Energy considerations constitute the main driving force behind new developments in the façade industry: the necessity of energy savings, insulation against heat and cold, energy storage measures as well as the alternatives for energy generation have to be explored. The same applies to the considerations for the embodied energy in the production of the façade source materials as well as related semi-finished and finished products. Add to that the final criterion of focusing on recycling used materials and feeding them back into the manufacturing process.
Architects continue to look for new ways to express their ideas. Three-dimensional computer modelling has opened up the possibility of free-form shapes in the design repertoire for architects; however, this entails the search for suitable construction and manufacturing methods. Often it is the architectural vision which, even though not yet realizable, drives new technological developments.
