Berlin, 08th July 2026. Since the turnaround in interest rates and the parallel surge in demand for renewable energy in the property sector, prices have been diverging. This applies to both residential and non-residential buildings. Properties with a high ESG rating are, on average, seeing rising prices. Conversely, properties with poor ratings tend to lose value.

This is precisely where the Berlin-based energy and refurbishment consultancy Fuchs & Eule comes in. The €10 million funding round is led by GET Fund as the lead investor. Other participants include new investors PI Impact and WaVe-X, as well as existing investors SET Ventures, Picus Capital and Realyze Ventures. The funds will primarily be channelled into expanding the digital business model. For example, this includes AI technologies, the development of intelligent screening tools, data-driven analyses and personalised renovation advice.

The aim is to lay the foundations for transforming property portfolios to make them more energy-efficient. Data-driven in-house analyses and AI-powered solutions are essential to this. This enables refurbishment decisions to be made with the utmost precision and property portfolios to be developed in a way that adds value. The company boasts average savings of 21.6 tonnes CO₂ per building per year.

Mission: Building Transition - Harmonising Economy and Ecology

Drawing on a broad portfolio of services, the company offers bespoke, data-driven services for professional property owners.

The process begins with an AI-supported portfolio screening, which Fuchs & Eule uses to identify buildings with the greatest potential for refurbishment and value enhancement. Building on this, the experts produce detailed building analyses and digital twins, from which concrete and economically viable refurbishment measures are derived. The service is complemented by comprehensive advice and support on grant funding, assisting clients from the selection of suitable programmes right through to the application process.

This enables energy-efficiency measures to be implemented for effective climate and environmental protection. In addition to property owners, yield-oriented investors can benefit from rising portfolio values.

Fuchs & Eule thus addresses a key challenge in the energy transition: every building is different. There is no one-size-fits-all solution for either residential or commercial properties. Specialised expertise therefore becomes a decisive factor for the success of the green retrofitting of properties throughout Germany

High costs and technical complexity are holding back energy efficiency in existing buildings

As of July 2026, building owners face a twofold challenge. High investment costs for modern heating, ventilation and air-conditioning systems, as well as the refurbishment of the building envelope, are coming up against tight budgets. At the same time, the difficult economic climate makes economic efficiency more important than ever.

On the other hand, the implementation of energy-efficiency measures is, in some cases, so complex that a large number of decision-makers are postponing the final steps until the distant future. The losers in this dynamic are both the climate and building owners, due to a lack of action and falling property values.

"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," says Dr Tobias Frese, Co-CEO of Fuchs & Eule.

'Done-for-you' solution appeals to ambitious investors

On the face of it, it was Fuchs & Eule's bespoke service framework that fully convinced the investors.

"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."

Given the clearly defined EU regulations - such as the EU Buildings Directive - Fuchs & Eule is right on trend. Under these regulations, 16 per cent of all non-residential buildings with the poorest energy performance across the EU must be refurbished by 2030. By 2033, this figure rises to the bottom 26 per cent. These tight deadlines cannot be met without sufficient expertise.

"Fuchs & Eule is working on one of the biggest decarbonisation levers in Europe - we are very much looking forward to continuing to support the company so that it can grow in this market and generate impact with its data-driven insights and solutions," said Dr Till Stenzel, Partner at SET Ventures.

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."
