Building information modelling adapted to efficient renovation (RIA) Proposals should develop advanced solutions, including all of the following: To harmonise and provide common data exchange formats regarding the components and equipment of a building (e.g. the type of materials and the Heating, Ventilation and Air Conditioning (HVAC) systems in relation to the most actual standards); The modelling of the building energy should include existing parameters, as well as the environmental and GIS data; Be flexible in coupling the overall BIM system with other additional types of models (e.g. buildings acoustics; including calculator for economic evaluation of various renovations scenarios); Be flexible to adapt to work planning, as-buildings documentation and procedures to process changes; Allow the development of applications to benefit from inputs of inhabitants; A close cooperation with standardisation bodies is required in order to validate the new BIM tools. Proposals submitted under this topic should include actions designed to facilitate cooperation with other projects; to enhance user involvement; and to ensure the accessibility and reusability of data produced in the course of the project.Activities should start at TRL 4 and achieve TRL 6 at the end of the project.The Commission considers that proposals requesting a contribution from the EU between EUR 5 and 7 million would allow this specific challenge to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requesting other amounts. The Building Information Modelling (BIM) tools developed so far are adapted mainly to new buildings (all types). In order to offer easy, practical, operational tools for all stakeholders, including constructing companies, designers, architects and service companies, we need to deploy attractive tool kits also for existing buildings. A particular important challenge will be to produce compatible tools that would allow collecting of data from existing buildings (e.g. geometric data) and exploit data from different sources. This will also contribute to more accurate knowledge of the existing building stock by providing methods and tools to generate data for existing buildings. Such BIM tools will be exploited first and foremost in existing residential buildings. Proposals should achieve all of the following: A reduction of the renovation working time of at least 15-20% compared to current practices with the baseline defined in the proposal; Acceleration of the market uptake across Europe, by speeding-up industrial exploitation, in particular amongst constructing/ renovations companies with a target of 50% of their renovation business based on BIM; Creation of best practice examples for the construction retrofitting sector with benefits for the operators and associated stakeholders (architects, designers, planners, etc.). Relevant indicators and metrics, with baseline values, should be clearly stated in the proposal.
