LeNSes is a 3 year project, involving 3 design schools in Europe and 4 in Africa. LeNSes is an action of human resources and curriculum development, aiming at the promotion of a new generation of designers (and design educators) capable to effectively contribute to the transition towards a sustainable energy for all society. LeNSes ambition is to promote a new shared and articulated disciplinary ground on System Design for Sustainable Energy for All (SD4SEA) focused on Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE) models, through a series of exchange activities and pilot courses at the partner institutions. LeNSes produces an open learning e-package, as modular package of teaching materials (texts, slide shows, audio, video, etc.) and tools for designers and design educators worldwide able to download (free of charge), modify/remix and reuse (copy left). LeNSes also promotes a series of diffusion activities targeting the design community worldwide.
