Assessment of Cross Laminated Timber with Coconut Wood as Primary Material
摘要
Alternative engineered wood products have great potential to replace concrete and steel in the structural application. The environmental footprint of cross laminated timber has been discussed widely as being advantageous. The aim of this study is to assess the reduction in embodied energy (EE) and Embodied Greenhouse Gas (EGHG) by using of Cross Laminated Coconut Timber (CLCT) as a structural component in a passive building as compared to the same building design using hypothetical conventional RCC structural system. The study will help in identifying the important strategies for the reduction of embodied energy and embodied greenhouse gas consumption at building level. Process analysis, which employs a bottom-up approach using physical quantities to estimate embodied energy is used to compare the embodied energy (EE) and embodied greenhouse gas (EGHG) consumption of Cross Laminated Coconut Timber (CLCT) and RCC Building. It is found that the cumulative embodied energy of the CLCT house is 291.11 GJ, while that of a similar reinforced cement concrete building is 399.06 GJ. The embodied energy of the CLCT building is 27% lesser than the RCC building. Further, the embodied greenhouse gas of the CLCT building is 65% lesser than a similar RCC building. Overall, in terms of embodied energy and embodied greenhouse gas consumption, CLCT building outperformed the RCC building.
