Potential for innovative massive building envelope systems – Scenario development towards integrated active systems
In order to generate possible scenarios about future developments of massive constructions, this paper explains the developmental paths on the basis of individual materials of clay/brick as well as concrete/lightweight concrete/aerated concrete and sand-lime brick. These construction types are organised qua development level on a roadmap, structured by a timeline and the division in massive and skeleton construction. By this development, lines of constructions appear, structured by the order of additional functionalities integrated in each development step. Following this path, possible scenarios for future developments of integrated active systems are sketched, following the line of additional functionalities being integrated in the construction. Drawbacks such as the limitation of recycling of integrated constructions and the conflict of insulation versus load bearing capacities are named. As a result two strategies are expressed: the light massive envelope construction with integral layers and the massive oriented solution with possible exchangeable components are developed and illustrated by five general construction principles.
