Eco-balance of structural steel.

With the upcoming Construction Product Requirements (CPR) the new basic requirement of sustainable utilization of natural resources must also be obeyed by the harmonized European market for construction products. Buildings must be designed, constructed and dismantled accordingly. Furthermore it must be assured that the buildings, the materials and members they are made of can be recycled, that the building is durable and that only environmentally sound raw materials and products are employed.
Within this normative context eco-balancing of construction materials has a growing importance. Also for the sustainability assessment of buildings, e. g. according to the DGNB label, qualified eco-data of the employed construction materials are an important input. This paper describes the eco-balancing of construction materials in general and of structural steel in particular.
