Sustainability assessment for steel constructions of renewables

Sustainability assessment for steel constructions of renewables. The consideration of sustainability gets more important to society aspects. Sustainable systems that eliminate ecologic and economic effects on future generations are preferred. Especially in civil engineering this convention gains importance. Up-to-date established and approved assessment systems to evaluate and quantify the sustainability of constructions regard only buildings. With respect to the change of energy sources from fossil to renewable, the constructions for renewables should fulfil sustainable criteria. Therefore this article establishs a rating system regarding sustainability for steel structures of renewable energies. The approach as well as preliminary results considering ecological effects of offshore wind energy support structures are given. Indicators derived from the building sector are presented. Beside the wind energy, the focus is set to biogas plants.
