| description |
Emission of carbon dioxide (CO2) from construction sector has been estimated to contribute nearly 50% of total global emission. Identifying the sources of emissions and understanding their function and relationship to construction activities are essential if
not crucial, in mitigating this global crisis. Sustainability research has been initiated to reduce and eradicate the carbon emissions problem, especially in the construction industry. This study evaluates the carbon footprint of the main machinery and materials
used in constructing a five-storey hostel that implemented Industrialised building system (IBS) method in Perlis, Malaysia. A life cycle assessment (LCA) framework is used in conducting a partial LCA from pre-design to construction phase. LCA was
performed in accordance with the four-step which is goal and scope definition, inventory analysis, impact assessment and interpretation. It also used as a method to systematically analyse the environment assessment. Results showed that the five-storey
hostel in Pauh Putra,Perlis has obtained a total IBS Score of 73.4%. Theindirect carbon
footprint hotspots are coming from prefabricated sandwich panels manufacturing
factory, especially one which manufactured by boiler machine. During this process,
4.52 tonnes of CO2e are released by the machines. This is due to the extensive energy
used for steam heating and high engine rating for the boiler. Cement releases about
369.04 tonnes CO2e. Its direct carbon footprint hotspots are caused by the large quantity
of cement used in the shotcrete mixture and its high extraction–production CO2
emission values. Meanwhile, overall onsite materials generated 65.60% of the total
carbon footprint. Whereas, the direct carbon footprint hotspots by the fuel machinery at
the construction site were heavily from excavator and construction of building
superstructure task, which yields 81.59 tonnes CO2e and 86.76 tonnes CO2e,
respectively. This is mainly due to the extensive use of both types of machinery in the
daily construction activities. These results can be used as one of the samples in many
problems to determine an adequate understanding the impact of IBS construction to
carbon emissions in Malaysia. |
