Fig. 7 shows the imported CO2-eq emissions versus the dLCC for all building EEM combinations for each H/C-EGS. The imported CO2-eq emissions mean the released CO2-eq emissions associated with the imported energies, whereas the exported CO2-eq emissions mean the displaced CO2-eq emissions in the grid associated with the exported energies from renewable Difloxacin sources, using the symmetric CO2-eq emission factors. The imported CO2-eq emissions are in range of 13.1 kgCO2/m2a and 76.2 kgCO2/m2a. It can be noted that for biomass-based CHP and CCHP systems, the difference between the imported CO2-eq emissions between the building EEM combinations of BSSP 1 and BSSP 2&3 is very small. The building EEM combinations with BSSP 2&3 have always imported CO2-eq emissions lower than ones with BSSP 1. The net CO2-eq emissions can be defined as the difference between the imported and exported CO2-eq emissions. From the net CO2-eq emissions point of view, the building EEM combinations with BSSP 2&3 have lower net CO2-eq emissions than ones with BSSP 1, except the ORC. The reason is mainly related to the very low CO2-eq emission factor of pellet fuel compared to other energy carriers. As concluded in  for net CO2-eq emissions, as long as the biomass-based CHP systems are operated under a thermal tracking strategy, the possibility of producing electricity which can be utilized by the electrical demand or exported to the grid, is decreased with highly efficient thermal demands, leading to an increase in the net CO2-eq emissions. Replacing the VCR by AC with the PB and all biomass-based CHP achieves reduction in the imported CO2-eq emissions and net CO2-eq emissions as well. Significant reductions of the imported CO2-eq emissions of 17%, 16%, 15%, and 14% are obtained when the AC is implemented instead of VCR as a cooling system with SE, ORC, IFGT, and ICE, respectively. Once the displaced CO2-eq emissions in the grid associated with the exported electricity is taken into account, the net CO2-eq emissions reduces by 41%, 39%, 23%, and 20% with IFCT, ICE, ORC, and SE, respectively, when the AC is implemented instead of the VCR.
