Distortion (THDI), down to 10% of their power draw, can be achieved, even in disturbed power supplies, without

requiring adjustments onsite during installation.

By smoothing out distortions, integrated Active PFC ensures a stable, high-quality power supply which prevents overheating, energy disruptions and electrical noise, thus improving overall system efficiency. In the long run, Active PFC extends the lifespan of electrical equipment by reducing wear and tear, leading to lower maintenance costs and reduced utility and operating expenses.

Unlocking digital sustainability with IoT

Smart Ventilation Systems, powered by IoT, are at the forefront of the transformation of building management. These systems use IoT technology to monitor and regulate indoor air quality in real time. They adjust ventilation rates based on occupancy levels, outdoor air conditions and other

environmental factors, ensuring optimal indoor air quality while minimising energy consumption. The integration of these IoTenabled systems with Building Management Systems (BMS) represents a significant step forward. Enhanced connectivity allows for centralised control of HVAC systems, facilitating proactive maintenance and optimising operational efficiency. This integration improves overall building management, ensuring that energy usage is always balanced with occupant needs.

Smart ventilation systems are shaping the future of sustainable indoor spaces by enhancing air quality, energy efficiency and comfort, while integrating with modern building management.

The combination of Active PFC, IoT connectivity and next-gen EC technology drives eco-friendly, energy-efficient solutions for a greener future.

Active PFC enhances the energy efficiency of EC fans.

REASONS TO MONITOR

YOUR INDOOR AIR QUALITY

According to the World Green Building Council, we spend 90 percent of our time indoors. Given that statistic, it’s clear the quality of the air we breathe in buildings can dramatically impact our health and well-being. At Reliable Controls we believe sustainable buildings are a key component to reducing the health and environmental impacts of indoor and outdoor air pollution.

1

Improve comfort and productivity.

Research from the US Environmental Protection Agency (EPA), informs us that indoor air contains two to five times more volatile organic compounds than outdoor air due to chemicals found in buildings. This impacts human health, from eye and throat irritation to respiratory diseases and cancer.

And while you can’t yet monitor the presence of a virus like COVID-19 in the air, you can measure a number of factors that affect the risk of viral transmission: temperature, humidity, and CO2. These air-quality measures are also linked to workplace well-being and productivity, so the better the air in your building, the better your occupants are likely to feel—and perform.

2

Save energy.

Excessive ventilation wastes energy. Ideally, a building’s ventilation system provides just the right amount of air. Many ventilation systems, especially older ones, are based on constant air volume, which means they always operate at full capacity. By converting to a variable air volume system, you can optimize your energy efficiency with demand-controlled ventilation. The EPA found that a ventilation upgrade from constant air volume to variable air volume can achieve annual energy savings of 10 to 21 percent. Beyond that, with air-quality sensors, you have access to real-time data that informs when and where to efficiently deploy air filtration and temperature control.

Integrating IAQ sensing technology into your building automation system means you can collect building data that helps you perform preventative maintenance and avoid system failures. By tracking pollutant levels continuously over time, for example, you can easily identify where and when to address changes in air-quality parameters. Long-term trends are almost impossible to detect with periodic spot sampling, which provides only a snapshot of data points at a particular time.

Most people know IAQ sensors can warn building managers about safety issues like smoke or carbon monoxide. Did you know they can also tell you how much particulate matter is in the air? Or how many harmful volatile organic compounds are circulating in your space? IAQ data can help you determine where to focus cleaning, when to service equipment, when to change filters, and when to increase or decrease ventilation.

Earn building certifications.

IAQ monitoring is a crucial component in healthy building certifications like NABERS. To earn an Indoor Environment (IE) star rating under NABERS v2, for example, a facility must meet a minimum IAQ requirement intended to benefit occupants, maintain ventilation system equipment, and follow guidelines for mechanically and naturally ventilated spaces, in addition to other measures of indoor comfort.

From regularisation to revelation

by Stephen Huong and Er. Cavan Chai, CVC Engineers Pte Ltd

The unexpected journey into sustainability.

The journey of CVC Engineers began with a seemingly simple mission – to assist building owners in navigating the complex world of unauthorised structures. In the early days, we were primarily motivated by a desire to assist owners whose unauthorised structures had been flagged by local authorities.

Typically, when such buildings were flagged, some building owners assumed they had to remove them immediately to avoid further scrutiny, while those who realised they could rectify the issue through proper submissions, often struggled to find a Professional Engineer willing to undertake the tedious regularisation process.

We also realised that many of these cases were not born out of a deliberate attempt to flout the law. Often, owners were genuinely unaware that the renovations, perhaps inherited from previous owners, or carried out by contractors without proper oversight, were in violation of building regulations. We viewed these challenges as opportunities, rather than obstacles, in the early stages of our business.

As we immersed ourselves in the technical intricacies of regularisation, a surprising realisation began to dawn on us. Our work, initially focused on legal compliance, was having an unintended but profoundly positive environmental impact. By preventing unnecessary teardowns, we were, in effect, reducing the consumption of new construction materials and curtailing the generation of construction waste. This revelation transformed our perspective. What began as a niche service, focused on navigating building regulations, evolved into a passionate commitment to

sustainability.

The environmental benefits of regularisation, particularly in terms of waste reduction, are significant and often underappreciated. Every time we successfully regularise a structure, we prevent a cascade of environmental consequences. Take, for instance, the materials typically involved in even a modest, unauthorised addition – concrete and steel.

Our data at CVC Engineers indicates that, on average, each regularisation project we undertake saves approximately 1.5 tonnes of steel and 0.2 tonnes of concrete, from being needlessly discarded.

Considering that the Building and Construction Authority (BCA) in Singapore handles an average of 120 cases of unauthorised structures annually, the potential for waste reduction through widespread regularisation is immense.

To add context, the production of one tonne of steel generates about 1.85 tonnes of CO2, while producing one tonne of cement (a key ingredient in concrete) results in approximately 0.9 tonnes of CO2 emissions. Thus, even seemingly small amounts of saved steel and concrete translate into meaningful

reductions in carbon emissions.

These figures, moreover, highlight the untapped potential of regularisation as a powerful tool for waste reduction. It is important to remember that many unauthorised structures are currently demolished not because they are inherently unsafe or unsalvageable, but because building owners are unaware of the regularisation option or find the process too daunting.

Furthermore, the demolition process itself is far from being environmentally neutral. It is an energy-intensive undertaking that involves significant manpower, the deployment of heavy machinery like excavators and the transportation of debris to landfills, often located far from urban centres.

The demolition of illegal structures generates a wide array of waste types, including nonrecyclable and hazardous materials that strain waste management systems. In Singapore, the median cost of demolishing an average residential structure can soar to SGD 150,000, a figure that underscores the economic inefficiency of demolition, not to mention the valuable man-hours

lost in an unproductive endeavour.

All of this activity contributes to a significant carbon footprint –from the fuel consumed by excavators and transport vehicles to the energy required for waste processing. Regularising structures reduces the need for these frequent, energy-consuming demolitions and reconstructions. The best way to manage demolition waste is to prevent its creation, in the first place.

Today, we at CVC Engineers see an even more noble reason to champion our cause in this niche market. We believe that the issue of unauthorised structures and their environmental impact could be addressed far more effectively through broader awareness.

This is where the Institution of Engineers, Singapore (IES) and the wider engineering community can play a vital role. As civil engineers, we are subject matter experts who can educate consumers, policymakers and fellow professionals about the true costs of demolition and the tangible benefits of regularisation. Engineers are best positioned to explain the technicalities, quantify the environmental impact and advocate for a more sustainable approach to managing the built environment.

While educating building owners on building regulations and frequent building inspections focuses on the prevention of cases of unauthorised building constructions, our efforts, on the other hand, cater to the need to promote sustainability, by promoting a regularisation process for previously completed unauthorised structures.

We need to champion a paradigm shift within the industry, moving away from a default position of demolition towards one that prioritises regularisation as a sustainable practice, when structures already exist and are found to be unauthorised.

Our journey has been one of unexpected discovery. From a focus on regulatory compliance, we have

stumbled upon a powerful truth – that seemingly small actions, like choosing regularisation over demolition, can have a profound impact on our environment.

As we move forward, CVC Engineers remains committed to not only providing expert regularisation services but also to raising awareness about the crucial link between this niche area of our work and the broader goal of building a more sustainable future. By sharing our knowledge and advocating for change, we hope to inspire a shift in the industry, where every building, authorised or otherwise, is viewed not just in terms of its immediate function but also in terms of its long-term environmental footprint.

When an unauthorised structure is discovered, the automatic response should not be towards immediate demolition. Instead, we advocate a careful consideration of

regularisation as the first option. While we fully support upholding building regulations and ensuring accountability, we also believe that the environment deserves equal consideration.

Even in cases of intentional violations, the environmental cost of demolition should be weighed against the potential benefits of regularisation. Choosing regularisation, whenever feasible, is not about circumventing justice, it is about recognising that a win for the environment can also be a win for responsible development.

It is about finding a solution that minimises unnecessary waste and promotes a more sustainable approach to managing our built environment. We believe that regularisation, often perceived as a tedious bureaucratic process can, in fact, be a powerful tool for building a more sustainable world – one structure at a time.

Demolition is energy-intensive and produces a wide array of waste types including non-recyclable waste and hazardous materials.

Regularising unauthorised structures is an environment-friendly option.

The 8th edition of the Mapei Group’s Sustainability Report has now been published. It is the second time that the report covers all the countries in which it operates. The Group’s guidelines include attention to the environment, people and the planet.

Mapei is continuing to grow across all five continents and is keen to guide the market towards increasingly ethical and responsible decision-making. It is with this in mind that the company has published its eighth Sustainability Report, the second time it is covering all 57 countries in which it operates.

Putting its great experience and constant commitment to research to good use, Mapei set new and significant goals in 2023 – the year when it exceeded 4 billion Euros in revenue as it continued to set the standard in the building industry.

“This eighth edition of the Sustainability Report once again confirms our commitment and desire to ensure human rights and good working conditions. The principles of equal opportunities, diversity and inclusion are respected in all our operations,” said Veronica Squinzi, Mapei Group CEO.

Sustainability remains a core value. New Environmental Product Declarations (EPDs) covering Mapei products were published in 2023, reaching a total of 190 EPDs at the Group level. This is a constantly growing number. Today, there are 330 EPDs for Mapei products.

The residual CO2 emission offsetting project was also extended to all Mapei subsidiaries.

Today, Mapei has 230 Zero products, including building mortars, waterproofing materials, paints, cleaning products and ceramic/stone installation products.

“A number destined to increase over time to encompass complete installation systems,” added Marco Squinzi, Mapei Group CEO.

The company also continued to implement energy efficiency measures at numerous manufacturing sites worldwide,

with several Mapei subsidiaries installing photovoltaic systems in their facilities, including subsidiaries in Poland, Bulgaria, Malaysia and Hungary.

Considerable attention is also paid to environmental impact, thanks to the RE-CON line solutions which enable concrete producers to reduce both their environmental impact and waste handling costs. By transforming waste streams like returned concrete and cementitious residues in trucks into recyclable aggregates, a more circular and cost-effective production model can be achieved.

Training is also at the heart of Mapei’s corporate strategy. It is viewed as capital to be cultivated with dedication and commitment both for the company’s own staff –now more than 12,500 worldwide – and for all professionals working in the industry. The Mapei Academy enabled the Group to get around 290,000 people involved

in its training activities in 2023, corresponding to a total of 52,609 hours of technical training on a global level.

A case study of sustainability certification for constructional steels

by Lee Brankley, Ayhan Tugrul, Ladin Camci, Chin Seng Yap and David Knight at CARES Certification Pte Ltd

The concept of ‘extended’ product responsibility is applied to reinforcing steel.

Constructional steels are a key part of any major construction project and are often used to reinforce concrete construction systems. Its supply chain covers raw material sourcing and steel manufacture, distribution, fabrication and delivery to a construction site.

The CARES Sustainable Constructional Steel (SCS) scheme, initially set up in 2012, applies to primary producers of constructional steels and fabricators who process steel into building products used in construction projects, such as steel reinforcement used for structural concrete beams, columns and slabs.

The scheme aims to deliver improved sustainability and resilience in the construction sector by providing assurance to construction product buyers that sound sustainability management practices are in place throughout their steel supply chain. The principles of inclusivity, integrity, stewardship and transparency provide the basis for the scheme. It also provides full traceability, to the source of key raw materials such as steel scrap, and product information is available via the CARES Cloud digital product passport.

It also provides a way for suppliers to clearly demonstrate sustainability management practice and outcomes. The scheme criteria include a rating system – the CARES Rosette Rating System – enabling producers to differentiate their performance against their peers, and buyers to benchmark their suppliers.

The SCS scheme is accredited to BS 8902 (Responsible Sourcing Sector Certification Schemes for Construction Products) by the United

Kingdom Accreditation Service and is recognised by BREEAM, the Singapore Green Building Council (SGBC) and other building rating systems. A company-specific verified Environmental Product Declaration (EPD) to EN 15804 is a requirement.

The concept of extended product responsibility can be used to illustrate the demands placed upon a modern construction material supply chain.

The product's core benefit is the reinforcement of concrete within a construction project. Around the core are other attributes relating to that product’s performance, e.g. strength and ductility. These are stated in a product standard, e.g. BS 4449, and constitute the ‘specified product’.

All companies in the CARESapproved supply chain must have an environmental management system certified to ISO 14001,

a quality management system certified to ISO 9001, an occupational health and safety management system certified to ISO 45001, a traceability mechanism, and an independently verified EPD to EN 15804. Beyond the physical product, buyers are increasingly making purchasing decisions based on the broader impacts of its supply chain.

The concept of ‘Materiality’– the issues and impacts that are most significant and relevant to the organisation and its stakeholders along the entire value chain – is used to inform the selection and prioritisation of impacts. Companies must demonstrate effective management of these and improved performance.

Finally, the steel supply chain is informed by the inclusion and consideration of a wide range of stakeholder opinion.

Pioneering circular aluminum hoarding system solutions for commercial spaces

Ensuring sustainability and aesthetics.

In the dynamic retail landscape of Singapore, shopping malls frequently undergo renovations to stay competitive and meet evolving consumer demands. During these transitions, temporary interior hoarding – the barriers used to section off construction areas –plays a vital role. The choice of material can make a significant difference in both the sustainability and aesthetics of the hoarding.

Traditional materials like plywood and gypsum panels, commonly used for interior hoarding, pose significant environmental challenges. Addressing these issues, R3 Systems Pte Ltd has introduced circular aluminum hoarding as a transformative solution, tailored to the unique needs of shopping malls.

The case for aluminum hoarding in shopping malls

When shopping malls undergo renovations, hoarding plays a crucial role in ensuring safety and maintaining order. Traditionally, materials like plywood and gypsum boards have been used. Over time, plywood, being combustible, has been increasingly replaced by gypsum boards to meet local fire safety regulations.

While gypsum is non-combustible, it creates a significant environmental challenge. Renovation waste from gypsum boards cannot be reused, leading to substantial landfill contributions and escalating disposal challenges. This also drives up operational costs for businesses.

Aluminum hoarding offers a revolutionary alternative. Known as the ‘green metal’, aluminum can be recycled endlessly without compromising its strength or quality. By adopting aluminum hoarding, malls can reduce renovation waste produced by hoarding, by

up to 90%, eliminate reliance on harmful materials, and embrace a sustainable, cost-effective and environmentally friendly solution.

“The aluminium hoarding advantage is based on sustainability, circularity and aesthetics. Aluminum is one of the most versatile materials we work with, and its reusability is at the heart of our hoarding systems. Our panels are designed to be reused multiple times across various applications, from mall renovations and elevator enclosures to crowd guidance systems, corporate events and even as temporary advertising spaces,” said a representative of R3 Systems Pte Ltd.

“Our approach focuses on maximising the lifespan of each panel. Instead of using single-use materials that end up in landfills, our system can be redeployed repeatedly, delivering exceptional value and significantly reducing environmental impact,” the representative added.

Furthermore, non-combustible aluminum enhances fire safety within confined mall spaces. Panels can be printed with branding or promotional messages, maintaining the mall’s visual appeal.

In addition, R3 Systems Pte Ltd’s aluminum hoarding system is freestanding and is engineered to meet rigorous standards.

The system incorporates structural

reinforcements that provide high stability, ensuring protection for shopping mall finishes. This design prevents damage to architectural elements while maintaining structural integrity throughout its use.

Lastly, the sleek and customisable design seamlessly integrates into upscale environments, preserving the visual appeal and sophistication expected by discerning clientele. This makes R3 Systems Pte Ltd’s solution particularly valuable for high-end retail spaces.

Driving sustainability in retail spaces

Beyond aesthetics and safety, R3 Systems Pte Ltd is paving the way for greener retail environments. This commitment to reusability aligns with Singapore’s Green Plan 2030, emphasising waste reduction and circular economy practices.

By adopting R3 Systems Pte Ltd’s circular aluminum hoarding, malls can significantly reduce waste, support decarbonisation efforts in retail construction and take a meaningful step towards sustainability. As retail spaces evolve, circular aluminum hoardings are emerging as a superior replacement for conventional solutions, demonstrating how shopping malls can align operational efficiency with environmental responsibility.

Towards sustainable fire protection

by Kenny Lee, Director, Archer (S) Pte Ltd

Overcoming the challenges of transitioning to PFAS-free foam.

Across multiple industries – ranging from petrochemicals and aviation to power generation – firefighting foam remains a critical safeguard against catastrophic incidents.

Historically, Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foam (AFFF) and FilmForming FluoroProtein Foam (FFFP) have provided rapid fire knockdown, thanks to fluorosurfactants that drastically lower the surface tension of water. This action allows a thermally stable aqueous film to form on top of the fuel, effectively sealing vapours and aiding quick extinguishment.

Today, growing environmental and health concerns around PFAS persistence have accelerated a global shift toward Synthetic Fluorine-Free Foam (SFFF). As part of this movement, Singapore –also a signatory to the Stockholm Convention – has enacted new regulations to tighten the import, use and storage of PFAS-based foam concentrates.

Unlike fluorinated formulations, SFFF typically relies on hydrocarbonbased surfactants, which cannot form a continuous aqueous film. Instead, these foams depend on a robust and cohesive bubble structure to suppress fires. This distinction represents a complete paradigm shift in firefighting tactics and system design, especially against large-scale or complex fuel hazards.

Different classes of fuels – even in hydrocarbon (non-polar solvent) fires – can affect how effectively SFFF blankets the hazard, requiring more precise application rates, density calculations and adjusted discharge methods. The latest Factory Mutual standards already reflect these refinements, and further updates are likely in other

Engineered piping and valves form the backbone of any foam-based fire protection system and require careful calibration and maintenance to support the shift to fluorine-free agents.

design and type-approval guidelines. Transitioning to SFFF, therefore, requires far more than a product swap. In many cases, existing foam proportioners, discharge nozzles and piping systems must be reengineered to ensure they deliver the correct flow rate and foam consistency.

Additionally, thorough system decontamination is vital. Residual PFAS in tanks, hoses or pipe networks can compromise new foam concentrates, leading to cross-contamination and potential regulatory non-compliance. Dedicated decontamination protocols – flushing, cleaning, and replacing incompatible components – help ensure that SFFF systems operate at their designed effectiveness without trace remnants of fluorinated compounds.

Equally important is performance validation. Full-scale fire tests, sometimes conducted under conditions that simulate realworld hazards, confirm that new SFFF systems meet recognised standards. These tests also build operator confidence, especially when dealing with fuels that behave differently with fluorinefree agents. On the human side,

Firefighters conducting live exercises to ensure that fluorine-free foams match the performance and reliability once provided by traditional PFAS-based products.

firefighters and emergency responders need updated training to adapt to SFFF’s particular foam characteristics, including coverage patterns and extinguishment rates.

Despite these challenges, the shift to fluorine-free solutions signifies a broader commitment to sustainable development. As more industrial facilities take on the technical and operational nuances of SFFF, the industry is gathering critical data that will continue to inform best practices.

Specialist consultancies, such as Archer, which have supported multiple large-scale conversions, emphasise a partnership model that brings together end-users, foam manufacturers and regulatory bodies.

A sustainable modern polymer derived from plants

Made from castor oil, Rilsan® Polyamide 11 has many industrial applications.

Before the advent of synthetic polymers, humans relied on a variety of natural materials for their needs. Some of the most commonly used materials include wood, metal, natural rubber, glass and leather. This changed in 1907, when a fully synthetic, fossil-based plastic called Bakelite was invented. It marked the beginning of the modern era of plastics, leading to the development of a wide variety of synthetic polymers that replaced most materials used before the 20th century.

While versatile, this relatively new material presents a complex issue with regard to sustainability. While plastics offer many benefits, such as durability and versatility, they pose significant environmental challenges. Derived from fossil fuels, their production can be energy-intensive and contributes to greenhouse gas emissions, resource depletion and the loss of natural habitats.

Rilsan® Polyamide 11 (PA11) from Arkema is a class of polymer that is looking to change all of these issues.

Rilsan® PA 11 is derived from the oil of castor seeds. Each castor seed contains approximately 50% oil and, under optimal conditions, the oil extraction process can yield around 35% to 50% oil. The remaining pulp, known as castor cake, is also not wasted. This byproduct is typically made into fertiliser, animal feed, or becomes a fuel in a biogas plant.

Unlike other forms of plantderived oils, the castor plant exhibits several qualities that amplify its sustainability credentials. It is naturally droughtresistant and thrives in climates and lands too poor for agricultural use. Since it grows on land too poor for most vegetation, it does not contribute to deforestation. There

is no competition with human or animal food production.

As a result, it is deemed a low-risk crop with a favourable sustainability profile, by the Solar Impulse Foundation.

In the Rilsan®PA 11 production chain, Arkema uses bio-based raw materials coming from the castor plant. This contributes to reduced carbon emissions compared to fossil-based polyamides.

In January 2023, Arkema also signed an agreement for 300 GWh/ year of renewable biomethane energy supply with ENGIE, further reducing the carbon footprint of its bio-based materials. The carbon footprint is now 70% lower than traditional fossil-based polyamides. Through the adoption of renewable energy sources, this carbon footprint is expected to become 80% lower than traditional fossilbased polyamides in 2025.

Besides being sustainable, Rilsan® PA 11 exhibits impressive physical characteristics. It is lightweight, resistant to many chemical classes, tough and dimensionally stable. These properties make it versatile across multiple industries. Its durability

and chemical resistance make it a good candidate for automotive and other transportation applications, including in fuel lines, brake lining and air conditioning systems.

Additionally, its corrosionresistant properties make Rilsan® PA 11 coatings ideal for products used in fluid transfer solutions, like pipes, fittings and valves used in oil & gas applications, and also for drinking water systems, since they meet the required specifications.

Sustainability development in the safety equipment industry

A growing trend.

The safety equipment industry is increasingly recognising the importance of sustainability in its operations and product offerings. This shift is driven by a growing awareness of environmental concerns, evolving consumer expectations and the potential for innovation and cost savings.

Environmental concerns, such as climate change and resource depletion, are no longer distant threats but present realities that are impacting businesses and consumers alike. The safety equipment industry, as a significant contributor to industrial activity, is recognising its responsibility to minimise its environmental footprint and contribute to a more sustainable future.

This recognition is further amplified by the evolving expectations of consumers, who are increasingly demanding products and services that are not only safe and effective but also environmentally responsible.

Manufacturers are increasingly incorporating recycled and renewable materials into their products, such as recycled plastics and bio-based alternatives. Minimising the use of hazardous chemicals and substances throughout the manufacturing process is a crucial aspect of sustainable production.

Ensuring that materials and components are sourced ethically and responsibly throughout the supply chain is crucial. Optimising transportation routes and utilising eco-friendly transportation methods can minimise the environmental impact of logistics.

To support its customers in their sustainability goals, the uvex safety group, from Germany, has initiated carbon footprinting across its entire

supply chain.

This involves calculating the total greenhouse gas emissions associated with the production and use of the group’s safety products. By providing this transparent data, the uvex safety group enables customers to gain a comprehensive understanding of their own carbon footprint and identify opportunities to reduce their environmental impact. This data is essential for achieving the climate neutrality targets set forth in the European Green Deal.

Examples of the sustainable safety products include the uvex pheos planet safety helmet, part of the uvex ‘protecting planet’ sustainable product line. Crafted with up to 30% bioplastic derived from sugar cane and a headband incorporating 50% recycled helmet shell material, this helmet minimises waste.

Its packaging, made from recycled materials, and user instructions printed on 100% recycled paper, further demonstrate the uvex safety group’s commitment to sustainability.

The patented uvex Bamboo TwinFlex technology in the 18-gauge Cut Level D glove ensures a combination of wearer comfort and high-level cut and abrasion resistance. It features sustainable materials like bamboo-viscose and recycled polyamide.

However, challenges remain in integrating sustainability into the safety equipment industry, including balancing sustainability with performance, raising consumer awareness and fostering collaboration across the value chain.

However, these challenges also present opportunities, allowing the industry to capitalise on the growing demand for sustainable solutions.

The use of bioplastics and recycled material has enabled the uvex safety group to reduce the carbon footprint of a uvex pheos planet B-WR safety helmet to 1.99 kg CO₂e (Calculation date: 07/2024) in the cradle to customer calculation.

Due to the use of sustainable materials, the carbon footprint of a pair of uvex Bamboo TwinFlex D xg planet gloves has been reduced to 0.47 kg CO₂e (Calculation date: 04/2024) in the cradle to customer calculation.

In conclusion, sustainable development transcends the realm of environmental stewardship, emerging as a critical imperative for economic and social progress. It necessitates a holistic approach that considers the interconnectedness of environmental, social and economic factors.

By embracing sustainability as a core principle, one can not only contribute to a healthier planet and a safer workforce but also unlock significant opportunities for innovation, efficiency and long-term prosperity.

Each module is credit-bearing and can be stacked towards earning the Graduate Certificate. For those seeking to advance further, the credits from the graduate certificate can be applied towards a Master’s degree, providing a clear pathway for continuous professional growth.

“This flexibility allows them to personalise their learning journeys while juggling multiple commitments,” said Assistant Professor Mark Teo, who leads sustainability-related Continuing Education and Training (CET) courses at SIT.

“We want to let learners know that if they want to upskill, there is a pathway for them to upgrade their qualifications while managing their other commitments,” he added.

The decision to offer the modules on a full-day schedule is also a deliberate one.

“Though learners will need to take time off work, our preference is for them to attend the course during the day, because by the time it is evening, you are in the winddown mode and it is harder to pay attention,” noted Asst Prof Teo.

“We are cognisant of the challenges faced by learners who are studying part-time and working

full-time,” he added.

The Graduate Certificate in Sustainability Principles and Practices is open to the public, including those who may not be pursuing the IES Engineering Chartership in Sustainability. Organisations can also partner with SIT to offer this course as customised training for their employees, integrating industryspecific case studies to meet unique corporate needs.

Growing the sustainability talent pool

The programme emphasises group project-based assessments to mirror real-world industry practices, where collaboration across diverse fields is needed to create holistic solutions.

“Sustainability has a horizontal layer of knowledge. As an engineer, you need to make sure that the engineering works, but you also need to know the business side and the science of things. This is why our programme integrates these perspectives,” explained Asst Prof Teo.

More sustainability-focused programmes are in the works. Future offerings will cover leadership, strategy, innovation and business, underscoring SIT’s comprehensive approach to sustainability education.

Beyond compliance with regulations, the integration of sustainability and business practices will help drive innovation and enhance economic resilience. Engineers are pivotal to this transition, as they oversee the processes and solutions necessary for sustainable development.

“If we can get the engineers on board, the impact will be exponential,” said Asst Prof Teo.
