Importance of Sustainability in Construction

In Life cycle CO2 assessment of concrete by compressive strength on construction site in Korea, Junghoon Park, Sungho Tae, and Taehyung Kim build on the reduction of life cycle carbon dioxide building emissions and its increasing importance. This article will provide a good basis for research into the construction of a sustainable building. Various aspects that support the article’s academic reliability include its appearance in a relevant academic journal, the Renewable and Sustainable Energy Reviews. In addition, the authors are academics at the School of architecture and architectural engineering. Finally, various articles according to result on Google Scholar have cited this article in question.
Text Summary
The authors first classified the concrete production processes into various stages, including production of the raw material, transportation of the material, and production of the cement (Park et al, 2012: p2942). Following science-based quantification of carbon dioxide and energy consumed and emitted at all stages, a review on their environmental impacts was done. Using the results, the authors sought to determine measures for improvement of environmental conditions. For the raw material stage of production, they computed the consumed energy and emitted carbon dioxide associated with admixture, cement, and aggregate. The total emitted carbon dioxide was then computed using science based emissions per unit concrete volume. For the transportation phase, they computed the total

consumed fuel by the transporting vehicle, examining the freight vehicle load, its fuel efficiency, and distance travelled. Finally, the assessment of emission during concrete production was computed using daily consumption of energy at the batcher plants. The production process was split into storage, transportation, measurement, and mixing stages with emission for each stage analyzed (Park et al, 2012: p2943), which when used for the Apple building will ensure it fits into the walking tour’s sustainability project. The article then moves to science based assessment of carbon dioxide emissions in the concrete lifecycle. They analyzed common Portland cement, coarse aggregate, fly ash, blast furnace slag ground, water, fine aggregate, and water reducing admixture in various proportions (Park et al, 2012: p2944). These components are highly used by constructors all over the world. They then classified data for around five hundred and sixty different proportions of mix, which they classified by the season, admixture type, and strength again important for the Apple building to fit within the Sydney walking tour’s insistence on low carbon emissions. The authors finally drew several science-based conclusions from the research. First, carbon dioxide emission lifecycle from concrete saw a linear increase as the concrete’s compressive strength is increased (Park et al, 2012: p2946). Concrete produced during the winter at the same strengths of compression gave an increase of 5% in emissions compared to concrete made in standard season. They also found that concrete with admixture emitted approximately 47% less carbon dioxide. In addition, emission was reduced by mixing concrete with over 10% blast furnace slag

Summary

The report will focus on using these methods to reduce emission of CO2 during construction of the Apple building as concrete’s compressive strength is increased. By this, the building will fit into the Sydney walking tour alongside the other buildings on the tour by being sustainable. …
