Edificações de baixo impacto ambiental em madeira para o clima quente e úmido

Abstract

In this master thesis, wood is assessed as an alternative to reduce the negative impact of the construction of buildings in hot and humid climate. A multi criteria method is developed to assess the potentials and restrictions of wood systems, in order to support architectural design decisions. The research is based on four case studies, including three buildings in use and one under construction. The case studies were selected considering the research theme, designs availability to comment theirs projects during interviews, and the availability of complementary data to recover design information since the programming phase. To analyze case studies, evaluation criteria were selected from bibliography review. These characteristics allowed identifying the obstacles in the wood system application, evaluating the design decisions on the development of the constructions and to support the most feasible alternative, both technically and economically. The results confirm that wood buildings in warm and humid climate are feasible, and recommendations are identified based on the most recurrent obstacles, such as the cost of the structure, timber quality (certified, reforested or tropical), transport issues (documentation, cost and time), environmental impact and cost/benefit relation.
