Reneo Group (Reneo), a company specializing in the decarbonization of residential real estate, is bringing on board an experienced investment and asset management expert, Lambros Reppas. As Managing Director, he will lead the Institutional Business Line and further develop Reneo Asset Management GmbH, the investment and asset management arm of Reneo Group, as its Managing Director. His overall responsibilities will include not only investment and financing activities but also the establishment of asset and portfolio management for the business line.

“With Lambros Reppas, we are gaining an outstanding expert who perfectly complements our mission to drive the decarbonization and value enhancement of residential real estate. His extensive experience in structuring real estate portfolios and his international expertise will significantly advance our institutional business and help expand our leading market position,” says Alexander Graubner-Müller, Founder and Co-CEO of Reneo.

Lambros Reppas has extensive experience in the international real estate and investment banking sectors. Most recently, he built up Silvertip Capital Germany as Managing Director, overseeing residential portfolios worth approximately €1 billion for international investors and private equity funds. Previously, as Managing Director at Corestate Capital, he shaped the development of the Micro Living & Residential segment and was responsible for pan-European transactions worth billions. His career also includes roles at AXA Investment Managers, INOVALIS Group, SVP Global, and HOIST Finance.

A Pioneer in residential real estate decarbonization

With this new appointment, Reneo is consistently continuing its growth strategy. As a technology and asset management platform, the company focuses on the sustainable transformation of the residential real estate market. Supported by €600 million in funding from investors such as Peakside Capital, Eurazeo, and Goldman Sachs, Reneo has already transacted over €500 million in existing residential properties in recent years. In 2024 alone, more than €200 million was invested, primarily in Hamburg and Berlin. In the coming years, further significant investments are planned for implementing develop-to-green strategies in Germany’s top seven cities.

The core of Reneo’s corporate strategy is the holistic decarbonization of residential buildings, particularly so-called stranded assets. Using its proprietary end-to-end technology platform, RCS (Reneo Core System), Reneo analyzes the energy performance of properties and optimizes investment and renovation strategies. This approach enables energy consumption reductions of up to 60% while unlocking significant value appreciation potential for investors.

“The transformation of the real estate market requires innovative solutions that align environmental and economic goals,” says Lambros Reppas. “I look forward to developing sustainable investment strategies with the Reneo team and our institutional partners and making a decisive contribution to the climate neutrality of Germany’s building stock.”

With a strong focus on digital process optimization, sustainable renovations, and innovative financing models, Reneo positions itself as a leading partner for investors who want to actively shape the sustainability-driven transformation of the residential real estate sector.
