Özet:

Energy plans are at the center of countries' development plans. The share of buildings in energy consumption is about 40%. Energy consumption in buildings can be reduced by 25-45% with the measures taken. The European Union has published the Energy Performance Directive on Buildings (EPBD) to reduce the energy consumption of buildings. European Union member and candidate countries are obliged to fulfill the provisions of the regulation. Turkey is among the candidate countries for accession to the European Union (EU). Therefore, the energy consumption of the existing buildings and the reduction of CO 2 emissions were examined in this study. Since The Intergovernmental Panel on Climate Change (IPCC) predicts that global temperatures will increase by a range of 1.1°C to 6.4°C by the end of the twenty-first century, future climate data were also taken into consideration in this study. For the study, measures were determined to achieve the EU's total CO 2 emission reduction targets. A mass housing settlement built by the Housing Development Administration (TOKİ) in Isparta has been identified as the study area. Improving the heating systems of these buildings, increasing the energy performance of the building envelope and the production of electricity with photovoltaic (PV) panels were studied in this study. As a result of the study, it was determined that it has 66% CO 2 emissions in 2020, 79% in 2030, and 84% less in 2050 compared to 1990.
