The purpose of the association is to develop and implement educational services in the field of building envelopes. It is also dedicated to the further development of the building envelope profession. The association operates the necessary training centers, currently in Uzwil and Les Paccots. It can establish, acquire and operate additional training centers and institutions that serve the purpose of the association directly or indirectly (such as for the accommodation of course participants). As a rule, the association does not acquire properties. The properties required for the pursuit of the purpose (namely for the training centers) are instead owned by the Polybau Foundation and the Gebäudehülle Schweiz cooperative, which conclude long-term rental agreements with the association.
