aedifion Secures €17M to Help Building Owners Slash Energy Bills and Carbon Emissions

Cologne-based proptech company aedifion has raised €17 million in an oversubscribed Series B funding round. The round was led by European growth investor Eurazeo, with strong participation from existing backers, including Drees & Sommer, which significantly increased its commitment. New and returning investors also included World Fund, BitStone Capital, Family Office Hopp, Phoenix Contact Innovation Ventures, MOMENI Ventures, Bauwens Capital, and LARTIS.

Alice Besomi, Managing Director, and Raphael Cattan, Investment Director at Eurazeo, mention, “With this investment, via our Eurazeo Smart City Fund II, we are supporting aedifion’s mission to make buildings smarter and more energy-efficient. Their scalable platform is the easiest solution for asset managers to drive energy efficiency and emissions reduction across real estate portfolios. We’re excited to help scale their impact across Europe.”

Founded in 2017 as a spinoff from RWTH Aachen University, aedifion is on a mission to decarbonise buildings across Europe. Its AI-powered cloud platform enables real estate operators to reduce energy consumption, lower costs, and significantly decrease CO₂ emissions. The system accomplishes this by monitoring and managing heating, ventilation, and air conditioning (HVAC) areas, which typically account for a significant portion of a building’s carbon footprint.

The problem is no small one. Buildings are responsible for roughly 36 per cent of energy-related greenhouse gas emissions in Europe. Aedifion’s platform has already demonstrated that it can reduce those emissions by as much as 40 per cent in some properties.

Today, aedifion oversees the operations of nearly 500 buildings across Europe, the UK, and the US, representing more than 5.8 million square meters of real estate. The platform operates by collecting real-time data, identifying performance issues, providing optimisation advice, and automatically adjusting systems based on factors such as user behaviour and weather forecasts.

The company employs over 100 people and is dedicated to developing solutions that are both open and interoperable. Its platform includes an API designed to integrate with other proptech tools, and it meets Germany’s Building Energy Act standards, certified by TÜV Rheinland.

With this latest round of funding, aedifion will continue expanding its reach throughout Europe while investing heavily in its technology. This includes ramping up work on intelligent energy management tools, such as AI-supported demand-side load optimisation, to help buildings operate more efficiently during both peak and off-peak hours.

Perhaps most intriguing is the development of a generative AI-powered virtual assistant for buildings. This tool will be able to process voice and text instructions, drawing on both proprietary building data and the capabilities of large language models to provide fast, actionable answers.

Dr.-Ing. Johannes Fütterer, CEO of aedifion, says, “With Eurazeo, we have gained an experienced growth investor that shares our vision of sustainable, data-driven real estate. Smart buildings and artificial intelligence will play a crucial role in the energy transition.”

“This new funding will enable us to further scale our solution and establish aedifion as the leading platform for the digital operational optimisation of technical building systems throughout Europe. Our platform has been proven to reduce energy usage by up to 40 per cent – we can thus make a decisive contribution to the decarbonisation of real estate and the preservation of its long-term value.”
