Abstract :

Buildings have a significant impact on cultural and climatic changes due to their resource and energy consumption, a main challenge for humanity in current society. Energy in buildings has two components: embodied energy and operational energy. Scientists worldwide study strategies to reduce building energy consumption, focusing on either operational or embodied energy separately. Thus, there is a gap in social studies regarding the impact of embodied energy on operational energy in buildings. Additionally, energy studies on educational buildings with a social approach are scarce. The primary aim of this research is to develop and test a predictive model of the impact of embodied energy on cultural changes and operational energy in green school buildings. It also examines the moderating role of the embodied energy of the exterior wall core in the causal relationships of the conceptual model. The researcher used a quantitative approach and a systematic methodology with advanced variance-based structural equation modeling techniques to test the hypotheses. After data collection and screening, 702 samples were tested for validity, reliability, and model fit of the external model, and the hypotheses were tested within the structural model. The results, with R2 = 0.704 and 0.755 in two structural equations, indicate a powerful explanation of the variance in cooling load and heating load (i.e., operational energy) based on embodied energy behavior. This suggests the model can predict 70-75% of the influence of embodied energy on operational energy.
