World Sustainability Forum 2014 – Conference Proceedings Paper Environmental Assessment Design Tool Specially Developed for Mechanical Engineering Students

Over the last two decades, environmental legislation has increased in Europe. Life Cycle Assessment allows researchers and engineers to measure the environmental impact of products, allowing them to reduce it and contribute to sustainable growing. The European Union has devoted several laws to introduce ecodesign measures in energy-using and energy-related products. However, although most industrial products (TVs, computers, cars...) are designed and developed by engineers, most of them have not received environmental training in their university studies. In order to teach environmental design concepts to mechanical engineering undergraduates, an environmental impact assessment tool has been created. In this paper the ECOCAD software is shown, as commercially LCA software is not prepared to be used by untrained users. ECOCAD allows students to easily analyze the influence of design decisions on the environmental impact of a component, allowing them to compare different materials (steel, aluminum, plastics... each one with different Young Modules and elastic admissible strains), calculating how the safety coefficient changes depending on the loading conditions. Also the environmental impact of manufacturing processes (stamping, plastic injection, thermoforming, die cast, extrusion....)
