CO 2 EMISSIONS IN OWN MATERIALS FROM VERNACULAR ARCHITECTURE
The development of materials in the construction industry has a direct impact on greenhouse gas emissions - GHG, throughout the entire construction process from production, use and reuse. Being able to evaluate the energy embedded in the entire process is essential to establish criteria that allow the corresponding emissions to be calculated. The environmental impact of the building can be reversed through the appropriate use of materials referenced in the vernacular architecture if aspects of the life cycle characterized by standardized and regulated data on CO 2 (Carbon dioxide) emissions are considered. This research has analyzed existing information on CO 2 emissions of natural or traditional materials based on standardized data contained in 266 EPD (Environmental Product Declaration). It is important to generate this type of information so that it can be implemented in official construction databases. Specifically, 815 materials have been analyzed, based on their environmental impact, and a comparison of data – emission values, according to vernacular and non-vernacular materials – has also been developed, identifying on the importance of the use of traditional materials in vernacular architecture.
