Apreensão de carbono em construções de madeira

Abstract

Global warming is already a reality, and the need to count it is more and more urgent, forests play an important role in removing carbon from the atmosphere, and retain it in large quantities in wood. When using this material (wood) for constructive purposes, the carbon remains stored, preventing it from being released into the atmosphere, in the form of CO2 and other gases. Within this context, the study aims to measure the impact that the intensive use of wood in civil construction would cause in the capture of carbon, aiming to mitigate emissions of greenhouse gases. To obtain the data, a literature search was carried out in order to verify the quantity of materials used in wooden constructions in the wood frame system. A 42 m² housing construction was selected, quantifying the wood that make up the structure of the house, the amount of carbon present in the wood and converting the carbon mass to carbon equivalent. Subsequently, scenarios were designed with a number of wooden houses that could be built in the country, based on data obtained from institutions linked to civil construction. One of the scenarios was based on the program my house my life and resulted in 12.4 million tons of carbon equivalent learned in a period of ten years, if 50% of the houses were built in wood. Another projected scenario suggests that 38 million tonnes of carbon equivalent could be seized in wooden constructions between 2017 and 2027.
