Results in brief

Acoustic and Thermal Retrofit of Office Building Stock in EU

The main objective of ActaReBuild is to train Doctoral Candidates in retrofitting Europe’s office building stock using a new generation of sustainable materials and components to improve and guarantee acoustic and thermal performance during renovation processes while minimising embodied carbon emissions. Through interdisciplinary training, ActaReBuild combines engineering, environmental science, and social considerations to address urgent needs for sustainable, comfortable, and energy-efficient building retrofits. Research focuses on developing novel mycelium bio-composites, composite materials using recycled plastics, and bio-based materials with customisable acoustic & thermal properties towards improved acoustic solutions and thermal energy storage. The project explores unique applications of metamaterials in buildings for improved airborne sound insulation of lightweight constructions at low frequencies and includes advanced measurement techniques for remote in situ sound absorption determination of ETFE-based building façades. ActaReBuild takes steps towards the proposal of better descriptors for airborne sound insulations of building façades, addressing not only spectral but also temporal features of noise in its perceived loudness and annoyance. Investigating the relationship between airtightness and acoustic performance in retrofitting processes addresses the challenge of energy efficiency vs indoor air quality and acoustic comfort. Finally, biotic materials for reducing embodied carbon in curtain façades are investigated, all adhering to circular economy principles, and transparent ultralightweight materials are examined for energy-efficient façade retrofitting to minimise environmental impact while maintaining structural integrity. ActaReBuild fosters solutions that balance historic and modern building retrofit challenges with sustainability goals, preparing DCs to lead advancements in building technologies that enhance comfort, reduce carbon emissions, and promote sustainable practices across EU.

Project objective

The objective of ActaReBuild is to provide high-level training of Doctoral Candidates in retrofit of office building stock in Europe by means a new generation of sustainable materials and building components. In particular, they will learn how to improve and guarantee acoustic and thermal performance of buildings that undergo renovation processes, while minimizing the embodied carbon production. The training offered to 10 Doctoral Candidates (DCs) interconnected through the network will enforce their research and transferable skills necessary for thriving careers in this burgeoning area. This goal will be achieved by a unique, interdisciplinary combination of specialized “hands-on” research training supported by high quality joint PhD degree supervision; by performing of secondments at industrial partners; participation at courses and workshops on scientific and complementary “soft” skills facilitated by the academic and non-academic partners of the consortium.Thanks to network-wide interactions, DCs will get acquainted with a variety of novel building materials and solutions (bio-, nano-, meta-, recycled, 3D printed materials and multilayer structural skins), measurement techniques and assessment methods (such as life cycle analysis and sustainability assessment, psychoacoustic methods, specialized thermal behaviour experiments and a variety of simulation techniques in acoustics, energy, hygrothermal behaviour). Their interaction with industrial partners within the consortium and, via outreach activities, to stakeholders in industry and society in general will promote the uptake of the resulting innovations beyond the network and accelerate their implementation for sustainable retrofits, thus maximizing the impact of the project.
