A case on energy retrofitting interventions in a heritage building

Purpose This study examines the adaptation to future climate conditions of energy retrofitting measures, the performance of which is considered to be effective today. It is aimed to analyse the energy performance of retrofit interventions that respond positively to today's climate conditions in future climate conditions. Design/methodology/approach In the methodology of the study, the diversity of energy retrofit interventions in the literature is constructed within the framework of three different conceptualised intervention packages. Each conceptual intervention package is evaluated under three different climatic conditions for the years 2023, 2050 and 2080 and 9 different energy improvement scenario models are created. The base model in the study represents a cultural heritage building and the study presents a case study. Findings According to the findings, the most effective energy retrofit package in the climatic conditions of all years analysed is the intervention package created with renewable energy sources. The second package in energy optimisation is the package with an innovative concept using aerogel materials. Although the base model improves the energy performance, the poorest performance in the comparison of the three packages belongs to the package that includes interventions that are frequently used in the current literature. Originality/value This study presents original research to the literature in terms of addressing the role of current and future climate conditions in energy retrofit. The study findings provide quantitative data on the revision requirements for new studies of energy retrofit interventions that are frequently used today.
