Our study takes an environmental pe

Our study takes an environmental perspective when comparing various conventional technologies for building walls to others that use new low-impact materials. By identifying and quantifying the materials used in the manufacturing processes and applying LCA methodology, we identify the environmental impact of each building alternative studied. Summing up, our study identifies the processes involved in each technology, quantifies their associated impact and compares their environmental performance.The aim of this research is to compare the environmental aspects and potential impact associated with the construction,maintenance and disposal of walls in three-storey buildings, determining the option with the lowest negative impact in relation to mechanical and structural characteristics. A life cycle assessment was made of three models of housing blocks erected with load-bearing walls that varied according to their material structure.The options compared involved conventional and unconventional building materials, therefore, the study analysed:
•fired clay brick masonry (FC),
•concrete block masonry (CB),
•reinforced concrete-based wall (RC),
•stabilized soil block masonry (SS).
