Abstract
The FACEcamp project tackles the challenge of Complex Fenestration System (CFS) performances. Nowadays, a practical relevant issue connected to one specific technology within the CFS family (the Double Skin Façade – Window box type) concerns the characterisation of the whole façade construction, depending from the kind of air cavity ventilation regimes. Starting from this, the choice has been taken to design and realise a window-box façade specimen able to be configured with different air-cavity ventilation regimes, as well as to fit with the two kind of outdoor laboratories (EURAC and UIBK).
