This dataset contains optimisation results and figures used in the dissertation “Algorithmische Systemplanung raumlufttechnischer Anlagen”. It includes an overview table, detailed HDF5 result files, figure files, and JSON metadata for each figure. The JSON files make it possible to trace each dissertation figure back to the numerical data and optimisation results used to create it. The HDF5 files contain the detailed results of individual optimisation runs, including model data, solver information, and postprocessing values. The overview table facilitates searching and comparing the optimisation runs without opening each HDF5 file. Overall, the dataset is provided together with the associated research code publication (https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/5473) to support the FAIR publication of the dissertation-related research outputs.
