Environmental sustainability metrics for effective heat demand management in integrating buildings

Abstract

For buildings with a sectoral role in decarbonisation, the main focus for energy and environmental sustainability is on-demand management and control. In this context, managing energy efficiency in systems is basically a valid approach for the development of demand management as a tool, especially for the management of green transition technologies and smart building applications. In this study, the model, which is exemplified by the analyses based on analytically derived data developed for integrated buildings with significant potential in the building sector, is examined with an entropy-based approach together with two environmental impact metrics. In particular, with the entropy-based approach, the exergy efficiency of the reference building and the resulting exergy destruction are discussed separately. The study found a thermal efficiency of 28.35% and an exergy efficiency of 25.01%. In this context, depending on the entropy production, the Environmental Potential Index (EPI) of the E1 and E2 components of the building was found to be 0.716 and 0.682 on average, respectively. On the other hand, the average sustainability index was found to be 0.399 for E1 and 0.386 for E2. According to these analyses, the average energy efficiency for E1 was 43.8%, while the average for E2 was 40.3%. In this context, the whole process shows an effective performance for the boundary conditions of the building together with possible demand management. At the end of the study, suggestions for building management were developed to improve energy and environmental sustainability.
