ExpectedOutcome:

Project results are expected to contribute to all of the following expected outcomes:

• Reduction of on-site construction activities to 1-2 days per dwelling/building unit.
• Cost reduction of at least 25% compared to conventional renovation processes.
• Significant reduction of dust, noise and waste on the construction site compared to conventional renovation processes.
• Significant reduction in occupant disturbance during the renovation.
• Improved levels of occupancy comfort (e.g. Indoor Air Quality and Indoor Environmental Quality) after renovation.
• Reduction of negative impacts of renovation on biodiversity, considering adaptability as well (e.g. to climate change, different use, evolving societal needs, etc.) and resilience of buildings to disruptive events.

Scope:

Low-disruptive renovation processes, using prefabricated modules that are quick and easy to apply can play an important role in increasing the renovation rate of the European building stock. Renovation processes should cover the whole workflow from design to offsite manufacture, installation, compliance checking on site and end strategies for maintenance, operation and end of life.

Proposals are expected to address all of the following:

• Develop streamlined processes for deep energy-efficient renovation to at least NZEB performance levels using prefabricated modules.
• Use relevant available technologies to reduce quality gaps between the off-site manufacturing and on-site deployment of prefabricated modules.
• Develop processes for seamless integration of prefabricated solutions into a variety of existing constructions (e.g. various existing wall materials, presence of balconies and overhangs, existing piping in the way etc.).
• Ensure the processes minimize the disturbance for building owners, tenants and users, through a considerable time reduction of on-site construction activities, reduced impact in terms of the unavailability of the building and its main functionalities, and a minimal impact on occupancy comfort during the renovation process.
• Include at least three demonstrations covering different building categories (residential or tertiary) and various building typologies, such as single or multi-storey, single or multi-use, etc.
• Demonstrate less-disruptive retrofitting processes that are more attractive and more cost-effective for building owners, tenants and users.

Specific Topic Conditions:

Activities are expected to achieve TRL 6-8 by the end of the project – see General Annex B.
