In order to calculated the points relative to NC-v4 EAc2 - Optimize energy performance shall the produced electric energy from a renewable source that is sold to the national grid be considered (e.g. subtracted from the energy cost) too? Or only the part that is used onsite?
Shall its energy cost savings be evaluated with a cost rate equal to that one of the purchased electricity? Or shall the energy cost rate that the national grid administrator pays be considered?

So it sounds like you have an on-site renewable energy system. Some of the power flows to the building and some to the grid? Who owns the system? How is the power procured by the project?
The cost impact is determined using the same virtual rate from the proposed energy model for both renewable production and energy consumption.

Thanks, Marcus.
Some of the power flows to the building and some to the grid?
Yes
Who owns the system?
The owner of the building.
How is the power procured by the project?
PV panels installed on the roof.
So, if I understood properly, the energy cost savings shall be evaluated with a cost rate equal to that one of the purchased electricity, correct?

All of the renewable production should count assuming that the RECs have been retained or replaced.
Yes use the same rate.
