| Abstract: | The construction industry is the largest consumer of concrete and steel worldwide, resulting in one-third of global carbon emissions. Achieving low-carbon buildings is a key concept to reducing carbon emissions and mitigating climate change. Wood is a carbon sink that absorbs carbon dioxide from the atmosphere and stores it in building elements until the end-of-life cycle. The reduction of carbon emissions is critical to addressing energy and climate issues. Due to safety and structural property concerns, the use of timber for structures is limited to low-rise structures. Tall buildings constructed with concrete impose high carbon emissions on the environment which has been overlooked on its embodied carbon more than the operational carbon. In this research, the multi-story concrete residential building is simulated into a Timberconcrete building used as a comparative case study. To ensure the validity of the building, the timber-concrete building is verified on its feasibility. The embodied carbon analysis and comparative analysis are performed between the two buildings in terms of effects on the material quantities, embodied carbon, and global warming potential. It is found that the Timber-concrete building has a significantly lower embodied carbon emissions compared to its existing-concrete building. Furthermore, comparative analysis showed the implications of building materials and components on its embodied carbon emissions. Overall, this study can aid architects, engineers, and construction teams to adapt and implement timber in the construction of tall buildings in the future. |
