Abstract

Urban regeneration practices create an opportunity to make many different improvements in cities along with earthquake safety. Building renewal at parcel scale, which is seen as a type of urban regeneration practices in Turkey, has an impact on a wide area throughout the city due to the large number of individual projects. The concept of sustainability gains importance in the construction sector, especially because of the high energy, material and water consumption of buildings, and the large share of buildings in waste generation and greenhouse gas emissions. Implementation of urban regeneration practices by using methods that are suitable for local conditions, created in line with legal requirements and providing environmental, economic and social sustainability principles are considered necessary in terms of sustainability in the built environment. The aim of the study is to develop a decision model for the design process of residential building renewal that complies with the conditions of parcel-scale building renewal practices in Turkey, covers the three components of sustainability, and provides sustainability cost-effectively by evaluating the cost. In this context, firstly, an expert panel was formed with the Delphi technique, then an expert questionnaire was applied and a decision-making model was constructed with the analytical network process. The model setup created at the last stage of the study was tested with a case study. As a result of the case study, a design alternative that has a lower thermal permeability value than other alternatives, uses renewable energy, has low-impact materials, and has systems that reduce water use was determined as the most suitable alternative by the participants.
