Title:
Abstract:	Angesichts schrumpfender Ressourcen und der stetig zunehmenden Belastung unserer Umwelt durch Schadstoffe und zu deponierende Abfälle muss das Ziel im Bauwesen in einer erheblichen Neuorientierung der Konstruktionsweisen bestehen. Die gebaute Umwelt (Hochbau, Tiefbau, Infrastruktur) steht für ca. 35% des Energieverbrauchs, 35% der Emissionen, 50% des Ressourcenverbrauchs und - zumindest in Zentraleuropa - für mehr als 50% des Massenmüllaufkommens. Mittel- bis langfristig ist dies im Interesse einer nachhaltigen Bewahrung unserer Umwelt für die nach uns kommenden Generationen nicht mehr zu vertreten. Ziel muss sein, die permanente Entnahme von Rohstoffen aus der Natur stark zu reduzieren (langfristig auf Null) und gleichzeitig das Entstehen nicht anderweitig zu verwendenden Abfalls möglichst zu vermeiden. Ein recyclinggerechtes Konstruieren ist für das Erreichen dieser Ziele eine wichtige Voraussetzung. Ziel muss eine Kreislaufwirtschaft sein, bei der idealerweise nur die Ressourcen genutzt werden, die sich bereits vorher im Stoffkreislauf befanden. Um dies praktisch erreichen zu können, sind allerdings viele durchgreifende Veränderungen notwendig, die jetzt den entwerfenden und konstruierenden Ingenieur erreicht haben. Reduction of weight and embodied energy in Highrise construction The built environment (architectural engineering, civil engineering, infrastructure) stands for approx. 35% of the energy consumption, 35% of the emissions, 50% of the consumption of resources, and - that is to say in Central Europe - for more than 50% of the mass waste volume. In medium to long-term considerations about a sustainable preservation of the environment and for the benefit of the coming generations this view can no longer be hold. In the light of dwindling resources and of the steadily increasing pollution of the environment by pollutants and by waste to be landfilled the target must consist in a radical re-orientation - both with regard to the question, how we are building and with regard to the question, how we are using our built environment. We must succeed in drastically reducing the permanent withdrawal of natural resources from the nature (in the long term down to zero) and simultaneously in avoiding the development of non-reusable waste. At the same time it will be necessary to produce the entire energy required for the built environment on the regenerative way. A recyclable design is an indispensable precondition for reaching these goals. The aim must be a circular economy with ideal use of resources which were already before integrated in the material cycle. Indeed this can in fact be reached with radical changes only.
