Dificuldades na implementação do design builder no mercado brasileiro
ABSTRACT: Os edifícios são grandes consumidores de energia, representando cerca de 40% do consumo no Brasil. Esta realidade deve-se frequentemente à má concepção projetual, que ignora sistemas e equipamentos que trazem economia de energia e o correto dimensionamento das cargas térmicas. Quando analisados usos comercial e serviço, com 15,4% e 8.0% respectivamente, a iluminação e o condicionamento de ar […]
Life cycle energy (LCEA) and carbon dioxide emissions (LCCO2A) assessment of roofing systems: conventional system and green roof
ABSTRACT: With the increase of urban occupation and therefore the constant need of new buildings, the concern about its environmental impacts grows recently. Thus, is demanded the research on the concept of buildings considering the economy of resources, especially energy. Green roof is an ancient alternative to reduce the effects of heat islands and global warming, providing architectural, construction, […]
Study of double windows efficiency in order to improve sound insulation in buildings
ABSTRACT: The aim of this research is to evaluate sound insulation behavior of double windows, when a second window is placed upon a previous one, keeping an air layer between them. This was done through standard tests carried out at the insulation chamber of the Acoustics Laboratory of Federal University of Santa Maria in accordance with international norms ISO […]
Normative references and instruments for flexible housing design in Brazil
