Abstract

The research aim is the study of the design issuesof the building envelope in the field of environmental sustainability, as well as closely related to the assessment and quantification of its impact with Life Cycle Assessment (LCA) methodology. In particular, the case study relates to the analysis of the variation of the environmental impacts of a residential, multi-family building in Putignano (Ba), in relation to the alternative use of two types of external vertical technologies, the first one made up by thermo blocks and EPS wall coating and asecond one, dry assembled. The interest in this variability arises from the potential consequences that these technologies generate on the environmental impact of the building, in relation to their different construction and demolition techniques, to materials/components used, their relative maintenance needs and the implications on energy consumption. The aim was, first, to identify, on the basis of the interdependence existing between the service life of technologies and of buildings(in relation to the final use), the technological solution characterized by the lowest impact but also to explore improvement strategies. For this purpose, it results interesting the study of the impacts differences generated by the two solutions with reference to the use phase. For each kind of technology, total impacts of the whole building were quantified, during several life cycles hypothesis (from 15 to 150 years): this has allowed to identify and test, through LCA, appropriate improvement solutionsspecific for each technology, based on the use of natural and local resources and on the strengthening of recycling and reuse strategies in the construction industry.
