SR2 is the world’s first robotically 3D printed air diffusion system. It is a radical approach to how we deliver air in existing buildings to ensure they stay relevant. In Australia, 98% of all buildings are existing. Retaining and retrofitting our built stock is critical to mitigating climate change.

The construction industry contributes around 40% of global carbon emissions. As a society, we are facing significant challenges and can’t afford to continue building in the same way we do now. What is required is the far-reaching transformation of our current practices including new approaches to design, materials and construction. SR2 confronts these challenges head on, showing a path towards a decarbonised building culture.

Designed for circularity and disassembly, SR2 is 3D printed from recycled plastic waste. Making the switch to recycled plastics and designing out redundancy has allowed SR2 to reduce its embodied carbon footprint by 90% when compared to traditional steel duct work. At the end of its life, each component can be shredded, creating new material to 3D print a new component.

Inspired by nature and enabled by advanced manufacturing, SR2 is designed to branch and breathe like a natural organism, creating new opportunities for comfort and expression. Shaped for air, the system’s aerodynamic form reduces friction, leakage and energy consumption, resulting in a reduced size of each component. Thousands of tiny pores on its surface allow the system to ‘breathe’ through its skin and diffuse air into the space. Its plug and connect system enables building owners and tenants to easily adapt and reconfigure the layout to their changing needs.

SR2 is the result of a collaborative research project between BVN and the School of Architecture at the University of Technology Sydney (UTS). Our partnership demonstrates the transformative power of advanced technologies and the real-world impact of architectural practice that goes beyond traditional boundaries to address some of our most pressing environmental and societal challenges. We hope this research will inspire and motivate others to reconsider how we design and build the world we live in.
