Meaning and importance
Architect Thomas Rau’s statement ‘Waste is material without identity’ shows how crucial information is if we want to move towards a circular economy. Making this information available digitally and managing it will be decisive in being able to bring materials, products or buildings back into circulation. The materials and/or building passport can help with this. In the absence of a prescriptive European framework, the sector is currently adopting a wait-and-see attitude. Therefore, there is a need for pioneers who gain experience in the practical implementation of construction passports, so that a prescriptive framework can be developed on the basis of this experience. This can range from a simple Excel file that lists all materials used to a ‘digital twin’, including disassembly plans and technical info sheets.
But information during the use phase can also help in the efficient use and management of a building. For example, smart building management systems can be used for maintenance management, energy and water consumption monitoring, the organisation of intensive use of space, etc. With the help of information and data management, this will allow us to save material and energy.
