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.
