Material quantities of foundation systems in building structures
… are three major areas in which buildings consume energy: (1) energy consumption from operational processes, such as heating and electricity, (2) energy from building material production and supply, and (3) energy from design and construction processes. In recent years, improved operational energy …

Assessment of beam-to-column joint behaviour in steel-timber composite systems
… structural components with the highest levels of embodied energy and carbon. Accordingly, replacing conventional reinforced concrete slabs with timber slab can potentially reduce the embodied energy and carbon footprint and provide opportunities for effective carbon sequestration. The light-weight …
