The most significant environmental impact caused by buildings is generated during their useful life due to the energy consumption for thermal conditioning. The addition of green elements to buildings is a common strategy used to improve the energy efficiency of buildings. In this study we worked together with the ABIO research group to help Intemper quantify the environmental impact of green roof materials by applying the Life Cycle Assessment (LCA) methodology.
The results identify the enormous environmental impact associated with the structure, the important contribution of the felt wick irrigation system and the extruded polystyrene thermal insulation. The identification of hot spots of the system has permitted an eco-design strategy that effectively reduces the impact associated with roof construction, optimizing the environmental performance.
