Viabilidade do sistema construtivo Wood Frame para habitações de interesse social em comparação ao sistema convencional.

Abstract

The adoption of more productive, durable construction systems, which are less aggressive to the environment and which have a competitive cost compared to the conventional system, is a reality that has been, little by little, gaining more space in Brazil. The conventional system, now widely used throughout the country, is a mostly artisanal system, characterized by low productivity, large waste of materials and consequent generation of large volumes of solid waste. As an alternative, the Wood Frame constructive method presents itself as an industrialized system, whose use is uncommon in Brazil, which may be related to the prejudice about the use of wood as a building material. Thus, this work proposed to analyze the advantages of this system in relation to the traditional one, through comparative analysis, carried out from bibliographic studies, through which qualitative and/or quantitative data were collected for parameters such as construction cost, comfort thermoacoustic, sustainability and environmental aspects, fire resistance, maintenance and architectural flexibility. For each of the parameters, grades and weights were assigned, and then a feasibility value was calculated, given by a mathematical equation, which served as a general parameter for comparison. Thus, it was possible to conclude that this method, even though it is still not very popular, has certain advantages over the conventional one, especially in terms of sustainability, thermo-acoustic comfort and ease of maintenance, and that, in general, it is a system that has potential for application in housing of social interest.
