Sustainable Investments: Modernized Existing Properties vs. New Construction

Due to the EU Green Deal and the associated regulations, demand for sustainable real estate investments is steadily increasing. In many cases, investors automatically focus on new buildings – assuming they are inherently the more sustainable choice.

But is a new build really the most ecologically sensible solution?

In fact, the modernization and energy-efficient upgrading of existing buildings is one of the most effective measures for permanently reducing the real estate industry’s CO₂ emissions. Every new building generates significant amounts of so-called “grey emissions” during construction – CO₂ released through demolition, material production, transport, and construction processes.

In contrast, the comprehensive renovation of an existing building largely eliminates these emissions: The building’s structure is preserved, while targeted investments in energy efficiency significantly extend its life cycle and drastically reduce ongoing energy consumption.

Modern technologies – from heat pumps to photovoltaics to intelligent control systems – can be integrated into existing properties just as easily as new buildings. Furthermore, renovated properties often benefit from established, central locations with existing infrastructure and high site quality – an ESG factor that should not be underestimated in a social and economic context.

For institutional investors who view ESG criteria not only as a regulatory requirement but also as a strategic lever, modernized existing properties offer an attractive opportunity: They combine ecological responsibility with economic rationality. The ESG performance of such properties can be documented through appropriate certifications such as BREEAM, DGNB, or LEED, thus further increasing their market attractiveness.

Shouldn’t investors who truly want to make an active contribution to sustainability and reducing CO₂ emissions focus on comprehensively modernized existing properties rather than on supposedly “green” new buildings that often have a high ecological footprint right from the start of construction?

Sustainability doesn’t begin with demolition – it begins with conscious use of what already exists.
