Renovation Strategies for Energy Conservation in Multi-Story Residential Buildings in Turkey

Abstract

Reducing the energy consumption of existing and new buildings is necessary in the context of energy efficiency. This study emphasizes the importance of energy-efficient renovation of existing housing stock and the development of renovation strategies according to the TS 825 standard and climate characteristics across the different degree day zones of Turkey. The research proposes an energy-efficient renovation of a public housing project and analyzes the impact of these suggestions on building energy performance. The impact of renovations to improve the thermal performance of opaque and transparent components on the energy performance of the building is calculated using the Design-Builder simulation program, and the heating-cooling loads, electricity, natural gas, and total energy consumption are analyzed in the four zones. With the most cost-saving renovation suggestions, total energy consumption is reduced by 35.7% in Erzurum, 32.2% in Ankara, 27.3% in Istanbul, and 19.3% in Antalya. In residential building renovations in Turkey, especially in hot climates, it is essential to focus on energy-efficient design principles, increase the insulation thickness of opaque components, improve the thermal performance of transparent components, and install solar control where necessary to improve the energy efficiency of the building.
