Abstract(s)
A dissertação aborda a temática dos impactes ambientais provocados pela utilização de materiais na Indústria da Construção, pois estes produzem alterações ambientais significativas, associadas em grande parte às atividades humanas e construtivas.
Nesta perspetiva, este trabalho aborda dois dos parâmetros que mais influenciam os impactes ambientais: a energia incorporada nos materiais de construção, no que concerne ao consumo de recursos energéticos, e as emissões de dióxido de carbono (CO2).
O objetivo do presente trabalho consiste na quantificação das necessidades energéticas e emissões de CO2, de um projeto de nova construção com manutenção de fachadas, de um edifício pombalino.
Do ponto de vista económico, pretende-se traduzir os consumos energéticos em custos (custos ambientais) e incluir esta parcela nos custos de construção, permitindo analisar as implicações que estes consumos poderiam ter nos custos da execução de uma obra.
O estudo pretende, ainda, caracterizar e estudar duas variantes no projeto e verificar a sensibilidade do mesmo no que respeita à energia incorporada, emissões de CO2, custo ambiental e custo de construção. Deste modo, pretende-se avaliar o potencial de poupança energético, ambiental e económico, com as variantes propostas, que se podem, ou não, traduzir em soluções vantajosas neste tipo de projetos.
Abstract: The dissertation approaches the issue of environmental impacts caused by the use of materials in the construction industry, as these produce significant environmental alterations associated largely to human and constructive activities. In this perspective, this work approaches two of the parameters that influence the environmental impacts, the embodied energy in building materials, with respect to the consumption of energy resources and carbon dioxide emissions (CO2). The purpose of this study is to quantify the energy requirements and CO2emissions, of a project of a new building with maintenance of building facades. From an economic standpoint, intended is the to convert the energy consumption in costs (environmental costs) and include this portion on the construction of costs, allowing to analyze the implications that these consumption could have on construction costs of a building. The study also seeks to characterize and study two variants in the design and verify its sensitivity regarding to embodied energy, CO2 emissions, environmental cost and construction cost. Thus, we intend to evaluate the saving potential for energy, environmental and economic, with the variants proposed, which may, or may not,translate into viable solutions in this type of projects.
