Low disturbance prefabrication approaches for deep renovation of multi-storey buildings (Built4People Partnership)

Expected Outcome:Project results are expected to contribute to all of the following expected outcomes:Measurable reduction in the costs of deep renovation compared to current best practices;Measurable increase in resource and energy efficiency compared to current best practices;Measurable reduction in the number of days when occupants are disturbed due to renovation works;Measurable reduction of dust, noise, waste and pollutant and greenhouse emissions on the construction site compared to current best practices. Scope:Meeting Europe’s ambition for the renovation of the housing stock requires innovative approaches that improve buildings’ energy performance and occupants’ satisfaction, at a reduced cost while speeding up the renovation process and minimising impact on the construction site and disturbance for occupants. Renovation approaches should cover the whole workflow from design, off-site manufacturing and on-site installation to strategies for maintenance, operation and end of life.Proposals are expected to address all of the following:Demonstrate cost-effective approaches (comprising design, planning and construction processes and techniques) for deep renovation to at least NZEB performance levels of multi-storey buildings (> 5-storeys);Ensure that the approaches make use of prefabricated solutions that are adaptable and can be seamlessly integrated into a variety of existing building elements and features (e.g. various existing wall materials, presence of balconies and overhangs, existing piping in the way, etc.);Ensure that the approaches minimise the disturbance for building owners, tenants and users, notably through a significant time reduction of on-site construction activities and of unavailability of the building and its main functionalities, and a minimal impact on occupancy comfort during the renovation; Demonstrate the proposed approaches tailored to three multi-storey buildings (> 5-storeys), each in a different Member States or Associated Co
