The ‘SWIMing’ project will support EeB projects to enhance the impact of their results by making their data models open and accessible. It will develop a data modelling cluster where projects can share their use cases, data modelling requirements and get access to expertise in the area of open data models. The cluster will be structured by stages of the building life cycle (BLC) the projects results are applied, its particular domain, and the differing data requirements. By making project outcomes open and accessible to multiple stakeholders across the BLC, SWIMing will impact on the ease and efficiency with which these outcomes will be exploited across BLC energy management processes.
