2. Research aim and methods
Most part of the papers available in literature use LCA tool in case studies due to the need to fully define all the variables within the limits of the analysis [31–37]. In other cases, research is done by means of a LCA theoretical study through a literature review [22,38–41]. Moreover, other researchers limit the LCA applicable results to a specific climate area [42] or a specific regulatory environment [40]. And there are also models of analysis seeking to apply LCA tool to obtain improvements in the design of the processes of manufacturing and construction [43,44]. This study is not intended to reach the definition level of a given case study but to support designers’ environmental concerns establishing a first approximation using the parallelism between structural parameters and LCA of different materials commonly used in load-bearing walls.
