Resource-Efficient Design of Components for Office Buildings in Steel Composite Construction

The issue of sustainability is becoming increasingly important in all industries. Above all, the construction industry is affected by a high use of materials and a large amount of waste. Therefore, a large contribution to sustainability can be already made by a specific choice of designs and materials in the design phase of buildings. Within the scope of the German FOSTA research project P881 "Sustainable office buildings in steel composite construction" recommendations and planning tools for slabs and columns in consideration of structural and technical as well as economic and ecological requirements will be created. In this paper, the requirement profiles of floor systems are given. After an introduction to the environmental and economic performance, the possibilities of an environmentally compliant design for structural components are discussed. This includes the optimisation of static, ecological, and economical aspects. Furthermore, concepts for the increase of resource efficiency are demonstrated.
