    Assessment of Sustainability and Efficiency Metrics in Modern Methods of Construction: A Case Study Using a Life Cycle Assessment Approach
    (2023) Hernandez, Hector; Ossio, Felipe; Silva, Michael
    The construction industry faces various sustainability challenges, and modern methods of construction (MMC) have been promoted as an effective alternative to mitigate environmental impact and improve productivity. However, to gain a thorough understanding of the benefits, there is a need for more objective data. To address this, the present study employs a simplified life-cycle assessment (LCA) methodology to evaluate a set of environmental and efficiency metrics in a case study. The study aims to demonstrate the benefits of using an MMC known as the "VAP system" by comparing it with its conventional counterpart built with reinforced masonry. Adopting the MMC resulted in significant reductions in embodied carbon (EC) and embodied energy (EE) related to materials, as well as a reduction in global warming potential (GWP), cumulative energy demand (CED), and construction waste. Additionally, it shortened delivery times and increased labor productivity. Furthermore, when both local and European parameters were considered in the evaluation, the percentage of materials circularity (PMC) was higher. The study concludes that the adoption of the MMC leads to higher sustainability by reducing carbon emissions, minimizing construction waste, and conserving resources. This research has significant implications for promoting the adoption of MMC globally, leading to more sustainable and efficient construction practices.

    Waste construction management in social housing projects
    (2012) Castillo Marín, Eduardo Andrés; Ossio, Felipe
    The construction and demolition waste in many ways impact the environment: They pollute the soil, the water, and the air. They change the landscape among other degradations of the ecosystem. Chile generates over five and a half million tons of construction and demolition waste a year. This figure represents about 10% and 30% of the total urban country waste. Although in Chile there isn´t an appropriate normative or law to regulate this type of waste to lead to a right arrangement in terms of waste. This study presents an arrangement plan of construction and demolition waste to build Social Housing based on the constructive chasing of social housing done in Santiago, Chile. To do that, the main constructive waste generated were first identified, then the registry of quantity about the typology of material, also the national normative of management and the possible alternative of waste management based on the valuation of reusing, recycling and energetic valuation. The waste management plan looks for recovering the economic value and the usefulness that those wastes could have of which waste might shock negatively on our environment. The study gives advice, responsibility, and actions that should be taken by the different constructive actors. On the other hand, the environmental and the economic impact are determined to the respective constructive enterprise. It also hands over the present normative of construction to implement this planmenos.
