RESUMO

This work carries out an energy consumption and CO IND. 2 emissions assessment on the production chain of three supplying systems for timber use in residential buildings: (1) timber obtained from the management of native forest; (2) timber obtained from the predatory extraction of native forest and (3) timber from eucalyptus plantations. The energetic sustainability on wood production is pointed out as a key criterion to classify timber as a sustainable material. Results demonstrate, through the reached potential on reducing energy demands, that native forest management is the most recommended system. Thus, the use of certified tropical timber is indicated as a measure of energy conservation on building construction as well as a strategy for the Amazonian Rain Forest conservation by the valuation of one of its main resources
