CO₂ Life-Cycle Assessment of Prefabricated and Cast-In-Situ Structure Using Monte Carlo Simulation

Abstract

CO₂ emissions have become a part of common vocabulary as a result of the significant negative effects of climate change. Through the supply of buildings and infrastructure for the smooth operation of a business, the construction sector plays a vital role in the growth of an economy, both directly and indirectly. However, due to carbon emissions from materials and energy, this business is currently facing significant challenges. Prefabrication has grown in popularity in nations as a result of its several benefits, including quality control, waste minimization, onsite and offshore parallel to coordination, and so. It’s also been identified as a crucial approach for reducing carbon emissions caused by buildings. However, there has been little study into reducing carbon emissions in prefabrication through the use of advanced technical artefacts such as Building Information Modelling (BIM), which are emerging from the technology realm. The goal of this article is to provide a BIM-based method for calculating carbon with the usage of the PLCA method. During the materialization stage of a prefabricated construction project, there is a decrease. Partial Life-cycle Assessment (PLCA) is an efficient and effective technique for estimating carbon emissions from new building construction, according to the study’s findings, and prefabrication reduces carbon emissions when applied. After computation, the comparison is being done using the Monte Carlo simulation to find the percentage difference and this software helps to find the iteration for different scenarios. The study adds to the corpus of knowledge on carbon emissions reduction through prefabrication. Contractors, house buyers, and authorities who are continually looking for methods to build a circular economy should be aware of life cycle assessment of CO₂. In this study, we are exploring how pre-fabricated structures are the need of the future and their usefulness to the very extent to determine the emissions at the production, transportation and construction phases of the building life cycle. And determine the amount of CO₂ emissions in the pre-fabricated structure by comparing it with the cast in situ and to differentiate the result by creating a simulation through Monte Carlo analysis.
