Design Optimisation via BIM Supported Material Passports

Abstract

Scarceness of resources, lack of waste sites, dependency on imports, increasing urbanization thus increasing consumption of resources and upcoming of waste are current challenges in built environment. Reduction of both, energy and resources consumption, should thereby be the primary aims for sustainable design. Even though by 2020 70% of the building waste has to be either recycled or reused, resources efficiency is less considered than energy efficiency in the design stage of buildings. Previous research has shown, that the generation of Building Information Modelling (BIM)-based Material Passports (MP) is possible and can for example be used for optimization in early design stages. In the current curricula the energy design is well represented in the courses of building science, however, optimization of resource efficiency and recycling potentials are still lacking. The focus of this proposal is the implementation of the developed BIM-based Material Passports in teaching for optimization of design proposals, thus enhancing the awareness for recyclability and reusability in construction among students of architecture and civil engineering.
