Primary energy and CO2 emissions for a district city and a suburb

Open access


In countries of the European Union, the proportion of buildings in the overall energy consumption represents 40% and their proportion in CO2 emissions 35%. Taking into account dependence of the European Union on import of energy, this represents large quantity of energy and CO2 emissions, in spite of the fact that there exist effective solutions for reduction of building energy demand. In Directive 20-20-20, the European Union adopted three main commitments of fulfillment criteria by 2020. On the basis of this directive, the Slovak Republic declares support of renovation of apartment dwelling houses. Taking into account the fact that state subsidy can be obtained only once, and energy requirements of the European Union are increasingly stricter, a comprehensive approach to renovation of buildings is inevitable. At the same time, it is inevitable to propose the renovation of buildings taking into account requirements stated for buildings for year 2020. Two areas were compared within the case study taking into account primary energy and the quantity of CO2 emissions. Both areas have the same built-up area, but one of them is a district city and the second is a suburb. From results it is obvious that the quantity of primary energy is lower by 88% in the district city than in the suburb. The quantity of CO2 emissions is lower by 69% in the district city than in the suburb.
