Structure: Folder Input-Loadprofiles (.csv files): contains the loadprofile for DHW consumption that is used for all simulations & the original load profiles for SH supply and return & the scaled profile for SH supply for the 60 and 90 kWh/m^2 house Folder Parallel variants: Matlab script generates the bardiagram to compare return temperatures for the parallel variants; the Excel of the format "Temp_Loadprofile_xxx.xlsx" contain the simulation output from Polysun and are the input files for the Matlab script The subfolder Analysis-Excel contains for each variant an Excel sheet with the output from Polysun and an analysis in Excel (Return temperature classes & time below certain temperature levels in the left buffer tank & DHW tank) Folder Cascade: Matlab script generates the bardiagram to compare the return temperature of original and cascade version; the Excel of the format "Temp_Loadprofile_xxx.xlsx" contain the simulation output from Polysun and are the input files for the Matlab script "Analysis_Loadprofile_Cascade.xlsx" contains the output from Polysun and an analysis in Excel (Return temperature classes & time below certain temperature levels in the left buffer tank & DHW tank) "Analysis_Supplytemp_SH.xlsx" evaluates the total amount of time, when the supply temperature to SH is 1, 2 or 3°C below the required supply temperature The subfolder Bypassvolume contains a Matlab script that generates the diagram showing the flow rate of the bypass pump; input data (as output from Polysun simulation) for this is either the file "Bypassvolume_Summer.xlsx" or "Bypassvolume_Winter.xlsx", depending on the file small adaptions are to be made in the Matlab script; "Analysis_Bypassvol.xlsx" evaluates the increase of return temperature due to running of the bypass pump Folder Scaled_Cascade: Matlab script generates the bardiagram to compare return temperatures for the cascade variants with scaled heating energy demand; the Excel of the format "Temp_Loadprofile_xxx.xlsx" contain the simulation output from Polysun for the compared versions and are the input files for the Matlab script "Analysis_Cascade_scaled_xx.xlsx" contains the output from Polysun and an analysis in Excel (Return temperature classes & time below certain temperature levels in the left buffer tank & DHW tank) for the two variants with scaled heating energy demand
