Title:
Abstract:	Die zunehmende Inanspruchnahme von Ressourcen und die damit einhergehenden Umweltauswirkungen rücken im Bauwesen immer weiter in Vordergrund. Derzeit sind die beiden Disziplinen für etwa 60 % des Ressourcenverbrauchs sowie für etwa 35 % des Energieverbrauchs verantwortlich [1, 2]. Dieser Anteil könnte noch steigen, wenn alle Bauten eine konventionelle Weise verlangen, da die Weltbevölkerung weiter zunimmt. Prognosen gehen von einem Anstieg der Weltbevölkerung bis 2100 von derzeit knapp 7,5 Milliarden auf etwa 11,2 Milliarden Menschen aus [3]. Um der wachsenden Weltbevölkerung sowie der großen Ressourceninanspruchnahme gerecht zu werden, sind innovative, ressourcensparende Leichtbaukonstruktionen unumgänglich. Aktuelle Forschungsarbeiten erweitern das Spektrum hin zu adaptiven Leichtbaukonstruktionen, die es erlauben, bauphysikalische Eigenschaften gezielt anzupassen, um letztlich den extensiven Baustoffeinsatz zu reduzieren. Zur Quantifizierung und Verifizierung der damit verbundenen Potenziale in puncto Nachhaltigkeit wurden die Einflüsse der Adaptivität von Leichtbaukonstruktionen auf deren bauphysikalisches Verhalten sowie deren Ökobilanz erfasst und beschrieben. Physical and environmental potentials of adaptive lightweight constructions The increasing use of resources and the associated environmental effects are becoming more and more important in architecture and construction. Currently, the two disciplines are responsible for about 60 % of resource consumption and about 35 % of energy consumption [1, 2]. This percentage may rise, if all men demand conventional buildings since the world population continues to increase. Forecasts predict an increase in the world population by 2100 from currently just under 7.5 billion to around 11.2 billion people [3]. Innovative, resource-saving lightweight constructions are indispensable in order to meet the growing world population and the large demand for resources. Latest research work extends the spectrum to adaptive lightweight constructions, which make it possible to manipulate building physical properties in a targeted manner. They are attributed with great potential in terms of their slimness, low mass and heat storage capacity, sustainability and the associated ecobalance. In order to be able to verify and quantify these potentials, the influences of the adaptivity of lightweight constructions on their structural-physical behaviour and their ecological balance were simulated and described for the first time.
