procuRE brings together 6 procurers from 6 countries, responsible for over 21,000 public buildings, to invest over €7 million in R&D to tackle their common challenge of achieving 100% Renewable Energy Supply (RES) in existing stock. Consortia bidding are expected to deliver a comprehensive package of tools enabling delivery across Europe and beyond of customised full-renewable building renovation. The systemic packages comprise services from design to implementation, and day-to-day operation, and contracting/financing, ensuring that the building continues to perform as designed over the full life-cycle. procuRE packages must ensure the following: enable optimal selection of cutting-edge components and configurations for RES generation, storage and management, fully addressing the challenges of on-site RES and eliminating off-site supply; increase SRI by integration across technologies and BEMS providing good occupant control; must deploy advanced BIM to model outcomes in advance in an assessment framework which at speed and low cost delivers procurers and investors with transparent choices of their options to maximise value delivery across the complete life-cycle; must provide simple configuration to match regulatory differences; and must include innovative, embedded and cost-efficient training services to impart necessary skills to both operators and to occupants, whose behaviour is a growing factor to be taken fully into account. PCP competitive tendering and the three phases of R&D and supplier selection is expected to ensure delivery of reasonably mature renewables renovation packages and their entry onto the international market within the expected timescale. Package efficacy will be demonstrated in the types of building which dominate public portfolios and promise replication in the private sector, in a multi-country public demonstration of solutions meeting building stock decarbonisation targets - six configurations achieving 100% RES throughout the year.
