More detail of distribution of buildings' heat consumption for retrofitting/efficiency measures

[nworbmot]

Stefan Petrovic from DTU mentioned a database from Vienna, DTU, called TABULA: http://episcope.eu/welcome/ There's a nice distribution of kWh/d/household heating demand in the UK in Figure 6 of https://doi.org/10.1039/C8EE01157E

Should look on Odyssee for retrofitting/efficiency data (e.g. progress per year).

Aggregated costs for measures in Europe, based on another source, for PRIMES on page 43 of:

They also have a webtool from Episcope with 21 EU countries and different building types, comparing existing state, usual and advanced refurbishment http://webtool.building-typology.eu/#bm) for 16 EU countries they have also data about the number of buildings and the development until 2050 http://episcope.eu/communication/download/

The JRC-IDEES database includes for every country, the total "Number of households" and the “Number of new and renovated households”.

The EU Building Stock Observatory provides per every country:

• The number of buildings by age category. See, for instance, Figure 37 of the In depth analysis supporting the EU strategy “A clean planet for all”
• U-values for building envelope/windows/roofs for every age category.

So, one strategy that we could implement is as follows For every country and age category:

1. Use the U-value to estimate which type of renovation is needed (light/medium/deep).
2. Use the table on page 43 PRIMES to estimate the energy savings and the cost of such retrofitting.
3. For every country, add the different building categories to create a curve of “Heat demand reduction” vs “Cost”.
4. Check that the approach is working using existing reports for Denmark and Germany and apply it to the rest of countries

Figure 7 in this paper https://www.sciencedirect.com/science/article/pii/S0360544216308064#sec5 includes a figure similar to that of the synergies paper for CZ, HR, RO, IT. This could also be used to validate the method.
