Bioclimatic Design & Rainscreen Systems

2022 was our seventh workshop event.

The workshop explored the potential of terra cotta for bioclimatic façade design, the use of rainscreen systems in historic restoration, and the sculptural possibilities of the material as architectural surface, exhibition display, and urban furniture.

2022 TEAMS

BKSK is developing a highly reflective glaze for an architectural terracotta façade brise soleil that would increase the energy harvest of building integrated PV panels above it as well as effectively shade fenestration below it. 

BNIM is studying an ornamental terra-cotta band that can be integrated into a typical masonry rainscreen wall. The terra-cotta band manifests as a decorative trim piece which will be coursed into the brick rainscreen, as well as a horizontal louver which provides solar shading for windows in the façade.

FXCollaborative is designing a system to control and play with light through a perforated facade. A series of light channels are designed to bounce and “sculpt” light for viewing through a traditionally glazed facade.

NADAAA is designing an ambitious sculptural unit for a major museum exhibition. The object acts as both a pedestal for historic artifacts as well as a sculptural moment for the larger exhibit.

Pelli Clarke & Partners is developing outdoor/urban furniture, focussing on using terracotta for freestanding, modular elements that can define and support outdoor space and activities. They are using slip cast manufacturing to better accommodate self-supporting terracotta fabrications in-the-round.

Steven Holl Architects’ project is guided by material exploration and aesthetic offerings of terra cotta. There are two paths being investigated: research for the exterior use of terra cotta is focused on extruded panels for precast, while the interior project is decidedly sculptural in nature.

WJE is developing a terra cotta rainscreen system that replicates a historic terra cotta cornice assembly using modern thin-walled terra cotta extrusions and modular attachments. The team developed terra cotta unit profiles that could be economically extruded and hung from a unique anchorage system that can be integrated into a historic masonry backup assembly in order to reduce installation costs.

Woods Bagot is working on a holistic design of a facade system that incorporates PV panels and Terra Cotta. They are aiming to utilize the building facade as a place to capture and create energy.

“Orange County Art Museum, From ACAW to Reality”
This year’s conference kicks off with a live-only opening keynote from Stan Su & Eric Verboon that discusses the process of designing the skin for the Orange County Museum of Art, by Morphosis Architects. The recently completed 53,000 sq. foot terra cotta assembly had its roots at ACAW as a concept exploration.
