Multiparametric analysis of three construction systems considering sustainability indicators: environmental, economic and energy-functional

Abstract

The present study shows a multiparametric analysis of three construction systems made of partitions and concrete block. The analysis was carried out considering as a functional unit a square meter of construction wall for each partition and block, and including sustainability indicators: (a) environmental, through the Life Cycle Analysis (LCA), evaluating impact categories such as warming global, acidification and eutrophication (b) economic, estimating the cost of raw materials and construction cost for the functional unit and (c) energy-functional, through the mechanical resistance, thermal resistivity and acoustic resistance of the analyzed construction materials. A thermal simulation was also carried out with the bricks studied. The resulting analysis is a comparative tool that shows the differences between the studied materials and represents a methodology for decision-making based on the importance of each of the proposed indicators.
