LCA Analysis of Three Types of Interior Partition Walls Used in Buildings

Abstract

Numerous studies have been done with the purpose of identify and try to reduce the impact generated by the construction industry, mainly focused on the use stage in the search to increase the energy efficiency. However, as these stage has been improved and the impact produced has been reduced, it has become evident the need to focus the research on the elements and life cycle stages that follow on the affectation scale. Therefore, the present research analyzes the importance of the embodied energy and the affectation generated by the materials with a LCA perspective, comparing one square meter of three different systems used as interior partition walls: hollow clay brick (HB), hollow concrete block (CB) and gypsum board (GB). The analyzed stages are from production of the materials to the building construction (stages A1–A5), using the Eco-invent database with the LCA manager software. The results of the analysis indicate the values of the environmental affectations and the consumptions made by each element during the analyzed stages. The comparison allowed to find that the constructive solution with mayor environmental affectation in the analyzed categories is the GB wall, and that is mostly done in the production stage (A1–A3).

“…Andere Veröffentlichungen fokussieren sich lediglich auf die Herstellungsphase (Module A1-A5). [10,11,5] Da die Vorgaben nach DIN 15804 für Bauwerksanalysen konzipiert sind, fanden im Rahmen dieser Untersuchung Anpassungen für eine bauteilorientierte Lebenszykluskostenbetrachtung der in Abschnitt 1 genannten Phasen statt. Die Nutzungsphase wird lediglich qualitativ bewertet.…”

“…The study also investigated whether employing AAC in building construction is economically feasible and whether it might affect energy use and greenhouse gas emissions. The LCA of three types of interior partition walls used in buildings-gypsum plasterboard, AAC blocks, and calcium silicate blocks-has been given by Valencia-Barba et al [17] and Ferrández-García et al [18]. The findings indicated that gypsum plasterboard has the most significant environmental impact, whereas AAC blocks have the lowest, especially regarding energy consumption and ability to cause global warming.…”
