GLASS SANDWICH FACADES
The Glass Sandwich Façade is a warm façade and consists of transparent and opaque areas. The Glass Sandwich Façade combines the opaque Glass Sandwich Panel (GSP) with conventional window and façade frame profiles. There are many different design options. Through partnerships with suppliers of façade systems, iconic skin is compatible at all the relevant interfaces.
The Glass Sandwich Panel (GSP) consists of an outer printed glass sheet bonded to a standard sandwich panel. This creates a glass exterior in the form of panels up to a height of 16 m. This results in a homogeneous and flush façade surface in glass.
This paper discusses research and development with a main focus on structural testing and numerical verification of the glass sandwich panel. Furthermore, it is shown how to integrate window and door elements flush with the façade surface.
GLAZED MULTILAYERED BUILDING ENVELOPES
Starting with a discussion and subsequent classification of double-skin facade systems the authors will focus on the latest concepts that have evolved within this construction typology (i.e. closed cavity facade, self conditioned facade). Following a review of design objectives and considerations on more common double skin facades, the paper will touch on benefits as well as challenges that are inherent when designing for a non accessible space between two glass units. Both systems, the actively pressurized and the passive self conditioned, are characterized by a confined volume. Delicate design is required to manage condensation and contamination.
The paper will end with a critical reflection on limitations and briefly discuss the opposing target to minimize material and embodied energy in light of the European Union’s Roadmap 2050.
