Fuchs & Eule has raised 10 million euros to expand its AI-powered platform for building energy renovation. The Berlin-based company helps professional property owners identify, prioritise and implement the retrofit measures that can improve energy performance, reduce emissions and protect asset value.
The funding round is led by GET Fund. New investors PI Impact and WaVe-X also participated, alongside existing investors SET Ventures, Picus Capital and Realyze Ventures.
Fuchs & Eule will use the capital to further expand its digital business model, including AI technologies, intelligent portfolio screening tools, data-driven building analyses and personalised renovation advice. The company’s approach is designed to help property owners move from complex energy-efficiency decisions to clear, investable renovation plans.
Across its projects, Fuchs & Eule achieves average savings of 21.6 tonnes of CO₂ per building per year.
Helping property owners make better retrofit decisions
Buildings are one of Europe’s largest decarbonisation challenges. At the same time, property owners are under growing pressure from higher energy costs, stricter regulation and changing asset valuations.
Since the rise in interest rates and increased demand for renewable energy in the property sector, the market has become more selective. Residential and non-residential buildings with strong ESG performance are generally better positioned, while inefficient buildings face growing risk of value decline.
Fuchs & Eule addresses this challenge with a data-driven, done-for-you retrofit solution for professional property owners. Its platform combines AI-supported portfolio screening, detailed building analysis, digital twins, engineering expertise and subsidy advice.
This allows property owners to understand which buildings should be renovated first, which measures make economic sense and how to turn energy-efficiency plans into practical implementation.
“The biggest hurdle is not the willingness to renovate, but the complexity of the decisions. We make them manageable, with AI-supported analyses, clear recommendations for action and sound advice for the entire property portfolio,” said Dr Tobias Frese, Co-CEO of Fuchs & Eule.
From portfolio screening to implementation
Fuchs & Eule begins by screening property portfolios to identify the buildings with the greatest potential for energy savings, emissions reduction and value improvement.
The company then develops detailed building analyses and digital twins, which are used to define specific retrofit measures. These can include heating, ventilation and air-conditioning upgrades, improvements to the building envelope and other energy-efficiency measures.
Fuchs & Eule also supports clients with grant funding, from identifying suitable subsidy programmes to preparing applications. This is particularly important in a market where high investment costs and limited internal capacity often delay renovation decisions.
By combining software, data and energy expertise, Fuchs & Eule gives property owners a practical route to improve building performance while supporting the wider energy transition.
Why SET Ventures continues to back Fuchs & Eule
For SET Ventures, Fuchs & Eule sits at the intersection of energy efficiency, digital infrastructure and real estate value creation.
Existing buildings are one of the most important decarbonisation levers in Europe, but the market remains held back by fragmented data, technical complexity and generic retrofit advice. Fuchs & Eule’s model addresses this by turning building-specific data into clear recommendations and actionable renovation plans.
“Fuchs & Eule is working on one of the biggest decarbonisation levers in Europe: the existing building stock. By combining granular data, AI-supported analysis and deep building expertise, the team helps property owners make better retrofit decisions at scale. We are very pleased to continue supporting the company as it grows in this market and delivers impact through data-driven insights and solutions,” said Dr Till Stenzel, Partner at SET Ventures.
Regulation is increasing the need for retrofit expertise
European regulation is also accelerating the need for building renovation. Under the EU Buildings Directive, member states must ensure that 16 per cent of the worst-performing non-residential buildings are renovated by 2030. By 2033, this rises to the worst-performing 26 per cent.
Meeting these targets will require more than broad recommendations. Every building is different, which means owners need specific, data-backed guidance on what to renovate, when to act and how to make projects economically viable.
“I have been working on building retrofits since their launch in 2005, and I have been frustrated by the one-size-fits-all recommendations with inconsistent quality,” said Dr Isabelle Canu, Partner at GET Fund. “Fuchs & Eule stands out by translating building physics into bespoke retrofit measures that make sense both energetically and economically. That is why I am excited to back the team.”
Lotte Stoltenborgh, Investment Manager at PI Impact, added: “Fuchs & Eule has built an impressive model that combines highly granular data, strong AI-powered calculations and deep expertise to support better decision-making.”
