Abstract
Wood-based building materials are environmentally advantageous because of their lower greenhouse gas (GHG) emissions during manufacturing and capability of storing carbon permanently in their structure. The use of these materials can contribute for reaching the construction industry 2030 international goal of having carbon neutral buildings. Using carbon uptake estimation models, for these materials, improves the accuracy of GHG emissions quantification by construction industry and promotes the forestry sector. In this paper, the amount of carbon stored in wood materials is compared to amount emitted by the construction of residential apartments using traditional materials in Brazil. A sample of five apartments, representative of Brazilian typical construction scenarios, was analyzed, and the amount of carbon stored in wood products (such as doors, floors and ceiling linings) calculated. The impact of stored carbon n CO2eq (carbon dioxide equivalent) emission figures was assessed. The study shows that the stored carbon accounts, on average, for approximately 10% of the total CO2eq emitted during the construction.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
