In the quest for sustainable and resilient urban development, a novel framework developed by researchers at the University of Northern British Columbia is shedding light on the potential of modular construction. Led by Mohammad Kamali from the School of Engineering, the research published in the journal *Resilient Cities and Structures* (which translates to *Resilient Cities and Structures* in English) offers a comprehensive approach to evaluating the sustainability performance of modular homes, with significant implications for the construction and energy sectors.
The study introduces an integrated multi-level decision support framework designed to quantify and assess the sustainability benefits of modular construction. This framework is a response to the growing need for evidence-based practices in the construction industry, particularly as cities worldwide grapple with the challenges of rapid urbanization and climate change.
“Modular construction is increasingly seen as a viable alternative to conventional building methods,” Kamali explains. “However, to fully realize its potential, we need robust tools to evaluate its sustainability performance across various metrics.”
The research focuses on single-family residential modular homes, using criteria and indicators developed through extensive literature review and surveys. The framework employs multi-criteria decision analysis to provide a holistic assessment of sustainability, encompassing environmental and economic factors.
Two case studies conducted in the Okanagan region of Canada demonstrated that modular homes outperformed their conventional counterparts in multiple sustainability metrics. The modular homes achieved eco-efficiency values of 62.5 and 56.0, respectively, placing them in the higher performance range. These findings underscore the potential of modular construction to deliver more sustainable and resilient housing solutions.
The proposed framework offers flexibility in examining different dimensions of sustainability, providing valuable insights for stakeholders in the construction industry, municipalities, governments, and policymakers. By integrating life cycle thinking and decision-making, the research aims to inform the selection of suitable construction methods for future city developments.
“The framework we’ve developed can help guide decision-makers in choosing construction methods that not only meet current sustainability standards but also contribute to long-term resilience,” Kamali adds.
The implications for the energy sector are particularly noteworthy. Modular construction’s efficiency in resource use and reduced construction times can lead to lower energy consumption and reduced carbon footprints. As cities strive to meet ambitious sustainability goals, the adoption of modular construction methods could play a pivotal role in achieving energy efficiency targets.
This research highlights the importance of adopting innovative construction practices that align with sustainability and resilience objectives. By providing a robust tool for evaluating the performance of modular homes, Kamali and his team are paving the way for more informed decision-making in the construction industry. As urban areas continue to expand, the insights gained from this study could shape the future of sustainable urban development, offering a blueprint for building resilient and energy-efficient cities.
