Minor fixes for retrofit calculations

[ekatef]

Changes proposed in this Pull Request

Fixing some minor discrepancies for buildings area calculations in build_retro_cost script. In particular:

1. U-values for Poland are represented in hotmaps dataset as Construction features (U-value) instead of Construction features (U-values);
2. "Total" feature is contained in subsector column, not in detail one.

The solar global radiation was somehow off, our updated values are taken from this source (which is also referenced in the script): http://www.episcope.eu/fileadmin/tabula/public/docs/report/TABULA_CommonCalculationMethod.pdf

With the suggested changes, I was able to reproduce the retrofitting costs from "Mitigating Heat Demand Peaks" Study, Supplementary Material, Table 3. 🎉

Just a quick note, in line 950, I need to un-comment renaming the column from country to country_code, otherwise I'll get an error (country_code does not exist). But could be that it's just me?

Could you confirm whether a renaming of country/country code is necessary?

Then, this can be merged.

Good day, I have also applied the changes and observed the produced retrofitting costs. The resulting file is quite similar to the aforementioned paper's results in terms of order of scale. I have observed some differences for various countries (AT, BA and etc). Regarding uncommenting line 950, I have first tried as it is (commented) and I did not see any error. When I have uncommented it, I have faced an error.

@ekatef and I have discussed the above mentioned issue about renaming, but it turns out that the error is on my end. Not sure what's wrong, but I think it's clean as is. Ready to merge.
