Ratio of UE to FE in buildings seems off #174

Open fschreyer opened 2 years ago

fschreyer commented 2 years ago

The ratio of useful energy to final energy for heat pumps in buildings seems quite high (around 6-7 by 2050):

Also UE/FE for resistive heating goes down to about 0.5.

Is this intended or a reporting error?

I checked this and there seems to be a problem in the disaggregation of resistive heating and heat pumps in EDGE-B that leads to a mid-term peak of heat pump efficiency to about 6. The heat pump efficiency should rather approach 5 in SSP2. But your numbers are even higher. And the drop of efficiency of resistive heating down to 0.5 is something I cannot see in the EDGE-B results. I'll have to follow up on this to see, if this is a reporting issue. Now that I looked at the correct scenario I found exactly the numbers you mentioned in the EDGE-B resuslts and as said above this is due to a problematic disaggregation of resistive heating and heat pumps in EDGE-B. I will fix this and include this fix for the next round of input data preparation. Sorry for this. I never saw this because the issue is most prominent in an extra scenario that we calculate for European regions.
