Buildings are one of the largest contributors towards emissions. The EU countries plan to cut 80% of the emissions by 2050. The aim of this article is to model two different photovoltaic (PV) based energy systems integrated either with new or old building in a district and to conduct emissions comparison against a reference city level energy system in the Nordic region. The main novelty lies in the analysis of the CO2 reduction potential from the grid and buildings. The relative emissions reduction is found to be 85% when the new building is integrated with PV+heat pump and seasonal storage system compared to the reference energy system. The emission reduction cost of such a system is 8.59 €/kg CO2/yr. Such systems can support in reaching the EU’s emissions target.
