Net primary energy consumption in the building operation
the building operation, the avoided GWP related to the saving of primary energy
arisen from the on-site electricity generation is reported.
In order to assess the environmental effects when shifting the LH from the
nearly Net ZEB condition toward the Net ZEB target, the energy and environ-
mental impacts arisen during the building life cycle (see Table
5
) are compared to
