An important milestone has been reached this year, now that the solution from Danfoss partner, Leanheat, has been installed in 100,000 apartments worldwide. The smart heating solution helps to reduce 10–20 percent of a building’s total energy cost. But the potential is much bigger.


Digitalization is transforming the way we consume and optimize energy usage in buildings. Already today, artificial Intelligence (AI), self-learning systems and data-in-the-cloud play a key part in the smart building services that Danfoss partner, Leanheat, delivers to district heating utility companies and building owners.


And this year marks an important milestone for Leanheat, which now provides comfortable heating to residents in 100,000 apartments owned by housing associations.


The Leanheat solution uses artificial intelligence to optimally control and monitor centrally heated buildings. Data from the central building control room is combined with data collected from Internet of Things (IoT) sensors (wireless) located in individual apartments in the building. By using AI to process the collated data, the central heating can be controlled in an optimal manner depending on weather, ventilation and the inhabitants’ living patterns.


The rental housing provider, Espoon Asunnot, in the city of Espoo, Finland, has had the solution installed in all of their 15,000 apartments. The benefits of signing up for Leanheat services have been extensive.


“Our aim was to rationalize heat consumption and improve indoor air quality in the apartments. And on this we have, for sure, succeeded. During the three years we have worked with Leanheat, we have managed to cut our energy consumption and peak power demand significantly, more than 6 percent and 17 percent respectively,” says Jaakko Kammonen, CEO of Espoon Asunnot. The housing company is Leanheat’s second biggest customer with apartments at 300 different sites. With the solution from Leanheat, the entire Espoon Asunnot property portfolio saves the energy of approximately 1,000 one-family-homes annually, equivalent to saving about 2,500 tonnes of CO2.

Potential for more smart buildings


And the potential for making more buildings smarter and saving more energy is even greater. Today, 30 percent of the energy consumption in Europe is used to heat and cool buildings. This must be addressed if the world’s sustainable development goals (SDGs) and the Paris Agreement are to be met. Here, digitalization plays a vital role, says CEO of Leanheat, Jukka Aho:


“In Europe today, most technologies to reduce energy consumption is related to new buildings. However, the base of new buildings is only two percent which means it will take us 50 years to renew all buildings. Our solution is scalable and can be fitted into existing buildings. And this is where we find the big potential. We need to make more buildings smart if we want to cut energy consumption in the European building stock.”


Leanheat’s solution has already been installed in buildings in Finland, Denmark, Sweden, Germany, Poland and Norway. New pilots with district heating companies in China are showing great potential. Currently they operate with six district heating companies and have nine commercial pilot projects in the pipeline.


The start-up development of the intelligent monitoring solution began in 2011, and the first pilots were set up. In 2016, the company Leanheat Oy was established and recognized as a first-mover within digital HVAC efficiency. In the same year, Danfoss entered into a partnership with Leanheat and added this new digital element to its core portfolio. Today, Danfoss holds 46 percent of company shares in Leanheat.
