Assessment of energy efficiency improvement measures in existing residential buildings in Turkey

Abstract

Existing buildings are responsible for a considerable amount of global carbon emissions and energy consumptions. Improvement of existing building stock in terms of energy efficiency is needed to achieve energy and carbon saving targets. In this thesis, possible energy efficiency measures for a standard building assumed to be located in cities from each climate region of Turkey are analyzed and assessed in terms of technical and economic aspects with the purpose of investigating the saving potentials. The economic savings as well as energy and carbon savings of all the measures, investment costs and payback periods are compared with each other. According to the findings, a more feasible approach which depends on prioritization of the energy efficiency measures can be suggested for the buildings with different characteristics in different climates. Energy, carbon and cost savings potentials in each climate region and in each city which is chosen as the representative of region in this study are stated and total saving potential of Turkey’s building stock is estimated. The approach proposed in this study can help decision makers to plan and evaluate their energy efficiency retrofitting strategies by guiding them to select appropriate energy efficiency measures to achieve maximum environmental and economic benefits.
