Sažetak
The increasing population growth and urbanization rises the worldwide consumption of material
resources and energy demand. The challenges of the
future will be to provide sufficient resources and to minimize the continual amount of waste and energy demand.
For the achievement of sustainability, increasing recycling rates and reuse of materials, next to the reduction of
energy consumption has the highest priority.
This article presents the results of the multidisciplinary
research project SCI_BIM, which is conducted on an occupied existing building. Within SCI_BIM, a workflow for
coupling digital technologies for scanning and modeling of
buildings is developed. Laser scanning is used for capturing the geometry, and ground-penetrating radar is used for
assessing material composition. For the semi-automated
generation of an as-built BIM, algorithms are developed,
wherefore the Point-Cloud serves as a basis. The BIMmodel is used for energy modeling and analysis as well
as for the automated compilation of Material Passports.
Further, a gamification concept will be developed to motivate the buildings’ users to collect data. By applying the
gamification concept, the reduction of energy consumption
together with an automated update of the as-built BIM will
be tested. This article aims to analyze the complex interdisciplinary interactions, data, and model exchange processes
of various disciplines collaborating within SCI_BIM.
Results show that the developed methodology is confronted with many challenges. Nevertheless, it has the
potential to serve as a basis for the creation of secondary
raw materials cadaster and for the optimization of energy
consumption in existing buildings.
