Almost everything in construction costs too much, is too resource intensive and takes too long. The majority of buildings on the planet use steel ductwork for their air systems, even though it has remained largely unchanged for over 90 years. This costs the planet, the building owner and the occupants. When current global building stock is estimated at 223 billion square metres, and set to almost double to 415 billion square metres by 2050, the implications are significant. Systems Reef 2 is the world’s first 3D printed air diffusion system (patents pending). It is designed to replace steel ductwork and revolutionise the way we deliver air in new or existing buildings globally. Systems Reef 2 establishes a new circular category for building services using waste plastics, robotic 3D printing and Ai driven workflows. It’s cheaper, better for the planet and designed, manufactured and installed in a fraction of the time compared with traditional steel ductwork. It addresses issues of cost, productivity, resource intensity and lack of digitisation in the construction sector. SR2 has attracted worldwide coverage. It has been covered by Fast Company as a potential solution to ‘One of the office’s biggest problems’. It was nominated by Dezeen as one of the “Top 10 designs globally that rethink the way we use energy”. It also has been called “The Future of HVAC” by AIRAH – the Australian industry peak body for Refrigeration, Airconditioning and Heating. SR2 won the Innovation Award - New Green Product in the 2022 Australian Sustainability Awards and the Pioneer Winner of the Tomorrw Awards 2023.
