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 Countries and covering different building categories (residential or non-residential). 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 contribute to the objectives of Built4People, transfer knowledge to its network of innovation clusters^[1] and report on results in support of the monitoring of the Built4People KPIs.
