Discrepancy in CTS Demand Assignment to Zensus Cells without CTS Buildings

[khelfen]

Hey @CarlosEpia ,

I'm not sure if this is a bug or something I'm missing. Here is the situation:

• In my status quo scenario for the services sector, the demand.egon_demandregio_zensus_electricity table shows a CTS demand of about 120 TWh, which seems plausible.
• This demand is spread over 500k zensus population IDs.
• However, in the openstreetmap.egon_cts_buildings table, which I believe contains all CTS buildings, there are only 100k zensus population IDs.

My question:
What happens to the CTS demand assigned to zensus cells that do not have corresponding CTS buildings? Is this expected or does it indicate a possible mapping inconsistency?
