SPHERE’s ultimate goal is the Improvement and optimisation of buildings’ energy design, construction, performance, and management, reducing construction costs and their environmental impact while increasing overall energy performance. SPHERE project will integrate two planes of research, innovation and improvement: • integration of the processes under the Digital Twin Concept involving not only the Design and Construction of the Building but including also the Manufacturing and the Operational phases • integrated platform that will be achieved through an underlying ICT Systems of Systems infrastructure based on Platform as a Service (PaaS) service to allow large scale data, information and knowledge integration and synchronization thus allowing a better handling and processing e.g BIMBots, machine learning , simulation etc. This Digital Twin concept is in fact a distributed but coordinated Database, including geometrical objects information that forms a unique synchronized virtual model of the reality. As has been proven in other fields, twinning this virtual information model with the reality helps significantly in decision-making during each phase of the whole building’s lifespan (manufacturing, design, construction, maintenance, operation, retrofitting and even demolition). The SPHERE cloud-ICT platform will allow to interact all different stakeholders during any phase of the asset with a building Digital Twin model of information of the building and a scalable set of different software tools, such as energy demand/performance simulation tools, Decision Support and Coaching Systems, BEMs or IoT enabled Predictive Maintenance Algorithms. The Digital Twin Concept, platform and Tools will be tested in four real pilots and finally validateted both technically and especially final social acceptance to accelerate market uptake.
