New Government Funding Creates Opportunity for Low-Carbon Social Housing, Says Baxi

Baxi is encouraging social housing providers to ensure they have robust clean heat strategies in place for both new build and refurbishment projects following funding announcements in the Spring Statement.

The call follows the government’s allocation of £2 billion to support the development of 18,000 new affordable homes, half of which is allocated for social housing. This funding for new build homes sits alongside the Warm Homes: Social Housing Fund in place to retrofit existing social housing and improve energy efficiency.

Rob Pearse, Residential Business Director at Baxi, said: “The £2 billion set aside for social housing in the Spring Statement must be used with sustainability in mind, which includes the long-term comfort and financial security of tenants as well as electrified heating. This can be achieved by working closely with manufacturers who have expertise in the sustainable heating of social housing and a raft of solutions able to match almost any requirements.

“Delivering clean heat in social housing sector can be challenging, and we intend to support providers from the earliest steps of their net zero journey. It is important to identify the system that delivers the best efficiency, cost and environmental results for the building and occupants. Working closely with experts and the wider supply chain can provide the expertise and solutions to do this successfully for both new build and retrofit.”

Air source heat pumps (ASHPs) are a key route to clean heat for both new build and retrofit social housing projects, though design challenges for retrofit and skills shortages for installers can be a barrier to social housing providers. To assist the sector with implementation, Baxi has developed a broad portfolio of heat pump solutions suitable for new build and retrofit, along with extensive training, commissioning services and customer support.

This includes new prefabricated pod options for new build and retrofit that bring the ASHP system into a pre-assembled unit, manufactured offsite by Baxi Packaged Solutions (BPS). Using Modern Methods of Construction (MMC) to deliver a more sustainable solution makes the installation significantly faster and simpler and removes the need for major modifications inside the home. This in turn makes low-carbon heating and hot water more accessible in social housing.

For larger developments and multiple occupancy buildings, Baxi‘s expert full-service heat network team offer support with design and implementation of end-to-end solutions, including social housing developments. Where zoning policy mandates that heat networks must connect to a larger scheme, consultation with experts, such as those at Baxi, can support a smoother integration with the wider network.

Rob said. “Achieving decarbonisation requires a combination of bespoke plans and expertise in heating and hot water solutions.

“At Baxi, we have the range of solutions to deliver on energy efficiency and net zero targets, along with the vital experience to support social housing providers in delivering clean heat across new build and retrofit. With the funding discussed in the Spring Statement, we are encouraging all social housing providers to stay ahead of the curve by exploring the solutions available for their projects.”

Energy Savings for Businesses – The Benefits of Solar PV and Battery Storage

In today’s fast-paced world, businesses are looking for sustainable ways to cut costs and reduce their carbon footprint. One popular solution is installing a commercial solar PV rooftop system with battery storage. This setup offers many benefits, such as saving money, increasing energy independence, helping the environment, and providing flexibility and efficiency in energy use.

By incorporating a commercial solar PV rooftop array, businesses can generate their own electricity and significantly reduce their dependence on the grid while lowering energy costs. Solar power enables businesses to harness clean and renewable energy from sunlight, thereby reducing or even eliminating electricity bills. The initial investment required for installing the system can often be recouped within a few years through these cost savings, leading to increased profitability and improved financial stability.

In this case study, Julian Grant, General Manager at Chauvin Arnoux UK, explains how the data from a three-phase PEL provides crucial insights into energy consumption, peak demand times, usage patterns and opportunities to improve energy efficiency while considering installation of solar PV arrays and battery storage.

Integrating a battery storage system with the commercial solar PV array offers businesses greater energy independence and enhanced reliability. Excess solar energy generated during the day can be stored in batteries for use during periods of low solar generation or at night. This stored energy ensures a continuous power supply, reducing reliance on the grid

and protecting against power outages. By having a reliable and self-sustaining energy source, businesses can maintain critical operations, improving overall productivity and customer satisfaction.

Apart from reduced energy bills and reliance on the grid, one other significant advantage of commercial solar PV rooftop arrays is their positive environmental impact. Solar energy is a clean and renewable energy source that produces no greenhouse gas emissions during operation. By transitioning to solar power, businesses can contribute to the global effort to combat climate change, reduce air pollution, and conserve natural resources. Embracing sustainable practices and reducing their carbon footprint enhances the company’s environmental reputation, attracting eco-conscious customers and stakeholders who value businesses that prioritise environmental responsibility.

Commercial solar PV rooftop arrays offer businesses scalability and flexibility to adapt to changing energy needs. With available roof space, companies can easily expand their solar capacity by adding more panels. This allows them to generate additional electricity to meet growing demands. The modular nature of solar systems enables businesses to incrementally increase their capacity over time, aligning with their future growth plans and energy requirements. The flexibility provided by commercial solar PV systems ensures long-term suitability and the ability to scale up as needed.

Thinking About Solar PV? Here’s how you can get started!

Before embarking on a solar PV project, businesses must first gain a comprehensive understanding of their electricity usage patterns by measuring consumption throughout the day and night, assessing variations on a daily, weekly, and monthly basis, and identifying seasonal fluctuations due to factors such as lighting, heating and air- conditioning.

This is best achieved using a portable power and energy logger from Chauvin Arnoux, a powerful instrument that measures and records key parameters such as voltage, current, power, and energy usage. The data from it provides key insights into actual energy usage patterns like identification of peak demand periods, usage trends, inefficiencies, and opportunities to improve energy efficiency.

The energy consumption data collected by the three-phase PEL also plays a crucial role in specifying the sizing of a commercial solar PV array. It enables businesses to estimate the required capacity of the solar panels to generate sufficient electricity to meet their energy demands. By considering factors such as the available roof space and orientation, solar irradiation levels, and energy usage patterns, the data procured from a Chauvin Arnoux power and energy logger ensured that the solar PV system is appropriately sized for maximum energy generation and cost savings.

Incorporating a battery storage system into a commercial solar PV array further enhanced energy independence and reliability. In this scenario, the three-phase PEL helped determine the required capacity of the battery storage system by logging energy usage data during non-sunlight hours. This data provides insights into the amount of stored energy needed to meet the premises’ energy demands during periods of low solar generation or high consumption.

To conclude, investing in a commercial solar PV rooftop array and battery storage system can offer businesses a wide array of benefits. The significant cost savings achieved through reduced electricity bills, enhanced energy independence, and reliability, make solar power an attractive solution.

Moreover, embracing solar energy contributes to environmental sustainability by reducing carbon footprints and supporting the use of clean, renewable energy sources. This way, businesses not only boost their profits but also come across as sustainability leaders, further drawing in eco-friendly customers and partners who appreciate a commitment to a greener future.

Heat networks: change is coming – and overdue

Anthony Coates Smith, Managing Director of Insite Energy

The rapid rise in the number of heat network installations in the UK both contributes to and masks serious problems. According to the Heat Trust, the majority are only 35-45% efficient, when this should be closer to 65-70%.

As well as jeopardising the nation’s net zero targets, this concerning situation is putting the entire sector in a perilous position.

Lagging behind

One key issue is that the pace of market growth, stimulated by government policy, is outstripping the country’s capacity to provide experts to design, operate and maintain these highly complex systems. Like a luxury car, a heat network needs skilful and consistent servicing to optimise its performance and ensure its reliability and longevity.

Heat network technology has evolved enormously in recent years. It’s now much greener and more efficient, with far more emphasis on digitalisation and data. Used effectively, modern data-driven tools can generate vast improvements in efficiency, sustainability and cost-effectiveness.

However, smart technologies are still vastly underused by UK heat network operators, which almost certainly helps to explain why many systems perform so poorly here. It’s very different to other British industries such as finance, retail and manufacturing, where digitalisation has transformed businesses in recent years. It also contrasts with other European countries with more evolved centralised-heating sectors.

Wayfinders

As heat network specialists, we should show leadership in applying proven intelligent data-centric approaches to enhance efficiency, improve reliability, reduce costs and lower carbon emissions. We can also help heat network operators use technology to change consumer behaviours, boost engagement and improve customer experience.

But how does that look in practice? Let me share some notable examples.

One major UK sector innovation has been KURVE, the first web-app specifically for heat network residents on pay-as-you-go billing, launched in 2019. It lets users monitor and manage their energy consumption and pay for their usage quickly and conveniently anywhere, from any internet device.

By offering a quality of customer experience and functionality that banking customers, for example, have benefitted from for years, KURVE is encouraging a sector-wide shift towards more resident-centric service provision and sustainability. Energy use in KURVE households drops by 24% on average, thanks to easy access to real-time consumption data. Furthermore, analysis of KURVE data is informing and improving industry best practice around sustainability and user experience, benefitting even non-users.

Another important development was the 2023 introduction of motivational tariffs to the UK market. This European practice is a form of variable pricing, rewarding heat network users that look after the heating system in their homes, often positively impacting the energy efficiency of the entire network. It directly tackles the ‘What’s in it for me?’ issue inherent in communal heating systems, whereby customers’ heating bills are affected by their neighbours’ actions as much as their own.

Motivational tariffs have been highly effective in Denmark, where heat networks supply 64% of homes. In the UK, we’ve seen lower bills for 81% of residents and a 600% increase in engagement with necessary activities such as equipment-servicing visits.

Digital simulation

A third example of impactful use of data technology is digital twinning. Creating an accurate virtual replica of a heating system’s hydronic design can greatly help to tackle poor performance. A heat network is a vast ecosystem of interdependent components; any intervention can have unintended consequences system-wide. Digital twinning allows you to try things out virtually without the expense, risk or disruption of real-world alterations.

Real-life examples where twinning has been used include the optimisation of the heat network supplying Kew Gardens’ green houses, and the prevention of a huge, ineffective engineering project at a 190-unit London apartment building. However, the approach has yet to gain real traction in the UK heat network sector.

Smart start

I’m glad to say, though, that many data-driven technologies are now widely used with great results. Smart meters, monitoring systems, and pay-as-you-go billing give residents real-time data and better energy control. Smart systems monitor plant rooms and networks, detecting faults, reducing inefficiencies and adjusting to demand. And cloud-based services are enabling remote diagnostics or even repairs, cutting costs and improving efficiency.

In future, we can expect more use of integrated heat source optimisation, where dynamic monitoring selects the lowest-cost, lowest-carbon option in real time. Big data visualisation will also likely make performance monitoring clearer and more effective. With housing associations and local authorities managing heat networks alongside other priorities, tools that make complex data digestible are invaluable – both for operators and customers.

AI may well be increasingly deployed, too, to support smart information services. However, it will never replace humans with chat bots. The recent energy and cost-of-living crises have highlighted the need for authentic, empathetic customer interactions when it comes to essential services like heating.

Social Housing: The unexpected energy efficiency trailblazer

52210932011_03d875eef2_o — Image courtesy of Kensa

Dr Stuart Gadsden, Commercial Director, Kensa

When it comes to upgrading the UK’s ageing housing stock, social housing might not be the first place people think of when expecting to find bold climate action. But it should be, and it’s where technologies that will decarbonise heating for the whole country are already proving what’s possible.

While much of the private housing market continues to debate the “how” of decarbonising and improving energy efficiency at scale, the social housing sector has quietly got on with it. Confronted with complex, often pre-1980s building types, tight budgets, and the responsibility of supporting some of the country’s most vulnerable residents, housing providers have turned challenges into opportunities, proving that energy efficiency, climate ambition, and delivering warmer homes can go hand in hand.

Today, nearly three-quarters of social housing properties are EPC-rated A to C. That’s not just a measure of success; it’s proof the sector is leading the way in tackling fuel poverty, cutting carbon, and delivering better homes and environments for tenants – with low-carbon heating playing a major part.

Why is social housing leading the way?

This progress hasn’t happened by chance. It’s been driven by a mix of purpose, policy, scale, and a commitment to improving lives. Supported first by the Social Housing Decarbonisation Fund (SHDF) and now through the £1.29 billion Warm Homes Social Housing Fund (WH SHF), the sector has shown how targeted government funding can deliver better, more energy-efficient homes for hundreds, even thousands of people at a time.

Building on the success of previous SHDF waves, the WH SHF supports measures including low-carbon heating, improved insulation, ventilation, and whole-building upgrades. This joined-up, mass-scale approach has underpinned the sector’s high EPC performance and delivered some of the country’s most efficient retrofit homes – often in buildings you wouldn’t think would be possible.

Efficiency that delivers

Upgrading entire buildings in one go not only makes sense but can also have a transformative impact. At Kensa, we’ve seen this first-hand, integrating our networked ground source heat pump model as part of the whole-building decarbonisation challenge. Today, around 30 UK tower blocks are receiving efficient, low-carbon, low-cost warmth from this system, and two stand-out examples show this in practice:

At Sutton Dwellings in Chelsea, Clarion Housing retrofitted 81 Edwardian-era flats across four blocks, installing Kensa’s compact ground source heat pumps alongside other energy efficiency improvements. The challenge: improving a heritage site without compromising its character, in a space-limited, urban environment. The result: warm, efficient homes with modern, low-cost heating and hot water.
In Thurrock, 273 flats across three 1960s tower blocks had outdated night storage heaters replaced with the same networked heat pump system — but at a greater scale. Many residents had faced eye-watering bills, but after the upgrade these dropped by up to 66%. Paired with insulation and ventilation improvements, the project delivered a full-building uplift in performance and gave residents homes they could afford to heat.

These projects show what’s possible and offer a blueprint for other providers. By using scalable solutions that cut carbon, tackle fuel poverty, and meet energy standards, Thurrock Council and Clarion Housing are meeting decarbonisation targets and improving the lives of their tenants.

Lessons for the wider sector

Social housing providers have demonstrated what’s possible, with the right scale, strategy and support. By upgrading whole estates and buildings, they reduce disruption, secure better pricing and make a long-term investment while progressing towards net zero goals.

The private sector, in contrast, often upgrades one home at a time – a slower, more expensive, and harder-to-coordinate approach. To accelerate national progress, we need to apply social housing’s lessons more widely:

Retrofit at scale to reduce cost and disruption
Pair insulation with efficient, low-carbon heating for warmer homes and lower bills

The road ahead

There’s still more to do. Thousands of social homes remain poorly insulated or reliant on inefficient heating. Continued funding, policy certainty and support for innovation will be essential.

The WH SHF is a crucial step. Its potential to upgrade more homes and save huge amounts of carbon a year proves its value. But with no further funding expected before 2028, housing providers will need long-term clarity to plan with confidence and keep up the momentum.

Leading the way and showing what’s possible

Social housing has proven that decarbonising and delivering better homes at scale isn’t just possible – it’s happening now. Through coordinated investment, careful planning and a focus on residents, the sector has become a blueprint for sustainable, affordable housing transformation.

The rest of the market now needs to catch up. With the right support, funding and policies, private landlords and homeowners can follow this lead and create a future where every home is warm, energy efficient, and built for the climate challenge ahead.

Rinnai provides turnkey heat pump DHW solution for leading Northwest call centre

Rinnai has provided a low carbon DHW (domestic hot water) Heat Pump solution, with Seasonal Performance Factors (SPF) Analysis, for a Northwest call center to upgrade its existing system to meet government guidance on carbon reduction. The existing hot water system was 2 x 20kW water heaters, each with 300L of hot water storage, and was working at an efficiency level of just 77%.

Find out more about Rinnai R290 commercial heat pump solutions https://www.rinnai-uk.co.uk/products/commercial-heat-pumps

Gathered hot water usage data suggests a peak hot water usage of approximately 542L and a recovery period of less than 1 hour. Based on this information the Rinnai Technical Design Team were able to examine two options suited to the site.

H2 Hybrid Electric System: 3x 9kW R290 Heat Pumps + 1x 300L Heat Pump Storage + 1x 215L Electric Cylinder with 2x 9kW immersion ports

H3 Heat Pump System: 4x 9kW R290 Heat Pumps + 1x 500L Heat Pump Storage.

Because the site only had single phase power, Rinnai opted for multiple 9kW R290 heat pumps rather than one larger R290 commercial air-source heat pump, and the new Heat Pump-based system will now supply all the hot water to all call center staff using sinks, showers and wash hand basins.

To take advantage of Rinnai design services contact us today https://www.rinnai-uk.co.uk/contact-us/help-me-choose-product

The following data was used to enable the client to make an informed choice. The graphs analysis SPF (seasonal performance factors), Operational expenditure, carbon produced, Capital expenditure and the life cycle costs between the Rinnai H2 Hybrid water heating system and Rinnai’s H3 Heat Pump system. The H2 hybrid system is represented in blue whilst the H3 heat pump system is represented in green.

The SPF graph portrays that when taking the entire system efficiency into account, the H2 Hybrid Electric system has an average SPF of 2.50, while the H3 Heat Pump System has an average SPF of 2.72. The key reason for the drop in efficiency of the H2 system is the inclusion of electric cylinders, as opposed to generating all heated water via higher efficiency heat pumps.

The operating expenditure graph shows the H2 hybrid system always has a higher OPEX than the H3 heat pump system across a 10-year period. The H2 system will cost approximately £52,705, while the H3 system will cost around £10,000 less at £42,405, considering a 19.5% decrease in operating costs. The H2 hybrid system requires more grid sourced electricity to be purchased because the efficiency of the electric immersion cylinder is less than the R290 Heat Pump.

When comparing the carbon produced across a 10-year period the H2 system will emit 20,584kg of CO2 whilst the H3 system will emit just 16,562kg of CO2. This demonstrates a 24.3% decrease in carbon production.

CAPEX costs associated with the H2 hybrid electric system will cost £23,245, the H3 heat pump system will cost £26,754, a 13% increase. The reason for the increase is that heat pumps can cost more than electric immersion cylinders. This gives the customer an option of reducing initial expenditure if budget constraints exist.

When combining the CAPEX and OPEX data, lifecycle costs over a 10-year period can be forecast. This reinforced that the H3 Heat Pump system will cost less over its lifetime compared to the H2 Hybrid Electric System. The H3 Heat Pump system will save the customer £6,791 over a 10-year period and will take just two years to become comparable with the H2 Hybrid Electric option.

Rinnai understands the UK customer requirement for cost effective and robust appliances that consistently deliver clean hot water and heating to domestic and commercial buildings across the UK. Rinnai are committed to offering UK customers low cost and practical solutions that cover all energy options.

Clean energy solutions to power a sustainable future

pexels-kervin-3976320 — Photo by Kervin Edward Lara: Pexels

Alexander Gittens, Utilities & Energy Senior Business Development Manager, Getac

From rising global temperatures to natural disasters, the climate crisis is having a negative impact on human health, ecosystems, and costing businesses, with the World Economic Forum (WEF) predicting that by 2050 climate change is likely to cause $12.5 trillion in economic losses worldwide.

The UK is seeking to build a leadership position on climate issues, and its new Planning and Infrastructure Bill adds to this by fast-tracking clean energy projects for grid connections across the country. However, while this is an important initiative from the government, the impetus is also on energy and utilities companies to modernise and enhance operational efficiencies.

Technology is foundational to these efforts. In a sector that’s dominated by field-work in harsh, remote conditions, rugged technologies, in particular, must be geared towards decarbonisation, e-waste reduction, and the efficiency of energy infrastructure and transportation. The time is now for energy and utilities companies to consider how to layer sustainable decision-making into the hardware they deploy. In today’s world, there is a diverse range renewable energy sources available to harness for a greener tomorrow, each offering unique benefits and challenges.

Types of renewable energy sources

Nearly half (47%) of the European Union’s electricity now comes from solar and other renewables, and solar was still the fastest growing power source last year. Solar panels provide around 15-20% efficiency and integrate with the electrical grid bi-directionally to create electricity and balance intermittent energy and power generation elsewhere.

Wind energy, particularly onshore, benefits from higher atmospheric energy levels, and while it can be more variable, it thrives in open, flat areas such as in Denmark, where wind energy is one of the most widely used renewable energy sources. In contrast, offshore wind power is more consistent due to the compound effect of having fewer obstructions than onshore and experiencing a more significant temperature gradient between land and the ocean.

Hydropower takes advantage of hydroelectric energy from the large percentage of water on Earth, harnessing the inherent kinetic energy of water to spin a turbine to generate electricity through a hydroelectric system. With our energy grid increasingly reliant on these sustainable resources, it’s vital to coordinate these various streams to maximise output, stability, and resiliency while keeping costs and environmental impact low. Smarts grids should be thought of as a connective tissue that absorbs the inconsistency of renewable energy and always delivers consistent, reliable output energy.

Tackling the barriers to clean energy rollout

Grid infrastructure quickly becomes a limitation in realising the benefits of renewable resources. Despite significant disagreement on the scale, method, and mechanisms to deliver renewable energy to reduce emissions from greenhouse gases, governments are implementing transformational regulations. For instance, the EU’s Trans-European Networks for Energy (TEN-E) policy, which facilitates investments in cross-border energy infrastructure. But despite these major initiatives, standardisation and permitting processes are barriers to integrating renewable energy into the grid.

Source power intermittency is one of the biggest challenges to clean energy. The sun doesn’t always shine, and the wind doesn’t always blow enough to produce electricity, leading to energy production peaks and troughs. As a result, maintaining resilience and generating electricity through energy storage when the energy is available is the next hurdle to clear. In addition, the cost of renewable energy technologies continues to decline, further elevating demand for energy storage.

Raising public awareness can help drive governments to act, and non-government organisations and activist groups are forming to increase the urgency of shifting to clean energy. Finally, creating public-private partnerships brings innovation and current hurdles directly to the public, raising awareness.

The UK has committed to achieve net-zero carbon emissions by 2050. To reach this ambitious target, society’s prioritisation of clean energy implementation is non-negotiable. Both public perception and universal regulatory alignment will support the bold transition.

Rugged devices with advanced connectivity are key to a greener future

Rugged, durable devices are a primary enabler for implementing green energy globally, especially in field services. They play a fundamental role in future-proofing the UK’s clean energy strategy, and while the UK government has committed to prioritising dozens of ready-to-go projects for on and offshore wind, solar power, electricity grids, hydrogen, carbon capture and nuclear power, this commitment alone will not create this drastic shift.

Rugged solutions transform operations, moving from a pen-and-paper approach to a fully digital one, increasing productivity in field service businesses. A key part of this transformation is the shift away from legacy systems towards more open and flexible platforms like Android, which offer familiar, user-friendly interfaces that streamline fieldwork. Energy and utilities companies must upgrade outdated technology and invest in devices that enable workforce automation and AI-based applications, like predictive maintenance.

Rugged computing solutions are designed for longevity, efficiency, and operational resilience, ultimately reducing the need for frequent replacements, while minimising e-waste and supply chain consumption. By supporting next-generation connectivity technologies, such as private 5G and Wi-Fi 6E, the devices deliver seamless operations, which in turn reduces the carbon footprint associated.

‘How’ is more insightful than ‘how much’

Metering electricity and water in student accommodation offers numerous benefits, for property owners and residents alike. The most obvious being the potential to charge directly for individuals use. Enacting behavioural change to reduce overall consumption is also made possible when data is analysed and presented to occupants. This helps to educate a generation to manage their relationship with resources, preparing them for future independent living.

A building energy management system that is present in every room can engage with100% of residents, unlike apps, where the collection of data is dependent on the compliance of occupants.

Creating awareness of the resources consumed encourages responsibility and offers advantages, ranging from cost-saving to promoting a consciousness of utility value.

In many student properties, utilities are included within the rent, but this can lead to inefficient use. If something is considered free there is no incentive to acknowledge its cost! When students don’t pay directly for their electricity and water, they may be less mindful of their usage.

The shift towards more sustainable practices contributes to significant reductions in overall consumption, which is important in the context of rising environmental concerns. Over time, this hopefully leads to an eco-conscious society that takes energy and water conservation seriously in its daily life.

Combining metering with a communication strategy is being used to encourage behavioural change. Informing occupants of their peer’s average consumption and making them aware of their own leads to lights being turned off, less time spent in the shower, or dressing more appropriately for the time of year. When enlightened, there is a greater tendency to adopt habits that minimise unnecessary consumption. This translates to less water and electricity being wasted, benefiting the environment by reducing the demand for energy generation and water treatment processes.

For property owners, metering utilities helps to manage operational costs. Operators no longer rely on estimates, or risk covering the cost of excessive consumption. Data is collated based on actual usage, increasing precision in predicting demand, therefore, greater accuracy during procurement.

Prefect Irus has recently added three features that uniquely make all the above possible.

Modbus connected energy and water meters. Quantity of consumption data feeds back to the Irus Portal on a block, floor, flat or room basis.
The Irus Optimiser software tool returns insights from automatically analysed data. High consumers are identified, Heating Profile allocation is highlighted, and Occupancy levels presented. It even brings to attention rooms suspected of using supplementary heaters. Recommendations are given on how to act to optimise building services performance.
The new ControlSensor, situated in every bedroom, kitchen, and communal area, features direct-to-room communication so that individual occupants are made aware of their use and advised on how to become more resource-efficient.

Irus provides a twin energy conservation approach. Metering – helps identify problems or over-consumption, while control – physically switches heat sources off when energy isn’t required. Operators have complete visibility of utility use and can act on issues accordingly.

Understanding ‘how’ energy is being used is much more insightful in solving efficiency conundrums, than simply knowing ‘how much’.

Utilising the same infrastructure for control and metering is cost-effective in terms of capital investment and installation, providing a one-stop easy to use platform for energy management.

For environmentally conscious students who prioritise sustainability, metered utilities make accommodation more attractive. Many are fully aware of climate change and environmental impact and would prefer to rent a space where knowledge helps them manage their own consumption. Properties that actively encourage energy efficiency and responsible consumption are likely to attract tenants who share these values.
