Digital Solutions for a Circular Facade Economy

By Abhishek Holla

To progress towards going completely Circular by the year 2050, VMRG, a Dutch Metal Facade Association, has initiated several pilot projects. These include business models implemented with digital technology such as material passports(Cirlinq) and predictive maintenance using photogrammetry(FaSa). My research proposed a framework to integrate them to determine the re-life option with the higest value at the Facade’s End of Service(EoS).

This multi-disciplinary research tackles this with generating a framework using surveys and interviews with stakeholders in the supply chain of a Facade. The framework was then demonstrated using mock wireframe of the platform using data from the CiTG East Facade in the TU Delft campus. The research proposal includes 1. A data collection framework 2. Data structure 3. Data Templates Per stakeholder 4.Schematic wireframes of the digital platforms.

The research that was conducted represents the first steps towards a Digital Twin of the Facade’s Supply chain concluded in the form of recommendations to the Dutch Metal Facade industry.
