Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: Streamlining resource-efficient nearly zero-energy performance renovation processes. Renovations with reduction of at least 30 % waste, 25% cost, and 30% work time (to 1-2 days per dwelling/buildi...
ng unit), compared to current deep renovation processes. Reduced energy performance gap between as-built and as-designed (difference between theoretical and measured performance), and higher construction quality. Innovative, tailored business models for deep renovation, generating economies of scale and contributing to an increased rate of renovation. Improved comfort, Indoor Air Quality and Indoor Environmental Quality. Scope: In line with the Renovation Wave and in order to meet long-term climate and energy targets, more action is needed to increase the rate and depth of building renovation. Several recent projects and calls have focused on prefabrication for deep renovation, but more work is needed to develop innovative, seamless workflows from design to off-site prefabrication, to installation, construction on-site, maintenance and future dismantling, reuse and recycling of prefabricated elements, duly considering life cycle performance, sustainability, and the potential to use the buildings as carbon sinks. Proposals are expected to address all of the following: Investigate innovative approaches for industrialised deep circular renovation, covering the whole workflow from design through to off-site prefabrication, installation, construction on-site and strategies for maintenance, operation and end of life. Ensure the proposed approaches aim to achieve the highest level of energy performance (at least NZEB level) with a view toward zero-emission buildings, ensuring a high level of indoor environment quality, keeping costs in an attractive range for owners and investors. Make use of innovative processes and technologies, including those delivered by previous research, such as design based on circularity principles, prefabricated components, and digital tools that allow to optimise workflows (cost, time, quality, resource use). Demonstrate a seamless integration of the proposed approaches with state-of-the-art digital technologies for construction and renovation (Building Information Modelling, Digital Twins, etc.). Select processes and technologies that can be easily tailored to give a maximum potential for rapid and broad deployment at European level. Investigate innovative business models (e.g. as-a-service models), accounting for potential market and regulatory barriers, in view of mass deployment and Europe-wide impact. Apply the proposed workflows to at least three demonstrations to assess the proposed approaches for different buildings typologies representative of the European building stock, ensuring the most adequate coverage of the respective climatic conditions. The demonstrations can be either single buildings or clusters of buildings, and at least one of the demonstrations has to address residential buildings. Contribute to the activities of the Built4People partners and to the Built4People network of innovation clusters. This topic implements the co-programmed European Partnership on ‘People-centric sustainable built environment’ (Built4People). As such, projects resulting from this topic will be expected to report on results to the European Partnership ‘People-centric sustainable built environment’ (Built4People) in support of the monitoring of its KPIs.
