Abstract(s)
A utilização dos recursos do planeta de forma a garantir a sua durabilidade é uma
necessidade que se faz presente em todos os setores da economia. Na construção civil, os
profissionais tem o papel de garantir a qualidade de vida das pessoas que frequentam os
espaços derivados de seus projetos, de forma a aliar as suas atividades à sustentabilidade
da sociedade e dos recursos naturais. Assim sendo, este trabalho pretende avaliar o
desempenho de uma habitação em aço leve levando em consideração a sustentabilidade
e a eficiência energética. Para isso, estudaram-se as ferramentas de certificação ambiental
que medem o nível de sustentabilidade em edifícios, bem como as propriedades
apresentadas pelo aço leve, possibilitando identificar as potencialidades e deficiências do
sistema construtivo em relação à temática da sustentabilidade. O caso de estudo abordado
para verificar o comportamento teórico do sistema construtivo consiste em uma
residência que será edificada na cidade de Bragança, Portugal. Trata-se de um edifício
cujo projeto arquitetónico foi realizado tendo em consideração os parâmetros normativos
portugueses de eficiência energética. O presente estudo teve a finalidade de, partindo do
projeto, analisar os materiais de envolvente e detalhes construtivos a serem aplicados no
modelo. As simulações relativas ao comportamento energético, realizadas através do
software DesignBuilder® consideram configurações de paredes, piso e cobertura com
materiais isolantes, mais especificamente o poliestireno expandido (EPS) e a lã de rocha,
sendo aplicadas diversas composições com variações nas espessuras das camadas de
isolamento. Essas simulações buscaram definir a espessura ideal de isolamento para
atingir a melhor relação entre o desempenho e consumo de materiais. Também foi
desenvolvido um levantamento considerando todos os parâmetros aplicados que
poderiam resultar em um melhor desempenho sustentável para a residência em questão.
The usage of natural resources seeking to ensure its durability is a remarkable need in all sectors of economy. In civil constructions, architects and engineers have the role of ensuring the quality of life of people who will occupy spaces originated from their projects, also combining their activities with sustainability of society and natural resources. This paper aims to evaluate the performance of a light steel framing building, regarding sustainability and energy efficiency. For this reason, green building rating tools were studied, as well as the properties presented by the light steel framing system, making it possible to identify the potentialities and shortcomings of the building system regarding sustainability. The case study consists of a single-family residence that will be built in Bragança, Portugal. In this case the architectural design was accomplished according the Portuguese law regarding buildings energy efficiency. Therefore, this study aims to study the envelope materials to apply in the model starting from the architectural project. Simulations performed using DesignBuilder™ software consider the walls, floor and roofing configurations with insulating materials, specifically expanded polystyrene (EPS) and rock wool, simulating compositions with variations in insulation thicknesses applied. These simulations intended to define the optimum thickness of insulating material to achieve the best ratio between the performance and consumption of building materials, predicting housing behavior in the post-occupation stage. A survey was also developed considering all the parameters applied that could lead to a better sustainable performance for this residence.
