Estudo do uso da madeira e sua relação com a sustentabilidade no setor da construção civil
Notice bibliographique
Résumé
The planet Earth, throughout its period of existence, faces the consequences generated by climate change and the deterioration of the environment daily. Studies show that this aggravation can be caused by human activities, such as the deforestation of forests, which in the vast majority comes from anthropic actions in the livestock sector, agriculture and illegal extraction of wood, such actions produce significant emissions of greenhouse gases, boosting global warming. To contain these emissions, it is necessary to include activities such as reforestation and forest management, as they carry out the carbon sequestration, to reduce its concentration in the atmosphere. One of the sectores that exerts great influence on the quality of the environment is civil construction, throughout its construction process, from the beginning of the extraction of raw materials to its destination. One of the materials present in this market is wood, although little used in masonry for sealing buildings in Brazil, it has been present in society since ancient times, in the construction of shelters at the time for protection from the bad weather and in the manufacture of boats. Wood has numerous benefits, including its ability to promote significant reductions in greenhouse gas emissions, through the absorption of carbon dioxide produced in the process of photosynthesis for tree growth. When compared to other conventional materials most used in construction, such as steel, wood stands out and proves to be a sustainable material with great constructive potential. The extraction of this raw material must be carried out through controlled forest management, concomitant with the obtaining certification, and this certification is necessary for both parties, so that the consumer is aware of the origin of the management and for the environment which will be an explored in a correct way, assuring its preservation. In addition to the positive impact that the use of wood brings to a sustainable environment development, there is also economic development, through the carbon credit market, which includes projects aimed at reducing global emissions, contributing significantly to the country's revenue. Given this scenario, it is visible in many countries worldwide, such as Norway and Canada, the incentive and use of wood as a constructive raw material, on the other hand, here in Brazil, there is still the thought that this material is inferior to other traditional materials. Therefore, there is a need for a change of mentality both in society and the construction industry, so that there is an increasing application and evolution of the use of wood in the construction of buildings within the Brazilian construction market.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
