Energy-ecological analysis of large building stocks

Project duration:

Funding organization:
Bavarian State Ministry for Housing, Construction and Transport

Brief summary:

The Free State of Bavaria, per the Bavarian Climate Protection Act (BayKlimaG), has committed to achieving a climate-neutral state administration by 2028. This commitment entails the task of realizing a climate-neutral building stock as well. This includes developing a suitable refurbishment strategy for the energy improvement of the property portfolio. The challenge lies in the large number of different buildings with varying uses, construction ages, and conditions, as well as the data available for each building.

For this purpose, a tool is being developed to analyze the application of various refurbishment measures and energy standards on the building stock. Different strategies for achieving climate neutrality are integrated into the developed tool. The developed solutions are economically evaluated to ensure efficient implementation of these strategies and to communicate the alternative scenarios. Artificial intelligence methods are used to calculate the energy demand for heterogeneous buildings and different refurbishment scenarios. These calculations utilize data from a digital twin and existing databases to create reliable forecasts for energy efficiency, providing a sound basis for decision-making in implementing refurbishment measures.
