ReKoeSan: Serial refurbishment – climate-neutral and socially responsible housing in the existing building stock

How can buildings be modernised in a climate-friendly, cost-effective and socially responsible manner? As part of a pilot project run by Stadtbau-GmbH Regensburg, two residential buildings are being renovated in succession in accordance with the ‘Energiesprong’ principle – whilst the buildings remain occupied and with particular consideration given to the tenants. The project team at OTH Regensburg is investigating the environmental, economic and social impacts of the refurbishment. The findings will be incorporated into a practical guide designed to facilitate the transfer of these approaches to other refurbishment projects.

What is the title of your research project?

Regensburg Königswiesen – affordable, sustainable regeneration (ReKoeSan)

Who is involved in the project?

Prof. Dr Petra Liedl (project lead, OTH), Prof. Dr Charlotte Thiel, Prof. Dr Sonja Haug and the research assistants Edda Currle, Mina Schneider, Jonas Wiederer and Paul Wickert

What is your funded project?

With the long-term aim of creating a socially responsible and climate-neutral neighbourhood, two residential buildings owned by Stadtbau-GmbH Regensburg are being energy-efficiently modernised as part of this pilot project. As part of a phased refurbishment based on the ‘Energiesprong’ principle, the project is being implemented using prefabricated building components and digital planning methods whilst the buildings remain occupied, with particular consideration given to the tenants. Scientific monitoring by the project team at OTH Regensburg is examining the buildings’ performance to analyse the impact of the refurbishment measures on the indoor climate, thermal comfort and energy consumption; the environmental, economic and social impacts of the refurbishment are being analysed using acceptance studies, life-cycle and cost-benefit analyses, as well as a social life-cycle assessment in accordance with UN guidelines.

What excites you about the project?

The project is particularly exciting because it takes a holistic approach and links the technical, environmental, economic and social aspects of building refurbishment. Carrying out the work whilst the building is occupied provides rare insights into real-world usage conditions and enables robust findings on building performance and user acceptance. The innovative serial refurbishment based on the ‘Energiesprong’ principle opens up new prospects for efficiency and scalability in the construction sector. At the same time, the comprehensive data collection on indoor climate, comfort and energy demand allows for well-founded analyses of the actual effects of the measures. The systematic compilation of the results in a guide ensures a high degree of practical relevance, which contributes to broad transferability.

How can the findings from the project be applied in practice?

The pilot project combines serial refurbishment, climate-neutral energy supply, the circular economy and social integration in a construction project that is both sustainable and affordable. The findings obtained during the accompanying scientific process are compiled in a guide for economically viable, climate-friendly and socially responsible building refurbishment, to enable the findings to be applied to other refurbishment projects.
