Nachhaltigkeitsbewertung stählerner Tragkonstruktionen Erneuerbarer Energien: Methodenentwicklung und Anwendungsbeispiele

The upcoming installation of renewables in Germany is already politically established. Especially under consideration of sustainability aspects, the structural systems of renewables are very important. Rating systems for sustainability exist only for buldings but not sufficient for application in structural engineering. For a sustainable energy supply sustainability aspects should be considered during design and execution of structures of renewables. This article addresses the development of methods for sustainability assessment of load carrying steel structures of renewables. The described method is applied exemplary for the environmental sustainabilty assessment of a steel digester of a biogas power plant. With the help of the sustainability rating system, different construction methods can be compared under consideration of sustainability aspects. Furthermore, the method can be utilized as a help for a decision in order to fulfill sustainability requirements.
