Sustainable development in listed districts: CO ₂ neutral World Heritage Speicherstadt Hamburg

To achieve Germany's 2045 goal of climate-neutral building stock, the integration of renewable energies in retrofitting is necessary. The project ‘CO2-neutrales Welterbe Speicherstadt Hamburg’ situated in the historic warehouse district, focuses on the sustainable heat supply in listed buildings. The project consists of two main approaches: a practical approach combining historically sensitive components for heat supply to create a comprehensive energy retrofitting concept with renewable energies in the listed area, and a methodological approach using Building Information Management (BIM) to integrate various simulation models and centralize outcomes efficiently. This enables a holistic and energy-efficient retrofit, addressing flow-specific, thermal, and ecological aspects, thereby marking a significant step toward achieving a CO2 neutral listed building stock.
