For space heating, the annual demands are converted to daily values based on the population-weighted Heating Degree Day (HDD) using the `atlite tool `_, where space heat demand is proportional to the difference between the daily average ambient temperature (read from `ERA5 `_) and a threshold temperature above which space heat demand is zero. A threshold temperature of 15 °C is assumed by default. The daily space heat demand is distributed to the hours of the day following heat demand profiles from `BDEW `_. These differ for weekdays and weekends/holidays and between residential and services demand. The space heating demand can be exogenously reduced by retrofitting measures that improve the buildings’ thermal envelopes [Refer to PyPSA-Eur-Sec Config file, line `212 `_]. + +.. literalinclude:: ../config.default.yaml + :language: yaml + :lines: 212 Heat demand is split into:
