In residences, which have a large share in the consumed energy, it is considered important to reduce the amount of energy used. Although many studies are conducted in this field, studies on the use of local materials and costs in renovations are insufficient. For this purpose, a renovation approach was made through a Yapı Konut Kooperatif production selected as a study area in Avanos district of Nevşehir Province. The Bep-TR regulation, which is mandatory in our country, and the Bep-TR application, which is dependent on the regulation, were selected as the method in the study. The current energy status of the determined residences and the energy consumption and carbon emission amounts after the proposed renovation approach were determined through the selected program. The current energy classes of the buildings were determined as F156. The proposed renovation approaches were planned in a way that would meet the legal obligations for the energy class of the building (C 99). In addition, the energy values and costs of the stone coating application, which is a local material, were evaluated in the renovation approaches. In the study, it was observed that 43% energy and 44% carbon emission savings were achieved in two different renovation proposals. It was observed that the cost was high in the case of using local materials. However, stone cladding was seen to be preferable due to its high durability and sustainability. The study is expected to guide energy-efficient renovations in mass housing.}, publisher={Gazi Üniversitesi}
