Brunata, one of Denmark’s leading cleantech companies specialising in energy metering and data-driven insights, has just released its latest financial results. The company reports a revenue of DKK 366.7 million, marking a nearly 5 percent increase compared to the previous year. Operating profit rose by 15 percent to DKK 84.5 million – the best financial result in Brunata’s 106-year history.

“This result is highly satisfactory and exceeds our expectations for the year. We have consolidated our core business as Denmark’s preferred provider of consumption accounting and evolved from offering standalone metering solutions to delivering flexible, subscription-based services. These create great value for our customers through increased transparency, predictable costs, and better digital tools for energy management,” says CEO Jesper Holm Kristoffersen.

“One of the biggest milestones of the past year was our breakthrough in the utility water sector. We are now the only player in the industry offering an integrated solution that combines modernisation, digitalisation, and operations. This enables both small and large utility companies to future-proof their infrastructure with fewer resources and greater operational reliability.”

Technology-driven performance

The financial year also saw significant technological advancements within Brunata’s organisation. The company has invested in automation, scalable digital infrastructure, and new solutions for both existing and new customer segments, including utility providers. Key initiatives have also focused on enhanced data security and smarter building operations.

“In 2024, we accelerated our digital development, including automation of our consumption accounting processes and closer integration between our CRM, ERP, and proprietary platforms. This has made us faster, more accurate, and scalable. We’ve also grown our customer base, and our solutions are now better equipped to handle large volumes of data and complex customer needs. This setup strengthens our competitiveness in a market with increasing demands for flexibility and data security,” says Jesper Holm Kristoffersen.

A new strategy for future growth

Brunata is now entering a new strategic period through 2028, aiming to increase revenue by 5–10 percent and profits by up to 5 percent annually. The strategy focuses on expanding into new customer segments, especially utility companies – a sector where Brunata has already signed agreements with around 25 water utilities in Denmark.

“We are undergoing a transformation that requires greater alignment and cross-organisational collaboration with a shared understanding of our digital strengths. With our existing technology and platforms, we can deliver high-value solutions to entirely new segments. The foundation is in place, and now it’s about scaling. Our online platform and data network are not just tools – they are the centrepiece of our future business,” Kristian Voldby Olsen CEO for Brunata International explains.

“Competition in our industry is becoming increasingly fierce. It’s a tough market, but that doesn’t change our ambition for continued growth. In the coming years, we expect many of the trends we already see to grow even more significant. For example, we’re seeing increasing interest in consumption accounting for resources beyond heating – especially cold water and other energy types. These developments open up new opportunities that we intend to pursue to further strengthen our growth.”

Brunata is participating in an ambitious research project aimed at exploring how artificial intelligence and wireless energy meters can help housing associations and landlords utilise heat more intelligently – and more sustainably.

The project, named HeatCheck, is led by researchers from DTU Construct and is carried out in close collaboration with utility companies, housing associations, and companies such as Brunata, which specialises in consumption accounting.

The project makes use of the vast amounts of data collected daily by wireless heat cost allocators already installed – including those installed by Brunata – in thousands of homes across the country.

“The combination of data from heat allocators and newly developed digital tools gives building owners an unprecedented opportunity to operate their heating systems efficiently,” says HeatCheck project manager, Associate Professor at DTU, Christian Anker Hvid.

At the same time, there is a strong need to rethink how we heat our homes. As district heating providers gradually lower temperatures in the coming years, it will become necessary to use energy more efficiently.

“In return, the benefits are significant for both residents, property owners, and the climate,” the researcher emphasises. “The savings potential amounts to billions of euros across the EU.”

Better and greener use of heat

Kees van der Veer, VP of IT & Software Development at Brunata, welcomes the collaboration:

“We have previously participated in research projects with DTU and gained valuable insights. A recently completed study clearly demonstrated that there is great potential to utilise district heating in residential buildings far more efficiently.”

“With HeatCheck, we are now taking the next step. We are contributing to the development of concrete models and tools that can control and optimise heat usage much more precisely – for the benefit of both residents and the climate.”

Brunata already uses data in its solutions today – from consumption accounting and EED notifications to IoT-based services that help housing associations optimise their energy use.

With the results from HeatCheck, the hope is to further accelerate energy optimisation. Using advanced AI models, the vast amounts of data will be analysed and converted into actionable insights.

“Hopefully, this means that heat can be controlled more precisely, faults can be detected earlier, and energy can be used far more efficiently. The result will be less waste, lower costs, and improved comfort – benefitting both residents and the climate.”

A broad collaboration with a shared goal

“HeatCheck is a very good example of how far we can go when we work together across disciplines and industries,” says Jesper Holm Kristoffersen, CEO at Brunata. “If we are to succeed with the green transition – and we must – there is a real need to think outside the box and make full use of each other’s knowledge, experience, and competencies.”

Behind HeatCheck stands a strong consortium consisting of DTU, district heating companies such as HOFOR, Aalborg Forsyning and Horsens Fjernvarme, housing associations such as KAB, Boligselskabet Sjælland and Bolig Horsens – as well as the companies Brunata, Ista and Techem.

“It is powerful that we can jointly develop a digital toolbox designed to make it easier for building owners to gain an overview, identify issues, and optimise their heating systems.”

“We are in the midst of a green technological breakthrough. When we use data the right way, we can make district heating intelligent – and buildings more sustainable,” says the HeatCheck project team.

HeatCheck was launched in 2023 and is already well underway. The project’s progress can be followed on its website: heatcheck.dtu.dk

A new ten-year strategic partnership between Brunata and Lyse Energiservice AS aims to advance the digitalisation of energy consumption in Norway – and make it easier for housing companies, property owners and residents to contribute to a more sustainable future.

Brunata, headquartered in Herlev, Denmark, has for several years supplied metering technology, consumption data, and consumption accounting to Lyse Energiservice – one of Norway’s largest providers of individual metering and billing services for energy and water in housing associations and commercial buildings. With this new agreement, Brunata will expand its deliveries and will henceforth assume responsibility for a greater share of the value chain – from planning and logistics to installation, resident communication, and ongoing operation of meters, networks, and data management.

The agreement spans ten years and signifies a long-term commitment to joint development and innovation. It is also a strong expression of Lyse Energiservice’s confidence in Brunata’s solutions and technical capabilities.

“We look forward to further developing our partnership with Brunata. The green transition requires accurate energy data and a robust infrastructure. In this regard, Brunata has demonstrated expertise, and we are pleased to have a partner who shares our ambitions – particularly at a time when energy prices are rising and both residents and property owners are demanding fair and transparent distribution models based on actual individual consumption,” says Kristian Helland, Chief Executive Officer at Lyse Energiservice AS.

Brunata will have a permanent presence at Lyse’s main offices in Stavanger, Oslo, and Bergen. This will enable closer collaboration and provide Lyse and its customers with convenient and prompt access to support and expertise.

From metering to insight and action

Brunata is one of Europe’s leading cleantech companies specialising in energy metering and data-driven insight. The company uses IoT solutions and intelligent data analysis to create transparency regarding consumption patterns, behaviours, and opportunities for energy savings – down to individual apartment level. This provides property owners and residents with concrete knowledge about where and when energy is used, and how it can be used more efficiently.

“We regard data as an asset. With our technology, we make energy consumption transparent and understandable, making it possible to act wisely. In Norway, we are witnessing a clear shift: energy prices are more volatile than before, and there is growing attention on how buildings can use resources more sustainably. Accurate metering and access to data play a decisive role in this,” says Eirik Øhlschlägel, Country Manager at Brunata Norway. He elaborates:

“With a local presence in Stavanger, Oslo, and Bergen, we can offer solutions tailored to specific needs and provide close support to our customers in their daily operations – making everyday life easier. This also helps reduce energy waste, lower costs, and support climate goals.”

A clear path towards sustainability

This new agreement comes at a time of fluctuating energy prices and increasing demands for sustainability. For both Lyse and Brunata, there is a shared ambition to deliver solutions that are both reliable and future-proof.

“In the Norwegian market, we see a clear shift towards more data-driven property management. Energy prices are unstable, and we can contribute with tangible solutions that enable smarter use of resources – both financially and environmentally. The collaboration with Lyse demonstrates how our technologies and experience can bring local value while supporting a broader movement towards a more sustainable housing sector,” says Jesper Holm Kristoffersen, Chief Executive Officer at Brunata A/S.

Last week, Kristian travelled to Brussels to take part in a High-Level Stakeholder Dialogue on Energy Efficiency hosted by EU Energy Commissioner Dan Jørgensen. As a board member of EVVE — the European Association for the Consumption-based Billing of Energy Costs — Kristian was invited to help represent the submetering industry’s voice in support of Europe’s climate goals.

The meeting gathered key voices from across Europe — industry leaders, associations, NGOs, and policymakers — to explore how we can accelerate the green transition and meet the EU’s ambitious climate targets.

We caught up with Kristian after the meeting to hear his reflections and his perspective on the vital role the submetering business can play in creating smarter, more efficient buildings across the continent.

A room full of ambition—and action

“It was inspiring to be part of a conversation that focused not just on policy, but on what is actually working,” Kristian begins. “We were not there to talk theory — we were there to explore real-world solutions.”

“Everyone agrees that we need to reduce emissions and improve energy security. But energy efficiency — although central to the solution — is often overlooked when we talk about the green transition. Fortunately, that is starting to change. A new binding EU-level target has been set to improve energy efficiency by 11.7% by 2030. And buildings will play a key role in achieving it.”

Are buildings our biggest opportunity for energy savings?

The built environment is responsible for around 40% of energy use in the EU and over a third of its carbon emissions. That makes them a critical focus in the EU’s plan to reduce greenhouse gas emissions by 55% by 2030 — known as the Fit for 55 package — and long-term Green Deal ambitions.

“The truth is that a huge share of our energy is used for heating—and a lot of that is wasted,” Kristian says. “If we can make that energy use visible, so it can be reduced. And this is where out industry and companies like Brunata can make a huge impact.”

Through submetering and consumption-based billing, residents, property managers, and building owners gain a clear view of their energy use — and the ability to act on it. Research shows this transparency leads to energy savings of 10–15% on average, with even more when regular feedback is introduced.

“It is a classic case of low-hanging fruit,” Kristian explains. “We already have the technology, we already know it works. Our industry is already inside buildings and apartments all over Europe — with meters and networks that are up and running. Now it is about implementation and scale.”

Speaking with MEP Niels Fuglsang

At the meeting at the Commission, Kristian had the opportunity to share his views with MEP Niels Fuglsang of the Danish Social Democrats. He leads negotiations on the EU’s Energy Efficiency Directive.

“It was truly great to have the attention of a leading voice in the EU,” says Kristian. “Fuglsang seemed genuinely interested in the potential of what the submetering industry can offer. I explained that we already have the technology and are present in homes and buildings across Europe.”

“We have already come a long way, but the real breakthrough happens when we combine consumption data with intelligent heat control. That is when we can take a big leap in efficiency — cutting energy use in ways that are both measurable and meaningful.”

“You cannot optimise what you cannot see. Measurement is the first step to change,” Kristian adds.

Looking ahead

The EU has committed to cutting greenhouse gas emissions by 55% by 2030 and becoming climate neutral by 2050. The ambition to improve energy efficiency by 11.7%. is a target that Kristian believes is entirely achievable with the right tools and partnerships.

“Our industry is ready,” he says. “We are already present in homes and buildings across the continent. We have the networks, the devices, the data. What we need now is support for full-scale rollout and recognition of the value we bring.”

“We are in a hurry to become independent of fossil fuels and cut carbon emissions. But what I saw in Brussels gave me hope. There seems to be real momentum behind action — and it is clear the submetering industry has a crucial role to play.”

Most people are familiar with this scenario: the radiator is turned up fully during winter, yet some residents complain about being cold while others are too hot. Heat distribution is uneven, leading to unnecessarily high operating temperatures, heating bills, and energy waste.

However, according to a new research project from DTU, there is a far smarter way to utilise remote heating that benefits both the environment and finances. The project shows that heating systems, without requiring major investments, can be significantly optimised by leveraging the potential of IoT-based heat meters.

“Many people think that large, expensive renovations are needed to achieve low temperatures, but our study shows that significant improvements can be achieved simply by adjusting how heat is distributed,” explains Michele Tunzi, associate professor at DTU. He led the study, conducted in collaboration with Viborg Varme, BoligViborg, and Brunata, which provided wireless heat meters and IoT-based networks for data collection.

“Our research demonstrates that both the supply and return temperatures can be reduced significantly by optimising heat distribution. This results in major savings on heating bills and environmental impact. And it does not necessarily require investments in insulation or extensive renovations. We simply use the data collected from the building’s wireless consumption meters to manage the heat more intelligently,” Tunzi elaborates.

Evenly distributed heat is more efficient

The researchers conducted their experiments in several multi-apartment buildings in Viborg, where Brunata’s IoT-based heat meters were used to analyse how heat could be most effectively distributed within the properties.

The results showed that the supply temperature in the radiators could be reduced below 55 degrees Celsius for the majority of the heating season without affecting residents’ comfort.

By intelligently managing the building’s overall heating system, heat can be distributed more evenly, eliminating large temperature fluctuations from flat to flat.

Tripling the annual heating discount

“We conducted a study in standard apartment complexes in Viborg, Denmark. For an annual heating consumption of 314 MWh distributed across 30 flats, it was estimated that by achieving an average return temperature of 37°C, the tenants could receive an annual discount of approximately DKK 7,000 on their total heating bill,” explains Tunzi.

“But this discount could increase to approximately DKK 24,000 if the average annual return temperature is lowered to 32°C,” Tunzi continues. “This corresponds to a discount of DKK 800 per flat. Conversely, an average return temperature of 45°C would result in a penalty of DKK 14,400 for the tenants,” based on the current bonus and penalty included in Viborg Varme’s heating price structure.

Turning off radiators can be expensive

One surprising conclusion from the study is that the habit of turning off individual radiators during the winter months can prove costly.

“Turning off one radiator in one room forces the other radiators in that flat or in neighbouring flats to compensate for the missing heat to maintain the expected comfort. This results in inefficient and unfair heat distribution among flats,” says Tunzi.

This also means that the return temperature – sent back to the district heating networks – becomes too high, increasing heating costs and environmental impact.
