a "spandrel" typically refers to the space or panel located between two architectural elements. Specifically, in multi-story buildings, a spandrel is the area between the top of a window on one floor and the sill of the window directly above it on the next floor. This space can be filled with various materials, such as glass, metal, or stone, and is often used to conceal structural elements or mechanical systems.

Spandrels can serve both aesthetic and functional purposes. Aesthetically, they contribute to the building's facade design, providing continuity or contrast between floors. Functionally, they can offer insulation, fire resistance, and weatherproofing, depending on the materials used. In some cases, spandrels may also house components of the building's HVAC or electrical systems.

In Australian commercial construction, the design and material selection for spandrels must comply with local building codes and standards, which address factors such as thermal performance, fire safety, and structural integrity.

It's worth noting that the specific definition and application of spandrel may vary depending on the context and project requirements. However, in general, spandrels play a crucial role in the thermal performance and structural integrity of commercial buildings in Australia.

Key Characteristics of Spandrels in Australian Commercial Construction

• Non-structural infill panels
• Typically located between window sill and window head
• Often made of precast concrete
• Defined width of 127 mm for edge region
• Plays a role in thermal performance and structural integrity
