This dataset was used to plot the figures in the paper of "Modelling of District Heating Systems: Comparative Evaluation of White-box Modelling Approaches" on the conference of CLIMA 2022.The dataset includes:1.Comparison of free-floating temperature of Case 1 in both Modelica Buildings library and EnergyPlus;2. Heating demands of detached house 1 in Case 1 against Case 4 from two software;3. Annual energy consumption of iterative cases from two software;4. Heating system variables of Case 4 from two software;5. Comparison of simulation time on two software.
