If you are a contractor dealing with inefficient mid-century masonry buildings — this project developed a self-supporting cladding and roof kit that allows for quick assembly without scaffolding. This reduces labor time and can cut primary energy consumption by about 90%.
Circular Energy Retrofit Kit for Mid-20th Century Multi-Storey Buildings
Imagine giving an old building a high-tech 'skin' that works like a giant battery and thermos. It replaces old roofs and walls with recycled materials that generate electricity and keep the inside warm or cool. It's like upgrading an old car to an electric one, but for entire apartment blocks.
What needed solving
Older multi-storey buildings have poor energy performance and high carbon footprints. Traditional renovations are often too slow, expensive, and rely on non-sustainable materials.
What was built
A multi-technology renovation kit consisting of a hybrid PV-thermal roof, bio-based self-supporting façade panels, and a solar-assisted DC heat pump system. A cloud-based decision support system for energy management was also developed.
Who needs this
Who can put this to work
If you are a property owner dealing with high utility costs in older tertiary buildings — this project developed a hybrid PV-thermal roof and DC heat pump system. This integration can reduce operational CO2 emissions by about 90%.
If you are a manufacturer dealing with the shift toward circular economy regulations — this project developed a system using recycled and bio-based materials for building envelopes. This provides a validated use case for repurposed components in large-scale urban retrofits.
Quick answers
What is the estimated cost or price of the RE-SKIN system?
Based on available project data, specific pricing is not provided, but the project aims to improve the affordability of renovations.
Can this be scaled to a large number of buildings?
Yes, the target market includes approximately 1,000,000 residential and 500,000 public/tertiary buildings across Europe, covering about 1.4 billion m2 of floor area.
Who owns the IP and how is licensing handled?
Based on available project data, the project contributes to standardization and certification activities, but specific licensing terms are not listed.
How does the system integrate with existing building infrastructure?
The HVAC system uses smart-fancoils designed to connect directly to existing heating piping, and the façade panels house new wiring and earthquake sensors.
What is the timeline for deployment?
The project runs from 2023-01-01 to 2026-06-30, with demonstration phases involving four pilot sites for data validation.
Who built it
The consortium is heavily industry-weighted with 12 industrial partners (57% ratio), including 11 SMEs, suggesting a strong focus on commercial viability. With 21 partners across 10 European countries, the project has the geographic reach to validate the system across different climatic zones and regulatory environments.
