“…In other cases, research is done by means of a LCA theoretical study through a literature review [22,[38][39][40][41]. Moreover, other researchers limit the LCA applicable results to a specific climate area [42] or a specific regulatory environment [40].…”

a b s t r a c tAccording to recent studies, the manufacturing and construction of the structural elements of buildings (for example, columns, beams and load-bearing walls) represent the largest proportion of embodied impacts. Some of these reports highlight the need to analyse the materials and techniques used today in order to make the building sector more sustainable. This paper presents the results of embodied energy and global warming potential, using life cycle assessment (LCA) methodology, for load-bearing walls, being these one of the most common types of structures for buildings. This study analyses through an eco-design tool new options for materials used in the construction of structural load-bearing walls. The research aims to examine the environmental performance of each material alternative assessed: fired clay brick masonry (FC), concrete block masonry (CB), reinforced concrete-based wall (RC), and stabilized soil block masonry (SS); stabilized with natural fibers and alginates. These conventional and new materialsespecially those with a low level of embodied energy, such as earth blocks -are evaluated from the point of view of their environmental consequences.

“…Wiessenberger et al [5] demonstrated the growing interest in LCA of building by the increasing number of publications of scientific studies in the last 20 years. Cabeza et al [6] review, also demonstrated the use of LCA in the building sector through the organization of a large number of literature that includes construction products, systems, buildings, and civil engineering constructions.…”

Life Cycle Assessment (LCA) is globally recognized as one of the most complete methods for environmental assessment of buildings. Literature assumes that its applications in the building sector are prejudiced regarding complexity and difficulty. However, simplification is necessary, since it can facilitate LCA application in buildings. Moreover, growing interest on reducing environmental impact in the building sector, as well as the relevance of single-family houses on CO2 emissions have become key points on the wide spread of LCA.Therefore, this paper presents a research study about simplification in LCA recent studies applied to singlefamily houses. The review focuses on 20 cases that were analyzed according to ISO 14040, ISO 14044, EN 15978, and EN 15804 standards. The main objective was to identify the simplification strategies assumed in each paper, to clarify and to help to promote further developments on LCA. This paper examines system boundary definition, data sources, life cycle phases included, and environmental impact indicator calculated in case studies. Results show the variety of simplifications identified. They affect physical model definition, life cycle scenario definition and communication of results. In most cases, the functional unit was the complete building, the life cycle scenario definition included production, use and demolition phases, and the most considered environmental impact indicator was GWP. Finally, new challenges and recommendations were defined in order to establish common criteria to develop simplification strategies that allow results comparability in LCA of single-family houses.

“…More precisely, in the general framework of climate change, the re-cast Energy Performance of Buildings Directive (EPBD) requires that from 2019 onwards "all the new buildings occupied and owned by public authorities are nearly zero-energy buildings" (nZEB) and by the end of 2020 "all new buildings are nearly zero-energy buildings" [6][7][8][9][10][11]. In other words, this European Directive on energy efficiency of buildings (EPBD) requires member states to ensure that on 1st January 2021, all new buildings have an energy "almost zero" consumption in order to obtain the nZEB label [12,13]. The aim of this directive is to enhance interdisciplinary research on building applications sharing knowledge about products, systems, conceptual methods and innovative techniques that combine low energy consumption, renewable energy and industrialization [14][15][16][17][18][19][20][21].…”
