IMPRESS leveraged the potential of prefabrication by developing a new range of easy to install panels, which reduced energy demand while preserving and/or improving building aesthetics.
Three prefabricated panels were developed, both for re-cladding and over-cladding, together with nano/micro particle based coatings, to achieve anti-corrosion and ageing resistance, improved solar reflectance and anti-vandalism properties. To produce the panels, an innovative manufacturing process was created that included Reconfigurable Moulding, 3D laser scanning and 3D printing technologies.
A new Iterative Design Methodology was developed, incorporating all stages of the Design-Construct-Install-Operate process, integrated with a cloud based BIM database. A Decision Support Software helped the end user to choose the most suitable renovation option.
Project demonstration sites
The project objectives were:
- Reducing primary energy consumption by 50%;
- Improving thermal performance and optimising light radiation by at least 30%;
- Improving precision of formworks for irregular shapes by 50%;
- Reducing installation time of prefab panels by more than 30%;
- Validate the performance of the prefabricated modules on the 2 demo sites over at least 12 month;
- Allowing for an RoI of < 10 years.
The results were demonstrated on two buildings where the final as-built product performance was validated against the initial design.
