Project R-12223

Mechanical and functional performance of structural hybrid timber-photovoltaic glass façade systems (Research)

In this project, the structural and functional performance of hybrid timber-photovoltaic glass façade systems is investigated. Traditionally, the horizontal stability of timber frame structures, the so-called racking resistance, is ensured by opaque diaphragm panels or steel bracings. Here, glass panels are used as a structural bracing element, opening the door to extremely transparent timber-based load-bearing systems. The idea of this hybrid timber-glass façade system is taken even further in this project by including photovoltaics (PV) in its glazing. Rather than being a traditional passive element in the building system, the glazing now acts as both a loadbearing and energy-generating element. Since the glazing is subjected to higher loads, additional stresses and strains are imposed into the PV module laminates, requiring a proper investigation of the durable functionality of these laminates under such load-bearing circumstances. A combined numerical-experimental approach is followed in this study to investigate the structural as well as the functional performance of the novel hybrid system. The results are synthesized into practical design guidelines and calculation methods.
