Modern architecture continues to produce ever more attractive and higher quality façade constructions. Previously build – only based on general experience, now often sophisticated structural analysis is necessary to design a façade – but the structural design is often forgotten due to a lack of knowledge (structural and architectural design). At present we see damages to old facades but also to new constructions. These problems are increasing, up to collapsing façade elements. This concerns of course also high rising buildings. First typically problems with facades are presented (due to analysis, regulations, design and execution). Aspects of inspection of hidden parts (brackets or gluing on the back) or possibilities for strengthening becomes more and more important. A code for monitoring is presented. The monitoring of glass-facades is investigated in an actual research work with the title “Evaluation of the Current in Situ Stress Condition in Glass”. First results of the practical application of the device are presented.
