Methodology applied for calculating the heat demand time series. Starting from spatial temperature and wind speed time series from the ECMWF ERA-Interim dataset, gas standard load profiles are derived according to BGW7 and BDEW8. The time series are weighted with population data from Eurostat GEOSTAT dataset, spatially aggregated, normalized and scaled using the EU Building Database.
