This new factory building for Airbus is a model for sustainable factories of the future. It is an engine factory on the last plot of land on the Airbus campus. As designers, we framed our own ideas and the goals of the client in a data-driven framework in order to achieve a complex, multi-functional building beyond traditional approaches and beyond what a human alone or a computer alone could achieve. This building involves both large and small strategies to address embodied and operational impacts over the entire lifespan of the project. This includes attention to sourcing of innovative materials (like engineered timber trusses, bio-cement pavers, and carbon-capture concrete), use of natural lighting and ventilation (without air conditioning), and flexibility for the building to adapt over time as needs change. Through iterative use of Lifecycle Analysis and targeted selection of sustainable, durable, and reusable materials, we reduced carbon emissions by 48% compared to a typical factory. In addition to focusing on typical factors like productivity and cost, we focus on employee work conditions for both blue- and white-collar workers. Our process of generative design brings together multiple stakeholders for an inclusive discussion and debate about the most important features and aspirations of the project. Our design approach deliberately engages difficult decisions about the balance of cost and impact. It involves a framework for thinking about the most scalable version of sustainability with the greatest potential impact by weighing the trade-offs between different design features.
