In the context of climate change and energy crisis, issues relating to the energy balance and efficiency of buildings are particularly relevant. Through its economic, ecological and socio-cultural aspects, the preservation of historic buildings contributes directly to the sustainable use of resources and thus to climate protection. Historic buildings, which are predominantly made of durable materials and constructions, are a good example of green culture through energy-saving utilisation and further development in line with the existing building stock. The (grey) energy already used in the construction of old buildings does not have to be used again if careful and careful renovation is carried out, including the use of sustainable building materials.
Wood has always been a sustainable, resource- and energy-saving material and is one of the oldest building cultures in the world. In Germany alone, timber architecture (half-timbered houses, roof structures) is considered to be characteristic. It is therefore important to observe and understand the properties, condition and changes to this material, both in terms of the preservation of historical monuments and the future use of wood as a building material.
and to understand them. Promising technologies such as optical 3D measurement technology and AI-based data analysis are now available for this purpose, which have hardly been used in this sector to date.
The aim of this project is to develop a process for automated component documentation and monitoring of existing old timber construction. This includes
- Development of a prototype optical measuring system for inventory and feature recording;
- Development of an automation process for feature detection;
- Automation of the information transfer to a digital 3D model.
The following results are aimed for in the course of the project:
- Measuring method consisting of innovative hardware (RTI sensor, patented) and software (AI-supported feature recognition) for objective and documented strength analysis of used wood;
- Interface for the automatic transfer of timber parameters to a digital twin (based on BauWolke software/BauCAD);
- Future marketing opportunities through sensor/software and extended range of services by experts.
