Analisi del ciclo di vita di un edificio residenziale in balle di paglia e confronto con tecnologie convenzionali

The work aims to assess the environmental impact of buildings with alternative ecological materials in comparison to conventional buildings. The study uses the case study of a single-family house located in the province of Bologna, built with a wooden supporting frame and straw insulation. To this end, an LCA survey was conducted to compare the technical solutions adopted with alternatives that use a reinforced concrete frame with brick infill and rock wool or EPS insulation and, finally, with infill and horizontal elements in autoclaved aerated concrete. The results of this study, dealt with using the One Click LCA software with the related databases and the European standard UNI EN 15978, indicate, in addition to an excellent energy behavior in the use phase of the built building, also a lower environmental impact, linked to almost all impact categories, compared to the alternatives. To evaluate the thermo-hygrometric behavior of the building and the correspondence between the energy performance data provided by the designers and the built reality, on-site analyzes were conducted.
