There’s no doubt that construction of buildings and cities are activities with important social, economic, and environmental effects. This important activity consumes huge amounts of energy and resources and generates significant amounts of emissions and waste throughout its life cycle [1]. In fact, the sector of building construction is responsible for significant environmental impacts. According to some studies, around 20% of the total impacts are related to manufacturing, construction, demolition processes and final disposal of building materials, elements and systems [2]. Furthermore, authorities and public instances such the European Commission encourage the research of more sustainable building materials. According to recent studies, the manufacturing and construction of building structural elements (like, for example, columns, beams and walls) represent the largest proportion of embodied impacts. Some of these reports highlight the need to review of the materials and techniques we use today in order to make the building sector more sustainable [3]. The present work is the result of the investigation about new material options for the construction of structural load bearing walls developed by researchers from the University of Seville. The study is carried out to clarify the environmental performance of each assessed alternative. Some conventional and new materials based – especially those with low level of embodied energy; e.g. some composites materials such as earth blocks stabilized with natural fibers and alginates - are evaluated from the point of view their environmental consequences. |
