Development of the Life Cycle Analysis (LCA) Method in calculating Embodied Energy Materials on Residential Buildings

Abstract One of the benefits of BIM towards a sustainable design is it can make a design system that will calculate the building energy in aim to give alternatives on energy-efficient design. BIM can be utilized to integrate the calculation of Embodied Energy (EE) Building Materials with the Life Cycle Analysis (LCA) method. EE calculation could be easier for architects; hence, the architects can understand the impact of carbon emissions caused by construction activities during the design process. This paper aims to provide an overview of the use of BIM in calculating the EE value of the designed building material on the apartment project. Since the development and construction of flats and apartments, especially in Indonesia, are growing fast, this will give highly environmental impact if it is not properly controlled. The results showed that the BIM implementation in calculating the EE value could be done. Collaboration with other platforms can also be done to make the final calculation, and it will be displayed in attractive data visualizations. The percentage comparison of the embodied energy value in all of the building component materials can also be seen in the results of the analysis. In this case, the highest embodied energy percentage is the structural component, which is 53.16%. It is hoped that the development of this calculation method will contribute to the development of LCA so that EE can be easy to be calculated and have a good impact on the construction industry in the future, especially in Indonesia.
