In the quest to decarbonize the built environment, researchers are turning to modular construction solutions, and a recent study published in the ‘Journal of Sustainable Construction Materials and Technologies’ (or, in English, the ‘Journal of Sustainable Building Materials and Technologies’) is shedding light on the potential of these systems in deep energy retrofits. The research, led by Patrick Daly from the School of Architecture and Built Environment at the Technical University of Dublin, Ireland, explores the feasibility and challenges of applying a modular, circular over-clad system to social housing.
The European Union has set ambitious targets for decarbonization and circularity in the built environment, with a particular focus on large-scale renovation of the building stock. Modular construction is seen as a promising pathway to achieve these goals, but implementing such strategies in a complex and heterogeneous sector presents significant challenges. Daly’s research aims to address these issues by examining the potential of a modular over-clad system that incorporates advanced circularity and design for disassembly principles.
The study is based on a grounded case study methodology, utilizing mixed qualitative and quantitative methods to provide a detailed insight into the potential application, benefits, complexity, and challenges of delivering modular circular retrofit solutions. The results show that conventional modular systems can be adapted to function as over-clad retrofit solutions and incorporate advanced circularity principles. However, key issues such as stock non-homogeneity and diversity of host contexts, constructions, materials, finishes, and dimensional variations must be addressed.
“Our research demonstrates that modular circular retrofit solutions can offer high-quality, rapid installation options for deep energy retrofits,” said Daly. “However, the complexity and heterogeneity of the existing building stock present significant challenges that must be overcome to realize the full potential of these systems.”
The commercial impacts of this research are substantial for the energy sector. As governments and businesses increasingly prioritize sustainability and decarbonization, the demand for efficient and effective retrofit solutions is expected to grow. Modular circular systems offer a promising avenue for meeting this demand, providing rapid installation and advanced circularity that can significantly reduce the carbon footprint of the built environment.
Moreover, the research highlights the need for further innovation and adaptation in modular construction to address the diverse and complex nature of the existing building stock. As Daly notes, “The key to unlocking the full potential of modular circular retrofit solutions lies in our ability to adapt and innovate in response to the unique challenges presented by each retrofit project.”
In conclusion, Daly’s research provides valuable insights into the potential and challenges of modular circular retrofit solutions in the deep energy retrofit of social housing. As the energy sector continues to prioritize sustainability and decarbonization, the findings of this study offer a compelling case for the adoption of modular circular systems in retrofit projects. The journey towards a decarbonized built environment is complex and challenging, but with continued innovation and adaptation, the potential rewards are substantial.
