Resumo(s)
O desenvolvimento sustentável é uma abordagem fundamentada no equilíbrio entre três dimensões, denominadas ambiental, social e económica, visando a satisfação de necessidades, sem comprometer as das populações futuras. Aplicada na construção civil, a sustentabilidade tem por intuito assegurar que nos processos de execução, reabilitação e demolição sejam utilizadas estratégias que diminuam os impactos ambientais, promovam a viabilidade económica e proporcionem qualidade de vida para as gerações. Perante essa permissa, o objetivo do estudo é realizar uma análise comparativa entre soluções construtivas que sejam detentoras de pressupostos de maior sustentabilidade e que atendam os requisitos mínimos de comportamento térmico, com o fim de procurar soluções viáveis que promovam menor impacto ambiental, que atendam as reduções de energia e de água incorporada e que contribuam para a redução de emissões de GEE.
As opções construtivas selecionadas e alvo de estudo, foram analisadas a partir dos resultados coletados de diferentes categorias de impacto ambiental, tais como: GWP, ODP, AP, entre outros. Estudos bibliográficos foram realizados para sustentar a análise, além da consulta das DAP utilizadas em produtos de construção aplicados nas diferentes soluções estudadas. Os resultados baseiam-se numa proposta de solução para a reabilitação de uma edificação, que pode ser substituída por processos construtivos sustentáveis e termicamente eficientes, que são passíveis de aplicação.
Sustainable development is an approach grounded in the balance among three dimensions, namely environmental, social, and economic, aiming at satisfying current needs without compromising those of future generations. In the construction industry, sustainability seeks to ensure that processes of construction, rehabilitation, and demolition employ strategies that reduce environmental impacts, promote economic viability, and enhance the quality of life for generations to come. With this premise in mind, the study's objective is to conduct a comparative analysis of construction solutions that embody greater sustainability principles and meet minimum requirements for thermal performance. The goal is to identify viable solutions that minimize environmental impact, achieve energy and embodied water reductions and contribute to the reduction of greenhouse gas emissions. The selected construction options under study were analysed based on collected results from various environmental impact categories, such as GWP, ODP, AP, among others. Bibliographic studies were conducted to support the analysis, in addition to consulting the EPDs used in construction products applied in the different studied solutions. The results are based on a proposed solution for the rehabilitation of a building, suggesting the replacement of conventional processes with sustainable and thermally efficient construction methods that are applicable.
