OptiPort
Collaborative project: EnOB: OptiPort – Development and evaluation of optimized climate-neutral refurbishment paths for the portfolio management of multi-family housing stocks taking into account restrictions
Project management: Dr. Andreas Velte-Schäfer
Funding period: 01.10.2024 – 30.09.2027
Funding code: 03EN1100D
Funding body: Federal Ministry for Economic Affairs and Climate Action (BMWK)
Promoter: Forschungszentrum Jülich GmbH (PtJ)
Housing companies play a decisive role in achieving the goal of a climate-neutral building stock. Unlike private actors, they always have the entire portfolio in mind when it comes to energy-efficient refurbishment and replacing heating systems but have so far often taken a less structured approach to developing a refurbishment strategy. Some of the existing tools on the market are not very practical and only take the specifics of companies into account to a limited extent.
In the OptiPort project, a tool is to be developed together with the housing industry in order to create an optimized refurbishment roadmap for multi-family house portfolios that takes into account the company-specific framework conditions. The result is a roadmap for the portfolios examined, which shows which measures should be implemented on which buildings and at which times in order to make the best possible use of the available resources and capacities. The close involvement of the housing industry ensures that the tool delivers practical results that are robust in the face of uncertainties and can be used for different inventory data qualities and over the long term.
Subproject: Data acquisition, data preparation and modeling
At INATECH, the data required to calculate an optimized renovation roadmap is identified, compiled and clustered. In addition, the required modeling depth for the calculation is determined and the robustness of the results is checked using sensitivity analyses.
Project partners: Institut für ökologische Wirtschafsforschung (IÖW), RWTH Aachen University, Fraunhofer ISE
