Hello, regarding my previous post I have one more doubt: having the building with a biomass system, in EAc1 when calculating the thermal energy do I have to use the local gas cost or the local biomass cost? If I use the local biomass cost I would come through a weird situation: the higher the local biomass cost is, better the building would be classified in EAc2 (because if the quantity of renewable energy is higher, also the building will classified better).
Thanks,
Gabriele
