Energy Management: Green Fusion and Viessmann Cooperate

This summer, the startup Green Fusion made waves not only through its cooperation with the Viessmann Group. It is now even considered a market leader in the field of intelligent heating system control. We were curious and spoke with Green Fusion CEO Paul Hock about the technology, the cooperation project, and current trends and developments in the field of energy management.

Paul, how would you describe in an elevator pitch what drives you and what problem you’re solving?

Green Fusion enables energy and CO2 savings of an average of 20 percent through intelligent heating system control. This applies both to conventional heating systems, such as gas boilers, in existing buildings, as well as to innovative energy systems, like heat pumps and photovoltaics, in neighborhoods. This allows heterogeneous housing company portfolios to be easily and continuously monitored and optimized using artificial intelligence.

What sets your energy-saving pilot apart, and how do you differentiate yourselves from comparable providers?

Green Fusion can control almost any (centralized) heating system in multi-family homes, enabling remote access. Through this, we can automatically translate AI-driven analyses into the system and continuously optimize the systems without significant user interaction, making them self-learning over time.

Another key USP of Green Fusion, especially for the future, is the ability to connect the heating system with photovoltaic systems, battery storage, and electric charging stations to increase the energy system’s efficiency and utilize synergies.

You made headlines this summer due to your cooperation with Viessmann. How did the collaboration come about?

We’ve been in contact with the Viessmann team for a long time. I actually reached out to them through their contact form back then.

The main advantage, especially for us, is the ability to get data via their API directly in the cloud, not locally in the basement, and to control the systems remotely. This allows us to eliminate the need for hardware in the future, making us even more scalable. Since we are one of the first companies to do this and see a lot of potential in the collaboration, it was time to officially announce our partnership.

Were there any specific challenges during the initiation and implementation of the project, and how did you overcome them?

Of course, since this is new territory for both of our teams, we had to carefully discuss various aspects, both in contract negotiations and in implementing the API. However, from the start, it was a very constructive process. We quickly realized that Viessmann also sees great potential in our collaboration and was able to support us well.

Why is your cooperation particularly important for the energy transition?

Viessmann is one of the largest players in the energy production sector, both in conventional and renewable areas. Therefore, optimizing systems is inevitable. In the future, this will provide great momentum, especially as it becomes easier to integrate Viessmann heat pumps and save money and effort during implementation.

What is your strategy as a startup or young team to gain the trust of your partners?

We were recently named the market leader by GdW, the largest housing association in Germany. That kind of recognition really gives us a boost. We now have over 80 customers in the housing industry and are no longer seen as “just another” startup. Partnerships with companies like Einhundert Energie, Ampeers Energy, and even Vodafone have also helped.

I also believe that we are considered a reliable and trustworthy partner, and both sides must always benefit from such collaborations.

Paul, what are the most important topics and trends in energy management for you personally right now? And how is your team approaching them?

In addition to decarbonizing existing energy systems in multi-family homes, the development toward heat pumps is a top priority. Once a heat pump is installed, it should communicate with the PV system and benefit from dynamic electricity tariffs. Very soon, there will be the possibility to “connect” all these energy producers and consumers into a virtual power plant — we’re particularly excited about this because it will fully showcase the value of our autopilot!
