ENERGY RESILIENCE AND INDEPENDENCE OVERTAKE CLIMATE CONFIDENCE, STUDY REVEALS

Anew major study from Siemens reveals geopolitics is reshaping infrastructure strategy, with national energy security overtaking global climate cooperation as the primary driver of the energy transition. The Siemens Infrastructure Transition Monitor 2025 reveals senior leaders believe a resilient energy supply should be the top governmental priority among infrastructure transition goals – up from third place in 2023. Meanwhile, national energy independence and the proactive management of climate risks have seen the most significant growth in priority.

Rising global instability is intensifying market and supply chain volatility. To mitigate the use of energy as a geopolitical tool, governments are prioritizing security, independence, and preparedness alongside climate mitigation.

The report, based on a global survey of 1,400 senior executives and government representatives in 19 countries, highlights a shift: from a multilateral vision of clean energy to one increasingly centered on sovereign resilience and regional production. With mounting pressure on public and private energy systems amid overlapping climate, geopolitical, and market challenges, it finds that energy resilience is now seen as a critical enabler of the clean energy

transition – not a trade-off against it.

Over three in five (62%) respondents believe future energy systems will rely more on local or regional production than global trade, with key enablers including renewable integration, storage readiness, and advanced grid systems. Already, over half say resilience (53%) and energy independence (52%) are reaching maturity or are advanced within their countries –signaling a shift in infrastructure priorities is already underway.

With resilience and energy security now taking precedence, confidence in achieving global climate goals is starting to fall. More than half (57%) of global executives expect increased investment in fossil fuels over the next two years, and just 37% of businesses now believe they will meet their 2030 decarbonization targets – down from 44% in 2023.

With confidence in climate goals declining and 2026 strategies in development, the report highlights that failure to embed resilience into energy planning risks both economic and environmental fallout. At a time when governments are recalibrating net zero strategies alongside welfare and growth agendas, Siemens underscores that through

grid investment and digital innovation, progress towards climate commitments as well as energy resilience can be accelerated. As national energy strategies evolve, digital technologies remain at the heart of the infrastructure transition. Digitalization ranks as the second most important factor in accelerating the clean energy transition for industries – just behind expanding energy storage – with AI expected to have the greatest positive impact. Respondents believe that AI is helping to make critical infrastructure more resilient (66%) and report that their organizations are using AI to help decarbonize their operations (59%). www.siemens.com/global/en/ company/about/businesses/ smart-infrastructure.html

UK BUSINESS ENERGY USAGE ON THE RISE

POWWR has released its eighth Quarterly Energy Barometer Report, revealing that average energy usage has increased from just over 21 MwH of energy a year to just under 22 MwH. Businesses in London had the biggest rise in energy usage during the quarter (up 9.1% from 21286 KwH to 23224 KwH), making them the second biggest consumers of energy now in the UK, and second only to those in South Scotland (24234 KwH). In fact, businesses in London now consume almost a quarter more energy than those in the West Midlands (19708 KwH).

“While energy usage has increased for the first time this year, it is still 8.3% less than during the same period last year,” explains Matt Tormollen, CEO, POWWR. “Most of the increase was from businesses that use between 30-100 MwH a year. Smaller businesses, by contrast, saw little change and very large businesses that use over 100 MwH per annum actually saw their energy usage drop by over 3.3%.”

On average, UK businesses are paying 3.2% more for their electricity this quarter than last. “Some of this increase could be down to suppliers already including the TNUoS

charge and nuclear RAB levy prior to them coming into play in November. The cost of energy, on average, is still 13.3% less than this time last year however,” says Tormollen.

Despite these changes, businesses in the UK continue to commit to energy contracts of just under two and a half years (28 months), with little variation between regions. For those businesses looking to reduce their spend by switching suppliers, there are good deals available for those willing to shop around. In fact, businesses could save over 2% on average by switching suppliers.

The POWWR Quarterly Energy Barometer Report provides valuable insight into just how much energy UK businesses are consuming and what they are paying for it. The report is based upon over 600,000 separate data points covering a variety of businesses, from boutique start-ups to large industrial and commercial organisations.

“Whilst energy usage and bills have both risen slightly this quarter, the future for the UK energy market continues to look bright. Usage and bills are significantly less than they were last year, the willingness by some businesses to sign long contracts shows positive market

sentiment, and there are deals to be had for those willing to shop around,” adds Tormollen.

KEY FINDINGS

Average energy usage is 3.6% more than last quarter

Businesses in London had the biggest rise in energy usage (up 9.1%)

• The biggest consumers of energy are businesses in South Scotland (24234 KwH)

DOES ENERGY EFFICIENCY HOLD THE KEY TO MEETING EU ENERGY & CLIMATE GOALS?

In recent months, the European Commission (EC) has put energy efficiency front and centre in what it describes as a “new impetus” for reaching EU energy and climate goals.

The focus of the EC’s dedicated campaign was unpacked at the IEA Global Energy Efficiency Conference in Brussels on the13 June 2025 where the Commissioner for Energy and Housing, Dan Jørgensen, pledged a renewed commitment towards energy efficiency.

The central premise was articulated as such: “to fight climate change, to provide our people with affordable clean energy, for our own security, energy efficiency needs to be at the core of everything we do”.

Among the list of ten energy efficiency areas and a number of specific deliverables – including an Efficiency Action Forum with EU countries and a guarantee scheme for SMEs – was the need, quite simply to increase energy efficiency awareness among businesses and communities.

How key could energy efficiency awareness be in supporting a Europe-wide clean energy transition and helping to protect businesses from the impacts of price and supply volatility? Let’s explore.

THE CASE FOR ENERGY EFFICIENCY

I should firstly note that the conference also saw the launch of a new paper from the International Energy Agency (IAE), “Gaining an edge – the role of energy efficiency in industrial competitiveness”. The report’s findings provide a good basis for exploring common obstacles to energy efficiency and where organisations are seeing value.

The paper notes that while industrial energy demand has seen significant growth in recent years, driven by China and India, progress in industrial energy efficiency has slowed and stagnated.

SEFE Energy

can be significant – the IAE calculates that for EU firms with high energy costs and thin profit margins, that a 10% energy saving is equivalent to the profit from a 4-16% increase in sales.

The report also noted a connection between energy efficiency investments and labour productivity or job satisfaction. A link between these investments and improved indoor environments – better lighting, air quality and thermal comfort are often tied to enhanced worker satisfaction and attendance.

KEY OBSTACLES TO ENERGY EFFICIENCY

From the IAE’s surveying of 1,000 industrial firms across 14 countries it found that, unsurprisingly, upfront cost barriers were identified by companies as the main obstacle to implementing energy efficiency improvements. This was followed by information barriers (lack of data to make the business case or understanding on available options) and skills shortages in key energy efficiency occupations.

The data point is key one – to put it plainly, accurate data is absolutely essential. In order to measure energy efficiency improvements, we need precise data to track energy consumption accurately. By analysing historical data, we can identify inefficiencies, pinpoint areas for improvement, and predict future energy needs – a key part of becoming more energy efficient.

Linked to this is the value of audits for helping us understand trends and patterns in energy use. Less than a third of the surveyed companies had carried out an energy audit in the past five years and for companies with fewer than 100 employees, only 15% had carried out an energy audit in the last five years.

THE VALUE OF QUICK-WINS

While the report goes on to articulate the bigger scale policy asks to best support industry in reducing energy usage, it also hones in on the “quick-win” measures that can help to deliver savings – everything from power management of equipment and installation of LED lighting systems and encouraging behavioural changes.

It may sound simple, but educating teams about smarter energy management is one of the most effective ways to set in place the core foundations needed to help reach net zero.

At SEFE Energy, we’ve seen firsthand the benefits of this culture change and education piece for staff. An employee-led energy strategy is always going to reap stronger results – when this is aligned with a wider sustainability programme and goal, it’s more likely to galvanise employees.

As underscored by the European Commission and the findings of the IAE, energy efficiency offers farreaching benefits, from reducing costs to improving working conditions and driving industrial competitiveness. Even modest efficiency gains can yield significant financial returns and greater resilience against market volatility.

While the EC’s full vision will only be realised with the support and collaboration of Governments and policymakers, energy efficiency is one of the most effective tools we have now to work towards net zero goals and this can begin quite simply with awareness, auditing and action. www.sefe-energy.co.uk

LOCAL VOICES, LOCAL PLANS: HOW ENERGY PLANNING CAN UNLOCK NETWORK INVESTMENT

Across the UK, the drive to decarbonise and establish a more secure energy system is colliding with one of the most persistent challenges in the energy system –network constraints. As demand grows from new homes, electric vehicles, heat pumps and data centres our local electricity networks are struggling to keep up. Projects stall, connection queues lengthen, and investment is delayed.

It’s a familiar story for many energy managers: there’s the will, the technology, and often the funding – but not always the capacity. What’s missing is a clear, a locally grounded view of what is needed, where it’s needed, and when it will happen to influence regulatory investment. That’s where Local Area Energy Planning (LAEP) is beginning to make a real difference.

Network constraints: a blocker to local energy investment

The scale of the challenge is stark. Many Distribution Network Operators (DNOs) report record connection requests – from solar farms, industrial sites, housing developers and energy-hungry data centres. Yet without visibility of local authority development plans or community ambitions, network investment has often been reactive, not proactive. This disconnect slows the energy transition and threatens local growth. If the grid can’t expand in step with predictable local need, opportunities for jobs, housing, investment and innovation risk being lost or significantly delayed.

How LAEPs change the picture

Energy Systems Catapult has been at the forefront of developing and delivering Local Area Energy Plans – detailed, spatial, data and stakeholder-driven blueprints that help local areas understand their pathways to net zero and the potential impact on the energy networks. Crucially, as well as providing insight for delivery stakeholders and to target investment, LAEPs bridge the information gap between local plans and network planning. Informed by scenario analysis to identify low-regret projects across a local area, LAEPs help stakeholders target and buy-into delivery plans, meaning network operators can have greater confidence in what’s coming – where EV uptake will surge, where solar deployment is viable, where electrified heating will add load. They can then compare this bottom-up insight to their Distribution Future Energy Scenarios (DFES) and long-term investment plans, allowing

Andy Clark, Business Leader –Place, Energy Systems Catapult

networks to target upgrades ahead of need.

In short, LAEPs improve forecasting, sharpen investment decisions and reduce risk.

We’re already seeing this play out across the UK. Dozens of councils have completed or commissioned LAEPs, and many more are using them to support local planning, funding bids, and engagement with their DNOs. Where they exist, investment conversations become more productive. Network planners can test assumptions with solid local data; local authorities can evidence why upgrades are needed.

From local plans to regional strategy

This local insight can now also add value through the new Regional Energy Strategic Plan (RESPs) process, led by the National Energy System Operator (NESO). RESP brings together data from local authorities, network operators and regional stakeholders to produce a shared picture of energy needs across each region.

Through the Ready for RESP 2025 programme, Energy Systems Catapult is helping local authorities feed their LAEP data into this regional process. The aim is a consistent, transparent basis for future network investment – one that aligns with local priorities, supports housing and industrial growth, and maximises use of local opportunities such as for renewable energy deployment.

If LAEPs and RESPs work hand-inhand, we get a virtuous circle: local plans inform regional forecasts, which shape network investment. That’s how we move from a reactive to a strategic system.

Unlocking growth across housing, solar and data centres

The impact of better alignment between energy planning and infrastructure investment is far-reaching.

• Housing: Developers need confidence that network capacity will be available where new homes are planned. With LAEPs identifying future demand hotspots, DNOs can invest earlier, enabling housing growth to proceed on schedule and supporting integrated low-carbon heating and EV charging infrastructure.

• Solar and renewables: Local spatial mapping helps identify where solar

generation can be deployed efficiently – avoiding constrained areas and making best use of existing headroom. This reduces curtailment, unlocks viable projects and makes planning more predictable.

• Data centres and high-demand users: These are essential for the digital economy but require guaranteed power and grid resilience. LAEPs and RESP data can show where capacity exists or where investment will unlock strategic locations – making regions more attractive for high-tech investment.

• Regional priorities: Ultimately, energy planning done well supports the wider growth agenda – targeting investment in regions that need it most, stimulating local jobs and supply chains, and building more resilient, inclusive economies.

Delivering ahead of need

To make this work at scale, a few shifts are essential. Local authorities need resourcing and skills to produce high-quality LAEPs. Data sharing between councils, network operators, regional planners and the RESP must be effective and standardised. And regulators must give networks the confidence to invest ahead of demand when robust local evidence shows it will be needed. Because the cost of waiting – stalled connections, lost growth, and missed decarbonisation targets – is far greater.

A local-first energy transition

The UK’s energy transition will be won or lost at local level. The combination of Local Area Energy Plans and Regional Energy Strategic Plans offers a once-ina-generation opportunity to rewire how we plan and invest in infrastructure. By aligning network investment with real local needs, we can unlock faster deployment of clean technologies, accelerate housing delivery, and attract new industries. Local voices, local data, and local plans are not just inputs to the energy transition – they are the key to making it deliverable. Want to find out more?

SURVEYS: THE KEY TO UNLOCKING UP TO 40% ENERGY SAVINGS

Imagine walking into your building and instantly knowing where energy is being wasted, which systems are under strain, and what simple behavioural or operational tweaks could deliver real, measurable savings. That’s the power of a Building Energy Management System (BEMS), and even more so, the power of understanding how to use it effectively.

Globally, buildings account for around 40% of total energy use and 36% of CO2 emissions. Yet studies show many buildings run at just 60–70% of their designed efficiency. This gap represents a huge opportunity for improvement and cost savings.

An underperforming BEMS is often the result of:

• Incorrect specification or control strategy

• Poor installation or commissioning

• Faulty or badly positioned sensors

• Inadequate training or maintenance

JRP Solutions, energy and sustainability specialists, help organisations get their BEMS working as a true business asset. Their proven six-step process starts with a detailed audit and ends with measurable impact: lower bills, reduced maintenance and a lighter carbon footprint.

STEP 1: UNDERSTANDING THE BUILDING

No two buildings operate the same way. JRP begins with a comprehensive walkthrough and stakeholder interviews to understand how the building actually functions day-to-day. This diagnostic phase focuses on: Occupancy patterns and space utilisation

• Usage of HVAC, lighting, and auxiliary systems

• Manual overrides and comfort complaints

• Scheduled operation vs. actual use

• Energy consumption and peak demand analysis

This process reveals how the building performs in practice, identifying the common gap between design intent and operational reality – one of the largest sources of wasted energy in commercial facilities.

STEP 2: GETTING TO KNOW YOUR BEMS

A BEMS is the brain of your building, managing heating, cooling, lighting, and ventilation. But like any brain, it needs tuning. According to CIBSE (2021), a poorly configured BEMS can waste 20–40% more energy than one that’s optimised. JRP’s in-depth analysis includes:

• Checking sensor accuracy and calibration (drift can cause 15–25% efficiency loss)

• Reviewing control strategies and schedules

Evaluating data quality and integration

Assessing alarm and fault detection systems

Reviewing historical performance trends

This stage often uncovers quick wins, such as systems running outside occupancy hours or heating and cooling competing with each other, which can waste up to 30% of HVAC energy.

STEP 3: BEHAVIOUR MAKES THE DIFFERENCE

Technology alone isn’t enough. Building users and operators play a vital role in energy performance. Studies by EnCO and IFMA show that up to 50% of savings can come

from behavioural changes, with engaged occupants outperforming similar buildings by 15–25%.

JRP helps teams: Understand energy impact through real-time dashboards

• Build sustainable habits aligned with business goals

• Protect investments through correct BEMS use

• Run energy awareness campaigns and competitions

Providing regular feedback on energy use can cut consumption by 5–15% within the first month. It’s about empowering smarter choices, not assigning blame.

STEP 3.5: INTEGRATING INSIGHTS INTO A WIDER SUSTAINABILITY STRATEGY

Beyond operational savings, insights from BEMS surveys strengthen corporate sustainability goals. JRP’s data-driven approach supports: ESG reporting and verified energy metrics

• Green building certifications (e.g. BREEAM)

• Science-Based Target (SBTi) alignment

• Compliance with UK Energy Savings Opportunity Scheme (ESOS)

• Broader carbon reduction and climate commitments Buildings that integrate BEMS

data into sustainability frameworks achieve stronger ESG scores and enhanced investor confidence.

STEP 4: INSIGHT INTO ACTION

After analysis, JRP delivers a clear, prioritised action plan following ISO 50001 principles and CIBSE best practice. Reports include:

• Benchmarking against industry standards

• Practical recommendations with payback analysis

Lifecycle cost assessments

Risk and change management strategies

Each recommendation is costed, sequenced, and designed for measurable impact.

STEP 5: SUSTAINING THE CHANGE

Energy savings can erode by 10–25% each year without consistent monitoring. JRP ensures improvements last by helping teams:

• Train facilities staff

• Establish monitoring and reporting routines

• Implement continuous commissioning

Maintain effective feedback loops Buildings with ongoing monitoring typically retain 95% of their initial savings over five years.

THE BUSINESS CASE

Whether you’re a facilities manager, sustainability lead, or business owner, a high-performing BEMS delivers benefits far beyond energy savings.

FINANCIAL IMPACT

• Lower operating costs

• Increased asset value

• Improved productivity

RISK MANAGEMENT

• Reduced exposure to rising energy prices

• Stronger regulatory compliance

• Lower risk of equipment failure

STRATEGIC ADVANTAGES

• Enhanced corporate reputation

• Support for ESG and Net Zero goals

• Greater attraction and retention of talent

IMPLEMENTATION TIMELINE AND INVESTMENT

A typical BEMS survey and optimisation project follows this structure:

Weeks 1–2: Initial assessment

Weeks 3–4: Analysis and recommendations

• Weeks 5–6: Report delivery

• Months 2–6: Implementation and fine-tuning

• Ongoing: Monitoring and continuous improvement Investment usually ranges from £5,000–£25,000, with most clients achieving payback within 12–24 months.

READY TO START?

For 25+ years, JRP Solutions has helped clients unlock the full potential of their BEMS, improving efficiency, empowering staff, and accelerating progress toward Net Zero.

A BEMS survey provides the roadmap, but success comes from combining smart technology with informed, engaged people.

From rising energy costs and ageing infrastructure to the critical need for clean air and uninterrupted operations, the pressure to deliver safe, efficient, and sustainable care has never been greater. E.ON Optimum is a cutting-edge energy management platform designed to meet these complex demands.

THE HEALTHCARE ENERGY CHALLENGE

Hospitals are among the most energyintensive buildings in the public sector. With 24/7 operations, strict climate control requirements, and a wide array of medical equipment, inefficiencies can quickly escalate into operational risks and financial strain. Traditional building management systems (BMS) often fall short with fragmented data, limited visibility, and reactive maintenance leaves facilities teams struggling to keep up. Optimum changes the game. By integrating seamlessly with existing infrastructure, including legacy BMS and smart meters, Optimum provides intuitive dashboards for monitoring, managing, and optimising energy use and air quality across the entire hospital estate.

• Cost Savings: Facilities managers can confidently track anomalies, benchmark performance, and plan interventions. Optimum’s automated alerts flag excess energy use, such as HVAC systems running overnight due to faulty sensors. In one use case, a single faulty sensor was costing our customer over £26,000 annually in wasted energy. With Optimum, the issue was detected and fixed remotely, saving 120,000 kWh and delivering instant ROI.

• Improving Patient Comfort and Air Quality: Indoor air quality isn’t just a comfort issue; it’s a matter of patient safety. Poor ventilation can increase the risk of infection transmission, especially in high-traffic areas like waiting rooms and wards. Optimum enables hospitals to monitor CO2 levels, humidity, and air

circulation in real time, helping facilities teams maintain healthy environments and comply with infection control standards.

• Remote Diagnostics and Maintenance Efficiency: Hospitals often operate with lean maintenance teams stretched across large estates. Optimum’s remote access capabilities empower engineers to diagnose and resolve issues without unnecessary site visits. Whether it’s a boiler fault in a surgical wing or a lighting anomaly in a car park, teams can respond faster, reduce downtime, and prioritize high-impact interventions.

THE ENERGY SOLUTION FOR MODERN HEALTHCARE

Healthcare organisations often face tightening budgets, greater accountability, and the urgent push toward net-zero. Optimum addresses each of these challenges head-on:

• Budget Relief: Optimum isn’t just a tool; it’s a strategic asset. Organisations using the platform have reported annual savings that far exceed the cost of implementation, with some achieving six-figure reductions in energy spend. These savings can be reinvested into frontline services, equipment upgrades, or sustainability initiatives.

• Customisable dashboards: Hospitals can customise dashboards, tag meters by department, and track performance across multiple sites. Customisable dashboards let teams compare air quality across departments, spot underperforming zones, and act before issues escalate improving patient outcomes and staff wellbeing. Whether managing a single acute care facility or a regional trust, Optimum adapts to your needs.

• Net Zero Alignment: The platform supports carbon reporting and sustainability tracking, helping hospitals meet government targets. Features like load analysis, benchmarking,

and project tracking enable decisionmakers to plan and validate energy efficiency projects with precision.

• Future-Proofing: Optimum’s open protocol architecture ensures compatibility with a wide range of technologies from legacy systems to emerging IoT devices, meaning today’s investment won’t become tomorrow’s limitation.

THE ROLE OF MEASUREMENT AND VERIFICATION IN MEETING CARBON EMISSION TARGETS

Decarbonisation has emerged as a dominant trend across public, private, and domestic sectors since the UK government’s 2019 commitment to achieving net zero emissions by 2050. Initiatives such as the Public Sector Decarbonisation Scheme (PSDS) have been instrumental in advancing this agenda, particularly within the public domain, and have formed a core part of my role at Salix.

A significant focus has been placed on enhancing building efficiency by reducing heat demand through a fabric-first approach. This involves upgrading elements such as double or triple glazing and cavity wall insulation. When combined with the installation of low-carbon heating technologies such as heat pumps, organisations can significantly reduce their reliance on fossil fuels, particularly natural gas.

The impact of the Public Sector Decarbonisation Scheme has been substantial, with more than 1.2 million tonnes of carbon dioxide saved annually. However, this raises a critical question: how can we be certain that the reported savings are accurate? As earlier phases of the Public Sector Decarbonisation Scheme have concluded, they’ve laid the groundwork for annual carbon reporting.

Once organisations have operated their new heating systems for at least a year, they are required to report on their energy usage. Yet, it has become clear that monitoring and verification (M&V) are often overlooked once the initial decarbonisation goals are met.

So, what exactly is M&V and why is it essential? This question is increasingly relevant for grant recipients entering the post-completion phase. Monitoring refers to the collection and recording of performance data, while verification ensures the accuracy and reliability of that data. Within the context of the Public Sector Decarbonisation Scheme, M&V pertains specifically to carbon savings.

Low-carbon heating systems, like any technology, may not always perform as expected. This makes ongoing monitoring crucial for providing

Nicola Gresty, Energy and Carbon Programme Manager, Salix

a detailed, year-on-year assessment of actual carbon reductions. In the Public Sector Decarbonisation Scheme, M&V plays a pivotal role in evaluating the effectiveness of governmentfunded low-carbon solutions across a wide spectrum of public sector organisations, from NHS trusts and police stations to primary schools.

One key tool in this process is Heating Degree Day (HDD) data, which helps quantify savings by accounting for variations in weather. For instance, if the baseline year was unusually warm, heating demand would have been lower, potentially skewing results. Heating Degree Day data normalises these anomalies, offering a more accurate and proportional comparison across different time periods and geographic areas. This methodology is embedded in the Public Sector Decarbonisation Scheme annual carbon reporting, enabling public sector bodies to assess performance and strategically plan future sustainability initiatives.

While validating carbon savings is essential, effective Monitoring and Verification (M&V) goes further, creating a valuable feedback loop that informs future decision-making. When organisations can identify underperforming systems, they gain insight into where energy efficiency opportunities are being missed. This enables early interventions, enhancing both financial returns and environmental impact.

The integration of digital technologies, such as smart meters, supports this process by enabling real-time performance tracking. This reduces reliance on manual reporting and enhances transparency across operations.

However, the success of M&V depends not only on technological solutions but also on cultivating internal expertise. Many public sector organisations face resource limitations, highlighting the need to upskill staff in areas such as carbon accounting, data analysis, and system optimisation. This need is increasingly evident through our engagement with Public Sector Decarbonisation Scheme grant recipients.

The data collected through schemes like the Public Sector Decarbonisation Scheme has the potential to inform national policy, spotlight best practices, and shape future funding models. In this way, M&V contributes not only to accountability but also to collective learning across the public sector.

By continuing to gather and analyse this critical data, we have the opportunity to showcase the environmental and financial value of decarbonisation projects. It’s not just about measuring impact at the point of installation, it’s about understanding how those impacts are sustained and improved over time.

Looking ahead, I believe that any new or ongoing decarbonisation efforts must be underpinned by a robust M&V strategy. This will empower organisations to confidently link installed measures to actual carbon savings, paving the way for more predictable and impactful outcomes.

We remain optimistic about the future. As the UK advances toward its 2050 net zero target, the role of M&V will become increasingly vital. By embedding M&V into our organisational culture, we move closer to a future where carbon savings are not only projected but also proven. www.salixfinance.co.uk

INTELLIGENT BUILDING CONTROL – HARNESSING DATA AND AUTOMATION TO ACHIEVE NET ZERO

The decarbonisation of the built environment is central to global efforts to mitigate climate change. With operational emissions from buildings contributing approximately 28% of total global carbon dioxide emissions (according to the Global Alliance for Buildings and Construction), innovative technologies are required to address both energy efficiency and carbon reduction at scale. Sophisticated cloud-based energy management systems such as Irus, are emerging as a key enablers in the drive to net zero within the multi-occupancy buildings sector (PBSA, BTR, Co-Living, Hotels etc.).

For these operators where electricbased heating and hot water loads are significant, the decarbonisation of the grid will provide benefits from lower Scope 2 emissions. However, intelligent building control systems will identify internally where targets are not being met and improvements can be made – for example, energy waste through heating empty rooms, or when windows are open.

A TECHNICAL OVERVIEW

Functioning as a centralised IoTdriven control platform that integrates multiple data streams from across a building’s infrastructure, these systems primarily focus on space and water heating, traditionally the most energyintensive aspect of building operations.

Key technical components include:

• Individual room environmental sensors and control: Temperature, occupancy, humidity, light, sound pressure and CO2 sensors integrated within the ControlSensor feed realtime environmental and behavioural data into a central control Portal.

• Data. Insight. Action: Historical and real-time data is analysed to optimise setpoints, modulate heating loads, and minimise unnecessary energy expenditure.

• Cloud-based Analytics Engine: Bespoke software tools process vast amounts of data, providing continuous optimisation.

• API Integration: Could enable seamless interoperability with existing Building Management Systems (BMS) and other platforms, renewable energy assets, and external data sources (including weather forecasts).

DECARBONISATION MECHANISMS

1. Demand-Responsive Heating Control. Traditional time-based heating schedules often fail to reflect actual occupancy and usage patterns, particularly in student accommodation, leading to substantial energy wastage. This tech uses real-time occupancy detection to enable demand-led heating control, ensuring that rooms only use energy when required. This granular control reduces both energy consumption and peak load demand.

2. Adaptive Setpoint Optimisation. Temperature setpoints are adjusted within defined comfort bands based on variables such as external temperatures, occupancy, and interaction with the system by the room occupant.

3. Predictive Maintenance and Fault Detection. By monitoring equipment performance trends, anomalies can be identified – indicative of equipment inefficiency or impending failure, enabling proactive maintenance. This optimises asset life cycles and avoids the carbon costs associated with inefficient equipment operation.

QUANTIFYING THE IMPACT

Irus installation analysis has shown operational energy savings in the range of 30–35%, with heating load in some cases

reduced by as much as 50%, depending on building type and baseline system efficiency. These savings directly translate to substantial CO2e reductions, contributing materially toward corporate ESG reporting, regulatory compliance, and sustainability certifications such as BREEAM and GRESB. For large building portfolios, centralised control and data aggregation, facilitates portfolio-wide energy optimisation strategies, consistent reporting frameworks, and the ability to benchmark asset performance across multiple sites.

ENABLING THE TRANSITION TO NET ZERO

Intelligent building control exemplifies the convergence of IoT, cloud computing, and AI-powered control in delivering practical decarbonisation pathways for the built environment. By enabling precise, responsive, and predictive control of building systems, it empowers facilities managers, energy consultants, and sustainability professionals to materially reduce operational carbon footprints while maintaining occupant comfort and operational resilience. As regulatory pressures tighten and the financial implications of carbonintensive operations grow, the integration of intelligent control systems will become an increasingly indispensable component of net zero building strategies.

CAN THE GRID KEEP UP? AS GLOBAL TEMPERATURES RISE SO DOES THE NEED FOR COOLING

Can our electricity grids handle the heat – and can governments accommodate growing demand without infringing upon NetZero ambitions? Rinnai Managing

Director Tony Gittings looks at the accelerated increases in demand for cooling technology due to global warming.

Arequirement for properties to be cooled during summer months is becoming ever more sought after by both international and UK customers. Global temperatures have proven to be rising, largely due to human activity. Records have confirmed that 2024 was officially the warmest year on record and the first calendar year that the average global temperature exceeded 1.5°C above pre-industrial level.

In recent times the UK has also recorded the highest ever temperature, 40.3C on 19th July 2022 in Lincolnshire. Official Met Office data has confirmed that 2025 was the hottest summer since records began in 1884. From the 1st of June (2025) to 31st August, the average temperature was 16.10°C, 1.51°C above the long-term meteorological mean temperature. The previous record was set in 2018 and was recorded at 15.76°C.

Incidentally, all five of the hottest average temperatures recorded in the UK were in between 2002 and 2025. These officially recorded figures can be viewed as being indicative of a trend that demonstrates the local UK climate of increasing heat.

This official data highlights why air conditioning and cooling is fast becoming a burgeoning problem for the property stock during the UK summer period. It is estimated that 3% of UK homes currently have air conditioning, whilst some researchers have projected that

as many as 79% of UK domiciles will contain cooling devices by 2085.

In well populated predominant countries such as China and the USA air conditioning is far more prevalent. Over in the USA around 90% of homes have air conditioning according to a 2020 federal-government survey. The number of homes in China that utilise air conditioning is around 60%. In Hong Kong 99% of dwellings possess AC units.

In the European block – where demand for building cooling has been historically lower when compared to the more humid and hotter climates of America and China, around 20% of private dwellings own air conditioning facilities. Of this percentage France accounts for 25% and in Germany only around 3% of homes are in ownership of cooling technology.

HVAC systems in all the aforementioned countries will experience an increase in demand not only in private accommodation but also in public and commercial premises. A major future issue is now expected regarding the expansion of cooling AC systems: how will the increase of electricity production, distribution and usage affect Net Zero ambitions across the globe? And how

will international governments ensure the farming of reliable and responsible sources of power that will fuel additional pressure on separate national grids.

The UK government is in the process of drafting a “Cooling Outlook” document – which aims to present a series of measures that identify policy, data and practises which guarantee air conditioning is aligned with global cooling pledge commitments.

The Global Cooling Pledge (GCP) was established during COP28 by the United Arab Emirates. The GCP consists of a coalition of voluntary countries, cities and non-state organisations that are committed to reducing coolingrelated emissions by 68% before 2050.

Further aims held by GCP members include increasing access to sustainable and responsible cooling by 2030 as well as improving the efficiency of new air conditioning units by 50%, also by 2030. The GCP further aims to absorb cooling into national and global climate goals and set forward ratified building standards that utilise strict and sustainable material procurement practises.

A key element of the GCP will be widespread international cooperation that will share gaps in policy, data

and technological improvements. Countries that have signed up for the Global Cooling Pledge include: the US, Canada, UK, Germany, France, Spain and the Netherlands.

In relation to domestic UK framework, the precise purpose of the “Cooling Outlook” document will be to offer a single authorised paper of all aspects concerned with UK cooling; issues that will be explored and improved upon consist of policy refinement, cooling related data accumulation and sharing, government interdepartmental collaboration in creating a shared understanding of domestic cooling approach and promoting the adoption of sustainable cooling technology.

A majority of air conditioning units are powered by electricity and renewable sources of fuel such as wind or solar. European gross electricity consumption in the year 2023 shows that 45.3% was derived from renewable sources. UK figures from between January 20242025 demonstrate that 42.3% of all generated electricity was cultivated via clean renewable resources.

Clean Chinese electrical generation is advancing far beyond any other nation with rapid construction of multiple renewable installations. It was reported in June 2025, that China had installed 93GW of solar capacity in May 2025 “100 solar panels every second.” Between January and May 2025, China had included 198GW of solar and 46GW of wind capacity into domestic operations, producing as much electricity as Turkey or Indonesia.

American electricity is dominated by natural gas where 43.1% of electrical output is produced via fossil fuels. But the second highest contributor to national electricity supplies is met by renewables who account for 21.4%.

As more utility scale renewable projects are added to European, UK, Chinese and American power grids,

larger volumes of clean electricity can be accessed by air cooling technologies, meaning that AC units can be considered a clean utility.

Due to rising global and domestic UK temperatures the use of cooling technologies is projected to rise across all countries. As to limit any additional emissions that could be added to international and national carbon loads, preparations and measures that specifically focus on air conditioning must be implemented towards official environmental targets.

The Global Cooling Pledge (GCP) and the UK “Cooling Outlook” document are evidence that an increase in cooling

systems used by buildings in summer are under serious observation.

TRANSFORMING HIGHER EDUCATION: ANGLIA RUSKIN UNIVERSITY’S JOURNEY TO NET ZERO

In collaboration with Anglia Ruskin University (ARU), TEAM Energy’s latest Customer Spotlight features Simon Chubb, Head of Sustainability, sharing powerful insights on embedding net zero into university life.

This in-depth conversation explores how ARU is embedding sustainability into every facet of university life, from operations and teaching to community engagement, and offers practical insights for organisations pursuing their own net zero ambitions.

LEADING BY EXAMPLE IN HIGHER EDUCATION

ARU is at the forefront of the UK’s net zero movement, driven by a mission to transform lives through innovation and responsibility.

As Simon Chubb explains, “Achieving net zero is deeply aligned with Anglia Ruskin University’s mission to transform lives through innovative and entrepreneurial education and research. Our core values, including innovation, responsibility, and community, are reflected in our commitment to sustainability. We see it as our responsibility not only to our students, but also to the communities we serve and future generations.”

STRATEGIES AND PROGRESS

• Zero Carbon Operations: ARU has achieved zero carbon in Scope 2 emissions through a pioneering power purchase agreement, sourcing 20% of its base load power from wind farms and the remainder from nuclear energy, ensuring a fully zero-carbon electricity supply.

• Decarbonising Infrastructure:

The university is investing in district heating and advanced building management systems, aiming for zero carbon in Scope 1 emissions by 2035. These upgrades are part of a 10-year investment programme to transform over 75 buildings across its campuses.

• Tackling Scope 3 Emissions: ARU is targeting net zero for Scope 3 emissions by 2045, with initiatives like a university-wide travel management system that tracks and reduces carbon from business and academic travel.

ENGAGING THE UNIVERSITY COMMUNITY

ARU’s award-winning ARU Green programme is a standout example of effective engagement. The initiative encourages students, staff, and stakeholders to take weekly sustainable actions, such as reducing energy use and choosing low-carbon travel. Since its launch, ARU Green has recorded 40,000–50,000 actions annually, saving around 100 tonnes of carbon each year.

OVERCOMING CHALLENGES WITH COLLABORATION AND INNOVATION

Despite financial and policy hurdles, such as the withdrawal of

government grant funding and rising energy costs, ARU has remained agile. The university has focused on practical, scalable investments and leveraged partnerships, including joint power purchase agreements and public sector frameworks, to share risk and access support.

ADVICE FOR OTHERS

For organisations beginning their net zero journey, Simon Chubb offers this advice: “Collaboration is key. No institution can do this alone. Sharing knowledge, resources, and support has been essential. Accept that the journey won’t be perfectly mapped out. What matters is knowing your direction of travel and committing to it. Be flexible, stay focused, and build momentum through achievable steps. That’s how we’ve made progress, and how others can too.”

WHY FM MUST LEAD THE ENERGY TRANSITION

The race to net zero is reshaping every aspect of the built environment. From heat decarbonisation to intelligent energy management, organisations are under pressure to cut carbon without compromising operational resilience. Yet amid the complexity of legislation, funding, and technology, one truth stands out: facilities management (FM) teams are uniquely positioned to lead this transition.

FM: THE HIDDEN ENGINE OF DECARBONISATION

Facilities managers already sit at the crossroads of compliance, operations, and cost control. They understand how estates function day-to-day, and they hold the levers that influence energy performance: from plant maintenance to asset lifecycle planning. This makes FM not just a delivery partner, but a strategic enabler of decarbonisation. However, the role of FM in energy transition is often underestimated. Too many organisations still view sustainability as a separate workstream, disconnected from core facilities operations. That mindset needs to change. If net zero is to be achievable, FM needs to move from reactive maintenance to proactive energy management: embedding carbon reduction into every decision about how buildings are run.

THE CHALLENGES: COST, CAPABILITY, AND COMPLIANCE

For many estates, the barriers to decarbonisation can fall under three categories:

• Cost: Low-carbon technologies demand significant upfront investment. Heat pumps, smart controls, and on-site generation are expensive, and traditional budgeting models rarely account for lifecycle savings.

• Capability: Many organisations lack the in-house expertise to design and deliver complex energy projects. Understanding energy grid constraints, asset optimisation, and funding routes requires specialist knowledge.

• Compliance: Legislation is evolving fast. From Streamlined Energy and Carbon Reporting (SECR) to

Graeme Hamilton, Business Director – Energy, OCS

climate change agreements, the regulatory landscape is complex and the penalties for noncompliance are a major risk.

FM teams can address all three. They already manage complex frameworks, they can integrate energy strategy into operational planning, and they can unlock funding streams that make projects viable. At OCS, we’ve helped public sector customers secure grants under public sector decarbonisation schemes, while building investment cases based on lifecycle costing rather than short-term spend.

AI IN ENERGY MANAGEMENT: PROMISE VS REALITY

Technology is another critical piece of the puzzle. Artificial intelligence and machine learning are often touted as game-changers for energy management. Today, the technology is delivering real value in predictive maintenance and asset optimisation. For FM teams, this means moving away from reactive fixes to predictive maintenance. Algorithms can spot performance deviations early, allowing interventions before failures occur. This can result in reduced downtime while improving a building’s energy efficiency. However, there are caveats. Deployment remains patchy as AIenabled systems are expensive and require scale to be most effective. For most estates, the challenge is not access to technology, it’s integration. Tools and applications must be embedded into FM workflows, not bolted on as standalone solutions. In the years ahead, expect AI to become a mandated part of asset management. For now, FM leaders should focus on practical use cases that deliver measurable savings, rather than chasing the hype.

FUNDING WITHOUT FRICTION

One of the biggest misconceptions about decarbonisation initiatives is that they slow down operations. In reality, the

opposite is true, but only if the projects are planned and funded correctly. The key is to align energy upgrades with existing maintenance cycles and capital programmes. Replacing end-of-life assets with low-carbon alternatives, for example, avoids duplication of cost and disruption. Funding is available, particularly in the public sector, but accessing it requires expertise. Grant schemes prioritise projects based on carbon cost, and applications demand access to robust data. FM teams, supported by partners, can provide that evidence by mapping assets, modelling savings, and building the case for investment.

A STRATEGIC OPPORTUNITY

The energy transition is not just a technical challenge, it’s a strategic opportunity for organisations to rethink how its estates are managed. For FM providers, this means evolving from service delivery to energy leadership, combining compliance, technology, and operational insights into an integrated proposition.

Consider this: the UK public sector spends over £26 billion annually on digital technology and employs nearly 100,000 digital and data professionals, yet 47% of central government services still lack a digital pathway. These figures show that transformation is possible, and FM can be the catalyst for similar progress in energy management. At OCS, we’re focused on making decarbonisation achievable, affordable, and operationally sound. This means aligning strategy, funding, and delivery into a seamless process. The message for FM leaders is clear, don’t wait for someone else to lead. The tools, the remit, and the influence are already in your hands. Every building optimised, every system upgraded, every behaviour changed brings us closer to a sustainable future. www.ocs.com

BEYOND COMPLIANCE: HOW UNIVERSITIES ARE UNLOCKING DEMAND-SIDE FLEXIBILITY TO CUT COSTS AND CARBON

Across the UK, universities are redefining what it means to lead on sustainability. From heritage estates to research campuses, institutions are balancing ambitious net zero targets with rising energy costs and the need to keep spaces comfortable and operationally reliable.

While many are investing in renewables, heat pumps, and modern HVAC systems, the real opportunity lies in how energy is managed. Smarter demand-side innovation – including demand response and flexibility – is now helping higher education estates turn existing infrastructure into a strategic sustainability asset.

That’s where Voltalis comes in.

As a European leader in intelligent energy management, Voltalis helps buildings use less electricity when the grid is under pressure or wholesale prices spike, automatically, and without affecting comfort or performance. By connecting to electric heating, cooling, and hot water systems, Voltalis’ technology makes short, imperceptible adjustments that collectively deliver measurable reductions in consumption and carbon emissions. For universities, this means lower bills, verified Scope 2 savings, and enhanced resilience, all with no upfront investment or operational disruption.

At the University of Wales Trinity Saint David, the benefits are clear. In partnership with Voltalis, over 100 student accommodation rooms were equipped with demand response technology in under 15 minutes per installation, with no rewiring or disturbance to students. Within six months, the university saw a 13% reduction in electricity use across two accommodation blocks, over 5,000 successful grid-support events, and zero comfort complaints.

“Since installing the Voltalis solution, we’ve achieved a 13% reduction in electricity use across our student accommodation, all without any changes in comfort or behaviour,” says Daniel Priddy, Head of Sustainability at the university.

“That’s rare, especially in heritage buildings with complex infrastructure.”

This kind of operational flexibility is reshaping how universities approach both energy management and long-term resilience. Rather than relying solely on infrastructure upgrades or major capital projects, estates teams can now achieve immediate impact through smart, data-driven control. Demandside flexibility complements on-site renewables and storage, ensuring that electricity is consumed when it’s cleanest, cheapest, and least carbon-intensive.

As the UK grid becomes increasingly renewable and variable, flexibility isn’t just a sustainability measure, it’s a shield against volatility. By turning campus systems into active grid participants, universities are not only cutting emissions but actively supporting national energy stability.

The role of demand response in higher education will take centre stage at the UHEI Conference & Exhibition (Birmingham, 25–26 November), where Voltalis’ UK Managing Director Dr. Randall Bowen will moderate the panel “Beyond compliance: how smarter energy strategies are protecting budgets and

advancing net zero in higher education.”

Joining him on stage will be:

Daniel Priddy, Head of Sustainability, University of Wales Trinity Saint David Rachael Hanmer-Dwight, Head of Environmental Sustainability & Energy Services, University of Liverpool

• Stephen Creighton, Head of Member Services, The Energy Consortium (TEC)

Together, they’ll explore how intelligent energy management, operational innovation, and cross-sector collaboration can help universities move beyond compliance, turning estates into flexible, future-ready assets.

For the higher education sector, the message is clear: meeting sustainability goals doesn’t have to mean deep retrofits or difficult trade-offs. With smarter systems, better data, and proven demand-side technology, universities can achieve real progress – protecting budgets today while building the low-carbon campuses of tomorrow.

Because when campuses can think, flex, and adapt, they don’t just meet their targets – they lead the transition.

All together better.

REFURBISHMENT

INTEGRATED REFURBISHMENT DELIVERS ENERGY AND CARBON SAVINGS AT TOWERS SCHOOL

TURNING A MAINTENANCE PROBLEM INTO AN ENERGY OPPORTUNITY

When the facilities team at Towers School in Kent discovered that one of their teaching blocks had a leaking flat roof, the immediate priority was to stop the water ingress and protect the building. But as they reviewed the condition of the roof, they saw a wider opportunity. The project could not only address the building’s maintenance needs but also contribute to the school’s long-term sustainability goals.

At a time when many schools face rising energy costs and mounting pressure to decarbonise their estates, Towers School’s approach reflects a broader shift towards more integrated, value-driven refurbishment.

The decision was made to take a joined-up approach, combining the roof refurbishment with a solar pv installation. The aim was to improve thermal performance, reduce carbon emissions, and stabilise energy costs through on-site generation. Working with building surveyors Carré Building Consultancy and technical experts from Garland UK, the school developed a single, integrated project that would deliver measurable performance improvements and financial returns.

A COORDINATED APPROACH FROM DESIGN TO DELIVERY

From the outset, the focus was on coordination and accountability. Rather than treating the roof and solar works as separate contracts, the school wanted a single delivery partner who could design, oversee and guarantee both systems together. That decision shaped the entire project, removing the usual complexities that arise when

Sam Rigden, Technical Manager at Garland UK, carried out detailed surveys and design work to specify a new waterproofing and insulation build-up using its StressPly Flex Plus bituminous membrane system. The solution was selected for its long service life, robust mechanical strength, and high thermal efficiency. The upgraded roof achieved a U-value of 0.18 W/m²K, significantly enhancing the building’s energy performance and reducing heat loss across the block. Once the new waterproofing was in place, a bespoke Solarise photovoltaic system was installed, designed and engineered to integrate seamlessly with the roof structure.

MEASURABLE REDUCTIONS IN ENERGY AND CARBON

The outcome has been immediate and quantifiable. The solar array now generates over 40,000 kilowatt hours of clean electricity every year, offsetting a significant portion of the school’s grid consumption. The system is estimated to save over £13,000 in first-year energy

costs and prevent over 17 tonnes of carbon dioxide emissions each year. The combined investment has delivered a payback period of just 4.5 years, meaning the system will continue to provide cost and carbon savings for decades after it has paid for itself.

For the school, these figures represent more than just operational savings. They are evidence that sustainability-led refurbishment can be financially viable within tight public-sector budgets when projects are properly integrated and technically assured. The improved roof insulation reduces heating demand throughout the winter months, while the solar generation cuts reliance on grid power, particularly during daytime teaching hours. Together, these improvements have delivered measurable reductions in both energy use and operational carbon, with minimal disruption to teaching activities.

DIGITAL OVERSIGHT AND ASSET MANAGEMENT

A key factor in maintaining quality and performance throughout the project was Garland UK’s technical

oversight. Site inspections were carried out twice weekly during the works, ensuring that every element of the design specification was met. All activity was recorded through Garland’s digital Roof Asset Management Programme, known as RAMP, which provides clients with live project data, photographs, and inspection records. This digital record now forms part of the school’s ongoing asset management system, helping the estate team plan future maintenance and monitor performance over time.

REMOVING RISK THROUGH SINGLE-POINT ACCOUNTABILITY

Perhaps the most distinctive feature of the Towers School project is the approach to warranty and risk. The school’s roof and solar systems are protected under Garland UK’s Single-Point Guarantee, which covers both design and installation across the full system. In practical terms, that means the school has one source of accountability for the performance of the entire installation. If an issue arises, whether with the waterproofing or the PV array, the estate team contacts Garland directly. There is no division of responsibility or dispute between manufacturers and contractors over

which component is at fault. For estate managers managing large and complex property portfolios, this level of clarity can significantly reduce administrative burden and future risk exposure.

By capturing the full project history in one digital platform, the school’s estate team can now manage its roof assets more proactively, a model increasingly relevant to public-sector estate strategies.

A MODEL FOR SMARTER ESTATE INVESTMENT

This project illustrates a growing shift in how energy and estate managers are approaching capital works. Rather than delivering single-issue repairs, many organisations are beginning to combine building fabric upgrades with renewable installations to maximise return on investment and reduce disruption. Integrated refurbishment provides an efficient route to net zero, improving energy performance, extending asset life and supporting financial resilience.

By aligning the refurbishment of existing assets with sustainability objectives, the school has achieved long-term energy and carbon savings, improved the resilience of its estate, and enhanced the learning

environment for its students. It stands as a model for other schools and public-sector organisations facing the dual challenge of maintaining ageing infrastructure while advancing towards decarbonisation.

BUILDING FOR THE LONG TERM

For the education sector in particular, the lessons are clear. Sustainable refurbishment does not have to mean large-scale new builds or disruptive installations. By integrating roof, fabric, and renewable technologies within one coordinated design, estate managers can unlock efficiencies, extend the life of existing assets, and deliver measurable outcomes that support both operational and environmental goals.

Towers School’s project demonstrates the potential of integrating condition improvement and energy generation in a single programme, an approach that combines cost efficiency with measurable sustainability outcomes. It’s a reminder that sometimes the most powerful route to decarbonisation starts not with new technology, but with a smarter, joined-up way of thinking about the buildings we already have. www.garlanduk.com

WHY ONE-WAY HEDGING NO LONGER WORKS IN TODAY’S ENERGY MARKET

For years, energy procurement strategies could rely on a simple model: hedge forward, lock in price security, and minimise exposure to volatile spot markets. That approach no longer fits the realities of today’s energy landscape. Market dynamics have fundamentally shifted. Price movements are now larger, more frequent, and harder to predict. The traditional belief that locking in a fixed forward price guarantees stability and competitive advantage is increasingly challenged by multi-year evidence – particularly when falling market prices mean the benefit of cover is forfeited. In addition, forward hedging carries an embedded premium, much like paying for insurance, which often results in a higher cost than simply taking market outcomes over time.

THE PROBLEM WITH ‘SET-AND-FORGET’ HEDGING

Many corporate energy buyers are left with a binary choice:

• Fix all volumes

• Float all volumes

• Or attempt a static mix between the two

In practice, this leaves procurement teams with a narrow toolkit. It is easy to fall into the ‘habit’ of hedging mechanically on a year-byyear basis, constrained by what solutions are available from their suppliers or advisors. But when we examine the outcomes across the last 10 years, a pure forward-hedging strategy performs the worst of all approaches tested

In our analysis, we compared four strategies over multiple years:

1. Fixed: hedge everything at the average forward price (i.e., based on an average of how the market valued the ‘front year’ in the preceding year e.g. the daily value of 2015 during 2014)

2. Float: expose everything to realised spot prices

3. Flexible protection policy: activate coverage when market prices rise to a predetermined trigger, calibrated to the average forward cost, while paying a premium

The findings are striking:

Pure forward hedging produced the highest cost outcome

Pure floating had lower average costs, but with extreme volatility – a strategy few corporates would accept

Hybrid policy – pre-set triggers with flexibility, meaningfully improved resilience and cost outcomes

Michael Doherty, Director of Structured Solutions and Origination, Paratus

Why?

In 6 out of 10 years analysed, the realised price was lower than the forward price-hence it was a better strategy NOT to hedge in these years

• However, in some years e.g., 2021 the realised price was more than double what a buyer could have hedged it at the year before

• Before collapsing again, the next year to ~33% of the forward valuation

• Overall, there is no one size fits all strategy but being overly conservative can be value destructive in the long run

A NEW HEDGING PARADIGM: FLEXIBILITY OVER RIGIDITY

The conclusion is clear – A one-way, always-hedge procurement strategy is not fit for purpose in this volatile market.

Energy consumers need optionality, the ability to move between fixed and floating exposure as conditions change. This requires:

• Forward hedging frameworks enriched with market context

• Trigger-based risk overlays

• Tools that allow dynamic decision-making instead of static annual hedges

This is the direction sophisticated market participants are already moving. Our goal now is to broaden access to these insights and support procurement teams that are time-constrained and under-resourced, yet responsible for billions in energy spend.

THE MESSAGE TO ENERGY BUYERS IS SIMPLE:

In volatile markets, flexibility isn’t optional, it’s a competitive necessity.

The results from our analysis of Bloomberg forward curves and N2EX baseload prices are clear: strategies that maintain some exposure to actual market prices consistently outperform rigid, single-track hedging policies. The market is simply too unpredictable for a one-way strategy to be fit for purpose.

Our analysis also shows that over a 10-year horizon, an insurance approach finishes approximately £10 per MWh better off – factoring in the full cost of the policy. This equals to £1 million per annum for a 100,000 MWh portfolio. In other words, flexibility doesn’t just reduce risk – it delivers value.

For those interested in exploring the modelling, assumptions, or results in more detail, our team would be pleased to walk through the analysis.

In today’s energy environment, flexibility is a measurable advantage. www.paratusltd.com

Q&A with Neil Garland, Head of Origination at Evolve Energy

Why are Corporate Power Purchase Agreements (CPPAs) becoming more relevant to UK businesses right now?

Demand for CPPAs in the UK is growing rapidly as businesses face tougher ESG reporting rules, volatile energy prices and rising energy demand across industries from data centres to pharmaceuticals and retail. Traditionally, CPPAs were the preserve of large energy companies and multinationals with the resources to navigate their complexity. Today, the landscape is shifting. CPPAs are becoming more accessible, opening the door for a far wider range of industrial and commercial businesses to access secure, traceable renewable power. For many businesses, CPPAs now represent a strategic opportunity to stabilise costs, reduce emissions and strengthen their long-term competitiveness in an increasingly challenging energy market. What’s driving this surge in interest?

A combination of environmental, regulatory and market factors has fuelled this surge. ESG reporting requirements, such as the EU Corporate Sustainability Reporting Directive, now mean companies must prove their own energy use and that of their supply chains are sustainable. Scope 3 emissions, linked to these rules, have become critical in competitive tenders and compliance with initiatives like the Science Based Targets initiative. At the same time, energy price volatility is hitting hard. In January 2025, UK wholesale electricity prices soared to £250 per megawatt hour. Europe’s gas reserves are also under strain, standing at 56.6% in June 2025 compared to

75.5% a year earlier. Falling CPPA prices and record renewable generation in 2024 are now driving businesses toward long-term price stability.

Despite this demand, why are CPPAs still difficult for many industrial and commercial businesses to access?

The barriers to entry remain high. Developers of new renewable projects typically seek long-term contracts of 10 to 15 years to secure financing. For many businesses, this horizon doesn’t align with their energy planning cycles.

Competition from the government’s Contracts for Difference (CfD) subsidy scheme also plays a role. CfDs guarantee generators’ revenues, making them reluctant to offer shorter, more flexible CPPA terms and often pushing prices higher.

Credit is another challenge. Many developers only work with investmentgrade buyers. Others require cash collateral or Letters of Credit, which can tie up significant capital. CPPAs are also complex legal agreements, requiring extensive review and sleeving arrangements with licensed suppliers to integrate renewable energy into existing supply contracts. The process can take months or even years, discouraging smaller businesses from participating altogether.

What changes are needed to make CPPAs more accessible and affordable?

Simplification is key. The CPPA market needs to reduce both complexity and cost if it is to attract a broader range of businesses. Standardising terms and conditions would make agreements

easier to understand and faster to negotiate, helping to cut down on lengthy legal processes and associated costs.

Lowering credit barriers would also be transformative. Many businesses cannot meet the current credit requirements, and alternative structures are needed to give them a fair chance to participate. Finally, licensed suppliers and generators need stronger incentives to collaborate, so renewable power can flow smoothly from generator to buyer without excessive contractual hurdles.

Are there any examples of how the market is already evolving in this direction?

Encouraging signs are emerging. Renewable energy consortiums are one example, enabling companies to pool demand and share the benefits of a CPPA without bearing all the risk individually. This goes beyond simply purchasing Renewable Energy Guarantees of Origin certificates, offering genuine time-matching between renewable generation and consumption.

Some CPPAs now use supply licence exemptions, such as Class A, allowing smaller generators to supply up to 2.5 megawatts per half-hourly settlement period when matched directly to demand. This avoids certain government policy and social costs, making renewable energy more affordable for both sides.

Looking ahead, what needs to happen for CPPAs to become mainstream across the industrial and commercial sector?

Traceable green energy is becoming a critical requirement as businesses face mounting pressure from regulators, supply chains and their own net zero commitments. The rewards of a mature CPPA market are clear: greater transparency of emissions, accelerated carbon reduction and long-term price stability.

To achieve this, the current system must give way to a more open and standardised model. Generators need to align on common terms and conditions, making contracts simpler and quicker to finalise. Making renewable power affordable and accessible will not only accelerate the energy transition but also give UK businesses the tools they need to thrive sustainably in a competitive global market. www.evolve-energy.com

NON-COMMODITY COSTS: WILL BUSINESSES PAY THE PRICE FOR CLEAN POWER?

The UK’s energy market is undergoing rapid change as clean power moves from ambition to reality. While businesses have become accustomed to understanding and managing the volatility of commodity prices, rising non-commodity charges now represent a more pressing challenge.

Delivering the scale of renewables to meet the UK’s clean power targets means building significant new infrastructure to connect and transport power. Around 5,500 kilometres of new grid capacity is needed in the next five years, more than double what has been built in the past decade.

However, this transformation comes at a cost. Every business in the UK is now facing a sharp increase in non-commodity costs, which will help fund the infrastructure needed.

Given this context, it is perhaps not surprising that energy remains the top risk businesses are facing for the fourth year running, according to our Business Energy Tracker 2025, which draws on data from over 130 large energy users.

The report revealed that 79% of businesses predict their energy costs will rise over the next 12 months and more than half (54%) say they are having a negative impact on business confidence.

In addition, 97% of businesses surveyed said they are worried about the financial impact of the low-carbon transition, while half believe that non-commodity costs are unfair.

That said, while many respondents noted that standing charges have increased across their portfolios over the past year, there was support for the clean power mission. Many understood the benefits it would bring, and more than half (57%) also understood that they will need to bear some of the costs for the low-carbon transition.

So, where are these increases coming from?

Three charges in particular are likely to be impacted:

• Contracts for Difference (CfD) provide renewable generation developers with a guaranteed price for power, ensuring new projects are financially viable. It is central to delivering Clean Power 2030, but

Stephen Evans, Industry Costing Manager on the Optimisation Desk, nBS

comes at a cost. CfD charges could rise from around £10/MWh today to nearly £30/MWh by 2030.

• Transmission costs will also rise. With the network needing to grow four times faster than in the last decade, operators expect their investment to double. For businesses, that means annual charges could also double. A customer in the lowest high voltage band, for instance, could see costs increase from £8,000 in 2025/26 to £25,000 by 2030/31.

• Balancing costs are also likely to increase. These cover the cost of ensuring supply meets demand and are already heavily influenced by constraint costs, the payments to generators who cannot sell their output because the grid cannot accommodate it. Unless the grid expands in step with renewables, balancing costs could rise from £12/MWh now to around £20/MWh by 2030.

MANAGING THE NON-COMMODITY RISK

While organisations cannot control policy or infrastructure costs, they can take steps to reduce their exposure. The Business Energy Tracker revealed that energy efficiency remains the top priority for managing risk, with 71% of respondents focusing on it as their primary strategy. For larger businesses with an annual energy spend of over £1 million, investing in on-site generation was another key measure, with 40% looking to make this investment. Other measures included using energy management tools (40%), shifting energy demand to off-peak times (40%), switching to renewable energy (34%) and appointing an in-house energy specialist (32%). For us, there are four ways that businesses can limit the impact of rising non-commodity costs:

1. Reduce your energy consumption: while it’s difficult to control your

non-commodity costs, you can control your energy consumption. Investing in energy efficiency and other energy reduction measures can have a positive impact on the amount you pay for energy.

2. Consider on-site generation: any energy installed behind-the-meter (BtM) is not subject to industry costs such as Balancing Services Use of System (BSUoS), CfD or Capacity Market (CM) charges.

3. Reduce your network capacity: if you are able to do this, then you can reduce your Distribution Use of System (DUoS) and Transmission Network Use of System (TNUoS) charges.

4. Load management: this can be an effective way to reduce peak CM costs.

BUILDING A CLEAN POWER SYSTEM THAT WORKS FOR ALL

The transition to clean power is an absolute necessity. However, the Business Energy Tracker shows that the concerns about the short-term cost of the delivery and the impact this could have on confidence and competitiveness, are very real and need to be addressed. We’re ready to work with the government to ensure that, while we build a cleaner and more stable energy system, businesses receive the right support to ensure they remain competitive now and in the future.

AI MOVES TO THE FRONTLINE OF ENERGY MANAGEMENT AT EMEX 2025

ClearVUE debuts IRIS and previews Flexer inside ClearVUE.Zero

Visitors to EMEX will see ClearVUE bring decisiongrade intelligence to the point of use. On stand B20, the team will introduce two additions to ClearVUE.Zero that work in tandem: IRIS, a plain-English assistant for understanding what’s happening across your estate, and Flexer, a co-pilot for purchasing that weighs market signals against the position you already hold. Together they sketch a single path from “what’s driving our usage?” to “what should we do next?”, without piling more manual analysis on already thin teams.

IRIS focuses on the questions that slow progress. Which sites are pulling the numbers up? What changed and when? Where is waste likely, and how do we prove a fix actually worked? Ask, and IRIS responds with a ranked view and

the evidence behind it, drawn from the data you already collect in ClearVUE.Zero. It helps capture actions with an owner and an expected impact, then provides a simple way to confirm results against a baseline. For newcomers, an anonymised gallery of saved prompts shows how peers approach common problems, so you’re never starting from an empty page. The aim is straightforward: less time unpacking data; more time acting on it.

Flexer brings the same discipline to the buying side. Working inside ClearVUE. Zero, it reads your consumption shape and current position alongside live wholesale prices to show where cover is strong or thin and what that means for delivered cost. From there it frames the next moves in the language of your policy, so decisions can align to your risk rules rather than impulse. Flexer also prepares the housekeeping around those decisions (summaries for review, supplier requests, and a concise renewal pack) so approvals aren’t held up by admin. Because it shares a data foundation with IRIS, operational changes and efficiency plans can be reflected in the cost picture instead of left to assumption.

On stand, the demonstrations keep the focus on the decision path, not a feature tour. You’ll see a question posed, the figures that matter returned, and a prepared next step with the reasoning behind it. The sessions are short by design and meant to start conversations about your estate, your budgets and your risk appetite. If you want to go deeper, the team will show how insight and purchasing dovetail, enough to understand what’s now possible, without giving the whole playbook away.

ClearVUE’s view is simple: monitoring alone doesn’t change outcomes. Interpretation and well-timed action do. IRIS and Flexer are built to close that gap where most initiatives stall, and to leave a clear record of what changed and why.

WHERE TO SEE IT

EMEX 2025, ExCeL London, Stand B20. Demonstrations daily at 11:30 and 14:30. Book a slot: https:// clearvue.business/emex-form/

HOW HVAC APPLIANCES CAN CONTRIBUTE TO GRID-INTERACTIVE BUILDINGS

Grid-interactive buildings utilise smart technologies and connected systems to optimise energy use and interact with the electricity grid. This new generation of smart buildings is transforming energy management, helping to deliver much greater energy flexibility. Used increasingly in energy flexibility programmes, they offer efficiency for users, and cost savings.

Importantly, they can actively contribute to balancing the supply and demand of energy, reducing strain on the grid.

These ‘intelligent’ buildings – mostly commercial but residential as well –can adapt energy use dynamically. Instead of playing a passive role in simply drawing down energy, they reduce demand when the grid is under stress, particularly during peak use.

THE GROWING IMPORTANCE OF DISTRIBUTED ENERGY SOURCES

By storing and drawing power from different distributed energy resources (DER) buildings like this treat electric appliances and systems as potential grid resources.

When we talk about DER, this might include heat pumps, water heaters and other heating, ventilation and air-conditioning (HVAC) systems and appliances or more often today, renewable energy sources like solar PVs, battery storage, or electric vehicles. In commercial buildings, Building Energy Management Systems or BEMS can aggregate these DERs.

Smart buildings and connected homes and technologies are not new of course. We’ve seen talk of development around this for a while. But recent advances in grid connectivity and standards, and more recently, the integration of AI for smart automation, have accelerated these developments.

What we are now seeing are more use cases where grid-interactive buildings are enabling the localisation, generation and consumption of energy, while working around the bottlenecks in the distribution network.

THE ROLE OF INDUSTRY STANDARDS

As an industry alliance that represents both manufacturers and users of HVACR products, and increasingly BEMS, the OpenADR Alliance is witnessing innovation in action. The adoption of these new technologies is driving this progress with the potential to unlock other benefits.

Standards play a crucial role in driving this innovation, particularly in enabling efficient demand response within energy management systems, while governments and regulatory bodies support this by mandating these standards.

In the US, the CTA-2045 specification (also known as the certified version EcoPort) enables smart appliances and devices to connect directly to energy management systems (commercial or residential) through a universal port. This interoperability promotes flexibility and adaptive energy consumption across appliances, playing a crucial role in encouraging customers to adopt greener practices.

Don Dulchinos, Director, OpenADR Alliance

solutions, including the development of ESA for the delivery of interoperable demand side response as part of its program.

EARLY IMPLEMENTATIONS

Any EcoPort-certified control module, when plugged into an appliance or building energy management system, can reliably establish communications that meet the requirements of the CTA-2045 standard.

The UK has followed suit, with two standards published in 2021 – PAS 1878 and PAS 1879 – setting out the requirements for energy smart appliances (ESA). The Department for Energy Security and Net Zero (DESNZ) led the development of PAS 1878, incorporating OpenADR as one of the criteria that an electrical appliance must meet to perform and be classified as an ESA. PAS 1879, on the other hand, addresses the demand side response operation of these appliances.

DESNZ has emphasised the significance of innovation in smart technologies in their ambitions to reach net zero by 2050 – and the role standards will play in driving this transformation.

The government’s Flexibility Innovation Program is also contributing to this effort by supporting innovative

Particularly in the US, these are largely restricted to water heaters, a major source of load response across households. EcoPort provides a standard interface for energy management signals and messages, enabling communication with various devices, such as building energy management hubs, residential gateways, sensors, and more unlikely candidates like pool pumps and EV chargers.

A real-world example is in Oregon, where utilities have implemented OpenADR programs using certified, CTA-2045 equipped devices. Local utilities have focused on compliant smart water heaters and HVAC, which temporarily reduced energy consumption during periods of high demand. This has resulted in a significant reduction in peak demand during hot summer days, taking the pressure off the grid and ensuring customers maintained a comfortable environment.

The success of these sorts of programs demonstrates the huge potential for similar initiatives. By using technology and fostering greater collaboration between governments, energy providers, product manufacturers, and customers, there’s an opportunity to create a positive energy future.

With the growing range of products and systems now available, grid-interactive buildings are on course to become a major contributor to this. www.openadr.org

LIMESCALE PROTECTION IN COMMERCIAL HEATING & HOT WATER SYSTEMS – THE NUMBERS THAT ADD UP TO SIGNIFICANT SAVINGS

Rinnai’s Chris Goggin looks in detail at the cost savings in both time and energy costs that comes with effective scale protection to all systems.

Limescale within the heating & hot water systems at commercial sites across the UK is a common problem associated with hardwater areas. About 60% of mains water supplied in the UK is classified as ‘hard’ and this produces limescale deposits which reduce the efficiency of heating & water-heating appliances and systems. This means increased operating costs. Just 1.6mm of scale can reduce system efficiency by 12%. This leads to greater costs on energy fuels and site time through remedial works combatting the limescale.

The existence of limescale, in a heating & hot water system, simply adds a significant cost. These repercussions from limescale build up can have a lot of negative outcomes, but most importantly it has significant effects on reducing the efficiency of water heating technology, in turn increasing the amount of energy needed to be consumed to meet hot water demands within commercial buildings.

Limescale increases the energy consumed as it impedes the heat transfer efficiency of plate heat exchangers, water heaters, and other

technologies, therefore, forcing this technology to input more energy to retain the same level of performance.

This report aims to highlight the expected operating expenditure (OPEX) and carbon production savings when installing scale protection, compared to various thicknesses of scale buildup within DHW systems.

Industry studies show the figures regarding the percentage increase in energy usage as the thickness of scale increases.

Excel 19-20 November 2025

To conduct this study a gas system was sized for each archetype. The systems modeled for the sites are:

• Small hotel – 2 x N1600 + 300L storage

• Medium hotel – 6 x N1600 + 800L storage and

• Large hotel – 16 x N1600 + 2000L storage, respectively.

The purpose of comparing different sized hotels is to show how the expected OPEX and carbon production savings increase as the size of the commercial building increases. This shows that scale protection is important for every system in a hard water area, and that the importance of this protection increases as the system size and hot water demand increases.

For the three star small hotel measured over a 10-year period as the thickness of scale increases from having no limescale to having 4mm of limescale results in showing that for every mm increase in limescale, the carbon production increases by 14,978kg CO2. Therefore, if scale increased to 4mm, the system would produce an additional 59,912kg CO2 compared to a fully protected system.

The output is similar from an operating costs perspective. For every mm increase in scale thickness, the operating cost to run the DHW system, for a small 3 star hotel, increases by £3,200. While if the scale thickness increases up to 4mm, the increase in costs totals to £12,799 over a 10-year forecast period, which is a percentage increase of 28%.

The second case study looks at a medium sized hotel and a higher star rating, which suggests higher hot water demand. This increase in hot water demand along with increased scale thickness portrays even higher carbon production and operating costs differences compared to a fully protected DHW system.

Results here show that for every mm increase in scale within a DHW system, the increase in carbon production and operating costs is 40,864kg CO2 and £8,829, respectively. Therefore, when

comparing a fully protected system to a system with a scale buildup of 4mm it shows forecasted carbon and OPEX savings of 163,465kg CO2 and £34,677 over a 10-year forecast period.

The final case study looks at the top of the range, large 4 star hotel, as means to highlight how important scale protection is as a site’s hot water demand grows. As seen by the graphics one & two, the increase in carbon and OPEX per mm of scale build up is 101,793kg CO2 and £21,820, respectively. Therefore, comparing a DHW with 4mm of scale to a fully protected system with no scale, the expected savings for an archetype hotel of this size for carbon and OPEX, over a 10-year period, are 401,049kg CO2 and £86,684, respectively.

IN SUMMARY – WHY PREVENT AND PROTECT FROM LIMESCALE BUILD UP?

• Increases energy efficiency: Improves heat transfer, which will lead to lower fuel consumption.

• Lowers maintenance costs: Extends the life of equipment and reduces the need for manual cleaning.

• Improves water quality: Cleaner surfaces in pipes and fixtures lead to better water hygiene.

Rinnai offers a range of products preventing limescale build -up and has a close working partnership with AQUABION®, a patented galvanic and electrolytic solution in a self-cleaning package. In this process, minute amounts of high-purity zinc ions are released and react with calcite. Calcite crystals are modified into adhesion-neutral aragonite, which is simply discharged into the water. Different to other water treatment units the patented AQUABION® operates without current, chemicals or magnets. The two swirling chambers each upstream and downstream agitates the water and is responsible for the self-cleaning effect of AQUABION® units themselves. AQUABION® is both chemical and electricity free and is a fully recyclable water treatment system enabling both end users and water treatment providers to tackle the problems of limescale without impacting the environment. It serves as a viable alternative to a commercial water softener with its environmental benefits. Visit www.rinnai-uk.co.uk

REDUCING EMBODIED CARBON IN VENTILATION SYSTEMS: A CRITICAL STEP TOWARD NET ZERO

As the built environment accelerates its transition toward net zero, the industry’s attention has rightly shifted from just operational efficiency to whole-life carbon emissions. While energy efficiency remains crucial, reducing embodied carbon – the emissions associated with the production, transportation, installation, and disposal of building materials – has become an urgent priority. Among these materials, mechanical, electrical, and plumbing (MEP) systems are estimated to account for around 23% of a building’s embodied carbon. As developers, specifiers, and manufacturers align with Science-Based Targets and upcoming regulations, the HVAC industry faces a clear mandate: reduce embodied carbon without compromising performance, reliability, or indoor air quality.

EMBODIED CARBON: THE OVERLOOKED CULPRIT

Traditionally, much of the building industry’s focus has been on operational carbon – the emissions generated during the use phase of buildings. However, embodied carbon can account for 20-50% of the total lifecycle emissions of a building, depending on usage type and design. As operational carbon is reduced through improvements in building efficiency and renewable energy adoption, the relative impact of embodied emissions becomes even more significant.

For ventilation systems, this challenge is particularly nuanced. These products are essential for indoor air quality, thermal comfort, and regulatory compliance. Their complexity, the materials used (primarily steel and plastics), and the necessity for durability make decarbonisation more difficult – but not impossible.

THE ROLE OF MATERIAL INNOVATION

Reducing embodied carbon in HVAC systems begins with material choices. Steel, a staple material in commercial ventilation units, is a major contributor to embodied carbon due to the energy-

intensive processes involved in its production. Similarly, plastics used in residential systems and ducting often rely on virgin fossil-based polymers.

Progress is being made. One promising development is the transition to low carbon-emissions steel made using recycled content and renewable energy sources. Recycled and renewably produced steel, such as XCarb® from ArcelorMittal, dramatically lowers the carbon footprint of HVAC components. For context, this steel has an embodied carbon footprint of just 0.898 tCO2e per tonne, compared to 2.51 tCO2e for conventional steel.

Nuaire is the first UK ventilation manufacturer to switch to this innovative steel across several high-volume commercial products, including our BPS air handling units and XBOXER XBC packaged heat recovery systems. This shift will result in a 64% reduction on the steel proportion of our SCOPE 3 embodied carbon activity within the first year alone, compared with the same steel manufactured via the conventional steelmaking route.

Plastics present another opportunity for carbon savings. The casing material in our Drimaster-Eco Positive Input Ventilation (PIV) units was recently

switched from virgin ABS plastic to 100% recycled plastic, reducing carbon by 167 tonnes each year. The only noticeable change for customers is a shift in the product’s external colour –from blue to black – highlighting that sustainable change needn’t sacrifice function or form. We have also changed to recycled plastic for our ducting, and implemented careful material reduction and other material substitution, which removed 2,000 tons of carbon from our product portfolio in 2024 alone.

MEASUREMENT, TRANSPARENCY, AND ACCOUNTABILITY

Reducing embodied carbon is not only about making better material choices – it also requires transparency and standardisation in measurement. Without consistent, verifiable data, designers and clients struggle to assess and compare options across product categories.

To support this need, manufacturers need to provide CIBSE TM65-compliant embodied carbon assessments, which estimate the emissions associated with HVAC products from raw material extraction to end-of-life. These datasheets allow specifiers to make informed decisions, balancing carbon

performance with cost, efficiency, and compliance requirements.

Nuaire, as part of our broader carbon strategy, now provides TM65 datasheets for the majority of our product range. This helps consultants and developers incorporate embodied carbon metrics into Building Information Modelling (BIM) and lifecycle assessments, offering clarity and comparability that have long been missing from HVAC procurement decisions.

SCALING IMPACT

THROUGH COLLABORATION

Transformative change doesn’t happen in isolation. The HVAC sector’s decarbonisation journey will require deep collaboration across the supply chain. Nuaire’s partnership with Steelco, a UK steel supplier, and ArcelorMittal is a case in point. These long-term relationships enabled the early adoption of XCarb® steel and demonstrate how joint innovation between manufacturers and material suppliers can fast-track progress. It also reflects a growing understanding that supply chain emissions (Scope 3) are where many

companies must now concentrate their efforts. By working closely with suppliers to validate Environmental Product Declarations (EPDs), manufacturers can help drive broader systemic change across the industry.

FROM LEADERSHIP TO INDUSTRY STANDARD

As regulatory pressure grows – such as potential embodied carbon caps and whole-life carbon assessments becoming mandatory in future UK building regulations – early adopters will set the standard for the rest of the market.

However, beyond compliance, there is a broader imperative. The climate crisis demands more than incremental change. By tackling embodied carbon in ventilation systems, the HVAC sector has a real opportunity to lead by example – delivering healthier buildings that don’t cost the earth.

CONCLUSION: A NEW CARBON PARADIGM

The road to net zero is not a straight one, and it certainly doesn’t end with energy efficiency alone.

Reducing embodied carbon in ventilation systems is both a technical and ethical challenge – one that calls for innovation, transparency, and industry-wide commitment.

Material innovation, such as the adoption of low-carbon steel and recycled plastics, is a crucial first step. So too is the development of measurement frameworks like TM65, which allow decision-makers to prioritise carbon performance alongside traditional criteria.

As more manufacturers more toward low-carbon products, and as demand from developers, architects, and occupants continues to grow, the ventilation systems of tomorrow will be defined not only by how efficiently they move air – but by how responsibly they are made.

BUILDING A GREENER NHS: HOW DECARBONISATION AND SMART HOSPITALS CAN TRANSFORM

HEALTHCARE ESTATES

At the Convenzis NHS Sustainable Solutions Conference, Equans Regional Director for Healthcare, Simon Hayman, highlighted the pressing challenge facing NHS Trusts: how to decarbonise, adapt to climate change and improve the air quality for its communities, while managing ageing estates, complex PFI agreements, and limited budgets.

The NHS is leading the way with regards to its carbon emissions targets, but the message is clear – decarbonisation is no longer optional. It is essential to building resilient, affordable, and sustainable healthcare estates that can support patient needs now and in the future.

A PROVEN FIVE-STAGE ROADMAP

Equans have developed a tried and tested five-stage decarbonisation roadmap that gives NHS Trusts a practical framework for action. It begins with data –understanding where emissions come from and how buildings are used. This data-driven approach enables smarter decision-making and highlights opportunities for immediate behaviour change, such as temperature management and building management system optimisation.

The roadmap then focuses on understanding contracts, engaging stakeholders, and prioritising interventions before moving into detailed, costed plans developed by the Carbon Shift team. These are broken down into ‘off-the-shelf’ packages that can be quickly tailored for funding bids or contract variations. In a landscape where funding timelines are tight, this readiness is a real advantage.

TURNING STRATEGY INTO REALITY: CASE STUDIES

Simon showcased real-world examples of how this roadmap is already helping Trusts decarbonise.

• All-electric hospitals: the UK’s first fully electric healthcare estate, Oriel eye hospital in London (opening 2027) and all-electric stand-alone diagnostic centre at West Middlesex University Hospital (2028) are being delivered by Bouygues UK, and Equans are delivering a full retrofit of Pontefract hospital PFI building (from 2028). These projects combine electrification of heating and hot water

with thermal storage, solar power, and battery energy storage to create resilient, low-carbon estates enhancing the air quality for the patients and communities.

• District heating networks: In North West London, with PSDS funding withdrawn, Equans is working with its client on a PFI Hospital to access the Green Heat Network Fund (GHNF). By combining GHNF support with match funding, Trusts are able to proceed with low-carbon heat solutions despite a challenging funding environment.

• Smart hospitals: In Canada, Equans have already delivered 12 smart hospitals through Plan Group. In the UK, Oriel will become the first of its kind.

OVERCOMING

FUNDING BARRIERS

One of the greatest challenges for Trusts remains access to capital funding. The closure of the Public Sector Decarbonisation Scheme (PSDS) has created gaps in financing. When opportunities do arise, the window for applying is often tight, meaning Trusts must be ready to act quickly. Equans' decarbonisation offer is designed to meet this need. By preparing detailed business cases in advance, Trusts can move at pace when funding becomes available. Simon stressed the importance of early engagement with DHSC, so that bids are viewed favourably before they even land. Adapting existing PFI contracts also creates opportunities. By integrating decarbonisation into lifecycle and asset management, Trusts can unlock long-term value and resilience without waiting for grant funding.

BEYOND CARBON: AIR QUALITY AND TRANSPORT

Decarbonisation is not just about reducing emissions – it’s also about creating healthier environments for patients and staff. The Royal College of Physicians has

been clear, there is no safe level of air pollution, and action is urgently needed.

Equans are tackling this on multiple fronts. Alongside electrification of estates, they are investing in sustainable transport solutions, from EVs to e-cargo bikes. With more than 1,400 vehicles now fully electric, and hospitals like Oriel set to be powered 100% by electricity, the link between decarbonisation and improved air quality is becoming stronger every day.

THE PROMISE OF SMART HOSPITALS

A key theme of Simon’s session was the emergence of smart hospitals. These are not simply ‘smart buildings’ – they are connected, adaptive environments that put patient care at the centre of design.

Smart hospitals use technology to improve patient flow, space utilisation, and staff responsiveness. They allow Trusts to measure and improve KPIs such as patient satisfaction, waiting times, and staff productivity. Crucially, they also deliver measurable carbon savings and energy efficiencies.

Equans supports Trusts beyond the construction phase with a ‘soft landing’ approach, ensuring NHS teams are ready to use digital systems effectively. By aligning KPIs for both patient care and sustainability, smart hospitals represent a genuine step-change for the NHS.

BUILDING CLIMATE RESILIENCE IN HEALTHCARE ESTATES

The journey to net zero in healthcare will not be easy. But with proven roadmaps, smart funding strategies, and digital innovation, it is possible to deliver estates that are efficient, resilient, and patient-focused.

Equans are committed to supporting NHS Trusts every step of the way, from data collection and behavioural change through to electrification, smart hospital delivery, and sustainable transport.

As Simon concluded, the NHS has an opportunity to lead the way in building climate resilience across the public sector. With the right partnerships and a commitment to innovation, a greener, healthier NHS is within reach. www.equans.co.uk

RINNAI AND KIMPTON DELIVER ZERO-DOWNTIME HOT WATER SOLUTION FOR SPIRE MURRAYFIELD HOSPITAL

Request a free brochure today on the Rinnai range of high efficiency, future proof continuous flow water heaters. www.rinnai-uk.co.uk/ contact-us/request-brochure

Kimpton, the Liverpool and Northwest-based HVAC specialist contractor, has supplied and installed the Spire Murrayfield hospital in Barnston, Wirral with an emergency replacement Rinnai hot water heating system after the site’s gas fired storage water heaters failed to operate.

Replacing the hot water heater system meant that the hospital could continue supplying daily care to the community without interruption to medical continuity. The hospital produced its hot water for the X Ray and other departments via a single gas fired storage water heater. When this unit failed, an urgent response was required to ensure continuity of supply for patients and staff.

Kimpton offers temporary boiler and water heater hire, so this was the first port of call. Within a few hours the problem had been isolated, and the new temporary boiler set had been installed to ensure zero downtime. This system was made up of two 58kW gasfired Rinnai water heaters on a simple skid. The temporary system had been designed by the team at Kimptons with support of Rinnai, so they were confident it would work exactly as required.

The finished system was made up of a buffer vessel and two higher efficiency Rinnai modulating gas-fired 20% hydrogen ready water heaters of 58kW each. This set up allows the system to regulate capacity as required and ensure both continuous flow water heaters are cycled evenly. The new system allows water to be raised in temperature from 20 degrees to its max of 65 degrees in only 15 minutes, so allows huge flexibility.

The project was managed by Paul Bowes and Stuart Dilworth from start to finish. Speaking about it, Paul said: “The whole project went well from the outset. Customers like Spire Murrayfield must be able to operate with zero downtime. Our temporary hot water heater system saved the day in this project and allowed

us to conduct the system upgrade with no dramas and zero downtime.”

The Rinnai instant hot water solutions are an ideal solution for mobile, temporary and heat for hire services as they are light weight (28kgs) high power (58kw) diminutive water heaters. Another added benefit is that they come with market leading warranties up to 12 years and can be easily set for LPG or NG dependent on site needs.

Sam Carson speaking on behalf of Rinnai stated, “It is a pleasure working with Kimptons and I am pleased that the easy fit, high flow rate nature of Rinnai appliances proved to be an ideal option for the hospital and my friends at Kimptons.”

Rinnai is global leader in hot water systems with 2M+ units produced annually. The gas-fired water heaters are hydrogen 20% blend ready and BioLPG ready, future proofing hire applications and many more. Rinnai also provide innovative heat pump and hybrid solutions for a wide range of commercial projects. Ensuring the supply of heating and hot water systems for multiple fuel sources and creating options for clients such as Kimptons.

Kimpton has been delivering M&E projects, commercial fit-out and

HVAC services across the Liverpool City Region since 1963. The company places great emphasis on M & E innovation. For example, for many, heat pump technology is new, but Kimpton began designing and installing heat pumps in 1974 when it helped Walkers Crisps and Golden Wonder solve the problem of how to make the stored potatoes last longer. By dramatically changing the length of time potatoes could be stored, it allowed them to buy potatoes when they were plentiful and, in its own way, revolutionised the UK’s potato crisp industry.

This culture of innovation has led to the delivery of two other UK firsts in renewable technology – Kimpton designed and installed the UK’s first water source heat pumps in open sea at Plas Newydd, Anglesey for the National Trust and installed one of the UK’s first Transpired Solar Collectors with TATA steel at the SBEC Building on Deeside.
