Four cities from different climate zones (Aydn, Trabzon, Malatya, and Sivas) were selected for the analysis which was carried out with two different insulation materials. Results showed that insulation thicknesses were determined between 0 - 0.179 m, with the amount of 0 - 235.053 /m2 of energy saving and 0 - 11.53 years of payback period depending on various fuel and wall types.eninfo:eu-repo/semantics/closedAccessBlock pumice; External wall; Life cycle cost; Optimum insulationArticle3721131032-s2.0-84880055311Q3
