1195 Transformation and acceleration of the construction supply chain through smart factories
Keywords:smart factory, renovation cycle time, supply chain
The European building stock is in high need of refurbishment due to its contribution to excessive global energy consumption. In the North-Sea Region (NSR) alone there are 22 million houses built between 1950 and 1985 with an annual CO2 emission of 79 Mton. Current deep retrofits are carried out on a limited-scale production, which may result in climate targets not being met in time. To tackle the need for rapid renovations, prefabricated insulation elements with integrated intelligent technologies, manufactured in novel smart factories using mass customization, could offer a solution. This approach is also followed by the Interreg project INDU-ZERO. The project examines a far-reaching automated production and develops a blueprint for a smart construction factory in the NSR that can produce 15 000 renovation packages per year. This paper aims to quantify the acceleration potential of the supply chain by improving its production, logistics, and on-site mounting processes for Dutch single-family terraced houses. First, the design of the renovation packages and smart construction factories are introduced. Then, the procedure is elaborated on how the supply chain can be abbreviated. The results show that the renovation cycle time can be completed within two weeks through coordinated efforts between production, logistics, and mounting.
