About us
Use energy with care
From intelligent metering and utility billing services to advanced energy management systems and IoT solutions, Brunata makes consumption visible and transforms data into valuable insights that support better decision-making.
Embrace the future
Energy and water are a natural part of everyday life, but it can be difficult to see where and how these resources are being used. At Brunata, we make consumption visible through intelligent metering, IoT technology, and data-driven solutions.
We are a cleantech company specialising in intelligent metering and data-driven solutions for residential and commercial properties, public buildings, water utilities, and more. By combining data, intelligent technology, and IoT solutions, we make consumption visible and provide valuable insights that support better decision-making.
Our mission
We deliver intelligent solutions that turn data into insight. Through meters, sensors, and digital solutions, we collect and connect data on water, heating, and electricity consumption, as well as indoor climate conditions.
Data makes it easier to understand what is happening across buildings and utility networks, identify irregularities, and take action when needed.
An international corporation with Danish origins
You can find Brunata’s products, services, and offices throughout Europe, extending from the North Cape in Norway to the southernmost tip of Italy.
Our headquarters are situated in Herlev, Copenhagen, where we collaborate closely with our subsidiaries and partners across more than 17 European countries.
With a history spanning over 100 years, our roots are firmly Danish. However, similar to many significant Danish technology companies, our outlook and operations are global. Today, we are part of the German-owned Brunata-Minol-Zenner group, which employs over 4,200 individuals worldwide.
Brunata is a leading specialist in consumption accounts, energy measurement, property-based IoT solutions and energy management.
ZENNER produces measurement technology for global markets. Primary target groups include utilities, energy suppliers and municipalities.
Minol is a leading global service provider to the property industry, specializing in consumption accounts and related services.
Brunata’s products, services and offices can be found across most of Europe, spanning from the North Cape in Norway to the southern tip of Italy.
Our solutions and services
To achieve our goal of streamlining and modernising our energy usage, we have structured our company around four key business areas. These encompass everything from small heat cost allocators to advanced energy monitoring systems.
Consumption accounts
Accurate and reliable consumption accounts are at the heart of our business. They offer administrators and consumers a comprehensive overview of the allocation of costs for water, heating and electricity.
Historically, these accounts were delivered on paper; however, today they are electronic and based on remote reading measurements.
Measurement technology
We offer an extensive range of innovative and intelligent consumption meters, including heat cost allocators, water meters, electricity meters, gas meters, indoor climate sensors, smoke detectors and network components among others.
All our devices seamlessly integrate with wireless networks, enabling them to communicate with each other and transmit data to our energy monitoring system, Brunata Online, or other compatible platforms.
Smart Building
Imagine a building that can monitor its own energy consumption, identify the locations and amounts of water usage, sense the indoor climate and detect leakages.
This is Brunata Smart Building, our Internet of Things solution, designed to maintain the health and safety of properties by integrating the building’s sensors and meters into an intelligent network.
From the past to the future
Innovation and technological development have been integral to our ethos from the very beginning. As early as 1917, Danish engineers, such as Constantin Brun, began researching and utilising heat cost allocators based on thermoelectric principles.
In the 1930s, Brun identified the potential to develop heat cost allocators and an accounting method that could accurately and fairly distribute a property’s heating consumption. This led to the creation of the consumption account and the establishment of the engineering firm Constantin Brun A/S.
In 1950 Constantin Brun A/S merged with the Swiss firm ATA, expanding its reach beyond national borders. The new entity was named Brunata, a contraction of the two original names.
Throughout the 1960s, 70s, and 80s, Brunata continuously developed and refined its business, solutions, and services. By the mid-1990s, the first wireless Brunata meters were introduced to the market, enabling remote reading and marking the initial step towards a wireless future.
In 2005, the digitalisation of the consumption account commenced. Brunata now provides consumers and administrators with online visualisation of their consumption data.
In 2018, Brunata was acquired by the family-owned German company Minol, a global leader in energy, measurement technology and data networks. Concurrently, the company became part of the Brunata-Minol-Zenner group.
Today, Brunata is pioneering the development of intelligent meters and IoT solutions, where sensors are connected to online platforms via digital networks.
