Façade elements for hybrid construction methods – prefabricated, integral timber façade elements for use in newly constructed hybrid reinforced-concrete buildings
02/2014 - 09/2016
Supported with funds from the Bavarian construction industry
The objective of the project was to drive the development of prefabricated timber façade elements for highly insulated, energy-efficient and resource-efficient building envelopes, using building materials primarily from renewable raw materials, in combination with reinforced-concrete support structures.
The emphasis was on creating consistent links between these two construction methods each of which is highly advanced.
The project dealt with questions related to structural design, thermal insulation and moisture protection, as well as fire protection and sound insulation in the context of the shell construction, aiming to create economically optimized links between reinforced-concrete floors and walls and affixed or embedded timber elements. In addition, top quality and excellence in the execution of the construction works is one of the foundations of sustainable construction. To help reach climate protection goals, it is necessary to increase the energy and resource efficiency of new buildings, both in their production and operation, which mainly involves optimizing the components installed. The specification and determination of characteristic values, for example on the basis of life-cycle analyses (LCA) and recycling concepts for the components used, is another integral planning aspect, which will play an increasingly important role in future commissioning decisions and certification systems. In summary, the results were incorporated in a standardized design index that contains possible uses and combinations of timber façade elements applicable up to the height of non-high-rise buildings.
