The overall aim of BUS-GoCircular is to address and overcome the challenges of the stimulation of demand for green energy skilled workforce, along with hands-on capacity building to increase the number of skilled workforce across the value chain. But which skills does the workforce need to possess? Based on the different circular strategies and interventions that are being applied in practice we can map which occupations are involved within the implementation of these interventions. Based on this work (WP2.1) we can start mapping the different skills that are required for these different interventions (WP2.2). A generic framework for Circular Economy interventions in the construction value chain and its first application has been developed for the BUS-GoCircular project. This framework is based on the eight Key Elements of the circular economy framework (tier 1). The result of this is a set of archetypical interventions that improve the energy performance of a building while applying circular key elements. The eight Key Elements consist of 25 more specific strategies (tier 2). For these 25 different circular strategy groups (tier 2), the professions, trades and roles that are involved with implementing each strategy have been mapped across five stages of the value chain: Plan, Procure, Construct, Operate, and End of Service Life. This serves as the basis to provide an overview of the different roles that are required to implement such a strategy, from factory operative, over material scout, to material engineers. The framework has then been applied to the circular strategies relating to multifunctional roofs, façades and interior elements, including strategies evolving around energy efficiency. This application has been validated through interviews with relevant external stakeholders and experts from across the BUS-GoCircular project consortium.
