Comparison between building roof construction systems based on the LCA

Abstract Based on Life Cycle Assessment techniques, this research compares the environmental impact of 11 variants for the construction of roofs in residential buildings. Among others, the energy used, the carbon footprint and the waste associated to placement and packaging are found, leading to 9 s...
