Energy-efficient modernisation

Energy-efficient modernisation of a neighbourhood: Optimisation approach through modular refurbishment procedures, taking into account transfer and implementation obstacles; sub-project social science support


German Federal Ministry for Economic Affairs and Energy

Duration July 2018 – June 2020


Achieving the Federal Government’s climate policy goals of showing a climate-neutral building stock by 2050 requires a holistic approach. New buildings and existing buildings must be considered equally. Demographic aspects such as the age pyramid and housing shortages, especially housing for people with lower incomes, are issues that must be interlinked with energy efficiency issues. Upcoming repairs and renovations as well as their financial expenditure must be approached, planned and implemented in an interdisciplinary and transdisciplinary manner. This is the only way to counteract obstacles and concerns on the part of owners and tenants.

The aim of the project is to combine passive and active energy-saving measures to meet the EnEV standards, even for buildings that are difficult to renovate. Selected model project is a quarter of a building cooperative in Munich. A part of the heating load is to be covered by modular repair procedures including the outer shell of old existing buildings as a thermally activated surface. The current regulation of heating cost accounting is questioned to the effect that part of the final energy used serves to maintain the building. For this part no individual heating cost account takes place.

The project results are reflected economically, technically and ecologically. Within the framework of a participative approach, individual comfort requirements and the user behaviour of the residents are considered from a social science perspective. Implementation obstacles and beneficial aspects in the refurbishment process are evaluated. In addition, regulatory obstacles will be investigated. This will be accompanied by transparent communication in the sense of practice-oriented information management in order to identify and resolve any conflicts that may arise in the process at an early stage.
