Model-based Elaboration of a Requirements and Design Pattern Catalogue for Sustainable Systems

Designing sustainable systems involves complex interactions between environmental resources, social impact/adoption, and financial costs/benefits. In a constrained world, achieving a balanced design across those dimensions has become challenging. However a number of strategies have emerged to tackle specific aspects such as preserving resources, improving the circularity in product lifecycles and ensuring global fairness. This paper explores how to capture constitutive elements of those strategies using a modelling approach based on a reference sustainability meta-model and pattern template. After proposing an extension to the meta-modelling to enable the structuring of a pattern catalogue, we highlight how it can be populated on two case studies respectively covering fairness and circularity.
